Beschreibung
Zusammenfassung:	A photopolymerisable mixture is described which contains, as essential constituents, a) a polymeric binder, b) an acrylate ester or alkacrylate ester of a polyhydric alcohol with at least one group which is photooxidisable on exposure in the presence of a photoreducible dye, but no urethane group, c) a photoreducible benzoxanthene dye or benzothioxanthene dye as a photoinitiator, d) a radiation-cleavable trihalogenomethyl compound and e) an acridine compound or phenazine compound active as a photoinitiator. The mixture is suitable for producing printing plates and photoresists and is distinguished by increased photosensitivity.
