<P>PROBLEM TO BE SOLVED: To provide an optical disc which can satisfactorily inhibit the deformation (warping) of the disc when a protective film is manufactured (cured) and when temperature and humidity are changed, has excellent corrosion resistance of a metal layer under high humidity condition and is inexpensively and easily manufactured. <P>SOLUTION: The optical disc is provided with the protective film formed by polymerizing a light-curable silicone resin containing a structure of a heat-resistant group skeleton or polymerizing a reactive monomer containing a light-curable ester modified (meth)acrylate resin and a heat resistant group skeleton. The optical disc is manufactured by applying a coating liquid, irradiating the applied coating liquid with light to form a protective film, and thereafter, subjecting the protective film to annealing treatment. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
