| description | PROBLEM TO BE SOLVED: To provide an adhesive which can be used for food packaging and is mainly composed of polyester polyol excellent in gas barrier property, and to provide a gas barrier hardener resin composition used for the adhesive.SOLUTION: The gas barrier hardener resin composition contains a polyester polyol having two or more hydroxyls in one molecule as a functional group and an isocyanate compound, in which the permachor value of residues except terminal hydroxyls of the polyester is in the range of 44 to 60. A gas barrier hardener obtained by hardening the composition has a permachor value per mole of 50 or more. This gas barrier hardener can be used as an adhesive excellent in gas barrier property and solubility to ethyl acetate that is an all-purpose solvent. A multilayer film obtained using the adhesive is excellent in gas barrier property. |
