Diffusion transfer color products and processes simultaneously utilizing exposed and unexposed silver halides

Abstract

Abstract PHOTOGRAPHIC SYSTEMS FOR PREPARING COLOR TRANSFER IMAGES EMPLOYING A PHOTOSENSITIVE ELEMENT HAVING AT LEAST ONE LIGHT-SENSITIVE SILVER HOLDS EMULSION HAVING ASSOCIATED THEREAFTER A FIRST COLOR-PROVIDING MATERIAL WHICH A NORMALLY DIFFUSIBLE IN AN AQUEOUS ALKALINE PROCESSING MEDIUM AND A SECOND COLOR-PROVIDING MATERIAL WHICH IS NOT, WHEREIN THE PHOTOSENSITIVE ELEMENT IN EXPOSED AND THEREAFTER DEVELOPED, AS A FUNCTION OF DEVELOPMENT THE FIRST-NAMED MATERIAL IS SELECTIVELY IMMOBILIZED TO PROVIDE A FIRST IMAGEWISE DISTRIBUTION OF MOBILE AND DIFFUSIBLE COLOR-PROVIDING MATERIAL AND SAID SECOND-NAMED MATERIAL IS SELECTIVELY RENDERED DIFFUSIBLE TO PROVIDE A SECOND IMAGEWISE DISTRIBUTION OF MOBILE AND DIFFUSIBLE COLORPROVIDING MATERIAL IN AREAS CORRESPONDING TO SAID FIRST IMAGEWISE DISTRIBUTION, AND SAID TWO IMAGEWISE DISTRIBUTIONS OF MOBILE AND DIFFUSIBLE COLOR-PROVIDING MATERIAL ARE THEN TRANSFERRED TO A DYEABLE STRATUM TO IMPART THERETO A COLOR TRANSFER IMAGE. THE PHOTOGRAPHIC SYSTEMS ARE ALSO CHARACTERIZED AS EMPLOYING EXPOSED SILVER HALIDE TO CONTROL TRANSFER OF ONE COLOR-PROVIDING MATERIAL; AND UNEXPOSED SILVER HALIDE TO CONTROL TRANSFER OF THE OTHER.
