Abstract

The present invention relates to urethane acrylates, which may be cured with high-energy radiation, in which the urethane acrylates are the reaction product of a) a polyisocyanate component containing 20 to 100 mole %, based on the moles of the polyisocyanate component a), of iminooxadiazine dione group-containing polyisocyanate trimers corresponding to formula A ##STR1## wherein R.sup.1, R.sup.2 and R.sup.3 are the same or different and represent linear or branched, C.sub.4 -C.sub.20 (cyclo)alkyl groups and X is the same or different and represents isocyanate groups or isocyanate group-containing radicals that also contain iminooxadiazine dione, isocyanurate, uretdione, urethane, allophanate, biuret or oxadiazine trione groups, wherein R.sup.1, R.sup.2 and R.sup.3 are attached to a nitrogen atom, with b) an alcohol component containing at least one monobasic, hydroxy-functional, linear or branched C.sub.1 -C.sub.12 alkyl ester of (meth)acrylic acid. The present invention further relates to the use of the urethane acrylates as binder components for coating compositions that are curable with high-energy radiation.
