Abstract

An article includes at least one layer including a transparent portion and at least one metal portion; and a color-rendering layer; wherein the at least one metal portion is positioned in the article to provide reflection of incident light; and wherein the transparent portion is dimensioned to allow at least some incident light to pass through. A method of making an article is also disclosed.

First claim

What is claimed is:

1. A symmetrical flake, comprising:
at least one layer comprising a transparent portion and at least one metal portion; and
a color-rendering layer;
wherein the at least one layer includes a first layer and a second layer positioned with the color-rendering layer therebetween;
wherein the at least one metal portion is positioned with the transparent portion in both the first layer and the second layer to provide reflection of incident light;
wherein the transparent portion is dimensioned to allow at least some incident light to pass through to the color-rendering layer,
wherein the at least one layer is a selective light modulator layer having a thickness from about 1 nm to 10000 nm and including a curing agent.

2. The symmetrical flake of claim 1 , wherein the at least one metal portion is positioned with the transparent portion, such that the transparent portion is dimensioned to allow at least some incident light to pass to the to the at least one metal portion.

3. The symmetrical flake of claim 1 , wherein the at least one metal portion is a plurality of metal platelets that are randomly dispersed throughout the transparent portion of the at least one layer.

4. The symmetrical flake of claim 1 , wherein the at least one metal portion is a plurality of metal beads that are randomly dispersed throughout the transparent portion of the at least one layer.

5. The symmetrical flake of claim 1 , wherein the at least one metal portion is a plurality of organic beads coated with a metal reflector layer.

6. The symmetrical flake of claim 1 , wherein the at least one metal portion is a plurality of inorganic beads coated with a metal reflector layer.

7. The symmetrical flake of claim 1 , wherein an amount of the at least one metal portion present in the at least one layer determines an amount of metal sheen produced.

8. The symmetrical flake of claim 1 , wherein the transparent portion comprises a clear resin selected from the group of polyacrylates, polymethacrylates, polystyrenes, polyvinyl acetates, polyurethanes, polyvinyl chlorides, polyvinyl alcohols, polyesters, polycarbonates, polyamides, polyimides, silicones, epoxies, and copolymers thereof.

9. The symmetrical flake of claim 1 , wherein the color-rendering layer is opaque.

10. The symmetrical flake of claim 1 , wherein the color-rendering layer is white.

11. The symmetrical flake of claim 1 , wherein the color-rendering layer comprises light absorbing or light scattering materials.

12. The symmetrical flake of claim 1 , wherein the color-rendering layer comprises at least one of dyes and colorants.

13. A method of making the symmetrical flake of claim 1 , comprising:
forming the first layer comprising the transparent portion and the at least one metal portion on a substrate;
forming the color-rendering layer onto the first layer; and
forming the second layer comprising the transparent portion and the at least one metal portion on the color-rendering layer.

14. The method of claim 13 , further comprising curing the formed first layer.

15. The method of claim 13 , further comprising curing the formed second layer.

16. The method of claim 13 , further comprising curing the formed color-rendering layer.

17. The method of claim 13 , further comprising reflecting light from the at least one metal portion to produce a metal sheen.

18. The method of claim 13 , wherein the steps of forming the first layer, forming the color-rendering layer, and forming the second layer comprise a deposition process or liquid coating process.

19. The method of claim 13 , wherein the formed first layer, the formed color-rendering layer, and the formed second layer in combination are released from the substrate.

20. The method of claim 19 , a release layer is formed between the substrate and the first layer that enables the release.
