ABSTRACT:
Photoconductive compositions containing aromatic sulfonyl fluorides are novel compositions which are useful in electrophotographic processes, such as xerography. E.g., an electrostatic copying paper is obtained by coating an electroconductive base paper with a composition comprising poly(N-vinylcarbazole) and 4,4'-biphenyldisulfonyl fluoride.
