BIAXIALLY ORIENTED LAMINATED POLYESTER FILM

摘要

PROBLEM TO BE SOLVED: To provide a biaxially oriented laminated polyester film which is prevented from the deposition of a dye to the film surface is excellent in adhesion to a heat-insulating layer or a hard coat layer and in heat insulating properties and designability, and is suitable as a film to be pasted on a window. SOLUTION: This biaxially oriented laminated polyester film is a co-extrusion laminated film comprising at least three polyester layers and contains a substantially polyester-soluble dye in the intermediate layer. A film made of a metal or a metallic oxide is laminated on at least one of the film surfaces. COPYRIGHT: (C)2003,JPO
