Abstract

An electrophotographic plate comprises a paper or metal support coated with a dispersion in a resinous binder of a photo-conductive heterocyclic compound containing at least two benzenoid rings and which may be substituted for example, by one or more similar or different substituents from the following:- a halogen atom, an amino, hydroxy, nitroalkyl, acyl or aryl group. Examples of such compounds are anthrapyridone, anthrapyrimidone, anthrapyrimidine, N-methylanthrapyrimidone, 4-bromo-N-methylanthra-pyridone, 4-amino-N-methylanthrapyridone, 5-aminoanthrapyrimidine and 4-p-toluidino-N-methylanthrapyridone. Suitable binders and dye sensitizers are those used in the layers p described in Specification 883,782. An exemplary coating composition is described in detail. Specifications 633,849, 772,627, 775,812, 808,485, 811,165 and 818,068 also are referred to.ALSO:A supported layer for use as an electrophotographic plate (see Group XXXVI) comprises, dispersed in a resinous binder, a photoconductive heterocyclic compound containing at least two benzenoid rings and which may be substituted, for example, by one or more similar or different substituents from the following:- a halogen atom, an amino, hydroxy, nitroalkyl, acyl or aryl group. Examples of such compounds are anthrapyridone, anthrapyrimidone, anthrapyrimidine, N-methylanthrapyrimidone, 4-bromo-N-methyl-anthrapyridone, 4-amino-N-methylanthrapyridone, 5-aminoanthrapyrimidine, and 4-p-toluidino-N-methylanthrapyridone. 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% solution in toluene is ball-milled with 97 c.c. of toluene, and 20 grams of anthrapyrimidone and then cast on a support. Specifications 633,849, 772,627, 775,812, 808,485, 811,165 and 818,068 also are referred to.
