Aqueous polymer dispersion set to pH of 4-6, has 100 pbw homopolymer or copolymer produced by emulsion polymerization, 0.1-15 pbw (based on total monomer) protective colloid(s) having no cellulose ether or up to 0.45 pbw cellulose ether (based on total monomer), 0.1-10 pbw (based on total amount of monomers) nonionic emulsifier(s), 10-990 ppm by weight (based on mass of total dispersion) antioxidant(s), and polyene fungicide(s). Independent claims are also included for: (A) a process for producing aqueous polymer dispersions comprising free-radical emulsion polymerization of at least one ethylenically unsaturated monomer for producing a homopolymer or copolymer in the presence of 0.1-15 pbw protective colloid and 0.1-10 pbw nonionic emulsifier(s), optionally addition of antioxidant(s) so that the concentration of antioxidant in the polymer dispersion is 10-990 ppm by weight (based on the mass of the total dispersion), optionally setting the resultant aqueous polymer dispersion to a pH of 4- 6, optionally addition of further additives coating foods, and addition of polyene fungicide; and (B) a coating and/or packaging food as a coating cheese comprising the aqueous polymer dispersion. |
