More Information
Summary:A photopolymerizable mixture is described comprising (a) a polymeric binder, (b) an acrylate or alkacrylate of a polyhydric alcohol, said compound 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, (d) a second photoinitiator comprising a trihalomethyl compound capable of being cleaved by irradiation, and (e) a third photoinitiator comprising an acridine, phenazine or quinoxaline compound. The mixture is suitable for the production of printing plates and photoresists and displays increased photosensitivity.
