Abstract
Procédé de fabrication d'émulsions photographiques d'halogénures d'argent contenant des cristaux d'halogénure d'argent du type maclé. Le perfectionnement apporté au procédé du brevet principal est caractérisé par le fait que dans la phase a dudit procédé, on procède à la sensibilisation chimique des cristaux d'halogénure d'argent ayant la structure de réseau hexagonal et contenant au moins 90 % en mole d'iodure. Ce nouveau procédé augmente la sensibilité interne des émulsions d'halogénure d'argent terminées.
