    摘要: The present invention provides an overcoat for a photographic element that allows for appropriate diffusion of photographic processing solutions. The overcoat comprises 10 to 50% by weight of a enzyme-degradable biopolymer and 50 to 90% by weight of hydrophobic particles (by weight of dry laydown of the entire overcoat). An enzyme is applied to the element before, during, or after conventional photoprocessing. According to one embodiment of the invention, the photographic element can be exposed and processed using normal photofinishing equipment, with no modifications, to provide an imaged element together with a protective, water-resistant layer.
