Copolymers (A) containing lateral, primary and/or secondary carbamate groups (a12) and groups (a31) which can be activated with actinic radiation, preparable by I. in a first process step copolymerizing (a1) a monomer containing (a11) a group of the general formula I: <?in-line-formulae description="In-line Formulae" end="lead"?>CH<SUB>2</SUB>-C(R)C(O)-O-, (I)<?in-line-formulae description="In-line Formulae" end="tail"?> in which the variable R is a hydrogen atom, a halogen atom, a nitrile group or an alkyl group having 1 to 10 carbon atoms, and (a12) a primary and/or secondary carbamate group, and (a2) a monomer containing (a21) a free-radically or ironically polymerizable, olefinically unsaturated double bond and (a22) a reactive functional group which is not reactive with the carbamate groups (a12) and is not polymerizable with the double bond (a21), to give the copolymer (a1/a2), and II. in a further process step, reacting the copolymer (a1/a2) with (a3) a compound containing (a31) a group which can be activated with actinic radiation and (a32) a reactive functional group complementary to the reactive functional group (a22), to give the copolymer (A); processes for preparing them, and their use.
