GAS-BARRIER MATERIAL AND PROCESS FOR PRODUCING THE SAME

摘要

A gas-barrier material which comprises a resin obtained from a resin having carboxy groups in an amount corresponding to an acid value of 580 mg-KOH/g or higher by ionically crosslinking the carboxy groups in an amount corresponding to an acid value of at least 330 mg-KOH/g. This material is excellent in gas-barrier properties under high-humidity conditions, suitability for retortion, and flexibility. A coating film can be cured at a low temperature in a short time. The gas-barrier material is excellent also in productivity.
