Patent number: 6479228Abstract: The present invention can relate to an imaging element including a support, an image-forming layer superposed on the support, and an outermost scratch resistant antistatic layer superposed on the support. The scratch resistant layer may include a polymer having a modulus greater than 100 MPa measured at 20° C., a filler particle with the proviso that the filler particle is not an electronically conductive crystalline metal oxide or a compound oxide thereof, and an electronically conducting polymer. The volume ratio of the polymer to the filler particle may be between 70:30 and 40:60 and the electronically conducting polymer can be present at a weight concentration based on a total dried weight of the scratch resistant layer of between 1 and 10 weight percent.Type: GrantFiled: December 1, 2000Date of Patent: November 12, 2002Assignee: Eastman Kodak CompanyInventors: Dabasis Majumdar, Charles Anderson

Patent number: 6465165Abstract: The present invention is an imaged photographic element having a protective overcoat thereon. The protective overcoat is formed by providing a photographic element having at least one silver halide light-sensitive emulsion layer. A first coating of hydrophobic polymer particles having an average size of 0.01 to 1 microns, a melting temperature of from 55 to 200° C. at a weight percent of 30 to 95, and gelatin at a weight percent of 5 to 70 is applied to form a first layer over the silver halide light-sensitive emulsion layer. A second coating of abrasion resistant particles having an average size of from 0.01 to 1 microns is applied to form a second layer over the first layer. The photographic element is developed to provide an imaged photographic element. The first and second layers are fused to form a protective overcoat.Type: GrantFiled: May 14, 1999Date of Patent: October 15, 2002Assignee: Eastman Kodak CompanyInventors: Christine J.
