Abstract

NEW MATERIAL:Dis-azo compound of formula I.
USE: Dis-azo pigment which is highly sensitive and effective as an electric charge-generating pigment used in the electric charge-generating layer of a lamination type photosensitive material used in an electrophotography system.
PREPARATION: 2,7-Diamino-9-fluorenone of formula II is diazotized, and then the reaction product is reacted with 2-hydroxy-3-(2-chlorophenylcarbamoyl)-naphthalene of formula III to produce the desired compound.
