Patent ID: 8349939

Claim:
A method for producing 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, the method comprising the steps of: a) providing inorganic and/or organic pigment and/or filler particles having a spherical equivalent diameter in the micrometer range; b) providing calcium carbonate particles having a spherical equivalent diameter in the nanometer range; c) providing a binder that 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; d) mixing the pigment and/or filler particles from a) and the calcium carbonate particles from b), wherein the binder is added to the pigment and/or filler particles from a) or to the calcium carbonate composition from b) before step d) and the resulting reaction mixture is homogenized, wherein the inorganic pigments 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.
