Abstract:
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. Also a process for making an element having antistatic properties.
