An aqueous polymer dispersion whose polymer, present in disperse distribution, is composed in free-radically polymerized form offrom 20 to 65% by weight of at least one vinylaromatic monomer (monomers A),from 30 to 75% by weight of at least one monomer having two conjugated, ethylenically unsaturated double bonds (monomers B), andfrom 0.5 to 10% by weight of at least one other monomer, C, selected from the group consisting of alpha,beta-monoethyienically unsaturated mono- and dicarboxylic acids and amide or ester derivatives thereofand whose alkali metal ion content GA, based on the mass of the dispersed polymer, is >=0.5% by weight, the pH of the aqueous dispersion medium being adjusted to a value below 6.
