Claim:
1. An oxygen absorbent composition comprising a compound (A) having two or more tetralin rings, at least one of the tetralin rings having a hydrogen atom bonded to a benzylic position thereof, and having two or more imide bonds, and a transition metal catalyst, wherein the compound (A) is at least one compound selected from a group consisting of the following general formulas (1) to (4): wherein R each independently represents a hydrogen atom or a monovalent substituent, the monovalent substituent is at least one selected from a 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 amide 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 imide group, and R may further have a substituent; m represents an integer of 0 to 6, n represents an integer of 0 to 3, p represents an integer of 0 to 7, q represents an integer of 0 to 2, r represents an integer of 0 to 4, s represents an integer of 0 to 5, and in at least one tetralin ring, one or more hydrogen atoms are bonded to a benzylic position thereof; and X represents a divalent substituent, and the divalent substituent is at least one selected from a group consisting of an aromatic hydrocarbon group, a saturated or unsaturated alicyclic hydrocarbon group, a linear or branched, saturated or unsaturated aliphatic hydrocarbon group, and a heterocyclic group.
