Patent ID: 7141361

Claim:
A thermally developable material that comprises a support having on one side thereof, one or more thermally developable imaging layers comprising a binder and in reactive association, a non-photosensitive source of reducible silver ions, and a reducing agent composition for said non-photosensitive source reducible silver ions, and having disposed on the backside of said support a non-imaging backside conductive layer comprising a conductive metal oxide in one or more binder polymers, and an overcoat layer disposed directly over said backside conductive layer, said overcoat layer comprising one or more film-forming polymers, wherein said backside conductive layer and said overcoat layer have been coated simultaneously out of the same or different organic solvents, the organic solvent used for coating said overcoat layer is an organic solvent mixture comprising an alcohol in an amount of more than 10 and up to 90 weight % of said solvent mixture, wherein the Normalized Average Gap density of said backside conductive layer exhibits an increase of at least 20% over the Normalized Average Gap Density of said backside conductive layer when said organic solvent used for coating said overcoat layer contains no alcohol.
