A laminated body having a thermoplastic resin layer (I) and a polyamide resin layer (II) which is made of nylon 11 and/or nylon 12. The thermoplastic resin layer (I) includes 100 parts by weight of a polyamide resin composition (A) and 0.1 to 10 parts by weight of a carbodiimide compound (B) having two or more carbodiimide groups. The polyamide resin composition (A) contains a polyamide resin (a-1) having diamine units 70 mol % or more of which are derived from m-xylylenediamine and dicarboxylic acid units 70 mol % or more of which are derived from a C4 to C20 α,ω-linear aliphatic dicarboxylic acid and a nylon 12 and/or nylon 11 component (a-2) in an amount of 5 to 95% by weight of the component (a-1) and 95 to 5% by weight of the component (a-2) each based on a total weight of the components (a-1) and (a-2). The laminated body is excellent in the barrier property, peeling resistance and mechanical properties such as strength, impact resistance and elongation, particularly in the barrier property to alcohol-containing fuels.
A laminated body comprising a thermoplastic resin layer (I) and a polyamide resin layer (II) which comprises nylon 11 and/or nylon 12, the thermoplastic resin layer (I) comprising 100 parts by weight of a polyamide resin composition (A) and 0.1 to 10 parts by weight of a carbodiimide compound (B) having two or more carbodiimide groups, the polyamide resin composition (A) comprising a polyamide resin (a-1) which is constituted by diamine units 70 mol % or more of which are derived from m-xylylenediamine and dicarboxylic acid units 70 mol % or more of which are derived from a C4 to C20 α,ω-linear aliphatic dicarboxylic acid and a nylon 12 and/or nylon 11 (a-2) in an amount of 5 to 95% by weight of the component (a-1) and 95 to 5% by weight of the component (a-2) each based on a total weight of the components (a-1) and (a-2).
