Abstract
The use of a copolymer (A) preparable by free-radical polymerization of
a) at least one olefinically unsaturated monomer and
b) at least one olefinically unsaturated monomer different than the olefinically unsaturated monomer (a) and of the general formula 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 are substituted or unsubstituted aryl, arylalkyl or arylcycloalkyl radicals, especially substituted or unsubstituted aryl radicals; in an aqueous medium, in a clearcoat material used to produce clearcoats KL and multicoat color and/or effect coating systems ML.
