Abstract:
A photographic element comprising:(a) a support; (b) at least one silver-halide emulsion layer superposed on a side of said support; and (c) overlying the silver emulsion layer, a processing-solution-permeable protective overcoat having a laydown of at least 0.54 g/m2 (50 mg/ft2) made from a coating composition comprising the following: (i) 30 to 95%, by weight of solids, of water-dispersible polymer in the form of particles having an average particle size of less than 500 nm and a Tg between âˆ’40Â° C. and 80Â° C., and (ii) 5 to 70%, by weight of solids, of water-soluble polymer such that more than 30 weight percent of water-soluble polymer is washed out during photographic processing; wherein the composition is essentially free of polyurethane and polyester polymer, wherein the weight ratio of the water-dispersible polymer to the water-soluble polymer is between 50:50 to 90:10, wherein the applied overcoat comprises less than 5% by weight of gelatin, and whereby the overcoat forms a water-resistant overcoat after photoprocessing.
