Optical recording medium.

摘要

An optical recording medium, particularly a magneto-optical recording medium, resistant to oxidation deterioration even in a hot and humid atmosphere, is provided by forming an organic protecting adhesive layer (4) of a UV-cured resin having an acid value of not more than 1.5; and a softening point of not less than 50 DEG C. The UV-cured resin layer comprises 15 to 85% by weight of acrylate and/or methacrylate having at least three functionalities; 15 to 70% by weight of a compound having a linear structure and having a molecular weight of at least 300, the compound preferably having at least one ethylenically unsaturated bond and a molecular weight of at least 150 per ethylenically unsaturated bond; and a photopolymerization initiator.
