Abstract

Curable coating compositions which contain, as the binder, one or more olefinically unsaturated compounds containing urethane groups, with or without one or more olefinically unsaturated compounds copolymerizable therewith, in which the olefinically unsaturated compound containing urethane groups is a reaction product of vinyl isocyanate and a compound which contains at least one hydroxyl group and at least one radical of an ester of an .alpha.,.beta.-olefinically unsaturated carboxylic acid of 3 to 6 carbon atoms. The compositions may, for example, be used for the manufacture of coatings which can be cured with electron beams.
