<P>PROBLEM TO BE SOLVED: To provide a rolled gas barrier laminate film which is excellent in transparency, heat resistance, impact resistance, dimensional stability and gas barrier property, and a method for manufacturing the same. <P>SOLUTION: The gas barrier laminate film includes: a first layer composed of a hardening resin composition including a hardening resin having a cage-type silsesquioxane structure, the first layer having a tensile elastic modulus in a tensile stress-strain curve of ≥2,000 MPa and ≤10,000 MPa, a linear expansion coefficient of ≤80 ppm/K and a glass transition temperature of ≥300°C; and a second layer composed of a hardening resin composition including a hardening resin having a cage-type silsesquioxane structure, the second layer having a tensile elastic modulus in tensile stress-strain curve of ≥100 MPa, which is ≤80% of the tensile elastic modulus of the first layer, showing plastic deformation, and having a glass transition temperature of ≥300°C, in which the first layer and the second layer are laminated in a thickness ratio (the thickness of the second layer÷the thickness of the first layer) of ≥0.01 and ≤5.0, and a gas barrier layer is provided on one surface or both surfaces of the laminate film. <P>COPYRIGHT: (C)2012,JPO&INPIT |
