Abstract

An object of the present invention is to provide an ultraviolet curable resin composition capable of imparting excellent recording signal characteristics and durability to an optical disc having an organic dye recording layer. The ultraviolet curable resin composition of the present invention is an ultraviolet curable resin composition applied to an optical disc having an organic pigment recording layer, and is characterized in that it contains (A) having the following general formula (1) (in the formula, n represents (integer of 2 to 16) represented by the structure of (meth)acrylate and (B) photopolymerization initiator.

Description

technical field [0001] The present invention relates to an ultraviolet curable resin composition useful for an optical disk having an organic dye recording layer. Background technique [0002] At present, there are CD-R and CD-RW in which a recording layer, a reflective layer, and a protective layer including an ultraviolet curable resin are laminated on a polycarbonate substrate with a thickness of 1.2 mm as optical disc recording media that have been put into practical use; UV-curable resin DVD-R, DVD+R, DVD-RW, DVD+RW composed of a 0.6mm-thick polycarbonate substrate and a 0.6mm-thick polycarbonate substrate with a recording layer and a reflective layer , DVD-RAM. [0003] In addition, in recent years, a Blu-ray Disc (BD-R) having a recording capacity approximately five times that of a single-layer DVD has been sold. Blu-ray Disc refers to a structure in which a reflective layer, a recording layer, and an interface layer are formed on a transparent or opaque plastic sub...
