Abstract

UV-crosslinkable materials based on (meth)acrylate copolymers contain copolymerized monomers of the general formula I ##STR1## where R is a certain alkyl radical, an aryl radical or a radical R.sup.1 and R.sup.1 is a radical ##STR2## where R.sup.2 to R.sup.6 are each H, alkyl, a non-ortho OH group, OCH.sub.3, OC.sub.2 H.sub.3, SH, SCH.sub.3, Cl, F, CN, COOH, COO(C.sub.1 -C.sub.3 -alkyl), CF.sub.3, N(CH.sub.3).sub.2, N(C.sub.2 H.sub.5).sub.2, N(CH.sub.3)C.sub.6 H.sub.5, .sup.+ N(CH.sub.3).sub.3 X.sup.- or .sup.+N(CH.sub.3).sub.X X.sup.-, where X.sup.- is an acid anion, and one or more of the radicals R.sup.2 to R.sup.6 are each a radical ##STR3## where Sp is one of the spacer groups of the following type ##STR4## 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 ##STR5## and k and m are each from 1 to 10 and 1 and n are each from 0 to 25.
