PURPOSE:To obtain a bisazo compound useful as an organic photoconductor used in a high-speed copier, a laser printer, especially, a laminated photoreceptor by coupling a specified tetrazonium salt with a specified coupler. CONSTITUTION:A bisazo compound of formula III (where Y is Cl, methyl or methoxy; R is H, an alkyl, an alkoxy, a halogen or a nitro, n is 1 or 2, and when n=2, R groups may be the same or different) is produced by coupling a tetrazonium salt of formula I (wherein X is an anionic functional group) with a coupler of formula II. This bisazo compound is very useful as an organic photoconductor used for an electrophotographic photoreceptor, especially, a laminated photoreceptor which can show a high sensitivity when used in a high-speed copier or a laser printer. |
