UV-crosslinkable materials based on (meth)acrylate polymers
First Claim
1. A UV-crosslinkable material comprising a copolymer of (i) an ester of (meth)acrylic acid and a C1 -C24 alkanol, having a K value of from 10 to 150, and (ii) from 0.01 to 20% by weight, based on the copolymer, of at least one copolymerized monomer of the formula I ##STR26## where R is a straight-chain alkyl of 1 to 3 carbon atoms, branched, unsubstituted or substituted alkyl of 3 to 4 carbon atoms, aryl or a radical R1 andR1 is a radical ##STR27## where R2 to R6 are identical or different and are each H, aryl of 1 to 4 carbon atoms, a non-ortho OH group, OCH3, OC2 H5, SH, SCH3, CL, F, CN, COOH, COO(C1 -C3 -alkyl), CF3, N(CH3)2, N(C2 H5)2, N(CH3)C6 C5, + N(CH3)3 X-, or + N(CH3)2 X-, where X- is an acid anion, eg. Cl-, Br-, acetate, HSO4-, H2 PO4- or NO3- and one or more of the radicals R2 to R6 are a radical ##STR28## where Sp is one of the spacer groups of the following type ##STR29## and R'"'"' is H, C1 -C4 -alkyl or phenyl,R" is H or C1 -C4 -alkyl andR"'"'"' is H or CH3and where the radicals X may be identical or different and are each a divalent, unsubstituted or substituted alkylene radical which may be perfluorinated, an unsubstituted or substituted cycloalkylene radical of 5 to 10 carbon atoms or an unsubstituted or substituted o-, m- or p-phenylene radical, which are bonded directly to one another and/or are bonded to one another by idential or different groups Y, and Y is a divalent radical from the group consisting of ##STR30## k and m are each from 1 to 10 and l and n are each from 0 to 25.

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 R1 and R1 is a radical ##STR2## where R2 to R6 are each H, alkyl, a non-ortho OH group, OCH3, OC2 H3, SH, SCH3, Cl, F, CN, COOH, COO(C1 -C3 -alkyl), CF3, N(CH3)2, N(C2 H5)2, N(CH3)C6 H5, + N(CH3)3 X- or +N(CH3)X X-, where X- is an acid anion, and one or more of the radicals R2 to R6 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.
