The hydrophobic organic solvent dispersions and coating compositions and coating member using the same of the surface-modified anhydrous zinc antimonate colloidal particles

摘要

There is provided a hydrophobic-organic-solvent dispersion containing colloidal particles of anhydrous zinc antimonate having high transparency which has not been attained hitherto, a coating composition containing the hydrophobic-organic-solvent dispersion and a member coated with the coating composition. A hydrophobic-organic-solvent dispersion comprising colloidal particles of anhydrous zinc antimonate having a primary particle diameter of 5 to 500 nm, which are surface-modified with an alkylamine and a surfactant having an acid group is used. The surfactant has a carboxylic acid group, a sulfonic acid group, or a phosphoric acid group.
