Uv-crosslinkable materials based on (meth) acrylate polymers

Abstract From the Canadian patent

UV-crosslinkable materials, based on (meth)acrylate copolymers contain copolymerized monomers of the general formula I, (see formula I) where R is a certain alkyl radical, an aryl radical or a radical R1 and R1 is a radical, (see formula II) where R2 to R5 are each H, alkyl, a non-ortho OH croup OCH3, OC2H3, SH, SCH3, Cl, F, CN, COOH COO(C1-C3-alkyl), CF3, N(CH3)2, N(C2H5)2 N(CH3)C8H5, +N(CH3)3X- or +N(CH3)2X-, where X- is an acid anion and one or more of the radicals, R2 to R6 are each a radical (see formula III) , or, (see formula IV) or, (see formula V), ) , where Sp is one of the spacer groups of the following type, (see formula VI, VII), and, R', R'' and R''' are each H or a certain …
