Novel compounds of the formula I or II STR1 are described, in which M1 and M2 individually are --OH or together are --O--, R is hydrogen, C1-20 -alkyl, C2-5 -alkenyl, C3-5 -alkynyl, C5-12 -cycloalkyl, benzyl, phenyl or toluyl, X is --NO2, --OR', --SR' or --SO2 R' and the (R')s independently of one another are C1-20 -alkyl, C3-5 -alkenyl, C3-5 -alkynyl, C2-4 -monohydroxyalkyl, C1-12 -halogenoalkyl, benzyl, C5-12 -cycloalkyl, phenyl, carboxyphenyl, halogenophenyl, nitrophenyl, alkyl- or alkoxy-phenyl each having 1-4 C atoms in the alkyl or alkoxy moieties, or acetylaminophenyl. The compounds (I) and compounds (II) in which M1 and M2 together are --O-- are suitable as sensitizers for photocrosslinkable polymers or as initiators for the photopolymerization of ethylenically unsaturated compounds or for the photochemical crosslinking of polyolefins.
