  • Method of activating a protective layer on a photographic element employing an organic solvent in the wash solution
    Patent number: 6524777
    Abstract: 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.

  • Hydrolyzed water-resistant protective overcoat for an imaging element
    Patent number: 6258520
    Abstract: 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.

  • Pre-coated, fused plastic particles as a protective overcoat for color photographic prints
    Patent number: 5853926
    Abstract: 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.
