Abstract: TRANSFER IMAGES IN COLOR ARE FORMED BY EXPOSING A PHOTOSENSITIVE ELEMENT CONTAINING A SILVER HALIDE EMULSION AND A MONO OR DISAZO DYE WHICH CONTAINS NOT LESS THAN ONE OR MORE THAN TWO GROUPS SELECTED FROM THE GROUP REPRESENTED BY THE FORMULAE.

-N=N-(CH2)2-OOC-CH2-O-R

R-O-CH2-COO-(CH2)2-N=N-(CH2)2-OOC-CH2-O-R

WHEREIN R IS A LOWER ALKYL GROUP, SAID DYES ALSO CONTAINING NOT LESS THAN ONE NOR MORE THAN TWO DIHYDROXYPHENYL SILVER HALIDE DEVELOPING RADICALS; PERMEATING THE PHOTOSENSITIVE ELEMENT WITH AN AQUEOUS ALKALINE PROCESSING COMPOSITION, AND DEACYLATION OF THE

-OOC-CH2-O-R

GROUPS BY HYDROLYSIS TO PROVIDE HYDROXYL GROUPS, THEREBY PROVIDING A NON-REVERSIBLE BATHOCHROMIC SHIFT OF THE SPECTRAL ABSORPTION CHARACTERISTICS OF DYE; IMMOBILIZING THE DYE AS A RESULT OF THE DEVELOPMENT OF THE EXPOSED AREAS OF THE EMULSION; AND TRANSFERRING, BY DIFFUSION, AT LEAST A PORTION OF THE IMAGEWISE DISTRIBUTION OF DYES TO A SUPERPOSED IMAGE RECEIVING LAYER TO PROVIDE A POSITIVE DYE IMAGE THEREIN.
