Abstract
NEW MATERIAL:A disazo compound of formula I [A is group of formula II or III (R is H, Cl, Br, methyl, ethyl, methoxy, ethoxy, nitro, dimethylamino, diethylamino, or phenyl; n is 1 or 2)].
EXAMPLE: The compound of formula IV.
USE: A photoconductive material for electrophotography, having excellent mechanical strength, flexibility, and photosensitivity.
PROCESS: The exemplified compound can be obtained e.g. by (1) dissolving a compound of formula V [i.e. N,N'-bis(2-hydroxy-3-naphthoyl)-4,4'-diamino-3,3'- dichloro-diphenylmethane] and a compound of formula VI or formula VII (X is anionic functional group), e.g. benzenediasonium tetrafluoroborate, in a solvent e.g. dimethyl formamide, (2) adding aqueous solution of sodium acetate dropwise to the solution, and (3) filtering off the precipitate.
