Abstract

A polymer composed offrom 5 to 95% by weight of a mixture of at least one C2-C4-alkyl acrylate and at least one C6-C12-alkyl acrylate (monomers a),from 5 to 30% by weight of ethylenically unsaturated compounds having a glass transition temperature of above 0° C. and containing no functional groups other than the ethylenically unsaturated group (monomers b),from 0 to 10% by weight of ethylenically unsaturated compounds having at least one acid group or acid anhydride group (monomers c), andfrom 0 to 60% by weight of further ethylenically unsaturated compounds (monomers d),the amounts by weight being based on the emulsion polymer.
