ABSTRACT:
Compounds of the formula I ##STR1## in which R.sub.1 is C.sub.1 -C.sub.18 alkyl, cyclopentyl or cyclohexyl, and R.sub.2 and R.sub.3, independently of one another, are phenyl which is unsubstituted or monosubstituted to tetrasubstituted by halogen, C.sub.1 -C.sub.4 alkyl and/or C.sub.1 -C.sub.4 alkoxy, with the proviso that R.sub.1 is not decyl if R.sub.2 and R.sub.3 are chlorine-substituted phenyl, are suitable for the photopolymerisation of compounds containing ethylenically unsaturated double bonds.
