Abstract of the Disclosure Photographic elements re protected against the adverse effects resulting from accumulation of static electrical charges by incorporating in the element an artistatic layer formed from an aqueous coating composition containing a water-soluble film- forming polymeric anionic polyelectrolyte in free acid form, a water-soluble film-forming cross-linkable polymeric binder, and an acid-acting cross-linking agent for the polymeric binder. The antistatic layer is useful with both photographic films and photo- graphic papers employed in black-and-white photography or in color photography and will function as an effective anticurl layer as well as providing excellent protection against static. It is durable, abrasion resistant, non-tacky and highly resistant to the aqueous processing baths employed in photographic processing.
