Abstract: The present invention relates to the use of aqueous polymer dispersions of a polymer P obtainable by emulsion polymerization of ethylenically unsaturated monomers M in the presence of at least one anionic emulsifier as binders in a waterborne coating formulation having a pH of at least pH 9.5. The polymer dispersion is an aqueous polymer dispersion of a polymer P obtainable by emulsion polymerization of ethylenically unsaturated monomers M in the presence of at least one anionic emulsifier, where the monomers M comprise or consist of the following monomers M1, M2 and optionally M3 and/or M4 a) 90 to 99.9% by weight, based on the total weight of monomers M, of monomers M1 selected from the group consisting of C
