MICELLE DISPERSION AND METHOD FOR PREPARATION THEREOF

Title:

MICELLE DISPERSION AND METHOD FOR PREPARATION THEREOF

Document Type and Number:

WIPO Patent Application WO/2000/053828

Kind Code:

A1

Abstract:

A micelle dispersion having an aqueous medium and, dispersed therein, hydrophobic particles, electrically conductive particles and a ferrocene derivatives surfactant, characterized in that the equilibrium concentration of the oxidized form of the ferrocene derivative surfactant is 40 $g(m)g/ml or less and that of the reduced form thereof is 50 to 300 $g(m)g/ml; and a method for preparation of a micelle dispersion having an aqueous medium and, dispersed therein, hydrophobic particles, electrically conductive particles and a ferrocene derivative surfactant, characterized as comprising removing the oxidized form of the ferrocene derivative surfactant by means of an ion exchange resin and/or a reducing agent. The micelle dispersion can be used for producing a color filter in improved yield without causing a multicolor overlap phenomenon.
