Element having improved adhesion of auxiliary layers to film supports containing antistatic layers

Claim 1

A photographic element comprising: (A) a polymeric film support having carboxyl groups attached to the surface thereof; (B) a photosensitive layer coated on one side of the support; (C) a permanent antistatic layer coated directly on the surface of the support opposite the photosensitive layer, said antistatic layer consisting essentially of the reaction product of: (1) a water-soluble, electrically conductive polymer having functionally attached carboxyl groups integral to the polymer, and (2) a polyfunctional substituted aziridine wherein at least one hydrogen atom on a carbon atom of the aziridine ring is substituted with an alkyl substituent wherein alkyl is of 1 to 6 carbon atoms, wherein the aziridine interlinks the water-soluble, electrically conductive polymer having functionally attached carboxyl groups integral to the polymer and the carboxyl groups on the surface of the support to form an antistatic layer; and (D) an auxiliary layer coated over said antistatic layer, said auxiliary layer consisting essentially of an aqueous dispersion of gelatin, a gelatin crosslinking agent, and an adhesion promoting amount of an adhesion agent selected from the group consisting of 1) a compound containing at least one --NH 2 group, 2) a compound containing at least two --NH groups, and 3) mixtures thereof, wherein said adhesion agent is sufficiently soluble in water that said adhesion promoting amount of adhesion agent may be dissolved in the dispersion used to coat said auxiliary layer, with the proviso that said adhesion agent is not malonamide.
