ABSTRACT:
When color reversal materials are developed by a process that comprises prolonged contact with the first, or black-and-white developer, images with a color mismatch or speed deficiency can occur. Such undesirable results can be reduced or eliminated by including in the reversal material, a layer of colloidal elemental silver. The layer can be adjacent to a light sensitive, silver halide-containing layer, which is present within a color record who's speed is to be increased in order to reduce the color mismatch. The amount of colloidal elemental silver employed is less than that used in the art to protect an underlying light sensitive, silver halide layer from exposure by unwanted light.
