Abstract

An oxygen-absorbing resin composition including a base resin (A) which is a thermoplastic resin, an oxygen-absorbing component (B) which is a compound having an unsaturated alicyclic structure, and an oxidation promotion component (C) for promoting the oxidation of the oxygen-absorbing component (B); wherein the oxygen-absorbing component (B) is an imide compound having a molecular weight of not more than 2,000 and obtained by heat-treating an amide having been obtained by reacting an acid anhydride represented by the following formula (1): wherein the ring X is an alicyclic ring having an unsaturated bond, and Y is an alkyl group, with an aromatic amine, and wherein the oxidation promotion component (C) is a compound having a benzyl hydrogen.
