Abstract

The use of a copolymer (A) preparable by free-radical polymerization ofa) at least one olefinically unsaturated monomer, andb) at least one olefinically unsaturated monomer different than the olefinically unsaturated monomer (a), of the general formula IR1R2C═CR3R4  (I)  in which the radicals R1, R2, R3 and R4 each independently of one another are hydrogen atoms or substituted or unsubstituted alkyl, cycloalkyl, alkylcycloalkyl, cycloalkylalkyl, aryl, alkylaryl, cycloalkylaryl, arylalkyl or arylcycloalkyl radicals, with the proviso that at least two of the variables R1, R2, R3 and R4 are substituted or unsubstituted aryl, arylalkyl or arylcycloalkyl radicals, especially substituted or unsubstituted aryl radicals;in an aqueous medium; to produce deformable color and/or effect laminates and dry-paint films.
