Abstract

UV-crosslinkable materials based on (meth)acrylate copolymers and containing from 0.01 to 10% by weight, based on the copolymer, of copolymerized monomers of the formula I ##STR1## where x is alkyl of 1 to 3 carbon atoms or is phenyl which is unsubstituted or substituted by n Y groups, Y is --H, --CF.sub.3, --O-- alkyl and/or alkyl-COO--, where alkyl in each case is of 1 to 4 carbon atoms, halogen, --CH, --COOH or a non-ortho --OH group, n is from 0 to 4 and Z is a group of the formula ##STR2## where R is H or C.sub.1 -C.sub.4 -alkyl and A is an alkylene, oxaalkylene or polyoxaalkylene radical of 2 to 12 carbon atoms are used as hotmelt adhesives, for coating sheet-like mineral substrates and as surface coatings.
