Title:
積層フィルムおよび成型体
Document Type and Number:
Japanese Patent JP5799806
Kind Code:
B2
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.
