[PROBLEMS] To form a gas barrier material having excellent gas barrier properties, retort resistance, and flexibility, and to enable curing at a lower temperature in a shorter time, without affecting the plastic substrate and improving productivity. The object is to provide a composition for forming a gas barrier material that can be improved. An ether bond is formed on carbon forming a double bond between a polycarboxylic acid polymer (A) and nitrogen, and at least a ring structure (b) containing oxygen in the ether bond is formed. A gas barrier material-forming composition comprising two compounds (B) and a dehydrating agent (C). [Selection figure] None |
