Versuchsvorschrift

A mixture of purified water (2.7 g) and isopropyl alcohol (50 g) was dropped to a mixture of zirconium tetraisopropoxide (32.7 g), isopropyl alcohol (50 g) and acetylacetone (50 g). After completion of dropping, the mixture was agitated for 2 hours, subjected to hydrolytic condensation and heated to reflux for 2 hours. PGMEA (200 g) was added thereto and was concentrated under reduced pressure to obtain a PGMEA solution of a zirconium-containing condensate (B-II) (250 g). The solid content concentration of the zirconium-containing condensate was 10.5%.
