Claim Text:
1. An oxygen-absorbing resin composition comprising a polyester compound having a constitutional unit (a), which has at least one tetralin ring, selected from the group consisting of the following general formulas (1) to (4): wherein each R independently represents 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, optionally further having a substituent; wherein at least one hydrogen atom is bound to a benzyl position of the tetralin ring; wherein X represents a divalent group comprising at least one group selected from the group consisting of an aromatic hydrocarbon group, a saturated or unsaturated alicyclic hydrocarbon group and a linear or branched and saturated or unsaturated aliphatic hydrocarbon group and a heterocyclic group; wherein each m independently represents an integer of 0 to 3 and each n independently represents an integer of 0 to 6 and a constitutional unit (b), comprising residue of tetrahydrophthalic anhydride derivative which is represented by the following general formula (5) and/or general formula (6), wherein each R independently represents 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, optionally further having a substituent; wherein each p independently-represents an integer of 1 to 5.
