Abstract: A barrier laminate film (100) of the present invention includes: a base material layer (101), a stress relaxation layer (102), an inorganic material layer (103), and a barrier resin layer (104) in this order. The barrier resin layer (104) includes an amide cross-linked compound of a polycarboxylic acid and a polyamine, and the stress relaxation layer (102) includes a polyurethane-based resin having an aromatic ring structure in a main chain.

Abstract: 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 cm−1 and a measurement point at 1780 cm−1 is set as a baseline, an absorption intensity at 1660 cm−1 is set as I(1660), and an absorption intensity at 1625 cm−1 is set as I(1625), R represented by Equation (1) is greater than 1. R=I(1660)/I(1625)−{−0.65×(total amine/COOH)+0.4225}  (1)
