Abstract

Compounds of the formula I, II, III, IV or V ##STR1## in which Ar, X, Y, Y', R.sup.1 to R.sup.5 and R.sup.1' to R.sup.5' are as defined in claim 1, can be used as photoinitiators for the photopolymerization of unsaturated compounds. They can be prepared by a Diels-Alder reaction and/or a Grignard reaction.
