Abstract: The present invention relates to a composition comprising an aqueous dispersion of cerium (III) carbonate particles having a z-average particle size in the range of from 5 nm to 500 nm, which composition further comprises a capping ligand. The composition is useful as an additive in formulations that contain polymer, pigments, dyes, or tints, or a combination thereof, to promote color retention and attenuate unwanted color formation in coatings formed from these formulations.

Abstract: 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.
