A gas barrier polymer is formed by heat-curing a mixture including polycarboxylic acid and a polyamine compound, in which, in an infrared absorption spectrum, when a straight line connecting a measurement point at 1493 cmand a measurement point at 1780 cmis set as a baseline, an absorption intensity at 1660 cmis set as I(1660), and an absorption intensity at 1625 cmis set as I(1625), R represented by Equation (1) is greater than 1.R=I(1660)/I(1625)&#x2212;{&#x2212;0.65&#xd7;(total amine/COOH)+0.4225}&#x2003;&#x2003;(1)

Gas barrier polymer and gas barrier laminate using same

A barrier laminate film () of the present invention includes: a base material layer (), a stress relaxation layer (), an inorganic material layer (), and a barrier resin layer () in this order. The barrier resin layer () includes an amide cross-linked compound of a polycarboxylic acid and a polyamine, and the stress relaxation layer () includes a polyurethane-based resin having an aromatic ring structure in a main chain.
