    • A first multilayer film 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 contains a layer A on at least one surface of a base film, in which the layer A has a scratch recovery time of 3 seconds or less at a temperature of 10° C. A third multilayer film 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.
