Copolymers based on dicarboximides, alkenyl isocyanates and/or alkenylurethanes

A copolymer based on monomers selected from the group consisting of dicarboximides, alkenyl isocyanates and alkenylurethanes of the formula I ##STR22## where R.sup.1, R.sup.2, R.sup.3, R.sup.4 and R.sup.5, independently of one another are each selected from the group consisting of hydrogen, C.sub.1 -C.sub.20 -alkyl, C.sub.1 -C.sub.20 -alkyl which contains hetero atoms and substituted C.sub.1 -C.sub.20 -alkyl;

• R.sup.6 is hydrogen or C.sub.1 -C.sub.10 -alkyl which is unsubstituted or substituted by phenyl or hydroxyl, or is C.sub.3 -C.sub.8 -cycloalkyl, or is phenyl or benzyl, each of which is unsubstituted or substituted by 1 to 4 C.sub.1 -C.sub.6 -alkyl or C.sub.1 -C.sub.6 -alkoxy groups, or is phenethyl, diphenylmethyl, naphthyl, carbazoyl, isobornyl, adamantyl or 9-fluorenyl;
• X is O or NH;
• Y is methylene, ethylene, propylene, isopropylene, straight-chain or branched C.sub.1 -C.sub.20 -alkylene, ##STR23## where n is from 1 to 15, Z is hydrogen or a radical of formula V ##STR24## where R.sup.7 to R.sup.10 are identical or different and are each H, straight-chain or branched C.sub.1 -C.sub.10 -alkyl, C.sub.1 -C.sub.10 -alkoxy or C.sub.3 -C.sub.7 cycloalkyl,
• I is O or NR.sup.11,
• R.sup.11 is H, C.sub.1 -C.sub.10 -alkyl, C.sub.3 -C.sub.7 -cycloalkyl, phenyl, benzyl or phenethyl,
• u and v are each.0 or 1,

• E is a radical of a diazo component which is derived from a five-membered aromatic heterocyclic amine which has from one to three hetero atoms selected from the group consisting of nitrogen, oxygen and sulfur in the heterocyclic ring and may be fused with a benzene, thiophene, pyridine or pyrimidine ring;
• M is any copolymerizable monomer and a+b+c+d=1, where
• a and c each range from 0.3 to 0.7 and
• b and d each range from 0 to 0.3.
