Abstract

Photopolymerizable mixtures comprising one or more photopolymerizable, olefinically unsaturated compounds and one or more photoinitiators or photosensitizers, with or without other conventional additives and/or assistants, contain, as an activator, a tertiary amine of the general formula (I) ##STR1## wherein R.sup.1 and R.sup.2 are each an unsubstituted alkyl, cycloalkyl or phenyl radical, hydroxyl or alkoxy, or R.sup.1 and R.sup.2 are bonded together to form a cyclic alkylene radical, R.sup.3 has the same meanings as R.sup.1 or R.sup.2 and may furthermore be hydrogen, acyloxy or substituted benzoyloxy, and R.sup.4 and R.sup.5 are each an unsubstituted or substituted alkyl, cycloalkyl or phenyl radical, or R.sup.4 and R.sup.5 are bonded together to form a cyclic alkylene or alkyleneoxyalkylene radical.
