Abstract
Ω/□, with excellent antistatic properties, anti-reflection properties, and electromagnetic shielding properties, and suitable for use in forming a transparent conductive coating film excellent in reliability and durability, and a process for producing the fine metal particles. The fine metal particles include iron and noniron metal having an average particle diameter in the range of from 1 to 200 nm and an iron content in the range of from 0.1 to 3.0% by weight. The noniron metal preferably is one or more metals selected from the group consisting of Au, Ag, Pd, Pt, Rh, Ru, Cu, Ni, Co, Sn, Ti, In, Al, Ta, and Sb. Part of the surface of the fine metal particles may be in the form of an oxide and/or a hydroxide.
