Abstract: Provided are a gas barrier resin composition, and a gas barrier composite film excellent in gas barrier properties with respect to oxygen, carbon dioxide gas, water vapor or the like, particularly in gas barrier properties even after hot water treatment. The gas barrier resin composition includes an oxazoline group-containing aqueous polymer (A), an aqueous acrylic resin (B) and/or an aqueous polyester resin (C) each at a specific concentration, wherein the ratio of the mole number of the oxazoline group to the mole number of the carboxyl group [the ratio of the mole number of the oxazoline group (x mmol) to the mole number of the carboxyl group (y mmol), which is indicated as (x/y)×100 (mol %)], is within the specific range. The gas barrier composite film uses this composition.

Abstract: A laminate film includes a substrate layer; and a metal oxide layer which is provided on one surface or both surfaces of the substrate layer and contains a metal oxide. Further, the oxygen permeability measured under defined conditions is 20 ml/m2·day·MPa or less and the water vapor permeability measured under conditions of a temperature of 40° C. and a humidity of 90% RH is 2.5 g/m2·day or greater. In addition, when the Kα beam intensity of a metal constituting the metal oxide which is obtained by performing fluorescence X-ray analysis on the metal oxide layer is set to A and the Kα beam intensity of the metal which is obtained by performing fluorescence X-ray analysis on a metal layer formed of the metal constituting the metal oxide is set to B, A/B is equal to or greater than 0.20 and equal to or less than 0.97.
