OMNIDIRECTIONAL HIGH CHROMA RED STRUCTURAL COLOR WITH COMBINATION METAL ABSORBER AND DIELECTRIC ABSORBER LAYERS |
摘要 |
A high-chroma omnidirectional red structural color pigment. The omnidirectional structural color pigment is in the form of a multilayer stack that has a reflective core layer, a metal absorber layer extending across the reflective core layer and a dielectric absorber layer extending across the metal absorber layer. The multilayer stack reflects a single band of visible light with a hue between 0-40°, and preferably between 10-30°, on an a*b* Lab color map. The single band of visible light has a hue shift of less than 30° on the a*b* Lab color map when viewed from all angles between 0-45° normal to an outer surface of the multilayer stack. |

1. An omnidirectional high chroma red structural color comprising:
a multilayer stack having:
a reflective core layer;a metal absorber layer extending across said reflective core layer; anda dielectric absorber layer extending across said metal absorber layer; said multilayer stack reflecting a single band of visible light with a hue between 0-40° on an a*b* Lab color map, said single band of visible light having a hue shift within said 0-40° on said a*b* Lab color map when viewed from all angles between 0-45° normal to an outer surface of said multilayer stack. |
