摘要： The present invention is a method of forming a protective overcoat on a photographic element which element includes a processing-solution-permeable overcoat that becomes water-resistant in the final product without lamination or fusing. The method involves the incorporation of a small amount of a water-soluble organic solvent in the last step of the photographic process, i.e., during the washing step. This method allows the use of durable water-resistant protective overcoat materials with relatively high glass transition temperatures, that normally do not convert to impermeable films at low temperature, or without fusing.

摘要： 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; and applying an aqueous coating comprising polymer particles having an average size of 0.1 to 50 microns at a weight percent of 5 to 50 percent, a soft polymer latex binder at a weight percent of 1 to 3 percent, over the at least one silver halide light-sensitive emulsion layer. The silver halide light sensitive emulsion layer is developed to provide an imaged photographic element. The hydrophobic polymer particles is fused to form a protective overcoat.

摘要： The present invention relates to imaging elements, including photographic elements and recording media, having a protective overcoat that resists fingerprints, common stains, and spills. More particularly, the present invention provides a processing-solution-permeable protective overcoat that is water resistant in the final processed product. The overcoat, before formation of the image, comprises hydrophobic polymeric particles in a gelatin matrix. Subsequent treatment of the overcoat, after formation of the image, to remove the gelatin, causes coalescence of the hydrophobic particles, resulting in the formation of a water-resistant continuous protective overcoat.
