A polycarbonate resin film, which is prepared by molding a resin composition, which comprises 100 parts by weight of a polycarbonate resin (A), 0.10 to 0.18 parts by weight of an alkali metal or alkaline earth metal salt compound (B) of a perfluoroalkane sulfonic acid and 0.05 to 0.35 parts by weight of a silicone compound (C), wherein a main chain of the silicone compound (C) is branched and the film has:n (1) an average thickness of 200 to 500 μm, (2) a degree of haze of 5% or lower as measured according to the conditions specified in JIS K7105, and (3) a flame retardance of VTM-1 or VTM-0 at a thickness of 300 μm as measured according to the UL94 test specified by the Underwriters Laboratories (UL). The polycarbonate resin film of the present invention exhibits excellent flame retardance without using a flame retarding agent comprising a halogen or phosphorus and has extremely excellent environmental compatibility with no concern for generating a halogen containing gas during combustion. In addition the film has a high degree of clarity and contributes to make the assembly work more efficient, for example, by shortening the time requirement when the film is utilized as an electrical insulating film. |
