Patent ID: 8313575

Claim:
A pigment preparation comprising (a) 5% to 70% by weight of at least one pigment P coated with at least one polymerizable, ethylenically unsaturated compound B; (b) 0.1% to 15% by weight of at least one nonionic surface-active additive C based on polyethers, polyglycerols or both; (c) 0.1% to 15% by weight of at least one anionic surface-active additive D based on sulfonates, sulfates, carboxylates, phosphonates or phosphates; (d) 10% to 90% by weight of water; (e) 0% to 20% by weight of at least one auxiliary, wherein the polymerizable, ethylenically unsaturated compound B is a reaction product of a polyol, aliphatic carboxylic acids having more than 7 carbon atoms, and at least one ethylenically unsaturated carboxylic acid, optionally oligomerized by the addition of a dicarboxylic acid; and the sum of the weight percentages not exceeding 100% by weight of the total pigment preparation.
