Abstract
A method of fusing a protective layer on a photographic element by the steps of: providing a photographic element having a silver halide light-sensitive emulsion layer; applying a hydrophobic polymeric coating to the silver halide light sensitive emulsion layer; and fusing the hydrophobic polymeric coating to the silver halide light sensitive emulsion layer to form a protective overcoat, the fusing step comprising: passing the photographic element through a nip formed between a heated fuser belt and a roller wherein the fuser belt has an overcoat containing an optional siloxane intermediate layer and a silsesquioxane polymer surface layer coated on said intermediate layer.
