Compounds of the general formula I STR1 wherein Z is CR1 R2 (OR3) or phenyl, R1 being H, C1-6 -alkyl or phenyl, R2 being H, C1-6 -alkyl or C1-6 -alkoxy and R3 being H, C1-6 -alkyl or C1-6 -alkanoyl and Z' is Y--[(CH2)m --X]n --, X being CH2 or 0, Y being OH; COOH or SO3 H including the alkali metal, alkaline earth metal or ammonium salts thereof and also the salts thereof with organic nitrogen bases; or NRR' in which R and R' are in each case H, C1-20 -alkyl or C1-4 -hydroxyalkyl, if appropriate quaternized or in the form of the acid addition salts, and n and m each being the numbers 1-4, are excellently suitable as photoinitiators for the photopolymerization of ethylenically unsaturated compounds, in particular in aqueous systems.

Acyl 1-acetoxy-2-phenoxyethanes Ia-Id were prepared by aluminium chloride or polyphosphoric acid-catalyzed Friedel-Crafts acylation.Subsequent hydrolysis gave the corresponding alcohols IIa-IId.The formation of ortho-isomers during acylation was not observed.
