<p>PROBLEM TO BE SOLVED: To provide a high-chroma omnidirectional structural color multi-layer structure pigment with a reduced number of thin film layers.SOLUTION: A high-chroma omnidirectional structural color multi-layer structure includes a multi-layer stack having a core layer, a dielectric layer 110 extending over the core layer and an absorption layer 120 extending over the dielectric layer. A boundary surface 112 is present between the dielectric layer and the absorption layer. At a first incidence electromagnetic wavelength, a nearly zero electric field is present in the boundary surface. At a second incidence electromagnetic wavelength, a large electric field is present in the boundary surface. In the boundary surface, the multi-layer stack has a narrow reflection band of shorter than 300 nm and a color phase shift of smaller than 30°, in the view at an angle of 0-45°, so that reflection light of a narrow band is generated by the multi-layer stack, which allows high transmission of the first incidence electromagnetic wavelength and high absorption of the second incidence electromagnetic wavelength.</p> |
