[0225] [Oxygen-absorbing resin composition]

[0226] The oxygen-absorbing resin composition of this embodiment contains at least a polyester compound containing at least one member selected from the group consisting of structural units represented by the above general formulas (1) to (4), and a transition metal catalyst. A structural unit having a tetralin ring (hereinafter also simply referred to as "tetralin ring-containing polyester compound").

[0227]

[0228] The tetralin ring-containing polyester compound used in the oxygen-absorbing resin composition of the present embodiment contains at least one of the structural units represented by the above general formulas (1) to (4). In addition, the structural unit represented by the above-mentioned general formula (1) is preferably at least one selected from the group consisting of the structural units represented by the above-mentioned formulas (5) to (7). Here, "containing a structural unit" means that the compound has on...

no. 2 approach

[0308] A second embodiment of the present invention will be described below. It should be noted that, for the same content as the above-mentioned first embodiment, the repeated description here is omitted.

[0309] [Oxygen-absorbing multilayer body]

[0310] The oxygen-absorbing multilayer body of the present embodiment includes at least an oxygen-absorbing layer (layer A) formed of the oxygen-absorbing resin composition of the first embodiment and a resin layer (layer B) containing a thermoplastic resin.

[0311] The layer structure in the oxygen-absorbing multilayer body of this embodiment is not particularly limited, and the number and types of the oxygen-absorbing layer (layer A) and the resin layer (layer B) are not particularly limited. For example, it may be an A / B structure including one layer of A and one layer of B, or may be a three-layer structure of B / A / B including one layer of A and two layers of B. In addition, a five-layer structure of B1 / B2 / A / B2 / B1 including...

no. 3 approach

[0373] A third embodiment of the present invention will be described below. It should be noted that for the same content as the above-mentioned first and second embodiments, repeated description here is omitted.

[0374] [Oxygen-absorbing multilayer body]

[0375] The oxygen-absorbing multilayer body of this embodiment is a sealant layer (layer C) containing a thermoplastic resin, and an oxygen-absorbing resin composition composed of an oxygen-absorbing resin composition containing a tetralin ring-containing polyester compound and a transition metal catalyst. Layer (Layer A) and at least three layers of a gas barrier layer (Layer D) containing a gas barrier material are laminated. In addition, as in the above-mentioned first and second embodiments, the oxygen-absorbing multilayer body of this embodiment may have layers other than these three layers at arbitrary positions as necessary.

[0376] The oxygen-absorbing multilayer body of this embodiment can absorb oxygen in the c...

Abstract

Provided are: a novel oxygen-absorbing resin composition which is not sensitive to metal detectors, does not generate an odor after the absorption of oxygen and exhibits excellent oxygen absorption performance; an oxygen-absorbing molded body which uses this oxygen-absorbing resin composition; and a multilayer body, a container, an injection molded body, a medical container and the like, each of which uses the oxygen-absorbing resin composition or the oxygen-absorbing molded body. Also provided are: an oxygen-absorbing resin composition which exhibits excellent oxygen absorption performance over a wide range of humidity conditions from low humidity to high humidity; and the like. An oxygen-absorbing resin composition of the present invention contains a polyester compound and a transition metal catalyst, and the polyester compound contains at least one constituent unit that has a tetralin ring. An oxygen-absorbing molded body of the present invention is obtained by molding the oxygen-absorbing resin composition into a film form or a sheet form. A multilayer body, container, injection molded body, medical container and the like of the present invention are obtained using the oxygen-absorbing resin composition of the present invention.
