Description

[Technical field]

[0001] The present disclosure relates to a decorative laminate, a transfer sheet, a decorative member, a movable body, and a method for manufacturing a decorative laminate. [Background technology]

[0002] Decorative members and decorative laminates for decorating interior and exterior products of automobiles (instrument panels, etc.), home appliances, houses, etc. are known (see, for example, Patent Document 1). Patent Document 1 discloses a decorative member including a Fresnel lens layer in which a Fresnel lens structure that functions as a Fresnel lens is formed. Such a Fresnel lens layer is formed by shaping a resin using a shaping mold.

[0003] The shaping mold is produced, for example, as follows. First, a master mold is prepared in which a concave-convex structure corresponding to a desired Fresnel lens structure is formed by cutting. Next, a metal layer that will become the shaping mold is formed on the concave-convex structure of the master mold by electroforming. Next, the metal layer is separated from the master mold. This produces a shaping mold having a concave-convex structure corresponding to the concave-convex structure of the master mold. [Prior art documents] [Patent documents]

[0045] Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings. In the drawings attached to this specification, the scale and the aspect ratio are appropriately changed and exaggerated from those of the actual objects for the convenience of illustration and understanding.

[0046] In order to clarify the relationship between directions between the drawings, common directions are indicated by arrows with common symbols in several drawings. The tip of the arrow is one side of each direction. An arrow pointing into the paper in a direction perpendicular to the paper of the drawing is indicated by a symbol with an X in a circle, as shown in FIG. 2, for example. Furthermore, an arrow pointing toward the viewer in a direction perpendicular to the paper of the drawing is indicated by a symbol with a dot in a circle, as shown in FIG. 4, for example. The number of inclined surfaces 26A and connecting surfaces 26B, which will be described later, in the drawings may be appropriately changed from one drawing to another in order to simplify the drawings.

[0047] As used in this specification, terms specifying shapes, geometric conditions, and the extent thereof, such as "parallel," "perpendicular," and "same," as well as values ​​of lengths and angles, are not limited to their strict meanings, but are interpreted to include a range within which similar functions can be expected.

[0048] In this specification, terms such as "film," "sheet," and "plate" are not distinguished from one another solely on the basis of differences in name. For example, a "transfer sheet" cannot be distinguished from a member called a transfer film solely on the basis of differences in name.

[0049] In this specification, when multiple upper limit candidates and multiple lower limit candidates are given for a certain parameter, the numerical range of the parameter may be formed by combining any one of the upper limit candidates and any one of the lower limit candidates. As an example, consider the description "Parameter B may be A1 or more, A2 or more, or A3 or more. Parameter B may be A4 or less, A5 or less, or A6 or less." In this example, the numerical range of parameter B may be A1 or more and A4 or less, A1 or more and A5 or less, A1 or more and A6 or less, A2 or more and A4 or less, A2 or more and A5 or less, A2 or more and A6 or less, A3 or more and A4 or less, A3 or more and A5 or less, or A3 or more and A6 or less.

[0050] In this specification, "suppress" means to hold back the realization, occurrence, etc., or to prevent the realization, occurrence, etc. "Suppress" means not only to completely prevent the realization, occurrence, etc., but also to reduce the possibility of the realization, occurrence, etc., or to make the realization, occurrence, etc. less likely to occur.

[0051] 1A, 1B, 2A, 3 to 10E are diagrams for explaining one embodiment. Among these, Fig. 1A and Fig. 1B are diagrams showing an application example of a decorative member 3 including a decorative laminate 10. The decorative laminate 10 is formed in a sheet shape and is also called a decorative sheet. The decorative laminate 10 displays a design and imparts design to an article (decorative member 3 in the example shown in Fig. 1A) to which the decorative laminate 10 is applied.

[0052] In the example shown in FIG. 1A, the decorative member 3 is used in a moving body 1. In the illustrated example, the decorative member 3 is installed on a front panel 2 of the moving body 1. As described later, the decorative member 3 includes a decorative laminate 10. Therefore, the moving body 1 equipped with the decorative member 3 includes the decorative laminate 10. The front panel 2 is formed as a front grill in an engine vehicle. On the other hand, in an electric vehicle, a heat exchanger to be air-cooled, such as a radiator, may not be installed. Therefore, the front panel 2 does not have to be formed as a grill with a large number of holes formed therein.

[0053] Hereinafter, one embodiment will be described with reference to specific application examples shown in the drawings. The moving body 1 shown in FIG. 1A is an automobile. However, the moving body 1 to which the decorative member 3 is applied is not limited to an automobile. The decorative member 3 can also be applied to other moving bodies 1 as movable devices. Examples of moving bodies 1 other than automobiles include railroad cars, dollies, ships, airplanes, helicopters, drones, and robots. The decorative member 3 and the decorative laminate 10 may be used in the interior body of a moving body. The decorative member 3 and the decorative laminate 10 can also be applied to building materials such as interior materials, exterior materials, ceiling materials, and floor materials, as well as home appliance cases, communication device housings, and cosmetic containers. More specifically, the decorative member 3 and the decorative laminate 10 can also be applied to smartphone housings and smartphone covers.

[0054] <<Decorative materials>> First, the overall configuration of the decorative member 3 will be described with reference to FIG. 1B. As shown in FIG. 1B, the decorative member 3 has a front side surface 3a and a back side surface 3b facing the front side surface 3a. The front side surface 3a and the back side surface 3b extend along a front side surface 66 and a back side surface 67 of a molded portion 65, which will be described later, respectively. In the illustrated example, the front side surface 3a and the back side surface 3b extend in a planar shape in the X direction Dx and the Y direction Dy perpendicular to the X direction Dx, respectively. The front side surface 3a and the back side surface 3b face each other in the Z direction Dz perpendicular to both the X direction Dx and the Y direction Dy. The Z direction Dz coincides with the normal direction of the decorative laminate 10. However, this is not limited to this example, and the front side surface 3a and the back side surface 3b may be curved.

[0055] 1B, the decorative member 3 includes a molded portion 65 and a decorative laminate 10 covering at least a portion of the molded portion 65. In the example shown in FIG. 1B, the molded portion 65 and the decorative laminate 10 are laminated in this order in a direction from the back side surface 3b toward the front side surface 3a of the decorative member 3 (Z direction Dz). In the example shown in FIG. 1B, the decorative member 3 is disposed facing the sensor 5. In the example shown in FIG. 1B, the molded portion 65 faces the sensor 5, and the decorative laminate 10 faces the observer 6.

[0056] The decorative laminate 10 has a front side surface 11 and a back side surface 12. In the example shown in FIG. 1B, the front side surface 11 forms the front side surface 3a of the decorative member 3. The back side surface 12 faces the back side surface 3b side (the molded portion 65 side) of the decorative member 3. The front side surface 11 and the back side surface 12 extend along the front side surface 66 of the molded portion 65 described later. In the illustrated example, the front side surface 11 and the back side surface 12 extend in a planar shape in the X direction Dx and the Y direction Dy, respectively. The front side surface 11 and the back side surface 12 face each other in the Z direction Dz. However, this is not limited to this example, and the front side surface 11 and the back side surface 12 may be curved.

[0057] The molded portion 65 has a front side surface 66 and a rear side surface 67. The rear side surface 67 forms the rear side surface 3b of the decorative member 3. The front side surface 66 faces the front side surface 3a side (the decorative laminate 10 side) of the decorative member 3. In the illustrated example, the front side surface 66 and the rear side surface 67 extend in a planar shape in the X direction Dx and the Y direction Dy, respectively. The front side surface 66 and the rear side surface 67 face each other in the Z direction Dz. However, this is not limited to this example, and the front side surface 66 and the rear side surface 67 may be curved.

[0058] The molded portion 65 may be formed from various materials such as a resin material or glass. There is no particular limitation on the resin material forming the molded portion 65. Examples of the resin material forming the molded portion 65 include polymethyl methacrylate (PMMA), polypropylene (PP), polycarbonate (PC), acrylonitrile-butadiene-styrene (ABS), acrylonitrile-ethylene-propylene-diene-styrene (AES), and acrylonitrile-styrene-acrylate (ASA).

[0059] The molded portion 65 may be colored. In this case, the desired color can be imparted to the decorative member 3. The molded portion 65 may be transparent or opaque. When the molded portion 65 is opaque, it can conceal at least a part of the article to which the decorative member 3 is applied. For example, in the example shown in FIG. 1B, the molded portion 65 is opaque, so that the decorative member 3 can conceal the sensor 5. The colored molded portion 65 can be made of the same material as the colored layer 45 described later.

[0060] In addition, the term "transparent" used in this specification means that the total light transmittance is 50% or more when measured using a haze meter ("HM-150N" manufactured by Murakami Color Research Laboratory Co., Ltd., compliant with JIS K7361:1997). Materials and members referred to as being transparent in this specification preferably have a total light transmittance of 80% or more when measured by the above-mentioned method.

[0061] Incidentally, as shown in FIG. 1B, the decorative member 3 may be disposed facing a sensor 5 that uses electromagnetic waves with a longer wavelength than visible light. As an example, the sensor 5 may monitor the surroundings of the moving body 1. The detection result of the sensor 5 may be transmitted to a control device 4 of the moving body 1. The control device 4 may issue an alarm or control the movement of the moving body 1 based on the detection result of the sensor 5. For example, the sensor 5 may detect an obstacle or the like in front of the moving body 1. This sensor 5 may be capable of transmitting electromagnetic waves and receiving electromagnetic waves. The sensor 5 can detect the presence or absence of an obstacle and the distance to the obstacle by receiving a reflected wave reflected by an obstacle or the like. The sensor 5 may be a millimeter wave radar device. The millimeter wave radar device may use millimeter waves with a wavelength of 1 mm or more and 10 mm or less as electromagnetic waves. Alternatively, the sensor 5 may be a lidar device. The lidar device may use infrared rays as electromagnetic waves.

[0062] The sensor 5 faces the back side surface 3b of the decorative member 3. The electromagnetic waves used by the sensor 5 pass through the decorative member 3 along the Z direction Dz. In the example shown in FIG. 1B, the front side surface 3a and the back side surface 3b are the emission surface and the incidence surface of the electromagnetic waves. It is preferable that the front side surface 3a and the back side surface 3b are flat surfaces at least in the area facing the sensor 5 in the Z direction Dz. By making the front side surface 3a and the back side surface 3b flat surfaces, it is possible to suppress a decrease in the sensitivity of the sensor 5 due to the diffusion of the electromagnetic waves.

[0063] <<Decorative laminate>> Next, the decorative laminate 10 will be described in more detail. Fig. 2A is a cross-sectional view showing the configuration of a decorative member 3 according to one embodiment. Fig. 3 is a plan view of the decorative laminate 10. Fig. 4 is an enlarged view of an area U surrounded by a two-dot chain line in Fig. 3. Area U is an area located inside area 20I in plan view. Fig. 5 is a cross-sectional view taken along line VV in Fig. 4.

[0064] As shown in FIG. 3 and FIG. 4, the decorative laminate 10 includes an object region 91 that displays an object 90, and a background region 92 located around the object region 91. The object 90 is a display of letters, numbers, characters, patterns, geometric figures, logos, brand marks, emblems, and the like. The background of the object 90 is displayed in the background region 92. In the example shown in FIG. 3, the object region 91 divides the background region 92 into a plurality of regions. The object region 91 may divide the background region 92 into three or more regions. In the example shown in FIG. 3, the object region 91 divides the background region 92 into a first background region 92a, a second background region 92b, a third background region 92c, a fourth background region 92d, and a fifth background region 92e. The object region 91 surrounds the first background region 92a, the second background region 92b, the third background region 92c, and the fourth background region 92d. The object region 91 is surrounded by the fifth background region 92e.

[0065] In the example shown in FIG. 3, the background region 92 surrounds the object region 91 from the periphery. In the example shown in FIG. 3, the background region 92 is adjacent to the object region 91 without providing a space therebetween. However, the form of the background region 92 is not limited to this. The background region 92 may be located in a part of the periphery of the object region 91 without surrounding the object region 91 from the periphery. A space may be provided between the object region 91 and the background region 92. That is, the background region 92 being located in the periphery of the object region 91 includes the background region 92 being located in a part of the periphery of the object region 91 without surrounding the object region 91 from the periphery. Furthermore, the background region 92 being located in the periphery of the object region 91 includes the case where a space is provided between the object region 91 and the background region 92. When a space is provided between the object region 91 and the background region 92, the space may have an appearance different from that of the object region 91 and the background region 92. As an example, in the space, the shaping surface 20a of the shaping layer 20 described later is flat. When a space is provided between the object region 91 and the background region 92, the distance between the object region 91 and the background region 92 is, for example, 5.0 mm or less.

[0066] As shown in FIG. 2A and FIG. 5, the decorative laminate 10 includes a shape-imparting layer 20. The shape-imparting layer 20 extends over the object region 91 and the background region 92. In this embodiment, the shape-imparting layer 20 extends over the entire object region 91 and the background region 92. As shown in FIG. 5, the shape-imparting layer 20 has a shape-imparting surface 20a on which a concave-convex structure 25 is formed. The shape-imparting layer 20 has a non-shape-imparting surface 20b located on the opposite side to the shape-imparting surface 20a. The decorative laminate 10 shown in FIG. 2A and FIG. 5 further includes a brightness adjustment layer 30. The brightness adjustment layer 30 covers the shape-imparting surface 20a. As shown in FIG. 4, the decorative laminate 10 includes at least one unit optical element 13. Each unit optical element 13 reflects, refracts, and / or diffracts light incident on the front side surface 3a according to the concave-convex structure 25 of the shape-imparting surface 20a. This allows the decorative laminate 10 to express a three-dimensional effect that is greater than the thickness of the decorative laminate 10. This results in improved design of the decorative laminate 10. In the illustrated example, the decorative laminate 10 has a plurality of unit optical elements 13. This allows the decorative laminate 10 to be given a complex design by combining a plurality of unit optical elements 13.

[0067] The decorative laminate 10 may include other layers. For example, in the example shown in FIG. 2A and FIG. 5, the decorative laminate 10 includes a bonding layer 38 and a functional layer 37. In this example, the bonding layer 38, the brightness adjustment layer 30, the molding layer 20, and the functional layer 37 are laminated in this order in a direction from the back side surface 12 toward the front side surface 11 of the decorative laminate 10. In this example, the functional layer 37 forms the front side surface 11 of the decorative laminate 10, and the bonding layer 38 forms the back side surface 12 of the decorative laminate 10. The molding layer 20 is disposed between the front side surface 11 of the decorative laminate 10 and the brightness adjustment layer 30. The brightness adjustment layer 30 is disposed between the back side surface 12 of the decorative laminate 10 and the molding layer 20. The molding layer 20 may form the front side surface 11 of the decorative laminate 10. The brightness adjustment layer 30 may form the back side surface 12 of the decorative laminate 10.

[0068] <Shaping layer> The shaping layer 20 will be described. The decorative laminate 10 has at least one unit shaping element 23. In the example shown in FIG. 4, the shaping layer 20 has a plurality of unit shaping elements 23. By including a plurality of unit shaping elements 23 in the shaping layer 20, a plurality of unit optical elements 13 can be formed in the decorative laminate 10. One unit shaping element 23 corresponds to one unit optical element 13. On the shaping surface 20a, each unit shaping element 23 has a concave-convex structure 25 formed therein. The concave-convex structure 25 can be formed by shaping the shaping layer 20 using a shaping mold 100 described below.

[0069] The unit optical element 13 is formed in at least a part of at least one of the background region 92 and the object region 91. In this embodiment, the unit shaping element 23 is formed on the shaping surface 20a in at least a part of at least one of the background region 92 and the object region 91. Therefore, the uneven structure 25 is formed on the shaping surface 20a in at least a part of at least one of the background region 92 and the object region 91 of the shaping layer 20. By forming the unit shaping element 23 as described above, the unit optical element 13 corresponding to the unit shaping element 23 is formed in at least a part of at least one of the background region 92 and the object region 91. In this embodiment, the unit shaping element 23 is formed on the shaping surface 20a in the background region 92. As a result, the unit optical element 13 is formed in the background region 92. The unit optical element 13 formed in the background region 92 is also referred to as a first unit optical element. In the example shown in FIG. 4, a plurality of unit optical elements 13 are formed in the background region 92. In other words, the decorative laminate 10 has a plurality of first unit optical elements as a plurality of unit optical elements 13. The unit shaping element 23 may be formed on the shaping surface 20a in the entire background region 92. In this case, the unit optical element 13 is formed on the entire background region 92. In the decorative laminate 10 of this embodiment, the unit shaping element 23 is formed on the shaping surface 20a in each of the plurality of regions formed by dividing the background region 92 by the object region 91. Therefore, the unit optical element 13 is formed in each of the plurality of regions formed by dividing the background region 92 by the object region 91. In the decorative laminate 10 of this embodiment, the unit shaping element 23 is formed on the shaping surface 20a in each of the first background region 92a, the second background region 92b, the third background region 92c, the fourth background region 92d, and the fifth background region 92e. Therefore, unit optical elements 13 are formed in each of the first background region 92a, the second background region 92b, the third background region 92c, the fourth background region 92d, and the fifth background region 92e.

[0070] The unit optical element 13 may be formed in one of the background region 92 and the object region 91. In this case, the unit shaping element 23 is formed on the shaping surface 20a in one of the background region 92 and the object region 91. In the example shown in FIG. 4 and FIG. 5, the unit optical element 13 is formed in the background region 92. In this case, the unit shaping element 23 is formed on the shaping surface 20a in the background region 92. In the example shown in FIG. 4 and FIG. 5, the unit optical element 13 is not formed in the object region 91. In this case, the unit shaping element 23 is not formed on the shaping surface 20a in the object region 91. In the example shown in FIG. 4 and FIG. 5, the shaping surface 20a is flat in the object region 91.

[0071] In the illustrated example, the imprinting surface 20a is covered with a single covering layer in the object region 91 and the background region 92. In the example shown in FIG. 5, the part of the imprinting surface 20a located in the object region 91 and the part of the imprinting surface 20a located in the background region 92 are both covered with the brightness adjustment layer 30. In this case, the brightness adjustment layer 30 corresponds to a single covering layer that covers the imprinting surface 20a in the object region 91 and the background region 92. In the example shown in FIG. 5, the single covering layer (brightness adjustment layer 30) is in contact with the part of the imprinting surface 20a located in the object region 91 and the part of the imprinting surface 20a located in the background region 92. The single covering layer (brightness adjustment layer 30) covers the entire part of the imprinting surface 20a located in the object region 91 and the entire part of the imprinting surface 20a located in the background region 92. In this embodiment, a reflection interface 27 is formed between the imprinting surface 20a of the imprinting layer 20 and the covering layer that covers the imprinting surface 20a.

[0072] In the example shown in FIG. 4, a plurality of unit shaping elements 23 are formed in the background region 92. Each of the plurality of unit shaping elements 23 has a concave-convex structure 25 formed on the shaping surface 20a. The concave-convex structure 25 can be formed by shaping the shaping layer 20 using a shaping mold 100 described later. In the example shown in FIG. 3, the decorative laminate 10 has a region 20I. The region 20I is a region that combines the object region 91 and the background region 92. In this embodiment, the entire portion of the shaping layer 20 located in the region 20I is shaped by one shaping mold 100. In other words, in the decorative laminate 10 of this embodiment, the shaping layer 20 is shaped by one shaping mold 100.

[0073] The uneven structure 25 formed on the shaping surface 20a provides an optical effect corresponding to the uneven structure 25 to the light incident on the unit optical element 13. The unit optical element 13 reflects, refracts, and / or diffracts the incident light according to the uneven structure 25. In the illustrated example, the shape of the uneven structure 25 is determined so as to converge and / or diverge the parallel light incident on the front surface 11 of the decorative laminate 10. The whole or part of each unit optical element 13 may be configured to collect the light incident from the front surface 11 of the decorative laminate 10. In this specification, a lens configured to collect the light incident from the front surface 11 of the decorative laminate 10 is referred to as a "convex lens". A convex lens is a lens configured to provide an optical effect similar to that of a convex mirror. A lens configured to diverge the light incident from the front surface 11 of the decorative laminate 10 is referred to as a "concave lens". A concave lens is a lens configured to provide an optical effect similar to that of a concave mirror. In the example shown in FIG. 5, when the decorative laminate 10 is observed from the front surface 11 side, the entire unit optical element 13 functions as a convex lens. A part of the unit optical element 13 may function as a convex lens. The entire or a part of the unit optical element 13 may function as a concave lens. By making the entire or a part of the unit optical element 13 function as a convex or concave lens, the decorative laminate 10 can express a design with more depth than the actual thickness of the decorative laminate 10. This allows the decorative laminate 10 to express a three-dimensional effect. Therefore, the decorative laminate 10 can realize a rich design expression with a sense of luxury.

[0074] The dimensions of each unit shaping element 23 in the plan view of the decorative laminate 10 (therefore, the dimensions of each unit optical element 13) are not particularly limited and can be appropriately set according to the design expressed by the decorative laminate 10. However, from the viewpoint of making the visual effect of the unit optical elements 13 effective, it is preferable that each unit shaping element 23 has a size that can be distinguished by the naked eye. Specifically, the shortest length of the unit shaping element 23 may be 1.0 mm or more, 10 mm or more, or 20 mm or more. In addition, the longest length of the unit shaping element 23 may be 200 mm or less, or 100 mm or less. The dimensions of each unit shaping element 23 in the plan view of the decorative laminate 10 may be 1.0 mm or more and 200 mm or less.

[0075] In the unit optical element 13, the shaping surface 20a includes a plurality of inclined surfaces 26A and a plurality of connecting surfaces 26B. In the example shown in Fig. 4 and Fig. 5, each unit shaping element 23 corresponding to each unit optical element 13 has a plurality of inclined surfaces 26A and a plurality of connecting surfaces 26B. As a result, a plurality of inclined surfaces 26A and a plurality of connecting surfaces 26B are formed in each unit optical element 13.

[0076] The inclined surfaces 26A are aligned in a direction toward a reference line extending along the normal direction (Z direction Dz) of the decorative laminate 10 and are inclined toward the reference line. The connecting surfaces 26B connect adjacent inclined surfaces 26A. Regarding the inclined surfaces 26A, "aligned in a direction toward the reference line and inclined toward the reference line" means the following. Consider an arbitrary cross section along the direction in which the inclined surfaces 26A are aligned and parallel to the normal direction of the decorative laminate 10. FIG. 5 corresponds to a cross section along the direction in which the inclined surfaces 26A are aligned and parallel to the normal direction of the decorative laminate 10. "Aligned in a direction toward the reference line and inclined toward the reference line" means that on the arbitrary cross section, the inclined surfaces 26A are aligned in a direction toward the reference line and inclined toward the reference line. In the illustrated example, the multiple inclined surfaces 26A are aligned in a direction toward a first reference line L1 extending along the normal direction of the decorative laminate 10 and are inclined toward the first reference line L1. The unit optical element 13 including the multiple inclined surfaces 26A aligned in a direction toward the reference line and inclined toward the reference line includes a unit optical element 13 including a multiple first inclined surfaces 26A1 aligned in a direction toward the first reference line L1 and inclined toward the first reference line L1, and a multiple second inclined surfaces 26A2 aligned in a direction toward the second reference line L2 and inclined toward the second reference line L2, on any of the above cross sections.

[0077] The plurality of inclined surfaces 26A and the plurality of connecting surfaces 26B provide the light incident on the unit optical element 13 with an optical effect according to the shapes of the plurality of inclined surfaces 26A and the plurality of connecting surfaces 26B.

[0078] In the example shown in FIG. 4 and FIG. 5, the inclined surfaces 26A are lens surfaces. In other words, the inclined surfaces 26A correspond to a plurality of lens surfaces obtained by dividing a continuous lens surface along a surface perpendicular to the thickness direction. In the example shown in FIG. 4 and FIG. 5, the connecting surfaces 26B are rise surfaces. In other words, the connecting surfaces 26B correspond to rise surfaces connecting adjacent lens surfaces. According to such a concave-convex structure 25, the unit optical element 13 can function as a lens. Furthermore, according to such a concave-convex structure 25, an increase in the thickness of the decorative laminate 10 caused by making the unit optical element 13 function as a lens can be effectively suppressed. For example, as in the illustrated example, when the decorative member 3 is used in the front grille of a vehicle, the decorative member 3 may be required to be thin from the viewpoint of weight reduction. In addition, when the decorative member 3 is disposed facing the sensor 5, the decorative laminate 10 is required to transmit the electromagnetic wave emitted from the sensor 5 through the decorative member 3 with high transmittance. In this case, it is preferable to reduce the thickness of the decorative laminate 10. The inclined surfaces 26A are lens surfaces, and the connecting surfaces 26B are rise surfaces, so that the unit optical elements 13 function as lenses. This allows the decorative laminate 10 to express a three-dimensional effect that is greater than the thickness of the decorative laminate 10 in the area where the unit optical elements 13 are located.

[0079] The shaping surface 20a forms a reflective interface 27 that reflects light. In the example shown in FIG. 5, a reflective interface 27 having a shape corresponding to the shape of the uneven structure 25 of the shaping surface 20a is formed between the shaping surface 20a and the brightness adjustment layer 30 that covers the shaping surface 20a. In the example shown in FIG. 5, the reflective interface 27 is formed at the position of the shaping surface 20a. Although not shown, the reflective interface 27 may be formed at a position away from the shaping surface 20a in the normal direction of the decorative laminate 10 of the inclined surface 26A. That is, the position of the shaping surface 20a formed by shaping and the position of the reflective interface 27 that has a shape corresponding to the shape of the shaping surface 20a and reflects light may be different.

[0080] The angle of the inclined surface 26A with respect to the normal direction (Z direction Dz) of the decorative laminate 10 is larger than the angle of the connection surface 26B connected to the inclined surface 26A with respect to the normal direction of the decorative laminate 10. Specifically, the angle θC of the inclined surface 26A with respect to the normal direction described below is larger than the angle θB of the connection surface 26B connected to the inclined surface 26A with respect to the normal direction of the decorative laminate 10. The maximum value of the inclination angle θA of the tangent plane in contact with the inclined surface 26A with respect to the normal direction of the decorative laminate 10 is the angle θC. The maximum value of the inclination angle of the tangent plane in contact with the connection surface 26B adjacent to the inclined surface 26A with respect to the normal direction of the decorative laminate 10 is the angle θB. The angle θB is also referred to as the rise angle θB. When the inclined surface 26A has a portion perpendicular to the normal direction of the decorative laminate 10 and the connecting surface 26B does not have a portion perpendicular to the normal direction of the decorative laminate 10, the angle θC is deemed to be greater than the angle θB.

[0081] In the example shown in FIG. 5, a part of the shaping surface 20a of the shaping layer 20 that forms the unit optical element 13 forms a curved surface 25a that protrudes from the back surface 12 toward the front surface 11 in the normal direction of the decorative laminate 10. In the example shown in FIG. 4 and FIG. 5, the concave-convex structure 25 of each unit optical element 13 has a Fresnel lens structure. In this case, the multiple inclined surfaces 26A correspond to multiple lens surfaces obtained by dividing the lens surface of a curved lens such as a spherical lens or a cylindrical lens into multiple parts along a surface perpendicular to the thickness direction (optical axis direction) of the curved lens. The multiple connecting surfaces 26B correspond to rise surfaces that connect the multiple lens surfaces. In this embodiment, the concave-convex structure 25 of each unit optical element 13 is a linear Fresnel lens or has a structure in which linear Fresnel lenses are combined. In particular, the concave-convex structure 25 of each unit optical element 13 shown in FIG. 4 has a structure in which linear Fresnel lenses are combined. For this reason, when the decorative laminate 10 is observed from the front surface 11 side, the unit optical elements 13 as a whole function as a convex lens. Each unit optical element 13 in this embodiment has an optical axis Ax.

[0082] In this embodiment, the unit optical elements 13 are formed in the background region 92. The portion of the shaping surface 20a located in the object region 91 is a flat surface perpendicular to the normal direction (Z direction Dz) of the decorative laminate 10. In this case, the action of the unit optical elements 13 can give an impression that the distance between the shaping surface 20a in the background region 92 and the shaping surface 20a in the object region 91 in the normal direction of the decorative laminate 10 is greater than the actual distance. Specifically, the unit optical elements 13 provided in the background region 92 function as convex lenses, so that a person viewing the decorative laminate 10 can be given the impression that the background region 92 is deeper than the object region 91. Therefore, a person viewing the decorative laminate 10 can be given the impression that the object 90 stands out from the background region 92. Since the decorative laminate 10 has a plurality of unit optical elements 13, a complex design by combining a plurality of unit optical elements 13 can be imparted to the decorative laminate 10.

[0083] In the illustrated example, the multiple unit shaping elements 23 have the same shape in the plan view of the decorative laminate 10, except for the unit shaping elements 23 adjacent to the boundary 93 between the background region 92 and the object region 91. For this reason, the multiple unit optical elements 13 have the same shape in the plan view of the decorative laminate 10, except for the unit optical elements 13 adjacent to the boundary 93 between the background region 92 and the object region 91. In the illustrated example, the multiple unit shaping elements 23 are regularly arranged in the region 20I. For this reason, the multiple unit optical elements 13 are regularly arranged. In particular, the multiple unit shaping elements 23 are regularly arranged in the background region 92. For this reason, the multiple unit optical elements 13 are regularly arranged in the background region 92. In the illustrated example, the unit shaping elements 23 adjacent to the boundary 93 between the background region 92 and the object region 91 have a shape in which a part of the unit shaping elements 23 located at a position away from the boundary 93 is cut out on a virtual plane. The virtual surface is a surface parallel to the normal direction (Z direction Dz) of the decorative laminate 10. The unit shaping element 23 adjacent to the boundary 93 is disposed in the background region 92 so that the virtual surface overlaps with the boundary 93 in a plan view.

[0084] In the example shown in FIG. 4 and FIG. 5, the unit optical element 13 includes the first region 234. In the example shown in FIG. 4 and FIG. 5, each of the multiple unit optical elements 13 includes the first region 234. The multiple tilt surfaces 26A include at least one first tilt surface 26A1 arranged in the first region 234. In this embodiment, the multiple tilt surfaces 26A include multiple first tilt surfaces 26A1. The multiple connection surfaces 26B include at least one first connection surface 26B1 that connects adjacent first tilt surfaces 26A1. The multiple connection surfaces 26B include multiple first connection surfaces 26B1. In the example shown in FIG. 4 and FIG. 5, the multiple first tilt surfaces 26A1 are flat surfaces. The multiple first tilt surfaces 26A1 correspond to multiple lens surfaces obtained by dividing a continuous lens surface along a surface perpendicular to the thickness direction. The first connecting surfaces 26B1 correspond to the rise surfaces that connect the first inclined surfaces 26A1 corresponding to the lens surfaces. In the example shown in FIG. 4 and FIG. 5, each of the first inclined surfaces 26A1 is configured to have a function corresponding to each of the curved surfaces formed by dividing a continuous convex lens surface. By adjusting the inclination of the first inclined surfaces 26A1, which are flat surfaces, each of the first inclined surfaces 26A1 can be configured to have a function corresponding to each of the curved surfaces formed by dividing a continuous convex lens surface. Although not shown, each of the first inclined surfaces 26A1 may be a curved surface having a shape formed by dividing a continuous convex lens surface. Such a plurality of first inclined surfaces 26A1 can make the unit optical element 13 function as a convex lens while keeping the thickness of the mold layer 20 small.

[0085] As described above, the multiple inclined surfaces 26A are aligned in a direction toward a reference line extending along the normal direction (Z direction Dz) of the decorative laminate 10 and are inclined toward the reference line. Multiple inclined surfaces aligned continuously at a position close to the reference line are referred to as reference line-proximate inclined surfaces. In the example shown in FIG. 5, the reference line (first reference line L1) passes through the first region 234. Multiple first inclined surfaces 26A1 are aligned continuously at a position close to the reference line. Therefore, in the example shown in FIG. 5, the first inclined surface 26A1 corresponds to the reference line-proximate inclined surface.

[0086] As an example, in a cross section of the unit optical element 13 along the direction in which the inclined surfaces 26A are arranged, the standard deviation of the pitch of the reference line-proximate inclined surface on one side of the reference line is 5 μm or less and the standard deviation of the height is 1 μm or less. FIG. 5 corresponds to a cross section of the unit optical element 13 along the direction in which the inclined surfaces 26A are arranged. In the example shown in FIG. 5, the first inclined surface 26A1 corresponds to the reference line-proximate inclined surface. In this case, the standard deviation of the pitch P of the first inclined surface 26A1 on one side of the reference line (the right or left side of the first reference line L1 in FIG. 5) may be 5 μm or less and the standard deviation of the height H26 may be 1 μm or less. According to the decorative laminate 10 having such a unit optical element 13, a design expression with a three-dimensional effect that has not been seen before can be realized.

[0087] When 10 or more reference line-proximate tilting surfaces are arranged on one side of a reference line, the standard deviation of the pitch of the reference line-proximate tilting surfaces on one side of the reference line is the standard deviation of the pitch of the 10 tilting surfaces closest to the reference line on one side of the reference line in a cross section of the unit optical element 13 along the direction in which the plurality of tilting surfaces are arranged. When 10 or more reference line-proximate tilting surfaces are arranged on one side of a reference line, the standard deviation of the height of the reference line-proximate tilting surfaces on one side of the reference line is the standard deviation of the height of the 10 tilting surfaces closest to the reference line on one side of the reference line in a cross section of the unit optical element 13 along the direction in which the plurality of tilting surfaces are arranged.

[0088] In the example shown in FIG. 4, in the plan view of the decorative laminate 10, the uneven structure 25 has an inclined surface 26A that extends along at least a part of the outer contour 23a of the unit optical element 13. In the example shown in FIG. 4, the first inclined surface 26A1 extends along the outer contour 23a of the unit optical element 13. This makes it possible to effectively highlight the outer contour 23a of each unit optical element 13. In the example shown in FIG. 4, a gap region 24 is formed between adjacent unit optical elements 13. This also makes it possible to effectively highlight the outer contour 23a of each unit optical element 13. In the example shown in FIG. 4, the multiple unit optical elements 13 have a regular hexagonal outer contour 23a in plan view. In the example shown in FIG. 5, the multiple unit optical elements 13 form a honeycomb structure.

[0089] In the example shown in Fig. 5, the multiple first inclined surfaces 26A1 are aligned in a direction toward a first reference line L1 extending along the normal direction of the decorative laminate 10. The multiple first inclined surfaces 26A1 are inclined toward the first reference line L1. In the example shown in Fig. 4, the position of the first reference line L1 when the decorative laminate 10 is viewed in a plan view is fixed to one point. In the example shown in Fig. 4, the first reference line L1, which is the reference for the direction in which the multiple first inclined surfaces 26A1 are inclined in each unit optical element 13, coincides with the optical axis Ax of each unit optical element 13.

[0090] In the unit optical element 13 shown in Figures 4 and 5, the first region 234 spreads over the entirety of one of the unit optical elements 13. In other words, the unit optical element 13 shown in Figures 4 and 5 has the first region 234 and does not have a second region 235 described below. In the example shown in Figures 4 and 5, the concave-convex structure 25 in each unit optical element 13 has a Fresnel lens structure. The multiple first inclined surfaces 26A1 and the multiple first connecting surfaces 26B1 formed in the first region 234 of the unit optical element 13 shown in Figures 4 and 5 form the Fresnel lens structure.

[0091] When a plurality of unit optical elements 13 are regularly arranged in the region 20I as shown in FIG. 4, the geometric centers GC of the plurality of unit optical elements 13 in plan view may be regularly arranged in the region 20I. In this embodiment, the geometric center GC of the unit optical element 13 is the geometric center of the shape of the outer contour 23a of the unit optical element 13 observed from the normal direction of the decorative laminate 10. In this embodiment, the distance between the geometric centers GC of adjacent unit optical elements 13 in the region U is substantially uniform. In the example shown in FIG. 4, the optical axis Ax of each unit optical element 13 passes through the geometric center GC of each unit optical element 13 in plan view.

[0092] As described above, each unit optical element 13 of the present embodiment has an optical axis Ax. In this manner, when each unit optical element 13 has an optical axis Ax, the optical axes Ax of the multiple unit optical elements 13 may be regularly arranged in the region 20I. In this case, in the region 20I (hence, in the region U), the distance between the optical axes Ax of adjacent unit optical elements 13 is substantially uniform. In the example shown in FIG. 4, the optical axis Ax of each unit optical element 13 passes through the geometric center GC of each unit optical element 13 in a planar view. However, the position of the optical axis Ax of the unit optical element 13 is not limited to this. The optical axis Ax of each unit optical element 13 does not have to pass through the geometric center GC of the unit optical element 13 in a planar view.

[0093] In this embodiment, the decorative laminate 10 has a gap region 24 formed between a plurality of unit optical elements 13. In the illustrated example, the gap region 24 is formed between adjacent unit optical elements 13. More specifically, one side 23b of the outer contour 23a of the unit optical element 13 labeled with reference numeral 131 and one side 23b of the outer contour 23a of the unit optical element 13 labeled with reference numeral 132 are adjacent to each other with the gap region 24 sandwiched therebetween. The gap region 24 is formed between the sides 23b of the outer contour 23a of the unit optical element 13 labeled with reference numeral 131 and the unit optical element 13 labeled with reference numeral 132.

[0094] 4, in a plan view of the decorative laminate 10, the shape of each inclined surface 26A is similar to the shape of the outer contour 23a of the unit optical element 13. Each inclined surface 26A extends parallel to the outer contour 23a around the entire circumference of the outer contour 23a. This makes it possible to more effectively highlight the outer contour 23a of the unit optical element 13.

[0095] As an example, the concave-convex structure 25 in each unit optical element 13 is a linear Fresnel lens or has a structure in which linear Fresnel lenses are combined. In the example shown in Fig. 4, each inclined surface 26A in each unit optical element 13 includes a portion that extends linearly in parallel to any one of the sides 23b of the outer contour 23a of the unit optical element 13 between the optical axis Ax of the unit optical element 13 and the side 23b. This makes it possible to effectively highlight the outer contour 23a of the unit optical element 13.

[0096] Each unit optical element 13 can be appropriately designed according to the function required for the decorative laminate 10 or the design expressed by the decorative laminate 10. When the decorative member 3 is arranged facing the sensor 5 as in the illustrated example, the decorative laminate 10 is required to transmit the electromagnetic waves emitted from the sensor 5 through the decorative member 3 with high transmittance. In this case, it is preferable to reduce the thickness of the decorative laminate 10. The design expressed by the decorative laminate 10 may differ depending on the application of the decorative laminate 10. For example, when the decorative laminate 10 is used as an exterior material for the mobile body 1, it is preferable to suppress the occurrence of rainbow light on the front surface 11 of the decorative laminate 10. On the other hand, it may be preferable to design the decorative laminate 10 so that rainbow light occurs on its front surface 11.

[0097] When the thickness of the decorative laminate 10 is reduced while expressing a three-dimensional effect equal to or greater than the thickness of the decorative laminate 10, the height H25 of the uneven structure 25 is preferably 0.2 μm or more, more preferably 0.5 μm or more, and even more preferably 1 μm or more. The height H25 of the uneven structure 25 is preferably 50 μm or less, more preferably 25 μm or less, and even more preferably 10 μm or less. Therefore, the height H25 of the uneven structure 25 may be 1 μm or more and 50 μm or less. When the height H25 of the uneven structure 25 is 1 μm or more, the visibility of the design displayed by optical action can be further improved. In this specification, the "height H25 of the uneven structure" means the maximum value of the height (dimension in the Z direction Dz) H26 (see FIG. 5) of the inclined surface 26A or the connection surface 26B forming the uneven structure.

[0098] In order to prevent rainbow light from occurring on the front side surface 11 of the decorative laminate 10, the height H25 of the concave-convex structure 25 is preferably greater than 1.0 μm.

[0099] In order to suppress the occurrence of rainbow light on the front side surface 11 of the decorative laminate 10, the pitch P of the uneven structure 25 (also referred to as the pitch P of the inclined surface 26A) is preferably 7.5 μm or more, more preferably 12 μm or more, and even more preferably 15 μm or more. In addition, from the viewpoint of realizing a small size of the unit optical element 13, the pitch P of the uneven structure 25 is preferably 100 μm or less, more preferably 50 μm or less, and even more preferably 20 μm or less. Therefore, the pitch P of the uneven structure 25 is preferably 7.5 μm or more and 100 μm or less.

[0100] On the other hand, when it is desired to generate rainbow light on the front side surface 11 of the decorative laminate 10, the height H25 of the uneven structure 25 is preferably 0.1 μm or more, and more preferably 0.5 μm or more. In this case, the height H25 of the uneven structure 25 is preferably 1.0 μm or less. Therefore, the height H25 of the uneven structure 25 is preferably 0.1 μm or more and 1.0 μm or less.

[0101] When it is desired to generate rainbow light on the front side surface 11 of the decorative laminate 10, the pitch P of the uneven structure 25 is preferably less than 7.5 μm, more preferably 5 μm or less, and even more preferably 2 μm or less.

[0102] From the viewpoint of forming the concave-convex structure 25 with high accuracy, the height H25 of the concave-convex structure 25 is preferably 0.2 μm or more, more preferably 0.5 μm or more, and even more preferably 1.5 μm or more. From the same viewpoint, the pitch P of the concave-convex structure 25 is preferably 2 μm or more, more preferably 4 μm or more, and even more preferably 8 μm or more.

[0103] The pitches P of the concave-convex structures 25 may be equal to each other or different from each other. In the example shown in FIG. 4, the pitch P of the concave-convex structure 25 varies depending on the distance from the optical axis Ax of the concave-convex structure 25. Specifically, the pitch P becomes smaller as it moves away from the optical axis Ax. The height H25 of the concave-convex structure 25, the height H26 of the inclined surface 26A, and the pitch P can be measured by observing an image of a cross section of the decorative laminate 10 using a scanning electron microscope.

[0104] As described above, the concave-convex structure 25 of this embodiment is a Fresnel lens structure. The concave-convex structure 25 of this embodiment has a focal point. In this way, when the concave-convex structure 25 has a focal point, the focal length of the concave-convex structure 25 is preferably 0.5 mm or more and 350 mm or less. The focal length of the concave-convex structure 25 is more preferably 2 mm or more and 250 mm or less, and further preferably 5 mm or more and 150 mm or less. This makes it possible to effectively express a three-dimensional effect that is greater than the thickness of the mold layer 20 in the area where the unit optical elements 13 of the mold layer 20 are provided. This makes it possible to realize a rich design expression with a sense of luxury.

[0105] The focal length of the concave-convex structure 25 in at least one of the plurality of unit optical elements 13 may be different from the focal length of the concave-convex structure 25 in the other unit optical elements 13. This allows the viewer to perceive the positions of the unit optical elements 13 in the Z direction Dz as being different from one another. This makes it possible to realize a design expression with a three-dimensional effect that has not been seen before.

[0106] The rise angle θB (see FIG. 5) of the uneven structure 25 can be appropriately set. The connection surface 26B may extend in the Z direction Dz parallel to the normal direction (Z direction Dz) of the decorative laminate 10, or may extend non-parallel to the normal direction of the decorative laminate 10. In other words, the rise angle θB may be 0° or greater than 0°. Considering that the uneven structure 25 is made into a shape that is easy to shape and that the shaping surface 20a and other layers (in the illustrated example, the brightness adjustment layer 30) are more firmly attached to each other, the rise angle θB is preferably 15° or more, and more preferably 25° or more. From the viewpoint of ensuring a sufficient area of ​​the inclined surface 26A to allow the uneven structure 25 to appropriately exert the lens effect (in other words, from the viewpoint of allowing the shaping layer 20 to display an appropriate sense of depth), the rise angle θB is preferably 55° or less, and more preferably 45° or less.

[0107] In the illustrated example, a mixture of polymethyl methacrylate (PMMA) and urethane acrylate is used as the material constituting the shape-imparting layer 20. In the illustrated example, the material constituting the shape-imparting layer 20 contains silicone. Such a shape-imparting layer 20 can be formed by applying a liquid precursor material onto a substrate 72 or the like described below, shaping the precursor material with a shaping mold, and curing the shaping layer 20 by irradiating it with ultraviolet light. The precursor material of the shape-imparting layer 20 may be, for example, an ultraviolet-curable resin containing an acrylic resin and a (meth)acrylic polymerizable monomer or oligomer. The acrylic resin in this case may have a polymerizable unsaturated group. In this specification, the expression (meth)acrylic means one or both of "acrylic" and "methacrylic". The mass ratio of the acrylic resin / (meth)acrylic polymerizable monomer or oligomer is preferably 35 / 65 or more and 95 / 5 or less, and more preferably 70 / 30 or more and 90 / 10 or less. In this case, the acrylic resin / (meth)acrylic polymerizable monomer or oligomer may have a polymerizable unsaturated group in the ultraviolet curable resin. The shape-imparting layer 20 thus formed is flexible and extensible. Therefore, when the decorative laminate 10 is curved or stretched along the surface of the molding portion 65, the shape-imparting layer 20 can be curved or stretched as desired. In other words, there is little risk that the shape-imparting layer 20 will hinder the curving or stretching of the decorative laminate 10.

[0108] In the illustrated example, the mold layer 20 is transparent so that the brightness adjustment layer 30 can be seen from the front side surface 11. In the illustrated example, the concave-convex structures 25 of the multiple unit optical elements 13 are molded integrally without any seams (see FIG. 5). In the example shown in FIG. 5, the concave-convex structures 25 of the multiple unit optical elements 13 and the gap regions 24 located between the concave-convex structures 25 are molded integrally without any seams.

[0109] In the decorative laminate 10 of this embodiment, the surface displaying the object 90 in the object region 91 and the surface displaying the background in the background region 92 are formed by a single layer. In this embodiment, the surface of the brightness adjustment layer 30 facing the shaping surface 20a of the shaping layer 20 reflects light incident on the shaping layer 20 in the object region 91 and the background region 92. As a result, the object 90 is displayed in the object region 91, and the background is displayed in the background region 92. Therefore, the surface displaying the object 90 in the object region 91 and the surface displaying the background in the background region 92 are both the surfaces of the brightness adjustment layer 30 facing the shaping surface 20a of the shaping layer 20. As described above, the surface displaying the object 90 in the object region 91 and the surface displaying the background in the background region 92 are formed by the brightness adjustment layer 30, which is a single layer.

[0110] The above-mentioned mold layer 20 has unevenness that forms the uneven structure 25. In this embodiment, the mold layer 20 has unevenness that forms the uneven structure 25 in the background region 92. The unevenness that forms the uneven structure 25 is an intentionally formed unevenness. If unintended unevenness (e.g., steps or protrusions) is formed in the mold layer 20, unintended optical effects may be brought about, which may impair the appearance of the design displayed by the decorative laminate 10. In light of this point, the mold layer 20 of this embodiment is substantially free of unintended steps or protrusions. In the mold layer 20 of this embodiment, a plurality of unit optical elements 13 are formed in the same shape with high precision. In the mold layer 20 of this embodiment, a plurality of unit optical elements 13 are regularly arranged with high precision. In the mold layer 20 of this embodiment, the distance between the geometric centers GC of adjacent unit optical elements 13 is substantially uniform. Furthermore, in the shape-imparting layer 20 of the present embodiment, the distance between the optical axes Ax of adjacent unit optical elements 13 is substantially constant.

[0111] In FIG. 5, the range 20c occupied by the part located in the object region 91 of the shaping surface 20a in the normal direction (Z direction Dz) of the decorative laminate 10 is referred to as the object range 20c. In FIG. 5, the range 20d occupied by the part located in the background region 92 of the shaping surface 20a in the normal direction of the decorative laminate 10 is referred to as the background range 20d. Here, at least a part of the object range 20c in the normal direction of the decorative laminate 10 may overlap at least a part of the background range 20d. This makes it possible to make the range 20e occupied by the shaping surface 20a in the normal direction of the decorative laminate 10 smaller than when the object range 20c does not overlap the background range 20d. Therefore, the thickness of the shaping layer 20 having the shaping surface 20a can be reduced.

[0112] The entire object range 20c may be included in the background range 20d. In the example shown in FIG. 5, the unit shaping element 23 is not formed in the portion of the shaping surface 20a located in the object region 91. The portion of the shaping surface 20a located in the object region 91 is a flat surface perpendicular to the normal direction (Z direction Dz) of the decorative laminate 10. The portion of the shaping surface 20a located in the object region 91 is included in the background range 20d in the normal direction of the decorative laminate 10. As a result, the entire object range 20c is included in the background range 20d. The entire background range 20d may be included in the object range 20c. According to such a feature, the range 20e occupied by the shaping surface 20a in the normal direction of the decorative laminate 10 can be made smaller. Therefore, the thickness of the shaping layer 20 having the shaping surface 20a can be made smaller.

[0113] <Brightness adjustment layer> Next, the brightness adjustment layer 30 will be described. The brightness adjustment layer 30 is a layer that adjusts the brightness of the light reflected by the decorative laminate 10. By adjusting the brightness of the light reflected by the decorative laminate 10, it is possible to more effectively impart a rich design with a luxurious feel to the decorative laminate 10.

[0114] In the illustrated example, the brightness adjustment layer 30 is provided to adjust the reflectance of visible light measured on the front side surface 11 side of the decorative laminate 10. The brightness adjustment layer 30 covers the shaping surface 20a of the shaping layer 20. This adjusts the reflectance of visible light at the reflective interface 27 between the shaping surface 20a and the brightness adjustment layer 30, and adjusts the reflectance of visible light measured on the front side surface 11 side of the decorative laminate 10. The surface of the brightness adjustment layer 30 facing the shaping layer 20 has unevenness corresponding to the shaping surface 20a. In other words, the brightness adjustment layer 30 has an uneven structure corresponding to the uneven structure 25 of the shaping layer 20. In the example shown in FIG. 5, the brightness adjustment layer 30 also functions as a flattening layer that fills the unevenness of the shaping surface 20a.

[0115] In the illustrated example, the brightness adjustment layer 30 is a colored layer 30a colored with a pigment or dye. The colored layer 30a absorbs a part of the light incident on the decorative laminate 10, thereby adjusting the reflectance of visible light at the reflection interface 27 between the shaping surface 20a and the brightness adjustment layer 30. The colored layer 30a can impart a desired color to the decorative laminate 10. A material that is a mixture of a resin and a pigment or a dye can be used as a material for forming the colored layer 30a. The colored layer 30a may further contain additives such as an ultraviolet absorber and a light stabilizer.

[0116] The resin contained in the colored layer 30a may be, for example, a non-ultraviolet ray curable acrylic resin. The acrylic resin is, for example, a polymer of a (meth)acrylate compound. The polymer may be a homopolymer or a copolymer of a (meth)acrylate compound. Examples of the (meth)acrylate compound include alkyl (meth)acrylates such as methyl (meth)acrylate and ethyl (meth)acrylate, cycloalkyl (meth)acrylates such as cyclohexyl (meth)acrylate, aromatic (meth)acrylates such as phenyl (meth)acrylate, and hydroxyalkyl (meth)acrylates such as hydroxyethyl (meth)acrylate, hydroxypropyl (meth)acrylate, and hydroxybutyl (meth)acrylate. The acrylic resin is preferably polymethyl methacrylate (PMMA). In this specification, the expression "(meth)acrylate compound" means one or both of "acrylate compound" and "methacrylate compound".

[0117] The weight average molecular weight (Mw) of the acrylic resin may be, for example, 25,000 or more, or 50,000 or more, from the viewpoint of durability such as heat resistance and abrasion resistance. The Mw of the acrylic resin may be, for example, 100,000 or less, or 80,000 or less, from the viewpoint of interlayer adhesion. In this specification, Mw means a value measured by gel permeation chromatography using polystyrene as a standard substance, and is measured by a method in accordance with JIS K 7252-3:2016.

[0118] The glass transition temperature (Tg) of the acrylic resin may be, for example, 70° C. or higher, or 85° C. or higher, from the viewpoint of durability such as heat resistance and abrasion resistance. The Tg of the acrylic resin may be, for example, 110° C. or lower, or 100° C. or lower, from the viewpoint of interlayer adhesion. Therefore, the Tg of the acrylic resin may be 70° C. or higher and 110° C. or lower. In this specification, Tg is the glass transition temperature obtained by differential scanning calorimetry (DSC) in accordance with JIS K 7121:2012.

[0119] The resin contained in the colored layer 30a may be a cured product of an acrylic thermosetting resin. The cured product is formed, for example, from an acrylic thermosetting resin and a curing agent. An example of the acrylic thermosetting resin is an acrylic polyol having two or more hydroxyl groups in one molecule. An example of the acrylic polyol is a polymer of a (meth)acrylate compound using at least a hydroxyl group-containing monomer such as a hydroxyalkyl (meth)acrylate as a raw material monomer. An example of the curing agent is an isocyanate compound.

[0120] When the colored layer 30a is colored black, the colored layer 30a typically contains a black pigment. The colored layer 30a may contain a black dye instead of a black pigment, or may contain both a pigment and a dye. Examples of the black pigment contained in the colored layer 30a include carbon black, titanium black, composite metal oxides, and perylene black. Examples of the black dye contained in the colored layer 30a include an azo-based black dye and a nigrosine black dye.

[0121] When the colored layer 30a is colored blue, the colored layer 30a typically contains a blue pigment. The colored layer 30a may contain a blue dye instead of a blue pigment, or may contain both a pigment and a dye. As the blue pigment contained in the colored layer 30a, for example, a copper phthalocyanine pigment, an anthraquinone pigment, cobalt blue, or a composite metal oxide can be adopted. In addition, as the blue dye contained in the colored layer 30a, for example, a methine dye, an anthraquinone dye, an azo dye, a triarylmethane dye, or a phthalocyanine dye can be adopted.

[0122] When the colored layer 30a is colored red, the colored layer 30a typically contains a red pigment. The colored layer 30a may contain a red dye instead of a red pigment, or may contain both a pigment and a dye. As the red pigment contained in the colored layer 30a, for example, a diketopyrrolopyrrole pigment, an anthraquinone pigment, a quinacridone pigment, a perylene pigment, a composite metal oxide, or an iron oxide can be adopted. In addition, as the red dye contained in the colored layer 30a, for example, an azo dye, an anthraquinone dye, or a perinone dye can be adopted.

[0123] When the colored layer 30a is colored yellow, the colored layer 30a typically contains a yellow pigment. The colored layer 30a may contain a yellow dye instead of a yellow pigment, or may contain both a pigment and a dye. As the yellow pigment contained in the colored layer 30a, for example, isoindoline pigments, isoindolinone pigments, anthraquinone pigments, condensed azo pigments, composite metal oxides, and iron oxides can be adopted. In addition, as the yellow dye contained in the colored layer 30a, for example, azo dyes, anthraquinone dyes, methine dyes, quinophthalone dyes, and pyrazolone dyes can be adopted.

[0124] When the colored layer 30a is colored green, the colored layer 30a typically contains a green pigment. The colored layer 30a may contain a green dye instead of a green pigment, or may contain both a pigment and a dye. As the green pigment contained in the colored layer 30a, for example, a phthalocyanine pigment or an isoindoline pigment can be adopted. In addition, as the green dye contained in the colored layer 30a, for example, a triphenylmethane basic dye or a phthalocyanine dye can be adopted.

[0125] When the colored layer 30a is colored purple, the colored layer 30a typically contains a purple pigment. The colored layer 30a may contain a purple dye instead of the purple pigment, or may contain both a pigment and a dye. As the purple pigment contained in the colored layer 30a, for example, a quinacridone pigment or a dioxazine pigment can be adopted. Also, as the purple dye contained in the colored layer 30a, for example, an azo dye, an anthraquinone dye, an azine dye, or a quinoline dye can be adopted.

[0126] When the colored layer 30a is colored magenta, the colored layer 30a typically contains a magenta pigment. The colored layer 30a may contain a magenta dye instead of a magenta pigment, or may contain both a pigment and a dye. As the magenta pigment contained in the colored layer 30a, for example, a quinacridone pigment can be adopted. Also, as the magenta dye contained in the colored layer 30a, for example, a vermilion or an anthraquinone dye can be adopted.

[0127] The colored layer 30a may contain not only the pigments and dyes described above, but also a toning pigment or a toning dye. For example, when the colored layer 30a is colored black and the black pigment or black dye is reddish, the colored layer 30a may further contain the blue pigment or blue dye described above as a toning pigment or toning dye. In this case, various color pigments such as the above-mentioned red pigment, yellow pigment, green pigment, magenta pigment, and purple pigment can be used as the toning pigment in addition to the blue pigment. In this case, various dyes such as the above-mentioned red dye, green dye, magenta dye, yellow dye, and purple dye can be used as the toning dye in addition to the blue dye.

[0128] Alternatively, the colored layer 30a may be black by containing the above-mentioned pigments and dyes other than the black pigment and black dye.

[0129] Such a colored layer 30a is produced by applying a liquid precursor material to the shape-imparting surface 20a of the shape-imparting layer 20 and curing the liquid precursor material. The precursor material of the colored layer 30a contains the resin and the pigment or dye contained in the colored layer 30a described above.

[0130] When the luminance adjustment layer 30 is a colored layer 30a, the luminance adjustment layer 30 may be formed by, for example, solid printing of printing ink. Alternatively, as shown in FIG. 4 and FIG. 5, the luminance adjustment layer 30 may be configured to have a plurality of unit adjustment elements 41 that adjust the transmittance of visible light. In the example shown in FIG. 4, the plurality of unit adjustment elements 41 have the same shape in a plan view. The plurality of unit adjustment elements 41 are regular hexagonal in a plan view. The plurality of unit adjustment elements 41 are regularly arranged. In the example shown in FIG. 4, the plurality of unit adjustment elements 41 are arranged to form a honeycomb structure. In the example shown in FIG. 4, each unit adjustment element 41 has the same shape as the above-mentioned unit shaping element 23 in a plan view, and each unit adjustment element 41 is arranged so as to overlap the above-mentioned unit shaping element 23. However, this is not limited to this example. The plurality of unit shaping elements 23 may have different shapes from each other. The plurality of unit adjustment elements 41 may have a polygonal shape other than a hexagonal shape. The plurality of unit adjustment elements 41 may have a shape other than a polygonal shape. Each unit adjustment element 41 may have a shape different from the above-mentioned unit shaping element 23 in a plan view. Furthermore, although not shown, each unit adjustment element 41 may be arranged so as to overlap each other.

[0131] The total light transmittance of at least a part of the plurality of unit adjustment elements 41 may be different from the total light transmittance of the other unit adjustment elements 41. This allows the decorative laminate 10 to express a complex design.

[0132] The thickness of the colored layer 30a is preferably 0.1 μm or more and 500 μm or less.

[0133] <Joining layer> The bonding layer 38 bonds (adheses, sticks, or heat seals) other layers of the decorative laminate 10 and the molded portion 65. Thermoplastic resins, (meth)acrylic acid ester copolymers, and the like can be used as materials for forming the bonding layer 38. The thermoplastic resin is not particularly limited, and examples of the resin that can be used include acrylic resins, vinyl chloride-vinyl acetate copolymers, polyamide resins, polyester resins, chlorinated polypropylene, chlorinated rubber, urethane resins, epoxy resins, and styrene resins. These resins may be used alone or in combination of two or more.

[0134] <Functional layer> The functional layer 37 is a layer that is provided in expectation of various functions. Examples of the various functions include a hard coat function, a reflection suppression function, an anti-glare function, an anti-static function, and an anti-fouling function. In the illustrated example, the functional layer 37 is a peeling layer 37a. The peeling layer 37a has a peeling property that facilitates peeling of the decorative laminate 10 from the substrate 72 described later. As a material for forming the peeling layer 37a, for example, a thermoplastic resin such as an acrylic resin, a vinyl chloride-vinyl acetate resin, a polyurethane resin, a polyolefin resin, a polyester resin, an epoxy resin, or a silicone resin, or a thermosetting resin, an ultraviolet-curing resin, or an electron beam-curing resin that is a combination of these thermoplastic resins and a curing agent, can be used. In the illustrated example, the functional layer 37 forms the front side surface 11 of the decorative laminate 10. The other layers of the decorative laminate 10 are observed through the functional layer 37. Therefore, the functional layer 37 is transparent.

[0135] The thickness of the decorative laminate 10 having the above configuration may be 0.005 mm or more, 0.025 mm or more, 0.05 mm or more, 0.1 mm or more, or 0.15 mm or more. The thickness of the decorative laminate 10 may be 2 mm or less, 1.0 mm or less, 1 mm or less, 0.75 mm or less, or 0.5 mm or less. Therefore, the thickness of the decorative laminate 10 may be 0.005 mm or more and 2 mm or less.

[0136] The thickness of the decorative laminate 10 having the above configuration may be 0.005 mm or more and 2 mm or less, 0.025 mm or more and 1.0 mm or less, 0.05 mm or more and 1 mm or less, 0.1 mm or more and 0.75 mm or less, or 0.15 mm or more and 0.5 mm or less.

[0137] <<Function of Decorative Laminate>> Next, the action of the decorative laminate 10 will be described. The decorative laminate 10 displays a design and imparts the design to an article to which the decorative laminate 10 is applied. If the decorative laminate 10 can express a three-dimensional effect, a rich design expression with a sense of luxury is possible. The three-dimensional effect of the decorative laminate 10 can be expressed by forming a physical uneven structure. On the other hand, depending on the application of the decorative laminate 10, the thickness of the decorative laminate 10 may not be sufficiently thick. On the other hand, many decorative members, such as decorative members used in the front grille of a vehicle, may be required to be thin from the viewpoint of weight reduction. The thickness of a decorative member that is intended to transmit electromagnetic waves such as millimeter waves is set according to the wavelength of the millimeter waves and is subject to restrictions. In addition, it is preferable to reduce the thickness of the decorative laminate 10 from the viewpoint of improving the transmittance of electromagnetic waves.

[0138] In contrast, according to this embodiment, as shown in FIG. 5, the decorative laminate 10 has at least one unit optical element 13. FIG. 6 is a diagram for explaining the optical action of the mold layer 20. In this embodiment, the reflective interface 27 formed on the mold surface 20a of the mold layer 20 is configured to function as a convex mirror. In this case, as shown in FIG. 6, the range A1 reflected on the convex mirror M1 is wider than the specular reflecting surface arranged at the same position as the convex mirror M1. That is, the range A1 reflected on the convex mirror M1 is the same as the range A1 reflected on the specular reflecting surface M3 arranged farther away from the observer in the Z direction Dz. As a result, an observer who observes the reflection on the reflection interface 27 feels that the mold layer 20 functioning as the convex mirror M1 is located deeper than the actual position of the mold layer 20. That is, the mold layer 20 can display a design with a sense of depth that is deeper than the actual thickness of the mold layer 20. In this way, the shape-imparting layer 20 can display a design with a sense of depth greater than its thickness. Therefore, while making the shape-imparting layer 20 thin, it is possible to express a three-dimensional effect greater than the thickness of the shape-imparting layer 20. This allows for a rich design expression with a sense of luxury.

[0139] The decorative laminate 10 of this embodiment includes an object region 91 that displays an object 90, and a background region 92 located around the object region 91. In this embodiment, the decorative laminate 10 has a plurality of unit optical elements 13. The unit optical elements 13 are formed in at least a part of at least one of the background region 92 and the object region 91. This allows the observer to feel that the region of the reflection interface 27 in which the plurality of unit optical elements 13 are arranged is located deeper than the region in which the unit optical elements 13 are not arranged. In particular, in this embodiment, the plurality of unit optical elements 13 are provided in the background region 92. This allows the observer to feel that the object 90 stands out from the background region 92.

[0140] <<Method of manufacturing decorative laminate and decorative member>> Next, a manufacturing method of the decorative laminate 10 and the decorative member 3 according to the present embodiment will be described with reference to Fig. 7A to Fig. 10E. The manufacturing method of the decorative laminate 10 includes a step of producing a master mold 110, a step of forming a shaping mold 100, and a step of shaping the shaping layer 20.

[0141] First, a method for producing a matrix 110 for forming the shaping mold 100 will be described with reference to Figs. 7A to 7C. In the process of producing the matrix 110, a laser beam is irradiated at each position on the photosensitive layer 113 with an exposure amount corresponding to the shape of the shaping surface 20a of at least one unit optical element 13 of the shaping layer 20 described above. As a result, a matrix 110 having an uneven surface 110a corresponding to the shape of the shaping surface 20a of at least one unit optical element 13 is produced from the photosensitive layer 113. The decorative laminate 10 of this embodiment has a plurality of unit optical elements 13. In this case, a matrix 110 having an uneven surface 110a corresponding to the shape of the shaping surface 20a of the plurality of unit optical elements 13 is produced from the photosensitive layer 113. In this embodiment, a matrix 110 having an uneven surface 110a corresponding to the shape in the region 20I of the shaping surface 20a is produced from the photosensitive layer 113.

[0142] In the process of producing the matrix 110, first, a matrix forming member 111 is prepared as shown in Fig. 7A. The matrix forming member 111 includes a flat substrate 112 such as a glass plate, and a photosensitive material layer 113 that covers one surface of the substrate 112. In the illustrated example, the photosensitive material layer 113 is formed using a positive resist.

[0143] Next, as shown in FIG. 7B, the photosensitive layer 113 is irradiated with laser light R. At this time, the entire area of ​​the photosensitive layer 113 is irradiated with the laser light R while moving the irradiation position of the laser light R on the mold forming member 111. At this time, the intensity of the laser light R is controlled in multiple gradations of three or more gradations. The intensity of the laser light R is controlled based on data representing the uneven structure 25. This data includes information on the uneven pattern to be formed on the shaping surface 20a of the shaping layer 20. This uneven pattern is an uneven pattern of an area including a plurality of unit shaping elements 23 of the shaping layer 20 (and therefore includes the shape of the shaping surface 20a in the gap area 24 between these plurality of unit optical elements 13). In this embodiment, this uneven pattern is an uneven pattern of an area of ​​the shaping surface 20a of the shaping layer 20 that spans the object area 91 and the background area 92. In this embodiment, this uneven pattern is an uneven pattern in the region 20I of the shaping surface 20a of the shaping layer 20. This uneven pattern expresses the height (depth) of the unevenness to be formed on the shaping surface 20a with reference to the non-shaping surface 20b in multiple steps of three or more. Using such data, the intensity of the laser light R is controlled in multiple tones of three or more gradations. In addition, the laser light R is irradiated to each position on the photosensitive layer 113 with an intensity that reflects the uneven pattern. As a result, the exposure amount of the laser light R at each position on the photosensitive layer 113 reflects the uneven pattern.

[0144] Next, as shown in Fig. 7C, the photosensitive layer 113 is developed to remove a part of the photosensitive layer 113. As described above, the exposure amount of the laser light R at each position of the photosensitive layer 113 is an exposure amount that reflects the above-mentioned uneven pattern, so that unevenness that reflects the above-mentioned uneven pattern is formed in the photosensitive layer 113 after development. In this way, a master mold 110 having an uneven surface 110a corresponding to the shape of the region 20I of the shape-imparting surface 20a of the shape-imparting layer 20 is produced from the photosensitive layer 113.

[0145] In this way, the master mold 110 having projections and recesses corresponding to the plurality of projection-recess structures 25 of the plurality of unit shaping elements 23 is formed integrally and seamlessly. This reduces the risk of unintended projections and recesses being formed on the master mold 110. In addition, by adjusting the exposure amount of the laser light R of the photosensitive material layer 113 in multiple gradations, projections and recesses corresponding to the projection-recess pattern can be formed on the master mold 110 with high precision.

[0146] In this embodiment, the laser light is irradiated to each position on the photosensitive layer 113 with an exposure amount corresponding to the shape of the shaping surface 20a of the above-mentioned shaping layer 20. In this way, the photosensitive layer 113 is used to produce a master mold 110 having an uneven surface 110a corresponding to the shape of the shaping surface 20a.

[0147] Next, the process of forming the shaping mold 100 will be described with reference to Figures 8A and 8B. In the process of forming the shaping mold 100, the shaping mold 100 is formed on the uneven surface 110a of the mother mold 110. In the process of forming the shaping mold 100, first, as shown in Figure 8A, a metal layer 115 is formed on the uneven surface 110a of the mother mold 110. The metal layer 115 may be formed of nickel or the like by, for example, electroforming. In the metal layer 115, unevenness is formed that reflects the unevenness of the mother mold 110 (thus, reflecting the above-mentioned uneven pattern).

[0148] Next, as shown in Fig. 8B, the metal layer 115 is separated from the matrix 110. The metal layer 115 may be separated from the matrix 110, for example, by dissolving and removing the photosensitive material layer 113 of the matrix 110 with a solvent. The metal layer 115 separated from the matrix 110 is used as the shaping mold 100. In this manner, the shaping mold 100 capable of shaping the region 20I shown in Fig. 3 at once can be formed.

[0149] As shown in FIG. 9, by using the shaping mold 100 thus produced, a plurality of unit shaping elements 23 can be shaped at once in the intended arrangement pattern in the portion located in the region 20I of the shaping layer 20. Therefore, a plurality of unit shaping elements 23 can be formed in the shaping layer 20 with high precision in the intended planar shape and arrangement pattern. At the same time, the shape of the shaping surface 20a in the gap region 24 between the plurality of unit optical elements 13 can also be shaped. Therefore, the gap region 24 can be formed with high precision with the intended width W24 (see FIG. 4). Furthermore, by using the shaping mold 100 thus produced, a shaping surface 20a having a desired shape in each of the object region 91 and the background region 92 can be formed in the shaping layer 20.

[0150] The effects of the process of preparing the matrix 110 and the process of forming the shaping mold 100 in the manufacturing method of the decorative laminate 10 of this embodiment will be described in more detail by comparison with the conventional technology. First, with reference to Figs. 52A to 52C, a method of preparing a shaping mold for forming a conventional uneven structure 25 will be described. Conventional shaping molds have been prepared using a matrix 310 formed as follows. First, the surface of a plate-shaped matrix piece forming member is cut using a diamond cutting tool to form unevenness corresponding to the uneven structure 25 of the unit shaping element. Next, a matrix piece 320 including an uneven structure is manually cut out from the matrix piece forming member. One matrix piece 320 corresponds to one unit shaping element 23 of the shaping layer 20. A plurality of matrix pieces 320 prepared in this manner are arranged in a frame 330 to form one matrix 310. Next, an electroforming process is performed on the uneven surface of the formed matrix 310 to form a metal layer that becomes the shaping mold. Thereafter, the metal layer is removed from the matrix 310. The shaping mold thus formed has projections and recesses that reflect the projections and recesses formed on each of the master mold pieces 320 .

[0151] However, it is difficult to accurately cut out the mold pieces 320 from the mold piece forming member with the intended dimensions and shape. For this reason, the mold pieces 320 are generally cut out to be slightly larger than the intended dimensions so that no gaps will be generated when the mold pieces 320 are laid out in the frame 330. When such mold pieces 320 are laid out in the frame 330, it may not be possible to arrange the multiple mold pieces 320 as intended. For example, as shown in FIG. 52A, when arranging the mold pieces 320, the edges of the adjacent mold pieces 320 may overlap, and an unintended step 310S may be formed in the mold 310 formed by the mold pieces 320. Alternatively, as shown in FIG. 52B, some of the multiple mold pieces 320 may not be arranged on the same plane as the other mold pieces 320, and some of the mold pieces 320 may rise up from the other mold pieces 320. In this case, an unintended protuberance 310T may be formed in a part of the mold 310. Such steps 310S and protuberances 310T of the matrix 310 are reflected in the shaping mold formed using the matrix 310. As a result, unintended steps and protuberances are formed in the shaping layer 20 shaped by the shaping mold. The steps and protuberances thus formed in the shaping layer 20 are observed as streaks extending between adjacent unit shaping elements 23, or may bring about unintended optical effects.

[0152] Furthermore, if the shape of the matrix piece in plan view is different from the intended shape, the multiple matrix pieces cannot be arranged as intended. As a result, as shown in FIG. 52C, a matrix 310 is formed in which the shape and arrangement of the matrix pieces 320 are less regular, and as a result, a shaping layer 20 is formed in which the shape and arrangement of the multiple unit shaping elements 23 are less regular. Furthermore, since the matrix pieces 320 are manually cut out from the matrix piece forming member, the edges of the matrix pieces 320 are not smooth. As a result, it is difficult to form a unit optical element whose outer contour includes straight sides.

[0153] Further, the decorative laminate 10 of the present embodiment includes an object region 91 and a background region 92. The unit optical elements 13 are formed on the shaping surface 20a of the shaping layer 20 in at least a part of at least one of the background region 92 and the object region 91. It is difficult to manufacture the shaping layer 20 having such a complex shape of the shaping surface 20a by the conventional method of forming the matrix 310 by cutting. In particular, in the decorative laminate 10 of the present embodiment, the object region 91 divides the background region 92 into a plurality of regions. In particular, in the decorative laminate 10 of the present embodiment, the unit optical elements 13 are formed in each of the plurality of regions formed by dividing the background region 92 by the object region 91. The shape of the shaping surface 20a of the shaping layer 20 of such a decorative laminate 10 becomes more complex. It is particularly difficult to manufacture the shaping layer 20 having such a shape of the shaping surface 20a by the method of forming the matrix 310 by cutting. In the decorative laminate 10 of this embodiment, the unit optical element 13 adjacent to the boundary 93 has a shape in which a part of the unit optical element 13 located at a position away from the boundary 93 is cut out at a virtual plane. The unit optical element 13 adjacent to the boundary 93 is arranged in the background region 92 so that the virtual plane overlaps the boundary 93. It is particularly difficult to produce a shaping layer 20 having a shaping surface 20a of such a shape by a method of forming a master mold 310 by cutting.

[0154] In contrast, in the manufacturing method of the decorative laminate 10 of the present embodiment, the shaping mold 100 is manufactured using the matrix 110 which is less likely to have unintended unevenness. Therefore, there is less risk of unintended unevenness being formed on the shaping mold 100. Therefore, there is less risk of the shaping mold 100 forming unintended unevenness on the shaping layer 20.

[0155] Furthermore, the matrix 110 produced in the method for producing the decorative laminate 10 of the present embodiment has a higher degree of freedom in designing the concave-convex structure 25 than the conventional method of producing the matrix 310 by cutting. Specifically, the shape of the inclined surface 26A and the connecting surface 26B in plan view can be set more freely than in the conventional method. For example, the shape of the inclined surface 26A and the connecting surface 26B in plan view can be a polygonal shape such as a hexagonal shape as shown in FIG. 4. Alternatively, the shape of the inclined surface 26A and the connecting surface 26B in plan view can be a shape including a curved portion or a portion extending in an arc shape. Furthermore, it is easy to make the width W24 of the gap region 24 between adjacent unit optical elements 13 constant, as shown in FIG. 4.

[0156] Further, the decorative laminate 10 of this embodiment includes an object region 91 and a background region 92. The unit optical element 13 is formed on the shaping surface 20a of the shaping layer 20 in at least a part of at least one of the background region 92 and the object region 91. As described above, it is difficult to manufacture the shaping layer 20 having such a complex shape of the shaping surface 20a by the conventional method of forming the matrix 310 by cutting. In particular, in the decorative laminate 10 of this embodiment, the object region 91 divides the background region 92 into a plurality of regions. In particular, in the decorative laminate 10 of this embodiment, the unit optical element 13 is formed in each of the plurality of regions formed by dividing the background region 92 by the object region 91. In the decorative laminate 10 of this embodiment, the unit optical element 13 adjacent to the boundary 93 has a shape in which a part of the unit optical element 13 located at a position away from the boundary 93 is cut off by a virtual plane. The unit optical element 13 adjacent to the boundary 93 is arranged in the background region 92 so that the virtual surface overlaps the boundary 93. As described above, it is particularly difficult to produce such a shaping layer 20 by the conventional method of forming a matrix 310 by cutting. According to the process of producing the matrix 110 and the process of forming the shaping mold 100 of this embodiment, it is possible to form the shaping mold 100 capable of forming the shaping surface 20a of such a complex shape. Therefore, the manufacturing method of the decorative laminate 10 of this embodiment is a manufacturing method more suitable for manufacturing the decorative laminate 10 of this embodiment than the method of forming the matrix 310 by cutting.

[0157] Next, the process of producing the shape-imparting layer 20 will be described with reference to Figs. 10A to 10E. Figs. 10A to 10E are cross-sectional views showing a method of producing a transfer sheet 70 for transferring the decorative laminate 10 to a molding portion 65. As an example, the shape-imparting layer 20 is produced in the process of producing the transfer sheet 70. The process of producing the shape-imparting layer 20 includes a process of shaping the shaping surface 20a of the shape-imparting layer 20 using a shaping mold 100. In this way, the shape-imparting layer 20 having at least one unit shaping element 23 is produced.

[0158] First, as shown in FIG. 10A, a flat substrate 72 is prepared. The substrate 72 is a member that is peeled off from the decorative laminate 10 when the decorative laminate 10 is transferred to the molding portion 65. That is, the substrate 72 is a transfer substrate. As the substrate 72, for example, a polyester resin film or a polyolefin resin film, which is used as a substrate for a general transfer sheet, can be adopted. A release layer may be formed on one surface of the substrate 72. The release layer has a releasability that facilitates the peeling off of the substrate 72 from the decorative laminate 10. As a material for forming the release layer, for example, a thermoplastic resin such as an acrylic resin, a vinyl chloride-vinyl acetate resin, a polyurethane resin, a polyolefin resin, a polyester resin, an epoxy resin, or a silicone resin, or a thermosetting resin that combines these thermoplastic resins with a curing agent can be adopted. Instead of forming a release layer on the substrate 72, a known release treatment may be applied to the surface of the substrate 72. In this case, the substrate 72 can also be easily peeled off from the decorative laminate 10.

[0159] Next, the release layer 37a is formed on the substrate 72. When a release layer is formed on the substrate 72, the release layer 37a is formed on the release layer. By forming the release layer 37a on the substrate 72, the substrate 72 can be easily peeled off from the decorative laminate 10.

[0160] Next, as shown in FIG. 10B, a layer 29 of the precursor material of the above-mentioned mold layer 20 is formed on the peeling layer 37a. Next, as shown in FIG. 10C, a mold 100 is pressed against the layer 29 to mold it. The mold 100 has irregularities corresponding to the irregular structure 25. Next, the layer 29 is irradiated with ultraviolet light to harden it. This produces a mold layer 20 in which the irregular structure 25 is formed on the mold surface 20a. The mold 100 is then removed from the mold layer 20. The mold 100 may be removed from the layer 29 before the layer 29 is irradiated with ultraviolet light.

[0161] The unevenness of the shaping mold 100 is determined so that the rise angle θB of the uneven structure 25 is not 0° but 15° or more. This makes it easy to form unevenness that reflects the unevenness of the shaping mold 100 with high accuracy in the layer 29 when the layer 29 is shaped by the shaping mold 100. In other words, it is easy to form the uneven structure 25 in the shaping layer 20 according to the unevenness of the shaping mold 100. In addition, since the rise angle θB of the uneven structure 25 is 15° or more, it is easy to remove the shaping layer 20 or the layer 29 from the shaping mold 100. As a result, the shaping layer 20 having at least one unit shaping element 23 can be produced.

[0162] Next, as shown in FIG. 10D, a colored layer 30a is formed on the shaping surface 20a of the shaping layer 20. The colored layer 30a is formed by applying a precursor material, which is a mixture of a resin and a pigment or a dye, to the shaping surface 20a. When the resin contained in the precursor material of the colored layer 30a is a thermoplastic resin, the precursor material is applied to the shaping surface 20a and then dried to form the colored layer 30a. When the resin contained in the precursor material of the colored layer 30a is a thermosetting resin, the precursor material may be applied to the shaping surface 20a, dried and heated, or dried and placed in a room temperature or high temperature environment for a certain period of time, to harden the colored layer 30a. After hardening the colored layer 30a, a bonding layer 38 is formed on the colored layer 30a, as shown in FIG. 10E. This produces the transfer sheet 70 shown in FIG. 10E. In other words, the decorative laminate 10 is manufactured on the substrate 72. The transfer sheet 70 shown in FIG. 10E includes a transfer substrate (substrate 72) and the decorative laminate 10.

[0163] Next, the transfer sheet 70 is placed in a mold for forming the molded portion 65. Next, molten resin is introduced between the back side surface 12 (i.e., the bonding layer 38) on the decorative laminate 10 and the inner surface of the mold, and the resin is solidified in the mold. As a result, the molded portion 65 bonded to the transfer sheet 70 is molded in the mold. Thereafter, the substrate 72 is peeled off from the decorative laminate 10. As a result, the decorative member 3 (see FIG. 2A) in which the decorative laminate 10 is transferred to the molded portion 65 is completed. Such a molding method for the decorative member 3 is known as in-mold molding.

[0164] <<Modifications>> Next, various modified examples of this embodiment will be described with reference to Figures 2B to 2N and Figures 11 to 51. In Figures 2B to 2N and Figures 11 to 51, the same parts as those shown in Figures 1A, 1B, 2A, and 3 to 10E are denoted by the same reference numerals, and detailed description thereof will be omitted.

[0165] <Modification 1: Modification of Decorative Laminate and Decorative Member> <Modifications of Unit Optical Elements> In the above-mentioned specific example, the unit optical element 13 is configured to function as a convex lens, but the present invention is not limited to this example. In the example shown in FIG. 11, the unit optical element 13 is configured to function as a concave lens. In the example shown in FIG. 11, the concave-convex structure 25 in the unit optical element 13 is a Fresnel lens structure. The central part of the concave-convex structure 25 in the unit optical element 13 forms a curved surface recessed from the front side surface 11 toward the back side surface 12 in the Z direction Dz. Therefore, when the decorative laminate 10 is observed from the front side surface 11 side, the reflection interface 27 formed on the shaping surface 20a functions as a concave mirror. In this case, the inclined surface 26A of the shaping surface 20a may be configured to have a shape formed by dividing a continuous concave lens surface.

[0166] When the concave-convex structure 25 is configured to function as a concave lens and has a focal point, the focal length of the concave-convex structure 25 is preferably -350 mm or more and -0.5 mm or less. The focal length of the concave-convex structure 25 is more preferably -250 mm or more and -2 mm or less, and even more preferably -150 mm or more and -5 mm or less. By having the focal length of the concave-convex structure 25 be -350 mm or more and -0.5 mm or less, a three-dimensional effect greater than the thickness of the mold-imparting layer 20 can be effectively expressed. This allows for a rich design expression with a luxurious feel to be realized.

[0167] According to the decorative laminate 10 shown in FIG. 11, as shown in FIG. 12, the range A2 reflected on the concave mirror M2 is narrower than the range A2 reflected on the mirror reflecting surface arranged at the same position as the concave mirror M2. That is, the range A2 reflected on the concave mirror M2 is the same as the range A2 reflected on the mirror reflecting surface M4 arranged closer to the observer in the Z direction Dz. As a result, the observer who observes the reflection on the unit optical element 13 feels that the unit optical element 13 functioning as the concave mirror M2 is located in front of the actual position of the mold-imparting layer 20. Therefore, even in this case, a design with a sense of depth can be displayed compared to the actual thickness of the mold-imparting layer 20. This allows for a three-dimensional design expression that has not been seen before.

[0168] <Modifications of the brightness adjusting layer shown in Figs. 13A and 13B> In the above-mentioned specific example, the brightness adjustment layer 30 is a colored layer 30a, but the present invention is not limited to this example. As shown in Fig. 13A, the brightness adjustment layer 30 may be a reflective layer 30b. In the example shown in Fig. 13A, the shaping surface 20a is covered with a single covering layer, that is, a reflective layer 30b, in the object region 91 and the background region 92.

[0169] The reflective layer 30b covers the shaping surface 20a of the shaping layer 20 to form a reflective interface 27 between the shaping surface 20a and the reflective layer 30b. The reflective layer 30b improves the reflectance of visible light at the reflective interface 27 between the shaping surface 20a and the reflective layer 30b, thereby adjusting the brightness of the light reflected by the decorative laminate 10. The reflective layer 30b can be formed by deposition of a metal material or an inorganic material, or coating of a metal material or an inorganic material. The reflective layer 30b may be a transparent deposition layer. The reflective layer 30b is formed as a thin film-like layer. The thickness of the reflective layer 30b may be thinner than the height H26 of the connection surface 26B. The thickness of the reflective layer 30b may be half or less of the height H25 of the uneven structure 25, 25% or less of the height H26 of the connection surface 26B, or 10% or less of the height H26 of the connection surface 26B. The reflective layer 30b having such a thickness does not fill the unevenness of the shaping surface 20a, but has unevenness corresponding to the unevenness of the shaping surface 20a on the side opposite to the side facing the shaping surface 20a. Although not shown, the reflective layer 30b may fill the unevenness of the shaping surface 20a. As an example, when the decorative laminate 10 has the reflective layer 30b and the shaping layer 20 is transparent, the reflective interface 27 formed between the shaping surface 20a and the reflective layer 30b is visible from the front side surface 11.

[0170] In the example shown in FIG. 13A, the brightness adjustment layer 30 (reflective layer 30b) has unevenness corresponding to the unevenness of the shaping surface 20a on the side opposite to the side facing the shaping surface 20a. The unevenness of the brightness adjustment layer 30 is filled by the bonding layer 38. Although not shown, similar to the example of the colored layer 30a shown in FIG. 5, the reflective layer 30b may be formed so as to fill the unevenness of the shaping surface 20a. In the example shown in FIG. 13A, the surface of the reflective layer 30b facing the bonding layer 38 has unevenness corresponding to the unevenness of the Fresnel lens surface 26. Therefore, the bonding layer 38 has unevenness corresponding to the unevenness of the Fresnel lens surface 26.

[0171] As the material of the reflective layer 30b, it is preferable to use a material that improves the reflectance of the reflective interface 27 formed by the reflective layer 30b, and more preferably to use a material that has radio wave transparency. In this case, as the material constituting the reflective layer 30b, for example, a metal material such as aluminum, indium, tin, zinc oxide (ZnO), titanium oxide (TiO2), zinc sulfide, aluminum oxide, etc. can be used. In particular, when the decorative laminate 10 is joined to the molded part 65 by insert molding, it is preferable that the material constituting the reflective layer 30b is a metal material such as indium, tin, zinc oxide (ZnO), titanium oxide (TiO2), zinc sulfide, aluminum oxide, etc.

[0172] As described above, the electromagnetic waves used in the sensor 5 are transmitted through the decorative laminate 10. When the reflective layer 30b is formed as a layer that continuously spreads over the entire surface of the shaping surface 20a, the electromagnetic waves are blocked or attenuated. Therefore, as shown in FIG. 13B, the reflective layer 30b may include a plurality of metal grain portions 31. The metal grain portions 31 have a metallic luster and are capable of reflecting visible light. The reflective layer 30b forms islands in a so-called sea-island structure. The island-like metal grain portions 31 are spaced apart from each other. Between the plurality of metal grain portions 31, there are provided gaps that form the sea of ​​the sea-island structure. The electromagnetic waves used in the sensor 5, for example, millimeter waves, are transmitted through the reflective layer 30b by passing through the gaps. Such a metal layer can be formed by deposition such as sputtering or vacuum deposition using, for example, an indium material. The reflective layer 30b may be formed seamlessly and integrally across a plurality of unit optical elements 13.

[0173] The thickness of the reflective layer 30b is preferably a thickness that can improve the reflectance of the reflective interface 27 formed by the reflective layer 30b. The thickness of the reflective layer 30b may be, for example, 0.005 μm or more. The thickness of the reflective layer 30b may be 20 μm or less. Therefore, the thickness of the reflective layer 30b may be 0.005 μm or more and 20 μm or less. The thicknesses of the reflective layer 30b and other layers included in the decorative laminate 10 can also be measured by observing an image of a cross section of the decorative laminate 10 using a scanning electron microscope.

[0174] The decorative laminate 10 including the reflective layer 30b can be manufactured by a manufacturing method for the decorative laminate 10 including a step of forming the reflective layer 30b on the shaping surface 20a of the shaping layer 20. In this case, in the step of forming the reflective layer 30b, the reflective layer 30b is formed on the shaping surface 20a by a film forming technique such as sputtering or vacuum deposition.

[0175] <Modification of the brightness adjustment layer shown in FIG. 14A> Although the example in which the brightness adjustment layer 30 is the reflective layer 30b has been described above, the form of the decorative laminate 10 is not limited to this example. As shown in FIG. 14A, the brightness adjustment layer 30 may be a refractive index modulation layer 30c. In the example shown in FIG. 14A, the shaping surface 20a is covered with the refractive index modulation layer 30c, which is a single covering layer, in the object region 91 and the background region 92. The refractive index modulation layer 30c is a layer whose refractive index is different from that of the shaping layer 20. When the concave-convex structure 25 of the shaping layer 20 is covered with the refractive index modulation layer 30c, a reflective interface 27 is formed between the shaping layer 20 and the refractive index modulation layer 30c, and the reflectance of light on the shaping surface 20a can be improved. This adjusts the brightness of the light reflected by the decorative laminate 10.

[0176] The refractive index modulation layer 30c can be formed by deposition or coating of a high refractive index material (for example, a metal oxide, a metal sulfide, or a metal nitride). The refractive index modulation layer 30c may be a transparent deposition layer. As the high refractive index material forming the refractive index modulation layer 30c, any one of titanium oxide, zirconium oxide, aluminum oxide, zinc oxide, zinc sulfide, barium titanate, or a combination of these can be used. The refractive index modulation layer 30c may also be a transparent deposition layer. By forming the refractive index modulation layer 30c from such a material, the electromagnetic wave transmittance of the refractive index modulation layer 30c can be improved.

[0177] When the refractive index modulation layer 30c is formed by coating a high refractive index material, the refractive index modulation layer 30c can be formed, for example, by the following method. That is, an ink containing high refractive index particles with an average particle diameter of 100 nm or less formed of a high refractive index material is prepared, and this is coated on the shaping surface 20a. In this way, the refractive index modulation layer 30c can be formed. For example, a zirconium oxide dispersion (SZR series (product name) manufactured by Sakai Chemical Industry Co., Ltd.) can be used as the ink containing such high refractive index particles. The ink may or may not contain a binder resin. For the binder resin, an ultraviolet curable resin, an ionizing radiation curable resin, or the like can be used. The ionizing radiation curable resin is, for example, an electron beam curable resin. The refractive index modulation layer 30c containing an ultraviolet curable resin or an electron beam curable resin as a binder resin is flexible and has extensibility. Therefore, when the decorative laminate 10 is curved or stretched along the surface of the molding portion 65, the refractive index modulation layer 30c can be curved or stretched as desired. In other words, there is little risk that the refractive index modulation layer 30c will hinder the curvature or stretching of the decorative laminate 10.

[0178] In a modification in which the luminance adjustment layer 30 is the refractive index modulation layer 30c, for example, the rise angle θB of the concave-convex structure 25 is not 0° but is 15° or more. This makes it easy to form the refractive index modulation layer 30c on the connection surface 26B.

[0179] The refractive index modulation layer 30c may be formed as a thin film-like layer, similar to the reflective layer 30b shown in FIG. 13A. In this case, the thickness of the refractive index modulation layer 30c may be thinner than the height H26 of the connecting surface 26B. The thickness of the refractive index modulation layer 30c may be half or less of the height H26 of the connecting surface 26B, 25% or less of the height H26 of the connecting surface 26B, or 10% or less of the height H26 of the connecting surface 26B. The refractive index modulation layer 30c having such a thickness does not fill the unevenness of the shaping surface 20a, but has unevenness corresponding to the unevenness of the shaping surface 20a on the side opposite to the side facing the shaping surface 20a.

[0180] Alternatively, the refractive index modulation layer 30c may be formed so as to fill in the irregularities of the shaping surface 20a, similar to the example shown in FIG.

[0181] The thickness of the refractive index modulation layer 30c is preferably a thickness that can improve the reflectance of the reflection interface 27 formed by the refractive index modulation layer 30c. The thickness of the refractive index modulation layer 30c may be, for example, 0.005 μm or more. The thickness of the refractive index modulation layer 30c may be 20 μm or less.

[0182] <Modification of the Reflective Interface> In the above-mentioned specific example, the luminance adjustment layer 30 forms a reflective interface 27 with the shape-imparting layer 20, but is not limited thereto. Whether the luminance adjustment layer 30 is the colored layer 30a, the reflective layer 30b, or the refractive index modulation layer 30c, the luminance adjustment layer 30 may form a reflective interface 27 with a layer (for example, the bonding layer 38 in FIG. 13A) facing the surface 33 opposite to the surface 32 facing the shape-imparting layer 20. In this case, as shown in FIG. 13A, if the luminance adjustment layer 30 has unevenness on the opposite surface 33 corresponding to the unevenness of the shape-imparting surface 20a, the reflective interface 27 on the opposite surface 33 will have a shape corresponding to the unevenness of the shape-imparting surface 20a. Therefore, the reflective interface 27 on the opposite surface 33 provides an optical effect corresponding to the uneven structure 25 of the shape-imparting layer 20 to the light incident on the unit optical element 13. In this case as well, the brightness adjusting layer 30 adjusts the reflectance of visible light at the reflective interface 27, and the reflectance of visible light measured on the front surface 11 side of the decorative laminate 10 is adjusted.

[0183] Therefore, when the brightness adjustment layer 30 is a refractive index modulation layer 30c and has unevenness corresponding to the unevenness of the shaping surface 20a on the opposite surface 33, the refractive index modulation layer 30c may form a reflection interface 27 with a layer facing the opposite surface 33 (the bonding layer 38 in the example shown in FIG. 14A). In this case, the refractive index of the refractive index modulation layer 30c may be different from the refractive index of the layer facing the opposite surface 33 (the bonding layer 38 in the example shown in FIG. 14A). In this case, the reflection interface 27 may not be formed between the refractive index modulation layer 30c and the shaping layer 20. More specifically, the refractive index of the refractive index modulation layer 30c may be the same as the refractive index of the shaping layer 20.

[0184] When the luminance adjusting layer 30 has unevenness on the opposite surface 33 that corresponds to the unevenness of the shaping surface 20 a , the reflective interfaces 27 may be formed on both sides of the luminance adjusting layer 30 .

[0185] <Decorative laminate and decorative member shown in Fig. 2B and Fig. 2C> When the brightness adjustment layer 30 is the reflective layer 30b or the refractive index modulation layer 30c, the decorative laminate 10 may further have a colored layer 45. This allows the decorative laminate 10 to be colored to a desired color. In addition, the brightness of the reflected light in the decorative laminate 10 can be adjusted not only by the brightness adjustment layer 30 but also by the colored layer 45. In the example shown in FIG. 2B and FIG. 14B, the colored layer 45 is disposed closer to the back surface 12 of the decorative laminate 10 than the shape-imparting layer 20 and the brightness adjustment layer 30. In FIG. 14B and FIG. 14C to FIG. 14K described later, a portion of the decorative laminate 10 where the unit shape-imparting element 23 and the gap region 24 are formed is shown in an enlarged manner. In the example shown in FIG. 2B and FIG. 14B, more specifically, the bonding layer 38, the colored layer 45, the brightness adjustment layer 30, the shape-imparting layer 20, and the functional layer 37 are laminated in this order in the direction from the back surface 12 to the front surface 11 of the decorative laminate 10. The colored layer 45 covers the luminance adjustment layer 30. In the example shown in FIG. 14B, the colored layer 45 is observed through the functional layer 37, the shape-imparting layer 20, and the luminance adjustment layer 30. Therefore, the functional layer 37, the shape-imparting layer 20, and the luminance adjustment layer 30 are transparent. As shown in FIG. 2C, the colored layer 45 may be disposed closer to the front side surface 11 of the decorative laminate 10 than the shape-imparting layer 20 and the luminance adjustment layer 30. In this case, the shape-imparting layer 20 and / or the luminance adjustment layer 30 are observed through the colored layer 45. Therefore, the colored layer 45 is transparent.

[0186] The color layer 45 includes a pigment or a dye. The color layer 45 may be formed of the same material and by the same method as the color layer 30a described above. As shown in FIG. 14B, the color layer 45 may function as a planarizing layer that fills in the unevenness of the luminance adjustment layer 30.

[0187] In the decorative laminate 10 shown in FIG. 14B as well, the thickness of the decorative laminate 10 can be effectively made to appear thicker than its actual thickness.

[0188] <Decorative laminate shown in FIG. 14C> When the brightness adjustment layer 30 does not fill the unevenness of the shaping surface 20a, the decorative laminate 10 may have a filling layer 40 that fills the unevenness of the brightness adjustment layer 30. The filling layer 40 is a flattening layer that fills the unevenness of the brightness adjustment layer 30. In the example shown in FIG. 14C, the surface of the brightness adjustment layer 30 facing the filling layer 40 has unevenness corresponding to the unevenness of the shaping surface 20a. In the example shown in FIG. 14C, the bonding layer 38, the filling layer 40, the brightness adjustment layer 30, the shaping layer 20, and the functional layer 37 are laminated in this order in the direction from the back side 12 to the front side 11 of the decorative laminate 10. The filling layer 40 may be prepared by supplying an ionizing radiation curable resin composition onto the brightness adjustment layer 30 and curing it on the brightness adjustment layer 30.

[0189] The filling layer 40 may be a transparent or opaque resin layer. When the filling layer 40 is opaque, it can conceal at least a part of the article to which the decorative member 3 is applied. For example, in the example shown in FIG. 1B, the filling layer 40 is opaque, so that the decorative member 3 can conceal the sensor 5. That is, the filling layer 40 may also serve as a concealing layer 60 described later.

[0190] <Decorative laminate and decorative member shown in FIG. 2D> As shown in FIG. 2D and FIG. 14D, the decorative laminate 10 may have a backer layer 55. The backer layer 55 is a layer for reinforcing the decorative laminate 10 and maintaining the shape of the decorative laminate 10 as an integrated body. The decorative laminate 10 has the backer layer 55, which improves the strength of the decorative laminate 10. As a result, the decorative laminate 10 can be preformed before being bonded to the molding part 65, as described later. In the example shown in FIG. 2D and FIG. 14D, the backer layer 55, the bonding layer 56, the brightness adjustment layer 30, the shape-imparting layer 20, and the functional layer 37 are laminated in this order in the direction from the back side surface 12 to the front side surface 11 of the decorative laminate 10. As an example, the backer layer 55 forms the front side surface 11 or the back side surface 12 of the decorative laminate 10. In the example shown in FIG. 2D and FIG. 14D, the backer layer 55 forms the back side surface 12 of the decorative laminate 10.

[0191] Examples of materials for forming the backer layer include ABS resin, polyolefin resin, styrene resin, (meth)acrylic resin, vinyl chloride resin, and polycarbonate resin. As the polyolefin resin, polypropylene resin is preferable. Among these resins, ABS resin, polypropylene resin, and polycarbonate resin are particularly preferable. In addition, when the material for forming the molded portion 65 is ABS resin, the material for forming the backer layer is preferably ABS resin. When the material for forming the molded portion 65 is polypropylene resin, the material for forming the backer layer is preferably polypropylene resin. When the material for forming the molded portion 65 is polycarbonate resin, the material for forming the backer layer is preferably polycarbonate resin. The backer layer 55 may be a film-like member made of the above-mentioned material for forming the backer layer. The thickness of the backer layer 55 is, for example, 0.1 mm or more and 1.0 mm or less.

[0192] The backer layer 55 may be transparent or opaque. When the backer layer 55 is opaque, it can conceal at least a part of the article to which the decorative member 3 is applied. For example, in the example shown in FIG. 1B, the backer layer 55 is opaque, so that the decorative member 3 can conceal the sensor 5. That is, the backer layer 55 may also serve as a concealing layer 60 described later.

[0193] The bonding layer 56 bonds the backer layer 55 to the other layers of the decorative laminate 10. As a material for forming the bonding layer 56, the same material as that for the bonding layer 38 can be used.

[0194] <Method of manufacturing the decorative member shown in FIG. 2D> Next, a method for manufacturing the decorative member 3 shown in Fig. 2D will be described with reference to Fig. 10A to Fig. 10D, Fig. 14E and Fig. 14F. Fig. 14E and Fig. 14F are cross-sectional views showing a method for manufacturing the decorative laminate 10 shown in Fig. 2D and Fig. 14D.

[0195] First, a release layer 37a, a shape-imparting layer 20, and a brightness adjustment layer 30 are formed on a substrate 72 by the same method as that shown in Fig. 10A to Fig. 10D. Then, as shown in Fig. 14E, a bonding layer 56 is formed on the brightness adjustment layer 30. Next, as shown in Fig. 14F, a backer layer 55 is bonded to the bonding layer 56. Finally, the substrate 72 is peeled off from the decorative laminate 10. In this manner, the decorative laminate 10 shown in Fig. 14D is produced.

[0196] Next, the decorative laminate 10 is preformed using a preform mold corresponding to the shape of the front side surface 3a of the decorative member 3. The preformed decorative laminate 10 is then placed in a mold for forming the molded portion 65. Next, molten resin is introduced between the back side surface 12 (i.e., the backer layer 55) on the decorative laminate 10 and the inner surface of the mold, and the resin is solidified in the mold. As a result, the molded portion 65 joined to the decorative laminate 10 is molded in the mold, and the decorative member 3 shown in FIG. 14D is completed. Such a molding method for the decorative member 3 is known as insert molding.

[0197] <Decorative laminate and decorative member shown in FIG. 2E> In the above-mentioned example, the decorative laminate 10 has the functional layer 37 as the peeling layer 37a, but is not limited thereto. The functional layer 37 may be a support layer 37b that supports other layers of the decorative laminate 10. In the example shown in Fig. 2E and Fig. 14G, the backer layer 55, the bonding layer 56, the brightness adjustment layer 30, the shape-imparting layer 20, and the support layer 37b are laminated in this order in the direction from the back side surface 12 to the front side surface 11 of the decorative laminate 10.

[0198] The material constituting the support layer 37b may be any material having suitable support properties, such as acrylic ester, ABS, polyvinyl chloride, polymethyl methacrylate, polyethylene terephthalate, polyethylene naphthalate, polycarbonate, polystyrene, cyclic polyolefin, polypropylene, etc.

[0199] In the examples shown in Fig. 2E and Fig. 14G, the support layer 37b forms the front side surface 11 of the decorative laminate 10. Therefore, it is preferable that the support layer 37b has a scratch-resistant function. In this case, the support layer 37b also functions as a protective layer. By using such a support layer 37b to form the front side surface 11 of the decorative laminate 10, the risk of the uneven structure 25 being damaged by an external force applied to the front side surface 3a of the decorative member 3 is effectively reduced. The support layer 37b may have other functions such as an anti-reflection function, an anti-glare function, an anti-static function, and an anti-fouling function.

[0200] <Method of manufacturing the decorative member shown in FIG. 2E> Next, a method for manufacturing the decorative member 3 shown in Fig. 2E will be described with reference to Fig. 14H to Fig. 14J. Fig. 14H to Fig. 14J are cross-sectional views showing a method for manufacturing the decorative laminate 10 shown in Fig. 2E and Fig. 14G.

[0201] First, a flat substrate is prepared as the support layer 37b. Next, as shown in FIG. 14H, the mold layer 20 is formed on the support layer 37b. The mold layer 20 is formed by the same method as that shown in FIG. 10B and FIG. 10C. That is, first, a layer 29 of a precursor material of the mold layer 20 is formed on the support layer 37b. Next, the mold 100 is pressed against the layer 29, and then the layer 29 is hardened. This forms the mold layer 20.

[0202] Next, as shown in Fig. 14I, the brightness adjustment layer 30 is formed on the shaping surface 20a of the shaping layer 20. Next, as shown in Fig. 14J, the bonding layer 56 is formed on the brightness adjustment layer 30. Next, the backer layer 55 is bonded to the bonding layer 56. In this manner, the decorative laminate 10 shown in Fig. 14G is produced.

[0203] Next, the decorative laminate 10 is preformed using a preform mold corresponding to the shape of the front side surface 3a of the decorative member 3. The preformed decorative laminate 10 is then placed in a mold for forming the molded portion 65. Next, molten resin is introduced between the back side surface 12 (i.e., the backer layer 55) on the decorative laminate 10 and the inner surface of the mold, and the resin is solidified in the mold. As a result, the molded portion 65 bonded to the decorative laminate 10 is molded in the mold, and the decorative member 3 shown in FIG. 2E is completed.

[0204] When the functional layer 37 is the support layer 37b, the decorative laminate 10 does not need to include the bonding layer 56 or the backer layer 55. In the example shown in FIG. 2F , the luminance adjustment layer 30, the shape-imparting layer 20, and the support layer 37b are laminated in this order in a direction from the back side surface 12 toward the front side surface 11 of the decorative laminate 10. The support layer 37b forms the front side surface 11 of the decorative laminate 10, and the luminance adjustment layer 30 forms the back side surface 12 of the decorative laminate 10.

[0205] <Method of manufacturing the decorative member shown in FIG. 2F> Next, a method for producing the decorative member 3 shown in FIG. 2F will be described with reference to FIGS. 14H and 14I.

[0206] First, the shape-imparting layer 20 is formed on the support layer 37b by the same method as shown in Fig. 14H. Next, the brightness adjustment layer 30 is formed on the shape-imparting surface 20a of the shape-imparting layer 20 by the same method as shown in Fig. 14I. In this manner, the decorative laminate 10 shown in Fig. 2F is produced.

[0207] Next, the decorative laminate 10 is preformed using a preform mold corresponding to the shape of the front side surface 3a of the decorative member 3. The preformed decorative laminate 10 is then placed in a mold for forming the molded portion 65. Next, molten resin is introduced between the back side surface 12 (i.e., the brightness adjustment layer 30) on the decorative laminate 10 and the inner surface of the mold, and the resin is solidified in the mold. As a result, the molded portion 65 bonded to the decorative laminate 10 is molded in the mold, and the decorative member 3 shown in FIG. 2F is completed.

[0208] <Hidden Layer> The decorative laminate 10 may have an opaque concealing layer 60, as described below. The concealing layer 60 conceals at least a part of the article to which the decorative member 3 is applied or the molded portion 65. The concealing layer 60 may be composed of, for example, a pigment and / or a dye and a binder resin. The concealing layer 60 may be formed of the same material as the colored layer 45. As the pigment contained in the concealing layer 60, for example, a black pigment such as carbon black, a white pigment such as titanium oxide, or an aluminum-based pigment is preferable. By containing such a pigment in the concealing layer 60, the concealing property of the concealing layer 60 is improved. Alternatively, the concealing layer 60 may be formed by vapor-depositing a metal such as aluminum, indium, or tin on another layer of the decorative laminate 10.

[0209] <Other layers> The decorative laminate 10 may include layers other than the layers described above. For example, the decorative laminate 10 may include a pattern layer on which a pattern such as a figure, design, picture, photograph, character, mark, pictogram, letter, or number is formed. The pattern layer may also perform a design expression that displays a background on the decorative laminate 10. The pattern layer may be provided with, for example, a wood grain or marble pattern, a metallic texture, or a geometric pattern. The pattern layer may be a print layer formed by printing, or a transfer layer formed by transfer.

[0210] <Modifications of Decorative Members> In the example shown in Figures 2A to 2F, the decorative laminate 10 forms the front side 3a of the decorative member 3, but is not limited to this. As shown in Figures 2G to 2J, the decorative laminate 10 may form the back side 3b of the decorative member 3. In addition, in the example shown in Figures 2A to 2F, the shape-imparting layer 20 and the brightness adjustment layer 30 are laminated in this order in the direction from the front side 3a to the back side 3b of the decorative laminate 10, but is not limited to this. As shown in Figures 2G to 2I, the shape-imparting layer 20 and the brightness adjustment layer 30 may be laminated in this order in the direction from the back side 3b to the front side 3a of the decorative laminate 10.

[0211] <Decorative parts shown in Figure 2G> 2G, the decorative laminate 10 includes a functional layer 37, a molding layer 20, a brightness adjustment layer 30, and a bonding layer 38. The functional layer 37, the molding layer 20, the brightness adjustment layer 30, and the bonding layer 38 are laminated in this order in a direction from the back surface 3b to the front surface 3a of the decorative member 3. The bonding layer 38 forms the front surface 11 of the decorative laminate 10, and the functional layer 37 forms the back surface 12 of the decorative laminate 10. The bonding layer 38 bonds the back surface 67 of the molding portion 65 to other layers of the decorative laminate 10.

[0212] The decorative member 3 shown in Fig. 2G can be produced by the same method as the decorative member 3 shown in Fig. 2A. In the example shown in Fig. 2G, the brightness adjustment layer 30 and / or the shaping layer 20 are observed through the molding portion 65 and the bonding layer 38. Therefore, the molding portion 65 and the bonding layer 38 are transparent. The brightness adjustment layer 30 may also be transparent.

[0213] <Decorative parts shown in Fig. 2H> In the example shown in FIG. 2H, the decorative laminate 10 includes a functional layer 37, a molding layer 20, a brightness adjustment layer 30, a bonding layer 56, and a backer layer 55. The functional layer 37, the molding layer 20, the brightness adjustment layer 30, the bonding layer 56, and the backer layer 55 are laminated in this order in a direction from the back side surface 3b toward the front side surface 3a of the decorative member 3. The backer layer 55 forms the front side surface 11 of the decorative laminate 10, and the functional layer 37 forms the back side surface 12 of the decorative laminate 10. The backer layer 55 is bonded to the back side surface 67 of the molding portion 65.

[0214] The decorative member 3 shown in Fig. 2H can be produced by the same method as the decorative member 3 shown in Fig. 2D. In the example shown in Fig. 2H, the brightness adjustment layer 30 and / or the shaping layer 20 are observed through the molding portion 65, the backing layer 55, and the bonding layer 56. Therefore, the molding portion 65, the backing layer 55, and the bonding layer 56 are transparent. The brightness adjustment layer 30 may also be transparent.

[0215] <Decorative parts shown in Fig. 2I> In the example shown in FIG. 2I, the decorative laminate 10 includes a functional layer 37, a molding layer 20, a brightness adjustment layer 30, a bonding layer 56, and a backer layer 55. The functional layer 37, the molding layer 20, the brightness adjustment layer 30, the bonding layer 56, and the backer layer 55 are laminated in this order in a direction from the back side surface 3b toward the front side surface 3a of the decorative member 3. The backer layer 55 forms the front side surface 11 of the decorative laminate 10, and the functional layer 37 forms the back side surface 12 of the decorative laminate 10. The backer layer 55 is bonded to the back side surface 67 of the molding portion 65.

[0216] The decorative member 3 shown in Fig. 2I can be produced by the same method as the decorative member 3 shown in Fig. 2E. In the example shown in Fig. 2I, the brightness adjustment layer 30 and / or the shaping layer 20 are observed through the molding portion 65, the backing layer 55, and the bonding layer 56. Therefore, the molding portion 65, the backing layer 55, and the bonding layer 56 are transparent. The brightness adjustment layer 30 may also be transparent.

[0217] <Decorative parts shown in Fig. 2J> 2J, the decorative laminate 10 includes a concealing layer 60, a brightness adjustment layer 30, a molding layer 20, a functional layer 37, and an adhesive layer 38. The concealing layer 60, the brightness adjustment layer 30, the molding layer 20, the functional layer 37, and the adhesive layer 38 are laminated in this order in a direction from the back surface 3b to the front surface 3a of the decorative member 3. The adhesive layer 38 forms the front surface 11 of the decorative laminate 10, and the concealing layer 60 forms the back surface 12 of the decorative laminate 10. The adhesive layer 38 is bonded to the back surface 67 of the molding portion 65.

[0218] The decorative member 3 shown in FIG. 2J can be produced as follows. First, the shape-imparting layer 20 and the brightness adjustment layer 30 are laminated on one surface of the functional layer 37 by the same method as that shown in FIG. 14H and FIG. 14I. Next, as shown in FIG. 14K, a concealing layer 60 is formed on the brightness adjustment layer 30. Next, as shown in FIG. 14L, a bonding layer 38 is formed on the other surface of the functional layer 37. After the step shown in FIG. 14L, the bonding layer 38 is bonded to the back side surface 67 of the molding portion 65. This produces the decorative member 3 shown in FIG. 2J.

[0219] In the example shown in Fig. 2J, the brightness adjustment layer 30 and / or the shaping layer 20 are observed through the molding portion 65, the bonding layer 38, and the functional layer 37. Therefore, the molding portion 65, the bonding layer 56, and the functional layer 37 are transparent. The brightness adjustment layer 30 may also be transparent.

[0220] As shown in Figures 2G to 2J, when the decorative laminate 10 forms the front side surface 3a of the decorative member 3, and when the decorative laminate 10 is disposed between the rear side surface 3b of the decorative member 3 and the molded portion 65 (in other words, when the molded portion 65 is disposed between the front side surface 3a of the decorative member 3 and the decorative laminate 10), the molded portion 65 may be transparent and colored. In this case, too, the decorative laminate 10 may include a colored layer 45, as shown in Figures 2K and 2L. In the example shown in Figure 2L, the shape-imparting layer 20 and / or the brightness adjustment layer 30 are observed through the colored layer 45. For this reason, the colored layer 45 is transparent.

[0221] Alternatively, as shown in FIG. 2M and FIG. 2N, the decorative laminate 10 may include a colored layer 68. In the example shown in FIG. 2M, the colored layer 68 forms the front side surface 3a of the decorative laminate 10. In particular, in the example shown in FIG. 2M, the colored layer 68 covers the front side surface 66 of the molded portion 65. In the example shown in FIG. 2M, the molded portion 65 and the decorative laminate 10 are observed through the colored layer 68. Therefore, the colored layer 68 is transparent. In the example shown in FIG. 2N, the colored layer 68 covers the back side surface 67 of the molded portion 65. In the example shown in FIG. 2N, the decorative laminate 10 is observed through the colored layer 68. Therefore, the colored layer 68 is transparent. The colored layer 68 shown in FIG. 2M and FIG. 2N can be formed by applying a material similar to the colored layer 30a described above to the front side surface 66 or the back side surface 67 of the molded portion 65.

[0222] <Modification 2: Modification of Unit Optical Element> FIG. 4 shows an example in which a plurality of unit optical elements 13 have an outer contour 23a of a regular hexagonal shape in a plan view. However, the form of the unit optical elements 13 is not limited to this example. The outer contour 23a of the plurality of unit optical elements 13 may be a polygonal shape other than a hexagonal shape. For example, the outer contour 23a of each unit optical element 13 may be a polygonal shape such as a triangular shape, a rectangular shape, a pentagonal shape, a hexagonal shape, or an octagonal shape. FIG. 15 is a diagram showing a state in which a shape-imparting layer 20 having an example of the unit optical elements 13 in the second modification is viewed in a plan view. For example, as shown in FIG. 15, the unit optical elements 13 having an octagonal outer contour 23a may be arranged in a staggered manner. The outer contour 23a of the plurality of unit optical elements 13 may have a shape other than a polygonal shape. That is, the outer contour 23a of the unit optical elements 13 may include a curved portion or a portion extending in an arc shape. The outer contour 23a of the unit optical elements 13 is not particularly limited. The outer contour 23a of the unit optical element 13 may be, for example, a circle, a semicircle, an ellipse, a sector, a crescent, a heart, a letter shape, or the like. The unit optical elements 13 may have shapes different from each other. The unit optical elements 13 may be arranged in an irregular array. Furthermore, although not shown, the unit optical elements 13 may be arranged so as to overlap each other. The unit optical elements 13 may have outer contours 23a of shapes different from each other.

[0223] Another example of the shape of the plurality of unit optical elements 13 will be further described. In the above-mentioned embodiment, the example in which the concave-convex structure 25 is a linear Fresnel lens or has a structure in which linear Fresnel lenses are combined has been described. However, the shape of the concave-convex structure 25 is not limited to this. The concave-convex structure 25 may be a circular Fresnel lens. In this case, as shown in FIG. 16, the shape of each inclined surface 26A in plan view may be a perfect circle or an ellipse. The direction in which the major axis of the ellipse extends (hereinafter simply referred to as the major axis direction) may be different between the plurality of unit optical elements 13. For example, the major axis direction of one unit optical element 13 may be non-parallel to or perpendicular to the major axis direction of another unit optical element 13. As shown in FIG. 17, each inclined surface 26A may extend in an arc shape in plan view. In the example shown in FIG. 17, the inclined surface 26A of each unit optical element 13 extends along a circle centered on the optical axis Ax of the unit optical element 13. 18, the mold layer 20 may include a concave-convex structure 25 formed as a linear Fresnel lens and a concave-convex structure 25 formed as a circular Fresnel lens. The plurality of unit optical elements 13 may include unit optical elements 13 having different shapes of the outer contours 23a.

[0224] Further, another example of the unit optical element 13 in which the inclined surfaces 26A include a plurality of first inclined surfaces 26A1 and the connecting surfaces 26B include a plurality of first connecting surfaces 26B1 will be described. FIG. 19 is a diagram showing a plan view of a shape-imparting layer 20 having another example of the unit optical element 13 in the modified example 2. FIG. 20 is a diagram showing a cross section of the shape-imparting layer 20 along the line XX-XX in FIG. 19 together with a cross section of the brightness adjustment layer 30. In FIG. 20, the illustration of parts other than the shape-imparting layer 20 and the brightness adjustment layer 30 of the decorative laminate 10 is omitted. The first region 234 of the unit optical element 13 shown in FIG. 19 and FIG. 20 functions as a cone-shaped lens (axicon lens) shown in FIG. 21. In the example shown in FIG. 19 and FIG. 20, the plurality of first inclined surfaces 26A1 are formed by dividing the side surface of a cone. The first region 234 is a region extending from the inclined surface 26Ao located at the outermost position among the plurality of first inclined surfaces 26A1 to the inclined surface 26Ac located at the innermost position among the plurality of first inclined surfaces 26A1 when viewed in the normal direction (Z direction Dz) of the decorative laminate 10. The plurality of first inclined surfaces 26A1 are arranged in a direction toward a first reference line L1 extending along the normal direction of the decorative laminate 10. The plurality of first inclined surfaces 26A1 are inclined toward the first reference line L1. In the example shown in FIG. 19 and FIG. 20, the first reference line L1 coincides with the perpendicular line of the cone. The perpendicular line of the cone is a line perpendicularly drawn from the apex of the cone to the base surface.

[0225] In the example shown in FIG. 19 and FIG. 20, the unit optical element 13 in which the first region 234 functions as a lens having a right cone shape as shown in FIG. 21 has been described. However, the form of the unit optical element 13 is not limited to this. The first region 234 of the unit optical element 13 may function as a lens having a diagonal cone shape as shown in FIG. 22. FIG. 23 is a diagram showing a cross section of the shape-imparting layer 20 along the line XXIII-XXIII in FIG. 19 together with a cross section of the brightness adjustment layer 30. In FIG. 23, the illustration of parts of the decorative laminate 10 other than the shape-imparting layer 20 and the brightness adjustment layer 30 is omitted. The first region 234 may function as a lens having a cone shape with an elliptical bottom shape.

[0226] In the above example, the first region 234 has a shape that functions as a conical lens. However, the shape of the first region 234 is not limited to this. The first region 234 may function as a lens having a cone shape other than a cone. For example, the first region 234 may function as a lens having a cone shape with a polygonal bottom as shown in FIG. 24. FIG. 25 is a diagram showing a plan view of the shape-imparting layer 20 having another example of the unit optical element 13 in the second modification. The first inclined surface 26A1 may be formed as shown by the solid line in FIG. 25. In this specification, the term "cone" is a concept that includes not only a straight cone but also an oblique cone.

[0227] The first region 234 may function as a frustum-shaped lens. In this case, the first region 234 may function as a frustum-shaped lens obtained by removing the apex of a straight pyramid as shown in FIG. 26 and FIG. 27. The first region 234 may function as a frustum-shaped lens obtained by removing the apex of an oblique pyramid. FIG. 27 shows a cross section of the molding layer 20 and the brightness adjustment layer 30 when the concavo-convex structure 25 is configured so that the first region 234 functions as a frustum-shaped lens. In FIG. 27, the illustration of parts of the decorative laminate 10 other than the molding layer 20 and the brightness adjustment layer 30 is omitted.

[0228] As an example, the multiple first inclined surfaces 26A1 are shaped as side surfaces or parts of the side surfaces of a pyramid or a frustum at different height positions. In other words, the multiple first inclined surfaces 26A1 are configured to have a shape obtained by dividing the side surfaces of a pyramid or a frustum. A pyramid whose side surfaces or parts of the side surfaces are shaped by the multiple first inclined surfaces 26A1 is referred to as a first pyramid. A frustum whose side surfaces or parts of the side surfaces are shaped by the multiple first inclined surfaces 26A1 is referred to as a first frustum. The multiple first inclined surfaces 26A1 are shaped as side surfaces or parts of the side surfaces of the first pyramid or the first frustum at different height positions, so that the first region 234 can function as a lens in the shape of a first pyramid or a lens in the shape of a first frustum.

[0229] The first region 234 may function as a lens having an approximately pyramidal or approximately frustum shape. The first region 234 may function as a lens having a shape in which a part of a pyramid, a frustum, an approximately pyramidal or an approximately frustum is cut off at a virtual plane perpendicular to its bottom surface as shown in FIG. 28. The shape shown in FIG. 28 corresponds to a shape in which a part of a pyramid shown in FIG. 24 is cut off at a virtual plane perpendicular to its bottom surface. In this case, the first inclined surface 26A1 is formed as shown by a dashed line in FIG. 25. The unit optical element 13 with the reference numeral 13C in FIG. 25 formed to function as a lens having the shape shown in FIG. 28 is called an incomplete unit optical element 13C. The unit optical element 13 with the reference numeral 13D in FIG. 25 formed to function as a lens having the shape shown in FIG. 24 is called a complete unit optical element 13D. The incomplete unit optical element 13C has a shape in which a part of the complete unit optical element 13D is cut out at a virtual plane parallel to the normal direction (Z direction Dz) of the decorative laminate 10. In this case, the incomplete unit optical element 13C may be disposed such that the virtual plane cutting out the incomplete unit optical element 13C overlaps with a boundary 93 between a background region 92 and an object region 91 in a planar view.

[0230] Regardless of whether the first region 234 functions as a lens of any of the above shapes, the concave-convex structure 25 of the first region 234 is formed such that the multiple first inclined surfaces 26A1 are aligned in a direction toward a first reference line L1 extending along the normal direction (Z direction Dz) of the decorative laminate 10. The multiple first inclined surfaces 26A1 are inclined toward the first reference line L1. The multiple first inclined surfaces 26A1 form the shapes of side surfaces or parts of the side surfaces at different height positions of a pyramid, a frustum, an approximate pyramid, and an approximate frustum.

[0231] FIG. 27 corresponds to a cross section of the decorative laminate 10 when the shaping surface 20a functions as a lens having a frustum shape or a substantially frustum shape. As shown in FIG. 27, the unit optical element 13 includes a second region 235 adjacent to the first region 234 in the direction in which the first inclined surfaces 26A1 are arranged. As an example, in the second region 235, the shaping surface 20a is a flat surface or a curved surface. In the second region 235, the shaping surface 20a is a continuous flat surface or a curved surface. In the example shown in FIG. 27, in the second region 235, the shaping surface 20a is a flat surface. The second region 235 may be a spherical lens.

[0232] The second region 235 may include a plurality of second tilting surfaces 26A2 and a plurality of second connecting surfaces 26B2 connecting the adjacent second tilting surfaces 26A2. As shown in FIG. 29, a Fresnel lens structure may be formed in the second region 235. In this case, the second region 235 may include a plurality of second tilting surfaces 26A2 forming the Fresnel lens structure and a plurality of second connecting surfaces 26B2 connecting the adjacent second tilting surfaces 26A2. In the example shown in FIG. 29, the Fresnel lens structure includes the second tilting surface 26A2 and the second connecting surface 26B2 connecting the adjacent second tilting surfaces 26A2. The plurality of second tilting surfaces 26A2 correspond to a plurality of lens surfaces obtained by dividing a continuous lens surface of a spherical lens along a surface perpendicular to the thickness direction. In the example shown in FIG. 29, the Fresnel lens structure formed in the second region 235 functions as a convex lens, but the Fresnel lens structure is not limited to this. The Fresnel lens structure may function as a concave lens. By forming the Fresnel lens structure in the second region 235, it is possible to express a rich three-dimensional effect that is greater than the thickness of the mold-imparting layer 20, and to express a complex design.

[0233] The second region 235 may have a concave-convex structure 25 formed therein that functions as a lens having a cone shape, a cone shape, an approximately cone shape, or an approximately cone shape that is different from the cone shape or approximately cone shape corresponding to the first inclined surface 26A1 of the first region 234.

[0234] As an example, the second inclined surfaces 26A2 are shaped as side surfaces or parts of the side surfaces at different height positions of a pyramid or a frustum. In other words, the second inclined surfaces 26A2 are configured to have a shape obtained by dividing the side surface of a pyramid or a frustum. A pyramid having the side surfaces or parts of the side surfaces shaped by the second inclined surfaces 26A2 is referred to as a second pyramid. A frustum having the side surfaces or parts of the side surfaces shaped by the second inclined surfaces 26A2 is referred to as a second frustum. The second region 235 can function as a lens in the shape of a second pyramid or a lens in the shape of a second frustum by the second inclined surfaces 26A2 being shaped as side surfaces or parts of the side surfaces at different height positions of the second pyramid or the second frustum.

[0235] As an example, the first inclined surfaces 26A1 are shaped as side surfaces or parts of the side surfaces at different height positions of the first frustum. The second inclined surfaces 26A2 are shaped as side surfaces or parts of the side surfaces at different height positions of the second pyramid or the second frustum. In this case, the shape of the bottom surface of the first frustum and the shape of the bottom surface of the second pyramid or the second frustum may be different from each other. As an example, in the example shown by the two-dot chain line in FIG. 25, the first region 234 is formed to function as a lens in the shape of a frustum (first frustum) whose bottom surface is hexagonal. The second region 235 is formed to function as a lens in the shape of a cone whose bottom surface is circular, that is, a cone (second pyramid). In this case, the first inclined surfaces 26A1 may have the shape of side surfaces at different height positions of the first frustum, and the second inclined surfaces 26A2 may have the shape of side surfaces at different height positions of the second cone or frustum. In the unit optical element 13 shown by the two-dot chain line in FIG. 25, the first region 234 surrounds the second region 235 in a plan view.

[0236] FIG. 30 shows a cross section of the mold layer 20 along the line XXX-XXX in FIG. 25. In the example shown in FIG. 30, the second region 235 has a concave-convex structure 25 having a function different from that of the first inclined surface 26A1 of the first region 234. The second region 235 has a concave-convex structure 25 functioning as a lens having a cone shape, a frustum shape, a substantially cone shape, or a substantially frustum shape. In this case, the second inclined surface 26A2 may be aligned in a direction toward the second reference line L2 extending along the normal direction (Z direction Dz). The second inclined surface 26A2 may be inclined toward the second reference line L2. In the example shown in FIG. 25, the position of the second reference line L2 when the decorative laminate 10 is viewed in plan is fixed at one point. In the example shown, the second reference line L2 coincides with the perpendicular line of the cone, which is the second cone. The second reference line L2 may or may not coincide with the first reference line L1. In the example shown in FIG. 25, the second reference line L2 coincides with the first reference line L1.

[0237] Another example of the form of the plurality of unit optical elements 13 will be further described. For example, as shown in FIG. 31 and FIG. 32, the unit optical elements 13 having a rectangular outer contour 23a may be arranged in a square. The plurality of inclined surfaces 26A of the unit optical element 13 shown in FIG. 31 can be considered to be aligned in a direction toward the first reference line L1 shown in FIG. 31 and inclined toward the first reference line L1. The plurality of inclined surfaces 26A of the unit optical element 13 shown in FIG. 32 can be considered to be aligned in a direction toward the first reference line L1 shown in FIG. 32 and inclined toward the first reference line L1. In the example shown in FIG. 31, the uneven structure 25 of each unit optical element 13 is a linear Fresnel lens. FIG. 33 is a partial cross-sectional view showing a cross section of the shape-imparting layer 20 shown in FIG. 32 along the line XXXIII-XXXIII, together with a cross section of the brightness adjustment layer 30. In FIG. 33, the illustration of the parts other than the shape-imparting layer 20 and the brightness adjustment layer 30 of the decorative laminate 10 is omitted. As shown in FIG. 33, the inclined surface 26A and the connecting surface 26B adjacent to each other and included in the concave-convex structure 25 are connected at the boundary 26C. When the unit optical elements 13 having a rectangular outer contour 23a are arranged in a square array, the inclined surface 26A and the connecting surface 26B are arranged such that the boundary 26C included in one of the unit optical elements 13 extends in one direction in a plan view of one of the unit optical elements 13. In a plan view of one of the unit optical elements 13, the boundary 26C between the inclined surface 26A and the connecting surface 26B all extend in one direction. In this case, the direction in which the boundary 26C extends in one of the unit optical elements 13 in a plan view may be different from the direction in which the boundary 26C extends in another of the unit optical elements 13 in a plan view.

[0238] The case where the decorative laminate 10 has a plurality of unit optical elements 13 shown in Figs. 32 and 33 will be further described. In the example shown in Fig. 33, a plurality of inclined surfaces 26A included in one of the unit optical elements 13 are flat surfaces parallel to each other. A plurality of connecting surfaces 26B included in one of the unit optical elements 13 are flat surfaces parallel to each other. As shown in Fig. 32, the pitch P of the uneven structure 25 in one of the unit optical elements 13 may be different from the pitch P of the uneven structure 25 in another of the unit optical elements 13. The height H25 of the uneven structure 25 in one of the unit optical elements 13 may be different from the height H25 of the uneven structure 25 in the other of the unit optical elements 13.

[0239] The direction in which the boundary 26C extends in a plan view of one of the unit optical elements 13, the pitch P of the uneven structure 25, and the height H25 of the uneven structure 25 are adjusted for each unit optical element 13. As an example, it may be required to display a pseudo-three-dimensional shape in an area in which a plurality of unit optical elements 13 are provided by providing a plurality of unit optical elements 13. In this case, the direction in which the boundary 26C extends, the pitch P, and the height H25 of the uneven structure 25 may be adjusted for each unit optical element 13 according to the three-dimensional shape to be displayed. In this case, a desired three-dimensional shape can be displayed pseudo-wise by adjusting the direction in which the boundary 26C extends, the pitch P, and the height H25 of the uneven structure 25. As an example, it is assumed that when light is irradiated onto a three-dimensional shape to be displayed, a specific shadow is generated on the three-dimensional shape according to the direction of irradiating the light. In this case, the direction in which the boundary 26C extends, the pitch P, and the height H25 of the uneven structure 25 are adjusted so that the specific shadow is generated when light is irradiated onto the region in which the multiple unit optical elements 13 are provided. This allows the desired shadow of a three-dimensional shape to be displayed in a pseudo-three-dimensional manner. When multiple unit optical elements 13 are formed in the background region 92, the background region 92 can display a pseudo-three-dimensional shape.

[0240] <Modification 3: Modification of the molding layer> In the above-mentioned embodiment and each modified example, the shaping layer 20 in which the unit optical elements 13 are formed in one of the background region 92 and the object region 91 has been described. In the above-mentioned embodiment, the shaping surface 20a in the background region 92 and the object region 91 in which the unit optical elements 13 are not formed is flat. However, the shape of the shaping layer 20 is not limited to this. The shaping surface 20a in the background region 92 and the object region 91 in which the unit optical elements 13 are not formed may have unevenness 20f. The unevenness 20f can realize various design expressions. As an example, the shaping surface 20a has at least one of a plurality of linear convex portions 20g and a plurality of protrusions 20j in the object region 91, which will be described later.

[0241] FIG. 34 is a diagram showing an enlarged view of a part of the decorative laminate 10 of the modified example 3. FIG. 35A is a partial cross-sectional view of the decorative laminate 10 shown in FIG. 34, showing a cross-section along the line XXXV-XXXV. FIG. 35B is a diagram showing another example of the cross-section of the decorative laminate 10 of the modified example 3, different from the example shown in FIG. 35A. FIG. 35B shows an enlarged view of the vicinity of the interface between the shape-imparting layer 20 and the brightness adjustment layer 30 in a portion where the cross-sections of the multiple linear convex portions 20g appear in the cross-section of the decorative laminate 10. FIG. 36 is a diagram showing another example of the decorative laminate 10 of the modified example 3. FIG. 37 is a diagram showing another example of the decorative laminate 10 of the modified example 3. FIG. 38 is a partial cross-sectional view of the decorative laminate 10 shown in FIG. 37, showing a cross-section along the line XXXVIII-XXXVIII. The shape of the contour 94 of the object region 91 of the decorative laminate 10 of the modified example 3 is the same as the shape of the contour 94 of the object region 91 in the above-mentioned embodiment. Figures 34, 36, and 37 are enlarged views of an example of the mold layer 20 of the modified example 3, showing a portion corresponding to the region U of the mold layer 20 in the above-mentioned embodiment.

[0242] In the example shown in Figures 34 to 38, the shaping surface 20a in one of the background region 92 and the object region 91 where the unit optical elements 13 are not formed has unevenness 20f. In the example shown in Figures 34 to 38, the unit optical elements 13 are formed in the background region 92. The unit optical elements 13 are not formed in the object region 91. In the object region 91, the shaping surface 20a has unevenness 20f.

[0243] In the example shown in FIG. 34 to FIG. 36, the unevenness 20f has a plurality of linear convex portions 20g. That is, the shaping surface 20a has a plurality of linear convex portions 20g in the object region 91. Each of the plurality of linear convex portions 20g has a first surface 20h and a second surface 20i facing the first surface 20h. The first surface 20h and the second surface 20i of one linear convex portion 20g extend in the extending direction of the linear convex portion 20g. In the example shown in FIG. 35A, the inclination angle θ1 of the first surface 20h with respect to the normal direction (Z direction Dz) of the decorative laminate 10 is equal to the inclination angle θ2 of the second surface 20i with respect to the normal direction of the decorative laminate 10. In the example shown in FIG. 34 to FIG. 36, the first surface 20h and the second surface 20i of one linear convex portion 20g are directly connected to each other. Although not shown, the first surface 20h and the second surface 20i may be connected via a surface perpendicular to the normal direction of the decorative laminate 10.

[0244] As shown in Fig. 34, all of the linear protrusions 20g may be arranged parallel to one another. As shown in Fig. 36, the linear protrusions 20g may include a first linear protrusion 20g1 extending in a first extension direction and a second linear protrusion 20g2 extending in a second extension direction non-parallel to the first extension direction.

[0245] In the example shown in FIG. 35A, the cross section of the linear protrusions 20g cut along a plane perpendicular to the extension direction of the linear protrusions 20g is triangular. As shown in FIG. 35B, the cross section of the linear protrusions 20g cut along a plane perpendicular to the extension direction of the linear protrusions 20g may be rectangular. In the example shown in FIG. 35B, the cross section of the linear protrusions 20g cut along a plane perpendicular to the extension direction of the linear protrusions 20g is a quadrangle in which the tip of a triangle is cut off linearly. Although not shown, the cross section of the linear protrusions 20g cut along a plane perpendicular to the extension direction of the linear protrusions 20g may be a polygon other than a triangle or a quadrangle. In the example shown in FIG. 35A, the linear protrusions 20g protrude in the normal direction (Z direction Dz) of the decorative laminate 10. As shown in FIG. 35B, the multiple linear protrusions 20g may protrude in a direction forming an angle with the normal direction (Z direction Dz) of the decorative laminate 10.

[0246] The pitch P1 and height H1 of the linear protrusions 20g are adjusted according to the design to be expressed by providing the linear protrusions 20g. In this specification, the height H1 of the linear protrusions 20g means the height of the linear protrusion 20g having the maximum height.

[0247] For example, by adjusting the pitch P1 and height H1 of the multiple linear convex portions 20g, it is possible to suppress the occurrence of rainbow light in the area where the multiple linear convex portions 20g are provided, and to diffract white light in that area.

[0248] When white light is diffracted in the area where the linear protrusions 20g are provided, the height H1 of the linear protrusions 20g is preferably 0.5 μm or more and 50 μm or less. The height H1 is more preferably 1 μm or more and 10 μm or less, and even more preferably 1.5 μm or more and 5 μm or less. When the height H1 is 1 μm or more, it is possible to suppress the occurrence of rainbow light on the front side surface 11 of the decorative laminate 10 due to the linear protrusions 20g. When the height H1 is 2 μm or more, it is possible to make the design displayed by optical action even easier to see. When the height H1 is 10 μm or less, it is possible to form the linear protrusions 20g into a shape that is easy to shape.

[0249] When white light is diffracted in the region where the linear protrusions 20g are provided, the pitch P1 of the linear protrusions 20g is preferably 5 μm or more and 100 μm or less. The pitch P1 is more preferably 10 μm or more and 50 μm or less, and even more preferably 15 μm or more and 30 μm or less. When the pitch P1 is 10 μm or more, it is possible to suppress the occurrence of rainbow light on the front side surface 11 of the decorative laminate 10 due to the linear protrusions 20g. When the pitch P1 is 10 μm or more, it is possible to more effectively suppress the display of a rainbow-like design in the region where the linear protrusions 20g are provided. When the pitch P1 is 100 μm or less, it is possible to realize a small size of the linear protrusions 20g.

[0250] By adjusting the pitch P1 and height H1 of the plurality of linear protrusions 20g, it is also possible to generate rainbow light in the region where the plurality of linear protrusions 20g are provided.

[0251] When rainbow light is generated in the region where the linear protrusions 20g are provided, the height H1 of the linear protrusions 20g is preferably 0.1 μm or more and 10.0 μm or less. The height H1 is more preferably 0.2 μm or more and 6.0 μm or less, and even more preferably 0.2 μm or more and 3.0 μm or less. When the height H1 is 3 μm or less, the linear protrusions 20g can be easily shaped. When the height H1 is 0.2 μm or more, rainbow light can be effectively generated on the front side surface 11 of the decorative laminate 10 by the linear protrusions 20g.

[0252] When it is desired to generate rainbow light in the region where the linear protrusions 20g are provided, the pitch P1 of the linear protrusions 20g is preferably 0.5 μm or more and less than 10.0 μm. The pitch P1 is more preferably 1.0 μm or more and 6.0 μm or less, and even more preferably 1.0 μm or more and 4.0 μm or less. When the pitch P1 is 0.5 mm or more, the linear protrusions 20g can be easily shaped. When the pitch P1 is 4.0 μm or less, the linear protrusions 20g can effectively generate rainbow light on the front side surface 11 of the decorative laminate 10.

[0253] In the example shown in Fig. 37 and Fig. 38, the unevenness 20f has a plurality of protrusions 20j. That is, the shaping surface 20a has a plurality of protrusions 20j in the object region 91. The plurality of protrusions 20j protrude in the normal direction (Z direction Dz) of the decorative laminate 10. The plurality of protrusions 20j have an inclined surface 20k inclined with respect to the normal direction of the decorative laminate 10. In the example shown in Fig. 37 and Fig. 38, the plurality of protrusions 20j have a cone shape. Although not shown, the plurality of protrusions 20j may have a truncated cone shape, a pyramid shape, or a truncated pyramid shape.

[0254] According to the plurality of protrusions 20j, the light incident on the region of the shaping surface 20a where the plurality of protrusions 20j are provided can be reflected along the path L3 shown in FIG. 38. This allows the region where the plurality of protrusions 20j are provided to have a glossy appearance. This allows the region where the plurality of protrusions 20j are provided to have a glossy appearance like that of a metal surface without providing a film of a metal material or the like.

[0255] <Modification 4: Modification of the molding layer> In the above-described embodiment and each modified example, the shape-imparting layer 20 in which the unit optical elements 13 are formed in the background region 92 has been described. In the above-described embodiment and each modified example, the unit optical elements 13 are not formed in the object region 91. However, the form of the shape-imparting layer 20 is not limited to this.

[0256] Fig. 39 is a diagram showing an example of the decorative laminate 10 of Modification 4. Fig. 40 is a partial cross-sectional view of the decorative laminate 10, showing a cross-section along the line XL-XL of the decorative laminate 10 shown in Fig. 39. The shape of the contour 94 of the object region 91 of the decorative laminate 10 of Modification 4 is the same as the shape of the contour 94 of the object region 91 in the above-mentioned embodiment. Fig. 39 is an enlarged view showing a portion of the example of the decorative laminate 10 of Modification 4, which corresponds to the region U of the mold layer 20 in the above-mentioned embodiment.

[0257] In the example shown in Fig. 39 and Fig. 40, the unit optical elements 13 are formed in the object region 91. The unit optical elements 13 formed in the object region 91 are also referred to as second unit optical elements. In the example shown in Fig. 39, a plurality of unit optical elements 13 are formed in the object region 91. In other words, the decorative laminate 10 has a plurality of second unit optical elements as a plurality of unit optical elements 13. In the example shown in Fig. 39, a plurality of unit optical elements 13 are formed in the object region 91. In the example shown in Fig. 39 and Fig. 40, a portion of the shaping surface 20a located in the background region 92 is a flat surface perpendicular to the normal direction (Z direction Dz) of the decorative laminate 10.

[0258] According to the shaping layer 20 shown in FIG. 39 and FIG. 40, the action of the unit optical elements 13 can give the observer an impression that the shaping surface 20a in the object region 91 is deeper than the shaping surface 20a in the background region 92. By changing the form of the plurality of unit optical elements 13 provided in the object region 91, it is also possible to give the impression that the shaping surface 20a in the object region 91 protrudes from the shaping surface 20a in the background region 92. As an example, a plurality of unit optical elements 13 having a rectangular outer contour 23a and arranged in a square, which are provided in the background region 92 in the example shown in FIG. 32 and FIG. 33, may be provided in the object region 91. In this case, the direction in which the boundary 26C extends in a plan view of one of the unit optical elements 13, the pitch P of the concave-convex structure 25, and the height H25 of the concave-convex structure 25 may be adjusted for each unit optical element 13. By adjusting the extending direction of the boundary 26C, the pitch P, and the height H25 of the uneven structure 25, a desired three-dimensional shape can be displayed in the object area 91 in a pseudo manner.

[0259] The background region 92 will be described when no unit optical elements 13 are formed in the background region 92. In this case, in the background region 92, the shaping surface 20a may be a flat surface perpendicular to the normal direction (Z direction Dz) of the decorative laminate 10. In the background region 92, the shaping surface 20a may have the irregularities 20f described above in Modification 3.

[0260] <Modification 5: Modification of the molding layer> When the unit optical elements 13 are formed in the object region 91, the shape of the unit optical elements 13 is not limited to the shape described above in Modification 4. In other words, when the decorative laminate 10 has second unit optical elements as the unit optical elements 13, the shape of the second unit optical elements is not limited to the shape described above in Modification 4.

[0261] FIG. 41 is a plan view showing an example of the shape-imparting layer 20 of the fifth modified example. FIG. 42 is a view showing a cross section of the shape-imparting layer 20 along the line XLII-XLII shown in FIG. 41 together with a cross section of the brightness adjustment layer 30. FIG. 43 is a plan view showing an example of the shape-imparting layer 20 of the fifth modified example. FIG. 44 is a view showing a cross section of the shape-imparting layer 20 along the line XLIV-XLIV shown in FIG. 43 together with a cross section of the brightness adjustment layer 30. FIG. 45 is a plan view showing an example of the shape-imparting layer 20 of the fifth modified example. FIG. 46 is a view showing a cross section of the shape-imparting layer 20 along the line XLVI-XLVI shown in FIG. 45 together with a cross section of the brightness adjustment layer 30. The shape of the contour 94 of the object region 91 of the decorative laminate 10 of the fifth modified example is the same as the shape of the contour 94 of the object region 91 in the above-mentioned embodiment. In FIG. 42, FIG. 44, and FIG. 46, the illustration of the parts other than the shape-imparting layer 20 of the decorative laminate 10 is omitted.

[0262] In the examples shown in Figs. 42, 44, and 46, the concave-convex structure 25 is formed on the shaping surface 20a in the object region 91. The adjacent inclined surfaces 26A and the connecting surfaces 26B of the concave-convex structure 25 are connected at the boundary 26C. The inclined surfaces 26A and the connecting surfaces 26B are arranged so that the boundary 26C between the adjacent inclined surfaces 26A and the connecting surfaces 26B extends along the contour 94 of the object region 91 in a plan view. In the examples shown in Figs. 42, 44, and 46, the decorative laminate 10 has a second unit optical element as the unit optical element 13. The inclined surfaces 26A and the connecting surfaces 26B of the second unit optical element are arranged so that the boundary 26C between the adjacent inclined surfaces 26A and the connecting surfaces 26B extends along the contour 94 of the object region 91 in a plan view. When such a concave-convex structure 25 is formed in the object region 91, it is considered that one unit optical element 13 having the concave-convex structure 25 is formed in the object region 91. In other words, it can be considered that the decorative laminate 10 has one second unit optical element as the unit optical element 13. By arranging the multiple inclined surfaces 26A and the multiple connecting surfaces 26B as described above, the shape of the contour 94 of the object region 91 can be accentuated. This makes it possible to leave a strong impression of the object 90 on the observer. Furthermore, a three-dimensional effect can be imparted to the displayed object 90. As an example, the object 90 may give the impression of protruding from the background region 92.

[0263] 41 and 42, the unit optical elements 13 (second unit optical elements) are formed over the entire object region 91. In the example shown in Fig. 42, the inclined surface 26A is a flat surface inclined with respect to the normal direction of the decorative laminate 10. In the example shown in Fig. 42, the inclination angles of the multiple inclined surfaces 26A with respect to the normal direction of the decorative laminate 10 are all equal.

[0264] In the examples shown in Figs. 43 and 44, the unit optical element 13 (second unit optical element) is formed in a part of an area 91A adjacent to a contour 94 in the object area 91. In an area 91B of the object area 91 surrounded by the area 91A, the shaping surface 20a is a flat surface perpendicular to the normal direction (Z direction Dz) of the decorative laminate 10. A boundary 91C between the area 91A and the area 91B extends along the contour 94 of the object area 91. In the example shown in Fig. 44, the inclined surface 26A is a flat surface inclined with respect to the normal direction of the decorative laminate 10. In the example shown in Fig. 44, the inclined surfaces 26A have the same inclination angle with respect to the normal direction of the decorative laminate 10.

[0265] In both Figures 42 and 44, each of the multiple inclined surfaces 26A is inclined so that the shaping surface 20a of the shaping layer 20 approaches the front side surface 11 as it moves away from the contour 94 in a direction perpendicular to the normal direction of the decorative laminate 10.

[0266] 41 and 42 and the shape-imparting layer 20 shown in Fig. 43 and 44 can accentuate the shape of the contour 94 of the object region 91. Furthermore, a three-dimensional effect can be imparted to the displayed object 90.

[0267] 45 and 46, object region 91 has a first object region 91D adjacent to contour 94 of object region 91, and a second object region 91E surrounded by first object region 91D. In the example shown in Fig. 45, first object region 91D surrounds second object region 91E in plan view. Unit optical element 13 (second unit optical element) has a first concave-convex structure 251 formed in first object region 91D, and a second concave-convex structure 252 formed in second object region 91E.

[0268] As shown in FIG. 46, the angles of the inclined surfaces 26A included in the first concave-convex structure 251 with respect to the normal direction of the decorative laminate 10 are constant. The angles of the inclined surfaces 26A included in the second concave-convex structure 252 with respect to the normal direction of the decorative laminate 10 are different from each other. The inclined surfaces 26A included in the first concave-convex structure 251 are referred to as first object inclined surfaces 26A3. The inclined surfaces 26A included in the second concave-convex structure 252 are referred to as second object inclined surfaces 26A4. In the example shown in FIG. 46, the inclination angles of the first object inclined surfaces 26A3 with respect to the normal direction of the decorative laminate 10 are all equal. In the example shown in FIG. 46, the second object inclined surfaces 26A4 have shapes corresponding to a plurality of lens surfaces obtained by dividing a continuous curved surface. In a cross section of the mold layer 20 cut along a plane parallel to the normal direction of the decorative laminate 10, the multiple second object tilting surfaces 26A4 may have a shape corresponding to multiple lens surfaces obtained by dividing a continuous convex lens surface. The second object tilting surface 26A4 may form a Fresnel lens structure. Each of the multiple first object tilting surfaces 26A3 and each of the multiple second object tilting surfaces 26A4 are inclined so that the mold surface 20a of the mold layer 20 approaches the front side surface 11 as it moves away from the contour 94 in a direction perpendicular to the normal direction of the decorative laminate 10. As an example, the inclination angle θ4 of the first object tilting surface 26A3 with respect to the normal direction of the decorative laminate 10 is equal to or greater than the inclination angle of an arbitrary tangent plane tangent to the second object tilting surface 26A4 with respect to the normal direction of the decorative laminate 10.

[0269] 45, boundary 26C1, which is one of boundaries 26C between adjacent inclined surfaces 26A and connecting surfaces 26B, forms the boundary between first object region 91D and second object region 91E. The boundary between first object region 91D and second object region 91E extends along contour 94 of object region 91.

[0270] The shape of the contour 94 of the object region 91 can also be accentuated by the shape-imparting layer 20 shown in FIG. 45 and FIG. 46. Furthermore, a three-dimensional effect can be imparted to the displayed object 90. According to the shape-imparting layer 20 shown in FIG. 45 and FIG. 46, the first object region 91D and the second object region 91E can be given different impressions to the observer who observes the object region 91. In the shape-imparting layer 20 shown in FIG. 45 and FIG. 46, a first uneven structure 251 including a plurality of first object tilting surfaces 26A3 having the above-mentioned characteristics is formed in the first object region 91D. This first object region 91D can give the impression that the second object region 91E is greatly protruding from the background region 92. In the shape-imparting layer 20 shown in FIG. 45 and FIG. 46, a second uneven structure 252 including a plurality of second object tilting surfaces 26A4 having the above-mentioned characteristics is formed in the second object region 91E. This second object region 91E can give the impression that the object 90 has a rounded shape in the second object region 91E.

[0271] <Modification 6: Modification of Decorative Laminate> In the above-mentioned embodiment and each modified example, an example in which the unit optical element 13 is formed in either the background region 92 or the object region 91 has been described. However, the form of the shape-imparting layer 20 is not limited to this. The unit optical element 13 may be formed in both the background region 92 and the object region 91. That is, the decorative laminate 10 may have a plurality of unit optical elements 13 including a first unit optical element formed in the background region 92 and a second unit optical element formed in the object region 91. In this case, the form of the unit optical element 13 (first unit optical element) formed in the background region 92 may be different from the form of the unit optical element 13 (second unit optical element) formed in the object region 91. The arrangement pattern of the unit optical element 13 (first unit optical element) formed in the background region 92 may be different from the arrangement pattern of the unit optical element 13 (second unit optical element) formed in the object region 91. A plurality of unit optical elements 13 may be formed in one of the object region 91 and the background region 92, and one unit optical element 13 may be formed in the other.

[0272] As an example, the decorative laminate 10 may have a plurality of unit optical elements including a plurality of first unit optical elements formed in the background region 92 and a second unit optical element formed in the object region 91. In this case, the decorative laminate 10 may have one second unit optical element. That is, a plurality of unit optical elements 13 (first unit optical elements) may be formed in the background region 92, and one unit optical element 13 (second unit optical element) may be formed in the object region 91. In this case, the plurality of unit optical elements 13 (first unit optical elements) formed in the background region 92 may be regularly arranged in the background region 92. At least a portion of the plurality of unit optical elements 13 (first unit optical elements) formed in the background region 92 may have the same shape. In the object region 91, a plurality of inclined surfaces 26A and a plurality of connecting surfaces 26B may be arranged so that the boundary 26C extends along the contour 94 in a plan view. In this case, the effect of the background region 92 giving the impression that the object 90 stands out from the background region 92 and the effect of the object region 91 giving the impression that the object 90 protrudes from the background region 92 can be simultaneously achieved.

[0273] An example of a decorative laminate 10 having a plurality of unit optical elements including a plurality of first unit optical elements formed in a background region 92 and a second unit optical element formed in an object region 91 will be described. In the decorative laminate 10, a plurality of inclined surfaces 26A and a plurality of connecting surfaces 26B in the second unit optical element may be arranged such that a boundary 26C between adjacent inclined surfaces 26A and connecting surfaces 26B extends along a contour 94 of the object region 91 in a plan view. In this case, the form of the second unit optical element may be the same as any one of the unit optical elements 13 (second unit optical element) shown in Figs. 41 and 42, the unit optical elements 13 (second unit optical element) shown in Figs. 43 and 44, and the unit optical elements 13 (second unit optical element) shown in Figs. 45 and 46. In the decorative laminate 10, the second unit optical element may be formed in a part of a region 91A adjacent to the contour 94 in the object region 91. In this case, the shape of the second unit optical element may be the same as the shape of the unit optical element 13 (second unit optical element) shown in FIG. 43 and FIG. 44. In the decorative laminate 10, the object region 91 may have a first object region 91D adjacent to the contour 94 of the object region 91 and a second object region 91E surrounded by the first object region 91D. In this case, the second unit optical element may have a first concave-convex structure 251 formed in the first object region 91D and a second concave-convex structure 252 formed in the second object region 91E. In this case, the angle of the multiple inclined surfaces 26A included in the first concave-convex structure 251 with respect to the normal direction of the decorative laminate 10 may be constant. In this case, the angle of the multiple inclined surfaces 26A included in the second concave-convex structure 252 with respect to the normal direction of the decorative laminate 10 may be different from each other. In this case, the shape of the second unit optical element may be the same as the shape of the unit optical element 13 (second unit optical element) shown in Figures 45 and 46. In the decorative laminate 10, the shape of the multiple first unit optical elements may be the same as the shape of the unit optical element 13 (first unit optical element) shown in Figure 4.

[0274] <Modification 7: Modification of the decorative laminate and the manufacturing method of the decorative laminate> The brightness adjustment layer 30 may be formed on the shaping surface 20a in either the object region 91 or the background region 92. For example, when manufacturing a decorative laminate 10 in which unit optical elements 13 are formed in the background region 92, the brightness adjustment layer 30 may be formed on the shaping surface 20a in the object region 91.

[0275] FIG. 47 is an example of a cross-sectional view of the decorative laminate 10 of the seventh modified example. The decorative laminate 10 shown in FIG. 47 is manufactured by a manufacturing method of the decorative laminate 10 of the seventh modified example, which will be described later. In the example shown in FIG. 47, the unit optical elements 13 are formed in the background region 92. The unit optical elements 13 are not formed in the object region 91. The decorative laminate 10 shown in FIG. 47 includes a luminance adjustment layer 30 covering the shaping surface 20a. The luminance adjustment layer 30 is formed in the object region 91. The luminance adjustment layer 30 is formed on the shaping surface 20a in the object region 91. The luminance adjustment layer 30 is not formed in the background region 92.

[0276] The brightness adjustment layer 30 of the decorative laminate 10 of the seventh modification may be any one of the above-mentioned colored layer 30a, reflective layer 30b, or refractive index modulation layer 30c. As an example, the brightness adjustment layer 30 of the decorative laminate 10 of the seventh modification is a deposition film of a metal material or a printed layer containing a metal-based pigment. The deposition film of a metal material and the printed layer containing a metal-based pigment both correspond to the above-mentioned reflective layer 30b. In the example shown in FIG. 47, a reflective layer 30b is formed as the brightness adjustment layer 30.

[0277] The decorative laminate 10 of the seventh modification further includes an additional luminance adjustment layer 36 formed in one of the object region 91 and the background region 92 where the luminance adjustment layer 30 is not formed, and covering the shaping surface 20a. As an example, the additional luminance adjustment layer 36 directly contacts the shaping surface 20a in the one of the object region 91 and the background region 92 where the luminance adjustment layer 30 is not formed. In the example shown in FIG. 47, the luminance adjustment layer 30 is not formed in the background region 92. The additional luminance adjustment layer 36 is formed in the background region 92 and covers the shaping surface 20a.

[0278] As an example, the additional luminance adjustment layer 36 is a colored layer, a reflective layer, or a refractive index modulation layer. As a description of the additional luminance adjustment layer 36 that is a colored layer, the description of the luminance adjustment layer 30 that is a colored layer 30a can be applied, unless there is a contradiction. As a description of the additional luminance adjustment layer 36 that is a reflective layer, the description of the luminance adjustment layer 30 that is a reflective layer 30b can be applied, unless there is a contradiction. As a description of the additional luminance adjustment layer 36 that is a refractive index modulation layer, the description of the luminance adjustment layer 30 that is a refractive index modulation layer 30c can be applied, unless there is a contradiction. In the example shown in FIG. 47, the additional luminance adjustment layer 36 is a colored layer 36a.

[0279] The manufacturing method of the decorative laminate 10 shown in FIG. 47 includes a step of applying a coating material 39 so as to cover the background region 92, a step of forming a brightness adjustment layer 30, and a step of removing the brightness adjustment layer 30 from the shaping surface 20a in the background region 92. These steps can be performed after the step of preparing the shaping layer 20 and before the step of preparing a layer that covers the brightness adjustment layer 30. The manufacturing method of the decorative laminate 10 shown in FIG. 47 includes a step of forming an additional brightness adjustment layer 36 on the shaping surface 20a so as to cover at least the region on the shaping surface 20a from which the brightness adjustment layer 30 has been removed. The step of forming the additional brightness adjustment layer 36 can be performed after the step of removing the brightness adjustment layer 30.

[0280] In the step of applying the coating material 39, the coating material 39 is applied to the shaping surface 20a so as to cover the background region 92. An example of the step of applying the coating material 39 is shown in FIG. 48A. In the example shown in FIG. 48A, a laminate in which a peeling layer 37a is formed on a substrate 72 and a shape-imparting layer 20 is formed on the peeling layer 37a as shown in FIG. 10C is prepared, and the coating material 39 is applied to the shaping surface 20a of the shape-imparting layer 20 of the laminate. The laminate in which a peeling layer 37a is formed on a substrate 72 and a shape-imparting layer 20 is formed on the peeling layer 37a can be prepared by a method similar to the method shown in FIG. 10A to FIG. 10C. The coating material 39 is applied to the shaping surface 20a so as not to cover the object region 91. The material of the coating material 39 is not particularly limited as long as the luminance adjustment layer 30 can be removed by removing the coating material 39 from the shaping surface 20a in the step of removing the luminance adjustment layer 30 described later. As an example, polyvinyl alcohol (PVA) is printed in a predetermined pattern on the shape-imparting surface 20a as the coating material 39. The polyvinyl alcohol pattern printed on the shape-imparting surface 20a as the coating material 39 is also referred to as a PVA pattern.

[0281] In the step of forming the luminance adjustment layer 30, as shown in FIG. 48B, the luminance adjustment layer 30 is formed on the shaping surface 20a and the application matter 39. In the example shown in FIG. 48B, the luminance adjustment layer 30 is a reflective layer 30b. As described above in the first modification, the reflective layer 30b can be formed by deposition of a metal material or an inorganic material, or coating of a metal material or an inorganic material. As an example, the luminance adjustment layer 30 is formed on the shaping surface 20a in the object region 91 so as to be in direct contact with the shaping surface 20a of the shaping layer 20. In the background region 92, the luminance adjustment layer 30 is formed on the application matter 39.

[0282] In the step of removing the brightness adjustment layer 30, the application material 39 is removed from the shaping surface 20a, thereby removing the brightness adjustment layer 30 from the shaping surface 20a in the background region 92. An example of the step of removing the brightness adjustment layer 30 is shown in FIG. 48C. When the application material 39 is a PVA pattern, in the step of removing the brightness adjustment layer 30, the application material 39 and the shaping surface 20a on which the brightness adjustment layer 30 is provided are washed with water, thereby removing the PVA pattern, which is the application material 39. As an example, in the background region 92, the brightness adjustment layer 30 is formed on the application material 39. Therefore, in the background region 92, the brightness adjustment layer 30 on the application material 39 can also be removed by removing the application material 39. In the object region 91, the application material 39 does not exist between the brightness adjustment layer 30 and the shaping layer 20. Therefore, the brightness adjustment layer 30 formed on the shaping surface 20a in the object region 91 is not removed by removing the application material 39, but remains on the shaping surface 20a. In this manner, the luminance adjustment layer 30 can be removed from the background region 92 while leaving the luminance adjustment layer 30 in the object region 91.

[0283] After the step of removing the brightness adjustment layer 30, a step of forming the additional brightness adjustment layer 36 is performed. In this step, the additional brightness adjustment layer 36 is formed on the imprinting surface 20a so as to cover at least the area on the imprinting surface 20a from which the brightness adjustment layer 30 has been removed. As described above, when the brightness adjustment layer 30 formed on the imprinting surface 20a is removed in the background region 92, the additional brightness adjustment layer 36 is formed on the imprinting surface 20a so as to cover at least the background region 92 on the imprinting surface 20a. As an example, the additional brightness adjustment layer 36 is formed on the brightness adjustment layer 30 in the object region 91 and on the imprinting surface 20a in the background region 92. When manufacturing the decorative laminate 10 shown in FIG. 47, a colored layer 36a is formed as the additional brightness adjustment layer 36. Thereby, the decorative laminate 10 shown in FIG. 47 can be manufactured on the peeling layer 37a formed on the base material 72. In the example shown in FIG. 47, in the background region 92, a colored layer 36a is formed on the shape-imparting surface 20a of the shape-imparting layer 20 so as to be in direct contact with the shape-imparting surface 20a.

[0284] By the process of forming the additional luminance adjustment layer 36, the additional luminance adjustment layer 36 can be formed on the shaping surface 20a of the shaping layer 20 in the background region 92 so as to be in direct contact with the shaping surface 20a of the shaping layer 20. In the example shown in Fig. 47, the additional luminance adjustment layer 36 is formed on the luminance adjustment layer 30 in the object region 91. By the process of forming the additional luminance adjustment layer 36, the additional luminance adjustment layer 36 can be formed on the shaping surface 20a in the background region 92 while forming the luminance adjustment layer 30 on the shaping surface 20a in the object region 91.

[0285] When the manufacturing method of the decorative laminate 10 of the modified example 7 further includes a step of forming the additional brightness adjustment layer 36 on the shaping surface 20a, the additional brightness adjustment layer 36 may include a reflective layer 36b. FIG. 48D is an example of a cross-sectional view of the decorative laminate 10 in the modified example 7 in which the additional brightness adjustment layer 36 includes a reflective layer 36b. In an example of the manufacturing method of the decorative laminate 10 of the modified example 7, the brightness adjustment layer 30 is removed from the shaping surface 20a in the background region 92. In this case, in the step of forming the reflective layer 36b as the additional brightness adjustment layer 36, the reflective layer 36b is formed as the additional brightness adjustment layer 36 on the shaping surface 20a so as to cover at least the background region 92 on the shaping surface 20a. In the example shown in FIG. 48D, the additional brightness adjustment layer 36 includes a reflective layer 36b and a colored layer 36a. Such an additional brightness adjustment layer 36 can be formed by the following method. In the step of forming the additional brightness adjusting layer 36, the reflective layer 36b is formed on the shaping surface 20a so as to cover at least the background region 92 on the shaping surface 20a. Next, the colored layer 36a is formed on the reflective layer 36b.

[0286] Another example of the decorative laminate 10 of the seventh modification and the manufacturing method of the decorative laminate 10 will be described. The reflective layer 30b may be formed on the shaping surface 20a in the background region 92, and the reflective layer 30b may not be formed on the shaping surface 20a in the object region 91. More specifically, when manufacturing the decorative laminate 10 in which the unit optical elements 13 are formed in the object region 91, the reflective layer 30b may be formed on the shaping surface 20a in the background region 92. FIG. 49 is another example of a cross-sectional view of the decorative laminate 10 manufactured by the manufacturing method of the decorative laminate 10 of the seventh modification, different from FIG. 47 and FIG. 48D.

[0287] In the example shown in FIG. 49, the unit optical elements 13 are formed in the object region 91. The unit optical elements 13 are not formed in the background region 92. In the example shown in FIG. 49, the luminance adjustment layer 30 is formed in the background region 92. The luminance adjustment layer 30 is not formed in the object region 91. The decorative laminate 10 shown in FIG. 49 further includes an additional luminance adjustment layer 36 formed in one of the object region 91 and the background region 92 where the luminance adjustment layer 30 is not formed and covering the shaping surface 20a. In the example shown in FIG. 49, the luminance adjustment layer 30 is not formed in the object region 91. The additional luminance adjustment layer 36 is formed in the object region 91 and covers the shaping surface 20a.

[0288] The manufacturing method of the decorative laminate 10 shown in FIG. 49 includes a step of applying a coating material 39 so as to cover the object region 91, a step of forming a brightness adjustment layer 30, and a step of removing the brightness adjustment layer 30 from the shaping surface 20a in the object region 91. These steps can be performed after the step of producing the shaping layer 20 and before the step of producing a layer that covers the brightness adjustment layer 30. The manufacturing method of the decorative laminate 10 shown in FIG. 49 includes a step of forming an additional brightness adjustment layer 36 on the shaping surface 20a so as to cover at least the region on the shaping surface 20a from which the brightness adjustment layer 30 has been removed. The step of forming the additional brightness adjustment layer 36 can be performed after the step of removing the brightness adjustment layer 30.

[0289] In the step of applying the coating material 39, the coating material 39 is applied onto the shaping surface 20a so as to cover the object region 91. An example of the step of applying the coating material 39 is shown in Fig. 50A. The coating material 39 is applied onto the shaping surface 20a so as not to cover the background region 92.

[0290] In the step of forming the luminance adjustment layer 30, the luminance adjustment layer 30 is formed on the shaping surface 20a and on the application matter 39. An example of the step of forming the luminance adjustment layer 30 is shown in Fig. 50B. As an example, the luminance adjustment layer 30 is formed on the shaping surface 20a in the background region 92 so as to be in direct contact with the shaping surface 20a of the shaping layer 20. In the object region 91, the luminance adjustment layer 30 is formed on the application matter 39.

[0291] In the process of removing the luminance adjustment layer 30, the application material 39 is removed from the shaping surface 20a, thereby removing the luminance adjustment layer 30 from the shaping surface 20a in the object region 91. An example of the process of removing the luminance adjustment layer 30 is shown in FIG. 50C. As an example, in the object region 91, the luminance adjustment layer 30 is formed on the application material 39. Therefore, in the object region 91, the luminance adjustment layer 30 on the application material 39 can also be removed by removing the application material 39. In the background region 92, there is no application material 39 between the luminance adjustment layer 30 and the shaping layer 20. Therefore, the luminance adjustment layer 30 formed on the shaping surface 20a in the background region 92 is not removed by removing the application material 39, and remains on the shaping surface 20a. As described above, the luminance adjustment layer 30 can be removed from the object region 91 while leaving the luminance adjustment layer 30 in the background region 92.

[0292] After the step of removing the brightness adjustment layer 30, a step of forming the additional brightness adjustment layer 36 is performed. As described above, when the brightness adjustment layer 30 formed on the shaping surface 20a is removed in the object region 91, the additional brightness adjustment layer 36 is formed on the shaping surface 20a so as to cover at least the object region 91 on the shaping surface 20a. As an example, the additional brightness adjustment layer 36 is formed on the brightness adjustment layer 30 in the background region 92 and on the shaping surface 20a in the object region 91. When manufacturing the decorative laminate 10 shown in FIG. 49, a colored layer 36a is prepared as the additional brightness adjustment layer 36. This allows the decorative laminate 10 shown in FIG. 49 to be manufactured. In the example shown in FIG. 49, the colored layer 36a is formed on the shaping surface 20a in the object region 91 so as to directly contact the shaping surface 20a of the shaping layer 20.

[0293] When manufacturing a decorative laminate 10 in which the brightness adjustment layer 30 is formed on the imprinting surface 20a in the background region 92 and the brightness adjustment layer 30 is not formed on the imprinting surface 20a in the object region 91, a reflective layer 36b may be formed on the imprinting surface 20a as the additional brightness adjustment layer 36. In this case, in the process of forming the additional brightness adjustment layer 36, the reflective layer 36b is formed on the imprinting surface 20a so as to cover at least the object region 91 on the imprinting surface 20a. In this case, although not shown, the process of forming the additional brightness adjustment layer 36 can form the reflective layer 36b on the imprinting surface 20a in the object region 91 so as to directly contact the imprinting surface 20a of the imprinting layer 20. The process of forming the additional brightness adjustment layer 36 can form the reflective layer 36b on the imprinting surface 20a in the object region 91 while forming the brightness adjustment layer 30 on the imprinting surface 20a in the background region 92.

[0294] According to the manufacturing method of the decorative laminate 10 of the seventh modification, the brightness adjustment layer 30 can be formed on the shaping surface 20a in the object region 91, while the brightness adjustment layer 30 can be removed from the background region 92. In particular, the brightness adjustment layer 30 can be formed on the shaping surface 20a in the object region 91, while the additional brightness adjustment layer 36 can be formed on the shaping surface 20a in the background region 92. For example, as shown in FIG. 47, the colored layer 36a can be formed on the shaping surface 20a in the background region 92, while the reflective layer 30b can be formed on the shaping surface 20a in the object region 91. This makes it possible to make the object region 91 and the background region 92 look different depending on whether or not the reflective layer 30b is present. For example, the metallic luster is expressed by the reflective layer 30b containing a metallic material in the object region 91, and the background region 92 is an inconspicuous color, so that the object 90 can be made to look clearer. According to the manufacturing method of the decorative laminate 10 of the seventh modification, as shown in FIG. 48D, the reflective layer 36b can be formed as the additional brightness adjustment layer 36 on the shaping surface 20a in the background region 92, and the reflective layer 30b can be formed on the shaping surface 20a in the object region 91. This allows the appearance of the object region 91 and the background region 92 to be different by making the materials or forming methods of the reflective layer 30b and the reflective layer 36b different. For example, by making the materials of the reflective layer 30b and the reflective layer 36b different, the reflectance of the reflective layer 30b can be made larger than the reflectance of the reflective layer 36b. In this case, the light is reflected more strongly in the object region 91 than in the background region 92, so that the object 90 can be made to look clearer. According to the manufacturing method of the decorative laminate 10 of the seventh modification, the brightness adjustment layer 30 can be formed on the shaping surface 20a in the background region 92, while the brightness adjustment layer 30 can be removed from the object region 91. In particular, the additional brightness adjustment layer 36 can be formed on the imprinting surface 20a in the object region 91, while the brightness adjustment layer 30 can be formed on the imprinting surface 20a in the background region 92. For example, as shown in Fig. 49, the colored layer 36a can be formed on the imprinting surface 20a in the object region 91, while the reflective layer 30b can be formed on the imprinting surface 20a in the background region 92.According to the manufacturing method of the decorative laminate 10 of the seventh modification, although not shown, a reflective layer 36b can be formed as an additional brightness adjustment layer 36 on the shaping surface 20a in the object region 91, and a reflective layer 30b can be formed on the shaping surface 20a in the background region 92. In this way, according to the decorative laminate 10 of the seventh modification and the manufacturing method of the decorative laminate 10, more diverse design expressions can be realized.

[0295] <Modification 8: Modification of Decorative Member> The shape of the decorative member 3 is not particularly limited. In other words, the shape of the molded portion 65 to which the decorative laminate 10 is applied is not particularly limited. For example, as shown in FIG. 51, the decorative member 3 may include a curved surface 69. More specifically, the molded portion 65 may include a curved surface 69 corresponding to the curved surface 3c of the decorative member 3, and the decorative laminate 10 may cover the curved surface 69 of the molded portion 65. By the decorative laminate 10 covering the curved surface 69, an observer who observes the curved surface 3c of the decorative member 3 can grasp the change in the optical action of the decorative laminate 10 according to the change in the angle of incidence of light to the decorative laminate 10 without moving the observer to the decorative member 3. In other words, since the angle of incidence of light with respect to the decorative laminate 10 varies depending on the location on the curved surface 3c of the decorative member 3, an observer observing the curved surface 3c of the decorative member 3 can sense the movement of the reflected light from the decorative laminate 10 by simply moving his or her line of sight, similar to the case of observing a flat decorative laminate 10 while changing its inclination. From the viewpoint of effectively grasping the change in the optical action of the decorative laminate 10, the radius of curvature of the curved surface of the decorative member 3 (hence, the curved surface of the molded portion 65) is preferably 250 mm or more, and more preferably 100 mm or more.

[0296] In the above-mentioned specific example, the decorative laminate 10 covers the front side surface 66 of the molded portion 65, but the present invention is not limited to this example. Although not shown, the decorative laminate 10 may cover the back side surface 67 of the molded portion 65. In this case, in the decorative member 3, the decorative laminate 10 and the molded portion 65 may be arranged such that the back side surface 67 of the molded portion 65 and the front side surface 11 of the decorative laminate 10 face each other.

[0297] According to the embodiment or its modification described above, the decorative laminate 10 includes an object region 91 that displays an object 90, and a background region 92 located around the object region 91. The decorative laminate 10 includes a shaping layer 20 that extends across the object region 91 and the background region 92. The shaping layer 20 has a shaping surface 20a on which a relief structure 25 is formed. The decorative laminate 10 includes at least one unit optical element 13 that reflects, refracts, and / or diffracts incident light according to the relief structure 25. The shaping surface 20a of the unit optical element 13 includes a plurality of inclined surfaces 26A aligned in a direction toward a reference line extending along the normal direction of the decorative laminate 10 and inclined toward the reference line, and a plurality of connecting surfaces 26B that connect adjacent inclined surfaces 26A. The angle of the inclined surface 26A with respect to the normal direction is greater than the angle of the connecting surface 26B connected to the inclined surface 26A with respect to the normal direction. The unit optical elements 13 are formed in at least a part of at least one of the background region 92 and the object region 91. According to such a decorative laminate 10, in the decorative member 3 or the decorative laminate 10 that displays the object 90, a design expression that has not been achieved in the past can be realized.

[0298] According to the embodiment or its modified example described above, the inclined surfaces 26A are lens surfaces, and the connecting surfaces 26B are rise surfaces, which allows the unit optical element 13 to function as a lens.

[0299] According to the embodiment or its modification described above, the shaping surface 20a is covered with a single covering layer in the object region 91 and the background region 92. Even in the case of the decorative laminate 10 in which the shaping surface 20a is covered with a single covering layer, by providing the unit optical elements 13, a rich design expression can be realized in the decorative member 3 or the decorative laminate 10 displaying the object 90. For example, by providing the unit optical elements 13 in either the object region 91 or the background region 92, the design displayed in the object region 91 can be made different from the design displayed in the background region 92. By making the unit optical elements 13 provided in the object region 91 and the unit optical elements 13 provided in the background region 92 different from each other, the design displayed in the object region 91 can be made different from the design displayed in the background region 92.

[0300] According to the embodiment or its modified example described above, the object region 91 divides the background region 92 into a plurality of regions. Such a decorative laminate 10 is suitable for manufacturing by the manufacturing method of the decorative laminate 10 including the above-mentioned step of producing the matrix 110 and the step of forming the shaping mold 100.

[0301] According to the embodiment or its modified example described above, the decorative laminate 10 has a plurality of unit optical elements 13. The plurality of unit optical elements 13 are formed in the background region 92. Such a decorative laminate 10 can realize a design expression that has not been seen before. For example, it is possible to make the observer feel as if the background region 92 is located deeper than the object region 91. This gives the observer the impression that the object 90 stands out from the background region 92.

[0302] According to the embodiment or its modified example described above, the decorative laminate 10 has a plurality of unit optical elements 13. The plurality of unit optical elements 13 are formed in the object region 91. According to such a decorative laminate 10, a design expression not seen in the past can be realized in the object region 91. For example, it is possible to give the observer an impression that the background region 92 stands out from the object 90. As another example, it is possible to give the observer an impression that the object region 91 protrudes from the background region 92. As another example, it is possible to display a desired three-dimensional shape in a pseudo manner in the object region 91.

[0303] According to the embodiment or its modified example described above, the unit optical element 13 is formed in the object region 91. The inclined surfaces 26A and the connecting surfaces 26B are arranged such that the boundary 26C between the adjacent inclined surfaces 26A and the connecting surfaces 26B extends along the contour 94 of the object region 91 in a plan view. According to such a decorative laminate 10, a design expression not seen in the past can be realized in the object region 91. For example, the shape of the contour 94 of the object region 91 can be accentuated. As another example, a three-dimensional effect can be imparted to the displayed object 90. As an example, the object 90 can be given the impression of protruding from the background region 92. This can leave a strong impression of the object 90 on the observer.

[0304] According to the embodiment or its modified example described above, the unit optical elements 13 are formed in a part of the region 91A in the object region 91 that is adjacent to the contour 94 of the object region 91. According to such a decorative laminate 10, a design expression not seen before can be realized in the object region 91. For example, the shape of the contour 94 of the object region 91 can be accentuated. As another example, a three-dimensional effect can be imparted to the displayed object 90. This can make a strong impression of the object 90 on the observer.

[0305] According to the embodiment or its modification described above, the unit optical element 13 is formed in the object region 91. The object region 91 has a first object region 91D adjacent to the contour 94 of the object region 91 and a second object region 91E surrounded by the first object region 91D. The unit optical element 13 has a first uneven structure 251 formed in the first object region 91D and a second uneven structure 252 formed in the second object region 91E. The angle of the inclined surfaces 26A included in the first uneven structure 251 with respect to the normal direction of the decorative laminate 10 is constant. The angle of the inclined surfaces 26A included in the second uneven structure 252 with respect to the normal direction of the decorative laminate 10 is different from each other. According to such a decorative laminate 10, a design expression that has not been seen in the past can be realized in the object region 91. For example, it is possible to give a different impression to an observer who observes the object region 91 between the first object region 91D and the second object region 91E. More specifically, the first object region 91D can give the impression that the second object region 91E significantly protrudes from the background region 92. The second object region 91E can give the impression that the object 90 has a rounded shape in the second object region 91E.

[0306] According to the embodiment or its modified example described above, the unit optical element 13 includes a first region. The inclined surfaces 26A include a plurality of first inclined surfaces 26A1 arranged in the first region 234 and aligned in a direction toward a first reference line L1 extending along a normal direction of the decorative laminate 10 and inclined toward the first reference line L1. The connecting surfaces 26B include a plurality of first connecting surfaces 26B1 connecting adjacent first inclined surfaces 26A1. According to such a decorative laminate 10, a design expression not seen in the past can be realized.

[0307] According to the embodiment or its modification described above, the first inclined surfaces 26A1 are shaped as side surfaces or parts of the side surfaces at different height positions of the first pyramid or the first frustum. According to such a decorative laminate 10, the first region 234 can function as a lens shaped like the first pyramid or the first frustum.

[0308] According to the embodiment or its modification described above, the unit optical element 13 includes the second region 235 adjacent to the first region 234 in the direction in which the first inclined surfaces 26A1 are arranged. In the second region 235, the shaping surface 20a is a flat surface or a curved surface. According to such a decorative laminate 10, it is possible to realize a design expression that has not been seen before.

[0309] According to the embodiment or its modification described above, the unit optical element 13 includes the second region 235 adjacent to the first region 234 in the direction in which the first inclined surfaces 26A1 are arranged. The second region 235 includes a plurality of second inclined surfaces 26A2 forming a Fresnel lens structure and a plurality of second connecting surfaces 26B2 connecting the adjacent second inclined surfaces 26A2. According to such a decorative laminate 10, it is possible to realize a design expression that has not been seen before.

[0310] According to the embodiment or its modification described above, the unit optical element 13 includes a second region 235 adjacent to the first region 234 in the direction in which the first inclined surfaces 26A1 are arranged. The second region 235 includes a plurality of second inclined surfaces 26A2 arranged in a direction toward the second reference line L2 extending along the normal direction and inclined toward the second reference line L2, and a plurality of second connection surfaces 26B2 connecting the adjacent second inclined surfaces 26A2. According to such a decorative laminate 10, a design expression not seen in the past can be realized.

[0311] According to the embodiment or its modification described above, the second inclined surfaces 26A2 are formed as side surfaces at different height positions of the second pyramid or the second frustum, or as parts of the side surfaces. With such a decorative laminate 10, it is possible to realize a design expression that has not been seen before.

[0312] According to the embodiment or its modification described above, the first inclined surfaces 26A1 are shaped as side surfaces at different height positions of the first frustum, or as parts of the side surfaces. The second inclined surfaces 26A2 are shaped as side surfaces at different height positions of the second pyramid or the second frustum, or as parts of the side surfaces. The shape of the bottom surface of the first frustum and the shape of the bottom surface of the second pyramid or the second frustum are different from each other. With such a decorative laminate 10, it is possible to realize a design expression that has not been seen before.

[0313] According to the embodiment or its modified example described above, the inclined surfaces 26A form a Fresnel lens structure. With such a decorative laminate 10, it is possible to realize a design expression that has not been seen before.

[0314] According to the embodiment or its modified example described above, the transfer sheet 70 includes a transfer base material (base material 72) and the above-mentioned decorative laminate 10. Such a transfer sheet 70 can realize a design expression that has not been achieved in the past.

[0315] According to the embodiment or the modified example thereof described above, the decorative member 3 includes the above-mentioned decorative laminate 10. Such a decorative member 3 can realize a design expression that has not been seen before.

[0316] According to the embodiment or the modified example thereof described above, the moving body 1 includes the above-mentioned decorative laminate 10. With such a moving body 1, it is possible to realize a design expression that has not been seen before.

[0317] According to the embodiment or its modification described above, in the manufacturing method of the decorative laminate 10 described above, the unit optical element 13 is formed in the background region 92. The manufacturing method of the decorative laminate 10 includes a step of applying a coating material 39 on the shaping surface 20a so as to cover the background region 92, a step of forming a reflective layer 30b on the shaping surface 20a and the coating material 39, and a step of removing the reflective layer 30b from the shaping surface 20a in the background region 92 by removing the coating material 39 from the shaping surface 20a.
