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.
