Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a coating material applicable even to packaging materials for foodstuffs and pharmaceuticals which require, in addition to excellent performances of rust prevention, corrosion prevention, decorative nature, and the like, high gas barrier properties through shielding various gases, such as oxygen, water vapor, and flavoring ingredients. SOLUTION: The gas barrier coating material is one in which the film forming component is a gas barrier coating material composition predominantly composed of a compound (A) containing an active hydrogen and an organic polyisocyanate compound (B). Characteristically the hardened coating film formed from the coating material composition contains 20 wt.% or more of xylylenediamine skeletal structure. COPYRIGHT: (C)2004,JPO&NCIPI
