A description is given of an aqueous polymer dispersion comprising
A) a polymer dispersion produced by free-radical polymerization of ethylenically unsaturated monomers,
B) stabilizers suitable for carrying out the free-radical polymerization, and also
C) 0.01 to 20 000 ppm by weight, based on the mass of the total dispersion, of at least one compound of the formula Ia and/or Ib
where R

The aqueous polymer dispersion may be used for coating foods, as color, or as adhesive, and the resultant films are distinguished by high fungicidal resistance.
