An aqueous polymer dispersion for use as binder and coating agent for pharmaceutical dosage forms, obtained by free-radical polymerization in an aqueous system in the presence of a polymerization initiator of i) 60 to 99.95% by weight of at least one monomer selected from the group consisting of alkyl acrylates, alkyl methacrylates and vinyl esters of C<SUB>1</SUB>-C<SUB>24 </SUB>carboxylic acids, ii) 0.05 to 5% by weight of a monoolefinically unsaturated C<SUB>3</SUB>-C<SUB>8 </SUB>carboxylic acid iii) 0 to 35% by weight of further free-radical polymerizable monomers, where the total of i), ii), and iii) equals 100% by weight, in the presence of 0.001 to 1.0% by weight, based on the total weight of the monomers, of an anionic emulsifier.
