| 摘要 |
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<1>R<2>C=CR<3>R<4> which is different from said olefinically unsaturated monomer (a), the radicals R<1>, R<2>, R<3> and R<4> 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<1>, R<2>, R<3> and R<4> 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.
