NOVELTY - A gas-barrier laminated film has a gas barrier layer provided on one or both surfaces of laminate of a primary layer having tensile elasticity modulus of 80% or less and a secondary layer having glass transition temperature of 300 degrees C or more. The thickness ratio of secondary layer and primary layer is 0.01-5. The primary layer consists of a curable resin composition containing curable resin having cage-type silsesquioxane structure. The secondary layer consists of curable resin composition containing curable resin with cage-type silsesquioxane structure.    USE - Gas barrier laminated film. Uses include but are not limited to display substrate for liquid crystal display elements, substrate for color filters, plastic substrate for organic electroluminescent display element, substrate for electronic paper, solar cell substrate, plasma display, etc.    ADVANTAGE - The gas barrier laminate film has excellent transparency, heat resistance, impact resistance, dimensional stability, and gas barrier property.    DETAILED DESCRIPTION - A gas-barrier laminated film has a gas barrier layer provided on one or both surfaces of laminate of a primary layer having tensile elasticity modulus of 80% or less and a secondary layer having glass transition temperature of 300 degrees C or more. The thickness ratio of secondary layer and primary layer is 0.01-5. The primary layer consists of a curable resin composition containing curable resin having cage-type silsesquioxane structure. The primary layer has tensile elasticity modulus of 2000-10000 MPa in a tensile-stress distortion curve and linear expansion coefficient of 80 ppm/K or less. The secondary layer has a plastic deformation property, consists of curable resin composition containing curable resin with cage-type silsesquioxane structure, and has tensile elasticity modulus of 100 MPa or more in tensile stress distortion curve. An INDEPENDENT CLAIM is included for manufacture of gas barrier laminated film, which involves obtaining two hardened material using curable resin composition by photocuring such that functional group consumption rate of resin in the composition is 50-90%, preferably 50-85%, forming secondary layer, inserting and photocuring curable resin composition which forms primary layer between two obtained hardened materials, obtaining laminated film, and providing gas barrier layer on one or both surfaces of laminated film with a roll to roll system.
