Description

The present invention relates to a decorative sheet, a cover panel and a display device having a pattern formed of interference pigments.

For example, Patent Document 1 (Japanese Patent No. 6839319) discloses a technique of using interference pigments (also referred to as optical interference pigments) in a decorative sheet that is used for simultaneous molding and decoration. As described in Patent Literature 1, various colors can be provided by using interference pigments that produce different colors due to interference light obtained by being reflected by the pigments. By mixing interference pigments with different colors, it is possible to express different colors. For example, purple can be expressed by mixing an interference pigment that develops red and an interference pigment that develops blue.

Japanese Patent No. 6839319

As described in Patent Document 1, when a decorative sheet is used to express different images depending on reflected light and transmitted light, interference pigments that do not easily color transmitted light may be more advantageous than absorption pigments.
However, since the interference pigment expresses color using color development due to interference of reflected light, the color tone may change depending on the viewing angle of the interference pigment. In addition, interference pigments that use interference light tend to give the viewer a pearl-like luster compared to absorption pigments that develop colors by absorbing light of a specific wavelength. Although it is conceivable to positively utilize such color development peculiar to interference pigments, there are cases where the difference in appearance from absorption pigments that have been generally used is not desirable.

SUMMARY OF THE INVENTION An object of the present invention is to improve versatility by suppressing the color development peculiar to interference pigments in a pattern formed using an interference pigment on a decorative sheet. Another object of the present invention is to provide a cover panel and a display device to which such a decorative sheet is applied.

The front side toning layer contains a front side absorption pigment uniformly dispersed throughout the front side toning layer, and the front side absorption pigment reduces spectral components in a predetermined range of wavelengths from light transmitted through the front side toning layer.
In the decorative sheet thus constructed, the absorption pigment in the front-side toning layer suppresses the lustrous appearance of the design by the interference pigment, such as pearls. Further, the impression that the color tone of the pattern given to the viewer is changed depending on the angle at which the pattern is viewed can be alleviated by setting a predetermined range of spectral components to be reduced by the front side toning layer.

<First embodiment>
(1) Overall Configuration FIGS. 1A and 1B show the cover panel 10 according to the first embodiment viewed from the front side. FIG. 2 schematically shows the cross-sectional shape of the cover panel 10. As shown in FIG. A person viewing the cover panel 10 visually recognizes the cover panel 10 from the side of the surface 10 a of the cover panel 10 . As shown in FIG. 2, the light source 2 is arranged on the back surface 10b side of the cover panel 10. As shown in FIG. A display device 50 is configured by the cover panel 10 and the light source 2 .
FIG. 1A shows how the cover panel 10 appears when the light source 2 is not lit and there is only incident light IL1 from the surface 10a of the cover panel 10. FIG. FIG. 1B shows how the cover panel 10 looks when the light source 2 is turned on and there is incident light IL2 from the back surface 10b side of the cover panel 10. FIG. As can be seen by comparing FIG. 1A and FIG. 1B, when the light source 2 is not turned on, a person looking at the cover panel 10 can see only the wood grain pattern 100 on the surface 10a of the cover panel 10. . When the light source 2 is turned on, the icon 110 is displayed in the wood grain pattern 100.例文帳に追加Here, a case where the design 100 is wood grain will be described, but the design 100 is not limited to wood grain.

The cover panel 10 includes a hard coat layer 11, a front side toning layer 12, a pattern layer 13, a back side toning layer 14, a shielding layer 15, an adhesive layer 16 and a molding member 17. - 特許庁
In order to enable display of the icon 110, the hard coat layer 11, the front side toning layer 12, the pattern layer 13, the back side toning layer 14, the adhesive layer 16, and the molding member 17 are incident from the back side 10b of the cover panel 10. It is configured to allow the incident light IL2 to pass therethrough. In the cover panel 10 shown in FIG. 2, the shape of the icon 110 is determined by the shielding layer 15 . The shape of the portion where the shielding layer 15 is not formed becomes the shape of the icon 110 . For example, the “A/C” icon 110 indicating the operating state of the air conditioner can be displayed by openings in the shape of “A”, “/” and “C” formed in the shielding layer 15 .

The wood grain pattern 100 is formed in the pattern layer 13. - 特許庁The pattern layer 13 contains interference pigments 21 for forming the pattern 100 . When the incident light IL1 is reflected by the interference pigment 21, the interference of the reflected light RL1 causes color development. Part of the incident light IL1 that has entered the pattern layer 13 is reflected and emitted to the surface 10a side of the cover panel 10 . This reflected light RL1 is visually recognized by a person who views the cover panel 10, and makes the pattern 100 of the wood grain pattern appear. As described above, in the pattern layer 13, the pattern 100 is formed of the interference pigments 21 that develop color by interference of the reflected light of the light incident from the surface 13a of the pattern layer 13. As shown in FIG. The pattern layer 13 in which the pattern 100 is formed by the interference pigment 21 as described above can transmit light from the rear surface 13b of the pattern layer 13 to the front surface 13a.
The hard coat layer 11 is made of a material that can transmit the incident lights IL1 and IL2 from both the front surface 10a and the back surface 10b of the cover panel 10. As shown in FIG. The hard coat layer 11 is made of, for example, a transparent high-hardness resin. The hard coat layer 11 also transmits the reflected light RL<b>1 reflected by the pattern layer 13 .

The front side toning layer 12 covers the surface 13 a of the pattern layer 13 . The front-side toning layer 12 can transmit incident light IL1 incident on the surface 13a of the pattern layer 13, reflected light RL1 emitted from the pattern layer 13 to the outside, and incident light IL2 from the rear surface 10b of the cover panel 10. The front side toning layer 12 contains a front absorption pigment 22 uniformly dispersed throughout the front side toning layer 12 . The front side toning layer 12 uses the front side absorption pigment 22 to reduce spectral components of wavelengths within a predetermined range from light transmitted through the front side toning layer 12 . When passing through the front-side absorption pigment 22, the incident light IL1 from the front surface 10a side of the cover panel 10, the incident light IL2 from the rear surface 10b side, and the reflected light RL1 are reduced in spectral components in a predetermined range of wavelengths. . In other words, the front side absorption pigment 22 is an absorption pigment having a light absorption property that reduces spectral components in a predetermined range of wavelengths from light transmitted through the front side toning layer 12 . For example, a yellow front-side absorbing pigment 22 reduces spectral components having a predetermined range of wavelengths other than the wavelengths of yellow spectral components.

The back side toning layer 14 covers the back side 13b of the pattern layer 13. - 特許庁The back-side toning layer 14 can transmit the incident light IL1 incident on the front surface 13a of the pattern layer 13 and the incident light IL2 from the back surface 10b of the cover panel 10. FIG. Part of the incident light IL1 incident on the surface 13a of the pattern layer 13 is reflected by the interference pigments 21, but the light that is not reflected by the interference pigments 21 in the incident light IL1 is transmitted through the back side toning layer . The backside toning layer 14 includes a backside absorbing pigment 23 uniformly dispersed throughout the backside toning layer 14 . The back-side absorption pigment 23 has a light absorption characteristic that makes the light passing through the two layers of the back-side toning layer 14 and the front-side toning layer 12 more achromatic than the light passing through only the front-side toning layer 12 . It is an absorption pigment with
Here, "approaching an achromatic color" means that the distance from the white point decreases in the xy chromaticity diagram of CIE1931. In other words, "approaching an achromatic color" means that if the chromaticity and saturation can be changed so as to approach the white point of the xy chromaticity diagram, a decrease in lightness is allowed. Here, the white point of the XY chromaticity diagram is considered based on D65. The white point is X=0.31382, y=0.33100 in the CIE1964 10° colorimetric standard observer and x=0.31271, y=0.32902 in the chromaticity coordinates of the CIE1931 color space. .

The shielding layer 15 is a layer that blocks light transmitted through a predetermined portion. The shielding layer 15 is arranged closer to the back surface 10 b of the cover panel 10 than the pattern layer 13 and further than the back toning layer 14 . A portion of the shielding layer 15 other than the predetermined portion is the opening 15a. The opening 15a is a portion that allows light to pass through. An icon 110 is displayed through the opening 15a.

The adhesive layer 16 is provided on the back surface of the shielding layer 15 and transmits visible light. An adhesive layer 16 adheres the shielding layer 15 and the molded member 17 . The molding member 17 is composed of a member capable of transmitting light. Materials that can transmit light include, for example, glass and light-transmitting resin. Light-transmitting resins include, for example, light-transmitting thermoplastic resins and light-transmitting thermosetting resins. The molded member 17 is a member processed into a desired shape. A molding member 17 , shown in FIGS. 1A, 1B and 2, forms the shape of the cover panel 10 . If the cover panel 10 is plate-shaped, for example, the molding member 17 is plate-shaped. The molded member 17 supports the hard coat layer 11 , front side toning layer 12 , pattern layer 13 , back side toning layer 14 , shielding layer 15 and adhesive layer 16 . Here, a case where the shape of the cover panel 10 is planar will be described, but the shape of the cover panel 10 may be three-dimensional. The cover panel 10 may have, for example, a curved cross-sectional shape.

The cover panel 10 is manufactured, for example, by transferring it to the molding member 17 simultaneously with the injection molding of the molding member 17 . Alternatively, the cover panel 10 may be manufactured by adhering the decorative sheet 8 to the molding member 17 simultaneously with the injection molding of the molding member 17, like the cover panel 10 shown in FIG. Alternatively, the molding member 17 may be made of glass. The cover panel 10 is manufactured by attaching the decorative sheet 8 to the molding member 17 made of glass with an adhesive after molding the molding member 17 . For example, when the molding member 17 is made of resin, it may be formed by injection molding, extrusion molding, blow molding, vacuum molding, air pressure molding, compression molding, or may be machined.
The decorative sheet 8 includes a hard coat layer 11 , a base film 18 , a front side toning layer 12 , a pattern layer 13 , a back side toning layer 14 , a shielding layer 15 and an adhesive layer 16 . The base film 18 is a film that transmits visible light. Here, the case where the base film 18 is transparent will be described, but the base film 18 may be translucent. The base film 18 is a film made of resin, for example. The base film 18 is provided, for example, between the hard coat layer 11 and the front side toning layer 12 . In the decorative sheet 8 , the base film 18 supports the hard coat layer 11 , front side toning layer 12 , pattern layer 13 , back side toning layer 14 , shielding layer 15 and adhesive layer 16 .

(2) Detailed configuration (2-1) Hard coat layer 11
The hard coat layer 11 is a protective layer having a higher degree than the base film 18 or the molded member 17 made of resin. Examples of materials for the hard coat layer 11 include UV-curable and ionizing radiation-curable resins such as polyester acrylate and urethane acrylate, and thermosetting resins such as acrylic and urethane-based resins. The hard coat layer is preferably formed to exhibit a hardness of HB or higher in a pencil hardness test (load of 750 g) according to JISK5600-5-4.

(2-2) Pattern layer 13
The pattern 100 of the pattern layer 13 is formed of an interference pigment 21 that develops color by interference of the reflected light RL1.
FIG. 4 schematically shows an example of the cross-sectional structure of particles of the interference pigment 21 . The interference pigment 21 has, for example, a core portion 201 and a thin shell portion 202 covering the core portion 201 . Both the core portion 201 and the shell portion 202 transmit visible light. The core portion 201 and the shell portion 202 are made of materials with different refractive indices. For example, the core portion 201 has a smaller refractive index than the shell portion 202 . Arrows Ar2 and Ar3 indicate incident light incident on the shell portion 202 of the interference pigment 21 . Part of the incident light indicated by arrow Ar3 travels through shell portion 202 and is reflected by core portion 201 to become reflected light indicated by arrow Ar31. Part of the incident light indicated by arrow Ar2 is reflected by the surface of shell portion 202 and becomes reflected light indicated by arrow Ar21. The reflected light indicated by the arrow Ar21 and the reflected light indicated by the arrow Ar31 interfere and strengthen each other, so that the interference light of a specific wavelength is strongly visually recognized. The reflected light indicated by arrow Ar21 and the reflected light indicated by arrow Ar31 are, for example, reflected light RL1 shown in FIGS.
For example, a blue interference pigment can be obtained by adjusting the thickness of the shell portion 202 so that the wavelength intensified by interference is a blue wavelength.
Visible light emitted from the light source 2 also enters the interference pigment 21 . The light incident on the interference pigment 21 indicated by the arrow Ar4 in FIG. 4 is the incident light IL2. Visible light indicated by an arrow Ar4 enters the interference pigment 21, passes through the interference pigment 21, and leaves the interference pigment 21 in the opposite direction. Visible light transmitted through the interference pigment 21 is transmitted light indicated by an arrow Ar41. Transmitted light indicated by arrow Ar41 contributes to the display of icon 110 .
The pattern layer 13 transmits the incident light IL2 incident from the back surface 10b, and the light transmittance of the portion of the cover panel 10 where the light is transmitted from the back surface 13b of the pattern layer 13 to the front surface 13a is 10% or more50%. % or less. In the first embodiment, the portion where light is transmitted from the back surface 13b of the pattern layer 13 to the front surface 13a is the portion where the icons 110 are arranged. By setting the transmittance of the portion where the icon 110 is arranged in this way, the portion covered by the cover panel 10 is prevented from being seen through the cover panel 10 . Since the icon 110 of the cover panel 10 shown here is small, even if the inside can be seen through the icon 110, it is not conspicuous. In order to prevent the contents of the part covered with the cover panel 10 from being seen, the light transmittance of the cover panel 10 in the part where the light is transmitted from the rear surface 13b to the front surface 13a of the pattern layer 13 is particularly important.

As shown in FIG. 5, if the reflection angles of the incident light IL1 and the reflected light RL1 impinging on the interference pigment 21 are different from the reflection angles of the incident light IL1w and the reflected light RL1w, the paths of the light are different. also change. Moreover, if the reflection angles of the incident light IL1 and the reflected light RL1 are different from the reflection angles of the incident light IL1w and the reflected light RL1w, the reflectance will also be different, so the magnitude of the spectral component included in the interference light will also change. In addition, when the above-mentioned reflection angle changes, the ratio of spectral components for each frequency included in the interference light also changes.
For example, the angle of reflection between the incident light IL1w and the reflected light RL1w is larger than that between the incident light IL1 and the reflected light RL1, so the reflected light RL1w is stronger than the reflected light RL1. In addition, the reflected light RL1w differs in color from the reflected light RL1 because the magnitude of the included spectral component differs for each frequency.

(2-3) Front side toning layer 12
The front side toning layer 12 is a layer in which the front side absorption pigment 22 is uniformly dispersed in a transparent binder resin. The thickness of the front side toning layer 12 is, for example, 0.5 μm to 5 μm. The front-side absorption pigment 22 reduces spectral components of wavelengths within a predetermined range from the incident light IL1, IL1w and the reflected light RL1, RL1w that pass through the front-side toning layer 12. FIG.
Since the reflection angles of the incident light IL1w and the reflected light RL1w are larger than the reflection angles of the incident light IL1 and the reflected light RL1, the distance the incident light IL1 and the reflected light RL1 travel in the front side toning layer 12 is relatively large. The distance that IL1w and reflected light RL1w travel through the front side toning layer 12 increases. The interference pigment 21 intensifies the reflected light RL1w more than the reflected light RL1, but the front-side absorption pigment 22 greatly reduces spectral components in a predetermined range of wavelengths from the reflected light RL1w traveling a long distance in the front-side toning layer 12. be able to. The front-side absorption pigment 22 can mitigate the intensity of the reflected light RL1w relative to the reflected light RL1.
The change in color caused by the difference in reflection angle between the incident lights IL1, IL1w and the reflected lights RL1, RL1w can also be mitigated by appropriately setting the wavelengths in the predetermined range of the spectral components that the front-side absorption pigment 22 reduces. . For example, when it is felt that the brown spectral component of the reflected light RL1 is lighter than the reflected light RL1, the predetermined range of the front side absorption pigment 22 is set to a range other than the brown spectral component. With such a setting, it is possible to alleviate the feeling that the brown color of the reflected light RL1w is lightened due to the difference in reflection angle between the incident light IL1, IL1w and the reflected light RL1, RL1w. In this case, the reflected light RL1w travels a longer distance in the front side toning layer 12 than the reflected light RL1. It becomes easy to increase the ratio of brown spectral components outside the predetermined range of . As a result, it is possible to alleviate the viewer's feeling that the reflected light RL1w has made the brown color lighter.

(2-4) Back side toning layer 14
The back side toning layer 14 is a layer in which the back side absorption pigment 23 is uniformly dispersed in a transparent binder resin. The thickness of the backside toning layer 14 is, for example, 0.5 μm to 5 μm. The backside absorbing pigment 23 reduces spectral components in a wavelength range different from that of the front side absorbing pigment 22 from the incident light IL2 transmitted through the backside toning layer 14 . The transmittance of the front side toning layer 12 is preferably higher than the light transmittance of the back side toning layer 14 in order to make the pattern 100 of the pattern layer 13 easier to see.
The incident light IL2 from the light source 2 is colored by the front-side absorption pigment 22 . Therefore, by adjusting the spectral components that the back-side absorption pigment 23 reduces, the coloring of the incident light IL2 by the front-side absorption pigment 22 is alleviated. In other words, the unfavorable color change of the icon 110 caused by the front side absorption pigment 22 is mitigated by making the absorption properties of the back side absorption pigment 23 appropriate.

(2-4-1) When approximating an achromatic color In the back absorption pigment 23, the light passing through the two layers of the back side toning layer 14 and the front side toning layer 12 is changed to the light passing only through the front side toning layer 12. Pigments can be used that have light-absorbing properties that make them more achromatic in comparison.
In the xy chromaticity diagram of CIE 1931 in FIG. 6, the color of light transmitted only through the front side toning layer 12 is indicated by "*", and the color of light transmitted through only the back side toning layer 14 is indicated by "Δ". The color of light transmitted through layer 12 and back toning layer 14 is indicated by "□". In other words, “□” indicates the overlapping color of the front side toning layer 12 and the back side toning layer 14 . The color of light (white) that did not pass through the front side toning layer 12 or the back side toning layer 14 is indicated by "o". Here, the illumination light (light source color) of the light source 2 is white. In other words, in the xy chromaticity diagram of CIE 1931, the point indicated by "o" is the white point.
If only the front side toning layer 12 is used, the color of the transmitted light that is shifted to the position of "*" is adjusted to the color of the position of "□" by adding the back side toning layer 14, and is indicated by "○". matches or approximates the white
For example, the color of light indicated by "♦" is transmitted through the front side toning layer 12 and the back side toning layer 14 when the back side absorption pigment 23 is changed to a color different from the back side absorption pigment 23 in FIG. is the color of the light. The color of light indicated by "◆" is far from the point (white point) indicated by "〇" compared to the color of light indicated by "□", but Closer to the white point than the color of the light shown. Therefore, even if the color of the light transmitted through the front side toning layer 12 and the back side toning layer 14 becomes the color of light indicated by "♦", it is close to achromatic color.
In addition, the back absorption pigment 23 does not transmit light passing through the three layers of the back toning layer 14 , the pattern layer 13 and the front toning layer 12 as compared to the light passing through the pattern layer 13 and the front toning layer 12 . Pigments can be used that have light absorption properties that approximate coloration. In this case, the color of the incident light IL2 from the back surface 10b of the cover panel 10 colored by the pattern layer 13 and the front toning layer 12 can be adjusted by the back toning layer 14 toward an appropriate color. .

(2-4-2) When the front toning layer 12 and the back toning layer 14 have complementary colors You may Here, complementary colors refer to a combination of colors that are oppositely positioned on the color wheel. When the color of the front side toning layer 12 and the color of the back side toning layer 14 are complementary to each other, the front side toning layer 12 and the back side toning layer 14 are colored by the front side toning layer 12 because an achromatic color can be produced by the front side toning layer 12 and the back side toning layer 14.例文帳に追加can be suppressed. Alternatively, the color of the front absorption pigment 22 and the color of the back absorption pigment 23 may be complementary to each other. When the colors of the front side absorption pigment 22 and the back side absorption pigment 23 are complementary to each other, the front side absorption pigment 22 and the back side absorption pigment 23 can produce an achromatic color, so that coloring by the front side toning layer 12 can be suppressed. can.
(2-4-3) When a point (x, y) on the xy chromaticity diagram satisfies a predetermined condition Absorbing pigments having light absorption properties such that the point (x, y) satisfies the conditions 0.28≤x≤0.36 and 0.28≤y≤0.36 may also be used. The location where the icon 110 is located is the specific location where the color of the light should be adjusted. In this case, when the back side toning layer 14 is configured in this way, the color of the icon 110 is colored by portions other than the back side toning layer 14 from the molding member 17 to the hard coat layer 11, and is different from white. You can prevent it from becoming tinted. In other words, when the back side toning layer 14 is configured in this way, the color of the icon 110 can be adjusted to white.
Alternatively, in this case, the back absorption pigment 23 is the xy chromaticity of light transmitted to the front side of the icon 110 of the cover panel 10 when the point on the xy chromaticity diagram of the color of the light source 2 is (x1, y1). A point (x, y) on the figure satisfies the conditions of (x1-0.03)≤x≤(x1+0.03) and (y1-0.03)≤y≤(y1+0.03). Absorption pigments with absorption properties are used. By using the back side absorbing pigment 23 having such absorption characteristics, the color of the incident light IL2 transmitted from the back side 10b to the front side 10a of the cover panel 10 can be adjusted so as to approach the color of the light source 2.
For example, as shown in FIG. 7, a point (x1, y1 )=(0.314, 0.331), the color of light transmitted through the overlapped portion of the front side toning layer 12, the pattern layer 13, and the back side toning layer 14 is (0.312, 0.329) , (x1-0.03)≤0.312≤(x1+0.03), and (y1-0.03)≤0.329≤(y1+0.03). If the front side toning layer 12, the pattern layer 13, and the back side toning layer 14 are set as shown in FIG. The icon 110 can be displayed in a color very close to the color of the light source 2 .
For example, as shown in FIG. 8, when the color of the light source 2 is light green, it is assumed that the light green of the light source is colored by the front side toning layer 12 and shifted to the position of "*". In FIG. 8 , “●” indicates the light source color, which is the color of the light emitted from the light source 2 . By transmitting through the front side toning layer 12 and the pattern layer 13, the color of the transmitted light that shifts to the position of "*" if only the front side toning layer 12 is used is adjusted by the back side toning layer 14 of the color of "△". By doing so, the original light green color of the light source 2 can be restored.
Note that FIG. 8 describes the case where the light source color is not white, but the light source color may be white.

(2-5) Shielding layer 15
The shielding layer 15 has low light transmittance at predetermined locations. The shielding layer 15 has, for example, a light transmittance at a predetermined location close to 0 and is black. The shielding layer 15 is formed by printing ink in which a black absorbing pigment is dispersed in a resin, for example. The opening 15a for representing the icon 110 is, for example, a portion not printed with ink.
(2-6) Adhesive layer 16
The adhesive layer 16 is a layer for bonding the decorative sheet 8 to the molded member 17, or a transfer layer including the hard coat layer 11, the front side toning layer 12, the pattern layer 13, the back side toning layer 14, and the shielding layer 15. is a layer for adhering to the molded member 17 . The adhesive layer 16 can transmit visible light. The thickness of the adhesive layer 16 is set within a range of 1 μm to 50 μm, for example. The adhesive layer 16 is mainly made of, for example, an acrylic resin, a urethane resin, a polyester resin, a polyvinyl acetate resin, a vinyl chloride resin, or a vinyl chloride-vinyl acetate copolymer. Secondary materials may include polymeric materials, for example to improve adhesion.
(2-7) Base film 18
The thickness of the base film 18 is selected, for example, from a range of 10 μm to 1000 μm. At least one of a light-transmitting resin and a light-transmitting elastomer is used for the base film 18, for example. The base film 18 made of resin is, for example, polyester resin, polyethylene terephthalate (PET) resin, acrylic resin, polycarbonate resin, polybutylene terephthalate (PBT) resin, triacetyl cellulose resin, styrene resin, ABS resin film, acrylic resin, or the like. It is selected from a multilayer film of resin and ABS resin or a multilayer film of acrylic resin and polycarbonate resin. As the elastomer used for the base film 18, for example, thermoplastic elastomer (TPE) can be used. Thermoplastic elastomers include, for example, amide-based TPE (TPA), ester-based TPE (TPC), olefin-based TPE (TPO), styrene-based TPE (TPS), and urethane-based TPE (TPU). The base film 18 may be a film obtained by laminating a resin film and an elastomer film.
Note that the base film 19 does not have to have optical transparency, but for example, the same film as the base film 18 can be used.

By using the back side absorbing pigment 23 having such absorption characteristics, the color of the incident light IL2 transmitted from the back side 10b of the cover panel 10 to the front side 10a can be adjusted to white. Although the display location of the icon 110 is shown as an example of the specific location, the specific location is not limited to the display location of the icon 110 .

<Second embodiment>
(4) Overall Configuration In the first embodiment described above, the case where the present invention is applied to the cover panel 10 has been mainly described.
In the second embodiment, a case where the present invention is applied to a display device 50 as shown in FIGS. 18, 19 and 20 will be described.
The display device 50 is provided with a display screen 55 in addition to the icons 110 . 18 and 19 show the state in which the display device 50 is separated at the interface between the shielding layer 15 and the backside toning layer 14 for the sake of explanation.
The display device 50 includes a hard coat layer 11, a front side toning layer 12, a pattern layer 13, a back side toning layer 14, a shielding layer 15, an adhesive layer 16, a molding member 17, an optically transparent adhesive 52, and a display 51. there is The display 51 can emit light to display an image. The hard coat layer 11, the front side toning layer 12, the pattern layer 13, the back side toning layer 14, the shielding layer 15, the adhesive layer 16, and the molding member 17 can be configured in the same manner as the cover panel 10 of the first embodiment. Description is omitted here. However, in the shielding layer 15, not only the opening 15a for displaying the icon 110 but also the opening 15b for displaying the display screen 55 are formed in the central portion. The molding member 17 is, for example, a transparent resin plate or a transparent glass plate. When the molding member 17 is a glass plate, the hard coat layer 11, the front side toning layer 12, the pattern layer 13, the back side toning layer 14, the shielding layer 15, and the adhesive layer 16 are formed by printing, for example. In the display device 50, the shielding layer 15 is arranged along the outer edge of the display 51 and functions as an outer frame member that shields light. Although the shielding layer 15 is used as the outer frame member here, a structure other than the shielding layer 15 may be used as the outer member. For example, a light-shielding resin thin plate can be used as the outer frame member.
When the display 51 of the display device 50 is in the OFF state, the wood grain pattern 100 is displayed on the front side of the display device 50 . When the display 51 is in the OFF state and no light is emitted from the display 51, the display screen 55 and the icons 110 are not displayed as shown in FIG. The display 51 of the display device 50 is turned on, and the display screen 55 and the icon 110 are displayed.

A space between the molded member 17 and the display 51 is filled with an optically transparent adhesive 52 . With such a configuration, no air layer exists between the molded member 17 and the display 51 . If an air layer exists between the molded member 17 and the display 51, reflection occurs at the boundary between the molded member 17 and the air layer, which have a large difference in refractive index. If reflection occurs at the boundary between the molding member 17 and the air layer, the display screen 55 may be highlighted by the reflected light, and the value of the design 100 of the display device 50 may be lowered. Therefore, an optically transparent adhesive 52 is inserted between the molding member 17 and the display 51 so that the molding member 17 does not face the air layer. By filling the space between the molded member 17 and the display 51 with the optically transparent adhesive 52 in this manner, the portion where the display screen 55 exists and the portion of the outer frame member where the display screen 55 does not exist (light shielding layer 15). It is possible to reduce the difference in appearance with the part that blocks the
Here, the optically transparent adhesive is an adhesive with excellent transparency or a pressure-sensitive adhesive with excellent transparency. is included.
Regarding the display device 50 of the second embodiment, the reflected lights RL1 and RL2 and the incident light IL2 are displayed by the front side toning layer 12 and the back side toning layer 14 in the same manner as in the first embodiment and modifications 1A to 1G. The color when transmitted to the front side of the device 50 can be adjusted, and a metallic layer 30 may be added.

<Third Embodiment>
(5) Overall Configuration In the above-described first embodiment, the case where the opening 15a through which light passes through the shielding layer 15 is irrelevant to the pattern shape of the pattern layer 13 has been described. However, the pattern layer may have a pattern that has the same or similar shape as the opening and overlaps the opening. That is, the configuration of the third embodiment can be applied to the decorative sheets 8 and 9, the cover panel 10, and the display device 50 described in the first and second embodiments.
30 and 31 show the shielding layer 15 having linear openings 15a. A line pattern 13c having the same shape as the linear opening 15a shown in FIGS. 30 and 31 is formed. That is, the first shape, which is the shape of the opening 15a, is the same as or similar to the second shape, which is the shape of the line pattern 13c. As shown in FIG. 31, wood grain patterns 13d are formed on both sides of the line pattern 13c in plan view. Here, the case where the first shape and the second shape are linear will be described, but the first shape and the second shape are not limited to linear. The first shape and the second shape can be, for example, circular, toric, fan-shaped, elliptical, oval, triangular, square, rectangular, trapezoidal, pentagonal, hexagonal, other polygonal, star-shaped, various curves. Other two-dimensional shapes, such as a shape that is a combination of
FIG. 32 shows three examples of the relationship between the line width of the opening 15a and the width of the line pattern 13c. The case where the width of the line pattern 13c is larger than the line width of the opening 15a corresponds to "the case where the pattern is larger than the opening" shown in FIG. The case where the width of the line pattern 13c is smaller than the line width of the opening 15a corresponds to "the case where the pattern is smaller than the opening" shown in FIG. The case where the width of the line pattern 13c and the line width of the opening 15a are the same corresponds to "the case where the opening and the pattern are the same size". The relationship between the length of the opening 15a and the length of the line pattern 13c is the same as the relationship between the widths. When the width of the line pattern 13c is larger than the line width of the opening 15a, the width of the overlapping portion of the line pattern 13c and the shielding layer 15 is, for example, 2 mm. The width of this overlapping portion may be 1 mm or less. When the width of the line pattern 13c is smaller than the line width of the opening 15a, the width of the gap between the line pattern 13c and the shielding layer 15 is, for example, 2 mm. The width of this gap may be 1 mm or less.
Usually, the width of the line pattern 13c is often made larger than the line width of the opening 15a. For example, as shown in FIG. 31, even if the width of the line pattern 13c is larger than the line width of the opening 15a, since the interference pigment is used in the pattern layer 13, the wood grain pattern 13d is formed by the transmitted light. Prevent visible defects. Further, since the interference pigment is used in the pattern layer 13, it is possible to suppress the influence of the shielding layer 15 on the line pattern 13c when the transmitted light is not used. In other words, it is possible to prevent the line pattern 13c from appearing to be shaded by the shielding layer 15. FIG.

FIG. 33 shows three layers of pattern layer 13 and shielding layer 15 . A linear line pattern 13c is drawn with an interference pigment on the pattern layer 13 on the frontmost side. The shielding layer 15 is formed with linear openings 15a corresponding to the line patterns 13c. The line pattern 13c shown in FIG. 33 consists of a transmissive portion corresponding to the linear opening 15a and a non-transmissive portion extending from the transmissive portion. The transparent portion of the line pattern 13c has the same shape as or a similar shape to the shape of the opening 15a.
FIG. 34 shows side by side photographed images of the cover panel 10 having the configuration of FIG. 33 in the "reflective state" and the "transmissive state". In the reflective state, the reflected light reflected by each of the three pattern layers 13 can be seen. Therefore, in the reflective state, the image of the opening 15a of the shielding layer 15 is not visible. In the transmissive state, transmitted light passing through the shielding layer 15 and further through the three pattern layers 13 can be seen. Therefore, in the transmissive state, an image having the shape of the opening 15a of the shielding layer 15 is seen by the transmitted light. The image having the shape of the opening 15a is particularly colored by the line pattern 13c. Here, although the transmission light is configured to be transmitted through only part of the line pattern 13c, the transmission light may be configured to be transmitted through the entire line pattern 13c.

(6) Modification (6-1) Modification 3A
The said 3rd Embodiment demonstrated the structure by which the line pattern 13c is arrange|positioned on the back side of the front side toning layer 12. As shown in FIG. However, as shown in FIG. 35, the line pattern 13c may be arranged on the front side of the front side toning layer 12. FIG. When the line pattern 13c is arranged on the front side of the front side toning layer 12, the reflected light of the line pattern 13c does not pass through the front side toning layer 12.例文帳に追加As shown in FIG. 35, by arranging the line pattern 13c on the front side of the front toning layer 12, the color of the line pattern 13c by reflected light can be shown.
(6-2) Modification 3B
In the third embodiment and modification 3A described above, the pattern layer 13 not including the line pattern 13c is formed in addition to the pattern layer 13 including the line pattern 13c. However, the pattern layer 13 applied to the decorative sheets 8 and 9, the cover panel 10, and the display device 50 described above has a shape that is the same as or similar to the shape of the opening 15a of the shielding layer 15, such as the line pattern 13c. Only one pattern layer 13 including a shape having a shape may be used.
FIG. 36 shows an example in which only the pattern layer 13 including the line pattern 13c is arranged between the front side toning layer 12 and the back side toning layer 14. FIG. In FIG. 36, the shielding layer 15, the back side toning layer 14, the pattern layer 13 including the line pattern 13c, and the front side toning layer 12 are arranged in order from the back side. The first shape, which is the shape of the opening 15a, is the same as or similar to the second shape, which is the shape of the line pattern 13c.
FIG. 37 shows an example in which only the pattern layer 13 including the line pattern 13c is arranged on the front side of the two-layered back side toning layer 14. FIG. Although the configuration of FIG. 37 shows the case where the back side toning layer 14 is two layers, the back side toning layer 14 may be one layer. In FIG. 37, shielding layer 15, first back side toning layer 14, second back side toning layer, and pattern layer 13 including line pattern 13c are arranged in order from the back side. The first shape, which is the shape of the opening 15a, is the same as or similar to the second shape, which is the shape of the line pattern 13c.

(7) Features (7-1)
3, 10, 12, 14, 15, and 17 and the decorative sheet 9 shown in FIG. A glossy appearance is suppressed by the front side absorption pigment 22 of the front side toning layer 12.例文帳に追加Moreover, the impression that the color of the pattern 100 given to the viewer is changed depending on the angle at which the pattern 100 is viewed can be alleviated by setting a predetermined range of spectral components to be reduced by the front side toning layer 12 .
For example, FIG. 21A shows a photographed image of the design portion of the cover panel 10 viewed from the front when the front toning layer 12 is not provided, and FIG. 21B shows the front toning layer 12 provided. A photographed image of the design part of the cover panel 10 when there is no cover panel 10 is shown obliquely. In addition, FIG. 22A shows a photographed image of the pattern portion of the cover panel 10 when the front toning layer 12 is provided, and FIG. A photographed image of the design part of the cover panel 10 when the cover panel 10 is obliquely viewed is shown. Comparing FIG. 21B and FIG. 22B, it can be seen that the front side toning layer suppresses the lustrous appearance of the pattern like pearls.

In such a case, the back side absorption pigment 23 of the back side toning layer 14 makes the light passing through the back side toning layer 14 and the front side toning layer 12 achromatic compared to the case where only the front side toning layer 12 is passed. be changed to be closer to Unfavorable coloring caused by the front side toning layer 12 can be suppressed by such a function of the back side toning layer 14 .
For example, FIG. 23A shows a photographed image of the icon of the cover panel when the back side toning layer 14 is provided, and FIG. A photographed image of the icon is shown. A comparison of FIG. 23A and FIG. 23B reveals that the back side toning layer works to suppress undesirable coloring caused by the front side toning layer.

(7-3)
As described with reference to FIG. 6, in the decorative sheets 8 and 9, when the color of the front side toning layer 12 and the color of the back side toning layer 14 are complementary to each other, the back side toning layer 14 and the light passing through the front toning layer 12 can be achromatic. According to such a configuration, the back side toning layer 14 can suppress undesirable coloring of transmitted light from the back side 13b of the pattern layer 13 toward the front side 13a.
(7-4)
As described with reference to FIG. 7, the back absorption pigment 23 is, for example, an xy A point (x, y) on the chromaticity diagram is configured to have light absorption characteristics satisfying the conditions of 0.28≦x≦0.36 and 0.28≦y≦0.36. In the decorative sheets 8 and 9 having the back side toning layer 14, the pattern layer 13, and the front side toning layer 12 as described in FIG. It may be colored by the toning layer 12 and not be white. In such a case, the point (x, y) on the xy chromaticity diagram of the light of the icon 110 transmitted through the back side toning layer 14, the pattern layer 13, and the front side toning layer 12 by the back side absorption pigment 23 is The conditions of 0.28≤x≤0.36 and 0.28≤y≤0.36 are satisfied. As a result, it is possible to prevent the light of the icon 110 passing through the back side toning layer 14, the pattern layer 13, and the front side toning layer 12 (example of light passing through a specific portion) from being colored in a color other than white. can.

(7-5)
In the decorative sheet 8 shown in FIGS. 11, 13, and 16, the white transmitted light from the back surface 13b of the pattern layer 13 to the front surface 13a may be colored by the ground color of the pattern layer 13 and may not be white. In such a case, the back absorption pigment 23 changes the point (x, y) on the xy chromaticity diagram of the light that passes through the back side toning layer 14 and the pattern layer 13 at a specific location (for example, the location of the icon 110). , 0.28≤x≤0.36 and 0.28≤y≤0.36. As a result, it is possible to suppress the light passing through the back side toning layer 14 and the pattern layer 13 from being colored white.
As with the decorative sheet 8 shown in FIGS. 11, 13, and 16, in the decorative sheet 9 used for transfer, a decorative sheet without the front side toning layer 12 can be constructed. has the same effect as the decorative sheet 8 shown in FIGS.
(7-6)
For example, the back absorbing pigment 23 shown in FIG. , (0.28≤x≤0.36) and (0.28≤y≤0.36). In the cover panel 10 of FIG. 2, white transmitted light from the back surface 13b of the pattern layer 13 toward the front surface 13a is colored by the molding member 17, the back surface toning layer 14, the pattern layer 13, and the front surface toning layer 12, and is colored white. may disappear. In such a case, the back absorption pigment 23 allows the point (x, y) on the xy chromaticity diagram of the light of the icon 110 (example of light transmitted to the front side of a specific portion) to be 0.28≦x≦0. .36 and 0.28≤y≤0.36. As a result, it is possible to prevent the light passing through the cover panel 10 from being colored in a color other than white.

(7-7)
For example, with the back-side absorption pigment shown in FIG. 11, the point (x, y) on the xy chromaticity diagram of the light transmitted to the front side of a specific portion (for example, to the surface 10a side of the icon 110) is ( 0.28≦x≦0.36) and (0.28≦y≦0.36). In the cover panel 10 of FIG. 11, the white transmitted light from the back surface 13b of the pattern layer 13 to the front surface 13a is colored by the molding member 17, the back-side toning layer 14, and the pattern layer 13, and may not be white. In such a case, the back absorption pigment 23 allows the point (x, y) on the xy chromaticity diagram of the light of the icon 110 (example of light transmitted to the front side of a specific portion) to be 0.28≦x≦0. .36 and 0.28≤y≤0.36. As a result, it is possible to prevent the light passing through the cover panel 10 from becoming a color other than white.
(7-8)
When the light transmittance of the portion where the pattern layer 13 is provided is 10% or more and 70% or less, the cover panel 10 is covered with the cover panel 10 through the pattern layer 13 to the viewer of the pattern 100. It is possible to prevent the broken internal structure from being seen. In particular, the light transmittance of the portion where the shielding layer 15 is not provided (for example, the portion where the opening 15a for the icon 110 is formed) is set to 10% or more and 70% or less. In this case, the incident light IL1 from the back surface 10b of the cover panel 10 can be transmitted with sufficient intensity to display the icon 110, and the contents covered by the cover panel 10 can be seen through the opening 15a for the icon 110. can be suppressed.
(7-9)
The back absorption pigment 23 shown in FIGS. 2 and 20 is applied to the front side of a specific portion (for example, the icon 110) when the point on the xy chromaticity diagram of the color of the light source 2 or the display 51 is (x1, y1). The point (x, y) on the xy chromaticity diagram of the transmitted light (to the surface 10a side of the portion or the portion of the display screen 55) satisfies (x1−0.03)≦x≦(x1+0.03) and (y1 −0.03)≦y≦(y1+0.03).
In the display device 50 configured in this manner, the transmitted light from the back surface 13b of the pattern layer 13 to the front surface 13a is colored by, for example, the molding member 17, the back surface toning layer 14, the pattern layer 13, and the front surface toning layer 12, The color of the light may deviate from the color of the light source. In such a case, the back absorption pigment 23 causes the point (x, y) on the xy chromaticity diagram of the light of the icon 110 or the light of the display screen 55 (example of light transmitted to the front side of a specific portion) to be ( x1-0.03)≤x≤(x1+0.03) and (y1-0.03)≤y≤(y1+0.03). As a result, for example, it is possible to prevent the color of the icon 110 or the display screen from deviating from the color of the light from the light source 2 or the display 51 .

(7-10)
The back absorption pigment 23 shown in FIG. 11 is applied to the front side of a specific portion (for example, the surface 10a side of the icon 110) when the point on the xy chromaticity diagram of the color of the light source 2 is (x1, y1). ) the point (x, y) of the transmitted light on the xy chromaticity diagram is such that (x1-0.03) ≤ x ≤ (x1 + 0.03) and (y1-0.03) ≤ y ≤ (y1 + 0.03 ) has light absorption characteristics that satisfy the conditions of
In the display device 50 configured as described above, the transmitted light from the rear surface 13b to the front surface 13a of the pattern layer 13 is colored by the molding member 17, the rear-side toning layer 14, and the pattern layer 13, and is shifted from the color of the light from the light source. It may become a thing. In such a case, the back-side absorption pigment 23 causes the point (x, y) on the xy chromaticity diagram of the light of the icon 110 (example of light transmitted to the front side of a specific portion) to be (x1-0.03) Conditions of ≦x≦(x1+0.03) and (y1−0.03)≦y≦(y1+0.03) are satisfied. As a result, it is possible to prevent the color of the icon 110 from deviating from the color of the light from the light source 2 .
(7-11)
In the display device 50 shown in FIG. 20, since the optically transparent adhesive 52 does not create a gap between the molding member 17 and the display 51, there is no contact portion between the molding member 17 and the air layer. Therefore, the incident light IL1 incident from the surface 13a side of the pattern layer 13 is not reflected at the interface between the molding member 17 and the air layer. As a result, when the display 51 is not illuminated with light, it is possible to reduce the phenomenon that the boundary of the shielding layer 15, which is the outer frame member, is visible due to the reflected light at the interface with the air layer.
