Abstract

PURPOSE:To obtain a wide range of disazo compds. effective in a laminate type photosensitive body by using the combination of a specified tetraazonium salt compd. with a proper coupler. CONSTITUTION:The tetraazonium salt compd. represented by formula I, X being an anionic functional group, in a useful intermediate compd. of the disazo compd., and a wide range of disazo compds. having a benzophenone structure and azo groups at the 3- and 3'-positions can be synthesized by combining said tetraazonium compd. with proper couplers. These disazo compds. can be used for the photoconductive material of the electrophotographic sensitive body, especially, for its carrier generating material. The tetraazonium salt of formula I is obtained, e.g., by reducing 4,4'-dichloro-3,3'-dinitrobenzophenone to produce 4,4'-dichloro-3,3'-diaminobenzophenone, and diazotizing it.

BACKGROUND ART It has been known that certain disazo compounds are effective as charge-generating pigments used in charge-generating layers of laminated photoreceptors, which are one form of electrophotographic photoreceptors. The laminated photoreceptor referred to herein means that a charge-generating pigment having the ability to generate charge carriers by light is applied onto a conductive support by an appropriate method such as vacuum evaporation, coating with a pigment solution, or adding a pigment to a resin solution. Charge transport is a method in which charge carriers generated in the charge generation layer can be efficiently injected onto the charge generation layer by coating a dispersion liquid containing fine particles dispersed therein, and the charge carriers generated in the charge generation layer can be efficiently transferred. It is a photoreceptor on which a charge transporting layer is formed (usually this charge transporting layer consists of a charge transporting substance and a binder resin).
