Abstract

Procédé pour former une image d'argent très contrastée. On traite un élément, photographique à halogénure d'argent photosensible comportant un support, une couche d'émulsion d'halogénure d'argent revêtant le support et une autre couche colloïdale hydrophile, au moins une de ces couches renfermant un composé pratiquement non diffusible ayant un pouvoir d'oxydation vis-à-vis d'un agent développateur de type hydroquinone, avec un révélateur ne renfermant pas d'agent développateur de type hydroquinone après exposition selon une image. Application à la formation d'images d'argent très contrastées avec des matières photographiques photosensibles de type lithographique
