摘要： The present invention is a multilayered composite comprising porous metal oxide particles that are covalently bonded by way of inorganic ether groups to one or more sites of a first polyhydroxyl-functionalized polymer. This first polymer is in turn covalently bonded by way of inorganic ether groups to one or more sites of a second polyhydroxyl-functionalized polymer. The multilayered composites can be prepared by contacting porous inorganic-oxide particles with a sufficient amount of OH-reactive crosslinking agent to form metal oxide particles imbibed with the crosslinking agent, and then contacting the inorganic-oxide particles with a solution of polyhydroxyl-functionalized polymer under reactive conditions.

摘要： The present invention relates to a composition comprising a) a stable aqueous dispersion of inorganic pigment particles hydrophobically modified with covalently bonded polysiloxane or silyl groups; and b) a polymeric anionic dispersant; wherein the hydrophobically modified inorganic pigment particles have an average particle size in the range of from 200 nm to 10 μm, and the solids content of the hydrophobically modified inorganic pigment particles is from 10 to 80 weight percent, based on the weight of inorganic pigment particles and water. The composition of the present invention provides a way to improve water resistance in coatings formulations.

摘要： The present invention is a composition comprising an aqueous dispersion of metal oxide pigment particles coated with a polymer comprising structural units of an alkyltrihydroxysilane or a salt thereof. 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.
