ABSTRACT:
This application describes a multilayer electrophotographic element composed of a conducting layer, a photoconductive layer, and a polymeric interlayer having a surface resistivity greater than about 10.sup.12 ohm/sq. between the conducting layer and the photoconductive layer. The interlayer comprises a blend of at least two distinct polymeric phases comprising: (a) a film-forming, water- or alkali-soluble polymer, and (b) a film-forming hydrophobic polymer.
