Abstract
The present invention relates to photoconductive elements having an electrically conductive support, an electrical barrier layer and, disposed over the barrier layer, a charge generation layer capable of generating positive charge carriers when exposed to actinic radiation. The electrical barrier layer, which restrains injection of positive charge carriers from the conductive support, comprises a crosslinker, a crosslinkable condensation polymer having as a repeating unit a planar, electron-deficient, tetracarbonylbisimide group.
