Abstract

An object of the present invention is to provide a novel monolayer and multilayer film that can be employed also for use in interior and exterior members of vehicles, and that have excellent transparency, surface hardness, chemical resistance, and stain resistance such as lactic acid resistance and sunscreen resistance. The present invention is directed to a fluororesin film formed with (C) a fluororesin comprising (B) a fluorinated (meth)acrylic resin that contains a fluorine-containing alkyl(meth)acrylate polymer component; and a fluororesin-laminated acrylic resin film, wherein the fluororesin film layer is laminated on at least one face of a film layer comprising (A) an acrylic resin.
