PROBLEM TO BE SOLVED: To provide a gas barrier polyester resin composition mainly containing a polyester resin and having solubility to general-purpose solvents such as ethyl acetate and methyl ethyl ketone, and excellent in gas barrier property such as water vapor barrier property and oxygen barrier property, and to provide a gas barrier film obtained by coating a film with the resin composition, and a gas barrier film laminate.SOLUTION: The gas barrier polyester resin composition contains polyester polyol and a curing agent. The polyester polyol 1) is a polycondensate mainly composed of ethylene glycol, glycerol, phthalic anhydride and/or orthophthalic acid and 2) has a mole ratio between glycerol and ethylene glycol in the range of 1:3 to 1:0.33. |
