ABSTRACT:
Disclosed is a printing plate, for an electrophotographic process, which comprises an electroconductive support and a photosensitive layer formed on the electroconductive support, in which the photosensitive layer is formed by incorporating (a) a trisazo pigment represented by the general formula (I) and (b) at least one member selected from perynone pigments and anthanthrone pigments as photoconductive substances and (c) at least one electron donor substance as a sensitizer in an alkali-soluble binder resin. This printing plate has a high sensitivity and a printing image having a high quality is formed on the printing plate without contamination of the non-image area due to the electrophotography, and prints having a high-quality image can be obtained by using this printing plate.
