PROBLEM TO BE SOLVED: To provide a gas barrier aluminum vapor deposition film having breaking properties to gas such as oxygen and water vapor, printable and having boil resistance.SOLUTION: Provided is a gas barrier vapor deposition film in which an anchor vapor deposition layer, an aluminum vapor deposition layer and a gas barrier resin layer are successively laminated at least on one side of a polyester film base material, in which the coating amount of the anchor vapor deposition layer is 80 to 120 ng/cm, the surface resistance value of the aluminum vapor deposition layer is 0.1 to 3.0 &OHgr;/sq, the gas barrier resin layer is composed of the main agent consisting of a copolymer using the three components of: (a) unsaturated nitrile of 10 to 30 wt.% in a ratio occupied in the copolymer; (b) an unsaturated compound having a hydroxyl group of 30 to 70 wt.% in a ratio occupied in the copolymer; and (c) unsaturated carboxylic ester of 20 to 60 wt.% in a ratio occupied in the copolymer and a curing agent composed of a compound having an isocyanate group. |
