Abstract:
Disclosed is a fluorine-containing resin film which is formed from a fluorine-containing resin composition and has a thickness of 10 to 50 μm, wherein the fluorine-containing resin composition is prepared by adding 10 to 30 parts by mass of titanium oxide or a composite-oxide-type inorganic pigment to 100 parts by mass of a resin component comprising 60 to 95 parts by mass of a vinylidene fluoride resin and 5 to 40 parts by mass of a methacrylic acid ester resin, and wherein the peak intensity ratio of a II-type crystal, which is expressed by (A)/((A)+(B))×100 wherein A represents the peak height at 840 cm−1 and B represents the peak height at 765 cm−1 in a measurement chart produced by an infrared absorption spectrum, is 60% or more and the total crystallinity is 30% or more as calculated from an X-ray diffraction profile.
