Abstract:
1. A colored polymer dispersion comprising as essential constituents (a) a color polymer prepared by polymerizing monomer A with monomer B, wherein monomer A is a pigment P coated with a polymerizable wax D and wherein the polymerizable function is an ethylenically unsaturated group, and monomer B being an ethylenically unsaturated compound; (b) at least one nonionic surface-active additive E selected from the group consisting of polyethers, polyglycerols and a mixture thereof; (c) at least one anionic surface-active additive F selected from the group consisting of sulfonates, sulfates, phosphonates, phosphates, carboxylates or a mixture thereof; (d) water, wherein the polymer dispersion comprises: from 2% to 60% by weight of the component (a), from 0.1% to 15% by weight of the component (b), from 0.1% to 15% by weight of the component (c), from 10% to 90% by weight of the component (d) (water), from 0% to 20% by weight of at least one auxiliary, the sum of the weight percentages not exceeding 100% by weight, wherein the pigment P is selected from the group consisting of an organic chromatic pigment, an inorganic chromatic pigment, a white pigment, a carbon black pigment and a combination thereof, and wherein the monomer B is selected from the group consisting of acrylates, methacrylates and vinylbenzenes.
