Description

[Technical Field] 【0001】 This disclosure relates to a decorative laminate, a decorative member, and a display system. [Background technology] 【0002】 As disclosed in Patent Document 1, display devices equipped with decorative sheets are widely used. When the display device is in the display state, the decorative sheet transmits the image light emitted by the display device, enabling transmitted image observation. When the display device is in the non-display state, the decorative sheet imparts aesthetic appeal to the object to which the display device is applied through the design displayed on the decorative sheet. For various purposes, there is a demand for the application of a surface layer containing a cured resin to such decorative sheets. [Prior art documents] [Patent Documents] 【0003】 [Patent Document 1] Japanese Patent Publication No. 2018-154036 【0004】 However, the surface layer is formed on a relatively thin base film. Decorative sheets are made by forming a design layer on a relatively thick base film. And it is not easy to form both the surface layer and the design layer on a single base film of either thin or thick thickness. 【0005】 Therefore, we considered creating a laminate by joining a first sheet containing a surface layer and a second sheet containing a design layer with a bonding layer.

[Modes for carrying out the invention] 【0018】 Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Note that, for the sake of illustration and ease of understanding, the scale and aspect ratios of the drawings attached to this specification have been appropriately altered and exaggerated from those of the actual objects. 【0019】 In this specification, terms such as "perpendicular" and "identical," as well as values ​​of length and angle, which specify shape, geometric conditions, and their degree, shall not be limited to their strict meaning, but shall be interpreted to include a range that can be expected to function similarly. 【0020】 In this specification, the terms "sheet" and "film" are not distinguished from each other solely on the basis of name differences. For example, "first sheet" is not distinguished from a component called "first film" solely on the basis of name differences. For example, "first base film" is not distinguished from a component called "first base sheet" solely on the basis of name differences. 【0021】 To clarify directional relationships between drawings, some drawings use arrows common to all drawings to indicate the first direction DA, the second direction DB, and the third direction DC. Arrows pointing towards the back of the drawing, perpendicular to the plane of the drawing, are indicated by a symbol of an "x" inside a circle, as shown in Figure 2, for example. Arrows pointing towards the front of the drawing, perpendicular to the plane of the drawing, are indicated by a symbol of a dot inside a circle, as shown in Figure 3, for example. 【0022】 As used herein, "transparent" means a visible light transmittance of 50% or more, preferably 80% or more. A haze meter conforming to JIS K 7361 (manufactured by Murakami Color Technology Laboratory, product number: HM-150) is used to determine the visible light transmittance. 【0023】 Figure 1 is a schematic exploded perspective view showing an example of the display system 1. The display system 1 can be applied to various uses. The display system 1 may be applied to the interior or exterior of a mobile body, which is a movable device. A mobile body is a movable device. Examples of mobile bodies include automobiles, ships, airplanes, etc. As a specific example, the display system 1 may be applied to the interior or exterior of an automobile. The display system 1 may be applied to the interior of a building, such as walls, doors, ceilings, etc. The display system 1 may be applied to various devices such as furniture and home appliances. 【0024】 The display system 1 shown in Figure 1 includes a display device 10 and a decorative laminate 20 superimposed on the display device 10. The display system 1 may also include a decorative member 30 instead of the decorative laminate 20. The decorative member 30 includes the decorative laminate 20 and a support portion 35. The display system 1 according to this embodiment incorporates features to improve the scratch resistance of the decorative laminate. 【0025】 As shown in Figure 1, the display device 10 extends in a first direction DA and a second direction DB perpendicular to the first direction DA. The decorative laminate 20 also extends in the first direction DA and the second direction DB. As shown in Figure 2, the display device 10 and the decorative laminate 20 are stacked in a third direction DC. In this respect, the third direction DC is the stacking direction. The third direction DC is perpendicular to both the first direction DA and the second direction DB. 【0026】 The display system 1 is observed from a position away from the display system 1 in a third direction DC. When the observer observes the display system 1, the display device 10 is further away from the observer in the third direction DC than the decorative laminate 20 superimposed on the display device 10. When the observer observes the display system 1, the decorative laminate 20 is located between the observer and the display device 10 in the third direction DC. 【0027】 The display device 10 emits image light when in display mode. An image can be displayed by the emission of image light. The display device 10 stops emitting image light when in non-display mode. Various devices may be used as the display device 10. The display device 10 includes a display surface 11 facing the decorative laminate 20 in a third direction DC. The display surface 11 extends in a first direction DA and a second direction DB. In the illustrated example, the display surface 11 has a rectangular shape. The display surface 11 may be flat or curved. 【0028】 The image displayed by the display device 10 may be a still image or a moving image. The display device 10 may also be a dot-matrix display device. A dot-matrix display device has multiple pixels that form each dot. In this display device, a desired image can be displayed on the display surface by controlling the light emission state of each pixel. Examples of dot-matrix display devices include liquid crystal displays and electroluminescent displays, also known as EL displays. 【0029】 As shown in Figures 1 and 2, the display device 10 may include a transmissive display panel 12 and a surface light source device 13 that illuminates the display panel 12 from the back. A liquid crystal display panel is an example of the transmissive display panel 12. Various devices such as edge-lit or direct-lit surface light sources may be used as the surface light source device 13. 【0030】 In the examples shown in Figures 1 and 2, the decorative laminate 20 is a sheet-like member. As viewed from the observer, the decorative laminate 20 is provided so as to cover the display surface 11. In the illustrated examples, the decorative laminate 20 is flat. Unlike the illustrated examples, the decorative laminate 20 may also be curved. The decorative laminate 20 includes a first surface 20a and a second surface 20b opposite to the first surface 20a. The first surface 20a and the second surface 20b extend in the first direction DA and the second direction DB, respectively. The first surface 20a and the second surface 20b face each other in the third direction DC. The second surface 20b faces the display surface 11 of the display device 10 in the third direction DC. In the third direction DC, the second surface 20b is located between the first surface 20a and the display surface 11 of the display device 10. 【0031】 The thickness of the decorative laminate 20 may be 150 μm or more, or 200 μm or more. The thickness of the decorative laminate 20 may be 500 μm or less, or 400 μm or less. 【0032】 The decorative laminate 20 has a pencil hardness of F or higher on its first surface 20a. The decorative laminate 20 may also have a pencil hardness of H or higher on its first surface 20a, or it may have a pencil hardness of 2H or higher. 【0033】 In this specification, pencil hardness is determined as follows using a pencil hardness tester conforming to JIS-K5600-5-4. Using this pencil hardness tester, a pencil with a specified hardness (manufactured by Mitsubishi Pencil Co., Ltd., product name: uni) is pressed against the surface of the sample to be measured with a tip load of 750g, and it is evaluated whether scratches or indentations occur. For each hardness, the above evaluation is performed five times, and the hardest hardness for which neither scratches nor indentations are observed even once is identified as the pencil hardness of the sample to be measured. 【0034】 The decorative laminate 20 includes a first sheet 21, a second sheet 22 superimposed on the first sheet 21, and a bonding layer 23 that joins the first sheet 21 and the second sheet 22. The first sheet 21 forms the first surface 20a of the decorative laminate 20. The second sheet 22 forms the second surface 20b of the decorative laminate 20. That is, the second sheet 22 faces the display surface 11 of the display device 10. The bonding layer 23 is located between the first sheet 21 and the second sheet 22 in a third direction DC. 【0035】 The first sheet 21, the second sheet 22, and the bonding layer 23 are all capable of transmitting image light emitted by the display device 10. As a result, when the display device 10 is in the display state, an observer can observe the image displayed by the display device 10. In other words, the first sheet 21, the second sheet 22, and the bonding layer 23 all have visible light transmittance to the extent that it enables the transmission and observation of the image. 【0036】 The first sheet 21 includes a first base film 24 and a surface layer 25 superimposed on the first base film 24. In the example shown in Figure 2, the first base film 24 and the surface layer 25 are superimposed on each other in the third direction DC. The surface layer 25 forms the first surface 20a of the decorative laminate 20. The first base film 24 is located between the surface layer 25 and the bonding layer 23 in the third direction DC. 【0037】 In the example shown in Figure 2, the first base film 24 is a film that extends in the first direction DA and the second direction DB. The first base film 24 supports the surface layer 25. In the illustrated example, the first base film 24 is transparent. Various films can be used as the first base film 24. Examples of resins that can be used as the material for the first base film 24 include polymethyl methacrylate, polyethylene terephthalate, polyethylene naphthalate, polycarbonate, polystyrene, cyclic polyolefin, ABS (acrylonitrile butadiene styrene copolymer), and TAC (triacetylcellulose). The thickness of the first base film 24 may be 40 μm or more, or 50 μm or more. The thickness of the first base film 24 may be less than 100 μm, or less than 75 μm. 【0038】 In the example shown in Figure 2, the thickness of the first base film 24 is smaller than the thickness of the second base film 26 of the second sheet 22, which will be described later. The thickness of the first base film 24 may be 10% or more and 80% or less of the thickness of the second base film 26. 【0039】 The surface layer 25 is superimposed on the first base film 24. The surface layer 25 forms the first surface 20a of the decorative laminate 20. In the example shown in Figure 2, the surface layer 25 is superimposed on the first base film 24 from the third direction DC. The surface layer 25 is furthest from the display device 10 in the third direction DC. 【0040】 The surface layer 25 contains a cured resin. The cured resin is a cured product of a curable resin composition. Examples of cured products of curable resin compositions include cured products of thermosetting resin compositions and cured products of ionizing radiation-curable resin compositions. 【0041】 A thermosetting resin composition is a composition containing at least a thermosetting resin, and is a resin composition that hardens upon heating. Examples of thermosetting resins include acrylic resins, urethane resins, phenolic resins, urea-melamine resins, epoxy resins, polyester resins, and silicone resins. In addition to these thermosetting resins, a curing agent and a curing catalyst may be added to the thermosetting resin composition as needed. 【0042】 Examples of ionizing radiation-curable resin compositions include electron beam-curable resin compositions and ultraviolet-curable resin compositions. Electron beam-curable resin compositions are superior in that they do not require polymerization initiators, resulting in less odor and less susceptibility to discoloration. 【0043】 An ionizing radiation-curable resin composition is a composition containing a compound having an ionizing radiation-curable functional group (hereinafter also referred to as "ionizing radiation-curable compound"). An ionizing radiation-curable functional group is a group that crosslinks and hardens upon irradiation with ionizing radiation. Examples of ionizing radiation-curable functional groups include functional groups having an ethylenically double bond, such as (meth)acryloyl groups, vinyl groups, and allyl groups. Examples of ionizing radiation-curable functional groups include epoxy groups and oxetanyl groups. Ionizing radiation refers to electromagnetic waves or charged particle beams that have energy quanta capable of polymerizing or crosslinking molecules. Examples of ionizing radiation include ultraviolet rays (UV) and electron beams (EB). Examples of ionizing radiation include electromagnetic waves such as X-rays and gamma rays, and charged particle beams such as alpha rays and ion beams. 【0044】 When the ionizing radiation-curable compound is an ultraviolet-curable compound, the ionizing radiation-curable resin composition may contain additives such as photopolymerization initiators and photopolymerization accelerators. The photopolymerization initiator may be one or more selected from acetophenone, benzophenone, α-hydroxyalkylphenone, Michler ketone, benzoin, benzyldimethyl ketal, benzoylbenzoate, α-acyloxime ester, thioxanthone, etc. The photopolymerization accelerator can reduce polymerization inhibition by air during curing and accelerate the curing rate. The photopolymerization accelerator may be one or more selected from, for example, p-dimethylaminobenzoate isoamyl ester, p-dimethylaminobenzoate ethyl ester, etc. 【0045】 The surface layer 25 can be manufactured, for example, as follows: First, a curable resin composition for forming the surface layer 25 is applied to the first base film 24 to form a coating film. Next, the coating film is dried. Then, the coating film is cured to form a cured resin. In this way, a surface layer 25 containing a cured resin can be manufactured on the first base film 24. 【0046】 The pencil hardness of the first sheet alone on the surface formed by the surface layer 25 may be F or higher, H or higher, or 2H or higher. The pencil hardness of the first sheet alone refers to the pencil hardness of the first sheet 21 separated from the second sheet 22 and the bonding layer 23. 【0047】 In the example shown in Figure 2, the surface layer 25 includes a low-reflection layer 251. In this example, the first sheet 21 is an optical sheet. The low-reflection layer 251 can suppress the reflection of ambient light incident on the first sheet 21. The refractive index of the low-reflection layer 251 may be lower than the refractive index of other adjacent layers of the first sheet 21 in the third direction DC. In the illustrated example, the refractive index of the low-reflection layer 251 is lower than the refractive index of the first substrate film 24. The low-reflection layer 251 may contain particles for adjusting the refractive index, such as hollow silica and fluorine additives. The thickness and refractive index of the low-reflection layer 251 can be appropriately selected depending on the wavelength of light whose reflection should be suppressed. The thickness of the low-reflection layer may be between 80 nm and 130 nm. 【0048】 The surface layer 25 is not limited to the low-reflection layer 251, but may also include other layers expected to perform specific functions. For example, as shown in Figure 5, the surface layer 25 may include an anti-glare layer 252 having an anti-glare function. In this example, the first sheet 21 is an optical sheet. In the illustrated example, the anti-glare layer 252 includes a binder resin 252a and fine particles 252b dispersed in the binder resin 252a. The binder resin may include a cured resin, which is a cured product of a curable resin composition. The fine particles 252b may be various fine particles such as silica fine particles, acrylic fine particles, styrene fine particles, or fine particles with voids. The anti-glare layer 252 may contain one type of these fine particles alone, or two or more types. The thickness of the anti-glare layer may be 1 μm or more and 10 μm or less. 【0049】 The anti-glare layer 252 may have an uneven surface. According to the specific example shown in Figure 5, the anti-glare layer 252 can diffusely reflect ambient light incident on the first sheet 21 at its uneven surface. This reduces the reflection of external images on the first surface 20a in the decorative laminate 20 including the first sheet 21. In the example shown in Figure 5, the uneven surface of the anti-glare layer 252 is formed by fine particles 252b protruding from the binder resin 252a. Unlike the example shown in Figure 5, the fine particles 252b may be dispersed within the binder resin 252a, and light may be diffused at the interface between the fine particles 252b and the binder resin 252a. 【0050】 Furthermore, the surface layer 25 may also include a hard coat layer 253. The hard coat layer 235 contains a cured resin, which is a cured product of a curable resin composition. The hard coat layer 253 may have a higher hardness than the first base film 24, for example, a higher Vickers hardness than the first base film 24. The thickness of the hard coat layer 253 may be 1 μm or more and 10 μm or less. 【0051】 As described above, the first sheet 21 included a first base film 24 and a surface layer 25. The first sheet 21 may also include layers other than the first base film 24 and the surface layer 25. For example, the first sheet 21 may include a primer layer located between the first base film 24 and the surface layer 25. 【0052】 The second sheet 22 displays the design. When the display device 10 is not displayed, an observer can observe the design of the second sheet 22. The second sheet 22 may also be referred to as a decorative sheet. 【0053】 To ensure the visibility of the image displayed by the display device 10, the visible light transmittance of the second sheet 22 may be 10% or more, or 30% or more. To enable rich design expression with the second sheet 22, the visible light transmittance of the second sheet 22 may be 80% or less, or 50% or less. The visible light transmittance is determined as described above. The visible light transmittance of the second sheet 22 is measured for the second sheet 22 separated from the first sheet 21 and the bonding layer 23. 【0054】 The second sheet 22 includes a second base film 26 and a design layer 27 superimposed on the second base film 26. In the example shown in Figure 2, the second base film 26 and the design layer 27 are superimposed on each other in the third direction DC. The design layer 27 is located between the second base film 26 and the bonding layer 23 in the third direction DC. Unlike the illustrated example, the second base film 26 may be located between the design layer 27 and the bonding layer 23 in the third direction DC. 【0055】 In the example shown in Figure 2, the second base film 26 is a film-like member that extends in the first direction DA and the second direction DB. The second base film 26 supports the design layer 27. The second base film 26 may have a visible light transmittance of 10% to 95%. Various films can be used as the second base film 26. Examples of materials for the second base film 26 include polymethyl methacrylate, polyethylene terephthalate, polyethylene naphthalate, polycarbonate, polystyrene, cyclic polyolefin, and resins such as ABS (acrylonitrile butadiene styrene copolymer). The thickness of the second base film 26 may be 100 μm or more, or 300 μm or more. The thickness of the second base film 26 may be 125 μm or less, or 250 μm or less. 【0056】 In the example shown in Figure 2, when the first sheet 21 and the second sheet 22 are stacked, the second base film 26 forms the second surface 20b of the decorative laminate 20. That is, the second base film 26 faces the display surface 11 of the display device 10 in the third direction DC. 【0057】 The design layer 27 displays designs such as figures, patterns, designs, colors, pictures, photographs, characters, marks, pictograms, letters, and numbers. The design layer 27 can also display a background design. For example, the design layer 27 may display wood grain or marble patterns, metallic textures, geometric patterns, etc., as a design that can harmonize the surrounding environment in which the display system 1 is installed with the decorative laminate 20. The design layer 27 can be formed on the second base film 26, for example, by printing or transfer. The thickness of the design layer 27 may be 1 μm or more and 10 μm or less. 【0058】 The design layer 27 includes a colorant and a base material for dispersing the colorant. Various pigments, including pearl pigments, or dyes may be used as the colorant in the design layer. Examples of base materials for the design layer 27 include acrylic resins such as polymethyl methacrylate, polyurethane resins, vinyl chloride-vinyl acetate copolymers, vinyl chloride-vinyl acetate-acrylic copolymers, chlorinated polypropylene resins, polyester resins, polyamide resins, butyral resins, polystyrene resins, nitrocellulose resins, and cellulose acetate resins. The design layer 27 may contain one of these materials alone or two or more of them. 【0059】 As described above, the second sheet 22 included the second base film 26 and the design layer 27. The second sheet 22 may also include layers other than the second base film 26 and the design layer 27. 【0060】 In the examples shown in Figures 1 and 2, the bonding layer 23 is located between the first sheet 21 and the second sheet 22 in the third direction DC. The bonding layer 23 bonds the first sheet 21 and the second sheet 22 which are stacked on top of each other. The bonding layer 23 bonds the first sheet 21 and the second sheet 22. 【0061】 The bonding layer 23 may be formed of a resin. The resin forming the bonding layer 23 may include various resins such as polyester resin, acrylic resin, urethane resin, polyolefin resin, epoxy resin, and polyether resin. The bonding layer 23 may also include a thermoplastic resin. The bonding layer 23 may also include a curing resin. 【0062】 The cured resin is a cured product of a curable resin composition. Examples of the cured product of the curable resin composition include the cured product of a thermosetting resin composition and the cured product of an ionizing radiation-curable resin composition. The cured resin used for the bonding layer 23 may be the above-described cured resin used for the surface layer 25. The cured resin constituting the bonding layer 23 can be formed by curing a layer of a curable resin composition positioned between the first sheet 21 and the second sheet 22. The curable resin composition may be cured by various methods. The curable resin composition may be cured, for example, by irradiation with ionizing radiation such as ultraviolet rays or electron beams. The curable resin composition may be cured by heating. 【0063】 The operation of the illustrated display system 1 will be described. 【0064】 When the display device 10 is in the display state, image light is emitted from the display surface 11. The image light emitted from the display surface 11 passes through the decorative laminate 20. As shown in FIG. 3, the observer can observe the image formed on the display surface 11 by the image light that has passed through the decorative laminate 20. In the example shown in FIG. 3, marks representing the air volume and the ejection port in an automobile air conditioner are displayed. 【0065】 Preferably, the color tone of the image observed through the decorative laminate 20 matches the color tone of the image displayed by the display device 10. That is, it is preferable to suppress the change in the color tone of the image due to the passage of the image light through the decorative laminate 20. For this reason, it is preferable that the chroma of the decorative laminate 20 is low. Specifically, L * a * b * Reducing the absolute value of the transmission chromaticity a in the L * a*b* color system, and reducing the absolute value of the transmission chromaticity b * in the L * a * b * a*b* color system is effective. Preferably, the color of the design displayed by the decorative laminate 20 is adjusted so that the absolute value of the transmission chromaticity a * in the L* a * b * Transmittance b in a color system * The color of the design displayed by the decorative laminate 20 is adjusted so that the absolute value of is 4 or less, more preferably 2 or less. 【0066】 The above L * a * b * Transmittance a in a color system * The value of the transparency chromaticity b * The value of is measured using a spectrophotometer (manufactured by JASCO, product number: V-670) with the decorated laminate 20 facing the observer, using light transmitted in the third direction DC. 【0067】 When the display device 10 is in a non-display state, the decorative laminate 20 covering the display surface 11 is visible, as shown in Figure 4. The observer observes the design displayed by the decorative laminate 20 (second sheet 22). The design expression of the decorative laminate 20 allows the display device 10 to be installed while ensuring harmony and unity with the surrounding environment. Recently, the range of applications for the display device 10 has been rapidly expanding, and by using the decorative laminate 20, the display device 10 can be applied to car interiors, building interiors, furniture, home appliances, etc., where design is important. 【0068】 Incidentally, the application of a surface layer using a cured resin to the front surface of the decorative sheet is being considered. By using a cured resin, various functions can be imparted to the surface layer. For example, a hard coat layer containing a cured resin is being considered for use as the surface layer of the decorative sheet in order to provide scratch resistance. An anti-reflective layer containing a cured resin is being considered to be applied to the decorative sheet. An anti-glare layer containing a cured resin is being considered to be applied to the decorative sheet. 【0069】 However, the optimal thickness of the base film for forming the surface layer differs from the optimal thickness of the base film for forming the design layer. The surface layer is formed on a relatively thin base film, while the design layer is formed on a relatively thick base film. Attempting to form the design layer on a relatively thin base film can lead to problems where the base film cannot stably support the design layer. Conversely, attempting to form the surface layer on a relatively thick base film can lead to problems where the uneven surface of the base film makes it difficult to uniformly apply the curable resin composition forming the surface layer onto the base film. 【0070】 To address these problems, the inventors considered fabricating a first sheet and a second sheet by layering a surface layer and a design layer on separate base films, and then joining the first and second sheets. This method allows for the fabrication of the surface layer and design layer while avoiding the aforementioned problems. However, a decorative laminate containing the first sheet, joining layer, and second sheet in this order could result in another problem. Specifically, the scratch resistance of the first surface formed by the surface layer of the first sheet was sometimes insufficient. The pencil hardness of the first surface of a decorative laminate exhibiting this problem was significantly lower than the pencil hardness of the surface formed by the surface layer of the first sheet alone. In other words, the pencil hardness of the first sheet on the surface formed by the surface layer decreased significantly after joining it to the second sheet to create the decorative laminate, compared to before joining it to the second sheet. As a result, the scratch resistance of the first surface of the decorative laminate was inferior to the expected level. 【0071】 Based on this, in this embodiment, the pencil hardness of the first surface 20a of the decorative laminate 20 is set to F or higher. The first surface 20a is formed by the surface layer 25 of the first sheet 21. In this specific example, the pencil hardness of the first surface 20a of the decorative laminate 20, formed by the surface layer 25 of the first sheet 21, remains sufficiently high even after the first sheet 21 is bonded to the second sheet 22. As a result, the decorative laminate 20 can improve scratch resistance while achieving design expression by the decorative sheet (second sheet 22) and various functions by the sheet including the surface layer (first sheet 21). 【0072】 To achieve a pencil hardness of F or higher on the first surface 20a of the decorative laminate 20, the pencil hardness of the first sheet alone may be increased beforehand. Furthermore, as will be described later, the pencil hardness of the first surface 20a of the decorative laminate 20 can be made F or higher by adjusting the materials constituting the bonding layer 23. 【0073】 Further investigation by the inventors into the cause of the aforementioned decrease in pencil hardness in the first sheet 21 yielded the following findings. External forces applied to the decorative laminate 20 from the surface layer 25 are transmitted not only to the first sheet 21 but also to the bonding layer 23 via the first sheet 21. Anticipating that the bonding layer 23 would be more easily deformed than the first sheet 21 and the second sheet 22, the inventors adjusted the hardness of the bonding layer 23 in its standalone state. Improving the hardness of the bonding layer 23 in its standalone state prevented a significant decrease in the pencil hardness of the first surface 20a of the decorative laminate 20 compared to the pencil hardness of the surface layer 25 of the first sheet 21 in its standalone state before bonding with the bonding layer 23 and the second sheet 22. 【0074】 From this perspective, the resin contained in the bonding layer 23 may be a curing resin. By using a curing resin in the bonding layer 23, the pencil hardness of the first surface 20a of the decorative laminate 20 could be improved. By using a bonding layer 23 containing a curing resin, it was possible to suppress the decrease of three or more levels in the pencil hardness of the first surface 20a of the decorative laminate 20 from the pencil hardness of the surface layer 25 of the first sheet 21 in its standalone form before bonding with the bonding layer 23 and the second sheet 22. As a result, sufficient scratch resistance could be provided to the decorative laminate 20. 【0075】 Furthermore, the cured resin's softening is suppressed regardless of the temperature rise. As a result, even when the decorative laminate 20 is heated for molding or other purposes, delamination between the first sheet 21 and the bonding layer 23, or between the second sheet 22 and the bonding layer 23, can be suppressed. Therefore, the bonding state between the first sheet 21 and the second sheet 22 can be stably maintained. 【0076】 The pencil hardness of the first surface 20a of the decorative laminate 20 may be set to a pencil hardness two steps lower or higher than the pencil hardness of the surface formed by the surface layer 25 of the first sheet 21. The pencil hardness of the first surface 20a of the decorative laminate 20 may be set to a pencil hardness one step lower or higher than the pencil hardness of the surface formed by the surface layer 25 of the first sheet 21. The pencil hardness of the first surface 20a of the decorative laminate 20 may be set to a pencil hardness equal to or higher than the pencil hardness of the surface formed by the surface layer 25 of the first sheet 21. The pencil hardness of the surface formed by the surface layer 25 of the first sheet 21 refers to the pencil hardness of the surface of the first sheet 21 as a standalone unit before it is joined with the bonding layer 23 and the second sheet 22. According to this example, a significant decrease in the pencil hardness of the first surface 20a of the decorative laminate 20 from the pencil hardness of the surface layer 25 of the first sheet 21 as a standalone unit before it is joined with the bonding layer 23 and the second sheet 22 is suppressed. As a result, the first surface 20a of the decorative laminate 20 has the intended pencil hardness and can exhibit the expected scratch resistance. 【0077】 The thickness of the first base film 24 may be less than 100 μm. In this example, variations in the thickness of the first base film 24 are suppressed. This allows the surface layer 25 to be easily overlaid on the surface of the first base film 24. Therefore, according to this specific example, the first sheet 21 can be manufactured stably. 【0078】 By making the thickness of the first base film 24 less than 100 μm, the curing conditions for the bonding layer 23 can be controlled via the first sheet 21. For example, when the curable resin composition includes an ionizing radiation-curable resin composition, when ionizing radiation is irradiated onto the ionizing radiation-curable resin composition via the first sheet 21, the absorption of ionizing radiation by the first base film 24 is reduced. This allows for a reduction in the exposure time or exposure intensity of the ionizing radiation. When the curable resin composition includes a thermosetting resin composition, the absorption of heat by the first base film 24 is reduced. Therefore, the heating temperature or heating time can be reduced. In this way, by forming the bonding layer 23 under less harsh conditions, the decorative laminate 20 can be stably manufactured. 【0079】 The thickness of the second base film 26 may be between 100 μm and 300 μm. In this specific example, the second base film 26 can properly support the design layer 27. This allows for the stable production of the decorative laminate 20. 【0080】 The design layer 27 is located between the second base film 26 and the bonding layer 23. In this specific example, the design layer 27 can be protected by other components of the decorative laminate 20. This allows the decorative laminate 20 to stably display the design formed by the design layer 27. 【0081】 In the embodiment described above, the decorative laminate 20 includes a first sheet 21, a second sheet 22 superimposed on the first sheet 21, and a bonding layer 23 that joins the first sheet 21 and the second sheet 22. The first sheet 21 includes a first base film 24 and a surface layer 25 superimposed on the first base film 24. The second sheet 22 includes a second base film 26 and a design layer 27 superimposed on the second base film 26. The surface layer 25 of the first sheet 21 contains a curing resin and forms a first surface 20a, which is one surface of the decorative laminate 20. In this decorative laminate 20, the pencil hardness of the first surface 20a formed by the surface layer 25 may be F or higher. In this decorative laminate 20, the pencil hardness of the first surface 20a of the decorative laminate 20 may be two levels lower than or equal to the pencil hardness of the surface formed by the surface layer 25 of the first sheet 21. 【0082】 According to this embodiment, the pencil hardness on the surface of the first sheet 21 before bonding with the bonding layer 23 and the second sheet 22 is maintained without significant decrease on the first surface 20a formed by the first sheet 21 of the decorative laminate 20. Therefore, the scratch resistance on the surface of the first sheet 21 before bonding with the bonding layer 23 and the second sheet 22 is maintained without significant decrease on the first surface 20a formed by the first sheet 21 of the decorative laminate 20. In other words, the decorative laminate 20, including the surface layer 25 and the design layer 27, has sufficient scratch resistance. 【0083】 Although one embodiment has been described with reference to specific examples, the above-mentioned example does not limit the embodiment. The above-described embodiment can be implemented in various other examples, and various omissions, substitutions, modifications, and additions can be made without departing from its essence. 【0084】 In the specific example described above, the surface layer 25 included a low-reflection layer 251. However, the surface layer 25 is not limited to this and may further include layers other than the low-reflection layer 251. For example, as shown in Figure 6, the surface layer 25 may include a low-reflection layer 251 and a hard coat layer 253. In this specific example, the low-reflection layer 251 is superimposed on the first substrate film 24 via the hard coat layer 253. The hard coat layer 253 is located between the first substrate film 24 and the low-reflection layer 251 in the third direction DC. 【0085】 Alternatively, as shown in Figure 7, the surface layer 25 may include a low-reflection layer 251 and an anti-glare layer 252. In this specific example, the low-reflection layer 251 is superimposed on the first base film 24 via the anti-glare layer 252. The anti-glare layer 252 is located between the first base film 24 and the low-reflection layer 251 in the third direction DC. 【0086】 As shown in Figure 6, the multiple low-reflection layers 251 may be provided spaced apart from each other in the first direction DA. The first surface 20a of the decorative laminate 20 is formed by the low-reflection layers 251 in the portions where the low-reflection layers 251 are provided. The first surface 20a is formed by the hard coat layer 253 in the portions where the low-reflection layers 251 are not provided. The positions where the low-reflection layers 251 are provided may correspond to the positions where the display device 10 is provided. 【0087】 In the specific example described above, the display device 10 and the decorative laminate 20 are shown to have the same dimensions, but the system is not limited to this. As shown in Figure 6, the decorative laminate 20 may have dimensions greater than or equal to the dimensions of the display device 10. In this example as well, the decorative laminate 20 conceals the display device 10. Furthermore, the decorative laminate 20 may be stacked on top of multiple display devices 10. In the illustrated example, the decorative laminate 20 is stacked on two display devices 10 that are separated from each other in the first direction DA. In other words, the display system 1 may include multiple display devices 10. 【0088】 In the specific example described above, the surface layer 25 included a single layer of low-reflection layer 251. However, it is not limited to this, and as shown in Figure 8, the low-reflection layer 251 may include a low-refractive-index layer 251a and a high-refractive-index layer 251b with a higher refractive index than the low-refractive-index layer 251a. In the illustrated example, the low-refractive-index layer 251a and the high-refractive-index layer 251b are arranged in a repeating order in the third direction DC from the first surface 20a of the decorative laminate 20. It is not limited to this example, and the low-refractive-index layer 251 may include one low-refractive-index layer 251a and one high-refractive-index layer 251b. The low-refractive-index layer 251a may include particles such as hollow silica and fluorine additives for adjusting the refractive index. The high-refractive-index layer 251b may include particles such as high-refractive-index fillers for adjusting the refractive index. 【0089】 In the specific example described above, the anti-glare layer 252 had an uneven surface, but is not limited to this. As shown in Figure 7, the anti-glare layer 252 may have a flat plate shape. The anti-glare layer 252 may diffuse ambient light incident on the decorative laminate 20 from the first surface 20a within the fine particles 252b dispersed in the binder resin 252a. 【0090】 In the specific example described above, the decorative laminate 20 had a flat plate shape, but it is not limited to this. As shown in Figure 9, the decorative laminate 20 may have a three-dimensional shape. In the illustrated example, the decorative laminate 20 is plastically deformed by molding. The decorative laminate 20 may be deformed by various molding methods such as insert molding, vacuum forming, pressure forming, and TOM molding. TOM molding is a Three-Dimensional Overlay Method and can also be called three-dimensional surface decorative molding. In the illustrated example, the decorative laminate 20 is bent at both edges in the first direction DA. By giving the decorative laminate 20 a three-dimensional shape that can be used for various applications, the range of applications for the decorative laminate 20 can be expanded. 【0091】 In the specific example described above, the display system 1 is configured by stacking the decorative laminate 20 on the display device 10, but it is not limited to this. As shown in Figures 10 and 11, the display system may also be configured by stacking the decorative member 30 on the display device 10. Such a display system 1 includes the display device 10 and the decorative laminate 20. 【0092】 The decorative member 30 includes a decorative laminate 20 and a support portion 35 joined to the decorative laminate 20. As shown in Figure 2, in the decorative member 30, the decorative laminate 20 and the support portion 35 are stacked in the third direction DC. 【0093】 The support portion 35 reinforces the decorative laminate 20. Glass or resin materials can be used as the material constituting the support portion 35. Examples of resin materials include polycarbonate, acrylic resins such as polymethyl methacrylate, and ABS (acrylonitrile butadiene styrene copolymer). The support portion 35 may be joined to the decorative laminate 20 via an adhesive layer 36. The support portion 35 may also be joined to the decorative laminate 20 by welding. 【0094】 In the example shown in Figure 10, the design layer 27 of the second sheet 22 is located between the second base film 26 and the bonding layer 23. In this specific example, when the decorative laminate 20 and the support part 35 are joined, the decorative laminate 20 comes into contact with the support part 35 at a component other than the design layer 27, namely the second base film 26 in Figure 10. This makes it possible to suppress damage to the design layer 27 when joining the decorative laminate 20 and the support part 35. 【0095】 The decorative member 30 may be manufactured by injection molding a decorative laminate 20 housed in the cavity of a mold. In this example, the support portion 35 may also be a molded portion 37 formed by injection molding. During injection molding, the decorative laminate 20 is welded to the support portion 35, which is a molded portion 37 made of injection resin. As a result, a decorative member 30 is obtained having a support portion 35 made of a molded portion 37 and a decorative laminate 20. Examples of materials constituting the molded portion 37 include polycarbonate, acrylic resins such as polymethyl methacrylate, and thermoplastic resins such as ABS (acrylonitrile butadiene styrene copolymer). 【0096】 The injection molding process for producing the decorative member 30 may be in-mold molding, which involves deformation of the decorative laminate 20 during molding. Alternatively, the decorative laminate 20 may be pre-molded, and the pre-molded decorative laminate 20 may be insert-molded. Examples of pre-molding include vacuum forming and pressure forming. In addition, to ensure close contact between the decorative laminate 20 and the support portion 35 during injection molding, an adhesive layer 36, such as a heat seal layer, may be provided between the support portion 35 and the decorative laminate 20. 【0097】 In the manufacturing of the decorative member 30, the decorative laminate 20 may be applied to TOM molding. By TOM molding, the decorative laminate 20 can be bonded to a support portion 35 having a three-dimensional shape. An adhesive layer 36, such as a heat seal layer, may be provided between the support portion 35 and the decorative laminate 20. 【0098】 In the above, we have described several modifications of a specific example of the embodiment described above, but it is also possible to combine and apply multiple modifications as appropriate. [Examples] 【0099】 An embodiment of this disclosure will be described in more detail below using examples, but this disclosure is not limited to this embodiment. 【0100】 Decorative laminates according to Examples 1-3, decorative laminates according to Comparative Examples 1-3, and a first sheet used in <Evaluation 4> described later were prepared.

The evaluation results are shown in the Evaluation 1 column of Table 1. No distortion was observed in the first base film of the decorated laminate according to the example marked with "〇" and the decorated laminate according to the comparative example. Regarding the decorative laminate related to Comparative Example 2, which was marked with "×", distortion was confirmed in the first base film. 【0117】 <Rating 2> Double-sided tape having the same dimensions as the decorative laminates obtained in Examples 1-3 and Comparative Examples 1-3 was attached to each decorative laminate from the second surface, and the decorative laminate was fixed to a flat base via the double-sided tape. Next, cuts were made in the fixed decorative laminate from the first surface to the second surface using a utility knife to create 25 squares of 2 mm each. Then, cellophane tape (CT24, manufactured by Nichiban Co., Ltd.) was applied to the first surface to cover the created squares, and then peeled off. The presence or absence of squares where the first sheet had peeled away from the second sheet was checked using the cellophane tape. The evaluation results are shown in the Evaluation 2 column of Table 1. In the case of the decorated laminate according to the example in which "〇" was marked, and the decorated laminate according to the comparative example, the decorated laminate remained on the base in all squares. For the decorated laminate according to Comparative Example 1, which was marked with "×", we confirmed the squares where the first sheet had been peeled off from the second sheet with cellophane tape. 【0118】 <Rating 3> For the decorated laminates obtained in Examples 1-3 and Comparative Example 3, a pencil (Mitsubishi Pencil Co., Ltd., product name: uni) was brought into contact with the first surface using a pencil hardness tester conforming to JIS-K5600-5-4 with a tip load of 750g, and it was visually checked whether scratches or indentations occurred. Five evaluations were performed for each pencil hardness, and the hardest pencil hardness was determined from among those in which neither scratches nor indentations were observed.

A flat polycarbonate sheet with dimensions of 100 mm x 100 mm was prepared as the resin material to form the support part. The decorative laminate and the resin material to form the support part were placed in the chamber of the molding machine. In the chamber of the molding machine, the central part of the second surface of the decorative laminate and the polycarbonate sheet to form the support part were placed facing each other. The chamber of the molding machine was divided into a first chamber and a second chamber by the decorative laminate. The polycarbonate sheet to form the support part was placed in the first chamber. The resin material to form the support part was not placed in the second chamber. The first and second chambers were depressurized. The decorative laminate was heated for 80 seconds. When the temperature of the decorative laminate reached 130°C, the second chamber was pressurized to atmospheric pressure (101.3 kPa). Under the pressure of the second chamber, the decorative laminate covered the support portion from the second surface. In this way, the decorative member was manufactured using a molding machine. The manufactured decorative member was removed from the molding machine, and it was checked for delamination between the decorative laminate and the support portion, and for any cracks in the adhesive layer. For the decorated laminates in the examples and comparative examples marked with "〇", no peeling from the support portion or cracking of the adhesive layer was observed. Regarding the decorative laminate according to Example 3, which is marked with "×", a portion that had peeled off from the support was observed. In addition, cracks were observed in the adhesive layer. This evaluation could not be performed on the decorated laminates related to Comparative Example 1 and Comparative Example 2, which were marked with "-". 【0121】 [Table 1] [Explanation of symbols] 【0122】 1: Display system, 10: Display device, 11: Display surface, 12: Display panel, 13: Surface light source device, 20: Decorative laminate, 20a: First surface, 20b: Second surface, 21: First sheet, 22: Second sheet, 23: Bonding layer, 24: First base film, 25: Surface layer, 26: Second base film, 27: Design layer, 30: Decorative member, 35: Support part, 36: Adhesive layer, 37: Molded part, 251: Low reflectivity layer, 251a: Low refractive index layer, 251b: High refractive index layer, 252: Anti-glare layer, 252a: Binder resin, 252b: Fine particles, 253: Hard coat layer, DA: First direction, DB: Second direction, DC: Third direction
