@ Disclosed in a photosensitive material for the electrophotography, which comprises a dispersion of a charge-generating pigment in a charge-transporting medium composed mainly of a polyvinyl carbazole resin, wherein a perylene pigment represented by the following general formula:
wherein R, and R2 stand for a hydrogen atom or a substituted or unsubstituted alkyl or aryl group, is dispersed and incorporated as the charge-generating pigment in an amount of 1 to 40 parts by weight per 100 parts by weight of the polyvinyl carbazole resin and a halogeno-p-benzoquinone is further incorporated in an amount of 1 to 60 parts by weight per 100 parts by weight of the polyvinyl carbazole resin.
@公开了一种用于电致发光的感光材料,它包括电荷发生颜料在主要由聚乙烯基咔唑树脂构成的电荷传输介质中的分散体,其中由以下通式表示的过烯烃颜料:
其中 R 和 R2 代表氢原子或取代或未取代的烷基或芳基,作为电荷发生颜料以每 100 份聚乙烯基咔唑树脂 1 至 40 份(重量比)的量分散和掺入,卤代对苯醌以每 100 份聚乙烯基咔唑树脂 1 至 60 份(重量比)的量进一步掺入。
