Abstract: R-O-CH2-CO-O-(CH2)2-N=N-(CH2)2-O-CO-CH2-O-R

TRANSFER IMAGES IN COLOR ARE FORMED BY EXPOSINGG A PHOTOSENSITIVE ELEMENT CONTANING A SILVER HALIDE EMULSION AND A MONO OR DIAZO DYE WHICH CONTAINS NOT LESS THAN ONE OR MORE THAN TWO GROUPS SELECTED FROM THE GROUP REPRESENTED BY THE FORMULAE -N=N-CH2-CH2-OOC-CH2-O-R WHEREIN R IS A LOWER ALKYL GROUP SAID DYES ALSO CONTAININING NOT LESS THAN ONE OR MORE THAN TWO DIHYDROXYPHENYL SILVER HALIDE DEVELOPING RADICALS, PERMEATING THE PHOTOSENSITIVE ELEMENT WITH AN AQUEOUS ALKALNE PROCESSING COMPOSITION, AND DEACYLATION OF THE -OOC-CH2-O-R

R-O-CH2-COO-CH2-CH2-N=N-CH2-CH2-OOC-CH2-O-R GROUPS BY HYDROLYSIS TO PROVIDE HYDROXYL GROUPS THEREBY PROVIDING A NON-REVESIBLE BATHOCHROMIC SHIFT OF THE SPECIAL ABSORPTION CHARACTERISTICS OF DYE; IMMONILIZING THE DYE AS A RESULT OF THE DEVELOPMENT OF THE EXPOSED AREAS OF THE EMULSION. AND TRANSFERRING BY DIFFUSION, AT LAST A PORTION OF THE IMAGEWISE DISTRIBUTION OF DYES TO A SUPERPOSED IMAGE RECEIVING LAYER TO PROVIDE A POSITIVE DYE IMAGE THEREIN.

Abstract: THIS INVENTION RELATES TO PHOTOGRAPHIC PROCESS EMPLOYING PHOTOGRAPHICALLY INERT COMPOUNDS WHICH ARE STABLE IN THE PHOTOGRAPHIC PROCESSING COMPOSITION BUT CAPABLE OF UNDERGOING CLEAVAGE IN THE PRESENCE OF AN IMAGEWISE DISTRIBUTION OF SILVER IONS AND/OR SOLUBLE SILVER COMPLEX CONTAINING SILVER IONS MADE AVAILABLE AS A FUNCTION OF DEVELOPMENT TO LIBERATE A REAGENT IN AN IMAGEWISE DISTRIBUTION CORRESPONDING TO THAT OF SAID SILVER ION AND/OR SAID COMPLEX. IN ONE EMBODIMENT, THE PHOTOGRAPHICALLY INERT COMPOUND IS SUBSTANTIALLY NON-DIFFUSIBLE IN THE PHOTOGRAPHIC PROCESSING COMPOSITION AND THE REAGENT RELEASED THEREFROM AS A FUNCTION OF DEVELOPMENT IS DIFFUSIBLE IN THE PROCESSING COMPOSITION. IN ANOTHER EMBODIMENT, THE DIFFUSIBLE REAGENT RELEASED IS A DIFFUSIBLE DYE. COMPOUNDS APRTICULARLY USEFUL FOR LIBERATING A REAGENT ARE 1,3-SULPHUR-NITROGEN COMPOUNDS, E.G., THIAZOLIDINES, AND THEIR VINYL AND PHENYLENE ANALOGS.
