Abstract

PURPOSE: To prepare a disazo cpd. with a specified crystal form, excellent in heat resistance and mechanical property, by the reaction of a tetradiazonium salt with a specified cpd. in an org. solvent.
CONSTITUTION: A tetradiazonium salt of formula I (wherein X is an anionic functional group) obtd. from 3,6-diamino-9-ethylcarbazole by disazotization in an inorg. solvent followed by isolation in the form of, e.q., a fluoroborate, is reacted with a cpd. of formula II in an org. solvent at 0W20°C for 0.5W3hr, to obtain an α type disazo cpd. of formula III having X-ray diffraction of the figure showing intense diffraction at angles of diffraction 2θ° (Cu-Kα) of about 4.8°, 6.9°, 7.7°, 10.1°, 10.9° and 25.8°. Then an electrophotographic sensitized material is obtd. by providing a photosensitized layer comprising said diazo cpd. and a resin binder on a conductive support.
