Abstract

L'invention se rapporte à la photographie. Elle concerne un procédé pour la sensibilisation d'une émulsion photosensible de gélatine-halogénure d'argent avant son application sur un support, selon lequel l'émulsion de gélatine-halogénure d'argent est préparée dans un récipient d'alimentation et introduite ensuite dans un appareil d'enduction pour application sur un support pelliculaire, caractérisé en ce qu'on ajoute à l'émulsion, dans le récipient d'alimentation, 1) du bisulfite de glutaraldéhyde, du bisulfite de succinaldéhyde ou un bisulfite de glutaraldéhyde substitué, et 2) un acide sulfinique aromatique ou un sel soluble dans l'eau d'un tel acide. Utilisation pour la préparation d'émulsions.
