[0016] Embodiments of the present disclosure will be described below. The same components will be given the same reference numerals, and their descriptions will not be repeated.

[0017] Embodiment 1. The decorative molded product 1 of Embodiment 1 will be described with reference to Figures 1 to 4. The decorative molded product 1 comprises a decorative sheet 2 and a molded body 20. The decorative molded product 1 may further comprise an adhesive layer 21. The decorative molded product 1 and the decorative sheet 2 can be applied to an infrared device 6 including an infrared device 27 (see Figure 3). The infrared device 6 is, for example, a display device 6d, an infrared camera, or an infrared transmitter. The display device 6d may be included in, for example, an automobile, a train, an elevator, a smartphone, or building materials such as a wall or a column. The decorative molded product 1 is, for example, a cover panel such as an interior or exterior panel of an automobile, or a front panel of a display device 6d.

[0018] Referring to Figure 1, when the light-emitting element 25 (see Figure 3) is off, a person viewing the decorated molded product 1 will see the design layer 12 of the decorative sheet 2. Referring to Figure 2, when the light-emitting element 25 is on, a person viewing the decorated molded product 1 will see the light passing through the decorative sheet 2 as object 7, in addition to the design layer 12. Object 7 may be, for example, letters, numbers, icons, symbols, patterns, or figures.

[0019] Referring to Figure 3, the decorative sheet 2 has a front surface 3 and a back surface 4 opposite to the front surface 3. A person viewing the decorative sheet 2 views it from the front surface 3. The decorative sheet 2 includes a design layer 12, a protective layer 13, and an infrared transmission filter 18. The decorative sheet 2 may further include a transparent film 11, a shielding layer 14, and at least one of a front-side color-tuning layer 15 or a back-side color-tuning layer 16. In this embodiment, at least one of the front-side color-tuning layer 15 or the back-side color-tuning layer 16 is both the front-side color-tuning layer 15 and the back-side color-tuning layer 16, and the decorative sheet 2 includes both the front-side color-tuning layer 15 and the back-side color-tuning layer 16.

[0020] Referring to Figure 3, the design layer 12 can transmit visible light, such as the light 26 emitted by the light emitter 25, and infrared light. The design layer 12 includes a region 12a that can transmit visible light and a region 12b that can transmit infrared light. The design layer 12 includes, for example, a binder and a pigment dispersed in the binder. The pigment is, for example, an interference pigment, an absorption pigment, or a metallic pigment, or a combination of two or more of these pigments. An interference pigment is a pigment that generates colored light through the interference of light reflected by the interference pigment. An absorption pigment is a pigment that generates colored light by absorbing light of a certain wavelength from the light incident on the absorption pigment. A metallic pigment is a pigment that exhibits metallic luster, and is, for example, a metal flake such as aluminum flake. A pattern such as a wood grain pattern or a tile pattern may be formed on the design layer 12. The design layer 12 may also be a colored layer. The design layer 12 may be a single layer or multiple layers.

[0021] The shielding layer 14 is positioned on the opposite side of the protective layer 13 from the design layer 12. The shielding layer 14 is positioned on the opposite side of the transparent film 11 from the design layer 12. The shielding layer 14 is positioned near the back surface 4 of the decorative sheet 2 from the design layer 12. The shielding layer 14 may have a back surface 4 of the decorative sheet 2. The shielding layer 14 is positioned between the design layer 12 and the molded body 20.

[0022] The shielding layer 14 is opaque to visible light, such as the light 26 emitted by the light emitter 25. Therefore, the shielding layer 14 hides objects on the back side 4 of the decorative sheet 2 (for example, the light emitter 25) from the viewer of the decorative sheet 2. In this specification, the fact that the shielding layer 14 is opaque to visible light means that the transmittance of the shielding layer 14 to visible light is 10% or less. The shielding layer 14 may be transparent to infrared light or opaque to infrared light. In this specification, the fact that the shielding layer 14 is transparent to infrared light means that the transmittance of the shielding layer 14 to infrared light is 45% or more at a wavelength of 940 nm. The fact that the shielding layer 14 is opaque to infrared light means that the transmittance of the shielding layer 14 to infrared light is 10% or less at a wavelength of 940 nm.

[0023] The shielding layer 14 includes, for example, a binder and a black pigment dispersed in the binder. The black pigment may be, for example, an infrared-transmitting ink mainly composed of bismuth sulfide powder, or a black ink containing carbon black that is opaque to visible and infrared light.

[0024] The shielding layer 14 is provided with an aperture 14a and an aperture 14b. Aperture 14a may define the visible image output area 6a of the display device 6d. Aperture 14a faces area 12a of the design layer 12. Aperture 14a may face the light emitter 25. Light 26 emitted by the light emitter 25 passes through aperture 14a and area 12a and exits from the front surface 3 of the decorative sheet 2. Aperture 14b may define an infrared light transmission area 6b. Aperture 14b faces area 12b. Aperture 14b may face the infrared device 27. Aperture 14b and area 12b are located on the optical path 28 of infrared light extending from the infrared device 27.

[0025] The infrared transmission filter 18 is, for example, an infrared transmission filter film. The infrared transmission filter 18 is positioned on the opposite side of the protective layer 13 from the design layer 12. The infrared transmission filter 18 faces the region 12b of the design layer 12 and the opening 14b of the shielding layer 14. The infrared transmission filter 18 may be positioned on the shielding layer 14, or it may close the opening 14b of the shielding layer 14.

[0026] The infrared transmission filter 18 is transparent to infrared light emitted or received by the infrared device 27. The transparency of the infrared transmission filter 18 to infrared light means that the transmittance of the shielding layer 14 to infrared light is 45% or more at a wavelength of 940 nm. Therefore, the infrared transmission filter 18 allows infrared light emitted or received by the infrared device 27 to pass through. The infrared transmission filter 18 is impermeable to visible light, such as the light 26 emitted by the light emitter 25. In this specification, the impermeability of the infrared transmission filter 18 to visible light means that the transmittance of the shielding layer 14 to visible light is 10% or less at a wavelength of 940 nm. Therefore, the infrared transmission filter 18 prevents malfunction of the infrared device 27 caused by visible light.

[0027] The protective layer 13 protects the design layer 12. The protective layer 13 may further protect the front-side color-tuning layer 15. The protective layer 13 constitutes the front surface 3 of the decorative sheet 2. The protective layer 13 can transmit visible light, such as the light 26 emitted by the light emitter 25, and infrared light emitted or received by the infrared device 27. The protective layer 13 is a hard coat layer having a higher hardness than the design layer 12. The protective layer 13 may have a hardness of HB or higher in a pencil hardness test (load 750g) in accordance with JIS (Japanese Industrial Standards) K 5600-5-4. Therefore, the protective layer 13 can prevent the design layer 12 from suffering mechanical damage. The protective layer 13 has a higher hardness than the layers of the decorative sheet 2 adjacent to the protective layer 13 (e.g., the front-side color-tuning layer 15). Therefore, the protective layer 13 can prevent the layers of the decorative sheet 2 adjacent to the protective layer 13 from suffering mechanical damage.

[0028] The protective layer 13 is formed of a resin such as an acrylic resin, polyurethane resin, silicone resin, or fluororesin. The thickness of the protective layer 13 is, for example, 1 μm or more and 50 μm or less.

[0029] The transparent film 11 may be a base film supporting the design layer 12 and the shielding layer 14. The transparent film 11 may be placed between the design layer 12 and the shielding layer 14. The design layer 12 is positioned near the front surface 3 of the decorative sheet 2 with respect to the transparent film 11. The shielding layer 14 is positioned near the back surface 4 of the decorative sheet 2 with respect to the transparent film 11. The transparent film 11 may contain a weather-resistant agent. Examples of weather-resistant agents include ultraviolet absorbers, light stabilizers, or ultraviolet blockers. This improves the weather resistance of the decorative sheet 2.

[0030] The transparent film 11 is transparent to visible light and infrared light, such as the light 26 emitted by the light-emitting body 25. The transparent film 11 is made of, for example, acrylic resin, polycarbonate resin, polyethylene terephthalate (PET) resin, polypropylene resin, or triacetylcellulose (TAC) resin. The transparent film 11 may be a single-layer film or a multi-layer film.

[0031] The front-side color-tuning layer 15 is positioned near the front surface 3 of the decorative sheet 2 relative to the design layer 12. The front-side color-tuning layer 15 is positioned on the side of the protective layer 13 relative to the design layer 12. The front-side color-tuning layer 15 is positioned between the design layer 12 and the protective layer 13. The front-side color-tuning layer 15 may cover the front surface of the design layer 12, or it may be formed on the front surface of the design layer 12. The front-side color-tuning layer 15 faces regions 12a and 12b of the design layer 12.

[0032] The front-side color-tuning layer 15 is transparent to visible light and infrared light, such as the light 26 emitted by the light-emitting element 25. The front-side color-tuning layer 15 includes, for example, a binder and a first absorbing pigment dispersed in the binder. The first absorbing pigment can absorb light of a first color component from the visible light traveling through the front-side color-tuning layer 15. The front-side color-tuning layer 15 colors the visible light traveling through it. The front-side color-tuning layer 15 can make the color of the visible light emitted from the front-side color-tuning layer 15 different from the color of the visible light incident on the front-side color-tuning layer 15. The front-side color-tuning layer 15 has a different color from the design layer 12. Therefore, the front-side color-tuning layer 15 colors the design of the design layer 12.

[0033] The back-side color-tuning layer 16 is positioned on the opposite side of the protective layer 13 from the design layer 12. The back-side color-tuning layer 16 is positioned near the back surface 4 of the decorative sheet 2 relative to the design layer 12. The back-side color-tuning layer is positioned between the design layer 12 and the molded body 20. The back-side color-tuning layer 16 may be positioned between the design layer 12 and the shielding layer 14. The back-side color-tuning layer 16 may cover the back surface of the design layer 12, or it may be formed on the back surface of the design layer 12. The back-side color-tuning layer 16 faces regions 12a and 12b of the design layer 12. The back-side color-tuning layer 16 is positioned between the design layer 12 and the infrared transmission filter 18.

[0034] The back-side color-tuning layer 16 is transparent to visible light and infrared light, such as the light 26 emitted by the light-emitting element 25. The back-side color-tuning layer 16 includes, for example, a binder and a second absorbing pigment dispersed in the binder. The back-side color-tuning layer 16 can transmit visible light (for example, the light 26 emitted by the light-emitting element 25) that travels through the back-side color-tuning layer 16. The second absorbing pigment can absorb the light of the second color component of the visible light that travels through the back-side color-tuning layer 16. Therefore, the back-side color-tuning layer 16 can reduce the light transmittance of the decorative sheet 2. The back-side color-tuning layer 16 may also color the visible light that travels through it. The back-side color-tuning layer 16 may also make the color of the visible light emitted from the back-side color-tuning layer 16 different from the color of the visible light incident on the back-side color-tuning layer 16.

[0035] If the decorative sheet 2 includes a front-side color-tuning layer 15, the front-side color-tuning layer 15 changes the color of the light 26 emitted by the light-emitting element 25. The light of the second color component absorbed by the second absorbing pigment of the back-side color-tuning layer 16 is different from the light of the first color component absorbed by the first absorbing pigment of the front-side color-tuning layer 15. The back-side color-tuning layer 16 may reduce the change in the visible light color caused by the front-side color-tuning layer 15, thereby mitigating the change in the light 26 to an undesirable color caused by the front-side color-tuning layer 15. The back-side color-tuning layer 16 may make the color of the light 26 passing through both the front-side color-tuning layer 15 and the back-side color-tuning layer 16 closer to achromatic than the color of the light 26 passing through only the front-side color-tuning layer 15. In this specification, "closer to achromatic" means that the distance from the white point is reduced in the xy chromaticity diagram (CIE 1931, 2° field of view). The white point is located at x=0.31271 and y=0.32902 in the xy chromaticity diagram (CIE 1931, 2° field of view), and at x=0.31382 and y=0.33100 in the xy chromaticity diagram (CIE 1964, 10° field of view).

[0036] The back-side color-tuning layer 16 may cancel out the coloring of the light 26 emitted by the light-emitting element 25 by the front-side color-tuning layer 15. The color of the back-side color-tuning layer 16 may be the complementary color of the color of the front-side color-tuning layer 15. The second color component absorbed by the second absorbing pigment of the back-side color-tuning layer 16 may be, for example, the complementary color of the first color component absorbed by the first absorbing pigment of the front-side color-tuning layer 15.

[0037] For example, referring to Figure 4, if the decorative sheet 2 includes a front-side color-tuning layer 15 but does not include a back-side color-tuning layer 16, the front-side color-tuning layer 15 changes the color of the light 26 emitted by the light emitter 25, indicated by the black circle in the xy chromaticity diagram (CIE 1931), to the color indicated by the white circle in the xy chromaticity diagram (CIE 1931). The back-side color-tuning layer 16 has the color indicated by the white triangle in the xy chromaticity diagram (CIE 1931). Therefore, if the decorative sheet 2 includes both the front-side color-tuning layer 15 and the back-side color-tuning layer 16, the color of the light 26 traveling through the decorative sheet 2 will be at the position of the white square in the xy chromaticity diagram (CIE 1931). In this way, the back-side color-tuning layer 16 matches the color of the light 26 emitted from the decorative sheet 2 to the color of the light 26 emitted by the light emitter 25, or brings it closer to the color of the light 26 emitted by the light emitter 25.

[0038] To make the design layer 12 easier to see, the light transmittance of the front-side color-tuning layer 15 may be higher than the light transmittance of the back-side color-tuning layer 16.

[0039] The light transmittance of the decorative sheet 2 to visible light, such as the light 26 emitted by the light-emitting element 25, is, for example, 10% or more. The light transmittance of the decorative sheet 2 to visible light may be 15% or more. This improves the visibility of object 7 (see Figure 2). The light transmittance of the decorative sheet 2 to visible light is, for example, 70% or less. The light transmittance of the decorative sheet 2 to visible light may be 50% or less. This prevents a viewer of the decorative sheet 2 from seeing objects on the back side 4 of the decorative sheet 2 (for example, the light-emitting element 25). When the decorative sheet 2 includes a shielding layer 14, the light transmittance of the decorative sheet 2 to visible light refers to the light transmittance of the portion of the decorative sheet 2 where the shielding layer 14 is not provided (the portion where the openings 14a and 14b are formed). The light transmittance of the decorative sheet 2 to visible light is, for example, 10% or more and 70% or less. The light transmittance of the decorative sheet 2 with respect to visible light may be between 15% and 50%.

[0040] Referring to Figure 3, the molded body 20 is positioned on the back surface 4 side of the decorative sheet 2. The molded body 20 is positioned on the opposite side of the protective layer 13 from the design layer 12. The molded body 20 faces regions 12a and 12b of the design layer 12. The molded body 20 faces openings 14a and 14b of the shielding layer 14. The molded body 20 supports the decorative sheet 2. The molded body 20 is positioned between the decorative sheet 2 and the light emitter 25. The molded body 20 is positioned between the decorative sheet 2 and the infrared device 27. The molded body 20 is transparent to visible light and infrared light, such as the light 26 emitted by the light emitter 25. The molded body 20 is formed from a resin such as a thermoplastic or thermosetting resin, or glass. The molded body 20 is shaped into a three-dimensional form, such as a flat plate or a curved plate.

[0041] The molded body 20 may be bonded to the back surface 4 of the decorative sheet 2 using an adhesive layer 21. The adhesive layer 21 is transparent to visible light and infrared light, such as the light 26 emitted by the light-emitting body 25. The adhesive layer 21 is formed of, for example, an optically transparent adhesive (OCA) or an optically transparent resin (OCR).

[0042] Referring to Figures 1 to 3, the display device 6d includes a visible image output area 6a and an infrared light transmission area 6b. The visible image output area 6a is the area where light emitted by the light emitter 25 is output. The infrared light transmission area 6b is the area through which infrared light is transmitted. The display device 6d includes a decorated molded product 1, a light emitter 25, and an infrared device 27.

[0043] The light-emitting element 25 faces the back surface 4 of the decorative sheet 2. The light-emitting element 25 is positioned on the side opposite to the decorative sheet 2 relative to the molded body 20. The light-emitting element 25 may face the opening 14a of the shielding layer 14 and the region 12a of the design layer 12.

[0044] The light-emitting element 25 can emit light 26. The light 26 is visible light. The light-emitting element 25, the aperture 14a of the shielding layer 14, and the region 12a of the design layer 12 are arranged in the optical path of the light 26 emitted by the light-emitting element 25.

[0045] The light-emitting element 25 may be an illumination light source such as a light-emitting diode (LED) light source. The illumination light source itself does not have the function of displaying letters, numbers, icons, symbols, patterns, or figures. When the light-emitting element 25 is an illumination light source, the shape of the opening 14a is the same as the shape of the object 7, such as letters, numbers, icons, symbols, patterns, or figures. When the illumination light source illuminates the decorative sheet 2, a person viewing the decorative molded product 1 will see the letters, numbers, icons, symbols, patterns, or figures as objects 7 through the opening 14a, along with the design layer 12.

[0046] The light-emitting element 25 may be a display device such as an LED display, an organic electroluminescent (EL) display, or a liquid crystal display (LCD). If the light-emitting element 25 is a display device, the shape of the aperture 14a may be different from that of the object 7, for example, it may be rectangular. The display device outputs image light such as characters, numbers, icons, symbols, patterns, or figures as light 26 toward the molded body 20 and the decorative sheet 2. A person viewing the decorated molded product 1 will see the characters, numbers, icons, symbols, patterns, or figures displayed by the display device, along with the design layer 12, as object 7 through the aperture 14a of the shielding layer 14 and the area 12a of the design layer 12.

[0047] The infrared device 27 may face the infrared transmission filter 18, the aperture 14b of the shielding layer 14, and the region 12b of the design layer 12. The infrared device 27, the infrared transmission filter 18, the aperture 14b of the shielding layer 14, and the region 12b of the design layer 12 are arranged on the infrared light path 28.

[0048] The infrared device 27 can emit or receive infrared light. The infrared device 27 may also be an infrared light-receiving element capable of receiving infrared light, such as an infrared imaging device or an infrared sensor. If the infrared device 27 is an infrared light-receiving element, the infrared light is received by the infrared device 27 after passing through the region 12b and aperture 14b of the design layer 12. The infrared device 27 may also be an infrared light-emitting element capable of emitting infrared light, such as an infrared LED. If the infrared device 27 is an infrared light-emitting element, the infrared light emitted from the infrared device 27 is emitted from the front surface 3 of the decorative sheet 2 after passing through the aperture 14b and the region 12b of the design layer 12.

[0049] Referring to Figure 5, an example of a manufacturing method for the decorative sheet 2 and the decorative molded product 1 of this embodiment will be described.

[0050] A protective layer 13 is formed (step S1). For example, a resin is applied to a base sheet (not shown) and the resin is cured. In this way, the protective layer 13 is formed.

[0051] A front-side color-tuning layer 15 is formed on the protective layer 13 (step S2). For example, an ink containing a binder resin and a first absorbent pigment is printed on the protective layer 13. The ink is dried. In this way, the front-side color-tuning layer 15 is formed.

[0052] A design layer 12 is formed on the front-side color-tuning layer 15 (step S3). For example, an ink containing a binder resin and a pigment is printed on the front-side color-tuning layer 15. The ink is dried. In this way, the design layer 12 is formed.

[0053] A back-side color-tuning layer 16 is formed on the design layer 12 (step S4). For example, an ink containing a binder resin and a second absorbent pigment is printed on the design layer 12. The ink is dried. In this way, the back-side color-tuning layer 16 is formed.

[0054] A laminate comprising a base sheet (not shown), a protective layer 13, a front-side color-tuning layer 15, a design layer 12, and a back-side color-tuning layer 16 is laminated onto a transparent film 11 (step S5).

[0055] A shielding layer 14 is formed on the transparent film 11 (step S6). For example, black ink containing a binder resin and black pigment is printed on the back surface of the transparent film 11. The black ink is dried. In this way, the shielding layer 14 is formed. The openings 14a and 14b of the shielding layer 14 are formed, for example, by not printing black ink on those areas.

[0056] An infrared-transmitting filter 18 is provided on the shielding layer 14 (step S7). For example, an ink containing a binder resin and an organic pigment is printed on the back surface of the shielding layer 14. The organic pigment absorbs visible light and transmits infrared light. The ink is dried. In this way, the infrared-transmitting filter 18 is formed. The decorative sheet 2 of this embodiment is obtained by steps S1-S7. In other words, the method for manufacturing the decorative sheet 2 of this embodiment includes steps S1-S7.

[0057] A molded body 20 is formed on the back surface 4 of the decorative sheet 2 (step S8). Specifically, an adhesive layer 21 is formed on the back surface 4 of the decorative sheet 2 (for example, the shielding layer 14, the transparent film 11, and the infrared transmission filter 18) to form a transfer sheet. The transfer sheet includes a transfer layer and a base sheet. The transfer layer includes a protective layer 13, a front-side color-tuning layer 15, a design layer 12, a back-side color-tuning layer 16, a transparent film 11, a shielding layer 14, and an adhesive layer 21.

[0058] Next, a transfer sheet is placed in the cavity of a mold (not shown). Resin is injected into the cavity of the mold. The injected resin is cured to form a molded body 20. The molded body 20 is bonded to the decorative sheet 2 using an adhesive layer 21. The molded body 20 is removed from the mold. When the molded body 20 is removed from the mold, the base sheet is peeled off from the protective layer 13. In this way, the transfer layer is transferred to the molded body 20, and the decorated molded product 1 of this embodiment is obtained.

[0059] The operation of the decorative sheet 2 and the decorative molded product 1 in this embodiment will be explained. An infrared device 6 (e.g., display device 6d) including an infrared device 27 and an infrared transmission filter 18 is used for monitoring drivers or passengers in automobiles, trains, or elevators, or for communication with other communication devices. Because the infrared transmission filter 18 is black, the aesthetic appeal of the infrared device 6 is reduced. Also, if a person viewing the infrared device 6 sees the infrared transmission filter 18, they may perceive that they are being monitored by the infrared device 6 and experience feelings of aversion or stress.

[0060] In the decorative sheet 2 of this embodiment, the design layer 12 includes a region 12a that can transmit visible light and a region 12b that can transmit infrared light. The infrared transmission filter 18 is positioned on the opposite side of the design layer 12 from the protective layer 13 and faces region 12b. Therefore, the decorative sheet 2 and the decorative molded product 1 can decorate the infrared light transmission region 6b of the infrared device 6, preventing a viewer of the infrared device 6 from seeing the infrared transmission filter 18. The decorative sheet 2 and the decorative molded product 1 can improve the aesthetic appearance of the infrared device 6. The decorative sheet 2 and the decorative molded product 1 can prevent a viewer of the infrared device 6 from feeling aversion or stress.

[0061] (modified version) Referring to Figure 6, in the first modified example of this embodiment, the decorative sheet 2 includes a front-side color-tuning layer 15 but does not include a back-side color-tuning layer 16. That is, at least one of the front-side color-tuning layer 15 or the back-side color-tuning layer 16 is the front-side color-tuning layer 15. For example, if the decorative sheet 2 has sufficient light transmittance, due to the design layer 12 and the front-side color-tuning layer 15, to prevent a viewer of the decorative sheet 2 from seeing objects on the back side 4 of the decorative sheet 2 (e.g., a light-emitting element 25), then the back-side color-tuning layer 16 may be omitted.

[0062] Referring to Figure 7, in the second modified example of this embodiment, the decorative sheet 2 includes a back-side color-tuning layer 16 but does not include a front-side color-tuning layer 15. That is, at least one of the front-side color-tuning layer 15 or the back-side color-tuning layer 16 is the back-side color-tuning layer 16. The front-side color-tuning layer 15 can be omitted if it is not necessary to color the ambient light reflected by the design layer 12. The back-side color-tuning layer 16 reduces the light transmittance of the decorative sheet 2, preventing a viewer of the decorative sheet 2 from seeing objects on the back side 4 of the decorative sheet 2 (for example, a light-emitting element 25).

[0063] Referring to Figure 8, in a third modified example of this embodiment, the transparent film 11 may be placed between the design layer 12 and the protective layer 13. The transparent film 11 may also be placed between the front-side color-tuning layer 15 and the protective layer 13.

[0064] Referring to Figure 9, an example of a method for manufacturing the decorated molded product 1 of a third modified example of this embodiment will be described.

[0065] A protective layer 13 is formed (step S1). For example, a resin is applied to the front surface of the transparent film 11 and the resin is cured. In this way, the protective layer 13 is formed.

[0066] A front-side color-tuning layer 15 is formed on the transparent film 11 (step S2). For example, an ink containing a binder resin and a first absorbent pigment is printed on the back surface of the transparent film 11. The ink is dried. In this way, the front-side color-tuning layer 15 is formed.

[0067] A design layer 12 is formed on the front-side color-tuning layer 15 (step S3). A back-side color-tuning layer 16 is formed on the design layer 12 (step S4). Steps S3 and S4 are as previously described.

[0068] A shielding layer 14 is formed (step S6). For example, a black ink containing a binder resin and a black pigment is printed onto the back-side color matching layer 16. The black ink is dried. In this way, the shielding layer 14 is formed. The openings 14a of the shielding layer 14 are formed, for example, by not printing black ink on those areas.

[0069] An infrared transmission filter 18 is provided on the back surface of the shielding layer 14 (step S7). Step S7 is as previously described. Thus, by steps S1-S4, S6, and S7, the decorative sheet 2 of the third modified example of this embodiment is obtained.

[0070] A molded body 20 is formed on the back surface 4 of the decorative sheet 2 (step S8). The molded body 20 may be formed on the back surface 4 of the decorative sheet 2 by insert molding or in-mold molding. The molded body 20 may be bonded to the back surface 4 of the decorative sheet 2 using an adhesive layer 21. In this way, a decorative molded product 1 of the third modified example of this embodiment is obtained.

[0071] Referring to Figure 10, in the fourth modification of this embodiment, the opening 14a may be composed of a plurality of holes 14h. In a plan view of the front surface 3 of the decorative sheet 2, the shape of each of the plurality of holes 14h is not particularly limited, but may be circular, elliptical, triangular, square, or hexagonal. The plurality of holes 14h are formed by laser processing the shielding layer 14.

[0072] Each of the multiple holes 14h is of a size that is difficult for a viewer of the decorative sheet 2 to see. In a plan view of the front surface 3 of the decorative sheet 2, the area of ​​each of the multiple holes 14h is, for example, 1.8 mm. 2 The following applies: The area of ​​each of the multiple holes 14h is 1.0 mm². 2 The following may also apply: The area of ​​each of the multiple pores 14h is, for example, 3840 μm². 2 That concludes the explanation. The area of ​​each of the multiple holes 14h is 0.018 mm². 2 The area of ​​each of the multiple pores 14h is, for example, 3840 μm². 2 1.8mm 2 The following applies: The area of ​​each of the multiple holes 14h is 0.018 mm². 2 1.0mm or more 2 The following is also acceptable.

[0073] The aperture ratio of the multiple holes 14h is, for example, 10% or more. The aperture ratio of the multiple holes 14h is, for example, 20% or less. The aperture ratio of the multiple holes 14h is, for example, 10% or more and 20% or less. In this specification, the aperture ratio of the multiple holes 14h is the ratio of the area of ​​the multiple holes 14h to the area of ​​the shielding layer 14 in a plan view of the front surface 3 of the decorative sheet 2. Because the aperture ratio of the multiple holes 14h is 20% or less, the shielding layer 14 can prevent a person viewing the decorative sheet 2 from seeing an object on the back surface 4 side of the decorative sheet 2 (for example, a light-emitting object 25). Because the aperture ratio of the multiple holes 14h is 10% or more, the visibility of the object 7 (see Figure 2) seen through the multiple holes 14h is improved.

[0074] In one example of the fourth modification, the light-emitting element 25 is a display device that outputs image light such as characters, numbers, icons, symbols, patterns, or figures. When the light-emitting element 25 is a display device, the multiple holes 14h are arranged two-dimensionally and periodically and can function as multiple pixels. A person viewing the decorated molded product 1 will see the characters, numbers, icons, symbols, patterns, or figures displayed by the display device as objects 7 through the multiple holes 14h, along with the design layer 12.

[0075] In another example of the fourth modification, the light-emitting element 25 is an illumination light source such as an LED light source. The illumination light source itself does not have the function of displaying letters, numbers, icons, symbols, patterns, or figures. When the light-emitting element 25 is an illumination light source, the multiple holes 14h are arranged in the shape of letters, numbers, icons, symbols, patterns, or figures. The multiple holes 14h can function as multiple pixels of letters, numbers, icons, symbols, patterns, or figures. By the illumination light source illuminating the decorative sheet 2, a person viewing the decorative molded product 1 can see the letters, numbers, icons, symbols, patterns, or figures as objects 7 through the multiple holes 14h, along with the design layer 12.

[0076] Referring to Figure 11, the infrared device 6 in the fifth modified example of this embodiment is not a display device 6d (see Figure 3), but rather, for example, an infrared camera or an infrared transmitter. Specifically, the infrared device 6 does not have a light-emitting element 25 (see Figure 3) and does not have a visible image output area 6a (see Figure 3). The shielding layer 14 does not have an opening 14a (see Figure 3). The design layer 12 does not include an area 12a (see Figure 3) that can transmit visible light.

[0077] The effects of the decorative sheet 2, decorative molded product 1, infrared device 6, and display device 6d of this embodiment will be explained.

[0078] The decorative sheet 2 of this embodiment comprises a design layer 12, a protective layer 13, and an infrared transmission filter 18. The design layer 12 contains a pigment and includes a first region (region 12b) that can transmit infrared light. The infrared transmission filter 18 is opaque to visible light and transparent to infrared light, is positioned on the opposite side of the design layer 12 from the protective layer 13, and faces the first region.

[0079] Therefore, the decorative sheet 2 can decorate the infrared light transmission area 6b of the infrared device 6, and can prevent viewers of the infrared device 6 from seeing the infrared transmission filter 18. The decorative sheet 2 can improve the aesthetic appearance of the infrared device 6. The decorative sheet 2 can prevent viewers of the infrared device 6 from feeling aversion or stress.

[0080] In the decorative sheet 2 of this embodiment, the design layer 12 further includes a second region (region 12a) that can transmit visible light.

[0081] Therefore, the decorative sheet 2 can decorate the visible image output area 6a and the infrared light transmission area 6b of the infrared device 6 (for example, the display device 6d), and can prevent a person viewing the infrared device 6 from seeing the infrared transmission filter 18. The decorative sheet 2 can improve the aesthetic appearance of the infrared device 6. The decorative sheet 2 can prevent a person viewing the infrared device 6 from feeling aversion or stress.

[0082] The decorative sheet 2 of this embodiment further comprises a shielding layer 14. The shielding layer 14 is positioned on the opposite side of the protective layer 13 from the design layer 12. The shielding layer 14 is provided with a first opening (opening 14b) facing a first region (region 12b) and a second opening (opening 14a) facing a second region (region 12a). The infrared transmission filter 18 closes the first opening.

[0083] The shielding layer 14 can prevent a viewer of the decorative sheet 2 from seeing objects on the back side 4 of the decorative sheet 2. The decorative sheet 2 can improve the aesthetic appearance of the infrared device 6. Furthermore, since the shielding layer 14 has a first opening (opening 14b), even if the shielding layer 14 is opaque to infrared light, the decorative sheet 2 can transmit infrared light. The decorative sheet 2 does not interfere with the operation of the infrared device 27.

[0084] The decorative sheet 2 of this embodiment further comprises at least one of a front-side color-tuning layer 15 or a back-side color-tuning layer 16. The front-side color-tuning layer 15 is located between the protective layer 13 and the design layer 12, faces a first region (region 12b) and a second region (region 12a), contains a first absorbing pigment, and has a different color from the design layer 12. The back-side color-tuning layer 16 is located between the design layer 12 and the infrared transmission filter 18, faces a first region and a second region, and contains a second absorbing pigment.

[0085] The front-side color-tuning layer 15 may provide the viewer of the decorative sheet 2 with an appearance that has a different color from the design layer 12. The design of the decorative sheet 2 is improved. The back-side color-tuning layer 16 may reduce the light transmittance of the decorative sheet 2. The decorative sheet 2 including the back-side color-tuning layer 16 may prevent the viewer of the decorative sheet 2 from seeing objects on the back side 4 of the decorative sheet 2. The design of the decorative sheet 2 is improved.

[0086] In the decorative sheet 2 of this embodiment, at least one of the front-side color-tuning layer 15 or the back-side color-tuning layer 16 is both the front-side color-tuning layer 15 and the back-side color-tuning layer 16. The color of the back-side color-tuning layer 16 is the complementary color of the color of the front-side color-tuning layer 15.

[0087] The back-side color-tuning layer 16 can cancel out the coloring of the light 26 emitted by the light-emitting element 25 by the front-side color-tuning layer 15. Therefore, the decorative sheet 2 can suppress the color change of the light 26 emitted by the light-emitting element 25.

[0088] The decorative sheet 2 of this embodiment further comprises a shielding layer 14. The shielding layer 14 is positioned on the opposite side of the protective layer 13 from the design layer 12. The shielding layer 14 is provided with an opening 14b facing the first region (region 12b). The infrared transmission filter 18 closes the opening 14b.

[0089] The shielding layer 14 can prevent a viewer of the decorative sheet 2 from seeing objects on the back side 4 of the decorative sheet 2. The decorative sheet 2 can improve the aesthetic appearance of the infrared device 6. Furthermore, since the shielding layer 14 has an opening 14b, even if the shielding layer 14 is opaque to infrared light, the decorative sheet 2 can transmit infrared light. The decorative sheet 2 does not interfere with the operation of the infrared device 27.

[0090] The decorated molded product 1 of this embodiment comprises a decorative sheet 2 and a molded body 20 that supports the decorative sheet 2. The molded body 20 is transparent to infrared light, is positioned on the opposite side of the protective layer 13 from the design layer 12, and faces the first region (region 12b).

[0091] Therefore, the decorative molded product 1 can decorate the infrared light transmission region 6b of the infrared device 6, and can prevent a person viewing the infrared device 6 from seeing the infrared transmission filter 18. The decorative molded product 1 can improve the aesthetic design of the infrared device 6. The decorative molded product 1 can prevent a person viewing the infrared device 6 from feeling aversion or stress.

[0092] The infrared device 6 of this embodiment comprises a decorated molded product 1 and an infrared device 27 capable of emitting or receiving infrared light. The first region (region 12b), the infrared transmission filter 18, and the infrared device 27 are arranged on the infrared light optical path 28.

[0093] Therefore, the decorative molded product 1 can decorate the infrared light transmission region 6b of the infrared device 6, and can prevent a person viewing the infrared device 6 from seeing the infrared transmission filter 18. The decorative molded product 1 can improve the aesthetic design of the infrared device 6. The decorative molded product 1 can prevent a person viewing the infrared device 6 from feeling aversion or stress.

[0094] The display device 6d of this embodiment comprises a decorative sheet 2, a molded body 20 supporting the decorative sheet 2, a light-emitting body 25 capable of emitting visible light, and an infrared device 27 capable of emitting or receiving infrared light. The molded body 20 is transparent to visible light and infrared light, is positioned on the opposite side of the protective layer 13 from the design layer 12, and faces the first region (region 12b) and the second region (region 12a). The first region, the infrared transmission filter 18, and the infrared device 27 are arranged on the optical path 28 for infrared light. The second region and the light-emitting body 25 are arranged on the optical path for visible light.

[0095] Therefore, the decorative sheet 2 decorates the visible image output area 6a and the infrared light transmission area 6b of the display device 6d, preventing the viewer of the display device 6d from seeing the infrared transmission filter 18. The design of the display device 6d, including the infrared device 27, is improved. The display device 6d may prevent the viewer of the display device 6d from feeling aversion or stress.

[0096] Embodiment 2. Referring to Figure 12, the decorative sheet 2, decorative molded product 1, and infrared device 6 (for example, display device 6d) of Embodiment 2 will be described. The decorative sheet 2, decorative molded product 1, and infrared device 6 of this embodiment are configured similarly to the decorative sheet 2, decorative molded product 1, and infrared device 6 of Embodiment 1, but differ from the decorative sheet 2, decorative molded product 1, and infrared device 6 of Embodiment 1 mainly in the following points.

[0097] In this embodiment, the shielding layer 14 is opaque to visible light but transparent to infrared light. The shielding layer 14 has an opening 14a, but no opening 14b.

[0098] The infrared transmission filter 18 is the portion of the shielding layer 14 facing region 12b. The portion of the shielding layer 14 facing region 12b is located on the optical path 28 of infrared light extending from the infrared device 27. If the infrared device 27 is an infrared light receiving element, infrared light is received by the infrared device 27 after passing through region 12b of the design layer 12 and the portion of the shielding layer 14 facing region 12b. If the infrared device 27 is an infrared light-emitting element, infrared light emitted from the infrared device 27 is emitted from the front surface 3 of the decorative sheet 2 after passing through the portion of the shielding layer 14 facing region 12b of the design layer 12 and region 12b of the design layer 12.

[0099] Referring to Figure 13, the modified infrared device 6 of this embodiment is not a display device 6d (see Figure 3), but rather, for example, an infrared camera or an infrared transmitter. Specifically, the infrared device 6 does not have a light emitter 25 (see Figure 12) and does not have a visible image output area 6a (see Figure 12). The shielding layer 14 does not have an opening 14a (see Figure 12). The design layer 12 does not include an area 12a (see Figure 12) that can transmit visible light. In the modified embodiment, the shielding layer 14 is transparent to infrared light, but may be opaque or transparent to visible light.

[0100] The decorative sheet 2, decorative molded product 1, and infrared device 6 of this embodiment provide the same effects as those of the decorative sheet 2, decorative molded product 1, and infrared device 6 of Embodiment 1.

[0101] The decorative sheet 2 of this embodiment further comprises a shielding layer 14. The shielding layer 14 is positioned on the opposite side of the protective layer 13 from the design layer 12 and is transparent to infrared light. The shielding layer 14 is provided with an opening 14a facing the second region (region 12a). The infrared transmission filter 18 is the portion of the shielding layer 14 facing the first region (region 12b).

[0102] Therefore, the decorative sheet 2 can decorate the visible image output area 6a and the infrared light transmission area 6b of the infrared device 6 (e.g., display device 6d), and can prevent viewers of the infrared device 6 from seeing the infrared transmission filter 18. The decorative sheet 2 can improve the aesthetic appearance of the infrared device 6. The decorative sheet 2 can prevent viewers of the infrared device 6 from feeling aversion or stress. Since there is no need to provide an infrared transmission filter 18 separately from the shielding layer 14, the cost and thickness of the decorative sheet 2 are reduced.

[0103] The decorative sheet 2 of this embodiment further comprises a shielding layer 14. The shielding layer 14 is positioned on the opposite side of the protective layer 13 from the design layer 12 and is transparent to infrared light. The infrared transmission filter 18 is the portion of the shielding layer 14 that faces the first region (region 12b).

[0104] Therefore, the decorative sheet 2 can decorate the infrared light transmission region 6b of the infrared device 6, and can prevent viewers of the infrared device 6 from seeing the infrared transmission filter 18. The decorative sheet 2 can improve the aesthetic appearance of the infrared device 6. The decorative sheet 2 can prevent viewers of the infrared device 6 from feeling aversion or stress. Since there is no need to provide an infrared transmission filter 18 separately from the shielding layer 14, the cost and thickness of the decorative sheet 2 are reduced.

[0105] The decorated molded product 1 of this embodiment comprises a decorative sheet 2 of this embodiment and a molded body 20 that supports the decorative sheet 2. The molded body 20 is transparent to infrared light, is positioned on the opposite side of the protective layer 13 from the design layer 12, and faces the first region (region 12b).

[0106] Therefore, the decorative molded product 1 can decorate the infrared light transmission region 6b of the infrared device 6, and can prevent viewers of the infrared device 6 from seeing the infrared transmission filter 18. The decorative molded product 1 can improve the aesthetic appearance of the infrared device 6. The decorative molded product 1 can prevent viewers of the infrared device 6 from feeling aversion or stress. Since there is no need to provide an infrared transmission filter 18 separately from the shielding layer 14, the cost and thickness of the decorative molded product 1 are reduced.

[0107] The infrared device 6 of this embodiment comprises the decorated molded product 1 of this embodiment and an infrared device 27 capable of emitting or receiving infrared light. The first region (region 12b), the infrared transmission filter 18, and the infrared device 27 are arranged on the infrared light optical path 28.

[0108] Therefore, the decorative molded product 1 can decorate the infrared light transmission region 6b of the infrared device 6, and can prevent viewers of the infrared device 6 from seeing the infrared transmission filter 18. The decorative molded product 1 can improve the aesthetic appearance of the infrared device 6. The decorative molded product 1 can prevent viewers of the infrared device 6 from feeling aversion or stress. Since there is no need to provide an infrared transmission filter 18 separately from the shielding layer 14, the cost and thickness of the decorative molded product 1 are reduced.

[0109] The display device 6d of this embodiment comprises a decorative sheet 2 of this embodiment, a molded body 20 supporting the decorative sheet 2, a light-emitting body 25 capable of emitting visible light, and an infrared device 27 capable of emitting or receiving infrared light. The molded body 20 is transparent to visible light and infrared light, is positioned on the opposite side of the protective layer 13 from the design layer 12, and faces the first region (region 12b) and the second region (region 12a). The first region, the infrared transmission filter 18, and the infrared device 27 are arranged on the optical path 28 for infrared light. The second region and the light-emitting body 25 are arranged on the optical path for visible light.

[0110] Therefore, the decorative sheet 2 decorates the visible image output area 6a and the infrared light transmission area 6b of the display device 6d, preventing viewers of the display device 6d from seeing the infrared transmission filter 18. The design of the display device 6d, including the infrared device 27, is improved. The display device 6d can prevent viewers of the display device 6d from feeling aversion or stress. Since there is no need to provide an infrared transmission filter 18 separately from the shielding layer 14, the cost and thickness of the display device 6d are reduced.

[0111] Embodiment 3. Referring to Figure 14, the decorative sheet 2, decorative molded product 1, and infrared device 6 (for example, display device 6d) of Embodiment 3 will be described. The decorative sheet 2, decorative molded product 1, and infrared device 6 of this embodiment are configured similarly to the decorative sheet 2, decorative molded product 1, and infrared device 6 of Embodiment 1, but differ from the decorative sheet 2, decorative molded product 1, and infrared device 6 of Embodiment 1 mainly in the following points.

[0112] In this embodiment, the decorative sheet 2 does not include the infrared transmission filter 18. The infrared device 6 in this embodiment includes the infrared transmission filter 18. The infrared transmission filter 18 is, for example, an infrared transmission filter plate. The infrared transmission filter 18 is positioned between the decorative molded product 1 and the infrared device 27. The infrared transmission filter 18 is positioned between the decorative sheet 2 and the infrared device 27. More specifically, the infrared transmission filter 18 is positioned between the molded body 20 and the infrared device 27. The infrared device 27, the infrared transmission filter 18, the opening 14b of the shielding layer 14, and the region 12b of the design layer 12 are positioned on the infrared light path 28.

[0113] The decorative sheet 2 of this embodiment may further include at least one of the front-side color-tuning layer 15 or the back-side color-tuning layer 16, similar to the decorative sheet 2 of Embodiment 1. The front-side color-tuning layer 15 is located between the protective layer 13 and the design layer 12, facing region 12a and region 12b, contains a first absorbing pigment, and has a different color from the design layer 12. The back-side color-tuning layer 16 is located between the design layer 12 and the molded body 20, facing region 12a and region 12b, and contains a second absorbing pigment.
