Procedure

A mixture of purified water (2.7 g) and isopropyl alcohol (50 g) was dropped to a mixture of titanium tetraisopropoxide (28.4 g), isopropyl alcohol (50 g) and 2-(butylamino)ethanol (11.8 g). After completion of dropping, the mixture was agitated for 2 hours, subjected to hydrolytic condensation and heated to reflux for 2 hours. PGMEA (100 g) was added thereto and was concentrated under reduced pressure to obtain a PGMEA solution of a titanium-containing condensate (B-I) (130 g). The solid content concentration of the titanium-containing condensate was 13.5%.
