Abstract:
An aqueous polymer dispersion obtained by emulsion polymerization of a monomer mixture A) comprising from 50 to 100% by weight of C.sub.1 -C.sub.18 alkyl (meth)acrylates, vinyl esters, vinylaromatic compounds, or mixtures thereof, in the presence of a protective colloid B) composed ofb.sub.1) from 2 to 40% by weight of ethylenically unsaturated copolymerizable compounds (monomers) having at least one phosphate or phosphonate groupb.sub.2) from 0 to 98% by weight of C.sub.1 -C.sub.18 alkyl (meth)acrylates, vinyl esters or vinylaromatic compoundsb.sub.3) from 0 to 50% by weight of further monomers, the amounts by weight being based on the protective colloidwherein the sum of the % by weight of b.sub.1 +b.sub.2 +b.sub.3 is 100% of the total amount of protective colloid B.
