    摘要： 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.

    摘要： A method for improving durability of aqueous ink deposited on a substrate having multivalent metal salt present at the surface of the substrate is disclosed. The method includes depositing aqueous ink on the surface of the substrate, wherein the aqueous ink is an anionically stabilized pigment ink, drying the substrate to substantially remove the water from the deposited aqueous ink, applying substantially pure water and heat to the dried substrate with deposited aqueous ink, and removing the applied water and heat to return the dried substrate to an ambient temperature and moisture content. The applied substantially pure water and heat are sufficient to cause a significant improvement of the durability of the deposited ink on the substrate.
