摘要:
A gas barrier layered product and a method for producing the same are provided. The gas barrier layered product exhibits a high oxygen barrier property regardless of humidity, exhibits a high oxygen barrier property even after being subjected to retort processing, and is excellent in strength and transparency. In order to provide the gas barrier layered product, the gas barrier layered product includes a base material and a layer stacked on at least one surface of the base material. The layer is formed of a composition that includes: a hydrolyzed and condensed product of at least one compound (L) containing a metal atom to which at least one characteristic group selected from a halogen atom and an alkoxy group has been bonded; and a neutralized product of a polymer containing at least one functional group selected from a carboxyl group and a carboxylic anhydride group. At least a part of the —COO— group contained in the at least one functional group has been neutralized with metal ions having a valence of two or more.
