Patent ID: 8614013

Claim:
An organic solvent dispersion comprising: titanium oxide fine particles each having an average primary particle diameter of 3 nm or more to 50 nm or less, wherein content of the titanium oxide fine articles contained in the organic solvent dispersion is 0.1% by weight or more to 30.0% by weight or less; a titanate-based surface treatment agent formed of a compound represented by the following general formula (1): (R 1 O) m —Ti—X n (1) where R 1 represents a methyl, ethyl, or isopropyl group; X represents —O—SO 2 —R 2 or —O—P(OH)O—O—PHO—O—R 2 ; R 2 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, wherein content of the titanate-based surface treatment agent is 10.0% by weight or more to 75.0% by weight or less with respect to weight of the titanium oxide fine particles; a polyether-based dispersant, wherein content of the polyether-based dispersant is 3.0% by weight or more to 60.0% by weight or less with respect to weight of the titanium oxide fine particles; and an alcohol-based solvent, wherein content of the alcohol-based solvent is 180% by weight or more to 100,000% by weight or less with respect to weight of the titanium oxide fine particles.
