Abstract

La présente invention est relative à la photographie. On forme une image en couleurs dans un produit photographique portant une image argentique et contenant un composé libérateur de colorant par traitement du produit photographique par une solution de blanchiment qui comprend un complexe de cobalt III et un composé formateur de sel d'argent qui est incapable d'oxyder l'argent; puis par traitement par une solution d'amplification basique comprenant un peroxyde et un développateur à oxydation croisée. On transfère ensuite l'image de colorant mobile obtenue sur une feuille réceptrice. A la fig. 1, la courbe A représente la courbe sensitométrique de l'image argentique, la courbe B celle de l'image argentique blanchie et la courbe C celle de l'image de colorant. Application à la formation d'images en couleurs par transfert.
