Disclosed is an oxygen-absorbing resin composition having high transparency, which exhibits a high oxygen absorption, in particular a high initial oxygen absorption rate, without generating unpleasant odor by the oxygen absorption. Specifically disclosed is an oxygen-absorbing resin composition containing a thermoplastic resin (A) composed of a structural unit represented by the general formula (I) below, a transition metal salt (B), and additionally if necessary, a matrix resin (C). (In the formula, R1 and R2 are as defined in the description.)

La présente invention concerne une composition de résine absorbant l'oxygène ayant une transparence élevée, qui présente une absorption d'oxygène élevée, en particulier une vitesse initiale d'absorption d'oxygène élevée, sans générer d'odeur désagréable lors de l'absorption de l'oxygène. L'invention concerne spécifiquement une composition de résine absorbant l'oxygène contenant une résine thermoplastique (A) composée d'une unité structurale représentée par la formule générale (I) ci-dessous, un sel de métal de transition (B), ainsi que, si nécessaire, une résine de matrice (C). (Dans la formule, R1 et R2 sont tels que définis dans la description).
