Abstract An adhesive resin composition useful for bonding a resin having gas barrier properties and a hydrophobic thermoplastic resin which comprises an ethylene-acrylate or methacrylate copolymer grafted with an ethylenic unsaturated carboxylic acid or its acid anhydride; and 0.02 to 0.6 equivalent to the ethylenic unsaturated carboxylic acid or its acid anhydride of a periodic table group Ia or IIa metal hydroxide, or said metal hydroxide and an ethylene-acrylate or methacrylate copolymer. A laminated material of a resin having gas barrier properties and a hydrophobic thermoplastic resin laminated with the adhesive resin composition and a resin composition comprising the adhesive resin composition, a resin having gas barrier properties and a hydrophobic thermoplastic resin are also disclosed.
An adhesive composition which comprises (a) metal containing composition consisting of (i) an ethylene-acrylate or methacrylate copolymer containing from 5 to 45% by weight acrylate or methacrylate component content, said copolymer being grafted with 0.01 to 6% by weight of an ethylenic unsaturated carboxylic acid or its acid anhydride; and (ii) 0.02 to 0.6 equivalent of the ethylenic unsaturated carboxylic acid or its acid anhydride of a periodic table Group Ia or IIa metal hydroxide; or (b) a blend of said metal containing composition (a) with ethylene-acrylate or methacrylate copolymer wherein said metal containing composition (a) constitutes 1-60% by weight of said blend.
