Multilayer articles containing organic layers
An article includes a first organic layer and a second organic layer each with an interior embossed surface; and an embossed reflector layer adjacent to the interior embossed surface of the first organic layer and adjacent to the interior embossed surface of the second organic layer. A method of making an article is also disclosed.
1. A method of making an article, comprising:
coating a first organic layer onto a substrate, wherein the first organic layer includes an organic material and a colorant;
depositing a reflector layer onto the first organic layer;
embossing both of the reflector layer and the first organic layer, and
coating a second organic layer onto the embossed reflector layer using a liquid coating process, wherein the liquid coating process is chosen from slot-die, inkjet, curtain coating, metering rod, myer bar coating, flexo, offset printing, slot-bead, slide bead, slot curtain and slide curtain, wherein the liquid coating process comprises coating a coating composition in liquid form and wherein the liquid coating process does not include vaporization of the liquid coating composition;
wherein the article is a diffractive pigment.
2. The method of claim 1 , wherein the second organic layer includes a colorant, and the first organic layer and the second organic layer are a same color.
3. The method of claim 1 , wherein the first organic layer and the second organic layer are different colors.
4. The method of claim 1 , wherein the first organic layer and the second organic layer include a same organic material.
5. The method of claim 1 , wherein the first organic layer and the second organic layer include a different organic material.
6. The method of claim 1 , further comprising a second absorber layer adjacent to the second organic layer.
7. The method of claim 1 , wherein the liquid coating process is self-leveling.
8. The method of claim 1 , wherein depositing the reflector layer uses a vacuum deposition process.
9. The method of claim 1 , wherein an exterior surface of the second organic layer is substantially planar.
10. The method of claim 1 , wherein the substrate includes a release layer.
11. The method of claim 10 , wherein the release layer is a polyvinyl alcohol.
12. The method of claim 10 , further comprising releasing the substrate.
13. The method of claim 12 , wherein the reflector layer is on a first side of the first organic layer, the article further comprising a first absorber layer adjacent to a second side of the first organic layer, the second side of the first organic layer being opposite the first side of the first organic layer.
14. The method of claim 1 , wherein the substrate further includes an embossable layer.
15. The method of claim 1 , further comprising releasing the substrate from the article.
16. The method of claim 15 , wherein the reflector layer is adjacent to a first surface of the first organic layer and a first surface of the second organic layer, the article further comprising a first absorber layer and a second absorber layer, the first absorber layer being adjacent to a second surface of the first organic layer that is opposite the first surface of the first organic layer and the second absorber layer being adjacent to a second surface of the second organic layer that is opposite the first surface of the second organic layer.
