GAS BARRIER COATING MATERIAL, GAS BARRIER FILM, GAS BARRIER LAMINATE, AND METHOD FOR PRODUCING GAS BARRIER LAMINATE

WIPO Patent Application WO/2021/132127

A1

This gas barrier film is constituted from a cured product of a mixture containing a polycarboxylic acid, a polyamine compound and a polyvalent metal compound. In an infrared absorption spectrum of the gas barrier film, if A denotes the total peak area within an absorption band of 1493 cm-1 - 1780 cm-1, B denotes the total peak area within an absorption band of 1598 cm-1 - 1690 cm-1, C denotes the total peak area within an absorption band of 1690 cm-1 - 1780 cm-1 and D denotes the total peak area within an absorption band of 1493 cm-1 - 1598 cm-1, the amide bond area ratio represented by B/A is 0.380 or less, the carboxylic acid area ratio represented by C/A is 0.150 or less, and the carboxylate area ratio represented by D/A is 0.520 or more.
