<p><P>PROBLEM TO BE SOLVED: To provide metal particulates which are fine and further have satisfactory dispersibility. <P>SOLUTION: Using, as a reducing agent, a compound obtained by subjecting a phenol compound such as pyrogallol, phloroglucinol and gallic acid to oxidative polymerization with an oxidizer or the like, the reducing agent is mixed with a metal compound, and the metal compound is reduced, so that metal particulates is obtained in such a state that the oxidatively-polymerized product and the oxidized body thereof are present on the surfaces of the produced metal particulates, and by the dispersion effect thereof, the particles in a flocculated state are less dispersed. The metal colloidal liquid obtained by dispersing the metal particulates into a solvent is suitably used for ornaments or the like. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
