Abstract

Procédé de fabrication d'émulsions photographiques d'halogénure d'argent contenant des cristaux d'halogénure d'argent du type maclé. Ce procédé est caractérisé par les phases suivantes : I formation de cristaux d'halogénure d'argent principalement à structure hexagonale, renfermant au moins 90 % en mole d'iodure, au sein d'un milieu dispersant colloïdal ; II addition à I de solutions aqueuses de sel d'argent et de chlorure ou de bromure de NH4 ou d'un métal alcalin comme dans le brevet principal. mais cette addition est faite à une vitesse contrôlée pour que les cristaux d'halogénure d'argent soient principalement maclés; III éventuellement augmentation de la taille des cristaux par une nouvelle addition à II de solutions aqueuses de sel d'argent et d'halogénure de métal alcalin ou d'ammonium puis IV éventuellement élimination des sels hydrosolubles fqrmés et sensibilisation chimique de l'émulsion. Application à de nombreux types de matériaux photographiques pour négatifs ou positifs directs.A process for making photographic silver halide emulsions containing twinned-type silver halide crystals. This process is characterized by the following phases: I formation of silver halide crystals, mainly of hexagonal structure, containing at least 90 mol% of iodide, in a colloidal dispersing medium; II addition to I of aqueous solutions of silver salt and chloride or bromide of NH4 or an alkali metal as in the main patent. but this addition is made at a controlled rate so that the silver halide crystals are predominantly twin; III optionally increasing the size of the crystals by a further addition to II of aqueous solutions of silver salt and of alkali metal or ammonium halide, then IV optionally removal of the hydrosoluble salts formed and chemical sensitization of the emulsion. Application to many types of photographic materials for direct negatives or positives.
