た積層体に関する。DETAILED DESCRIPTION OF THE INVENTION A. The present invention provides an adhesive resin composition and, through the adhesive resin composition, a gas barrier resin, particularly a saponified ethylene-vinyl acetate copolymer resin, and a hydrophobic heat-resistant resin. The present invention relates to a laminate in which plastic resins are laminated.

り、代替包装置¥器材料の開発がまたれている。For example, it is well known that hydrophobic thermoplastic resins such as saturated polyester are being used for food packaging for the purpose of reducing weight for hygiene, aesthetic appearance, and reduced transportation costs. However, these saturated polyester resins have poor barrier properties against oxygen and carbon dioxide, making them unsuitable for long-term storage of foods, carbonated drinks, etc. Glass bottles and metal cans are often used, and empty cans are stored on the street. There are many problems, such as the pollution caused by throwing bottles into the water and the cost required to collect the bottles, and efforts are being made to develop alternative packaging materials.

があり、充分満足すべきものではない。Saponified ethylene-vinyl acetate copolymer resin with an ethylene content of 20 to 55 mol% has excellent properties as a material for food containers and packaging materials as it is melt moldable, highly transparent, and has excellent gas barrier properties. Prepared. However, it has drawbacks in other physical properties, such as rigidity and moisture resistance, and is not fully satisfactory.

ある。On the other hand, hydrophobic thermoplastic resins, especially saturated polyester resins whose main component is polyethylene terephthalate, are excellent in moldability, balance between I4wR impact resistance and rigidity, and hygienic properties; - is not sufficient, and there are restrictions on its use as food containers and packaging materials.

て積層物を得ることは不可能である。Therefore, in order to obtain food containers and packaging materials that have both the good gas barrier properties of saponified ethylene-vinyl acetate copolymer resins and the excellent mechanical properties of hydrophobic thermoplastic resins such as saturated polyester resins, we have developed both these materials. It is conceivable to laminate several resins. However, these resins have little affinity with each other, and it is impossible to obtain a laminate by mere thermal bonding.

その有用性を主張している。It is known in JP-A-55-71556 that a polymer consisting of an ethylene component - an acrylic ester component or a vinyl acetate component - an ethylenically unsaturated carboxylic acid or the carboxylic acid anhydride component and a saturated polyester resin have adhesive properties. be. The publication describes copolymers of ethylene and carboxyl group-containing monomers, such as ethylene-vinyl acetate copolymers, ethylene-acrylic ester copolymers, and ethylene-acrylic ester copolymers, with ethylenically unsaturated carboxylic acids. Alternatively, it is shown that a modified ethylene-carboxyl group-containing monomer copolymer to which the carboxylic acid anhydride is chemically bonded can adhere to a saturated polyester resin,
It claims its usefulness.

いる。Furthermore, in JP-A-54-101883, a thermoplastic resin and a saponified ethylene-vinyl acetate copolymer resin are mixed into a copolymer of ethylene and a monomer containing a carboxyl group, and an ethylenically unsaturated carboxylic acid or the carboxylic acid anhydride is added to the copolymer of ethylene and a monomer containing a carboxyl group. This shows that a chemically bonded modified ethylene-carboxyl group-containing monomer copolymer can be laminated as an intermediate layer. Furthermore, in JP-A-54-110282, an ethylenically unsaturated carboxylic acid or an anhydride of the carboxylic acid is chemically bonded to a copolymer of ethylene and a monomer containing a carboxyl group, and a metal oxide or carbonate is bonded to the copolymer. A laminated structure containing a saponified ethylene-vinyl acetate copolymer resin is obtained using the reacted metal bond modified copolymer as an adhesive layer.

ある物は得られない。However, in the combination of a saponified ethylene-vinyl acetate copolymer resin and a hydrophobic thermoplastic resin such as a saturated polyester resin containing polyethylene terephthalate as a main component, the ethylene component - the acrylic ester component or the lower fatty acid vinyl ester component - When a copolymer consisting of an ethylenically unsaturated carboxylic acid or carboxylic acid anhydride component, or a resin made by reacting the copolymer with a metal oxide or carbonate, is used for the adhesive resin layer, a certain degree of adhesion is achieved. However, the resulting molded product has poor appearance mainly due to uneven thickness of the gas barrier resin layer and the occurrence of streaks, bumps, and wavy patterns that are thought to be caused by the formation of gelled products. Products with commercial value such as laminates cannot be obtained.

る。Zarani Japanese Patent Publication No. 39-6810 describes a copolymer obtained from one or more α-olefins and one or more α, β-ethylenically unsaturated carboxylic acids having one or two carboxyl groups. A method for producing an ionic copolymer by reacting an ionic metal compound that can be dissolved in water is known. Therein, the preferred base copolymer is one in which ethylene is copolymerized directly with a monocarboxylic acid monomer, with or without the presence of a third copolymerizable monoethylenically unsaturated monomer. is said to be suitable. By neutralizing 10% or more of the acid groups with metal ions such as Na+, the base copolymer has rubber elasticity, flexibility,
It has been demonstrated that it has both desirable physical properties in the solid state, such as thermal stability, toughness, and wear resistance, as well as melt fluidity, and claims its superiority. On the other hand, it has been disclosed that the base copolymer can also be obtained by graft polymerizing an α-olefin and an acid type polymer onto a polyolefin base, but this method is not suitable for olefins having a molecular weight larger than ethylene, such as propylene. , butene-1, etc., and there is no disclosure that ethylene-acrylic acid ester or vinyl acetate copolymer can be used as the polyolefin. The invention improves the above-mentioned physical properties in resins with a melting index (MI) h < 0.1 to 100 g/lo, and only bonds when the melting index (MI) is 100 g/10 minutes or more. It has been shown that it can be used as a resin for adhesives and laminated products.

An ionic copolymer prepared by reacting one or more water-soluble ionic metal compounds exhibits no adhesive properties regardless of the presence or absence of an acrylic ester or vinyl acetate component. Furthermore, a resin made of a polyolefin obtained from propylene, butene-1, etc. as a base copolymer, grafted with an acid type polymer, and neutralized with metal ions shows no adhesive properties at all. Furthermore, when the MI is 100 g/10 minutes or more, there is a problem that molding cannot be performed because the MI is too large. Therefore, it cannot be used as a substantially useful adhesive resin.

であり、驚くべきである。This means that a modified ethylene-carboxylic acid is produced by chemically bonding an ethylenically unsaturated carboxylic acid or the carboxylic acid anhydride to a copolymer of ethylene and a carboxyl group-containing monomer such as acrylic acid ester, vinyl acetate, or methacrylic acid ester. A group-containing monomer copolymer or a metal bond-modified copolymer obtained by reacting the copolymer with a metal oxide or carbonate exhibits adhesive properties with saponified ethylene-vinyl acetate copolymer resin, saturated polyester resin, etc. This is surprising because it was completely unexpected based on the well-known technology that improves the solid state using metal ions.
