    Abstract: The present invention relates to aqueous polymer dispersions, which are obtainable by a free radical aqueous emulsion polymerization of ethylenically unsaturated monomers M, which comprise a) 0.5 to 7.0% by weight, based on the total weight of monomers M, of a combination of a1 ) at least one monomer Ma1, selected from monoethylenically unsaturated monocarboxylic acids having 3 to 6 carbon atoms and the salts thereof; a2) at least one monomer Ma2, selected from monoethylenically unsaturated dicarboxylic acids having 4 to 8 carbon atoms and the salts thereof; a3) at least one monomer Ma3, selected from monoethylenically unsaturated monosulfonic acids having 2 to 10 carbon atoms and the salts thereof; b1) 60 to 79.45% by weight, based on the total weight of monomers M, of at least one monomer Mb1, which is selected from nonionic monoethylenically unsaturated monomers having a solubility in deionized water of at most 60 g/L at 25°C and 1 bar, and whose homopolymers have a glass transition temperature Tg of at least 50°C; b2) 20 to 39.45% by weight, based on the total weight of monomers M, of at least one monomer Mb2, which is selected from nonionic monoethylenically unsaturated monomers having a solubility in deionized water of at most 60 g/L at 25°C and 1 bar, and whose homopolymers have a glass transition temperature Tg of at most 40°C; c) 0.05 to 2.0% by weight of at least one crosslinking monomer Mc; where the aqueous emulsion polymerization is carried out at least partly in the presence of a chain transfer compound. The invention also relates to a process for producing the aqueous polymer dispersions. The aqueous polymer dispersions are useful as binders in water-borne coating formulations, in particular as binder in water-borne coating formulations for shaped mineral articles.
