PROBLEM TO BE SOLVED: To provide a new oxygen-absorptive multilayer body which has not only excellent oxygen absorption performance but also good molding processability and a small oxygen permeability coefficient, from the oxygen-absorbed one of which an odor is not emitted but which has excellent oxygen absorption performance under a wide humidity condition of low humidity to high humidity.SOLUTION: The oxygen-absorptive multilayer body has an oxygen absorption layer containing an oxygen-absorptive composition and a thermoplastic resin layer containing a thermoplastic resin. The oxygen-absorptive composition contains, at the least, a polyester compound containing a constituent unit having at least one tetralin ring, a transition metal catalyst, and an ethylene-vinyl alcohol copolymer.COPYRIGHT: (C)2014,JPO&INPIT【課題】優れた酸素吸収性能を有するのみならず、成形加工性が良好で酸素透過係数が小さい、新規な酸素吸収性多層体等を提供する。また、本発明の他の目的は、酸素吸収後の臭気発生が無く、低湿度から高湿度までの広範な湿度条件下で優れた酸素吸収性能を有する、酸素吸収性多層体等を提供する。【解決手段】酸素吸収性組成物を含有する酸素吸収層と熱可塑性樹脂を含有する熱可塑性樹脂層と有し、前記酸素吸収性組成物が、少なくとも1つのテトラリン環を有する構成単位を含有するポリエステル化合物と遷移金属触媒とエチレン-ビニルアルコール共重合体とを少なくとも含む、酸素吸収性多層体。【選択図】なし
