Title:
MULTILAYER FILM AND MOLDED BODY
Document Type and Number:
WIPO Patent Application WO/2011/136042
Kind Code:
A1
Abstract:
Disclosed is a multilayer film which has a layer A on at least one surface of a base film and is characterized in that: 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 point of from -30˚C to 0˚C. Also disclosed is a multilayer film which has a layer A on at least one surface of a base film and is characterized in that the layer A has the above-mentioned (1)-(3) and a scratch recovery time at a temperature of 10˚C of 3 seconds or less. Further disclosed is a multilayer film which has a layer B on at least one surface of a base film and is characterized in that the layer B has the above-mentioned (1) and (3) and an average elongation at break over the range from 80˚C to 150˚C of 65% or more. The multilayer films have excellent conformability and self-healing properties during molding and excellent self-healing properties at low temperatures, and can be used in applications where moldability and self-healing properties are required at the same time.
