Abstract

L'invention est relative à des coupleurs utiles en photographie. Ces coupleurs comprennent deux groupements coupleurs à groupe méthylène réactif, reliés entre eux par un groupe de liaison fixé sur leur groupe méthylène respectif. Ce groupe de liaison peut être un groupe di(oxyphényl)carbonyle, di(oxyphényl)sulfonyle ou di(oxyphényl)alkylènedisulfonamido. Application à l'obtention d'images de colorants jaunes présentant une bonne densité, bien qu'on utilise une faible quantité de ces coupleurs dont la masse moléculaire, par groupement coupleur, est plus faible que celle des coupleurs de la technique antérieure.
