LIGHT-SENSITIVE COMPOSITION FOR ELECTROPHOTOGRAPHIC MATERIAL Russian patent published in 1998 - IPC

Abstract SU 1210584 A1

FIELD: light-sensitive materials. SUBSTANCE: composition containing photoconductive polyimide with general formula , where n= 10-500, x is -CO-, -SO2- or -C(CH3)2, and solvent is distinguished by that, as solvent, pyridine, aniline, N,N-dimethylaniline, or their mixture is used, polyimide concentration being 5-10 wt %. EFFECT: improved quality of material due to increased light sensitivity and/or reduced dark drop of potential and/or by positive or negative charging.
