Abstract

LA PRESENTE INVENTION CONCERNE UN PROCEDE DE PHOTOGRAPHIE EN COULEURS PAR INVERSION. SELON CE PROCEDE, ON EXPOSE UN PRODUIT PHOTOGRAPHIQUE COMPRENANT UNE COUCHE D'EMULSION AUX HALOGENURES D'ARGENT NEGATIVE ASSOCIEE A UN COMPOSE INDIFFUSIBLE, LIBERATEUR DE COLORANT DIFFUSIBLE PAR OXYDATION CROISEE EN FONCTION DU DEVELOPPEMENT DES HALOGENURES D'ARGENT. APRES DEVELOPPEMENT ET ELIMINATION DU COLORANT DIFFUSIBLE, IL RESTE UNE IMAGE D'HALOGENURES D'ARGENT RESIDUELLE POSITIVE QU'ON VOILE ET QU'ON DEVELOPPE, FORMANT AINSI UNE IMAGE POSITIVE DE COLORANT DIFFUSIBLE QU'ON TRANSFERE SUR UNE COUCHE RECEPTRICE. CE PROCEDE PERMET D'OBTENIR, PAR DIFFUSION ET TRANSFERT, UNE IMAGE EN COULEURS POSITIVE A PARTIR D'UNE EMULSION NEGATIVE ET DE LIBERATEUR DE COLORANT DIFFUSIBLE.THE PRESENT INVENTION RELATES TO A COLOR PHOTOGRAPHY PROCESS BY INVERSION. ACCORDING TO THIS PROCESS, A PHOTOGRAPHIC PRODUCT IS EXPOSED INCLUDING A NEGATIVE SILVER HALOGEN EMULSION LAYER ASSOCIATED WITH AN INDIFFUSABLE COMPOUND, DIFFUSABLE DYE RELEASE BY CROSS OXIDATION AS A FUNCTION OF THE DEVELOPMENT OF THE SILVER HALOGENIDES. AFTER DEVELOPMENT AND REMOVAL OF THE DIFFUSABLE COLORANT, A POSITIVE RESIDUAL SILVER HALOGEN IMAGE REMAINS THAT WE SAIL AND DEVELOP, THUS FORMING A POSITIVE IMAGE OF DIFFUSABLE DYE THAT IS TRANSFERRED TO A RECEIVING LAYER. THIS PROCESS ALLOWS TO OBTAIN, BY DIFFUSION AND TRANSFER, A POSITIVE COLOR IMAGE FROM A NEGATIVE EMULSION AND DIFFUSABLE COLOR RELEASER.
