ENHANCEMENT OF INTERIMAGE EFFECTS Abstract of the Disclosure The present invention is directed to a process of forming a photographic element capable of forming a reversal image including a support and two silver halide emulsion layers primarily responsive to a different triad of the visible spectrum upon imagewise exposure of the photographic element and positioned to permit iodide ion migration therebetween upon development. Each emulsion layer contains silver halide grains capable of forming a latent image upon imagewise exposure and a hydrophilic colloid suspending the grains. One other of the silver halide emulsion layers additionally contains suspended in the hydrophilic colloid and interspersed with the latent image forming silver halide grains surface fogged silver halide grains which are spontaneously developable inde- pendently of imagewise exposure of the photographic element. A favorable interimage effect can be obtained when the photo- graphic element is processed, following imagewise exposure, to form a reversal image. -1-
