Abstract
A clear protective overcoat is provided to an image formed in a silver halide photographic element. The overcoat is formed by electrostatically applying a uniform distribution of clear toner to an imaged photographic element and then fusing the toner to form an overcoat. The toner can be applied only in a limited area of the element.
