Abstract
There is described a single phase organic photoconductive composition consisting of a solid solution of N-ethyl-3-tricyanovinylcarbazole and 2,5-bis(N,N-dimethylaminophenyl) oxadiazole in a polycarbonate binder material. The composition exhibits a shallow field dependence for the photogeneration of charge carriers and thus provides a high contrast potential photoconductive system.
Claims6
An organic photoconductive composition consisting essentially of about 3.2 weight percent N-ethyl-3-tricyanovinylcarbazole, about 32.3 weight percent 2,5-bis(N,N-dimethylaminophenyl) oxadiazole and about 64.5% of a polycarbonate resin having recurring structural units represented by the formula ##STR4## where n is in the range of from about 150 to about 400.
