A laminated film has a layer (A) on at least one side of a base film, wherein 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, a maximum displacement amount in a thickness direction of the layer (A) is 1.0 to 3.0 &#x3bc;m and a creep displacement amount in the thickness direction of the layer (A) is 0.2 to 0.5 &#x3bc;m when a load of 0.5 mN is applied for 10 seconds, and a permanent displacement amount in the thickness direction of the layer (A) is 0.3 to 0.65 &#x3bc;m when the load is released to 0 mN.

Laminated film

A laminated film includes a substrate film and layer A provided at least on one side thereof, layer A containing (1) a (poly)caprolactone segment and (2) a urethane bond, wherein a distilled water contact angle on layer A and a diiodomethane contact angle on layer A are 95&#xb0; or more, but less than 120&#xb0; and 70&#xb0; or more, but less than 87&#xb0;, respectively.

Laminated film and molded body

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 &#x2212;30 to 0&#xb0; 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&#xb0; 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&#xb0; C. to 150&#xb0; C.

Multilayer film and molded body

A glass protecting film including at least 5 or more layers, of which at least one layer is the layer which comprises polyester having 1,4-cyclohexane dimethanol is one of the components, and a glass protecting including a multi-layer structure which comprises at least two kinds of thermoplastic resin, of which the difference of glass transition temperature is 40&#xb0; C. or less, the face-impact strength is 18 J/mm or more, haze is 3% or less, are films which excel in transparency, tear resistance, and impact resistance, and are suitable for protecting glass and preventing damaged glass fragments.

Protective film for glass

A glass protecting film comprising at least 5 or more layers, of which at least one layer is the layer which comprises polyester having 1,4-cyclohexane dimethanol is one of the components, and a glass protecting comprising a multi-layer structure which comprises at least two kinds of thermoplastic resin, of which the difference of glass transition temperature is 40&#xb0; C. or less, the face-impact strength is 18 J/mm or more, haze is 3% or less, are films which excel in transparency, tear resistance, and impact resistance, and are suitable for protecting glass and preventing damaged glass fragments.
