CONDUCTIVE INORGANIC OXIDE DISPERSION COMPOSITION

WIPO Patent Application WO/2007/114151

A1

Disclosed is a conductive inorganic oxide dispersion composition exhibiting good dispersibility of a conductive inorganic oxide powder in a polar solvent. This conductive inorganic oxide dispersion composition enables to form a conductive coating film having high transparency and small decrease in conductivity. Specifically disclosed is a conductive inorganic oxide dispersion composition which is obtained by dispersing a conductive inorganic oxide powder in a dispersion medium while using a terminally carboxylated polylactone compound as a dispersing agent. The terminally carboxylated polylactone compound is obtained by ring-opening polymerizing a lactone compound while using, as an initiator, at least one substance selected from hydroxycarboxylic acids and condensation products of hydroxycarboxylic acids. The weight average molecular weight of the terminally carboxylated polylactone compound is 500-5000.
