PURPOSE: To prevent the deterioration in the recording characteristics of an optical recording medium by protecting the thin film layers of the medium with an org. protective layer. CONSTITUTION: This optical recording medium consists essentially of a substrate, thin film layers and an org. protective layer made of a layer of a cured body of a chemical beam-curable resin compsn. based on a polymerizable monomer. The protective layer contains a phosphorus compd. having one or more (meth) acryloyloxy groups in one molecule by 0.005-3 pts.wt. per 100 pts.wt. of the monomer. The protective layer is excellent in adhesiveness to the thin film layers and this optical recording medium is excellent in thin film layer protecting property. |
