ADHESIVE COMPOSITION FOR OPTICAL DISK, CURED PRODUCT AND ARTICLE

摘要

Disclosed is an adhesive which enables to obtain a bonded optical disk, wherein optical disks having a total reflection film or a semi-transparent reflection film made of silver or a silver alloy are bonded together, which exhibits high adhesion strength between the reflection film and a cured product of the adhesive as well as between a polycarbonate substrate and the cured product of the adhesive, while having high durability equivalent to those of the conventional optical disks using semi-transparent reflective film made of gold. Specifically disclosed is an ultraviolet-curable adhesive resin composition containing a bisphenol-type epoxy (meth)acrylate (A), a di(meth)acrylate (B) and a photopolymerization initiator (C) which is characterized in that the di(meth)acrylate (B) is composed of one or more selected from a di(meth)acrylate (B-1) having an adipate structure, a di(meth)acrylate (B-2) having a caprolactone-modified structure, an alkylene oxide-modified neopentylglycol di(meth)acrylate compound (B-3) and an alkylene oxide-modified 1,6-hexanediol di(meth)acrylate compound (B-4).
