Abstract: PROBLEM TO BE SOLVED: To provide a laminate film having a good surface flatness and high adhesion between a thermoplastic resin film and a heat resistant resin film and showing good heat resistance and solvent resistance. SOLUTION: A laminate film is manufactured by laminating a heat resistant resin layer containing a resin made of an polyamide acid with its imidization ratio of not less than 50% as a major component on at least one surface of a biaxially stretched thermoplastic resin film wherein the heat resistant resin layer is directly bonded to the surface of the biaxially stretched thermoplastic resin film.

Abstract: PROBLEM TO BE SOLVED: To provide a laminated polyester film which shows high bending strength for the small thickness and further, far outstanding tear resistance which generally tends to deteriorate when the elastic modulus of an ordinary film is high. SOLUTION: This laminated polyester film has a laminated coating film containing inorganic plate particles and a water-soluble or a water-dispersed resin as main constituted components formed at least on one of the faces of a polyester film. The elastic modulus of at least either of the long axial direction or the width direction of the film is 6 GPa or more.
