Synthesis,Characterization and Xerographic Performance of the Triazo Pigments from Tris(4-amino)triphenylamine

As the era for digital printer has come since the 1990s,the investigation into a highly photosensitive charge generator materials(CGM) suitable for IR photoreceptor is concerned.^1-2 This research focuses on the triphenylamine triazo pigments, which exhibit a broad spectral response(450-800mn) and an excellent photosensitivity, especially in the near red-infrared region where solid-state diode laser emit(450-800nm). They are particularly potential CGM for laser printer and digital printer.
