1-butanol (BOH) solution (500 g) of deionized water (27 g) was agitated with BOH solution (500 g) of a titanium tetrabutoxide (340 g) and dropped at room temperature for 2 hours. 3-methyl-1,3-hexanediol (132 g) was added to a solution obtained and agitated at room temperature for 30 minutes. After the solution was concentrated under reduced pressure at 40° C., it was heated to 60° C. and heating was continued under reduced pressure to generate no distillate. Then, PGMEA (1,200 g) was added thereto and heated under reduced pressure at 50° C. until no BOH was distilled to obtain a PGMEA solution of a titanium-containing compound [B-III] (1,000 g) (compound concentration: 22%). The molecular weight (Mw) of the compound measured in terms of polystyrene was 1,250.
