<P>PROBLEM TO BE SOLVED: To provide an ultraviolet-curing resin composition which ensures high hardness of a coating film after curing and is excellent in adhesion and inhibition of warp after application to a plastic substrate and a cured product thereof, and to provide an ultraviolet-curing resin composition useful as a protective layer (transparent cover layer) used in an optical recording medium such as a Blu-ray disc and an optical recording medium using the same. <P>SOLUTION: The ultraviolet-curing resin composition includes at least (a) a photopolymerization initiator represented by formula (1) (wherein R<SP>1</SP>represents a hydrogen atom or a methyl group; R<SP>2</SP>represents an organic residue; and R<SP>3</SP>represents a hydrogen atom or a methyl group), (b) a polymerizable monomer having an amide group, and (c) an oligomer or polymer having a (meth)acryloyl group. <P>COPYRIGHT: (C)2009,JPO&INPIT |
