Abstract
Abstract A photopolymerizable composition which contains one or more olefinically unsaturated compounds and from 0.2 to 20% by weight (based on the unsaturated compound(s)) of a photoinitiator, with or without conventional additives, the photoinitiator being a mixture of one or more aromatic carbonyl compounds of the general formula (A) ##STR1## where Ar is an ortho-arylene radical which may or may not be substituted by one or more radicals R 1 to R 4 , R 1 , R 2 , R 3 and R 4 are identical or different and each is H, alkyl or 1 to 5 carbon atoms, phenyl, halogen, alkoxy of 1 to 5 carbon atoms, alkaryl of 7 to 11 carbon atoms, aralkyl of 7 to 11 carbon atoms or --CO 2 R 9 , where R 9 is alkyl of 1 to 5 carbon atoms, and n is 0 or 1, and an amine, with or without an aromatic carbonyl compound which differs from (A). This photopolymerizable composition is particularly suitable for the manufacture of photopolymer printing plates and UV-curing printing inks.
