Abstract
La présente invention concerne la formation d'images en couleurs, à partir d'halogénures d'argent et de coupleurs colorés. La formule générale des coupleurs colorés utilisés est la suivante : - COL - COUP - L - LEST COL représente le radical d'un colorant; COUP représente le radical d'un coupleur par exemple de type naphtol, pyrazolone, ou cétométhylénique; L représente un radical de liaison fixé sur la position de couplage du radical COUP; LEST représente un radical de lestage, qui rend le coupleur indiffusible. Lorsqu'un produit contenant une émulsion d'halogénures d'argent négative associée à un tel coupleur est développée après exposition en présence d'un développateur de type amine pnmaire, une image de colorant négative et diffusible est libérée alors que reste dans le produit développé une image de colorant positive.
