Abstract

An article includes a reflector having a first surface, a second surface opposite the first surface, and a third surface; and a first selective light modulator layer external to the first surface of the reflector; wherein the third surface of the reflector is open. A method of making an article is also disclosed.

First claim

What is claimed is:

1 . An article comprising:
a reflector having a first surface, a second surface opposite the first surface, and a third surface; and a first selective light modulator layer external to the first surface of the reflector; wherein the third surface of the reflector is open.

2 . The article of claim 1 , further comprising a first absorber layer external to the first selective light modulator layer;
wherein the first selective light modulator layer is at least one of non-absorbing and absorbing.

3 . The article of claim 2 , further comprising a second light selective light modulator layer external to the first absorber layer;
wherein the first selective light modulator layer is non-absorbing, and the second light selective light modulator layer is absorbing.

4 . The article of claim 1 , further comprising a magnetic-containing layer having a first surface and a second surface opposite the first surface;
wherein the reflector layer is external to the first surface of the magnetic-containing layer.

5 . The article of claim 4 , further comprising a first absorber layer external to the first selective light modulator layer;
wherein the first selective light modulator layer is non-absorbing.

6 . An article, comprising:
a transparent layer having a first surface, a second surface opposite the first surface, and a third surface; and a first selective light modulating layer external to the first surface of the transparent layer; wherein the third surface of the transparent layer is open.

7 . The article of claim 6 , further comprising a second selective light modulating layer external to the second surface of the transparent layer.

8 . The article of claim 1 , further comprising a release layer.

9 . An optical device comprising the article of claim 1 .

10 . A composition comprising the optical device of claim 9 and a liquid medium.

11 . The article of claim 1 , wherein the article is a flake.

12 . The article of claim 1 , wherein the first selective light modulator layer selectively absorbs specific wavelengths of energy.

13 . The article of claim 1 , having a lamellar shape.

14 . The article of claim 1 , wherein the article exhibits a property chosen from optical interference, light absorption, light reflection, light scattering, and combinations thereof.

15 . A method for manufacturing an article comprising:
depositing a reflector layer; and depositing a first selective light modulator layer; wherein the first selective light modulator layer is deposited using a liquid coating process.

16 . The method of claim 15 , further comprising depositing a first absorber layer, wherein the first selective light modulator layer is at least one of non-absorbing and absorbing.

17 . The method of claim 16 , further comprising depositing a second selective light modulator layer, wherein the first selective light modulator layer is non-absorbing.

18 . The method of claim 15 , further comprising depositing between the substrate and the reflector layer a magnetic-containing layer.

19 . The method of claim 18 , further comprising depositing a first absorber layer, wherein the first selective light modulator layer is non-absorbing.

20 . The method of claim 17 , wherein the second selective light modulator layer is deposited using a liquid coating process.
