    摘要： The present invention is a photoconductive element containing an electrically conductive support, an electrical barrier layer disposed over said electrically conductive support and a charge generation layer capable of generating positive charge carriers when exposed to actinic radiation disposed over the barrier layer. The barrier layer is formed from a blocked polyisocyanate containing tetracarbonylbisimide groups. The present invention also discloses a new composition of a blocked polyisocyanate containing tetracarbonylbisimide groups.

    摘要： In a photoconductive element comprising a conductive support, e.g., an electrically conductive film, drum or belt on which a negatively chargeable photoconductive layer is formed, an electrical barrier layer is formed between the support and the photoconductive layer. The barrier layer provides a high energy barrier to the injection of positive charges but transports electrons under an applied electric field. The barrier layer of the invention transports charge by electronic rather than ionic mechanisms and, therefore, is not substantially affected by humidity changes. The barrier layer comprises a polyester-co-imide, polyesterionomer-co-imide or polyamide-co-imide having covalently bonded as repeating units in the polymer chain, aromatic tetracarboxylbisimide groups of the formula: wherein Ar1 and Ar2 represent, respectively, tetravalent and trivalent aromatic groups of 6 to 20 carbon atoms.
