ABSTRACT:
Novel compounds of the formula I or II ##STR1## are described, in which M.sub.1 and M.sub.2 individually are --OH or together are --O--, R is hydrogen, C.sub.1-20 -alkyl, C.sub.2-5 -alkenyl, C.sub.3-5 -alkynyl, C.sub.5-12 -cycloalkyl, benzyl, phenyl or toluyl, X is --NO.sub.2, --OR', --SR' or --SO.sub.2 R' and the (R')s independently of one another are C.sub.1-20 -alkyl, C.sub.3-5 -alkenyl, C.sub.3-5 -alkynyl, C.sub.2-4 -monohydroxyalkyl, C.sub.1-12 -halogenoalkyl, benzyl, C.sub.5-12 -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 M.sub.1 and M.sub.2 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.
