Abstract: The invention relates to an essentially solvent-free aqueous preparation containing pigments which comprises: i) at least one polymer A in the form of polymer particles distributed in a dispersed manner, wherein the polymer particles comprise 80 wt. % to 99.9 wt. %, with regard to the total weight of polymer A, of a water-insoluble polymer 1 having a glass transition temperature TG1 ranging from -50 to +40 DEG C synthesized from ethylenically unsaturated monomers M1, and 0.1 to 20 wt. %, with regard to the total weight of polymer A, of one or more water-insoluble polymers i having a glass transition temperature TGi above 50 DEG C synthesized from ethylenically unsaturated monomers Mi; ii) at least one pigment and optionally one or more fillers.

Abstract: A process for preparing aqueous polymer dispersions comprises first of all subjecting ethylenically unsaturated monomers to free-radical aqueous emulsion polymerization to prepare an aqueous dispersion of a polymer 1 having a glass transition temperature Tg1, then dissolving further, comparatively hard monomers in the dispersed particles of the polymer 1, and subsequently carrying out free-radical polymerization of the monomers dissolved in the particles.
