Abstract:
An information recording medium having as a bonding layer a cured product obtained by exposing an ultraviolet-curable adhesive composition comprising photopolymerization initiator and an ultraviolet-curable compound to ultraviolet radiation; wherein said initiator comprises 2,4,6-trimethylbenzoyldiphenylphosphine oxide; and said ultraviolet-curable compound is a resin composed of 20-100 w/w % of a monomer having at least one (meth)acryloyl group in the molecule and 5-80 w/w % of an oligomer having at least two (meth)acryloyl groups in the molecule; and said bonding layer exists between two opaque substrates which show transmittance of 0.01 to 20% at all wavelengths of energy beams in the region not less than 280 nm but no more than 380 nm, respectively.
