Abstract:
Disclosed is a method for producing ultrafine particles of a Prussian blue-type metal complex wherein (A) an aqueous solution containing an anionic metal cyano complex having a metal atom M1 as the central metal is mixed with an aqueous solution containing metal cations of a metal atom M2 for precipitating a crystal of a Prussian blue-type metal complex having the metal atom M1 and the metal atom M2; then (B) a solution obtained by dissolving a ligand L in a solvent is mixed with the crystal of the Prussian blue-type metal complex for forming a dispersion liquid of ultrafine particles of the Prussian blue-type metal complex; and the (C) the Prussian blue-type metal complex is separated from the dispersion liquid as nanometer-sized ultrafine particles.

Abstract:
An electrode member (10A) for a reversibly color changeable display device, having: a transparent electrically-conductive structural layer (10C); and a reversibly color changeable film layer (3) disposed at one side of the transparent electrically-conductive structural layer (10C), the reversibly color changeable film layer (3) being formed by a dispersion liquid containing ultrafine particles, so that a color of the reversibly color changeable film layer (3) can be changed under control, by applying a voltage to the transparent electrically-conductive structural layer (10C) and an electrically-conductive counter electrode structural layer (10B), with an electrolyte layer (4) provided at one side of the reversibly color changeable film layer (3), and the electrically-conductive counter electrode structural layer (10B) provided at an outside of the electrolyte layer (4).
