<P>PROBLEM TO BE SOLVED: To provide a releasing film which has an excellent heat resistance and dimensional stability and can be produced at a lower cost, an active energy ray-curable film obtained by forming and hardening an active energy ray-curable composition layer using the same film as a releasing film and an optical disk formed by using the active energy ray-curable film. <P>SOLUTION: The releasing film comprising a single layer or two or more layers of laminate comprises at least one layer of polycarbonate resin, characterized in that a releasing layer forming a releasing surface is a layer of a release agent, a polycarbonate resin layer, or polycarbonate resin layer added with the release agent, the active energy ray-curable film is obtained by using the releasing film, and the optical disk is obtained by using the film. <P>COPYRIGHT: (C)2007,JPO&INPIT |
