<P>PROBLEM TO BE SOLVED: To provide a curable resin composition for an optical recording medium that is effective for forming light-transmitting layers by coating and curing a liquid curing resin composition having a small volume shrinkage between before and after the curing in the optical recording medium for recording digital information using laser beam. <P>SOLUTION: The curable resin composition for an optical recording medium contains, as essential components, (A) a cationic curable polyorganosiloxane and (B) a cationic polymerization initiator. The curable resin composition has an extremely low volume decrease rate between before and after the curing (measured by the gravity method) thereby the influence of the substrate bow can be decreased. <P>COPYRIGHT: (C)2009,JPO&INPIT |
