ABSTRACT:
A method of forming a protective overcoat on a photographic element including the steps of providing a photographic element having a silver halide light-sensitive emulsion layer; applying a hydrophobic polymeric coating over the silver halide light sensitive emulsion layer; fusing the hydrophobic polymeric coating to the photographic element over the silver halide light sensitive emulsion layer to form a protective overcoat; by passing the photographic element through a nip formed between a heated fuser belt having a resin made by curing a composition including siloxanes and a roller to fuse the hydrophobic polymeric coating to the photographic element, wherein the siloxanes having a ratio of difunctional to trifunctional units of 1:1 to 1:2.7 and at least 90% of total number of functional units in the siloxanes are difunctional and trifunctional units, a weight average molecular weight of 5,000 to 50,000 grams/mole, and an alkyl to aryl ratio of 1:0.1 to 1:1.2.
