ABSTRACT:
A composite support for an imaging element is described, which composite support comprises a polymeric film and an electrically conductive layer, wherein the polymeric film comprises a surface which has been activated by energetic treatment, the electrically conductive layer comprises an electrically conductive agent dispersed in an aqueous dispersible polymeric binder comprising an aliphatic, anionic polyurethane having an ultimate elongation to break of at least 350 percent, and the electrically conductive layer is in contiguous contact with the activated surface of the polymeric film. Imaging elements for use in an image-forming process are also described, which element comprise such composite supports and at least one image-forming layer. The invention provides composite supports and imaging elements containing an electrically conductive antistatic layer having excellent adhesion to energetic surface-treated polymer film supports, and of auxiliary layers to the electrically conductive antistatic layer.
