Abstract

Compounds of the general formula I ##STR1## are described in which R.sup.1 is a group of the formula ##STR2## and R.sup.2 is a hydrogen atom or a methyl group, or PA1 R.sup.1 and R.sup.2 jointly form an optionally substituted 5- or 6-membered ring, PA1 R.sup.3 is a hydrogen atom, a methyl group or an optionally substituted phenyl group, PA1 R.sup.4 is a hydrogen or halogen atom, a methyl group, an optionally substituted benzoyl group or a group of the formula ##STR3## n is zero or 1, X is a hydrogen or chlorine atom, an alkyl group containing 1 to 4 carbon atoms or one of the groups OA, CH.sub.2 OA, CH.sub.2 NHA or C.sub.2 H.sub.4 OA, and PA1 A is an acryloyl or methacryloyl group, the compounds containing in each case at least one group A. The compounds are suitable for the production of photoresists and printing plates as diffusion-resistant photoinitiators in photopolymerizable mixtures.
