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.

Modified copper chromite spinel pigments exhibit lower coefficients of thermal expansion than unmodified structures. Three methods exist to modify the pigments: (1) the incorporation of secondary modifiers into the pigment core composition, (2) control of the pigment firing profile, including both the temperature and the soak time, and (3) control of the pigment core composition.

Provided is a method for producing a composite material in which the dispersibility of an exfoliated layered substance in a resin or the like is improved and with which a synthetic resin having significantly improved properties, such as impact resistance, can be obtained. A method for producing a composite material including an exfoliated layered substance and a coating substance coating a surface of the exfoliated layered substance includes a disintegrating step of disintegrating secondary particles of an exfoliated layered substance in a solution containing a coating substance, or a method for producing a composite material including an exfoliated layered substance and a coating substance coating a surface of the exfoliated layered substance includes a disintegrating step of disintegrating secondary particles of an exfoliated layered substance in a solvent and a dissolving step of dissolving a coating substance in a dispersion containing the exfoliated layered substance that has been disintegrated.
