WIPO Patent Application WO/2018/221580

A1

Provided is a layered film that is suitable for use in film insert molding. This layered film (10) includes a surface layer (11) that contains a methacrylic resin (A) and a binder layer (12) that contains a thermoplastic resin (B), and satisfies (formula 1) to (formula 3). Formula 1: HDa < HDb. Formula 2: Tb/T < 0.5. Formula 3: 25 ≤ C/Ta ≤ 100. Deflection temperature under load of constituent material of surface layer: HDa. Deflection temperature under load of constituent material of binder layer: HDb. Overall thickness of layered film: T (mm). Thickness of surface layer: Ta (mm) (here Ta = 0.05-0.35 mm). Thickness of binder layer: Tb (mm). Concentration of C6-12 alkyl acrylate ester units in constituent material of surface layer: C (mass%).
