Abstract
Provided are a thermoplastic resin composition whereby gum formation is suppressed during manufacturing of a matte fluororesin molded article such as a film, and a fluorine-based matte film having excellent matte properties and chemical resistance, and a layered film. A thermoplastic resin composition (α) for a chemical-resistant matte film, comprising a fluorine-based resin (A), a matting agent (B) which is a thermoplastic resin insoluble in the fluorine-based resin (A), and a thermoplastic resin (C) soluble in the fluorine-based resin (A). A thermoplastic resin composition (β) containing the fluorine-based resin (A) and an acrylic matting agent (D) which is a thermoplastic resin, the content ratio of alkyl acrylate units with respect to 100% by mass of monofunctional monomer units in the monomer units constituting the matting agent (D) being 50-100% by mass, and the content ratio of other monofunctional monomer units being 0-50% by mass. A matte film molded from the abovementioned thermoplastic resin compositions. A layered film in which an acrylic resin is layered on the matte film.
