ABSTRACT:
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.
