UV-crosslinkable materials based on (meth)acrylate copolymers contain copolymerized monomers of the general formula I <IMAGE> (I) where R is a certain alkyl radical, an aryl radical or a radical R1 and R1 is a radical <IMAGE> where R2 to R6 are each H, alkyl, a non-ortho OH group, OCH3, OC2H3, SH, SCH3, Cl, F, CN, COOH, COO(C1-C3-alkyl), CF3, N(CH3)2, N(C2H5)2, N(CH3)C6H5, +N(CH3)3X- or +N(CH3)XX-, where X- is an acid anion, and one or more of the radicals R2 to R6 are each a radical <IMAGE> or <IMAGE> or <IMAGE> where Sp is one of the spacer groups of the following type <IMAGE> <IMAGE> and R', R'' and R''' are each H or a certain hydrocarbon, and where the radicals X may be identical or different and are each a divalent, alkylene radical, a cycloalkylene radical or phenylene radical, which are bonded directly to one another and/or are bonded to one another by identical or different groups Y, and Y is a divalent radical from the group consisting of <IMAGE> <IMAGE> and k and m are each from 1 to 10 and 1 and n are each from 0 to 25.
