Abstract
A photographic element is disclosed comprising a support bearing at least one photosensitive layer and an antistatic layer comprising a binder, vanadium pentoxide, and an aromatic ketone ultraviolet absorbing compound. The antistatic layer provides the properties of UV absorbance and antistatic protection, which properties are retained after photographic processing. Specifically, in accordance with preferred embodiments, a layer providing a surface and volume resistivity of less than about 10.sup.8 ohm/cm coupled with an optical density of greater than about 1.0 from 300-400 nm and less than about 0.03 as measured in orthochromatic light is provided. The layer composition components are soluble in common coating solvents, compatible with each other, and do not produce any adverse sensitometric effects either in the raw state, during or after processing of the film itself.
