Patent ID: 8378007

Claim:
Colored polymer particles comprising 5% to 95% by weight of at least one pigment and a polymerized coating prepared by polymerizing 2.5% to 50% by weight of a polymerizable wax D, in which the polymerizable function is an ethylenically unsaturated group, with 2.5% to 50% by weight of a monomer B having a functional group which reacts with the ethylenically unsaturated group of D, the weight percentages being based in each case on the total weight of the coated pigment particles, and the sum of the weight percentages not exceeding 100% by weight, wherein the polymerizable wax D is a reaction product of a polyol, long-chain aliphatic carboxylic acids, and at least one ethylenically unsaturated carboxylic acid, and optionally, oligomerized by the addition of a dicarboxylic acid.
