ORGANIC SOLVENT DISPERSION, RESIN COMPOSITION, AND OPTICAL DEVICE

摘要

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-T i-Xn (1) where R1 represents a methyl, ethyl, or isopropyl group; X represents -0-S02-R2 or -0-P (OH) 0-0-PHO-0-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.
