The present invention is a composition comprising an aqueous dispersion of metal oxide pigment particles coated with an organosilane polymer comprising structural units of an alkyltrihydroxysilane or a salt thereof, a dialkyldihydroxysilane or a salt thereof, and an ancillary alkylsilane triol. The composition of the present invention provides hydrophobicity to pigment particles, thereby imparting water resistance, and allows for high loadings of pigment in water without increased viscosity. The dispersion is further useful for providing stain and corrosion resistance in coatings arising from paints.

Described herein are compositions comprising xanthommatin, or a derivative or precursor thereof, and a paint matrix. Within the composition, the xanthommatin, or a derivative or precursor thereof, is in molecular form, not as a particle, and is uniformly distributed throughout a paint matrix. This provides paint coatings with specific thermal performance and desired visible color. Also described herein are methods of preparing and using the compositions described herein.

The present invention relates to a titanium dioxide pigment composition for use in paint formulations, wherein the pigment composition comprises a plurality of titanium dioxide particles, and a dispersant package deposited on the surfaces of the titanium dioxide particles.

A high solid content aqueous white pigment paste includes: TiO.sub.2 powders; an anionic polyelectrolyte; a charge regulator; an pH regulator; and water. Herein, based on a total weight of the aqueous white pigment paste, the content of the TiO.sub.2 powders is 65 to 80 wt %, and a weight ratio of the TiO.sub.2 powders to the anionic polyelectrolyte ranges from 130 to 180.
