| description | PROBLEM TO BE SOLVED: To provide an EVOH resin composition, which has good coloring resistance and heat resistance at high temperatures and good adhesion with thermoplastic resin compositions, and can provide a multilayer structure with good appearance, and the multilayer structure containing the composition layer.SOLUTION: The composition contains (A) an EVOH resin, (B) an alkaline earth metal, (C) an alkali metal, and (D) a 2 to 4C carboxylic acid, which satisfies requirement (α): the content of the (B) alkaline earth metal in the EVOH resin (A) is more than 10 to 50 ppm, requirement (β): the content ratio (C/B) of the alkali metal (C) to the alkaline earth metal (B) ranges from 0.001 to 0.5, and requirement (γ): the content ratio (D/B) of the 2-4C carboxylic acid (D) to the alkaline earth metal (B) ranges from 5 to 30. |
