A method of manufacturing a pigment. The method includes: providing a substrate; forming stacked multiple sets of films successively on the substrate, wherein each set of films comprises a sacrificial layer and an optical film, the sacrificial layer and the optical film are successively stacked, and the sacrificial layer is a stripping agent with compressive stress or low stress; and obtaining the pigment by stripping and crushing formed multiple sets of films.

Method of manufacturing pigment

The present disclosure provides an optical film, a structural colored pigment, and a method for preparing an optical film. The optical film includes a multilayer film. The multilayer film includes films with high refractive indexes and films with low refractive indexes alternately arranged in a multilayer manner, and a middle film. Some of the films with the high refractive indexes and some of the films with the low refractive indexes are disposed on a side of the middle film, constituting first other films. Optical thicknesses of films having a same refractive index in the optical films and an optical thickness of the middle film are all different or partially different.
