Abstract

La présente invention a trait à un matériau photosensible aux couleurs à base d'halogénure d'argent présentant une photosensibilité élevée, à faible voile, ayant une excellente granularité, et une bonne stabilité de reproduction de gradation de la couleur de la peau. Le matériau photosensible aux couleurs à base d'halogénure d'argent est caractérisé en ce que le matériau comprend un support, des couches non photosensibles et des unités de couches photosensibles au rouge, au vert et au bleu, chaque unités de couches photosensibles étant composée de deux couches photosensibles, les couches non photosensibles interposées entre la couche de photosensibilité maximale photosensible au rouge et la couche de photosensibilité minimale photosensible au vert, et toutes les couches étant formées sur le support ; la quantité d'argent appliquée à la couche de photosensibilité maximale photosensible au rouge est de 0,1 à 1, 0 g/cm2 ; la couche de photosensibilité maximale photosensible au rouge contient un composé DIR non apte à la diffusion; la couche de photosensibilité minimale photosensible au vert contient un composé DIR apte à la diffusion ; au moins une des couches non photosensibles contient un inhibiteur d'oxydation présentant une structure spécifique.
