Abstract:
1. A method for producing a fine metal particle dispersion in a non-aqueous solvent, comprising the steps of: dissolving or dispersing a fatty acid metal salt compound in a non-aqueous solvent which is able to be phase-separated from water, wherein the fatty acid metal salt is formed from at least one fatty acid selected from saturated and unsaturated fatty acids having 3 to 22 carbon atoms; adding an aqueous solution of carbodihydrazide represented by the following Formula (1) or a polybasic acid polyhydrazide represented by the following Formula (2) to the solution or dispersion of the fatty acid metal compound to form aqueous droplets in the non-aqueous solvent and reduce the fatty acid metal compound in the non-aqueous solvent by the carbodihydrazide or polybasic acid polyhydrazide in the aqueous droplets: wherein R represents a n-valent polybasic acid residue; and removing an aqueous phase after reducing the fatty acid metal compound.
