ABSTRACT:
A unitary photoconductive element having an electrically conducting layer, a photoconductive layer thereover, and a multilayer interlayer composition interposed between the conducting layer and the photoconductive layer. The multilayer interlayer composition comprises a layer containing an acidic polymer material, a layer containing a basic polymer material, and an acid-base reaction product zone formed at the interface of the acidic polymer-containing layer and the basic polymer-containing layer. The multilayer interlayer composition provides good adhesion between the conducting and photoconductive layers of the resultant unitary element and can function as an electrical barrier blocking positive charge carriers which might otherwise be injected into the photoconductive layer from the underlying conducting layer.
