Abstract

Coating compositions hardenable by ionizing radiation comprising as binding agents a mixture of PA1 A. at least 1 unsaturated olefin compound containing urethane groups, and PA1 B. at least 1 further unsaturated olefin compound that may be copolymerized, Characterized in that the unsaturated olefin compound (A) containing the urethane groups is a reaction product of PA2 A. a compound of the general formula ##EQU1## WHERE N IS 1 OR 2, WHERE R stands for a straigt chain or branched alkyl group of valence n, Where R.sub.1 is hydrogen, methyl or the group ##EQU2## where R.sub.3 is a monovalent alkyl residue and WHERE R.sub.2 is hydrogen or methyl, and PA2 B. a compound containing at least 1 isocyanate group where the mixture of (A) and (B) may contain conventional additives of the lacquer industry.
