Abstract

A photopolymerizable composition is described comprising (a) a polymeric binder, (b) an acrylate or alkacrylate of a polyhydric alcohol, said acrylate or alkacrylate being free of urethane groups and further comprising at least one group which is photooxidizable on exposure to actinic radiation in the presence of a photoreducible dye, (c) a photoinitiator comprising a photoreducible dye, and (d) a second photoinitiator comprising a trihalomethyl compound capable of being cleaved by irradiation. The composition is suitable for production of printing plates and photoresists and displays increased photosensitivity.
