Abstract
Claims
1. A decorative laminate including a first surface and a second surface, The device comprises, in this order, a shaping layer including a shaping surface having an uneven structure formed from the first surface to the second surface, and a brightness adjustment layer covering the shaping surface of the shaping layer. The device has at least one unit optical element that reflects, refracts, and / or diffracts incident light with the first surface as the incident surface according to the shape of the uneven structure, In the unit optical element, the shaping surface includes a plurality of tilted surfaces that are aligned toward an arbitrary reference line extending along the normal direction of the decorative laminate and tilted toward the reference line, and a plurality of connecting surfaces that connect adjacent tilted surfaces. The angle of the tilted surface with respect to the normal direction is greater than the angle of the connecting surface connected to the tilted surface with respect to the normal direction. A decorative laminate in which the color of the decorative laminate when the first surface is observed with light incident on the first surface is complementary to the color of the decorative laminate when the first surface is observed with light incident on the second surface.
2. a 1 and b 1 and, a 2 and b 2 The color difference △E, expressed by the following formula, is 40 or greater. the aforesaid a 1 and the aforesaid b 1 are, respectively, the L * a * b * value and b * value in the a * value in the b color system when observing the first surface of the decorative laminate with light having the first surface as an incident surface in measurement by the SCE method, The a 2 and the aforementioned b 2 These are the L values of the decorative laminate when the first surface is observed with light incident on the second surface in the SCE method measurement. * a * b * a in the color system * Value and b * The decorative laminate according to claim 1, which is a value. △E=((a 1 -a 2 ) 2 +(b 1 -b 2 ) 2 ) 1/2
3. a 1 and a 2 The product of and b 1 and b 2 At least one of the products of is less than 0, The a 1 and the aforementioned b 1 These are the L values of the decorative laminate when the first surface is observed with light incident on the first surface during measurement using the SCE method. * a * b * a in the color system * Value and b * It is a value, The a 2 and the aforementioned b 2 These are the L values of the decorative laminate when the first surface is observed with light incident on the second surface in the SCE method measurement. * a * b * a in the color system * Value and b * The decorative laminate according to claim 1, which is a value.
4. In measurement using the SCE method, when the first surface is observed with light incident on that first surface, the L of the decorative laminate * a * b * L in the color system * The decorative laminate according to claim 1, wherein the value is 4 or more and 15 or less.
5. The brightness adjustment layer is a colored layer containing pigment, The decorative laminate according to claim 1, wherein the pigment comprises at least one of the following: phthalocyanine-based pigment, dioxazine-based pigment, quinacridone-based pigment, isoindolinone-based pigment, condensed azo-based pigment, nickel azo, disazo, benzimidazolon, naphthol-based, cobalt-based, iron oxide, or titanium-based pigment.
6. The decorative laminate according to claim 1, wherein the sum of the heights of the plurality of tilted surfaces in the at least one unit optical element is 4% or more and 30% or less of the sum of the widths of the plurality of tilted surfaces in the at least one unit optical element.
7. At least one of the plurality of tilting surfaces is a first tilting surface, The width of the first tilting surface is 5.0 times or more the height of the first tilting surface. The decorated laminate according to claim 1, wherein, in observation from the normal direction, the area of the at least one first tilted surface is 20% or more and 100% or less of the area of the unit optical element on which the at least one first tilted surface is located.
8. Including a transparent portion and a light-shielding portion, The decorative laminate according to claim 1, wherein the brightness adjustment layer includes a portion located in the light-transmitting portion and a portion located in the light-shielding portion.
9. A decorative laminate according to any one of claims 1 to 8, A decorative member comprising a molded portion that overlaps the decorative laminate from the second surface side.
10. The decorative member according to claim 9, wherein the molded portion has visible light shielding properties.
11. A housing having an opening, A decorative molded product comprising a decorative member according to claim 9 that covers the opening.
12. The housing is a decorative molded product according to claim 11, wherein the housing has visible light shielding properties.
13. Light source and A display system comprising: a decorative member according to claim 9 that overlaps with the light source.
