Abstract

The application discloses an optical thin film, a structural color pigment and a preparation method of the optical thin film. The optical thin film comprises a plurality of film layers with two high and low refractive indexes, wherein the plurality of film layers are laminated in a mode that two high and low refractive indexes are alternative; the plurality of film layers comprise an intermediatefilm layer; and in the intermediate film layer and other film layers positioned on one side of the intermediate film layer, the film layers with the same refractive indexes are different or not completely the same in optical thickness. In the mode, according to the application, brightness of the optical thin film can be improved.

Description

technical field [0001] The present application relates to the technical field of optical thin films, in particular to an optical thin film, a structural color pigment and a preparation method of the optical thin film. Background technique [0002] Structural color, also known as physical color, is a physical color-producing effect that is produced by the interaction, diffraction or scattering of micro-nano structures at the wavelength scale of light and light. As a new generation of pigments, structural color pigments have a series of important advantages such as high brightness, high color saturation, non-toxic, non-fading, high temperature resistance, and environmental protection. [0003] The inventors of the present application have discovered in the course of long-term research that existing structural color pigments have the problem of low brightness. Contents of the invention [0004] The technical problem mainly solved by this application is to provide an optical ...
