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