Patent ID: 8409687

Claim:
An optical disc, comprising: a substrate; a light-reflecting layer, disposed above the substrate; an information recording layer, disposed above the light-reflecting layer; a light-transmitting layer, disposed above the information recording layer; and a hard coat layer as an outermost layer, disposed above the light transmitting layer, wherein information is read from or recorded onto the optical disc with a blue laser beam incident from the hard coat layer side, and the hard coat layer is formed of a cured product of a UV-curable composition, wherein the UV-curable composition comprises a fluorine-containing UV-curable resin containing a poly(perfluoroalkylene ether) chain and a UV-curable group, and wherein the fluorine-containing UV-curable resin is a fluorine-containing UV-curable resin obtained by allowing a polymer (P 1 ), which is obtained by copolymerizing a compound (d1) having a structural segment including a poly(perfluoroalkylene ether) chain having radically polymerizable unsaturated groups at both ends and a radically polymerizable unsaturated monomer (d2) having a reactive functional group (R 1 ) as essential monomer components, to react with a compound (d3) having a functional group (R 2 ) reactive to the functional group (R 1 ) and a UV-curable group.
