PROBLEM TO BE SOLVED: To provide an ultraviolet-curable resin composition which forms a coating film excellent in abrasion resistance and slipperiness, is excellent in applicability with a spin coater, and is used as a hard coating agent for optical disks. SOLUTION: This composition contains (a) an organic-inorganic composite obtained by subjecting a silica sol and an acrylate having an alkoxysilyl group to hydrolysis and condensation, (b) a polyfunctional acrylate having at least three acryloyl groups in the molecule, (c) an acrylic resin having an organosiloxane backbone, (d) propylene glycol monomethyl ether and/or propylene glycol monomethyl ether acetate, and (e) photopolymerization initiator. |
