PHOTOPOLYMERIZED RESIN COMPOSITION FOR OPTICAL RECORDING MEDIUM, CURED MATERIAL, AND OPTICAL RECODING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide: a photopolymerized resin composition for an optical recording medium, which are excellent in curing and demolding, improves resistance to weatherability of the optical recording medium for recording and reproducing by a blue laser beam, and achieves highly reliable recording and reproducing; a cured material; and an optical recording medium having a layer formed by such a resin component.SOLUTION: The photopolymerized resin composition used for the optical recording medium which records and reproduces by the blue laser beam includes a photopolymerized resin and benzotriazole chemical compound having a predetermined configuration. The optical recording medium has a layer formed by the photopolymerized resin composition, and the layer is 1 to 200 μm in thickness.
