2. Description of the Related Art Optical discs such as compact discs and magneto-optical recording discs have a structure having a metal thin film layer formed by vapor deposition or sputtering on a transparent substrate such as polycarbonate. Since this metal thin film layer is easily affected by oxygen and moisture in the atmosphere and its characteristics are easily deteriorated, conventionally, a thermoplastic resin or an ultraviolet curable resin containing an acrylic ester as a main component has been used as an overcoating agent. However, the adhesiveness and moisture resistance are insufficient, and the metal thin film layer is corroded even in the environment resistance test.

Was prepared to obtain an overcoated optical disc. After leaving the film in a constant temperature and humidity chamber for 50 hours in the same manner as in Example 1, the surface of the recording film was observed. As a result, the entire surface of the recording film was corroded.
