Description

Technical Field

[0001] The present disclosure relates to a decorative material, a method for manufacturing a decorative material, and a laminate using the decorative material.

Background Art

[0002] Decorative materials are widely used for surface decoration of building interiors, building materials, furniture, fittings, architectural members, vehicles, household appliances, bathroom products such as unit baths, kitchen products, and the like. Such decorative materials include those in which a paper or resin sheet printed with a pattern is adhered to a base material, and those in which a pattern is formed on the surface of a metal plate such as a steel plate by printing.

[0003] In such decorative materials, by providing a coating layer containing a glitter pigment typified by a pearl pigment, a design property is imparted to cause a change in the visible color depending on the viewing angle and the adjustment of light. For example, in Patent Document 1, a decorative sheet is disclosed in which a coating layer containing a pearl pigment and a printing layer (pattern) are provided on a white base material to change the color tone and texture of the pattern.

[0013] Hereinafter, the cosmetic material of the present disclosure will be described in detail. In the present specification, the numerical range notation of "AA to BB" means "AA or more and BB or less".

[0014] [Cosmetic Material] The cosmetic material of the present disclosure is a cosmetic material having a phosphorescent pattern layer on a substrate, the phosphorescent pattern layer having at least a first phosphorescent ink layer and a second phosphorescent ink layer, the first phosphorescent ink layer and the second phosphorescent ink layer satisfying the following relationship (A) or (B), and when the cosmetic material is viewed in plan, each of the phosphorescent ink layers is provided on at least a part of the substrate, and when the cosmetic material is viewed in plan, the first phosphorescent ink layer has a region overlapping with the second phosphorescent ink layer and a region not overlapping with the second phosphorescent ink layer, and the second phosphorescent ink layer has a region overlapping with the first phosphorescent ink layer and a region not overlapping with the first phosphorescent ink layer. (A) The first phosphorescent ink layer contains a first phosphorescent pigment, and the second phosphorescent ink layer contains a second phosphorescent pigment different from the first phosphorescent pigment. (B) The first phosphorescent ink layer and the second phosphorescent ink layer contain phosphorescent pigments, and the content of the phosphorescent pigment in the first phosphorescent ink layer is different from the content of the phosphorescent pigment in the second phosphorescent ink layer.

[0015] First, the visual effect of the cosmetic material of the present disclosure will be described. FIG. 1 is a schematic plan view for explaining a cosmetic material according to an embodiment of the present disclosure. In the present disclosure, "plan view" means visually recognizing the cosmetic material of the present disclosure in a plane direction from the surface side (front side) where the phosphorescent pattern layer is provided. For example, in the XYZ coordinate system shown in FIG. 1, the plane represented by the X-axis direction and the Y-axis direction coincides with the surface of the cosmetic material, and "plan view" corresponds to viewing the surface of the cosmetic material from the positive Z-axis direction.

[0016] When the cosmetic material 10 in FIG. 1 is viewed from the surface side, a pattern formed by a phosphorescent pattern layer 12 and a region Ru (corresponding to a base material or a base coat layer to be described later, hereinafter referred to as a "base region") where the base of the phosphorescent pattern layer can be visually recognized is visible. In the present disclosure, the phosphorescent pattern layer is composed of at least two types of phosphorescent ink layers. The at least two types of phosphorescent ink layers include at least a first phosphorescent ink layer and a second phosphorescent ink layer. The first phosphorescent ink layer and the second phosphorescent ink layer satisfy the relationship of (A) or (B) above. The first phosphorescent ink layer and the second phosphorescent ink layer only need to satisfy one of the relationships of (A) and (B) above, but may also satisfy both. In this specification, regarding the embodiments of the phosphorescent ink layer, various embodiments may be separately described (for example, the embodiment of (A) and the embodiment of (B) may be separately described. Also, the embodiment of (C) to be described later and the embodiment of (D) to be described later may be separately described). However, unless otherwise specified, the various embodiments of the phosphorescent ink layer in this specification are the embodiments common to the various phosphorescent ink layers.

[0017] In the embodiment of (A) above, the first phosphorescent ink layer contains a first phosphorescent pigment, and the second phosphorescent ink layer contains a second phosphorescent pigment different from the first phosphorescent pigment. The first phosphorescent ink layer may contain only the first phosphorescent pigment, or may contain other phosphorescent pigments. When the first phosphorescent ink layer contains a plurality of types of phosphorescent pigments, it is preferably formulated so that the first phosphorescent pigment is the main component, and it is preferably free of the second phosphorescent pigment. Similarly, the second phosphorescent ink layer may contain only the second phosphorescent pigment, or may contain other phosphorescent pigments. When the second phosphorescent ink layer contains a plurality of types of phosphorescent pigments, it is preferably formulated so that the second phosphorescent pigment is the main component, and it is preferably free of the first phosphorescent pigment. That the first phosphorescent pigment or the second phosphorescent pigment is the main component means that the ratio of the first phosphorescent pigment or the second phosphorescent pigment to all phosphorescent pigments is 50% by mass or more. The ratio is preferably 70% by mass or more, more preferably 90% by mass or more, and still more preferably 100% by mass. Thus, in the embodiment of (A) above, by mainly including different phosphorescent pigments in the first phosphorescent ink layer and the second phosphorescent ink layer, the first phosphorescent ink layer and the second phosphorescent ink layer can be easily visually recognized as different layers. In particular, it is preferable that the first phosphorescent ink layer and the second phosphorescent ink layer have different colors from each other, because the difference in color between the layers becomes clear.

[0018] In the embodiment of (B) above, the first phosphorescent ink layer and the second phosphorescent ink layer contain a phosphorescent pigment, and the content of the phosphorescent pigment in the first phosphorescent ink layer is different from the content of the phosphorescent pigment in the second phosphorescent ink layer. In the embodiment of (B) above, the types of phosphorescent pigments contained in the first phosphorescent ink layer and the second phosphorescent ink layer may be the same or different. As described above, in the embodiment of (B) above, since the content of the phosphorescent pigment in the first phosphorescent ink layer is different from the content of the phosphorescent pigment in the second phosphorescent ink layer, it is easy to cause a difference in the number of stacked layers of the phosphorescent pigment in the first phosphorescent ink layer and the number of stacked layers of the phosphorescent pigment in the second phosphorescent ink layer. Therefore, in the embodiment of (B) above, a difference in luminance or color tone can be caused between the first phosphorescent ink layer and the second phosphorescent ink layer, and they can be easily visually recognized as different layers from each other.

[0019] Each of the first phosphorescent ink layer and the second phosphorescent ink layer can contain other pigments other than the phosphorescent pigment as necessary to adjust to a desired color.

[0020] The first phosphorescent ink layer and the second phosphorescent ink layer are preferably transparent or translucent. When the first phosphorescent ink layer and the second phosphorescent ink layer are transparent or translucent, it is easy to obtain the effect of color mixing due to the overlap of the first phosphorescent ink layer and the second phosphorescent ink layer as described later. Furthermore, the color derived from the base material can be easily visually recognized.

[0021] In the present disclosure, when the cosmetic material 10 is viewed in plan view, the first phosphorescent ink layer and the second phosphorescent ink layer are each provided on at least a part of the base material 14.

[0022] When the first phosphorescent ink layer is provided on a part of the base material 14, when the cosmetic material 10 is viewed in plan view, the first phosphorescent ink layer preferably consists of an aggregate of a plurality of independent regions (in FIG. 1, an aggregate of independent regions 16A-1 and 16A-2). Further, when the second phosphorescent ink layer is provided on a part of the base material 14, when the cosmetic material 10 is viewed in plan view, the second phosphorescent ink layer preferably consists of an aggregate of a plurality of independent regions (in FIG. 1, an aggregate of independent regions 16B-1 to 16B-3). In the present disclosure, a region including the edge of the cosmetic material 10 (base material 14) as a contour line as in reference numeral 16B-3 is also referred to as an "independent region". In FIG. 1, the first phosphorescent ink layer and the second phosphorescent ink layer have a plurality of independent regions. However, in the decorative material of the present disclosure, at least one of the first phosphorescent ink layer and the second phosphorescent ink layer may have only one independent region.

[0023] In the region indicated by the symbol F in FIG. 1, when the decorative material 10 is viewed in plan view, the first phosphorescent ink layer has a region (symbol Ro in FIG. 1) that overlaps with the second phosphorescent ink layer and a region (symbol Ra in FIG. 1) that does not overlap with the second phosphorescent ink layer. The second phosphorescent ink layer has a region (symbol Ro in FIG. 1) that overlaps with the first phosphorescent ink layer and a region (symbol Rb in FIG. 1) that does not overlap with the first phosphorescent ink layer.

[0024] In the present disclosure, there may be a region that does not overlap with other phosphorescent ink layers according to the pattern of the phosphorescent pattern layer 12. Specifically, the independent region 16A-2 of the first phosphorescent ink layer and the independent region 16B-2 of the second phosphorescent ink layer in FIG. 1 clearly do not overlap with the other phosphorescent ink layer.

[0025] When the decorative material 10 is viewed in plan view, the regions Ra and Rb exhibit the colors of the first phosphorescent ink layer and the second phosphorescent ink layer, respectively. The overlapping region Ro exhibits a mixed color of the color of the first phosphorescent ink layer and the color of the second phosphorescent ink layer. The phosphorescent ink layer containing a phosphorescent pigment has the property that the degree of luminance (strength) changes according to the combination of the incident angle of light on the decorative material and the angle at which the observer observes the decorative material (line-of-sight angle). Also, the degree of luminance changes depending on the distribution of the film thickness within the independent region described later and the degree of overlap of the phosphorescent ink layers (distribution of the film thickness in the overlapping region). In particular, Ro, which is the overlapping region, is likely to impart a more colorful luminance feeling compared to the other regions Ra and Rb. Furthermore, when a pearl pigment is used as the phosphorescent pigment, it is easy to cause a change in the hue of each of the regions Ra, Rb, and Ro according to the incident angle of light on the decorative material and the line-of-sight angle of the observer. Thus, the decorative material 10 of the present disclosure can easily represent the pattern of the luminous pattern layer in multiple colors or various luminances, and can easily represent more complex designs. Therefore, it is possible to obtain a decorative material having a design with excellent visual effects.

[0026] Furthermore, the base region Ru can be configured to exhibit a color derived from the base (base coat layer or base material) of the luminous pattern layer. In addition, since the luminous ink layer is transparent or translucent, the color of the base can also be visually recognized when observing the decorative material. Thus, in the decorative material of the present disclosure, various patterns can be represented by the pattern and color of the luminous pattern layer 12 and the color derived from the base.

[0027] In the present disclosure, it is preferable that at least one of the first luminous ink layer and the second luminous ink layer has a partially different film thickness.

[0028] When the first luminous ink layer is composed of an aggregate of a plurality of independent regions, when comparing the maximum film thicknesses of the individual independent regions, it is preferable that the maximum film thickness of at least one independent region is different from the maximum film thickness of the other independent regions. When the second luminous ink layer is composed of an aggregate of a plurality of independent regions, when comparing the maximum film thicknesses of the individual independent regions, it is preferable that the maximum film thickness of at least one independent region is different from the maximum film thickness of the other independent regions.

[0029] In addition, when the first luminous ink layer is partially provided as one independent region, the film thickness at any position within the independent region in plan view is preferably different from the film thickness at other positions within the independent region. Similarly, when the second luminous ink layer is partially provided as one independent region, the film thickness at any position within the independent region in plan view is preferably different from the film thickness at other positions within the independent region.

[0030] Further, when the cosmetic material is viewed in plan view, the first phosphorescent ink layer is composed of an aggregate of a plurality of independent regions, and it is preferable that at least one or more independent regions have partially different film thicknesses within the independent regions. When the cosmetic material is viewed in plan view, the second phosphorescent ink layer is composed of an aggregate of a plurality of independent regions, and it is preferable that at least one or more independent regions have partially different film thicknesses within the independent regions.

[0031] FIG. 2 is a schematic cross-sectional view of the phosphorescent ink layer in the cosmetic material of the present disclosure, and is a diagram for explaining that the film thickness of the phosphorescent ink layer is partially different. For simplicity of explanation, FIG. 2 shows an embodiment in which the first phosphorescent ink layer and the second phosphorescent ink layer do not overlap with each other's phosphorescent ink layers. For understanding of the present disclosure, in FIG. 2, for the independent regions, the dimension in the thickness direction is enlarged and emphasized compared to the dimension in the substrate surface direction. In the cosmetic material of the present disclosure, the ratio (dimension in the planar direction / dimension in the thickness direction) of the dimension in the planar direction to the dimension in the thickness direction of the independent region is 10 2 ~10 5 times. Therefore, in reality, the cross-section of the independent region can be a terrace type with a substantially flat top or a mountain type with a very gentle slope. In the present disclosure, the "cross-section" corresponds to the surface obtained by cutting the cosmetic material in the direction in which the base and the phosphorescent pattern layer are laminated. For example, it means the cross-section obtained by cutting the cosmetic material shown in FIG. 1 in the Z-axis direction.

[0032] As illustrated in FIG. 2, in the independent regions 20A-1 and 20A-2 of the first phosphorescent ink layer, the film thickness in the end regions is thinner than the film thickness in the central region. Also, let the maximum film thickness (the film thickness at the apex in the mountain-shaped independent region illustrated in FIG. 2) of the independent region 20A-1 be h a1 and the maximum film thickness of the independent region 20A-2 be h a2 Then, h a1 and h a2 are different.

[0033] Similarly, as illustrated in FIG. 2, in the independent regions 20B-1 and 20B-2 of the second phosphorescent ink layer, the film thickness of the end regions is thinner than that of the central portion. Also, let the maximum film thickness of the independent region 20B-1 (the film thickness at the apex in the mountain-shaped independent region illustrated in FIG. 2) be h b1 , and the maximum film thickness of the independent region 20B-2 be h b2 . Then, h b1 and h b2 are different.

[0034] The film thickness range of the phosphorescent ink layer (the film thickness range of the independent region) is not particularly limited. However, in order to obtain a sufficient visual effect, the maximum film thickness of the phosphorescent ink layer (independent region) is preferably 0.5 μm or more, and more preferably 1 μm or more. On the other hand, if the phosphorescent ink layer becomes too thick, it may be difficult to form by coating, resulting in a decrease in productivity, and there is also a risk of increasing production costs. Also, when the film thickness reaches a certain level or more, a visual effect commensurate with the increase in film thickness cannot be obtained, while there is a risk of problems such as peeling of the phosphorescent pattern layer and deterioration of the quality of the decorative material such as a decrease in touch feeling. Considering these, the maximum film thickness of the phosphorescent ink layer (independent region) is preferably about 20 μm or less, more preferably 15 μm or less, still more preferably 10 μm or less, and even more preferably 5 μm or less. Not only the first phosphorescent ink layer and the second phosphorescent ink layer, but also the third phosphorescent ink layer described later is preferably within the above-described maximum film thickness range. In the first phosphorescent ink layer, the second phosphorescent ink layer, and the third phosphorescent ink layer described later, when the film thickness is partially varied within one independent region, it is preferable to have a film thickness distribution in the range of 0.15 μm to 6.0 μm. The film thickness distribution is more preferably 0.20 μm to 4.0 μm.

[0035] When comparing the individual independent regions of the first phosphorescent ink layer and the second phosphorescent ink layer, as a means of varying the maximum film thickness between the independent regions, methods such as changing the specifications related to the ink transfer amount of the plate, such as the screen ruling, cell area, dot area, and plate depth, used when forming by various printing methods, can be mentioned. Among these means, control of the plate depth is preferable. Also, as a means of partially varying the film thickness within one independent region, the means related to the ink transfer amount of the plate described above can be mentioned, and further, means of reducing the leveling property of the ink can be mentioned. Among these means, control of the plate depth is preferable.

[0036] There is a correlation between the film thickness of the phosphorescent ink layer and the number of stacked phosphorescent pigments in the thickness direction of the phosphorescent ink layer. Specifically, the thicker the film thickness of the phosphorescent ink layer, the more the number of stacked phosphorescent pigments in the thickness direction of the phosphorescent ink layer tends to increase. And when the number of stacked phosphorescent pigments increases, the degree of multiple reflection between the phosphorescent pigments increases. For this reason, the thicker the film thickness of the phosphorescent ink layer, the easier it is to feel a darker color and the stronger the brightness is felt. As described above, by making the film thickness of the first phosphorescent ink layer or the second phosphorescent ink layer partially different, the degree of multiple reflection can be easily made partially different. For this reason, it is possible to easily change the natural change in color such as the shade of color and the strength and weakness of brightness depending on the location with the first phosphorescent ink layer and the second phosphorescent ink layer, and a more complex design can be expressed.

[0037] In the region where the first phosphorescent ink layer and the second phosphorescent ink layer overlap, it is preferable that at least either the film thickness of the first phosphorescent ink layer or the film thickness of the second phosphorescent ink layer is partially different. Figure 3 is a schematic cross-sectional view of the L-L' section of the region indicated by the symbol F in Figure 1. Figure 3 is an example in which the second phosphorescent ink layer is formed after the first phosphorescent ink layer is formed, and is an example in which the film thickness is partially changed within an independent region. Also in Figure 3, for the understanding of the present disclosure, the dimension in the thickness direction is enlarged and emphasized compared to the dimension in the substrate surface direction of the independent region. As described with reference to FIG. 2, the independent region 16A-1 of the first phosphorescent ink layer illustrated in FIG. 3 has a mountain-shaped cross-sectional shape. In the overlapping region Ro, the film thickness of the independent region 16A-1 continuously changes so as to gradually decrease from the center toward the end.

[0038] On the other hand, the independent region 16B-1 of the second phosphorescent ink layer illustrated in FIG. 3 is formed to have a mountain-shaped cross-sectional shape as in FIG. 2 when alone, but in the overlapping region Ro, the independent region 16B-1 rides on the independent region 16A-1. For this reason, in the overlapping region Ro, the hypotenuse is different from that in FIG. 2, but the film thickness of the independent region 16B-1 changes in the same manner as the independent region 16A-1. In FIG. 3, in the overlapping region Ro, the film thickness of the independent region 16B-1 continuously changes so as to gradually decrease from the center toward the end.

[0039] In FIG. 3, in the non-overlapping region Ra of the independent region 16A-1, by changing the film thickness of the first phosphorescent ink layer, it is possible to easily visually recognize the change in color shading and luminance as described above. Specifically, at a location where the film thickness is thick, the degree of multiple reflection by the phosphorescent pigment increases, making the color appear darker and the luminance stronger and easier to see, while at a location where the film thickness is thin, the color appears lighter and the luminance is weaker and easier to see. Similarly, in the non-overlapping region Rb of the independent region 16B-1, by changing the film thickness of the second phosphorescent ink layer, it is easy to visually recognize the shading of color and the intensity of luminance.

[0040] In FIG. 3, within the region Ro, since the film thicknesses of the first phosphorescent ink layer and the second phosphorescent ink layer are different, it is likely to achieve color mixing and luminance according to the film thickness ratio of the first phosphorescent ink layer and the second phosphorescent ink layer. Specifically, when the film thickness of the first phosphorescent ink layer is thicker, the color of the region Ro is likely to be a color mixture close to that of the first phosphorescent ink layer. When the film thickness of the second phosphorescent ink layer is thicker, the color of the region Ro is likely to be a color mixture close to that of the second phosphorescent ink layer. Furthermore, the total film thickness of the first phosphorescent ink layer and the second phosphorescent ink layer in the region Ro can easily express shading. Specifically, as the total film thickness increases, due to the effect of multiple reflections by the phosphorescent pigment, the color of the region Ro becomes darker and the luminance is also likely to become stronger. Therefore, the pattern formed by the first phosphorescent ink layer and the second phosphorescent ink layer can be easily expressed not only by color changes but also by shading and the intensity of luminance. By continuously changing the film thickness within the independent regions 16A-1 and the independent regions 16B-1, it is easy to express natural color changes, shading, and luminance changes. Further, as shown in FIG. 3, when the film thicknesses of the first phosphorescent ink layer and the second phosphorescent ink layer change gradually from the center toward the ends in the overlapping region Ro, it is easy to express continuous changes (gradations) in color and luminance.

[0041] As described above, by partially changing the film thickness of the phosphorescent ink layer, in addition to the three elements of color (hue, lightness, and chroma), luminance is also included, making it easier to express various colors. Therefore, it is possible to obtain a decorative material having a design with particularly excellent visual effects. According to the present disclosure, it is easy to obtain a decorative material excellent in reproducing various design appearances of a metal surface, which is caused by the formation of a thin film of a metal compound such as an oxide film on the surface by various methods such as heating in air or water vapor, chemical reactions with various chemicals, and electrochemical treatment.

[0042] In FIG. 1, for the sake of simplicity, the independent regions of the first phosphorescent ink layer and the second phosphorescent ink layer are represented as circles, ellipses, and elliptical sectors, but the present disclosure is not limited thereto. The shape of the independent region when viewed in plan may be a simple shape such as a triangle or a quadrilateral, a shape combining a plurality of such simple shapes, or a complex shape (so-called "irregular shape") that needs to be approximated by a combination of complex functions such as polynomials and infinite series.

[0043] The size (area) of each individual independent region is not particularly limited, but it should be a visible size and preferably set in consideration of the design (pattern of the phosphorescent pattern layer). Also, from the perspective of productivity when forming the phosphorescent pattern layer by printing, it is preferable that the independent regions have a certain size (area). For example, for any independent region, the width of the independent region measured so as to pass through the center of the circumscribed circle of the independent region is preferably in the range of about 5 mm to 60 cm.

[0044] Also, there are no particular restrictions on the intervals between independent regions, the number of independent regions provided as each phosphorescent ink layer, and the positions where each independent region is formed. These can be appropriately set according to the pattern of the phosphorescent ink layer required to obtain a phosphorescent pattern layer with a predetermined pattern.

[0045] The area ratio of the phosphorescent pattern layer to the entire surface of the cosmetic material, the area ratio between the first phosphorescent ink layer and the second phosphorescent ink layer in the plane of the cosmetic material, the area ratio of the overlapping region of the first phosphorescent ink layer and the second phosphorescent ink layer in the plane of the cosmetic material, the area ratio of the regions Ro, Ra, Rb, Ru, etc. can be appropriately set according to the pattern of the phosphorescent pattern layer.

[0046] FIG. 4 is a schematic plan view for explaining a cosmetic material according to an embodiment of the present disclosure, and is an example in which three types of phosphorescent ink layers (a first phosphorescent ink layer, a second phosphorescent ink layer, and a third phosphorescent ink layer) are formed as the phosphorescent pattern layer. In the present disclosure, it is also possible to provide four or more types of phosphorescent ink layers. The third phosphorescent ink layer satisfies the following relationship (C) or (D). (C) The third phosphorescent ink layer contains a third phosphorescent pigment different from the first phosphorescent pigment and the second phosphorescent pigment. (D) The third phosphorescent ink layer contains a phosphorescent pigment, and the content ratio of the phosphorescent pigment in the third phosphorescent ink layer is different from the content ratio of the phosphorescent pigment in the first phosphorescent ink layer and the content ratio of the phosphorescent pigment in the second phosphorescent ink layer. The third phosphorescent ink layer only needs to satisfy one of the above relationships (C) and (D), but it may also satisfy both.

[0047] In the embodiment of the above (C), the third phosphorescent ink layer contains a third phosphorescent pigment different from the first phosphorescent pigment and the second phosphorescent pigment. The pigment contained in the third phosphorescent ink layer may be only the third phosphorescent pigment or a mixture with other phosphorescent pigments. In addition, each of the third phosphorescent ink layers can contain other pigments other than the phosphorescent pigment as necessary to adjust to a desired color. When the third phosphorescent ink layer contains a plurality of types of phosphorescent pigments, it is preferably formulated so that the third phosphorescent pigment becomes the main component, and it is preferably not contain the first phosphorescent pigment and the second phosphorescent pigment. Specifically, the ratio of the third phosphorescent pigment to all the phosphorescent pigments is preferably 50% by mass or more, more preferably 70% by mass or more, still more preferably 90% by mass or more, and still more preferably 100% by mass. In the embodiment of the above (C), since the third phosphorescent ink layer contains a third phosphorescent pigment different from the first phosphorescent pigment and the second phosphorescent pigment, it exhibits a color different from that of the first phosphorescent ink layer and the second phosphorescent ink layer. In particular, it is preferable that the colors of the first phosphorescent ink layer, the second phosphorescent ink layer, and the third phosphorescent ink layer are different from each other, because the difference in the colors of each layer becomes clear. The embodiment of the above (C) is preferably combined with the embodiment of the above (A).

[0048] In the above-described embodiment (D), the content ratio of the phosphorescent pigment in the third phosphorescent ink layer is different from the content ratio of the phosphorescent pigment in the first phosphorescent ink layer and the content ratio of the phosphorescent pigment in the second phosphorescent ink layer. In the above-described embodiment (D), the type of the phosphorescent pigment contained in the third phosphorescent ink layer may be the same as or different from the types of the phosphorescent pigments contained in the first phosphorescent ink layer and the second phosphorescent ink layer. In the above-described embodiment (D), since the content ratio of the phosphorescent pigment in the third phosphorescent ink layer is different from the content ratio of the phosphorescent pigment in the first phosphorescent ink layer and the content ratio of the phosphorescent pigment in the second phosphorescent ink layer, it is easy to cause a difference in the number of stacked layers of the phosphorescent pigment in the third phosphorescent ink layer from the number of stacked layers of the phosphorescent pigment in the first phosphorescent ink layer and the number of stacked layers of the phosphorescent pigment in the second phosphorescent ink layer. For this reason, in the above-described embodiment (D), a difference in luminance or color tone can be caused between the third phosphorescent ink layer and the first phosphorescent ink layer and the second phosphorescent ink layer, and they can be easily visually recognized as different layers. The above-described embodiment (D) is preferably combined with the above-described embodiment (B).

[0049] The first phosphorescent ink layer, the second phosphorescent ink layer, and the third phosphorescent ink layer are preferably transparent or translucent. By being transparent or translucent, the effect of color mixing due to the overlap of each phosphorescent ink layer can be obtained. Further, it becomes possible to visually recognize the color derived from the base material.

[0050] When the cosmetic material 30 is viewed in plan view, the first phosphorescent ink layer, the second phosphorescent ink layer, and the third phosphorescent ink layer are each provided on at least a part of the base material 34.

[0051] When viewed in plan view of the decorative material 30, the first phosphorescent ink layer, the second phosphorescent ink layer, and the third phosphorescent ink layer preferably each consist of an aggregate of a plurality of independent regions. Specifically, in FIG. 4, the first phosphorescent ink layer consists of an aggregate of a plurality of independent regions 36A-1 to 36A-3. The second phosphorescent ink layer consists of an aggregate of a plurality of independent regions 36B-1 to 36B-3. The third phosphorescent ink layer consists of an aggregate of a plurality of independent regions 36C-1 to 36C-3.

[0052] In the region indicated by the reference sign F-1 in FIG. 4, when the decorative material 30 is viewed in plan view, the first phosphorescent ink layer has a region (reference sign Ro-1) that overlaps only with the second phosphorescent ink layer, a region (reference sign Ro-2) that overlaps only with the third phosphorescent ink layer, a region (reference sign Ro-3) that overlaps with both the second phosphorescent ink layer and the third phosphorescent ink layer, and a region (reference sign Ra) that does not overlap with both the second phosphorescent ink layer and the third phosphorescent ink layer. Similarly, the second phosphorescent ink layer has a region (reference sign Ro-1) that overlaps only with the first phosphorescent ink layer, a region (reference sign Ro-4) that overlaps only with the third phosphorescent ink layer, a region (reference sign Ro-3) that overlaps with both the first phosphorescent ink layer and the third phosphorescent ink layer, and a region (reference sign Rb) that does not overlap with both the first phosphorescent ink layer and the third phosphorescent ink layer. The third phosphorescent ink layer has a region (reference sign Ro-2) that overlaps only with the first phosphorescent ink layer, a region (reference sign Ro-4) that overlaps only with the second phosphorescent ink layer, a region (reference sign Ro-3) that overlaps with both the first phosphorescent ink layer and the second phosphorescent ink layer, and a region (reference sign Rc) that does not overlap with both the first phosphorescent ink layer and the second phosphorescent ink layer.

[0053] The region indicated by the reference sign F-2 in FIG. 4 is a region composed of a region (reference sign Ro-2) where the first phosphorescent ink layer (independent region 36A-2) and the third phosphorescent ink layer (independent region 36C-2) overlap, and regions (reference signs Ra, Rc) where the first phosphorescent ink layer and the third phosphorescent ink layer do not overlap with each other. That is, the region F-2 corresponds to the region F in FIG. 1, which is composed of a region where two phosphorescent ink layers overlap and a region where they do not overlap.

[0054] Regions that do not overlap with other phosphorescent ink layers may be provided according to the pattern of the phosphorescent pattern layer, such as the independent regions 36A-3, 36B-2, 36B-3, and 36C-3 in FIG. 4.

[0055] When the decorative material 30 is viewed in plan view, the regions Ra, Rb, and Rc exhibit the colors of the first phosphorescent ink layer, the second phosphorescent ink layer, and the third phosphorescent ink layer, respectively. The regions Ro-1 to Ro-4 where the phosphorescent ink layers overlap exhibit a mixed color of the colors of the respective phosphorescent ink layers. Also, as described above, due to the distribution of the film thickness within the independent regions and the degree of overlap of the phosphorescent ink layers, changes in luminance are likely to occur within the phosphorescent pattern layer. Thus, by increasing the number of phosphorescent ink layers that make up the phosphorescent pattern layer, it is easy to increase the variations in colors and luminance that can be expressed. Also, by providing regions where the combinations of the phosphorescent ink layers that overlap within the plane of the decorative material 30 are different, such as the regions Ro-1 to Ro-4, it is easy to express various patterns. Thus, by increasing the number of phosphorescent ink layers that make up the phosphorescent pattern layer, a decorative material with superior design properties can be obtained.

[0056] Also in the example shown in FIG. 4, it is preferable that at least one of the first phosphorescent ink layer, the second phosphorescent ink layer, and the third phosphorescent ink layer has a partially different film thickness.

[0057] When the third phosphorescent ink layer consists of an aggregate of a plurality of independent regions, it is preferable that when comparing the maximum film thicknesses of the individual independent regions, the maximum film thickness of at least one independent region is different from the maximum film thickness of the other independent regions. Also, when the third phosphorescent ink layer is partially provided as one independent region, it is preferable that the film thickness at any position within the independent region when viewed in plan view is different from the film thickness at other positions within the independent region. Also, when the decorative material is viewed in plan view, the third phosphorescent ink layer consists of an aggregate of a plurality of independent regions, and it is preferable that at least one or more independent regions have a partially different film thickness within the independent region.

[0058] In a region where the first fluorescent ink layer and the third fluorescent ink layer overlap, it is preferable that at least one of the film thickness of the first fluorescent ink layer and the film thickness of the third fluorescent ink layer is partially different. In a region where the second fluorescent ink layer and the third fluorescent ink layer overlap, it is preferable that at least one of the film thickness of the second fluorescent ink layer and the film thickness of the third fluorescent ink layer is partially different.

[0059] FIG. 5 is a schematic cross-sectional view taken along line M-M' of the region indicated by reference numeral F-1 in FIG. 4. FIG. 5 shows an example in which the second fluorescent ink layer and the third fluorescent ink layer are formed in this order after the first fluorescent ink layer is formed, and an example in which the film thickness is partially changed within each independent region. Also in FIG. 5, for the purpose of understanding the present disclosure, the dimension in the thickness direction is enlarged and emphasized as compared with the dimension in the substrate surface direction of the independent region.

[0060] In FIG. 5, in the independent region 36A-1 of the first fluorescent ink layer, the film thickness of the end region is thinner than the film thickness of the central portion. In the overlapping regions Ro-2 and Ro-3, the film thickness of the independent region 36A-1 continuously changes so as to gradually decrease from the center toward the end. The independent region 36B-1 of the second fluorescent ink layer rides on the independent region 36A-1 in the overlapping region Ro-3, and the film thickness of the independent region 36B-1 changes. The independent region 36C-1 of the third fluorescent ink layer rides on the independent region 36A-1 and / or the independent region 36B-1 in the overlapping regions Ro-2, Ro-3, and Ro-4, and the film thickness of the independent region 36C-1 changes.

[0061] In FIGS. 4 and 5, in the non-overlapping regions Ra, Rb, and Rc, as described above, by changing the film thicknesses of the first fluorescent ink layer, the second fluorescent ink layer, and the third fluorescent ink layer, it is possible to easily visually recognize changes in color shading and luminance. Specifically, at locations where the film thickness is thick, the degree of multiple reflection by the fluorescent pigment increases, resulting in a darker color and a stronger luminance that is easily visible. On the other hand, at locations where the film thickness is thin, the color appears lighter and the luminance appears weaker and is easily visible.

[0062] In FIGS. 4 and 5, within the overlapping regions Ro-1 to Ro-4, the color mixing and luminance correspond to the film thickness ratios of the respective fluorescent ink layers. Furthermore, in regions Ro-1 to Ro-4, the shading and luminance can be expressed by the total film thickness of the fluorescent ink layers. Therefore, also with the above configuration, by partially varying the film thicknesses of the respective fluorescent ink layers, it is possible to easily express a natural gradation in color shading, color mixing degree, and luminance intensity. For this reason, it becomes possible to express colors with even more variety, and it is easy to express various patterns. As a result, it is possible to obtain a decorative material having a design with particularly excellent visual effects.

[0063] The decorative material of the present disclosure can also express a design with excellent design properties or a design closer to the actual material by combining the pattern of the fluorescent pattern layer described above, the pattern by color, and further the color derived from the base of the fluorescent pattern layer. Preferable examples of patterns that can be expressed by the decorative material of the present disclosure include patterns on the surface of a metal plate having a metal oxide film on the surface, such as an iron sheet pattern, a rust pattern, or a baked pattern, and further, a metal plate surface pattern having a gloss due to interference, such as an oil film pattern on the surface of a metal plate. Also, as patterns that can be expressed by the decorative material of the present disclosure, there are a marble pattern (for example, a travertine marble pattern), a stone grain pattern imitating the surface of a rock such as the split surface of a granite slab, a wood grain pattern (particularly a wood grain pattern having a shiny portion), a fabric pattern (particularly a fabric pattern imitating a silk fabric containing interference gloss), a pattern expressing the texture of leather (leather texture), a tile pasted pattern, a brick stacked pattern, a matte pattern, a sandblasted pattern, a geometric pattern, a beetle wing pattern, and the like.

[0064] Next, an embodiment of the laminated structure of the cosmetic material of the present disclosure will be described. FIG. 6 is a schematic cross-sectional view of a cosmetic material according to an embodiment of the present disclosure. FIG. 6 is a schematic cross-sectional view when cut in the Z-axis direction in FIG. 1, for example. In the cosmetic material 100 of FIG. 6, a primer layer 104, a base coat layer 106, a glitter pattern layer 108, a protective layer 110, a raised layer 120, and a surface coat layer 112 are provided in this order on a base material 102. In the present disclosure, a configuration in which both the raised layer 120 and the surface coat layer 112 are provided may be adopted, or a configuration in which either one of them is provided may be adopted. For example, instead of the configuration of FIG. 6, a layer configuration may be adopted in which the raised layer is omitted and the surface coat layer 112 is directly formed on the protective layer 110. Regardless of the presence or absence of the raised layer, the protective layer may be provided or may be omitted. Hereinafter, each layer will be described in detail.

[0065] <Base material> The base material 102 is not particularly limited as long as it is commonly used as a cosmetic material. For example, a resin base material, a metal base material, a ceramic base material, a fibrous base material, a woody base material, etc. can be appropriately selected according to the application. Each of the above base materials may be used alone, or may be a laminate by any combination. When the base material 102 is a laminate, a configuration in which an adhesive layer is further provided between the respective layers of the laminate may be adopted.

[0066] Examples of the resin base material include those made of various synthetic resins. Examples of the synthetic resin include olefin resins such as polyethylene resin, polypropylene resin, and polymethylpentene resin; vinyl resins such as polyvinyl chloride resin, polyvinylidene chloride resin, polyvinyl alcohol resin, vinyl chloride-vinyl acetate copolymer resin, ethylene-vinyl acetate copolymer resin, and ethylene-vinyl alcohol copolymer resin; polyester resins such as polyethylene terephthalate resin, polybutylene terephthalate resin, and ethylene naphthalate-isophthalate copolymer resin; acrylic resins such as polymethyl methacrylate resin, polyethyl methacrylate resin, and polybutyl acrylate resin; polyamide resins typified by nylon 6 or nylon 66; cellulose resins such as triacetate cellulose resin and cellophane; polystyrene resin, polycarbonate resin, polyarylate resin, and polyimide resin, etc.

[0067] Examples of the metal base material include pure metals composed of a single metal element such as aluminum, iron, copper, and titanium, and alloys such as carbon steel, stainless steel, duralumin, brass, and bronze containing one or more of these metals. In addition, those obtained by applying plating or the like to the surface of these metals as the base material can also be used. Since the metal base material has excellent heat resistance, it is preferable because it has resistance to deformation and the like during the heat treatment at high temperature (drying after the formation of the base coat layer and the final baking treatment) in the manufacturing method described later. Since the metal base material has the above-described characteristics, it can easily maintain the shape of the raised layer. Further, by using the metal base material, the reflection on the surface of the metal base material can be superimposed on the reflection of the glitter pigment, so that the effect of the glitter pigment can be further enhanced.

[0068] Examples of the ceramic base material include ceramic building materials such as gypsum board, calcium silicate board, and wood chip cement board, and ceramics such as ceramics, glass, enamel, and fired tiles. Since the ceramic base material also has excellent heat resistance, it is preferable because it has resistance to deformation and the like during the heat treatment at high temperature in the manufacturing method described later.

[0069] As the fibrous substrate, for example, paper substrates such as tissue paper, kraft paper, titanium paper, linter paper, cardboard, and base paper for gypsum board can be used. In order to increase the inter-fiber strength of the paper substrate or the interlayer strength between other layers and the paper substrate, and to prevent keba standing, further, resins such as acrylic resin, styrene-butadiene rubber, melamine resin, and urethane resin may be added (resin impregnation after papermaking or internal filling during papermaking). Examples of the paper substrate added with resin include paper with enhanced paper strength and resin-impregnated paper. In addition, as the fibrous substrate, a vinyl wallpaper base fabric with a vinyl chloride resin layer provided on the surface of the paper substrate can also be used.

[0070] In addition, as the fibrous substrate, although different from the above-mentioned paper substrates, woven fabrics and non-woven fabrics of various fibers having an appearance and properties similar to paper can also be mentioned. Examples of various fibers include inorganic fibers such as glass fiber, asbestos fiber, potassium titanate fiber, alumina fiber, silica fiber, and carbon fiber. In addition, examples of various fibers include synthetic resin fibers such as polyester fiber, acrylic fiber, and vinylon fiber. From the viewpoint of the shaping suitability of the uneven pattern, these papers are preferably laminated and used with a plastic substrate having excellent shaping suitability.

[0071] Examples of the woody substrate include veneers, plywood, laminated wood, particle board, and medium density fiberboard (MDF) of woods such as cedar, cypress, pine, oak, zelkova, maple, lauan, and teak.

[0072] The thickness of the substrate 102 is not particularly limited and can be appropriately set according to the use, required specifications, etc. For example, the thickness of the substrate 2 is preferably 0.2 mm or more and 5 mm or less, and more preferably 0.4 mm or more and 3 mm or less.

[0073] <Primer layer> The primer layer 104 is provided between the base material 102 and the luminescent pattern layer 108 as required. When the decorative material has a base coat layer 106, it is preferable to provide the primer layer 104 between the base material 102 and the base coat layer 106. The primer layer 104 serves to ensure good adhesion between the base material 102 and the base coat layer 106, or between the base material 102 and the luminescent pattern layer 108.

[0074] For the formation of the primer layer 104, for example, ink containing a material constituting the primer layer (primer layer ink) is used. Examples of the material constituting the primer layer include resins. The type of resin can be selected in consideration of the material of the layer in contact with the primer layer (for example, the material of the base material 102 and the material of the resin serving as the binder of the base coat layer 106 described later). The primer layer ink may appropriately contain a solvent.

[0075] Examples of the resin include urethane resins, acrylic polyol resins, acrylic resins, ester resins, amide resins, butyral resins, styrene resins, urethane-acrylic copolymers, polycarbonate-based urethane-acrylic copolymers (urethane-acrylic copolymers derived from polymers having carbonate bonds in the polymer main chain and having two or more hydroxyl groups at the terminals and side chains (polycarbonate polyols)), vinyl chloride-vinyl acetate copolymer resins, vinyl chloride-vinyl acetate-acrylic copolymer resins, chlorinated propylene resins, nitrocellulose resins (nitrocellulose), cellulose acetate resins, fluorine resins, etc. These resins can be used alone or in combination of multiple types.

[0076] In addition to one-component curing types, for example, various types of resins such as two-component curing types accompanied by curing agents such as isocyanate compounds such as tolylene diisocyanate (TDI), diphenylmethane diisocyanate (MDI), hexamethylene diisocyanate (HDI), isophorone diisocyanate (IPID), xylylene diisocyanate (XDI) can be used.

[0077] From the perspective of improving weather resistance, the primer layer 104 preferably contains weathering agents such as ultraviolet absorbers and light stabilizers.

[0078] From the perspective of the effect of improving interlayer adhesion, etc., the thickness of the primer layer 104 is preferably 1 μm or more, more preferably 2 μm or more, and even more preferably 3 μm or more. Further, as the upper limit of the thickness of the primer layer 104, 10 μm or less is preferable, 7 μm or less is more preferable, and 5 μm or less is even more preferable.

[0079] <Base coat layer> The base coat layer 106 is a layer provided between the base material 102 and the iridescent pattern layer 108 as needed. The base coat layer 106 is preferably provided on the entire surface of the base material.

[0080] In the present disclosure, the base coat layer 106 may be colored or colorless. By coloring the base coat layer 106 in an arbitrary color, it is possible to impart the intended color as the background of the iridescent pattern layer 108. The base coat layer 106 is preferably formed as an opaque layer for coloring to conceal the base material 102 when viewed by the viewer and to impart the intended color. For example, when a dark opaque layer such as black is formed as the base coat layer, designs such as rust and burnt feeling can be expressed. On the other hand, by making the base coat layer 106 a colorless layer (transparent layer), it is possible to make use of the appearance such as the pattern, color, and gloss of the base material 102. Further, when a transparent layer is formed as the base coat layer, designs such as an oil film can be expressed. As described above, by making the base coat layer function as the basis of the color of the decorative material, the design property of the decorative material can be enhanced.

[0081] For the formation of the base coat layer 106, for example, ink containing a material constituting the base coat layer (ink for the base coat layer) is used. Examples of the material constituting the base coat layer include resins. The ink for the base coat layer may appropriately contain a solvent. The resin used for forming the base coat layer 106 is not particularly limited. For example, thermoplastic resins such as fluororesin, (meth)acrylic resin, urethane resin, polyester resin, polyamide resin, (meth)acrylic acid ester-olefin copolymer, vinyl chloride-vinyl acetate copolymer, ethylene-vinyl acetate copolymer (EVA resin), ionomer resin, olefin-α olefin copolymer, etc.; curable resins such as fluororesin, epoxy resin, phenol resin, urea resin, polyester resin, melamine resin, alkyd resin, polyimide resin, silicone resin, hydroxyl group functional acrylic resin, carboxyl group functional acrylic resin, amide functional copolymer, urethane resin, etc. Here, the curable resins include thermosetting resins, radiation curable resins, two-component curable resins, etc.

[0082] When the base coat layer 106 is provided as an opaque layer (concealing layer) and a translucent layer, the base coat layer 106 preferably contains a colorant such as a pigment together with the above-described resin. The colorant blended in the base coat layer 106 is not particularly limited. For example, inorganic pigments such as carbon black, iron black, titanium white, antimony white, yellow titanium yellow, cadmium red, ultramarine blue, cobalt blue, etc.; organic pigments or dyes such as quinacridone red, isoindolinone yellow, phthalocyanine blue, etc. These colorants may be used alone or in combination of two or more. In order to make the pattern by the glitter pattern layer 108 stand out easily, it is preferable to blend a dark colorant in the base coat layer 106. Examples of the dark colorant include carbon black and iron oxide.

[0083] In addition to the above components, various additives can be incorporated into the base coat layer 106 according to the desired physical properties. Examples of the additives include weather resistance improvers such as ultraviolet absorbers and light stabilizers, abrasion resistance improvers, polymerization inhibitors, infrared absorbers, defoamers, fillers, and the like. Further, when a curable resin is used for forming the base coat layer 106, a curing agent may be included. These additives can be appropriately selected from commonly used ones and used.

[0084] The thickness of the base coat layer 106 is not particularly limited and can be appropriately set according to the use, required specifications, and the like. For example, the thickness of the base coat layer 4 is preferably 5 μm to 40 μm, and more preferably 10 μm to 30 μm.

[0085] <Glossy pattern layer> The glossy pattern layer 108 is provided on the surface side of the base material 102 and is a layer that imparts design properties to the decorative material. As described above, the glossy pattern layer 108 is composed of a plurality of glossy ink layers.

[0086] For forming the glossy ink layer, for example, an ink containing a material constituting the glossy ink layer (ink for glossy ink layer) is used. Examples of the material constituting the glossy ink layer include a binder resin and a glossy pigment. The ink for the glossy ink layer may appropriately contain a solvent, a matting agent, and the like. When the glossy ink layer contains a matting agent, in order to suppress a decrease in the visual effect of the glossy pigment, the particle size of the matting agent is preferably less than 5 μm, more preferably 4 μm or less, and even more preferably 3 μm or less.

[0087] Examples of the binder resin include resins such as urethane resin, acrylic polyol resin, acrylic resin, polyester resin, alkyd resin, amide resin, butyral resin, styrene resin, urethane-acrylic copolymer, vinyl chloride-vinyl acetate copolymer, vinyl chloride-vinyl acetate-acrylic copolymer, nitrocellulose (nitrated cotton), cellulose acetate, and fluororesin. Further, a curable resin such as a two-component curable urethane resin having a polyol as a main component and an isocyanate as a curing agent may be used. These can be used alone or in combination of two or more. For example, as described in the manufacturing method to be described later, in the case of baking after forming the bright pattern layer 108 in the decorative material having a metal plate as a base material, considering the processability, it is preferable to select a fluorine-based resin, an acrylic-based resin, or a polyester-based resin as the binder resin of the bright pattern layer 108.

[0088] Typical examples of the bright pigment used in the bright pattern layer 108 include pearl pigments and metallic pigments. Examples of the pearl pigment include interference pearl pigments (polarized pearl pigments); colored pearl pigments; white pearl pigments; scaly foil pieces made of shells of shells such as mother-of-pearl, basic lead carbonate, bismuth oxychloride, etc. The interference pearl pigment is formed by coating the surface of a matrix of scaly foil pieces such as mica, aluminum, and glass with a coating layer, the coating layer is a colorless high refractive index material such as titanium dioxide, and the thickness of the coating layer is more than 0.15 μm. Due to this thickness, the reflected light and transmitted light change, generating various interference colors. The colored pearl pigment is a colored one, having a coating layer on the matrix surface made of a colored high refractive index material such as ferric oxide, or having the periphery of the white pearl pigment further coated with a colored high refractive index material such as ferric oxide or other colored pigments, or having a pigment or other colorant added to the coating layer. The white pearl pigment is obtained by covering the matrix surface of scaly foil pieces such as mica, aluminum, and glass with a coating layer made of a colorless high refractive index material such as titanium dioxide, and the thickness of the coating layer is relatively small, about 0.1 to 0.15 μm. Since it reflects almost all wavelengths of light, it appears white or silver. Examples of the metallic pigment include those composed of scaly foil pieces of metals such as aluminum, brass, tin, gold, silver, and copper.

[0089] The content of the pearlescent pigment in each pearlescent ink layer is preferably 1 to 40 parts by mass, more preferably 3 to 30 parts by mass, and even more preferably 5 to 15 parts by mass with respect to 100 parts by mass of the binder resin. The cosmetic material of the present disclosure may contain a pearlescent pigment in a layer other than the pearlescent ink layer as long as it does not inhibit the effects of the cosmetic material. However, the content of the pearlescent pigment in the layer other than the pearlescent ink layer is preferably small. The content of the pearlescent pigment in the layer other than the pearlescent ink layer is preferably 4% by mass or less, more preferably 2% by mass or less, and most preferably 0% by mass with respect to the total solid content of the layer.

[0090] The pearlescent pigment contained in each pearlescent ink layer may be used alone or in combination of two or more. When combining two or more kinds, it may be two or more selected from the above pearl pigments, two or more selected from the above metallic pigments, or a combination of one or more selected from the above pearl pigments and one or more selected from the above metallic pigments. Also, each pearlescent ink layer may contain a colorant other than the pearlescent pigment (for example, the colorants listed in the base coat layer) as long as it does not inhibit the visual effect of the pearlescent pigment.

[0091] In this specification, "the first fluorescent pigment and the second fluorescent pigment are different" between the first fluorescent ink layer and the second fluorescent ink layer means that at least one of the reflection characteristics selected from the visual reflectance Y value, spectral reflectance, L* value, a* value, and b* value is different between the first fluorescent pigment and the second fluorescent pigment. Similarly, in this specification, "the third fluorescent pigment is different from the first fluorescent pigment and the second fluorescent pigment" means that at least one of the reflection characteristics selected from the visual reflectance Y value, spectral reflectance, L* value, a* value, and b* value is different between the third fluorescent pigment and the first fluorescent pigment and the second fluorescent pigment. In this specification, the L* value, a* value, and b* value mean the L* value, a* value, and b* value of the L*a*b* color system. The L*a*b* color system is standardized by the International Commission on Illumination (CIE) in 1976 and is based on the L*a*b* color system, and is adopted in JIS Z8781-4:2013. Examples of the first fluorescent pigment and the second fluorescent pigment being different include the combinations of the following (1) to (12). Of course, the combinations are not limited to the following examples, and combinations other than the following are also possible. (1) A combination of a white pearl pigment and an interference pearl pigment. (2) A combination of a white pearl pigment and a colored pearl pigment. (3) A combination of an interference pearl pigment and a colored pearl pigment.

In the present disclosure, from the viewpoint of taking advantage of color mixing, the superposition effect of brightness when the gloss ink layers overlap, and the change in hue when the light incident angle on the decorative material or the viewing angle of the observer is changed, it is preferable to use a pearl pigment. In particular, since it is possible to express a design with an appearance utilizing an interference color, it is preferable to use an interference pearl pigment. By using a pearl pigment, particularly an interference pearl pigment, it is possible to easily reproduce patterns on the surface of a metal plate having a metal oxide film on the surface, such as an iron skin pattern, a rust pattern, or a baked pattern.

[0092] In this specification, "the content ratio of the bright pigment in the first bright ink layer is different from the content ratio of the bright pigment in the second bright ink layer" means that the content of the bright pigment with respect to 100 parts by mass of the binder resin in the first bright ink layer (in this specification, may be referred to as "the first content"), and the content of the bright pigment with respect to 100 parts by mass of the binder resin in the second bright ink layer (in this specification, may be referred to as "the second content") are different. Similarly, in this specification, "the content ratio of the bright pigment in the third bright ink layer is different from the content ratio of the bright pigment in the first bright ink layer and the content ratio of the bright pigment in the second bright ink layer" means that the content of the bright pigment with respect to 100 parts by mass of the binder resin in the third bright ink layer (in this specification, may be referred to as "the third content") is different from the first content and the second content. The absolute value of the difference between the first content and the second content is preferably 1 part by mass or more, more preferably 3 parts by mass or more, and even more preferably 5 parts by mass or more. The upper limit of the absolute value of the difference between the first content and the second content is not particularly limited, but is preferably 15 parts by mass or less, more preferably 12 parts by mass or less, and even more preferably 10 parts by mass or less. The absolute value of the difference between the third content and the first content and the second content is preferably 1 part by mass or more, more preferably 3 parts by mass or more, and even more preferably 5 parts by mass or more, respectively. The upper limit of the absolute value of the difference between the third content and the first content and the second content is not particularly limited, but is preferably 15 parts by mass or less, more preferably 12 parts by mass or less, and even more preferably 10 parts by mass or less, respectively.

[0093] The luminescent pigment preferably has an average length of 5 to 70 μm, more preferably 10 to 40 μm. The average length of the luminescent pigment is determined as the average value of the lengths of any 20 particles (luminescent pigments) observed with an optical microscope or an electron microscope from a direction perpendicular to the substrate surface of the luminescent ink layer formed on the substrate. The length of one luminescent pigment means the maximum length in the in-plane direction of the substrate of one luminescent pigment.

[0094] Further, the average thickness of the luminescent pigment is preferably 0.01 to 1 μm, more preferably 0.02 to 0.7 μm, and even more preferably 0.05 to 0.5 μm. The average thickness of the luminescent pigment is determined as the average value of the thicknesses of any 20 particles (luminescent pigments) observed with an optical microscope or an electron microscope of the cross section of the luminescent ink layer formed on the substrate. The thickness of one luminescent pigment means the average of t1 to t5 obtained by dividing the cross-sectional image of one luminescent pigment into five regions with equal lengths in the length direction and measuring the thicknesses (t1, t2, t3, t4, t5) at the central parts of each region. The luminescent pigment preferably has an aspect ratio (average length / average thickness) of 10 or more and 180 or less between the average length and the average thickness.

[0095] From the viewpoint of improving weather resistance, the luminescent pattern layer 108 may contain weathering agents such as ultraviolet absorbers and light stabilizers.

[0096] <Raised layer> The raised layer 120 is provided, if necessary, on at least a part of the luminous pattern layer 108. The raised layer is a layer that imparts a tactile and visual effect (gloss-matte effect) to the decorative material. The combination of the raised layer and the luminous pattern layer can easily reproduce the iron sheet pattern and the rust pattern. By combining the raised layer and the luminous pattern layer, and by including a dark colorant in the base coat layer, it is possible to more easily reproduce the iron sheet pattern and the rust pattern. Furthermore, by using a metal substrate as the base material, it is possible to more easily reproduce the iron sheet pattern and the rust pattern. Also, the appearance of the luminous pattern layer can be changed between the part with the raised layer and the part without the raised layer. For this reason, it is preferable to provide the raised layer on a part of the luminous pattern layer. By forming the raised layer on a part of the luminous pattern layer, for example, in the plane of the decorative material, a rusty-looking area and a non-rusty-looking area can be formed, and the visual effect can be further enhanced (the part where the raised layer is formed is likely to look rusty because the gloss decreases). Forming the raised layer on a part of the luminous pattern layer means that when the decorative material is viewed in plan view, the raised layer viewed in plan view overlaps a part of the luminous pattern layer viewed in plan view. Depending on the specifications required for the decorative material, the raised layer 120 may not be provided. The raised layer 120 may be provided over the entire surface of the base material 102 or provided in a predetermined pattern in a part when the decorative material 100 is viewed from the surface side.

[0097] As schematically shown in FIG. 6, the raised layer 120 is preferably formed from an aggregate of a plurality of convex portion regions 122. Each of the convex portion regions 122 includes a plurality of particles 124, and the particles 124 are covered with a binder resin 126. Since the coating with the resin is thin, the surface of the convex portion region 122 has an uneven shape roughly following the particle surface. The raised layer 120 can easily impart an excellent tactile and gloss-matte effect due to the unevenness (relatively large unevenness) caused by the plurality of convex portion regions 122 and the unevenness (relatively small unevenness) caused by the particles 124 on the surface of each convex portion region 122.

[0098] For forming the raised layer 120, for example, ink (ink for the raised layer) containing a material constituting the raised layer is used. Examples of the material constituting the raised layer include particles and binder resin. The ink for the raised layer may appropriately contain a solvent. Examples of the binder resin of the raised layer 120 include urethane resins, acrylic polyol resins, acrylic resins, ester resins, amide resins, butyral resins, styrene resins, urethane-acrylic copolymers, polycarbonate-based urethane-acrylic copolymers (urethane-acrylic copolymers derived from polymers having carbonate bonds in the polymer main chain and two or more hydroxyl groups at the terminals and side chains (polycarbonate polyols)), vinyl chloride-vinyl acetate copolymers, vinyl chloride-vinyl acetate-acrylic copolymers, chlorinated propylene resins, nitrocellulose resins (nitrocellulose), cellulose acetate resins, fluorine resins, etc. These resins can be used alone or in combination of two or more kinds.

[0099] Examples of the particles contained in the raised layer 120 include organic fillers composed of resin particles such as acrylic resins, urethane resins, nylon resins, polypropylene resins, and urea resins. From the viewpoint of good heat resistance and easy maintenance of the height after the baking process, acrylic resin is particularly preferred. Considering the touch feeling and the durability of the raised layer (resistance to particle detachment), the particle size of the particles 124 is preferably 5 μm to 60 μm. In this specification, the particle size of various particles is the 50% particle size (d50: median diameter) when the particle size distribution measured by the dynamic light scattering method is represented by the volume cumulative distribution.

[0100] Also, considering the touch feeling, the content of the particles is preferably 10 parts by mass or more, more preferably 20 parts by mass or more, and still more preferably 30 parts by mass or more with respect to 100 parts by mass of the binder resin constituting the convex portion region 122. On the other hand, from the viewpoint of surely binding the particles with the binder resin to suppress dropout and making the fluidity of the resin composition good to facilitate the forming process, the content of the particles is preferably 50 parts by mass or less, more preferably 40 parts by mass or less, and still more preferably 30 parts by mass or less with respect to 100 parts by mass of the binder resin.

[0101] The raised layer 120 may further contain an inorganic filler. Examples of the inorganic filler include particles such as silica, clay, heavy calcium carbonate, light calcium carbonate, precipitated barium sulfate, calcium silicate, and synthetic silicate. The size of the inorganic filler is preferably 1 μm to 20 μm, more preferably 3 μm to 10 μm, and still more preferably 3 μm to 7 μm. The content of the inorganic filler is preferably 5 parts by mass to 40 parts by mass, more preferably 10 parts by mass to 30 parts by mass, and still more preferably 15 parts by mass to 25 parts by mass with respect to 100 parts by mass of the binder resin. By including the inorganic filler in this way, the gloss difference between the region where the raised layer 120 is formed and the region where there is no raised layer 120 can be increased, and it is easy to impart a high-class design to the decorative material.

[0102] The raised layer 120 may further contain glitter particles. Examples of the glitter particles include metallic pigments, pearl pigments, glass flakes, phosphorescent pigments, gold powder, hologram glitter, and combinations thereof.

[0103] From the viewpoint of improving weather resistance, the raised layer 120 preferably contains a weathering agent such as an ultraviolet absorber and a light stabilizer.

[0104] The average thickness of the raised layer 120 is not particularly limited and may be appropriately set according to the touch feeling and visual effect required for the decorative material. The thickness of the raised layer 120 is preferably 5 μm to 60 μm, more preferably 15 μm to 45 μm, and still more preferably 25 μm to 35 μm.

[0105] <Protective layer> The protective layer 110 is formed on the glitter pattern layer 108 as required. When the decorative material has the raised layer 120, the protective layer 110 is preferably formed between the glitter pattern layer 108 and the raised layer 120. The protective layer serves, for example, to protect the glitter pattern layer 108. In addition, the protective layer 110 serves to improve the adhesion between the glitter pattern layer 108 and the raised layer 120. The protective layer 110 may be provided over the entire surface of the base material 102 or on a part thereof when viewed from the surface side.

[0106] For forming the protective layer 110, for example, ink containing a material constituting the protective layer (ink for the protective layer) is used. Examples of the material constituting the protective layer include resins. The ink for the protective layer may appropriately contain a solvent.

[0107] Examples of the resin preferably include urethane resins, acrylic polyol resins, acrylic resins, polyester resins, alkyd resins, amide resins, butyral resins, styrene resins, urethane-acrylic copolymers, vinyl chloride-vinyl acetate copolymers, vinyl chloride-vinyl acetate-acrylic copolymers, nitrocellulose, cellulose acetate, fluorine-based resins, and the like. Also, for example, a curable resin such as a two-component curable urethane resin having a polyol as a main agent and an isocyanate as a curing agent may be used. These can be used alone or in combination of a plurality of types.

[0108] For the purpose of improving the visual effect (gloss-matte effect) due to the difference in gloss between the protective layer 110 and the raised layer 120, the protective layer 110 is preferably glossier than the raised layer 120. The protective layer 110 preferably contains a matting agent as required. Examples of the matting agent include inorganic fillers composed of particles such as silica, clay, heavy calcium carbonate, light calcium carbonate, precipitated barium sulfate, calcium silicate, synthetic silicate, and fine silica powder. The volume average particle size of the matting agent is preferably 1 to 20 μm, more preferably 3 to 10 μm, and still more preferably 5 to 7 μm.

[0109] In addition, the content of the matting agent with respect to 100 parts by mass of the binder resin in the protective layer 110 is preferably 5 parts by mass or more, more preferably 10 parts by mass or more, still more preferably 20 parts by mass or more, and the upper limit is usually 100 parts by mass or less, preferably 80 parts by mass or less, more preferably 50 parts by mass or less, and still more preferably 30 parts by mass or less. When the content of the matting agent is within the above range, an excellent visual effect (gloss-matte effect) can be obtained.

[0110] From the viewpoint of improving weather resistance, the protective layer 110 may contain weathering agents such as ultraviolet absorbers and light stabilizers.

[0111] The thickness of the protective layer 110 may be appropriately selected according to the desired pattern. The protective layer 110 is preferably 2 μm or more, more preferably 4 μm or more, and still more preferably 6 μm or more. The upper limit of the thickness is preferably 20 μm or less, more preferably 15 μm or less, and still more preferably 10 μm or less.

[0112] <Surface coating layer> On the outermost surface of the decorative material 100, a surface coating layer 112 may be formed as necessary to improve durability such as weather resistance, scratch resistance, abrasion resistance, and stain resistance. When the desired durability can be exhibited even in the form where the raised layer 120 is exposed on the outermost surface, the surface coating layer can be omitted.

[0113] For the formation of the surface coating layer 112, for example, ink containing a material constituting the surface coating layer (ink for surface coating layer) is used. Examples of the material constituting the surface coating layer include resins. The ink for surface coating layer may appropriately contain a solvent. The resin used for forming the surface coating layer 112 is not particularly limited. For example, thermoplastic resins such as (meth)acrylic resin, polyurethane resin, polyester resin, polyamide resin, (meth)acrylic acid ester-olefin copolymer, vinyl chloride-vinyl acetate copolymer, ethylene-vinyl acetate copolymer (EVA resin), ionomer resin, olefin-α olefin copolymer resin, etc.; epoxy resin, phenol resin, urea resin, unsaturated polyester resin, melamine resin, alkyd resin, polyimide resin, silicone resin, hydroxyl group-functional acrylic resin, carboxyl group-functional acrylic resin, amide-functional copolymer, urethane resin, fluororesin, etc. These resins may be used alone or in combination of two or more.

[0114] Various additives can be blended into the surface coating layer 112 according to the desired physical properties. Examples of the additives include weather resistance improvers such as ultraviolet absorbers (benzotriazole-based ultraviolet absorbers, triazine-based ultraviolet absorbers, etc.), light stabilizers (hindered amine-based radical scavengers, etc.), wear resistance improvers (particles such as silica, alumina, kaolinite, etc.), polymerization inhibitors, infrared absorbers, defoamers, fillers, etc.

[0115] The surface coating layer 112 may or may not contain a matting agent according to the required visual effect. When containing a matting agent, a decorative material with a matte feeling can be obtained. When not containing a matting agent, the color development by the fluorescent pigment in the fluorescent pattern layer can be enhanced. Also, even when providing a raised layer, a matting agent can be blended into the surface coating layer 112 as needed. Examples of the matting agent include inorganic fillers composed of particles such as silica, clay, heavy calcium carbonate, light calcium carbonate, precipitated barium sulfate, calcium silicate, synthetic silicate, and fine silica powder. The particle size of the matting agent is preferably 1 to 20 μm, more preferably 3 to 10 μm, and still more preferably 5 to 7 μm. The particle size of the matting agent in the surface coating layer is preferably smaller than the particle size of the particles in the raised layer.

[0116] The thickness of the surface coating layer 112 is not particularly limited and can be appropriately set according to the use, required specifications, etc. The surface coating layer 112 is preferably 2 μm or more, more preferably 5 μm or more, and still more preferably 10 μm or more. Also, the upper limit of the thickness is preferably 30 μm or less, more preferably 25 μm or less, and still more preferably 20 μm or less.

[0117] The decorative material of the present disclosure can exemplify the following laminated configurations. The symbol " / " means the boundary of each layer.

[0118] [Method for manufacturing a decorative material] The method for manufacturing the decorative material of the present disclosure is a method for manufacturing a decorative material including a step of forming a glitter pattern layer on a substrate, The glitter pattern layer has at least a first glitter ink layer and a second glitter ink layer, The first glitter ink layer and the second glitter ink layer satisfy the following relationship (A) or (B), When the decorative material is viewed in plan, each of the glitter ink layers is provided on at least a part of the substrate, When the decorative material is viewed in plan, the first glitter ink layer has a region overlapping with the second glitter ink layer and a region not overlapping with the second glitter ink layer, and the second glitter ink layer has a region overlapping with the first glitter ink layer and a region not overlapping with the first glitter ink layer. (A) The first fluorescent ink layer contains a first fluorescent pigment, and the second fluorescent ink layer contains a second fluorescent pigment different from the first fluorescent pigment. (B) The first fluorescent ink layer and the second fluorescent ink layer contain fluorescent pigments, and the content ratio of the fluorescent pigment in the first fluorescent ink layer is different from the content ratio of the fluorescent pigment in the second fluorescent ink layer.

[0119] In the method for manufacturing the above cosmetic material, the fluorescent pattern layer can be formed, for example, by the following methods (i) and (ii).

(ii) A step of transferring the transfer layer of a transfer sheet having a transfer layer containing the fluorescent pattern layer onto the base material.

[0120] In the method of (i) above, as means for applying and drying the ink for the first fluorescent ink layer and the ink for the second fluorescent ink layer, general-purpose means can be adopted. Examples of general-purpose coating means include gravure printing, offset printing, flexographic printing, letterpress printing, screen printing, inkjet printing, and the like. When the cosmetic material has a layer other than the fluorescent pattern layer, the layer other than the fluorescent pattern layer can be formed, for example, by applying and drying an ink containing the material constituting each layer at a predetermined location such as on the base material or on the fluorescent pattern layer.

[0121] In the method of (ii) above, the fluorescent pattern layer contained in the transfer layer can be formed, for example, by a step of applying and drying an ink for the first fluorescent ink layer on the release layer, and a step of applying and drying an ink for the second fluorescent ink layer on the release layer. When the transfer layer has a layer other than the fluorescent pattern layer, the layer other than the fluorescent pattern layer can be formed, for example, by applying and drying an ink containing the material constituting each layer at a predetermined location such as on the release layer or on the fluorescent pattern layer. In the method of (ii) above, the transfer sheet is detachable at the interface between the release layer and the transfer layer. The transfer sheet preferably has a release layer and a transfer layer on a support and is detachable at the interface between the release layer and the transfer layer. In the method of (ii) above, when the surface of the decorative material is formed into an uneven shape, it is preferable that the surface shape of the release layer is also an uneven shape. By making the surface shape of the release layer an uneven shape, a shape in which the surface shape of the release layer is inverted can be imparted as the surface shape of the decorative material.

[0122] As described above, each layer other than the base material of the decorative material of the present disclosure can be formed by, for example, general-purpose coating means. For example, for the formation of the base coat layer, flow coater coating, roll coating, reverse coating, air spray painting, electrostatic painting, powder painting, etc. can be applied. For the formation of the glitter pattern layer (glitter ink layer), protective layer, and surface coat layer, on-demand printing typified by gravure printing, offset printing, flexographic printing, letterpress printing, screen printing, inkjet printing, etc. can be applied. Also, for the formation of the raised layer, it is preferable to apply gravure printing. When a metal base material is used as the base material, after forming the outermost layer (raised layer or surface coat layer), a baking process at a high temperature (for example, the base material reaching temperature of 150 to 270 °C) may be performed.

[0123] [Laminate] The laminate of the present embodiment includes an adherend and the decorative material of the present disclosure laminated on the adherend. It is preferable that the adherend and the decorative material are fixed with an adhesive layer, nails, etc. The adherend can be appropriately selected according to the use of the laminate. For example, examples of the adherend include metal members, wooden members, ceramic members, and resin members.

[0124] [Uses of Decorative Material and Laminate] The decorative material and laminate of the present disclosure can be used, for example, as a surface decorative board for interior members or exterior members. Examples of interior members include surface materials of interior building members such as walls, floors, and ceilings; surface materials of interior fixtures such as partitions, doors, window frames, handrails, moldings, and unit bathrooms; interior materials of vehicles such as automobiles and trains; and surface materials of home appliances. Examples of exterior members include surface materials of exterior building members such as roofs, walls, floors, veranda blinds, eaves, and ceilings; surface materials of exterior fixtures such as entrance doors, doors, window frames, handrails, moldings, and malls; exterior materials of vehicles such as automobiles and trains; and the like.

[0125] Next, the present disclosure will be described in more detail with reference to examples, but the present disclosure is not limited to these examples in any way.

[0126] [Example 1] An ink for primer layer with the following formulation was roll-coated on the entire surface of a steel plate (size: 800 mm × 2000 mm, thickness: 0.6 mm) so that the film thickness after drying would be 2 μm. Then, it was dried at 230°C (substrate reaching temperature) to form a primer layer. <Ink for primer layer> · Thermosetting polyester resin · Solvents (cyclohexanone, propylene glycol monomethyl ether acetate, swazol, naphthalene) · Solid content: 74%

[0127] An ink for base coat layer with the following formulation was curtain flow coated on the entire surface of the primer layer so that the film thickness after drying would be 22 μm. Then, it was dried at 180°C (substrate reaching temperature) to form a base coat layer. <Ink for base coat layer> · Thermosetting polyester resin · Colorants (carbon black, titanium oxide, iron oxide, and yellow iron oxide): 25 parts by mass with respect to 100 parts by mass of the resin · Solvents (xylene, cyclohexanone)

[0128] On the base coat layer, the first to third fluorescent ink layers were laminated (three-layer structure) to form a fluorescent pattern layer. Specifically, using a plate engraved with a pattern such that the cross-section of each fluorescent ink layer has the shape shown in Fig. 5, a fluorescent ink layer composed of an aggregate of a plurality of independent regions was formed by gravure offset printing. The printing was performed in the order of the first fluorescent ink layer, the second fluorescent ink layer, and the third fluorescent ink layer. The ink for each fluorescent ink layer was applied so that regions overlapping with other fluorescent ink layers and non-overlapping regions were formed. The film thickness within each independent region was in the form of having a film thickness distribution in the range of 0.2 μm to 4 μm for all of the first fluorescent ink layer, the second fluorescent ink layer, and the third fluorescent ink layer.

[0129] The formulation of the ink for the fluorescent ink layer used for forming the first to third fluorescent ink layers is as follows. The following second fluorescent pigment is different from the following first fluorescent pigment. Also, the following third fluorescent pigment is different from the following first fluorescent pigment and the following second fluorescent pigment. <Fluorescent ink layer ink> · Thermosetting polyester resin (binder resin) · First fluorescent pigment (pearl pigment) in the ink for the first fluorescent ink layer: "Lumina Exterior Turquoise T303D" manufactured by D - BASF, 7.5 parts by mass of pearl pigment with respect to 100 parts by mass of the binder resin. · Second fluorescent pigment (pearl pigment) in the ink for the second fluorescent ink layer: "Mearlin Exterior CFS Super Copper 3503Z" manufactured by D - BASF, 5 parts by mass of pearl pigment with respect to 100 parts by mass of the binder resin. · Third fluorescent pigment (pearl pigment) in the ink for the third fluorescent ink layer: "Lumina Exterior Aqua Blue 7303D" manufactured by D - BASF, 7.5 parts by mass of pearl pigment with respect to 100 parts by mass of the binder resin. · Solvent (xylene, cyclohexanone)

[0130] On the entire surface of the shiny handle layer, the ink for the protective layer with the following formulation was applied by gravure offset printing so that the film thickness after drying would be 2 μm. <Ink for protective layer> · Thermosetting acrylic resin · Solvents (xylene, cyclohexanone)

[0131] On the protective layer, the ink for the raised layer with the following formulation was applied by gravure printing. The raised layer was formed so as to overlap a part of the shiny handle layer. For printing, an inclined dot gravure plate cylinder was used. As the said gravure plate cylinder, the one produced by a method of forming a desired cell pattern by laser beam exposure of a photosensitive resist film on the surface of a metal plate material and then etching the metal plate material was used. Thereafter, it was dried at 225 °C to form the raised layer. The average thickness of the raised layer was 10 μm. <Ink for raised layer> · Thermosetting acrylic resin · Acrylic resin particles (particle size 30 μm): 20 parts by mass with respect to 100 parts by mass of the binder resin · Silica: 8 parts by mass with respect to 100 parts by mass of the binder resin · Colorant (carbon black): 10 parts by mass with respect to 100 parts by mass of the binder resin · Solvents (xylene, cyclohexanone)

[0132] [Comparative Example 1] As the shiny handle layer, a decorative material of Comparative Example 1 was obtained in the same manner as in Example 1, except that only the first shiny ink layer (including Lumina Exterior Turquoise T303D manufactured by D - BASF as the shiny pigment) was formed on a part of the base material.

[0133] [Evaluation] <Appearance evaluation> Appearance evaluation was carried out on the decorative materials of the examples and comparative examples. Figure 7 is a photograph of the appearance of the cosmetic material of Example 1. In Example 1, with the shiny pattern layer, multi-color expression, color shading, and natural gradation could be expressed (especially the part surrounded by the solid line in Figure 7). Also, when observed at different angles, a change in brightness was felt. As a result, the pattern of real black iron sheet could be reproduced. Also, in the cosmetic material of Example 1, the visual effect (gloss-matte effect) and touch feeling (concavo-convex feeling) due to the raised layer were also confirmed.

[0134] On the other hand, for the cosmetic material of Comparative Example 1, although the glossiness due to the shiny pattern layer could be confirmed, since it was only a single color, it was not possible to express the visual effect and touch feeling like the real thing as in Example 1.
