    摘要： The present invention relates to photographic elements having a protective overcoat that resists fingerprints, common stains, and spills. The overcoat comprises an epoxy material, an acid polymer, and a water-soluble hydrophilic binder. In one embodiment, a photographic element includes a support, at least one silver halide emulsion layer superposed on the support and a processing-solution-permeable overcoat overlying the silver halide emulsion layer that becomes water-resistant in the final product without requiring lamination or fusing. The present invention is also directed to a method of making a print involving developing the photographic element.

    摘要： Color photographic materials comprise a substrate bearing a silver halide emulsion and a coupler composition comprising (a) a 2-phenylcarbamoyl-1-naphthol compound selected from the group consisting of development inhibitor releasing couplers and timed development inhibiting releasing couplers, and (b) a phenolic coupler solvent. The phenolic coupler solvent is employed to reduce dye density changes and/or dye hue changes resulting from cold storage of the photographic materials.
