| titleOfInvention | Preparation of photoconductive composition |
| abstract | PURPOSE:To improve sensitivity, potential stability during long-term use, and stability of a dispersion fluid by drying a disazo pigment represented by the formula through the freeze-drying method, then, dispersing it and forming it into a film. CONSTITUTION:A photoconductive org. pigment used here is represented by the formula in which R1 is lower alkyl; Ph and Ph' are each optionally substd. phenylene; and X is a residue condensing with a benzene ring to form a naphthalene, anthracene, carbazole, dibenzofuran, or benzocarbazole. This disazo pigment can be easily synthesized by tetrazotizing a corresponding diamine by the normal method, allowing a corresponding coupler to cause azocoupling reaction in the presence of alkali, or once separating said tetrazonium salt of diamine in the form of borofluoride salt or zinc chloride complex salt, or the like, and then, causing the azocoupling reaction with the coupler in a proper solvent. Since the vacuum freeze-drying method is executed in a fixed state of dispersion or soln., fine pulverization of the disazo pigment can be carried out comparatively easily. |
