Alkoxyphenyl-substituted bisacylphosphine oxides of the formula I in which R1 and R2 are identical or different and are a radical of the formula II n which R4 and R5 independently of one another are C1-C12alkyl or C1-C12alkoxy, R6, R7 and R8 independently of one another are hydrogen, C1-C12alkyl, C1-C12alkoxy or halogen, and R3 is a radical of the formula III in which R9 through R12 are hydrogen, halogen, alkyl or alkoxy, are suitable for the photopolymerization of compounds containing ethylenically unsaturated double bonds. |
