    摘要: By using an ultraviolet-curable composition, which contains a specific ultraviolet-curable compound obtained by modifying a bisphenol epoxy compound with a polyester having a flexible structure, as a light transmission layer. Accordingly, the present invention achieves an optical disk having excellent characteristics such as excellent durability, excellent light resistance and excellently reduced warp, while suppressing deterioration of the light reflection film due to environment of high temperature and high humidity or light exposure. Consequently the ultraviolet-curable composition of the present invention is most suitable for optical disks having a thick light-transmitting layer on which recording/reproduction is performed by using a blue laser.
