Abstract: the present invention is directed to a photographic element comprised of a support and, as coatings on the support, a layer comprised of a silver haloiodide emulsion sensitized to green light and a layer comprised of a silver haloiodide emulsion sensitized to red light. Interposed between these layers is a colloidal silver layer. The presence of the colloidal silver produces a favorable interimage effect, as compared to that achieved in its absence.
