    摘要： An aqueous polymer emulsion obtainable by free radical polymerization of monomers in aqueous emulsion in the presence of a polymeric protective colloid contains, as components,from 5 to 50% by weight of at least one ethylenically unsaturated monomer having at least one acid or acid anhydride group (monomers I),from 0.1 to 80% by weight of at least one (meth)acrylate of an aliphatic alcohol of at least 10 carbon atoms (monomers II),from 0 to 94.9% by weight of main monomers selected from the group consisting of C.sub.1 -C.sub.8 -alkyl (meth)acrylates, vinyl esters of carboxylic acids of up to 20 carbon atoms, vinyl aromatics of up to 20 carbon atoms, ethylenically unsaturated nitriles, vinyl halides and aliphatic hydrocarbons having 2 to 8 carbon atoms and 1 or 2 double bonds (monomers III) andfrom 0 to 60% by weight of further monomers (monomers IV),the stated weights being based on the polymeric protective colloid.
