[0057] 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.

[0058] In order to clarify the directional relationship between the drawings, common directions are indicated in several drawings by arrows with common symbols. An arrow pointing into the paper in a direction perpendicular to the paper surface of the drawing is indicated by a symbol of a cross in a circle, as shown in Fig. 1B. Furthermore, an arrow pointing toward the viewer in a direction perpendicular to the paper surface of the drawing is indicated by a symbol of a dot in a circle, as shown in Fig. 3.

[0059] As used in this specification, terms specifying shapes and geometric conditions as well as the degree thereof, such as "parallel," "perpendicular," "same," and the like, 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.

[0060] 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.

[0061] 1A, 1B, 2A, 3 to 14 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.

[0062] In the examples shown in Fig. 1A, Fig. 1B, and Fig. 2A, the decorative member 3 is used in a moving body 1. In the illustrated examples, the decorative member 3 is installed on a front panel 2 of the moving body 1. 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.

[0063] 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 also be used in the interior body of a moving body. The decorative member 3 and the decorative laminate 10 can also be applied to, for example, 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.

[0064] <<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. However, this is not limited to this example, and the front side surface 3a and the back side surface 3b may be curved.

[0065] In the example shown in Fig. 1B, the decorative member 3 has a decorative laminate 10 and a 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.

[0066] 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.

[0067] 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.

[0068] 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).

[0069] 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 3a described later.

[0070] As used herein, "transparent" means that the visible light transmittance, specified as the average value of the transmittance at each wavelength when measured using a spectrophotometer (Shimadzu Corporation's "UV-3100PC", compliant with JIS K 0115) within the measurement wavelength range of 380 nm to 780 nm, is 50% or more, and preferably 80% or more.

[0071] 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.

[0072] The sensor 5 faces the back side surface 3b of the decorative member 3. In the example shown in FIG. 1B, 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.

[0073] <<Decorative laminate>> Next, the decorative laminate 10 will be described in more detail. As shown in FIG. 2A and FIG. 4, the decorative laminate 10 includes a shaping layer 20 and a brightness adjustment layer 30. As shown in FIG. 4, the shaping layer 20 has a shaping surface 20a on which a concave-convex structure 25 is formed, and a non-shaping surface 20b on the opposite side of the shaping surface 20a. The brightness adjustment layer 30 covers the shaping surface 20a. As shown in FIG. 3, the decorative laminate 10 has 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 shaping 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. As a result, the design of the decorative laminate 10 is improved. In the illustrated example, the decorative laminate 10 has a plurality of unit optical elements 13. This makes it possible to impart a complex design to the decorative laminate 10 by combining a plurality of unit optical elements 13 .

[0074] The decorative laminate 10 may include other layers. For example, in the example shown in FIG. 2A and FIG. 4, the decorative laminate 10 includes a bonding layer 35 and a functional layer 37. In this example, the bonding layer 35, 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 to 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 35 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. Of course, the molding layer 20 may form the front side surface 11 of the decorative laminate 10. Also, the brightness adjustment layer 30 may form the back side surface 12 of the decorative laminate 10.

[0075] <Shaping layer> First, the shaping layer 20 will be described. In the example shown in FIG. 3, the shaping layer 20 has at least one unit shaping element 23. In the illustrated example, the shaping layer 20 has a plurality of unit shaping elements 23. 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 thereon. The concave-convex structure 25 can be formed by shaping the shaping layer 20 using a shaping mold 100 described later.

[0076] The shaping surface 20a has the uneven structure 25, so that the light incident on the unit optical element 13 is subjected to an optical action (reflection, refraction, and / or diffraction) according to the uneven structure 25. In the illustrated example, the uneven structure 25 is determined so as to converge and / or diverge the parallel light incident on the front side surface 11 of the decorative laminate 10. The shaping layer 20 includes the unit shaping element 23 having the uneven structure 25, so that the decorative laminate 10 can express a rich three-dimensional effect that is greater than its thickness. In addition, the shaping layer 20 includes a plurality of unit shaping elements 23, so that a plurality of unit optical elements 13 can be formed in the decorative laminate 10. In this embodiment, each uneven structure 25 is configured so that each unit optical element 13 provides the same optical action as a convex lens or an optical action corresponding to the optical action to the light incident on the unit optical element 13. The optical action corresponding to the same optical action as a convex lens means, for example, an optical action similar to a convex mirror. As a result, the unit optical element 13 exerts an optical function similar to that of a convex lens or an optical function corresponding to that optical function. As a result, the decorative laminate 10 can express a design with a sense of depth greater than the actual thickness of the decorative laminate 10, and can express a three-dimensional effect. And, a rich design expression with a sense of luxury is possible. Of course, each uneven structure 25 may be configured so that each unit optical element 13 exerts an optical action similar to that of a concave lens or an optical action corresponding to that optical action on the light incident on the front side surface 11 of the decorative laminate 10. In this case, too, the decorative laminate 10 can express a design with a sense of depth greater than the actual thickness of the decorative laminate 10, and can express a three-dimensional effect. As a result, a rich design expression with a sense of luxury is possible.

[0077] 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.

[0078] In the example shown in FIG. 3, the multiple unit shaping elements 23 (multiple unit optical elements 13) have the same shape in plan view. The multiple unit shaping elements 23 are circular in plan view. The multiple unit shaping elements 23 are regularly arranged. The multiple unit shaping elements 23 are squarely arranged. However, this is not limited to the example. The multiple unit shaping elements 23 may have different shapes from each other. Each unit shaping element 23 may have a shape other than a circle. For example, each unit shaping element 23 may be a polygonal shape such as a triangular shape, a rectangular shape, a pentagonal shape, a hexagonal shape, or an octagonal shape. The multiple unit shaping elements 23 may have a shape other than a polygonal shape. That is, the unit shaping element 23 may include a curved portion or a portion extending in an arc shape. The unit shaping element 23 may have any shape, such as a semicircular shape, an elliptical shape, a sector shape, a crescent shape, a heart shape, or a letter shape. The unit shaping elements 23 may be arranged in an irregular array. Furthermore, although not shown, each unit shaping element 23 may have a shape in which the above-mentioned shapes are overlapped with each other.

[0079] As shown in FIG. 3 and FIG. 4, each unit optical element 13 has a first region 131. In this embodiment, the shaping surface 20a includes a plurality of first inclined surfaces 26A inclined with respect to the normal direction Dn of the decorative laminate 10 in the first region 131, and a plurality of first connecting surfaces 26B connecting adjacent first inclined surfaces 26A. The first region 131 includes at least 10 first inclined surfaces 26A. The number of first inclined surfaces 26A included in the first region 131 may be 10 or more, 50 or more, 100 or more, or 200 or more. In the example shown in FIG. 3 and FIG. 4, the first inclined surface 26A is located close to the reference line. Therefore, in the example shown in FIG. 3 and FIG. 4, the first inclined surface 26A is also referred to as a "reference line-near inclined surface". As will be described later, in the examples shown in FIGS. 19 to 21 and 25E to 25G, the first tilting surface 26A is also referred to as the "reference line adjacent tilting surface."

[0080] In the example shown in FIG. 3 and FIG. 4, the first inclined surfaces 26A correspond to a plurality of lens surfaces obtained by dividing a continuous convex lens surface along a surface perpendicular to the thickness direction. The first connecting surface 26B corresponds to a rise surface connecting adjacent lens surfaces. According to such a concave-convex structure 25, it is possible to effectively suppress an increase in the thickness of the decorative laminate 10 caused by making the unit optical elements 13 function as convex lenses. For example, as in the illustrated example, when the decorative member 3 is used for a 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 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.

[0081] In the illustrated example, the first inclined surface 26A extends along the contour of the unit shaping element 23 (unit optical element 13). This makes it possible to effectively highlight the contour of each unit optical element 13. Also, in the illustrated example, a gap region 24 is formed between adjacent unit shaping elements 23. This also makes it possible to effectively highlight the contour of each unit optical element 13.

[0082] In the example shown in FIG. 3 to FIG. 5, the first region 131 exerts an optical function similar to that of the cone-shaped lens (axicon lens) shown in FIG. 6 or an optical function corresponding to the optical function. The first inclined surfaces 26A correspond to the surfaces obtained by dividing the side surface of the cone along a cross section perpendicular to the height direction. The first region 131 is a region extending from the inclined surface 26Ao located on the outermost side of the first inclined surfaces 26A to the inclined surface 26Ac located on the innermost side of the first inclined surfaces 26A when viewed in the normal direction Dn of the decorative laminate 10. The first inclined surfaces 26A are arranged in a direction toward the first reference line L1 extending along the normal direction Dn of the decorative laminate 10. Here, the normal direction Dn coincides with the Z direction Dz. The first reference line L1 coincides with the perpendicular line of the cone (a line perpendicularly drawn from the apex of the cone to the bottom surface).

[0083] The multiple first inclined surfaces 26A have the shape of a side surface at different height positions of a cone shown in Fig. 6. For example, the shape of the first inclined surface 26Ac located at the center among the multiple first inclined surfaces 26A is the shape of a side surface at a height position including the apex of the cone shown in Fig. 6. Also, the shape of the first inclined surface 26Ao located at the outermost position among the multiple first inclined surfaces 26A is the shape of a side surface at a height position connecting to the bottom surface of the cone shown in Fig. 6. The inclined surface 26Ac is the inclined surface closest to the first reference line L1 among the multiple first inclined surfaces 26A.

[0084] In the example shown in Fig. 4, the multiple first tilting surfaces 26A are formed by dividing the side surface of a cone into concentric circles centered on the first reference line L1. In the example shown in Fig. 3, the multiple first tilting surfaces 26A are similar to each other. As shown in Fig. 5, the first tilting surfaces 26A are represented by straight lines in a cross section of the unit optical element 13 along the direction in which the multiple first tilting surfaces 26A are arranged.

[0085] In the example shown in Fig. 4 and Fig. 5, the first region 131 exhibits an optical function similar to that of a lens in the shape of a right cone shown in Fig. 6 or an optical function corresponding to that optical function, but is not limited thereto. The first region 131 may exhibit an optical function similar to that of a lens in the shape of an oblique cone as shown in Fig. 7 or an optical function corresponding to that optical function. In this case, the uneven structure 25 of the first region 131 is formed as shown by the dashed line in Fig. 3. Fig. 8A and Fig. 8B are diagrams showing a cross section of the decorative laminate 10 taken along the line VIII-VIII in Fig. 3. In addition, the first region 131 may exhibit an optical function similar to that of a lens in the shape of a cone whose bottom surface is elliptical or an optical function corresponding to that optical function.

[0086] In this specification, the angle θA of the first inclined surface 26A with respect to the normal direction Dn of the decorative laminate 10 (hereinafter also referred to as the "first inclined surface angle") is measured as the angle of the straight line LA connecting the top and bottom of each first inclined surface 26A with respect to the normal direction Dn in the cross section of the molding layer 20 along the direction in which the multiple first inclined surfaces 26A are arranged, as shown in Figures 5 and 8B. Similarly, in this specification, the angle θB of the first connecting surface 26B with respect to the normal direction Dn of the decorative laminate 10 (hereinafter also referred to as the "first connecting surface angle") is measured as the angle of the straight line LB connecting the top and bottom of each first connecting surface 26B with respect to the normal direction Dn in the cross section of the molding layer 20 along the direction in which the multiple first connecting surfaces 26B are arranged, as shown in Figures 5 and 8B. A first inclination surface angle θA of each first inclination surface 26A is larger than a first connection surface angle θB of a first connection surface 26B connected to the first inclination surface 26A.

[0087] 3, the multiple first tilting surfaces 26A extend to surround the first reference line L1. Therefore, as shown in FIGS. 4 and 8A, in a cross section of the unit optical element 13 along the direction in which the multiple first tilting surfaces 26A are arranged, the multiple first tilting surfaces 26A are present on both sides of the first reference line L1.

[0088] In order for the first region 131 to exhibit an optical function similar to that of a conical lens or an optical function corresponding to the optical function, the unit shaping element 23 has the following characteristics. That is, as described above, the multiple first inclined surfaces 26A are arranged in a direction toward the first reference line L1 extending along the normal direction Dn of the decorative laminate 10. Also, the multiple first inclined surfaces 26A are inclined toward the first reference line L1. In the example shown in FIG. 4 and FIG. 8A, in the above cross section, the first inclined surface 26A is inclined in a first direction D1 with respect to the normal direction Dn on one side of the first reference line L1 (for example, the left side in FIG. 4 and FIG. 8A), and is inclined in a second direction D2 opposite to the first direction D1 with respect to the normal direction Dn on the other side of the first reference line L1 (for example, the right side in FIG. 4 and FIG. 8A).

[0089] As an additional feature, the unit shaping element 23 has the following feature. That is, as shown in Fig. 5 and Fig. 8B, in a cross section of the unit optical element 13 along the direction in which the multiple first inclined surfaces 26A are arranged, the standard deviation of the pitch WA1 of the multiple first inclined surfaces 26A on one side of the first reference line L1 (for example, the left side in Fig. 4 and Fig. 8A) is 5 μm or less. The pitches WA1 may be equal to each other. Also, on one side of the first reference line L1, the standard deviation of the heights H26 (dimension in the Z direction Dz) of the multiple first inclined surfaces 26A is 1 μm or less. The heights H26 may be equal to each other. Furthermore, as shown in FIG. 4 and FIG. 8A, when a plurality of first inclined surfaces 26A are present on the other side of the first reference line L1 (for example, on the right side of FIG. 4 and FIG. 8A) in the above cross section, the standard deviation of the pitch WA2 of the first inclined surfaces 26A on the other side of the first reference line L1 is 5 μm or less. The pitches WA2 may be equal to each other. Also, the standard deviation of the heights H26 of the plurality of first inclined surfaces 26A on the other side of the first reference line L1 is 1 μm or less. The heights H26 may be equal to each other. Here, the average value of the pitch WA1 and the average value of the pitch WA2 may be equal to each other (see FIG. 4) or may be different from each other (see FIG. 8A).

[0090] Alternatively, instead of or in addition to the above additional features, the unit shaping element 23 has the following additional features. That is, in the above cross section, the difference between the maximum value and the minimum value of the first inclined surface angle θA of the first inclined surface 26A on one side of the first reference line L1 is 1° or less. Furthermore, as shown in Figs. 4 and 8A, in the above cross section, when a plurality of first inclined surfaces 26A exist on the other side of the first reference line L1, the difference between the maximum value and the minimum value of the first inclined surface angle θA of the first inclined surface 26A on the other side of the first reference line L1 is 1° or less. The average value of the first inclined surface angle θA on one side of the first reference line L1 and the average value of the first inclined surface angle θA on the other side of the first reference line L1 may be equal to each other (see Fig. 4) or may be different from each other (see Fig. 8A).

[0091] The first connecting surface angle θB can be set appropriately. In the illustrated example, in consideration of forming the concave-convex structure 25 with high accuracy and the adhesion between the shaping surface 20a and the brightness adjustment layer 30, the first connecting surface angle θB is preferably 15° or more, and more preferably 25° or more. In addition, in consideration of ensuring a sufficient area of ​​the first inclined surface 26A, the first connecting surface angle θB is preferably 55° or less, and more preferably 45° or less. Therefore, the first connecting surface angle θB is preferably 15° or more and 55° or less.

[0092] 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. In the illustrated example, the heights H26 of the multiple first inclined surfaces 26A or the multiple first connecting surfaces 26B of the concave-convex structure 25 are equal to each other. Therefore, the height H25 is equal to the height H26.

[0093] 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.

[0094] In order to suppress the occurrence of rainbow light on the front side surface 11 of the decorative laminate 10, the pitches WA1 and WA2 of the first inclined surfaces 26A are 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 pitches WA1 and WA2 of the first inclined surfaces 26A are preferably 100 μm or less, more preferably 50 μm or less, and even more preferably 20 μm or less. Therefore, the pitches WA1 and WA2 of the first inclined surfaces 26A are preferably 7.5 μm or more and 100 μm or less.

[0095] 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.

[0096] When it is desired to generate rainbow light on the front side surface 11 of the decorative laminate 10, the pitches WA1, WA2 of the first inclined surfaces 26A are preferably less than 7.5 μm, more preferably 5 μm or less, and even more preferably 2 μm or less.

[0097] 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 pitches WA1 and WA2 of the concave-convex structure 25 are preferably 2 μm or more, more preferably 4 μm or more, and even more preferably 8 μm or more.

[0098] The inclined surface angle θA, the connecting surface angle θB, the height H25, and the pitches WA1 and WA2 can be measured by observing an image of the cross section of the decorative laminate 10 using a scanning electron microscope. The reference line-proximate inclined surface of the unit optical element 13 refers to the 10 inclined surfaces closest to a reference line among the multiple inclined surfaces aligned in the direction toward a reference line and inclined toward the reference line in the unit optical element 13. The standard deviation of the pitch of the reference line-proximate inclined surface on one side of the reference line is the standard deviation of the pitch of the 10 inclined 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 multiple inclined surfaces are aligned. The standard deviation of the height of the reference line-proximate inclined surface on one side of the reference line is the standard deviation of the height of the 10 inclined 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 multiple inclined surfaces are aligned. In addition, the standard deviation of the inclination surface angle on one side of the reference line of the reference line-nearby inclination surface is the standard deviation of the inclination surface angle on one side of the reference line of the 10 inclination surfaces closest to the reference line in a certain cross section of the unit optical element 13 along the direction in which the multiple inclination surfaces are arranged.

[0099] As shown in FIG. 4 and FIG. 8A, when the non-shaping surface 20b of the shaping layer 20 faces the front side surface 3a of the decorative member 3, in order to effectively suppress the risk of the concave-convex structure 25 being damaged by an external force applied to the front side surface 3a of the decorative member 3, the ratio (T20 / H25) of the thickness T20 of the shaping layer 20 to the height H25 of the concave-convex structure 25 is preferably 1.5 or more, more preferably 1.8 or more, and even more preferably 2.5 or more. In addition, when T20 / H25 is 1.5 or more, the shaping layer 20 has a sufficient thickness, so that the concave-convex structure 25 can be formed with higher accuracy, particularly using the shaping mold 100. In addition, from the viewpoint of suppressing an increase in the thickness of the decorative laminate 10 due to an increase in the thickness of the shaping layer 20, T20 / H25 is preferably 8.0 or less, more preferably 6.0 or less, and even more preferably 4.0 or less. Therefore, T20 / H25 is preferably 1.5 or more and 8.0 or less. In this specification, "thickness T20 of the shaping layer" means the maximum value of the distance (dimension in the Z direction Dz) T26 (see FIG. 5) between the non-shaping surface 20b and the top of the inclined surface 26A or the connecting surface 26B. In the illustrated example, the distance T26 between the non-shaping surface 20b and the tops of the multiple inclined surfaces 26A or the multiple connecting surfaces 26B is uniform, and the thickness T20 is equal to the distance T26.

[0100] 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 that may have a polymerizable unsaturated group and a (meth)acrylic polymerizable monomer or oligomer. In this specification, the expression (meth)acrylic means one or both of "acrylic" and "methacrylic". The mass ratio of the acrylic resin that may have a polymerizable unsaturated group / (meth)acrylic polymerizable monomer or oligomer in the ultraviolet-curable resin is preferably 35 / 65 or more and 95 / 5 or less, and more preferably 70 / 30 or more and 90 / 10 or less. The shape-imparting layer 20 formed in this manner is flexible and extensible. Therefore, when the decorative laminate 10 is curved or stretched along the surface of the molding portion 65, the shaping layer 20 can be curved or stretched as desired. In other words, there is little risk that the shaping layer 20 will hinder the curving or stretching of the decorative laminate 10.

[0101] In the illustrated example, the molding layer 20 is transparent so that the brightness adjusting layer 30 can be seen from the front side surface 11. In the illustrated example, the plurality of concave-convex structures 25 of the plurality of unit molding elements 23 included in the molding layer 20 are integrally molded without seams (see FIGS. 4 and 8A).

[0102] <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.

[0103] In the illustrated example, the brightness adjustment layer 30 is provided to adjust the reflectance of visible light measured on the front 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 reflection interface between the shaping surface 20a and the brightness adjustment layer 30, and adjusts the reflectance of visible light measured on the front 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 examples shown in FIG. 4 and FIG. 8A, the brightness adjustment layer 30 also functions as a flattening layer that fills the unevenness of the shaping surface 20a.

[0104] 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 between the shaping surface 20a and the brightness adjustment layer 30. The colored layer 30a can also impart a desired color to the decorative laminate 10. A material that is a mixture of a pigment or dye and a resin 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.

[0105] 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".

[0106] 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.

[0107] 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.

[0108] 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.

[0109] 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.

[0110] 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.

[0111] 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.

[0112] 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.

[0113] 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.

[0114] 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.

[0115] 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.

[0116] 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.

[0117] Alternatively, the colored layer 30a may be black by containing the above-mentioned pigments and dyes other than the black pigment and black dye.

[0118] 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.

[0119] <Joining layer> The bonding layer 35 bonds (adheses, sticks, or heat seals) other layers of the decorative laminate 10 to the molded portion 65. As a material for forming the bonding layer 35, a thermoplastic resin, a (meth)acrylic acid ester copolymer, or the like can be used. The thermoplastic resin is not particularly limited, and for example, an acrylic resin, a vinyl chloride-vinyl acetate copolymer, a polyamide resin, a polyester resin, a chlorinated polypropylene, a chlorinated rubber, a urethane resin, an epoxy resin, a styrene resin, or the like can be used. These resins may be used alone or in combination of two or more kinds.

[0120] <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, an anti-reflection function, an anti-glare function, an antistatic function, and an antifouling 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.

[0121] 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.

[0122] <Reflectance of Decorative Laminate> Next, the reflectance of the decorative laminate 10 of the present embodiment will be described. According to the findings of the present inventors, in the decorative laminate 10 having the colored layer 30a, the total light reflectance (R SCI ) and diffuse light reflectance (R SCE ), the thickness of the decorative laminate 10 can be effectively made to look thicker than the actual thickness. Specifically, the shaping surface 20a or the brightness adjustment layer 30 can be made to look as if it is located deeper than the actual position of the shaping surface 20a or the brightness adjustment layer 30. This makes it possible to more effectively impart a rich design with a sense of luxury to the decorative laminate 10.

[0123] Here, the total light reflectance (R SCI ) and diffuse light reflectance (R SCE ) is measured under geometric condition c in accordance with JIS Z 8722:2009. SCI ) and diffuse light reflectance (R SCE ) is the reflectance Y value (Y of the tristimulus values ​​XYZ) measured using a spectrophotometer in accordance with JIS Z 8722:2009 using the SCI and SCE methods. SCI ) and diffuse light reflectance (R SCE The total light reflectance (R SCI ) and diffuse light reflectance (R SCE The measurement of colorimeter 12 is performed by pressing a spectrophotometer vertically against the front surface 11 of the decorative laminate 10 placed on a flat table. The measurement wavelength range of this spectrophotometer is 400 nm to 700 nm, and the measurement wavelength interval is 10 nm. <Measurement conditions> Mode (specular reflection processing mode): I+E (SCI+SCE) <Observation conditions> ·Color system: L * a * b * ·Color difference formula: ΔE * ab Viewing angle: 10° field of view ·Main light source: D65 <Measurement diameter / Illumination diameter> By replacing the target mask and switching the lens position, it can be set to either Φ3mm / Φ6mm or Φ8mm / Φ11mm.

[0124] The measurement diameter / illumination diameter is selected according to the dimensions of the unit optical element 13. Here, the illumination diameter is the diameter of the irradiation area of ​​the spectrophotometer, and the measurement diameter is the diameter of the measurement area C of the spectrophotometer (see FIG. 9).

[0125] In the illustrated example, when the center of the measurement area C is aligned with the geometric center of the unit optical element 13, the measurement diameter / illumination diameter is selected so that at least 40% of the unit optical element 13 falls within the measurement area C, and the total light reflectance (R SCI ) and diffuse light reflectance (R SCE ) is set. The smallest measurement diameter is selected from the selectable measurement diameters. For example, when at least 40% of the unit optical elements 13 fit within a virtual circle with a diameter of 3 mm, at least 40% of the unit optical elements 13 fit within the measurement region C regardless of whether the measurement diameter / illumination diameter is Φ3 mm / Φ6 mm or Φ8 mm / Φ11 mm, but the measurement diameter / illumination diameter is set to Φ3 mm / Φ6 mm. Also, when at least 40% of the unit optical elements 13 fit within a virtual circle with a diameter of 8 mm but do not fit within a virtual circle with a diameter of 3 mm, the measurement diameter / illumination diameter is set to Φ8 mm / Φ11 mm.

[0126] Next, as shown in FIG. 9, the position of the measurement area C of the spectrophotometer with respect to the unit optical element 13 is determined so that the center of the measurement area C of the spectrophotometer coincides with the geometric center of the unit optical element 13 in a plan view of the decorative laminate 10, and the total light reflectance (R SCI ) and diffuse light reflectance (R SCE ) is measured.

[0127] In the case where the colored layer 30a is colored with a pigment or dye, the inventors have determined that the total light reflectance (R SCI ) and diffuse reflectance (R SCE ) is the following formula: Total light reflectance (R SCI ) and diffuse light reflectance (R SCE ) is expressed as: 3%≦R SCI ≦35%, 0.15%≦R SCE ≦25%, 1.3≦R SCI / R SCE ≦15, It has been found that by adjusting the reflectance at the front surface 11 of the decorative laminate 10 so as to satisfy the above, the thickness of the decorative laminate 10 can be made to appear thicker than its actual thickness, and the color of the colored layer 30a can be perceived clearly when the decorative laminate 10 is observed.

[0128] In addition, the present inventors have found that when the colored layer 30a is colored with a black pigment or dye, the reflectance of the front surface 11 of the decorative laminate 10 can be adjusted as follows, that is, the total light reflectance (R SCI ) and diffuse reflectance (R SCE ) is the following formula: 3%≦R SCI ≦8%, 0.15%≦R SCE ≦1.2%, 4≦R SCI / R SCE ≦15, It has been discovered that by adjusting the reflectance at the front surface 11 of the decorative laminate 10 so as to satisfy the above, it is possible to make the thickness of the decorative laminate 10 appear thicker than its actual thickness and to enhance the jet black color of the decorative laminate 10.

[0129] Furthermore, the present inventors have found that when the colored layer 30a is colored with a black pigment or dye, the reflectance of the front surface 11 of the decorative laminate 10 can be adjusted as follows, that is, the total light reflectance (R SCI ) and diffuse reflectance (R SCE ) is the following formula: 4%≦R SCI ≦6%, 0.3%≦R SCE ≦0.6%, 8≦R SCI / R SCE ≦15, It has been discovered that by adjusting the reflectance of the front surface 11 of the decorative laminate 10 so as to satisfy the above, it is possible to make the thickness of the decorative laminate 10 appear much thicker than its actual thickness and to further effectively improve the jet blackness of the decorative laminate 10.

[0130] The total light reflectance (RSCI ) and diffuse reflectance (R SCE ) can be adjusted by adjusting the weight ratio (P / V) of the pigment (P) to the resin (V) contained in the colored layer 30a. More specifically, when the colored layer 30a is formed of a colorless and transparent resin and a pigment, P / V is preferably 0.2 or more, more preferably 0.5 or more, and even more preferably 0.8 or more. From the viewpoint of the durability of the colored layer 30a and its adhesion to other layers, P / V is preferably 2 or less, more preferably 1.5 or less, and even more preferably 1.2 or less. Therefore, P / V may be 0.2 or more and 2 or less.

[0131] When the luminance adjustment layer 30 is a colored layer 30a, the decorative laminate 10 may further include a concealing layer 60 described below. The concealing layer 60 forms the back surface 12 of the decorative laminate 10, or is disposed between the shape-imparting layer 20 and the luminance adjustment layer 30 and the back surface 12. In this case, a color that is a combination of the color of the luminance adjustment layer 30 and the color of the concealing layer 60 can be imparted to the decorative laminate 10.

[0132] <<Method of manufacturing decorative parts>> Next, a manufacturing method of the decorative member 3 according to the present embodiment (i.e., the decorative member 3 shown in FIG. 2A) will be described with reference to Fig. 10 to Fig. 14. Fig. 10 to Fig. 14 are cross-sectional views showing a manufacturing method of a transfer sheet 70 for transferring the decorative laminate 10 to the molding portion 65.

[0133] First, as shown in FIG. 10, 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. 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 used. A release layer may be formed on one side of the substrate 72. The release layer has a releasability that makes it easy to peel off 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 used. 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.

[0134] 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.

[0135] Next, as shown in FIG. 11, 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. 12, a mold 100 is pressed against the layer 29 to mold it. The mold 100 has projections and recesses corresponding to the projection and recess structure 25. Next, the layer 29 is irradiated with ultraviolet light to harden it. This produces a mold layer 20 in which the projection and recess 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.

[0136] The unevenness of the shaping mold 100 is determined so that the connection surface 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 connection surface 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.

[0137] Next, as shown in FIG. 13, a colored layer 30a is formed on the molding surface 20a of the mold 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 molding 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 molding 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 molding 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 35 is formed on the colored layer 30a as shown in FIG. 14. This produces the transfer sheet 70 shown in FIG. 14.

[0138] Next, the transfer sheet 70 is placed in a mold for forming the molded portion 65. Next, molten resin is introduced between the back surface 12 (i.e., the bonding layer 35) 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.

[0139] <<Manufacturing method of the molding mold for the molding layer>> Next, a method for producing the shaping mold 100 for forming the concave-convex structure 25 in the shaping layer 20 will be described.

[0140] First, a method for producing a matrix 110 for forming a shaping mold 100 will be described with reference to Fig. 15A to Fig. 15C. First, a matrix forming member 111 is prepared as shown in Fig. 15A. 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.

[0141] Next, as shown in FIG. 15B, the photosensitive layer 113 is irradiated with the 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 member 111 for forming a matrix. At this time, the intensity of the laser light R is controlled in multiple gradations of three or more tones. The intensity of the laser light R is controlled based on data representing the uneven structure 25. This data includes information regarding 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 including the gap areas 24 between these plurality of unit shaping elements 23). In addition, this uneven pattern represents the height (depth) of the unevenness to be formed on the shaping surface 20a based on the non-shaping surface 20b in multiple stages of three or more stages. Using such data, the intensity of the laser light R is controlled in multiple gradations of three or more tones. Moreover, the laser light R is irradiated at 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.

[0142] 15C, the photosensitive layer 113 is developed and a part of the photosensitive layer 113 is removed. As described above, the exposure amount of the laser light R at each position of the photosensitive layer 113 reflects the above-mentioned unevenness pattern, so that unevenness reflecting the above-mentioned unevenness pattern is formed in the developed photosensitive layer 113. In this manner, a master mold 110 having unevenness reflecting the above-mentioned unevenness pattern is produced.

[0143] 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.

[0144] Next, a method for producing the shaping mold 100 will be described with reference to Figures 16A and 16B. First, as shown in Figure 16A, a metal layer 115 is formed on the uneven surface 110a of the matrix 110. The metal layer 115 may be formed of nickel or the like by, for example, electroforming. The metal layer 115 has unevenness formed thereon that reflects the unevenness of the matrix 110 (and therefore reflects the above-mentioned uneven pattern).

[0145] Next, as shown in Fig. 16B, 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. A large shaping mold may be produced by combining a plurality of shaping molds 100 produced in this manner.

[0146] 17, by using the shaping mold 100 thus produced, a plurality of unit shaping elements 23 can be shaped in the shaping layer 20 in an intended arrangement pattern at once. At the same time, the gap regions 24 between the plurality of unit shaping elements 23 can also be shaped. 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.

[0147] Furthermore, the shaping mold 100 thus produced has a higher degree of freedom in designing the concave-convex structure 25 than a shaping mold produced using a matrix produced by conventional cutting processing. Specifically, the shapes of the inclined surface 26A and the connecting surface 26B can be freely set compared to the conventional method.

[0148] <<<Modifications>>> Next, various modified examples of this embodiment will be described with reference to Figures 18 to 35. In Figures 18 to 35, the same parts as those in the embodiment shown in Figures 1 to 14 are given the same reference numerals and detailed description thereof will be omitted.

[0149] <<Modification of uneven structure>> <First area> In the above example, the first region 131 exhibits an optical function similar to that of a conical lens or an optical function corresponding to the optical function, but is not limited thereto. The first region 131 may be configured to exhibit an optical function similar to that of a cone shape other than a cone or an optical function corresponding to the optical function. For example, the first region 131 may be configured to exhibit an optical function similar to that of a cone-shaped lens with a polygonal bottom as shown in FIG. 18 or an optical function corresponding to the optical function. In this case, the first inclined surface 26A is formed as shown by the solid line in FIG. 19. In this specification, the term "cone" is a concept that includes not only a straight cone but also an oblique cone.

[0150] The first region 131 may be configured to exhibit an optical function similar to that of a frustum-shaped lens or an optical function corresponding to the optical function. In this case, the first region 131 may exhibit an optical function similar to that of a frustum-shaped lens with the apex of a right pyramid removed as shown in Figures 20A and 20B, or an optical function corresponding to the optical function. The first region 131 may be configured to exhibit an optical function similar to that of a frustum-shaped lens with the apex of an oblique pyramid removed, or an optical function corresponding to the optical function. Figure 20B shows a cross section of the unit optical element 13 when the concavo-convex structure 25 is configured so that the first region 131 exhibits an optical function similar to that of a frustum-shaped lens or an optical function corresponding to the optical function.

[0151] The first region 131 may be configured to exhibit an optical function similar to that of a lens having a substantially pyramidal or substantially frustum shape, or an optical function corresponding to the optical function. The first region 131 may be configured to exhibit an optical function similar to that of a lens having a shape in which a part of a pyramid, a frustum, a substantially pyramidal or a substantially frustum is cut out along any plane perpendicular to the base, as shown in Fig. 21. In this case, the first inclined surface 26A is formed as shown by the dashed line in Fig. 19.

[0152] Even when the first region 131 exerts an optical function similar to or corresponding to the lens of any of the above-mentioned shapes, the concave-convex structure 25 of the first region 131 is formed so that the multiple first inclined surfaces 26A are aligned in a direction toward the first reference line L1. In addition, the multiple first inclined surfaces 26A form the side surfaces or parts of the side surfaces at different height positions of a pyramid, a frustum, an approximately pyramid, and an approximately pyramid. Even when the multiple first inclined surfaces 26A exert an optical function similar to or corresponding to the lens of a pyramid, a frustum, an approximately pyramid, and an approximately pyramid, the multiple first inclined surfaces 26A may be similar to each other. Also, as shown in FIG. 20B, etc., the first inclined surfaces 26A are represented by straight lines in a cross section of the unit optical element 13 along the direction in which the multiple first inclined surfaces 26A are aligned.

[0153] In the case where the first region 131 exhibits an optical function similar to or corresponding to any of the above-mentioned shapes of lenses, the unit shaping element 23 has the following characteristics so that the first region 131 exhibits these optical functions. That is, as described above, the multiple first inclined surfaces 26A are aligned in the direction toward the first reference line L1. Also, the multiple first inclined surfaces 26A are inclined toward the first reference line L1.

[0154] As an additional feature, the unit shaping element 23 has the following feature. That is, in a cross section of the unit optical element 13 along the direction in which the multiple first inclined surfaces 26A are arranged, the standard deviation of the pitch WA1 of the multiple first inclined surfaces 26A on one side of the first reference line L1 is 5 μm or less. The pitches WA1 may be equal to each other. Also, on one side of the first reference line L1, the standard deviation of the heights H26 of the multiple first inclined surfaces 26A is 1 μm or less. The heights H26 may be equal to each other. Furthermore, in the above cross section, when multiple first inclined surfaces 26A exist on the other side of the first reference line L1, the standard deviation of the pitches WA2 of the first inclined surfaces 26A on the other side of the first reference line L1 is 5 μm or less. The pitches WA2 may be equal to each other. On the other side of the first reference line L1, the standard deviation of the heights H26 of the first inclined surfaces 26A is 1 μm or less. The heights H26 may be equal to each other. Here, the average value of the pitch WA1 and the average value of the pitch WA2 may be equal to each other or may be different from each other.

[0155] Alternatively, instead of or in addition to the above additional features, the unit shaping element 23 may have the following additional features. That is, in the above cross section, the difference between the maximum value and the minimum value of the first inclined surface angle θA of the first inclined surface 26A on one side of the first reference line L1 is 1° or less. Furthermore, in the above cross section, when a plurality of first inclined surfaces 26A are present on the other side of the first reference line L1, the difference between the maximum value and the minimum value of the first inclined surface angle θA of the first inclined surface 26A on the other side of the first reference line L1 is 1° or less. The average value of the first inclined surface angle θA on one side of the first reference line L1 and the average value of the first inclined surface angle θA on the other side of the first reference line L1 may be equal to each other or may be different from each other.

[0156] <Second area> The unit optical element 13 may have a second region 132 in addition to the first region 131. FIG. 20B shows a cross section of the unit optical element 13 in the case where the first region 131 exerts an optical function similar to that of a frustum-shaped or approximately frustum-shaped lens or an optical function corresponding to the optical function. As shown in FIG. 20B, the unit optical element 13 includes a second region 132 adjacent to the first region 131 in the direction in which the first inclined surfaces 26A are arranged. In the example shown in FIG. 20B, the shaping surface 20a in the second region 132 is a flat surface. In other words, the shaping surface 20a includes a flat surface between the first reference line L1 and the inclined surface 26A closest to the first reference line L1. The shaping surface 20a in the second region 132 may be a curved surface. In other words, the shaping surface 20a may include a curved surface between the first reference line L1 and the inclined surface 26A closest to the first reference line L1. The shaping surface 20a in the second region 132 may have a shape of a part of a sphere. The shaping surface 20a in the second region 132 may exhibit an optical function similar to or corresponding to a lens having a curved lens surface such as a spherical lens or a cylindrical lens (hereinafter, also referred to as a "curved lens").

[0157] Also, as shown in FIG. 22 to FIG. 25G, the shaping surface 20a in the second region 132 may include a plurality of second inclined surfaces 26C inclined with respect to the normal direction Dn of the decorative laminate 10, and a plurality of second connection surfaces 26D connecting the adjacent second inclined surfaces 26C. The plurality of second inclined surfaces 26C are aligned in a direction toward an arbitrary second reference line L2 extending along the normal direction Dn. In these examples, the plurality of second inclined surfaces 26C are aligned in a direction toward the second reference line L2 and in a direction toward the first reference line L1. Also, the plurality of first inclined surfaces 26A are aligned in a direction toward the first reference line L1 and in a direction toward the second reference line L2. In the examples shown in FIG. 22 to FIG. 25G, the second reference line L2 coincides with the first reference line L1, but is not limited thereto. The second reference line L2 does not have to coincide with the first reference line L1. Also, in these examples, the second region 132 includes at least 10 second inclined surfaces 26C. The number of second inclined surfaces 26C included in the second region 132 may be 10 or more, 50 or more, 100 or more, or 200 or more.

[0158] In the example shown in Figures 22 to 25D, the second tilting surface 26C is located close to the reference line. Therefore, in the example shown in Figures 22 to 25D, the second tilting surface 26C is also referred to as a "reference line close tilting surface." Also, in the example shown in Figures 22 to 25D, the first tilting surface 26A is farther from the reference line than the second tilting surface 26C. Therefore, in the example shown in Figures 22 to 25D, the first tilting surface 26A is also referred to as a "reference line far tilting surface."

[0159] On the other hand, in the example shown in Figures 25E to 25G, the first tilting surface 26A is located close to the reference line, and the second tilting surface 26C is located farther from the reference line than the first tilting surface 26A. Therefore, in the example shown in Figures 25E to 25G, the first tilting surface 26A is also referred to as the "reference line close tilting surface" and the second tilting surface 26C is also referred to as the "reference line distant tilting surface."

[0160] 22 to 25G, the second inclined surfaces 26C correspond to the lens surfaces obtained by dividing a continuous convex lens surface along a surface perpendicular to the thickness direction of the lens surface, and the second connecting surface 26D corresponds to the rise surface connecting adjacent lens surfaces.

[0161] The second region 132 is a region extending from the outermost inclined surface 26Co of the multiple second inclined surfaces 26C to the innermost inclined surface 26Cc of the multiple second inclined surfaces 26C when viewed in the normal direction Dn of the decorative laminate 10.

[0162] In this specification, the angle θC of the second inclined surface 26C with respect to the normal direction Dn of the decorative laminate 10 (hereinafter also referred to as the "second inclined surface angle") is measured as an angle of a straight line LC connecting the top and bottom of each second inclined surface 26C with respect to the normal direction Dn in the cross section of the molding layer 20 along the direction in which the multiple second inclined surfaces 26C are arranged, as shown in Figure 23B, etc. Similarly, in this specification, the angle θD of the second connecting surface 26D with respect to the normal direction Dn of the decorative laminate 10 (hereinafter also referred to as the "second connecting surface angle") is measured as an angle of a straight line LD connecting the top and bottom of each second connecting surface 26D with respect to the normal direction Dn in the cross section of the molding layer 20 along the direction in which the multiple second connecting surfaces 26D are arranged, as shown in Figure 23B. The second inclination surface angle θC of each second inclination surface 26C is greater than the second connection surface angle θD of the second connection surface 26D connected to that second inclination surface 26C.

[0163] In the example shown in FIG. 22, the mold layer 20 has a concave-convex structure 25 formed in the second region 132 to allow the second region 132 to function as a cone-shaped, frustum-shaped, approximately cone-shaped, or approximately cone-shaped lens. In this example, the shape of the cone, frustum, approximately cone-shaped, or approximately cone-shaped (hereinafter also referred to as the "second cone or frustum") corresponding to the concave-convex structure 25 in the second region 132 is different from the shape of the cone, frustum, approximately cone-shaped, or approximately cone-shaped (hereinafter also referred to as the "first cone or frustum") corresponding to the concave-convex structure 25 in the first region 131. More specifically, the shape of the base of the first cone or frustum is different from the shape of the base of the second cone or frustum. In this example, the first region 131 is configured to exhibit an optical function similar to or corresponding to a lens having a frustum shape (first frustum) with a square bottom, and the second region 132 is configured to exhibit an optical function similar to or corresponding to a lens having a cone shape (second frustum) with a circular bottom. Of course, the first region 131 may be configured to exhibit an optical function similar to or corresponding to a lens having a cone shape, frustum shape, approximately cone shape, or approximately frustum shape other than the frustum shape shown in FIG. 22. In addition, the second region 132 may be configured to exhibit an optical function similar to or corresponding to a lens having a cone shape, frustum shape, approximately cone shape, or approximately frustum shape other than the cone shape shown in FIG. 22.

[0164] 22, the second tilting surfaces 26C may have the shape of side surfaces at different height positions of the second pyramid or frustum. In this case, the second tilting surfaces 26C may have similar shapes. The second tilting surfaces 26C may be represented by straight lines in a cross section of the unit optical element 13 along the direction in which the first tilting surfaces 26A and the second tilting surfaces 26C are arranged.

[0165] 22, the second region 132 is configured to provide an optical function similar to that of a convex lens or an optical effect corresponding to the optical function to the light incident from the front side surface 11 of the decorative laminate 10. However, the present invention is not limited to this, and the second region 132 may be configured to provide an optical function similar to that of a concave lens or an optical effect corresponding to the optical function to the light incident from the front side surface 11 of the decorative laminate 10. This makes it possible to express a rich three-dimensional effect that is greater than the thickness of the decorative laminate 10, and to express a complex design.

[0166] FIG. 23A shows a cross section of the unit optical element 13 along the line 23A-23A in FIG. 22. FIG. 23B shows an enlarged view of the portion surrounded by the two-dot chain line in FIG. 23A. In the example shown in FIG. 22, the second tilt surfaces 26C extend so as to surround the second reference line L2. Therefore, as shown in FIG. 23A, in the cross section of the unit optical element 13 along the direction in which the second tilt surfaces 26C are arranged, the second tilt surfaces 26C are present on both sides of the second reference line L2. In the illustrated example, the second reference line L2 coincides with the perpendicular line of the second pyramid (the line perpendicularly extending from the apex of the second pyramid to the base).

[0167] The unit shaping element 23 has the following characteristics so that the second region 132 exhibits an optical function similar to that of a cone-shaped, frustum-shaped, approximately cone-shaped, or approximately frustum-shaped lens, or an optical function corresponding to the optical function. That is, as described above, the multiple second inclined surfaces 26C are aligned in a direction toward the second reference line L2. The multiple second inclined surfaces 26C are inclined toward the second reference line L2. In the example shown in FIG. 23A, in the above cross section, the second inclined surface 26C is inclined in a first direction D1 with respect to the normal direction Dn on one side of the second reference line L2 (for example, the left side of FIG. 23A), and is inclined in a second direction D2 opposite to the first direction D1 with respect to the normal direction Dn on the other side of the second reference line L2 (for example, the right side of FIG. 23A). In the illustrated example, the first inclined surface 26A is inclined toward the first reference line L1 and the second reference line L2. The second inclined surface 26C is inclined toward the first reference line L1 and the second reference line L2.

[0168] As an additional feature, the unit shaping element 23 has the following feature. As shown in FIG. 23A, in the cross section of the unit optical element 13 along the direction in which the multiple second inclined surfaces 26C are arranged, the standard deviation of the pitch WC1 of the multiple second inclined surfaces 26C on one side of the second reference line L2 (for example, the left side of FIG. 23A) is 5 μm or less. The pitches WC1 may be equal to each other. Also, on one side of the second reference line L2, the standard deviation of the heights (dimension in the Z direction Dz) H26 of the multiple second inclined surfaces 26C is 1 μm or less. The heights H26 may be equal to each other. Furthermore, as shown in FIG. 23A, when multiple second inclined surfaces 26C are present on the other side of the second reference line L2 (for example, the right side of FIG. 23A) in the cross section, the standard deviation of the pitch WC2 of the second inclined surfaces 26C on the other side of the second reference line L2 is 5 μm or less. The pitches WC2 may be equal to each other. Also, on the other side of the second reference line L2, the standard deviation of the heights H26 of the multiple second inclined surfaces 26C is 1 μm or less. The heights H26 may be equal to each other. Here, the average value of the pitches WC1 and the average value of the pitches WC2 may be equal to each other or may be different from each other.

[0169] Alternatively, instead of or in addition to the above additional features, the unit shaping element 23 may have the following additional features. That is, in the cross section of the unit optical element 13 along the direction in which the multiple second inclined surfaces 26C are arranged, the difference between the maximum value and the minimum value of the second inclined surface angle θC of the second inclined surface 26C on one side of the second reference line L2 is 1° or less. Furthermore, as shown in FIG. 23A, in the above cross section, when multiple second inclined surfaces 26C exist on the other side of the second reference line L2, the difference between the maximum value and the minimum value of the second inclined surface angle θC of the second inclined surface 26C on the other side of the second reference line L2 is 1° or less. The average value of the second inclined surface angle θC on one side of the second reference line L2 and the average value of the second inclined surface angle θC on the other side of the second reference line L2 may be equal to each other or may be different from each other.

[0170] On one side of the reference lines L1 and L2, the average value of the pitch WC1 of the second inclined surface 26C may be different from the average value of the pitch WA1 of the first inclined surface 26A. In the example shown in FIG. 23A and FIG. 23B, the average value of the pitch WC1 is larger than the average value of the pitch WA1, but is not limited to this. The average value of the pitch WC1 may be smaller than the average value of the pitch WA1. In addition, on the other side of the reference lines L1 and L2, the average value of the pitch WC2 of the second inclined surface 26C may be different from the average value of the pitch WA2 of the first inclined surface 26A. In the example shown in FIG. 23A and FIG. 23B, the average value of the pitch WC2 is larger than the average value of the pitch WA2, but is not limited to this. The average value of the pitch WC2 may be smaller than the average value of the pitch WA2.

[0171] Furthermore, on one side of the reference lines L1, L2, the average value of the second inclined surface angle θC of the second inclined surface 26C and the average value of the first inclined surface angle θA of the first inclined surface 26A may be different. In the example shown in FIG. 23A and FIG. 23B, on one side of the reference lines L1, L2, the average value of the second inclined surface angle θC is larger than the average value of the first inclined surface angle θA, but this is not limited to this. On one side of the reference lines L1, L2, the average value of the second inclined surface angle θC may be smaller than the average value of the first inclined surface angle θA. Also, on the other side of the reference lines L1, L2, the average value of the second inclined surface angle θC of the second inclined surface 26C and the average value of the first inclined surface angle θA of the first inclined surface 26A may be different. 23A and 23B, the average value of the second inclined surface angle θC is greater than the average value of the first inclined surface angle θA on the other side of the reference lines L1 and L2, but is not limited to this. The average value of the second inclined surface angle θC may be smaller than the average value of the first inclined surface angle θA on the other side of the reference lines L1 and L2.

[0172] In the example shown in FIG. 24, a Fresnel lens structure is formed on the shaping surface 20a of the second region 132. In this case, the second inclined surfaces 26C correspond to a plurality of lens surfaces (hereinafter also referred to as "divided lens surfaces") obtained by dividing the lens surface of a curved lens such as a spherical lens or a cylindrical lens into a plurality of parts along a surface perpendicular to the thickness direction (optical axis direction) of the curved lens. The second connecting surfaces 26D correspond to rise surfaces connecting adjacent divided lens surfaces. In the example shown in FIG. 24, the second region 132 is configured to provide the same optical function as a convex lens or an optical effect corresponding to the optical function to the light incident from the front side surface 11 of the decorative laminate 10. However, without being limited thereto, the second region 132 may be configured to provide the same optical function as a concave lens or an optical effect corresponding to the optical function to the light incident from the front side surface 11 of the decorative laminate 10. This allows for a rich three-dimensional effect that is greater than the thickness of the decorative laminate 10 to be expressed, and allows for a complex design to be expressed.

[0173] FIG. 25A shows a cross section of the unit optical element 13 shown in FIG. 24 along the line 25A-25A. FIG. 25B shows an enlarged view of the portion surrounded by the two-dot chain line in FIG. 25A. In the example shown in FIG. 24, the second tilt surfaces 26C extend so as to surround the second reference line L2. Therefore, as shown in FIG. 25A, in the cross section of the unit optical element 13 along the direction in which the second tilt surfaces 26C are arranged, the second tilt surfaces 26C are present on both sides of the second reference line L2. In the illustrated example, the second reference line L2 coincides with the optical axis of the curved lens.

[0174] When the second region 132 exerts an optical function similar to that of a curved lens such as a spherical lens or a cylindrical lens, or an optical function corresponding to the optical function, the unit shaping element 23 has the following characteristics. That is, as described above, the multiple second inclined surfaces 26C are aligned in a direction toward the second reference line L2. The multiple second inclined surfaces 26C incline toward the second reference line L2. In the example shown in FIG. 25A, in the above cross section, the second inclined surface 26C inclines in a first direction D1 with respect to the normal direction Dn on one side of the second reference line L2 (for example, the left side of FIG. 25A), and inclines in a second direction D2 opposite to the first direction D1 with respect to the normal direction Dn on the other side of the second reference line L2 (for example, the right side of FIG. 25A). Also, in this example, the first inclined surface 26A inclines toward the first reference line L1 and the second reference line L2. The second inclined surface 26C is inclined toward the first reference line L1 and the second reference line L2.

[0175] As an additional feature, the unit shaping element 23 has the following feature. That is, as shown in Fig. 25A and Fig. 25B, in the above cross section, the standard deviation of the pitch WC1 of the second inclined surface 26C on one side of the second reference line L2 (for example, the left side of Fig. 25A) is greater than 5 μm. Also, the standard deviation of the height (dimension in the Z direction Dz) H26 of the multiple second inclined surfaces 26C on one side of the second reference line L2 is 1 μm or less. The heights H26 may be equal to each other. Furthermore, as shown in Fig. 25A, in the above cross section, when multiple second inclined surfaces 26C are present on the other side of the second reference line L2 (for example, the right side of Fig. 25A), the standard deviation of the pitch WC2 of the second inclined surface 26C on the other side of the second reference line L2 is greater than 5 μm. Furthermore, the standard deviation of the heights (dimension in the Z direction Dz) H26 of the multiple second inclined surfaces 26C on the other side of the second reference line L2 is 1 μm or less. The heights H26 may be equal to each other. The pitches WC1 and WC2 each become smaller as they move away from the second reference line L2. The average value of the pitch WC1 and the average value of the pitch WC2 may be equal to each other or may be different from each other.

[0176] Alternatively, instead of the above additional feature, the unit shaping element 23 has the following additional feature. As shown in FIG. 25C and FIG. 25D, in the above cross section, the standard deviation of the pitch WC1 of the second inclined surface 26C on one side of the second reference line L2 (for example, the left side of FIG. 25C) is 5 μm or less. The pitches WC1 may be equal to each other. Also, the standard deviation of the height (dimension in the Z direction Dz) H26 of the second inclined surface 26C on one side of the second reference line L2 is greater than 1 μm. Furthermore, as shown in FIG. 25C, when a plurality of second inclined surfaces 26C are present on the other side of the second reference line L2 (for example, the right side of FIG. 25C) in the above cross section, the standard deviation of the pitch WC2 of the second inclined surface 26C on the other side of the second reference line L2 is 5 μm or less. The pitches WC2 may be equal to each other. In addition, the standard deviation of the height H26 of the second inclined surface 26C on the other side of the second reference line L2 is greater than 1 μm. The height H26 increases with increasing distance from the second reference line L2 on both sides of the second reference line L2. Here, the average value of the pitch WC1 and the average value of the pitch WC2 may be equal to each other or may be different from each other.

[0177] Alternatively, instead of or in addition to the above additional features, the unit shaping element 23 has the following additional features. That is, in the above cross section, the difference between the maximum value and the minimum value of the second inclined surface angle θC of the second inclined surface 26C on one side of the second reference line L2 is greater than 1°. Furthermore, as shown in FIG. 25A and FIG. 25C, in the above cross section, when a plurality of second inclined surfaces 26C exist on the other side of the second reference line L2, the difference between the maximum value and the minimum value of the second inclined surface angle θC of the second inclined surface 26C on the other side of the second reference line L2 is greater than 1°. The second inclined surface angle θC becomes smaller as it moves away from the second reference line L2 on each of the one side and the other side of the second reference line L2. The average value of the second inclined surface angle θC on one side of the second reference line L2 and the average value of the second inclined surface angle θC on the other side of the second reference line L2 may be equal to each other or may be different from each other.

[0178] In the example shown in FIG. 22 to FIG. 25D, the second region 132 is located inside the first region 131. In other words, the second region 132 is closer to the reference lines L1, L2 than the first region 131. Of the multiple inclined surfaces 26A, 26C that the shaping surface 20a has, the second inclined surface 26C is closest to the reference lines L1, L2. In other words, the second region 132 includes 10 inclined surfaces 26C that are closest to the reference lines L1, L2 among the multiple inclined surfaces 26A, 26C. In addition, the first region 131 is located farther from the reference lines L1, L2 than the second region 132. The first region 131 includes 10 inclined surfaces 26A that are continuously arranged in a direction toward the reference lines L1, L2 at a position farther from the reference lines L1, L2 than the second inclined surface 26C.

[0179] Unlike the above-mentioned example, the second region 132 may be located outside the first region 131. In other words, the second region 132 may be farther from the reference lines L1, L2 than the first region 131. In the example shown in FIG. 25E to FIG. 25G, among the multiple inclined surfaces 26A, 26C that the shaping surface 20a has, the first inclined surface 26A is closest to the reference lines L1, L2. In other words, the first region 131 includes the 10 inclined surfaces 26A that are closest to the reference lines L1, L2 among the multiple inclined surfaces 26A, 26C. In addition, the second region 132 is located farther from the reference lines L1, L2 than the first region 131. The second region 132 includes 10 inclined surfaces 26C that are continuously arranged in a direction toward the reference lines L1, L2 at a position farther from the reference lines L1, L2 than the first inclined surface 26A. In the example shown in Fig. 25E, the second region 132 exhibits an optical function similar to or corresponding to a lens having a cone shape, a frustum shape, a substantially cone shape, or a substantially frustum shape. In the examples shown in Fig. 25F and Fig. 25G, a Fresnel lens structure is formed on the shaping surface 20a in the second region 132, and the second region 132 exhibits an optical function similar to or corresponding to a part of a curved lens such as a spherical lens or a cylindrical lens.

[0180] Furthermore, when the decorative laminate 10 has multiple unit optical elements 13, a concave-convex structure 25 including the above-mentioned first inclined surface 26A and first connecting surface 26B may be formed on some of the unit shaping elements 23, and the above-mentioned Fresnel lens structure may be formed on some other unit shaping elements 23.

[0181] In addition, in consideration of forming the concave-convex structure 25 with high accuracy and the adhesion between the shaping surface 20a and the brightness adjusting layer 30, the second connecting surface angle θ is preferably 15° or more, and more preferably 25° or more. In addition, in consideration of ensuring a sufficient area of ​​the second inclined surface 26C, the second connecting surface angle θ is preferably 55° or less, and more preferably 45° or less. Therefore, the second connecting surface angle θ may be 15° or more and 55° or less.

[0182] <<Modification 1 of the Brightness Adjustment Layer>> In the above-mentioned example, the brightness adjustment layer 30 is the colored layer 30a, but the present invention is not limited to this. As shown in Fig. 26A, the brightness adjustment layer 30 may be a reflective layer 30b.

[0183] The reflective layer 30b covers the shaping surface 20a of the shaping layer 20 to form a reflective interface between the shaping surface 20a and the reflective layer 30b. The reflective layer 30b improves the reflectance of visible light at the reflective interface 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 is a metal reflective layer formed by deposition or coating of a metal material. 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 surfaces 26B and 26D. The thickness of the reflective layer 30b may be half or less of the height H26 of the connection surfaces 26B and 26D, 25% or less of the height H26 of the connection surfaces 26B and 26D, or 10% or less of the height H26 of the connection surfaces 26B and 26D. The reflective layer 30b having such a thickness does not fill in 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.

[0184] In the example shown in Fig. 26A, the unevenness of the reflective layer 30b is filled with the bonding layer 35. However, similar to the example shown in Fig. 4, the reflective layer 30b may be formed so as to fill the unevenness of the shaping surface 20a.

[0185] The material of the reflective layer 30b is preferably a material that improves the reflectance of the reflective interface formed by the reflective layer 30b, and more preferably a material that has radio wave transparency. In this case, the material constituting the reflective layer 30b may be, for example, a metal material such as aluminum, indium, or tin.

[0186] 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. 26B, 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 shaping elements 23.

[0187] The thickness of the reflective layer 30b is preferably a thickness that can improve the reflectance of the reflective interface 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 the cross section of the decorative laminate 10 using a scanning electron microscope.

[0188] In addition, when the brightness adjustment layer 30 is a reflective layer 30b, the inventors adjusted the reflectance of the front side surface 11 of the decorative laminate 10 as follows, that is, the total light reflectance (R SCI ) and diffuse reflectance (R SCE ) is the following formula: 3%≦R SCI ≦35%, 0.15%≦R SCE ≦25%, 1.3≦R SCI / R SCE ≦15, It has been discovered that by adjusting the reflectance at the front surface 11 of the decorative laminate 10 so as to satisfy the above, it is possible to make the thickness of the decorative laminate 10 appear thicker than its actual thickness and to enhance the three-dimensional effect of the decorative laminate 10.

[0189] <Method of manufacturing a decorative member having a decorative laminate shown in FIG. 26A> 10 to 12, 27A and 27B, a method for manufacturing a decorative member 3 having the decorative laminate shown in Fig. 26A (i.e., the decorative member 3 shown in Fig. 2A) will be described. Figs. 27A and 27B are cross-sectional views showing a method for manufacturing the decorative laminate 10.

[0190] First, the release layer 37a is formed on the substrate 72 by the same method as that shown in FIGS. 10 to 12, and the shape-imparting layer 20 having the concave-convex structure 25 is formed on the release layer 37a.

[0191] Next, as shown in Fig. 27A, a reflective layer 30b is formed on the shaping surface 20a by a film forming technique such as sputtering or vacuum deposition. In the illustrated example, the connection surface angles θB, θD of the connection surfaces 26B, 26D of the concave-convex structure 25 are not 0° but 15° or more. This makes it easy to form the reflective layer 30b on the connection surfaces 26B, 26D.

[0192] Next, as shown in FIG. 27B, the bonding layer 35 is formed on the reflective layer 30b. The surface of the reflective layer 30b that contacts the bonding layer 35 has unevenness according to the uneven structure 25 of the mold-imparting layer 20. In the illustrated example, the connection surface angles θB, θD of the connection surfaces 26B, 26D of the mold-imparting layer 20 are 15° or more, so that the adhesion between the portion covering the connection surfaces 26B, 26D of the reflective layer 30b and the bonding layer 35 is improved compared to when the connection surface angles θB, θD are 0°. As a result, the adhesion between the reflective layer 30b and the bonding layer 35 is improved. In this manner, a transfer sheet 70 including the decorative laminate 10 is produced.

[0193] Next, the transfer sheet 70 is placed in a mold for forming the molded portion 65. Next, molten resin is introduced between the back surface 12 (i.e., the bonding layer 35) 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.

[0194] <<Modification 2 of the Brightness Adjustment Layer>> In the modified example shown in FIG. 26A to FIG. 27B, the brightness adjustment layer 30 is the reflective layer 30b, but the present invention is not limited to this. The brightness adjustment layer 30 may be a refractive index modulation layer 30c. The refractive index modulation layer 30c is a layer whose refractive index is different from that of the shape-imparting layer 20. When the concave-convex structure 25 of the shape-imparting layer 20 is covered with the refractive index modulation layer 30c, a reflective interface is formed between the shape-imparting layer 20 and the refractive index modulation layer 30c, and the reflectance of light on the shape-imparting surface 20a can be improved. This allows the brightness of the light reflected by the decorative laminate 10 to be adjusted.

[0195] 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.

[0196] 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.

[0197] In the illustrated example, the connection surface angles θB, θD of the connection surfaces 26B, 26D of the concave-convex structure 25 are not 0° but are 15° or more. This makes it easy to form the refractive index modulation layer 30c on the connection surfaces 26B, 26D.

[0198] The refractive index modulation layer 30c may be formed as a thin film-like layer, similar to the reflective layer 30b shown in FIG. 26A. In this case, the thickness of the refractive index modulation layer 30c may be thinner than the height H26 of the connecting surfaces 26B, 26D. The thickness of the refractive index modulation layer 30c may be half or less of the height H26 of the connecting surfaces 26B, 26D, 25% or less of the height H26 of the connecting surfaces 26B, 26D, or 10% or less of the height H26 of the connecting surfaces 26B, 26D. 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.

[0199] 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.

[0200] The thickness of the refractive index modulation layer 30c is preferably a thickness that can improve the reflectance of the reflection interface 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.

[0201] When the luminance adjustment layer 30 is a refractive index modulation layer 30c, the inventors adjusted the reflectance of the front surface 11 of the decorative laminate 10 as follows, that is, the total light reflectance (R SCI ) and diffuse reflectance (R SCE ) is the following formula: 3%≦R SCI ≦35%, 0.15%≦R SCE ≦25%, 1.3≦R SCI / R SCE ≦15, It has been discovered that by adjusting the reflectance at the front surface 11 of the decorative laminate 10 so as to satisfy the above, it is possible to make the thickness of the decorative laminate 10 appear thicker than its actual thickness and to enhance the three-dimensional effect of the decorative laminate 10.

[0202] <<Modification 3 of the Brightness Adjustment Layer>> In the above-mentioned example, the luminance adjustment layer 30 forms a reflective interface 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 with a layer (the bonding layer 35 in the example shown in FIG. 26A) facing the surface 33 opposite to the surface 32 facing the shape-imparting layer 20. In this case, as shown in FIG. 26A, 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 on the opposite surface 33 will have a shape corresponding to the unevenness of the shape-imparting surface 20a. Therefore, the reflective interface 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. Also in this case, the luminance adjusting layer 30 adjusts the reflectance of visible light at the reflective interface, and the reflectance of visible light measured on the front surface 11 side of the decorative laminate 10 is adjusted.

[0203] 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 reflective interface with the layer facing the opposite surface 33 (the bonding layer 35 in FIG. 26A). 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 35 in FIG. 26A). In this case, a reflective interface 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.

[0204] Of course, when the brightness adjusting layer 30 has unevenness on the opposite surface 33 thereof that corresponds to the unevenness of the shaping surface 20a, a reflective interface may be formed on both sides of the brightness adjusting layer 30.

[0205] <<Other variations>> <Colored layer> 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. 28, 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. More specifically, the bonding layer 35, 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 brightness adjustment layer 30. In the example shown in FIG. 28, the colored layer 45 is observed through the functional layer 37, the shape-imparting layer 20, and the brightness adjustment layer 30. Therefore, the functional layer 37, the shape-imparting layer 20, and the brightness adjustment layer 30 are transparent. As shown in Fig. 2C, the colored layer 45 may be disposed closer to the front surface 11 of the decorative laminate 10 than the shape-imparting layer 20 and the brightness adjustment layer 30. In this case, the shape-imparting layer 20 and / or the brightness adjustment layer 30 are observed through the colored layer 45. Therefore, the colored layer 45 is transparent.

[0206] 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. 28, the color layer 45 may function as a planarizing layer that fills in the unevenness of the luminance adjustment layer 30.

[0207] In the decorative laminate 10 shown in FIG. 28, even when the decorative laminate 10 includes the colored layer 45, the total light reflectance (R SCI ) and diffuse light reflectance (R SCE ) can effectively make the thickness of the decorative laminate 10 appear thicker than its actual thickness.

[0208] When the colored layer 45 is colored with a pigment or dye, the reflectance of the front surface 11 of the decorative laminate 10 is adjusted as follows: SCI ) and diffuse reflectance (R SCE ) is the following formula: 3%≦R SCI ≦35%, 0.15%≦R SCE ≦25%, 1.3≦R SCI / R SCE ≦15, By adjusting the reflectance of the front side surface 11 of the decorative laminate 10 so as to satisfy the above, the thickness of the decorative laminate 10 can be made to appear thicker than the actual thickness. In addition, when the decorative laminate 10 is observed, the color of the colored layer 45 is clearly perceived.

[0209] Specifically, when the colored layer 45 is colored with a black dye or pigment, the reflectance of the front surface 11 of the decorative laminate 10 is adjusted as follows, that is, the total light reflectance (R SCI ) and diffuse reflectance (R SCE ) is the following formula: 3%≦R SCI ≦12%, 0.4%≦R SCE ≦3%, 2≦R SCI / R SCE ≦12, By adjusting the reflectance of the front side surface 11 of the decorative laminate 10 so as to satisfy the above, the thickness of the decorative laminate 10 can be made to appear thicker than the actual thickness. In addition, the jet blackness of the decorative laminate 10 can be improved.

[0210] Furthermore, when the colored layer 45 is colored with a black dye or pigment, the reflectance of the front surface 11 of the decorative laminate 10 is adjusted as follows: SCI ) and diffuse reflectance (R SCE ) is the following formula: 4%≦R SCI ≦8%, 0.8%≦R SCE ≦2%, 4≦R SCI / R SCE ≦8, By adjusting the reflectance of the front side surface 11 of the decorative laminate 10 so as to satisfy the above, the thickness of the decorative laminate 10 can be made to look much thicker than the actual thickness. In addition, the jet blackness of the decorative laminate 10 can be effectively enhanced.

[0211] The total light reflectance (R SCI ) and diffuse reflectance (R SCE ) can be adjusted by adjusting the weight ratio (P / V) of the pigment (P) to the resin (V) contained in the colored layer 45. More specifically, when the colored layer 45 is formed from a colorless and transparent resin and a pigment, P / V is preferably 0.2 or more, more preferably 0.5 or more, and even more preferably 0.8 or more. Furthermore, from the viewpoint of the durability of the colored layer 45 and its adhesion to other layers, P / V is preferably 2 or less, more preferably 1.5 or less, and even more preferably 1.2 or less. Thus, P / V may be 0.2 or more and 2 or less.

[0212] <Filled layer> 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. 29, 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. 29, the bonding layer 35, 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.

[0213] 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.

[0214] <Backer layer> As shown in FIG. 2D and FIG. 30, 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. 30, 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. The backer layer 55 forms the back side surface 12 of the decorative laminate 10.

[0215] 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.

[0216] 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. 2B, 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 the concealing layer 60 described later.

[0217] 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 35 can be used.

[0218] <Method of manufacturing the decorative member shown in FIG. 2D> 10 to 13, 31A and 31B, a method for manufacturing the decorative member 3 shown in Fig. 2D will be described. Fig. 31A and Fig. 31B are cross-sectional views showing a method for manufacturing the decorative laminate 10 shown in Fig. 2D and Fig. 30.

[0219] 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. 10 to Fig. 13. Then, as shown in Fig. 31A, a bonding layer 56 is formed on the brightness adjustment layer 30. Next, as shown in Fig. 31B, 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. 30 is produced.

[0220] 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. 2D is completed. Such a molding method for the decorative member 3 is known as insert molding.

[0221] <Functional layer> 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. 32, 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.

[0222] 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.

[0223] In the example shown in FIG. 2E and FIG. 32, 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.

[0224] <Method of manufacturing the decorative member shown in FIG. 2E> Next, a method for producing the decorative member 3 shown in Fig. 2E will be described with reference to Fig. 33A to Fig. 33C. Fig. 33A to Fig. 33C are cross-sectional views showing a method for producing the decorative laminate 10 shown in Fig. 2E and Fig. 32.

[0225] First, a flat substrate is prepared as the support layer 37b. Next, as shown in FIG. 33A, 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. 11 and FIG. 12. 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.

[0226] Next, as shown in Fig. 33B, the brightness adjustment layer 30 is formed on the shaping surface 20a of the shaping layer 20. Next, as shown in Fig. 33C, 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. 32 is produced.

[0227] 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.

[0228] 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.

[0229] <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. 33A and 33B.

[0230] First, the shape-imparting layer 20 is formed on the support layer 37b by the same method as shown in Fig. 33A. 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. 33B. In this manner, the decorative laminate 10 shown in Fig. 2F is produced.

[0231] 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.

[0232] <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.

[0233] <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.

[0234] <<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.

[0235] <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 35. The functional layer 37, the molding layer 20, the brightness adjustment layer 30, and the bonding layer 35 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 35 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 35 bonds the back surface 67 of the molding portion 65 to other layers of the decorative laminate 10.

[0236] 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 part 65 and the bonding layer 35. Therefore, the molding part 65 and the bonding layer 35 are transparent. The brightness adjustment layer 30 may also be transparent.

[0237] <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.

[0238] 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.

[0239] <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.

[0240] 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.

[0241] <Decorative parts shown in Fig. 2J> In the example shown in Fig. 2J, the decorative laminate 10 includes a concealing layer 60, a brightness adjustment layer 30, a molding layer 20, a functional layer 37, and a bonding layer 35. The concealing layer 60, the brightness adjustment layer 30, the molding layer 20, the functional layer 37, and the bonding layer 35 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 35 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 bonding layer 35 is bonded to the back surface 67 of the molding portion 65.

[0242] 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. 33A and FIG. 33B. Next, as shown in FIG. 34A, a concealing layer 60 is formed on the brightness adjustment layer 30. Next, as shown in FIG. 34B, a bonding layer 35 is formed on the other surface of the functional layer 37. After the step shown in FIG. 34B, the bonding layer 35 is bonded to the back side surface 67 of the molding portion 65. This produces the decorative member 3 shown in FIG. 2J.

[0243] 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 35, 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.

[0244] <<Reflectance of decorative materials>> In the above-mentioned example, the total light reflectance (R SCI ) and diffuse reflectance (R SCEIt has been explained that the thickness of the decorative laminate 10 is made to appear thicker than its actual thickness by adjusting the reflectance at the front side 11 of the decorative laminate 10 so that the total light reflectance (R ) satisfies the above-mentioned predetermined formula, but the same explanation applies to the decorative member 3. That is, in any of the cases where the decorative laminate 10 forms the front side 3a of the decorative member 3, where the decorative laminate 10 is disposed between the front side 3a and the molded portion 65 of the decorative member 3, where the decorative laminate 10 forms the back side 3b of the decorative member 3, and where the decorative laminate 10 is disposed between the back side 3b and the molded portion 65 of the decorative member 3, the total light reflectance (R SCI ) and diffuse reflectance (R SCE By adjusting the reflectance of the front side surface 3a of the decorative member 3 so that ) satisfies the above-mentioned predetermined formula, the thickness of the decorative member 3a can be made to appear thicker than its actual thickness.

[0245] As shown in Figures 2G to 2J, when the molded portion 65 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, the molded portion 65 reduces the total light reflectance (R SCI ) and diffuse reflectance (R SCE ) can be adjusted. In this case, the decorative laminate 10 may include a colored layer 45 as shown in FIG. 2K and FIG. 2L. When the decorative member 3 includes a colored molded portion 65 and a colored layer 45, the total light reflectance (R SCI ) and diffuse reflectance (R SCE 2L, the shape-imparting layer 20 and / or the luminance adjusting layer 30 are observed through the colored layer 45. Therefore, the colored layer 45 is transparent.

[0246] 2M and 2N, the decorative laminate 3 may include a colored layer 68. In this case, the colored layer 68 reduces the total light reflectance (R SCI ) and diffuse reflectance (R SCE ) can be adjusted. In the example shown in FIG. 2M, the colored layer 68 forms the front side surface 3a of the decorative laminate 3. 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 68. 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.

[0247] <<Shape of decorative parts>> The shape of the decorative member 3 may be any shape. In other words, the shape of the molded portion 65 to which the decorative laminate 10 is applied may be any shape. For example, as shown in FIG. 35, the decorative member 3 may include a curved surface 68. More specifically, the molded portion 65 may include a curved surface 68 corresponding to the curved surface 3c of the decorative member 3, and the decorative laminate 10 may cover the curved surface 68 of the molded portion 65. By covering the curved surface 68 with the decorative laminate 10, the observer 6 observing 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 6 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, the observer 6 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 less, and more preferably 100 mm or less.

[0248] According to the embodiment and its modified example described above, the decorative laminate 10 includes a shaping layer 20 and a brightness adjustment layer 30. The shaping layer 20 has a shaping surface 20a on which a concave-convex structure 25 is formed. The brightness adjustment layer 30 covers the shaping surface 20a. The decorative laminate 10 has at least one unit optical element 13. The unit optical element 13 reflects, refracts, and / or diffracts light incident on the front side surface 11 of the decorative laminate 10 according to the concave-convex structure 25. In the unit optical element 13, the shaping surface 20a includes a plurality of inclined surfaces 26A, 26C and a plurality of connecting surfaces 26B, 26D. The plurality of inclined surfaces 26A, 26C are aligned in a direction toward arbitrary reference lines L1, L2 extending along the normal direction Dn of the decorative laminate 10, and are inclined toward the reference lines L1, L2. The connection surfaces 26B, 26D connect the adjacent tilted surfaces 26A, 26C. The angles θA, θC of the tilted surfaces 26A, 26C with respect to the normal direction Dn are larger than the angles θB, θD of the connection surfaces 26B, 26D connected to the tilted surfaces 26A, 26C with respect to the normal direction Dn. In the cross section of the unit optical element 13 along the direction in which the multiple tilted surfaces 26A, 26C are arranged, the standard deviation of the pitch WA1 of the reference line adjacent tilted surface 26A on one side of the reference lines L1, L2 is 5 μm or less and the standard deviation of the height H26 is 1 μm or less. The reference line adjacent tilted surface 26A is a plurality of tilted surfaces arranged continuously at a position close to the reference lines L1, L2. In the illustrated example, the reference line adjacent tilted surface 26A is the 10 tilted surfaces 26A that are closest to the reference lines L1, L2 among the multiple tilted surfaces 26A, 26C. In this case, the region 131 including the reference line-proximate inclined surface 26A of the unit optical element 13 can provide an optical effect similar to or corresponding to that of a cone- or frustum-shaped lens to the light incident on the unit optical element 13. As a result, a rich three-dimensional effect that is greater than the thickness of the decorative laminate 10 can be expressed, enabling rich design expression with a luxurious feel.

[0249] According to the embodiment and its modified example described above, the inclined surfaces 26A, 26C may be lens surfaces, and the connecting surfaces 26B, 26D may be rise surfaces.

[0250] According to the embodiment and its modified example described above, the reference-line-proximate inclined surface 26A has a shape of a side surface or a part of the side surface at different height positions of a common first pyramid or frustum. In this case, the region 131 including the reference-line-proximate inclined surface 26A of the unit optical element 13 can provide the same optical effect as a pyramid- or frustum-shaped lens or an optical effect corresponding to the optical effect to the light incident on the unit optical element 13.

[0251] According to the embodiment and its modified example described above, the reference line proximity inclined surface 26A extends so as to surround the reference lines L1 and L2. The above-mentioned cross section of the unit optical element 13 includes the reference line proximity inclined surface 26A on both sides of the reference lines L1 and L2. In the above-mentioned cross section of the unit optical element 13, the standard deviation of the pitch WA2 of the reference line proximity inclined surface 26A on the other side of the reference lines L1 and L2 is 5 μm or less and the standard deviation of the height H26 is 1 μm or less. In this case, the region 131 including the reference line proximity inclined surface 26A of the unit optical element 13 can provide the light incident on the unit optical element 13 with an optical effect similar to that of a cone or frustum-shaped lens or an optical effect corresponding to the optical effect. As a result, a rich three-dimensional effect greater than the thickness of the decorative laminate 10 can be effectively expressed.

[0252] In this case, the average value of the pitch WA1 on one side of the reference lines L1, L2 of the reference line-proximate inclined surface 26A differs from the average value of the pitch WA2 on the other side of the reference lines L1, L2 in the above-mentioned cross section of the unit optical element 13. In this case, the region 131 including the reference line-proximate inclined surface 26A of the unit optical element 13 can provide, to the light incident on the unit optical element 13, an optical effect similar to that of a lens having an oblique pyramid shape or a frustum shape obtained by removing the apex of an oblique pyramid, or an optical effect corresponding to the optical effect.

[0253] According to the above-described modified example, the multiple inclined surfaces 26A and 26C have the reference line-distant inclined surfaces 26C arranged continuously at a position farther from the reference lines L1 and L2 than the reference line-proximate inclined surfaces 26A. The reference line-proximate inclined surfaces 26A are shaped as side surfaces or parts of the side surfaces at different height positions of a common first pyramid or frustum. The reference line-distant inclined surfaces 26C are shaped as side surfaces or parts of the side surfaces at different height positions of a common second pyramid or frustum. The shape of the bottom surface of the first pyramid or frustum and the shape of the bottom surface of the second pyramid or frustum are different from each other. In the illustrated example, the reference line-distant inclined surfaces 26C are further 10 inclined surfaces arranged continuously at a position farther from the reference lines L1 and L2 than the above-described 10 inclined surfaces 26A. In this case, the region 132 including the reference line-separated inclined surface 26C of the unit optical element 13 can provide the same optical effect as a frustum-shaped lens or an optical effect corresponding to the optical effect to the light incident on the unit optical element 13. As a result, the region 132 can also express a rich three-dimensional effect that is greater than the thickness of the decorative laminate 10, making it possible to express a rich design with a luxurious feel. In addition, a complex design can be expressed by combining the regions 131 and 132.

[0254] According to the above-described modified example, in the above-mentioned cross section of the unit optical element 13, the standard deviation of the pitch WC1 of the reference line-separated inclined surface 26C on one side of the reference lines L1 and L2 is 5 μm or less, and the standard deviation of the height is 1 μm or less. The reference line-separated inclined surface 26C is a plurality of inclined surfaces arranged continuously at a position farther from the reference lines L1 and L2 than the reference line-proximate inclined surface 26A. In the illustrated example, the reference line-separated inclined surface 26C is a further ten inclined surfaces arranged continuously at a position farther from the reference lines L1 and L2 than the ten inclined surfaces 26A. In this case, the region 132 including the reference line-separated inclined surface 26C of the unit optical element 13 can provide the same optical effect as that of a frustum-shaped lens or an optical effect corresponding to the optical effect to the light incident on the unit optical element 13. As a result, the above-mentioned region 132 can also express a rich three-dimensional effect that is greater than the thickness of the decorative laminate 10, making it possible to express a rich design with a luxurious feel.

[0255] According to the above-described modified example, in the above-mentioned cross section of the unit optical element 13, the standard deviation of the pitch WC1 of the reference line-separated inclined surface 26C on one side of the reference line L2 is greater than 5 μm, and the standard deviation of the height H26 is 1 μm or less. The reference line-separated inclined surface 26C is a plurality of inclined surfaces arranged continuously at a position farther from the reference lines L1 and L2 than the reference line-proximate inclined surface 26A. In the illustrated example, the reference line-separated inclined surface 26C is a further ten inclined surfaces arranged continuously at a position farther from the reference lines L1 and L2 than the ten inclined surfaces 26A. In this case, the region 132 including the reference line-separated inclined surface 26C of the unit optical element 13 can provide the light incident on the unit optical element 13 with an optical effect similar to that of a lens having a Fresnel lens structure or an optical effect corresponding to the optical effect. As a result, the above-mentioned region 132 can also express a rich three-dimensional effect that is greater than the thickness of the decorative laminate 10. As a result, it is possible to more effectively express a rich three-dimensional effect that is greater than the thickness of the decorative laminate 10, and to express a complex design by combining the above-mentioned regions 131 and 132. The pitch WC1 of the reference line-separated inclined surface 26C may become smaller as it becomes farther from the reference lines L1 and L2.

[0256] According to the above-described modified example, in the cross section of the unit optical element 13, the standard deviation of the pitch WC1 of the reference line-separated inclined surface 26C on one side of the reference lines L1 and L2 is 5 μm or less, and the standard deviation of the height is greater than 1 μm. The reference line-separated inclined surface 26C is a plurality of inclined surfaces arranged continuously at a position farther from the reference lines L1 and L2 than the reference line-proximate inclined surface 26A. In the illustrated example, the reference line-separated inclined surface 26C is a further ten inclined surfaces arranged continuously at a position farther from the reference lines L1 and L2 than the ten inclined surfaces 26A. In this case, the region 132 including the reference line-separated inclined surface 26C of the unit optical element 13 can provide the light incident on the unit optical element 13 with an optical effect similar to that of a lens having a Fresnel lens structure or an optical effect corresponding to the optical effect. As a result, the region 132 can also express a rich three-dimensional effect that is greater than the thickness of the decorative laminate 10. As a result, it is possible to more effectively express a rich three-dimensional effect that is greater than the thickness of the decorative laminate 10. In addition, it is possible to express a complex design by combining the above-mentioned regions 131 and 132. The height H26 of the reference line-separated inclined surface 26C may increase with increasing distance from the reference lines L1 and L2.

[0257] According to the above-described modified example, the decorative laminate 10 includes a shaping layer 20 and a brightness adjustment layer 30. The shaping layer 20 has a shaping surface 20a on which a concave-convex structure 25 is formed. The brightness adjustment layer 30 covers the shaping surface 20a. The decorative laminate 10 has at least one unit optical element 13. The unit optical element 13 reflects, refracts, and / or diffracts light incident on the front side surface 11 of the decorative laminate 10 according to the concave-convex structure 25. In the unit optical element 13, the shaping surface 20a includes a plurality of inclined surfaces 26A, 26C and a plurality of connecting surfaces 26B, 26D. The plurality of inclined surfaces 26A, 26C are aligned in a direction toward arbitrary reference lines L1, L2 extending along the normal direction Dn of the decorative laminate 10, and are inclined toward the reference lines L1, L2. The connection surfaces 26B, 26D connect the adjacent inclined surfaces 26A, 26C. The angles θA, θC of the inclined surfaces 26A, 26C with respect to the normal direction Dn are larger than the angles θB, θD of the connection surfaces 26B, 26D connected to the inclined surfaces 26A, 26C with respect to the normal direction Dn. In the cross section of the unit optical element 13 along the direction in which the multiple inclined surfaces 26A, 26C are arranged, the standard deviation of the pitch WC1 of the reference line adjacent inclined surface 26C on one side of the reference lines L1, L2 is larger than 5 μm and the standard deviation of the height H26 is 1 μm or less. Or, the standard deviation of the pitch WC1 of the reference line adjacent inclined surface 26C on one side of the reference lines L1, L2 is 5 μm or less and the standard deviation of the height H26 is larger than 1 μm. In the above cross section of the unit optical element 13, the standard deviation of the pitch WA1 of the reference line-away tilting surface 26A on one side of the reference lines L1 and L2 is 5 μm or less, and the standard deviation of the height H26 is 1 μm or less. The reference line-close tilting surface 26C is a plurality of tilting surfaces arranged continuously at a position close to the reference lines L1 and L2. The reference line-away tilting surface 26A is a plurality of tilting surfaces arranged continuously at a position farther from the reference lines L1 and L2 than the reference line-close tilting surface 26C. In the illustrated example, the reference line-close tilting surface 26C is the 10 tilting surfaces 26C closest to the reference lines L1 and L2. The reference line-away tilting surface 26A is another 10 tilting surfaces 26A arranged continuously at a position farther from the reference lines L1 and L2 than the above 10 tilting surfaces 26C.In this case, the region 131 including the reference line-separated inclined surface 26A of the unit optical element 13 can provide the light incident on the unit optical element 13 with an optical effect similar to that of a cone-shaped or frustum-shaped lens or an optical effect corresponding to the optical effect. This allows a rich three-dimensional effect greater than the thickness of the decorative laminate 10 to be expressed, making it possible to express a rich design with a sense of luxury. In addition, a complex design can be expressed by combining the above regions 131 and 132. Furthermore, if the above region 132 provides the light incident on the unit optical element 13 with an optical effect similar to that of a lens with a Fresnel lens structure or an optical effect corresponding to the optical effect, the above region 132 can also provide a rich three-dimensional effect greater than the thickness of the decorative laminate 10. As a result, a rich three-dimensional effect greater than the thickness of the decorative laminate 10 can be more effectively expressed.

[0258] In this modification, the inclined surfaces 26A, 26C may be lens surfaces, and the connecting surfaces 26B, 26D may be rise surfaces.

[0259] In this modification, the reference line-separated inclined surfaces 26A are shaped as sides or parts of the sides at different height positions of a common cone or frustum. In this case, the region 131 including the reference line-separated inclined surfaces 26A of the unit optical element 13 can provide the same optical effect as a cone or frustum-shaped lens or an optical effect corresponding to the optical effect to the light incident on the unit optical element 13. As a result, a rich three-dimensional effect that is greater than the thickness of the decorative laminate 10 can be effectively expressed.

[0260] In this modified example, the reference line-separated inclined surface 26A extends so as to surround the reference lines L1 and L2. The above-mentioned cross section of the unit optical element 13 includes the reference line-separated inclined surface 26A on both sides of the reference lines L1 and L2. In the above-mentioned cross section of the unit optical element 13, the standard deviation of the pitch WA2 of the reference line-separated inclined surface 26A on the other side of the reference lines L1 and L2 is 5 μm or less, and the standard deviation of the height is 1 μm or less. In this case, the region 131 including the reference line-separated inclined surface 26A of the unit optical element 13 can provide the same optical effect as a cone or frustum-shaped lens or an optical effect corresponding to the optical effect to the light incident on the unit optical element 13. As a result, a rich three-dimensional effect that is greater than the thickness of the decorative laminate 10 can be effectively expressed.

[0261] In this modified example, the average value of the pitch WA1 on one side of the reference lines L1, L2 of the reference line-separated inclined surface 26A may be different from the average value of the pitch WA2 on the other side of the reference lines L1, L2 in the above-mentioned cross section of the unit optical element 13. In this case, the region 131 including the reference line-separated inclined surface 26A of the unit optical element 13 can provide, to the light incident on the unit optical element 13, an optical effect similar to that of a frustum-shaped lens with the apex of an oblique pyramid removed, or an optical effect corresponding to the optical effect.

[0262] In this modified example, the pitches WC1, WC2 of the reference-line-proximate inclined surfaces 26C may become smaller as they move away from the reference lines L1, L2. In this case, the region 132 including the reference-line-proximate inclined surfaces 26C of the unit optical element 13 can provide the light incident on the unit optical element 13 with an optical effect similar to that of a lens having a Fresnel lens structure or an optical effect corresponding to the optical effect.

[0263] In this modified example, the height H26 of the reference-line-proximate inclined surface 26C increases with increasing distance from the reference lines L1 and L2. In this case, the reference-line-proximate inclined surface 26C can provide the light incident on the unit optical element 13 with an optical effect similar to or corresponding to that of a lens having a Fresnel lens structure.

[0264] According to the embodiment and the modified example thereof described above, the decorative laminate 10 includes a shaping layer 20 and a brightness adjustment layer 30. The shaping layer 20 has a shaping surface 20a on which a concave-convex structure 25 is formed. The brightness adjustment layer 30 covers the shaping surface 20a. The decorative laminate 10 has at least one unit optical element 13. The unit optical element 13 reflects, refracts, and / or diffracts light incident on the front side surface 11 of the decorative laminate 10 according to the concave-convex structure 25. In the unit optical element 13, the shaping surface 20a includes a plurality of inclined surfaces 26A, 26C and a plurality of connecting surfaces 26B, 26D. The plurality of inclined surfaces 26A, 26C are aligned in a direction toward arbitrary reference lines L1, L2 extending along the normal direction Dn of the decorative laminate 10, and are inclined toward the reference lines L1, L2. The connection surfaces 26B and 26D connect the adjacent tilted surfaces 26A and 26C.

In the cross section of the unit optical element 13 along the direction in which the multiple tilted surfaces 26A and 26C are arranged, the difference between the maximum and minimum values ​​of the angles of the reference line adjacent tilted surface 26A with respect to the normal direction Dn on one side of the reference lines L1 and L2 is 1° or less. The reference line adjacent tilted surface 26A is a plurality of tilted surfaces that are continuously arranged at positions close to the reference lines L1 and L2. In the illustrated example, the reference line adjacent tilted surface 26A is the 10 tilted surfaces among the multiple tilted surfaces 26A and 26C that are closest to the reference lines L1 and L2. In this case, the region 131 including the reference line-proximate inclined surface 26A of the unit optical element 13 can provide an optical effect similar to or corresponding to that of a cone- or frustum-shaped lens to the light incident on the unit optical element 13. As a result, a rich three-dimensional effect that is greater than the thickness of the decorative laminate 10 can be expressed, enabling rich design expression with a luxurious feel.

[0265] In this embodiment and its variations, the inclined surfaces 26A, 26C may be lens surfaces, and the connecting surfaces 26B, 26D may be rise surfaces.

The reference line-separated inclined surface 26C is a plurality of inclined surfaces arranged continuously at a position farther from the reference lines L1 and L2 than the reference line-proximate inclined surface 26A. In the illustrated example, the reference line-separated inclined surface 26C is a further ten inclined surfaces arranged continuously at a position farther from the reference lines L1 and L2 than the ten inclined surfaces 26A. In this case, a complex design can be expressed by the combination of the above-mentioned regions 131 and 132. Furthermore, if the above-mentioned region 132 provides the light incident on the unit optical element 13 with an optical effect similar to that of a lens having a Fresnel lens structure or an optical effect corresponding to the optical effect, the above-mentioned region 132 can also express a rich three-dimensional effect that is greater than the thickness of the decorative laminate 10. As a result, a richer three-dimensional effect that exceeds the thickness of the decorative laminate 10 can be more effectively expressed.

[0267] According to the above-described modified example, the decorative laminate 10 includes a shaping layer 20 and a brightness adjustment layer 30. The shaping layer 20 has a shaping surface 20a on which a concave-convex structure 25 is formed. The brightness adjustment layer 30 covers the shaping surface 20a. The decorative laminate 10 has at least one unit optical element 13. The unit optical element 13 reflects, refracts, and / or diffracts light incident on the front side surface 11 of the decorative laminate 10 according to the concave-convex structure 25. In the unit optical element 13, the shaping surface 20a includes a plurality of inclined surfaces 26A, 26C and a plurality of connecting surfaces 26B, 26D. The plurality of inclined surfaces 26A, 26C are aligned in a direction toward arbitrary reference lines L1, L2 extending along the normal direction Dn of the decorative laminate 10, and are inclined toward the reference lines L1, L2. The connection surfaces 26B and 26D connect the adjacent inclined surfaces 26A and 26C. The angles θA and θC of the inclined surfaces 26A and 26C with respect to the normal direction Dn are larger than the angles θB and θD of the connection surfaces 26B and 26D connected to the inclined surfaces 26A and 26C with respect to the normal direction Dn. In the cross section of the unit optical element 13 along the direction in which the multiple inclined surfaces 26A and 26C are arranged, the difference between the maximum and minimum values ​​of the angle of the reference line-close inclined surface 26C with respect to the normal direction Dn on one side of the reference lines L1 and L2 is greater than 1°. In the above cross section of the unit optical element 13, the difference between the maximum and minimum values ​​of the angle of the reference line-away inclined surface 26A with respect to the normal direction Dn on one side of the reference lines L1 and L2 is 1° or less. The reference line-close inclined surfaces 26C are multiple inclined surfaces arranged continuously at positions close to the reference lines L1 and L2. The reference line-separated inclined surfaces 26A are a plurality of inclined surfaces arranged continuously at a position farther from the reference lines L1, L2 than the reference line-proximate inclined surfaces 26C. In the illustrated example, the reference line-proximate inclined surfaces 26C are the 10 inclined surfaces closest to the reference lines L1, L2. The reference line-separated inclined surfaces 26A are further 10 inclined surfaces arranged continuously at a position farther from the reference lines L1, L2 than the 10 inclined surfaces 26C. In this case, the region 131 including the reference line-separated inclined surfaces 26A of the unit optical element 13 can provide the light incident on the unit optical element 13 with an optical effect similar to that of a cone or frustum-shaped lens or an optical effect corresponding to the optical effect. As a result, a rich three-dimensional effect that is greater than the thickness of the decorative laminate 10 can be expressed, and a rich design expression with a sense of luxury can be made possible.Also, it is possible to express a complex design by combining the above-mentioned regions 131 and 132. Furthermore, if the above-mentioned region 132 provides an optical effect to the light incident on the unit optical element 13 similar to that of a lens having a Fresnel lens structure or an optical effect corresponding to said optical effect, the above-mentioned region 132 can also express a rich three-dimensional effect that is greater than the thickness of the decorative laminate 10. As a result, it is possible to more effectively express a rich three-dimensional effect that is greater than the thickness of the decorative laminate 10.

[0269] According to the above-described modified example, the shaping surface 20a may include a flat surface or a curved surface between the reference lines L1, L2 and the reference line adjacent inclined surface 26A or 26C. In this case, a complex design can be expressed by combining the reference line adjacent inclined surface 26A and the flat surface or the curved surface.

[0270] According to the embodiment and its modified example described above, the angle of the connection surfaces 26B, 26D with respect to the normal direction Dn is 15° or more and 55° or less. In this case, the shape-imparting layer 20 can be formed with high precision, and the adhesion between the shape-imparting surface 20a and the brightness adjustment layer 30 is improved.

In addition, the concave-convex structure 25 can be formed with high precision.

[0273] According to the embodiment and the modified example thereof described above, the luminance adjustment layer 30 contains a pigment or a dye. In this case, the luminance adjustment layer 30 absorbs a part of the light incident on the decorative laminate 10, thereby adjusting the reflectance of visible light at the reflection interface between the luminance adjustment layer 30 and the shape-imparting layer 20 or another layer adjacent to the luminance adjustment layer 30 (the bonding layer 35 in the example shown in FIG. 26A).
