The invention relates to an aqueous polymer dispersion containing A) a polymer dispersion produced by radical polymerization of ethylenically unsaturated monomers, B) stabilizing suitable for carrying out radical polymerization, in addition to C) 0.01 - 20.000 wt. ppm, in relation to the mass of the total dispersion, of at least one compound of general formula la and/or lb wherein R1, R2, R13 and R14 independently represent hydrogen, C1-C6-alkyl, C1-C6-alkoxy, carboxy, nitrile, isonitrile, cyano or halogen, R3 - R12 and R15- R24 independently represent hydrogen and selected organic radicals, and wherein at least one of the substituents R3 - R12or R15 - R24 represents hydroxyl and/or alkoxy and/or alkanoyloxy. The aqueous polymer dispersion can be used to coat foodstuffs, as a dye or as an adhesive and the films thus obtained are characterized by high fungicidal resistance. |
