Abstract

Copolymers are composed of a) from 0.01 to 40% by weight of a copolymerized ethylenically unsaturated compound having at least one isocyanate group blocked with an oxime, b) from 30 to 99.99% by weight of at least one C.sub.1 -C.sub.20 -alkyl (meth)acrylate, one vinyl ester of carboxylic acids of 1 to 20 carbon atoms, one vinylaromatic of up to 20 carbon atoms, one ethylenically unsaturated nitrile of 3 to 6 carbon atoms, one vinyl halide or one nonaromatic hydrocarbon of 4 to 8 carbon atoms having at least 2 conjugated double bonds, c) from 0 to 30% by weight of at least one comonomer having at least one keto or aldehyde group and d) from 0 to 50% by weight of at least one further monomer.
