Zusammenfassung:Polymers capable of being cross-linked by light, which comprise units having lateral substituted 1-carbonyloxy-1H-naphthalene-2-one groups of the formula WHERE R is hydrogen or methyl; R1 is a streight-chain or branched, saturated or unsaturated hydrocarbon radical having from 1 to 3 carbon atoms, in which a hydrogen atom may be substituted by cyano, (C1 to C2) alkoxy, carbo-(C1 to C2)-alkoxy, (C1 to C2)acyl or (C1 to C2)acyloxy and R2 and R3, independently, each are (C1 to C4)alkyl or chlorine; and R4 is (C1 to C4)alkyl, nitro, chlorine or bromine, are provided.
