1. An oxygen-absorbing resin composition comprising a polyester compound and a transition metal catalyst,
wherein the polyester compound has at least one constituent unit having a tetralin ring selected from the group consisting of constituent units represented by the following general formulas (1) to (4): where R each independently represent a monovalent substituent, the monovalent substituent being at least one selected from the group consisting of a halogen atom, an alkyl group, an alkenyl group, an alkynyl group, an aryl group, a heterocyclic group, a cyano group, a hydroxy group, a carboxyl group, an ester group, an amido group, a nitro group, an alkoxy group, an aryloxy group, an acyl group, an amino group, a thiol group, an alkylthio group, an arylthio group, a heterocyclic thio group and an imido group, these of which may further have a substituent; where m each independently represent an integer of 0 to 3; where n each independently represent an integer of 0 to 6, and at least one hydrogen atom is bound to a benzyl position of the tetralin ring; where X each independently represent a divalent group containing at least one group selected from the group consisting of an aromatic hydrocarbon group, a saturated or unsaturated alicyclic hydrocarbon group, a linear or branched and saturated or unsaturated aliphatic hydrocarbon group and a heterocyclic group; and wherein the polyester compound is a polyester compound having a tetralin ring obtained by synthesis using a zinc compound. |
