    • Polymeric photoconductors are disclosed comprising a condensation polymer backbone containing, as repeating units, the condensation residues of (1) a diacid, and (2) an organic difunctional compound capable of undergoing condensation polymerization with said diacid, and an arylamine photoconductor group appended to at least one of said diacid or said organic difunctional compound residues.A preferred polymeric photoconductor is ionic and comprises a condensation copolymer containing, in addition to the above described repeating units, the condensation residue of a second diacid containing an anionic iminodisulfonyl or sulfo group. In certain embodiments, the ionic arylamine-containing polymers are water-dispersible copolyesters.The polymeric photoconductors described are useful in photoconductive compositions and elements. Electrophotographic processes employing such elements are also disclosed.
    • 公开了聚合物光电导体,其包含缩合聚合物主链,其包含(1)二酸的缩合残基作为重复单元,和(2)能够与所述二酸进行缩聚的有机双官能化合物和附在其上的芳基胺感光体基团 所述二酸或所述有机双官能化合物残基中的至少一种。 优选的聚合物光电导体是离子型的,并且包含含有除了上述重复单元之外还含有阴离子亚氨基二磺酰基或磺基的第二二酸的缩合残基的缩合共聚物。 在某些实施方案中,含离子芳基胺的聚合物是水分散性共聚酯。 所述的聚合物光电导体可用于光电导组合物和元素。 还公开了使用这种元件的电子照相方法。
