ABSTRACT:
In an optical data storage medium comprising a resin, substrate, a primary coat formed thereon and a recording layer of a dye decomposable by a laser beam formed on the primary coat, said primary coat is a silicone resin layer whose surface had been subjected to a plasma treatment. The primary coat prevents the substrate from attack by solvent for forming the recording layer, and enables the recording layer to be uniform in thickness with good adhesion.
