Patent ID: 8436088

Claim:
A composition containing a) mineral filler, the proportion of particles having a diameter of at least 40 μm being at least 40% by weight, wherein the mineral filler is present in an amount of from 50 to 80% by weight, based on the total formulation, b) pigment, c) colloidal silica and d) aqueous plastics dispersion which contains a copolymer which is prepared by emulsion polymerization and is derived from A) at least 40% by weight, based on the total amount of monomer, of esters of α,β-unsaturated carboxylic acids, vinyl esters of saturated carboxylic acids, vinylaromatic monomers or combinations of two or more of these monomers, B) from 0.1 to 10% by weight, based on the total amount of monomers, of α,β-ethylenically unsaturated mono- and/or dicarboxylic acids and/or of α,β-ethylenically unsaturated sulfonic acids and/or of α,β-ethylenically unsaturated phosphoric acids and/or of α,β-ethylenically unsaturated phosphonic acids and/or of amides of α,β-ethylenically unsaturated mono- and/or dicarboxylic acids, C) from 0.5 to 15% by weight, based on the total amount of monomers, of ethylenically unsaturated monomers which have at least one alkoxysilyl group, D) from 0.1 to 10% by weight, based on the total amount of monomers, of an ethylenically unsaturated surface-active monomer containing at least one anionic and/or nonionic emulsifying group and E) optionally up to 20% by weight, based on the total amount of monomers, of other monomers copolymerizable with the monomers of groups A), B), C) and D), with the proviso that, instead of or in addition to the copolymerization of the monomer C), from 0.5 to 15% by weight, based on the total amount of monomers, of a monomer which has at least one amino, mercapto or epoxide group in addition to at least one alkoxysilyl group is added after the emulsion polymerization.
