Abstract

LA PRESENTE INVENTION EST RELATIVE A LA PHOTOGRAPHIE EN COULEURS. LE PROCEDE SUIVANT L'INVENTION UTILISE 1 UN PRODUIT PHOTOGRAPHIQUE COMPRENANT AU MOINS UNE COUCHE D'EMULSION AUX HALOGENURES D'ARGENT A LAQUELLE EST ASSOCIE UN COMPOSE FORMATEUR DE COLORANT PAR OXYDO-REDUCTION, 2 UNE PREMIERE SOLUTION D'AMPLIFICATION REDOX QUI CONTIENT UN COMPLEXE DE COBALT III ET UN DEVELOPPATEUR DES HALOGENURES D'ARGENT ET 3 UNE DEUXIEME SOLUTION D'AMPLIFICATION REDOX QUI COMPREND UN PEROXYDE ET UN AGENT REDUCTEUR FORMATEUR D'IMAGE DE COLORANT TEL QU'UN DEVELOPPATEUR CHROMOGENE. APPLICATION A L'OBTENTION D'IMAGE DE COLORANT A DENSITE MAXIMALE AMELIOREE. A LA FIGURE 1, LES COURBES A, B ET C CORRESPONDENT A DES PRODUITS PHOTOGRAPHIQUES TRAITES PAR DES PROCEDES DE LA TECHNIQUE ANTERIEURE AVEC DES SOLUTIONS DE TRAITEMENT CONTENANT RESPECTIVEMENT NI COMPLEXE DE COBALT (III) NI PEROXYDE (COURBE A), SEULEMENT UN PEROXYDE (COURBE B), SEULEMENT UN COMPLEXE DE COBALT (III) (COURBE C). LE PROCEDE SUIVANT L'INVENTION PERMET D'OBTENIR UNE IMAGE DE COLORANT CORRESPONDANT A LA COURBE D DONT LA DENSITE MAXIMALE EST NETTEMENT AMELIOREE.
