A photographic element comprising a polymeric film base, a silver halide emulsion layer, and an antistatic layer comprising a colloidal vanadium oxide and a vinyl addition polymer dispersion in a dry weight ratio of from 1:30 to 1:500. The antistatic layer may be present as a backing layer on the side of the base opposite the silver halide emulsion layer, as a subbing layer between the base and the emulsion layer in a single or double side coated photographic element, and/or as a subbing layer between the base and a different backing layer. No barrier layer is used over the antistatic layer.

Photographic element comprising antistatic layer

Light-sensitive photographic element comprising a polymeric film base, a silver halide emulsion layer, and an antistatic layer comprising a low viscosity and highly sulfonated water soluble polyacetal (preferably obtained by reaction of a low viscosity polyvinyl alcohol and a sulfonated aldehyde), a hydrophobic binder selected from the group consisting of a water dispersible sulfopolyester and a latex polymer having hydrophilic functionality, and a polyfunctional aldehyde crosslinking agent. The antistatic layer may be present as a backing layer on the side of the base opposite the silver halide emulsion layer, as a subbing layer between the base and the emulsion layer in a single or double side coated photographic element, and/or as a subbing layer between the base and a different backing layer.
