ABSTRACT:
An electrophotographic recording material is disclosed that comprises an electrically conducting layer support being in particular suitable for the production of printing plates or printed circuits, and a photoconductive layer comprising an organic photoconductor, a phenolic resin as the binder, a sensitizer and customary additives. The binder employed is an optionally substituted polyvinylphenol which has a molecular weight (weight average) of preferably between 1,500 and 60,000. The polyvinylphenol may be halogenated, preferably brominated. Furthermore, an o-quinonediazide may be contained in the photoconductive layer. The recording material is distinguished by a high charging capacity, good photosensitivity and excellent solubility properties. It is suitable for the reproduction of fine image elements.
