Abstract
An article including a reflector having a first surface and a second surface opposite the first surface; a first selective light modulator layer external to the first surface of the reflector; a second selective light modulator layer external to the second surface of the reflector; a first absorber layer external to the first selective light modulator layer; and a second absorber layer external to the second selective light modulator layer; wherein each of the first and second selective light modulator layers include a host material is disclosed herein. Methods of making the article are also disclosed.
Claims16
A method for forming an article comprising:
- depositing on a substrate a first absorber layer;
- depositing on the first absorber layer a first selective light modulator layer;
- depositing on the first selective light modulator layer a reflector;
- depositing on the reflector a second selective light modulator layer;
- and
- depositing on the second selective light modulator layer a second absorber layer;
- wherein at least one of the first selective light modulator layer and the second selective light modulator layer is deposited using a liquid coating process;
- wherein each of the first and second selective light modulator layers comprises a solvent and the method further comprises evaporating the solvent from each of the deposited first and second selective light modulator layers before curing each of the deposited first and second selective light modulator layers;
- and
- wherein the liquid coating process is a process chosen from slot-bead, slide bead, slot curtain, slide curtain and gravure.
A method for forming an article comprising:
- depositing on a substrate a first absorber layer;
- depositing on the first absorber layer a first selective light modulator layer;
- depositing on the first selective light modulator layer a reflector;
- depositing on the reflector a second selective light modulator layer;
- and
- depositing on the second selective light modulator layer a second absorber layer;
- wherein at least one of the first selective light modulator layer and the second selective light modulator layer is deposited using a liquid coating process;
- wherein the first and second selective light modulator layer each independently include a selective light modulator particle chosen from a color shifting particle, a reflective pigment, quantum dots, fluorides, or mixtures thereof.
A method for forming an article comprising:
- depositing on a substrate a first absorber layer;
- depositing on the first absorber layer a first selective light modulator layer;
- depositing on the first selective light modulator layer a reflector;
- depositing on the reflector a second selective light modulator layer;
- and
- depositing on the second selective light modulator layer a second absorber layer;
- wherein at least one of the first selective light modulator layer and the second selective light modulator layer is deposited using a liquid coating process;
- wherein at least one of the first selective light modulator layer and the second selective light modulator layer includes at least one of (i) a photoinitiator including a phosphineoxide and (ii) an oxygen inhibition mitigation composition including at least one acrylate monomer and at least one acrylate oligomer.
