    Abstract: A first multilayer film of the invention is a multilayer film which contains a layer A on at least one surface of a base film, in which the layer A has (1) a polycaprolactone segment, (2) a polysiloxane segment and/or a polydimethyl siloxane segment, and (3) a urethane bond, and the layer A has a glass transition temperature of from -30 to 0°C. A second multilayer film of the invention is a multilayer film which contains a layer A on at least one surface of a base film, in which the layer A has (1) a polycaprolactone segment, (2) a polysiloxane segment and/or a polydimethyl siloxane segment, and (3) a urethane bond, and the layer A has a scratch recovery time of 3 seconds or less at a temperature of 10°C. A third multilayer film of the invention is a multilayer film which contains a layer B on at least one surface of a base film, in which the layer B has a polycaprolactone segment and a urethane bond, and the layer B has average elongation at break of 65% or more at 80°C to 150°C. The multilayer film of the invention has excellent conformability and self-healing property during molding and excellent self-healing property at low temperatures. Thus, the multilayer film of the invention can be used in applications where moldability and self-healing property are required at the same time.

    Abstract: A multilayer film of which the optical properties hardly change due to heat and where detachment hardly occurs between layers is provided. In addition, a multilayer film which is appropriate for decorative materials used as construction materials, wrapping, the interior and exterior of automobiles and the like, anti-counterfeit materials, for example holograms, various types of displays, such as liquid crystal displays, plasma displays, field emission displays and organic electronic displays, reflective materials and optical filters for optical devices, such as optical printing devices, cameras and the like, heat ray blocking window films for automobiles and construction materials, and reflectors for solar batteries is provided. A multilayer film is provided with a structure where five or more layers made of thermoplastic resin A (layers A) and five or more layers made of thermoplastic resin B (layers B) having a basic skeleton that is the same as that of thermoplastic resin A are alternately layered on top of each other, and is characterized in that at least one reflection peak is provided and the difference between the reflectance of the reflection peak before heating and after heating for 30 minutes in an atmosphere of 150°C is no greater than 15%.
