Fungicidally Active Polymer Dispersions And Use Thereof

摘要

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 R¹, R², R¹³ and R¹⁴ independently of one another are hydrogen, C₁-C₆-alkyl, C₁-C₆-alkoxy, carboxyl, nitrile, isonitrile, cyano or halogen, R³ to R¹² and R¹⁵ to R²⁴ independently of one another are hydrogen and selected organic radicals, and at least one of the substituents R³ to R¹², or R¹⁵ to R²⁴, being hydroxyl and/or alkoxy and/or alkanoyloxy. 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.
