Provided is a laminated polyester film that exhibits excellent scratch recovery and contamination resistance and suits a molding application. A laminated film having a layer (A) on at least one side of a base film, wherein the resin contained in the layer (A) has (1) a (poly)caprolactone segment and (2) a urethane bond, and, in measurement using a micro hardness tester, the maximum displacement amount in the thickness direction of the layer (A) is 1.0 to 3.0 µm and the creep displacement amount in the thickness direction of the layer (A) is 0.2 to 0.5 µm when a load of 0.5 mN is applied for 10 seconds, and the permanent displacement amount in the thickness direction of the layer (A) is 0.3 to 0.65 µm when the load is released to 0 mN.

In view of the above-described problems in the prior art, an object of the present invention is to provide an ornamental film which reflects an image on the surface of the film with high image clarity and having a deep and glossy jet-black color like the outer appearance of pianos. The film is a multilayered film comprising at least one resin layer (A layer) containing a black component; and at least one substantially colorless and transparent resin layer (B layer); the A layer having a thickness of not less than 20 µm and not more than 300 µm; the B layer having a thickness of not less than 0.5 µm and not more than 200 µm; the A layer and the B layer being arranged adjacently to each other; surface roughness Ra of at least one side surface of the film being not less than 1 nm and not more than 25 nm.

An object of the present invention is to provide a film having a high brightness and a natural metal-effect, and also having excellent formability, causing no delamination and maintaining the metal-effect after forming. Another object is to provide a molded body having less environmental burden, excellent in recycling efficiency and giving no electromagnetic interference. A laminated film including a structure where each 30 layers or more of a layer composed of a resin A (A layer) and a layer composed of a resin B (B layer) are alternately laminated, wherein a relative reflectance in a wavelength range of 400 nm to 1000 nm is 30% or more, tensile stresses at 100% elongation in a longitudinal direction and a width direction of the film are 3 MPa or more and 90 MPa or less in a tensile test at 150°C, and the number of layers with a layer-pair thickness of 10 nm or more and less than 220 nm is more than the number of layers with a layer-pair thickness of 220 nm or more and 320 nm or less.

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.
