Abstract: An aqueous dispersion comprising a dispersoid of an ethylene-vinyl alcohol copolymer having an ethylene content of 15 to 65 mole % and a dispersion stabilizer of a saponified product of an ethylene-vinyl ester copolymer having an ionic group and having an ethylene content of 10 to 70 mole % and a saponification degree of at least 80%. According to the present invention, aqueous dispersions with high solid concentration and having excellent stability during storage or upon use. The film obtained by applying and then drying the aqueous dispersion has excellent gas barrier properties.
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.
