Color and / or color effect-imparting aqueous coating materials and their use for producing and / or effect, deformable laminates

The invention relates to the use of a copolymer (A) which can be produced by radical polymerisation of a) at least one olefinically unsaturated monomer and b) at least one olefinically unsaturated monomer of general formula (I) R R C=CR R which is different from said olefinically unsaturated monomer (a), the radicals R , R , R and R each representing, independently of each other, hydrogen atoms or substituted or unsubstituted alkyl-, cycloalkyl-, alkylcycloalkyl-, cycloalkylalkyl-, aryl-, alkylaryl-, cycloalkylaryl- arylalkyl- or arylcycloalkyl radicals, on the condition that at least two of the variables R , R , R and R represent substituted or unsubstituted aryl-, arylalkyl- or arylcycloalkyl radicals, especially substituted or unsubstituted aryl radicals; in an aqueous medium, for producing deformable laminates or coating films for imparting a colour and/or effect.
