RADIATION CURING COMPOSITION, METHOD FOR PRODUCING RADIATION CURING COMPOSITION, CURED PRODUCT AND OPTICAL MATERIAL |
摘要 |
<P>PROBLEM TO BE SOLVED: To provide a radiation curing resin composition which is less affected by an influence of remaining solvents and shows an optically excellent transparency and to provide a method for producing the same and a radiation cured resin product having a good dimensional stability and adhesiveness. <P>SOLUTION: The radiation curing composition comprises a silica grain, which is obtained by direct mixing of an alkoxyl silane oligomer and a silane coupling agent and by adding to the mixture a water soluble catalyst and the reaction mixture is subjected to hydrolysis reaction for 0.5-24 hours at 10-100°C, and a polymerizable monomer comprised of a (meth)acrylate compound of at least 2 valent. A cured product is obtained using the composition by UV radiation and an optical material is made of the cured product. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
