<P>PROBLEM TO BE SOLVED: To provide an optical information recording medium which has a construction of a Blu-ray Disc, exhibits excellent recording characteristics in recording with short-wavelength laser beam irradiation, and has high strength. <P>SOLUTION: The optical information recording medium 10A has a reflection layer 18, a pigment-containing recording layer 14, a barrier layer 20, and a cover layer 16 in this order on a surface of the substrate having pregrooves, wherein an intermediate layer 22 exists between the barrier layer and the cover layer, which is formed by subjecting an ultraviolet curing composition containing a conjugated diene polymer having at least two (meth)acryloyl groups in a molecule to a curing treatment, and which has a glass transition temperature of -25°C or lower. <P>COPYRIGHT: (C)2010,JPO&INPIT |
