摘要
PROBLEM TO BE SOLVED: To provide an active energy ray curable composition for an interlayer of a multilayer structure optical information medium to form an interlayer with less reduction in adhesion to a recording layer against changes in temperature and humidity; and a multilayer structure optical information medium having an interlayer with less reduction in adhesion.;SOLUTION: A multilayer structure optical information medium has at least two information recording layers and an interlayer having a thickness of 3 to 30 μm between the two adjacent information recording layer. The composition is an active energy ray curable composition for an interlayer of the multilayer structure optical information medium to form the interlayer. The composition contains a polymerizable compound and a photoinitiator with a mass decrease rate of 4% or less when kept at 110°C for one hour, and the interlayer is a cured product of the composition.;COPYRIGHT: (C)2013,JPO&INPIT
