Abstract

Alkyl-bisacylphosphinoxides. Compounds of formula I < IMAGE > in which R1 denotes alkyl with 1 to 18 carbon atoms, cyclopentyl or cyclohexide, and R2 and R3 independently of each other denote phenyl unsubstituted or substituted from one to four times with halogen, alkyl with 1 to 4 carbon atoms and/or alkoxyl with 1 to 4 carbon atoms, provided that when R2 and R3 denote phenyl substituted with chlorine, R1 is not decyl. They are suitable for the photopolymerization of compounds with ethylenically unsaturated double bonds.
