Method for preparing non-photosensitive fatty acid silver salt grains and an apparatus for preparing the same

Abstract

A method for preparing non-photosensitive fatty acid silver salt grains was disclosed. The method has the step of reacting a silver ion-containing solution, the solvent of which being water or a mixture of water and an organic solvent, with a solution of a fatty acid alkali metal salt, the solvent of which being water, an organic solvent, or a mixture of water and an organic solvent, to obtain fatty acid silver salt grains; in which the reaction is proceeded by mixing the silver ion-containing solution and the solution of the fatty acid alkali metal salt within a closed mixing means. The dispersion of the non-photosensitive fatty acid silver salt grains prepared according to such method is excellent in dispersion stability and coating property.
