Abstract

This invention relates to an improvement in a photopolymerizable mixture, comprising a polymeric binder which is soluble or at least swellable in aqueous-alkaline solutions, a compound with at least two acrylic or methacrylic acid ester groups and a boiling point above 100.degree. C. which is capable of addition polymerization, a photoinitiator, and a plasticizer, the improvement being that the plasticizer is a compound corresponding to Formula I ##STR1## wherein R.sub.1 is a hydrogen or halogen atom or an alkyl group with 1 to 4 carbon atoms, R.sub.2 is a hydrogen atom, an OH group, or an alkyl group with 1 to 4 carbon atoms, R.sub.3 is a hydrogen atom or a methyl group, R.sub.4 is an alkyl or alkenyl group with 1 to 20 carbon atoms, and n is zero or a whole number from 1 to 20, and wherein R.sub.4 has at least 4 carbon atoms if n is zero or 1. The invention also relates to a light-sensitive transfer material including the photopolymerizable mixture.
