Zusammenfassung: | Provided is a vinylidene fluoride-based resin multi-layered film, which can suppress the discoloration of the film caused by acid rain and the discoloration of the film caused by the production of a polyene structure by a hindered amine-based light stabilizer included in a decorative film, in a high-humidity environment for a long time period.Disclosed is a vinylidene fluoride-based resin multi-layered film including two layers composed of a front surface layer laminated on a rear surface layer, in which the front surface layer contains 80% by mass or more of a vinylidene fluoride-based resin and 20% by mass or less of a methacrylic acid ester-based resin, the degree of crystallization of the front surface layer is 45% or higher, the ratio occupied by α-crystals in the entire crystal component of the vinylidene fluoride-based resin is 60% or higher, the thickness of the front surface layer is 15 µm or more, and the rear surface layer contains 90% by mass or more of a methacrylic acid ester-based resin. |
