The invention relates to an aqueous polymer dispersion containing a polymer, which can be produced by a radically initiated emulsion polymerization from ethylenically unsaturated, radically polymerizable monomers, wherein the polymerization of the monomers is carried out in the presence of a specific molecular weight regulator composition. The molecular weight regulator composition contains at least one mercaptoalkylcarboxylic acid ester of a C2 to C4 carboxylic acid and at least one oligomeric compound of formula R |
