Abstract
A photographic element comprising a polyester support and at least one light-sensitive layer on one side of the polyester support, an antistatic layer on the other side of the support, the antistatic layer including a conductive metal oxide in a hydrophilic binder, the antistatic layer being overcoated with a layer containing a cellulose ester binder, and a solvent cast subbing layer disposed between the antistatic layer and the polyester support.
Claims21
A photographic element comprising a polyester support and at least one light-sensitive layer on one side of the polyester support, an antistatic layer on the other side of the support, the antistatic layer including a conductive metal oxide in a hydrophilic binder, the antistatic layer being overcoated with a layer containing a cellulose ester binder, and a solvent cast subbing layer disposed between the antistatic layer and the polyester support, the subbing layer being an addition or condensation polymer.
A method of making a photographic film support having a plurality of backing layers applied thereto which comprises applying a polymeric subbing layer from an organic solvent to a polyester film base, applying an antistatic layer of a conductive metal oxide in a hydrophilic binder to the subbing layer, applying a cellulose ester layer to the antistatic layer.
