| titleOfInvention | Novel tetrazonium salt compound, novel disazo compound and its preparation |
| abstract | NEW MATERIAL:A tetrazonium salt compound shown by the formula I (Y is anionic functional group) or a disazo compound shown by the formula II (X is aromatic ring, or hetero ring; Ar is aromatic ring, or hetero ring). n USE: A tetrazonium salt compound is useful as an intermediate for disazo compounds. The disazo compounds are useful as photoelectric materials for sensitized materials for electrophotography, especially as charge-generating materials. Since a laminate type sensitized material has a photosensitive wavelength band in about 450W600nm at short wave side of visible light range, it has improved reproducibility of reprography image of red manuscript. n PROCESS: 1,5-Diaminoanthraquinone shown by the formula III is diazotized with sodium nitrite in an inorganic acid to give a tetrazonium salt shown by the formula I . This compound is reacted with a coupler shown by the formula IV at -10W40°C, to give a disazo compound shown by the formula II. n COPYRIGHT: (C)1984,JPO&Japio |
