Patent ID: 8487022

Claim:
A composition comprising: a) from 0.1 to 30% by weight, based on the total weight of the composition, of a colouring pigment, b) from 0.1 to 20% by weight, based on the total weight of the composition of a starch/latex copolymer, c) from 0 to 20% by weight, based on the total weight of the composition, of starch or a starch derivative, d) from 0 to 10% by weight, based on the total weight of the composition, of one or more auxiliaries and e) water to complete to 100% by weight, based on the total weight of the composition, wherein the starch/latex copolymer is obtained by copolymerization of: i) from 20 to 40% by weight of a styrene or a substituted styrene, ii) from 20 to 50% by weight of an acrylate or a methacrylate and iii) from 5 to 20% by weight of one or more further ethylenically unsaturated monomers, in the presence of from 15 to 40% by weight of starch, wherein the further ethylenically unsaturated monomer is selected from the group consisting of: alkyl vinyl ketones, a substituted acrylamide, a methacrylic acid, crotonic acid, itaconic acid, fumaric acid, maleic acid, maleic anhydride, a vinyl halide, vinylidene halide, a vinyl ester, a vinyl ether, vinyl carbazole, N-vinyl pyrrolidone, vinyl pyridine, ethylene, propylene, isobutylene, vinyl acetate, acrylic acid, and a monovinyl silicon compound.
