Abstract
A hydrophobic organic solvent-dispersed sol of anhydrous zinc antimonate colloidal particles and a method for producing the same. The hydrophobic organic solvent-dispersed sol includes surface-modified anhydrous zinc antimonate colloidal particles dispersed in a hydrophobic organic solvent having a water solubility of 0.002 to 12% by mass. The surface-modified anhydrous zinc antimonate colloidal particles are formed by: coating outer surfaces of anhydrous zinc antimonate colloidal particles (A) serving as cores with at least one substance (B) of colloidal particles of a composite oxide containing silica and stannic oxide or silica and antimony pentoxide at a silica/stannic oxide or silica/antimony pentoxide ratio of 0.1 to 10, an oligomer of the colloidal particles, or a mixture of the colloidal particles and the oligomer to form modified anhydrous zinc antimonate colloidal particles (C); and bonding an organosilicon compound and an amine compound to surfaces of the colloidal particles (C).
