Abstract
Image formation in photosensitive materials can be simplified by photoprocessing the imagewise exposed materials using photochemical delivery articles that consist essential of nonporous substrate and a hydrogel that contains the one or more photochemicals needed for image formation. The delivery articles can be laminated or other wise contacted with the imaged photographic materials on the silver halide emulsion side allowing photochemicals to diffuse into and out of the materials for the desired chemical reactions. Multiple delivery articles can be used in sequence to provide the desired sequence of photochemical reactions.
