Patent ID: 8329289

Claim:
A composite, comprising inorganic and/or organic pigment and/or filler particles coated at least partially with a composition comprising calcium carbonate particles, and a binder, wherein the spherical equivalent diameter of the pigment and/or filler particles is in the micrometer range and the spherical equivalent diameter of the calcium carbonate particles is in the nanometer range; and the binder is a copolymer comprising as monomers one or more dicarboxylic acids and one or more monomers from the group of diamines, triamines, dialkanolamines or trialkanolamines, wherein the binder facilitates adhesion of the calcium carbonate particles to the surface of the pigment and/or filler particles, wherein the inorganic particles comprise talc, mica or a mixture thereof, and wherein the composite contains 0.1 to 10 wt% of the binder based on the total dry weight of the composite.
