PROBLEM TO BE SOLVED: To provide a comparatively inexpensive dispersion formed by dispersing titanium oxide particles uniformly in a nanoparticle level into a low-polarity organic solvent which is considered to be difficult to have dispersion of titanium oxide particles therein, without water inclusion that causes contamination, and without using a dispersant or a stabilizer.SOLUTION: A nonpolar organic solvent dispersion of titanium oxide is formed by dispersing, into a nonpolar organic solvent, hydrophobic titanium oxide fine powder obtained by performing a dry surface treatment with a silane coupling agent and/or a silicone compound on the surface of titanium oxide fine powder obtained by hydrolyzing a volatile titanium compound in a vapor-phase flame containing hydrogen. |
