Versuchsvorschrift

A mixture of purified water (2.7 g) and isopropyl alcohol (50 g) was dropped to a mixture of titanium tetraisopropoxide (14.2 g), zirconium tetraisopropoxide (16.3 g) and isopropyl alcohol (50 g). After completion of dropping, acetylacetone (20 g) was added to the mixture, agitated for 2 hours, subjected to hydrolytic condensation and heated to reflux for 2 hours. PGMEA (150 g) was added thereto and was concentrated under reduced pressure to obtain a PGMEA solution of a titanium-zirconium-containing condensate (B-V) (200 g). The solid content concentration of the titanium-zirconium-containing condensate was 10.9%.
