ABSTRACT OF THE DISCLOSURE: The invention is concerned with an acylphosphine oxide of the formula (I) Image (I) where R1 is straight-chain or branched alkyl of 1 to 6 carbon atoms, cyclohexyl, cyclopentyl, phenyl, or naphthyl which are unsubstituted or substituted by halogen, alkyl of 1 to 6 carbon atoms or alkoxy of 1 to 6 carbon atoms, or a S-containing or N- containing five-membered or six-membered aromatic heterocyclic radical having one heteroatom; R2 has one of the meaning of R1, but R1 and R2 may be identical or different, or is alkoxy of 1 to 6 carbon atoms, phenoxy, methylphenoxy, benzyloxy or vinyloxy, or R1 and R2 may be joined together to form an acylphosphonic acid o-phenylene ester; and R3 is straight-chain or branched alkyl of 2 to 18 carbon atoms, an .alpha.-acyloxyethyl . .beta.-carboxyethyl radical, a cycloaliphatic radical of 3 to 12 carbon atoms, a vinyl, a methylvinyl, a naphthyl radical, a phenyl or naphthyl which are substituted by an alkyl of 1 to 8 carbon atoms or by thioalkoxy of 1 to 6 carbon atoms, a phenyl or naphthyl which are substituted by an alkoxy of 1 to 6 carbon atoms, or a S-containing or N- containing five-membered or six-membered aromatic heterocyclic radical having one heteroatom,or is the group: Image whera R1 and R2 have the above meanings and X is phenylene or an aliphatic or cycloaliphatic divalent radical of 2 to 6 carbon atoms, with the proviso that R1 and R2 do not simultaneously stand for alkyl of 1 to 6 carbon atoms if R3 is an alkoxy substituted phenyl and with the further proviso that R1 is not t-butyl or benzyl if R3 stands for t-butyl or n-butyl. This invention also concerned the process for the preparation of these acylphosphine oxide compounds from acid halides of the general formula Image where X is chlorine or bromine, and a phosphine of the general formula Image and the use of the acylphosphine oxides as photoinitiators in photopolymerizable compositions.
