Abstract

L'invention concerne un procédé de régénération d'un révélateur chromogène usé pour le développement chromogène de matériaux photographiques, contenant au moins une couche d'émulsion d'halogénure d'argent, comprenant un traitement de régénération par des produits chimiques. Selon l'invention, on traite le révélateur chromogène usé par un échangeur d'anions et, avant de traiter le révélateur chromogène usé par l'échangeur d'anions, on le traite par un adsorbant qui adsorbe les composés qui gênent la régénération de l'échangeur d'anions usé.
