The invention relates to copolymers made from (a) at least one monomer M1 of formula (I), where R1 stands for an organic group comprising a (meth)acryl group, R2, R3 and R4 stand, independently from one another, for a hydrogen atom or a C1 to C10 alkyl group; and (b) at least one ethylenically unsaturated radical monomer M2 that can be copolymerised, which are different from monomers M1. The invention also relates to two-component adhesives which contain the copolymers and a multifunctional hardener. The copolymers and the two-component adhesives can be used as laminating adhesives.
