Abstract
Provided are an organic solvent dispersion of titanium oxide containing at least titanium oxide fine particles each having an average primary particle diameter of 3 nm or more to 50 nm or less; a titanate-based surface treatment agent formed of a compound represented by the following general formula (1):(R1O)m—Ti—Xn (1)where R1 represents a methyl, ethyl, or isopropyl group; X represents —O—SO2—R2 or —O—P(OH)O—O—PHO—O—R2; R2 represents an alkyl or aryl group having 1 to 16 carbon atoms; m represents a numerical value of 1 or more to 3 or less, and n represents a numerical value of 1 or more to 3 or less, provided that m+n=4; a polyether-based dispersant; and an alcohol-based solvent, and an optical material containing the organic solvent dispersion of titanium oxide and a resin.
