Abstract
A fine metal particle-dispersion solution and a method for the solution are disclosed which enables to form a transparent conductive film having an uniform distribution of at least two kinds of metals and is produced by mixing an aqueous solution (A) of at lest one metal salt, the metal comprising one or more metals selected from the group consisting of Au, Pt, Ir, Pd, Ag, Rh, Ru, Os, Re and Cu and an aqueous solution (B) including citrate ion and ferrous ion under an atmosphere having substantially no oxygen to produce fine metal particles. A multi-layers conductive film having a low reflectivity, a low resistance and an excellent durability is available by using the dispersion solution of the present invention comprising Ag—Pd fine particles.
