Abstract
Provided is a thermoplastic resin film having at least one of film surfaces being excellent in printability, having sufficiently low internal haze, and exhibiting a favorable matte appearance. A thermoplastic resin film according to the present invention composed of a thermoplastic resin composition (C) including at least one kind of a thermoplastic resin (R) and fine particles (P) having a volume average particle diameter of 0.5 to 15 μm and a refractive index different from that of the thermoplastic resin (R) by 0.02 or more.At least one of film surfaces satisfies formulas (1) and (2). GL≥60 (1),GL−35≤GH≤GL−10 (2) (In the formulas (1) and (2), GL is 60° gloss (%) at 20° C., GH is 60° gloss (%) when the thermoplastic resin film is heated at a temperature 10° C. higher than a glass transition temperature of the thermoplastic resin composition (C) for 30 minutes, then cooled to 20° C.).
