The purpose of the present invention is to provide a composite pigment which can be dispersed and made into paint in a manner that saves labor compared with conventional flat emulsion paints, and which can achieve concealing properties and low glossiness (a luster reduction effect) without separately adding a matting agent. This composite pigment contains an inorganic compound and/or an organic compound, and a fixed extender pigment.

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.

An object is to reduce the occurrence of aggregation of an inorganic pigment that roughens the texture and dulls the color of a cosmetic containing the inorganic pigment. Porous pigment particles are provided which include cellulose or a cellulose derivative, and an inorganic pigment as main components. Also provided are a method for producing such particles, and a cosmetic containing such porous pigment particles. The particles are resistant to aggregation and are excellently dispersed in a base material to impart a color while improving the dullness problem. The particles of the present invention are porous particles that contain cellulose and have a wrinkle-like or fold-like uneven structure on the surface thereof (that is, have an appropriate amount of pores or voids). Thus, the particles of the present invention have soft and comfortable texture and are suitably added to cosmetics that are directly applied to the skin.

For the cosmetic field, omniphobic cosmetic pigments under the form of a core shell structure: the core is or includes of a metal oxide on which is adsorbed poly(β-(1.fwdarw.4)-D-glucosamine) chains; the chains being acetylated, or partially or totally deacetylated. Also, the process for manufacturing the omniphobic cosmetic pigments, including: (i) preparing an acidic aqueous solution including metal oxide particles and a poly (β-(1.fwdarw.4)-D-glucosamine), the poly (β-(1.fwdarw.4)-D-glucosamine) being acetylated, or partially or totally deacetylated; and (ii) increasing the pH until 12, of the solution obtained at step (i) in order to obtain the adsorption of said poly (β-(1.fwdarw.4)-D-glucosamine on the metal oxide particles and the precipitation of the resulting metal oxide particles coated with the poly (β-(1.fwdarw.4)-D-glucosamine.
