| 摘要 |
An organometallic polymer material is obtained which excels in translucency, shows improved hardness after it is cured and exhibits high reliability at high temperature and high humidity. Characteristically, the organometallic polymer material contains an organometallic polymer having an -M-O-M- bond (M indicates a metal atom), a metal alkoxide having a single hydrolyzable group and/or its hydrolysate and an organic polymer having a urethane bond and a methacryloxy or acryloxy group, and preferably further contains an organic anhydride and/or an organic acid.
