Patent ID: 7560168

Claim:
A gas barrier laminate film comprising: a resin substrate; a gas barrier vapor deposition layer formed on the resin substrate and mainly containing an inorganic compound; and a gas barrier covering layer formed on the gas barrier vapor deposition layer; wherein the gas barrier covering layer is formed through the coating, and drying of a coating liquid which comprises: one of materials selected from a silicon compound represented by a general formula of Si(OR 1 ) 4 . . . (1) and the hydrolyzates thereof; one of materials selected from a silicon compound represented by a general formula of (R 2 Si(OR 3 ) 3 ) n . . . (2) and the hydrolyzates thereof (wherein R 1 and R 3 are individually CH 3 , C 2 H 5 or C 2 H 4 OCH 3 ; and R 2 is an organic functional group consisting of isocyanate); and a water-soluble polymer having hydroxyl group.
