<P>PROBLEM TO BE SOLVED: To provide a curable resin composition for an optical disk which can give a cured material in which permanent deformation of pressure welding marks, dents, or the like is sufficiently suppressed and achieve more reliable recording and reproducing, wherein warpage is remarkably small, and to provide a cured material obtained by curing the same, and an optical disk having a layer formed by curing such a resin composition. <P>SOLUTION: The curable resin composition for the optical disk includes (a) a (meta) acrylate compound having an alicyclic structure and/or an aliphatic heterocyclic structure, (b) at least one species of a compound selected from a group consisting of a urethane (meta) acrylate compound, a polyester (meta) acrylate compound, an epoxy (meta) acrylate compound, and oligomer and/or polymer having a (meta) acryloyl group at a side chain, (c) another (meta) acrylate compound, and further (d) a photopolymerization initiator. <P>COPYRIGHT: (C)2011,JPO&INPIT |
