Color diffusion transfer film units comprising a layer which contains a synthetic polymer-benzenoid silver halide developing agent complex and process for their use

Abstract

Abstract THE PRESENT INVENTION RELATES TO PHOTOGRAPHY AND, MORE PARTICULARLY, TO DIFFUSION TRANSFER PROCESS PHOTOGRAPHIC FILM UNITS WHICH COMPRISE A PHOTOSENSITIVE ELEMENT ADAPTED TO PROVIDE, BY DIFFUSION TRANSFER PHOTOGRAPHIC PROCESSING, SELECTIVE DYE IMAGE RECORDATION OF INCIDENT ACTINIC RADIATION AS A FUNCTON OF THE POINT-TO-POINT DEGREE OF PHOTOSENSTIVE ELEMENT EXPOSURE, WHICH FILM UNIT INCLUDES A PLURALITY OF ESSENTIAL LAYERS INCLUDING A PHOTOSENSITIVE SILVER HALIDE LAYER HAVING ASSOCIATED THEREWITH DYE DEVELOPER, I.E., A DYE WHICH IS A SILVER HALIDE DEVELOPING AGENT, WHICH IS DIFFUSIBLE DURING PROCESSING AS A FUNCTION OF THE POINT-TO- POINT DEGREE OF SILVER HALIDE LAYER EXPOSURE TO INCIDENT ACTINIC RADIATION AND A LAYER ADAPTED TO RECEIVE IMAGE-FORMING MATERIAL DIFFUSING THERETO, AT LEAST ONE OF THE LAYERS OF THE FILM UNIT COMPRISING A PARTICULATE DISPERSION OF A SYNTHETIC POLYMER-SILVER HALIDE DEVELOPING AGENT COMPLEX DISSOCIABLE AS A FUNCTION OF PH TO PROVIDE A PROCESSING COMPOSITION SOLUBLE SILVER HALIDE DEVELOPING AGENT; AND TO SPECIFIED DIFFUSION TRANSFER PROCESSES EMPLOYING SUCH FILM UNITS.
