Patent number: 6194130Abstract: The present invention is a photographic element which includes a support, at least one silver halide emulsion layer superposed on the support and a processing-solution-permeable protective overcoat overlying the silver halide emulsion layer. The processing solution permeable overcoat is composed of a urethane-containing component having acid functionalities wherein a weight ratio of a polyurethane-containing component in the copolymer comprises from 20 to 100 percent and a weight ratio of an optional vinyl component in the copolymer comprises from 0 to 80 percent, which urethane-containing component of the overcoat may comprise either a single polyurethane polymer or an interpenetrating network comprising two or more polymers. The overcoat further comprises a polyvinyl alcohol polymer having a molecular weight of about 150,000 or less, with the proviso that the degree of hydrolysis is less than 95% when the molecular weight is more than about 100,000.Type: GrantFiled: November 23, 1999Date of Patent: February 27, 2001Assignee: Eastman Kodak CompanyInventors: Mridula Nair, Tamara K. Jones, Tiecheng A. Qiao

Patent number: 6187517Abstract: The present invention provides a gelatin-based aqueous-coatable overcoat for a photographic element that allows for appropriate diffusion of photographic processing solutions. The overcoat comprises 10 to 50% by weight gelatin and 50 to 90% by weight of hydrophobic particles (by weight of dry laydown of the entire overcoat) having an average diameter of 10 to 500 nm. A proteolytic enzyme is applied to the clement in reactive association with the overcoat layer. A photographic element according to one embodiment of the invention can be exposed and processed using normal photofinishing equipment, with no modifications, to provide an imaged element together with a protective, water-resistant layer.Type: GrantFiled: June 9, 2000Date of Patent: February 13, 2001Assignee: Eastman Kodak CompanyInventors: Thomas H. Whitesides, Hwei-Ling Yau, Amy Jasek
