摘要
An optical disc of the present invention includes at least a light reflection layer and a light transmission layer formed on a substrate, wherein recording and reading are performed by a laser beam through the light transmission layer, the light transmission layer is formed from a cured film of a ultraviolet-curable composition containing an epoxy acrylate resin obtained by reacting a half ester compound (A), which is obtained from a lactone-adduct of a hydroxyalkyl (meth)acrylate (a1) and a dibasic acid anhydride (a2), and an epoxy resin (B), and the film thickness of the light transmission layer is from 50 to 150 μm.
