OPTICAL DISC, ULTRAVIOLET-RAY CURING-TYPE RESIN COMPOSITE THEREFOR, HARDENED MATERIAL AND ARTICLE

摘要

The present invention relates to an optical disc having as a light-transmissive layer an ultraviolet-ray curing-type resin composite containing (A) poly(tetramethylene glycol) di (meth) acrylate as a (meth) acrylate, or poly(C2 or C2 alkylene glycol - tetramethylene glycol) di (meth) acrylate that has a structure represented by forumula (1) (n indicating an integer of 1-30), (B) a photoinitiator, and (meth) acrylate (C) other than (A); and an ultraviolet-ray curing-type resin composite for an optical disc including (A), and a (meth) acrylate (C) other than (B) and (A), that are useful in an optical disc wherein the resin composite particularly has an organic dye recording layer. The optical disc showed desirable jitter values after endurance tests. Formula (1)
