Abstract

An electrophotographic plate comprises a paper or metal support coated with a dispersion in a resinous binder of a photoconductive polynuclear unsubstituted hydrocarbon containing at least three benzene rings connected to each other by a single carbon-to-carbon bond, for example, p-terphenyl, p-quaterphenyl, p-diphenylbenzene and sexiphenyl. Suitable binders and dye sensitizers are those used in the layers described in Specification 883,782. An exemplary coating composition is described. Specifications 633,849, 772,627, 775,812, 808,485, 811,165, 818,068 and German Specification 853,351 also are referred to.ALSO:A supported layer for use as an electrophotographic plate (see Group XXXVI) comprises, dispersed in a resinous binder, a photo-conductive polynuclear unsubstituted hydrocarbon containing at least three benzene rings connected to each other by a single carbon-to-carbon bond, for example, p-terphenyl, p-quaterphenyl, p-diphenylbenzene, and sexiphenyl. Suitable binders and dye sensitizers are those used in the layers described in Specification 883,782. In an example 64 grams of a silicone resin in the form of a 60% by weight solution in toluene is ball milled with 97 c.c. of toluene and 20 grams of p-diphenyl benzene and then cast on a support. Specifications 633,849, 772,627, 775,812, 808,485, 811,165, 818,068 and German Specification 853,351 also are referred to.
