GAS BARRIER MULTILAYER BODY

摘要

Disclosed is a gas barrier multilayer body comprising a plastic base (I); a gas barrier layer (II) which is made of a gas barrier layer-forming coating material (C) containing a polyalcohol polymer (A) and a polycarboxylic acid polymer (B); and a resin layer (III) which is made of a resin coating material (F) containing a monovalent metal compound (D), or a monovalent metal compound (D) and a divalent or higher valent metal compound (E). In this gas barrier multilayer body, the gas barrier layer (II) is arranged on the plastic base (I) directly or via an anchor coat layer, and the resin layer (III) is arranged on the gas barrier layer (II).
