Title: COMPOSITE PIGMENT AND PRODUCTION METHOD THEREOF, PAINT COMPOSITION CONTAINING COMPOSITE PIGMENT, AND COATING FILM
Abstract:
The purpose of the present invention is to provide: a composite pigment, and production method thereof, which can suppress luster of a coating film by modifying an inorganic coloring pigment, and which can be used in various applications such as low-gloss (luster reduction effect) pigments and matte pigments; a paint composition which can achieve both an excellent coating film texture and also the property of having low gloss and luster even when added to a coating film; and a coating film. In this composite pigment, the inorganic coloring pigment is fixed by an inorganic compound, and a plurality of particles of the inorganic coloring pigment are aggregated into granular form through the inorganic compound.
