Claim:
1. An oxygen-absorbing resin composition comprising a copolymerized compound and a transition metal catalyst, wherein the copolymerized compound comprises at least one constituent unit (a) selected from the group consisting of the constituent units represented by the following formulas (4) and (5): and, at least one constituent unit (b) having a tetralin ring, selected from the group consisting of the constituent units represented by the following formulas (2) and (3): where R 5 , R 6 and R 7 each independently represent a hydrogen atom or a second monovalent substituent, R 8 , R 9 , R 10 and R 11 each independently represent a third monovalent substituent, where the second monovalent substituent and the third monovalent substituent each independently represent 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 mercapto group, an alkylthio group, an arylthio group, a heterocyclic thio group and an imido group, these of which may further have a substituent; if a plurality of R 8 , R 9 , R 10 or R 11 are present, the plurality of R 8 , R 9 , R 10 and R 11 may be the same or different; m represents an integer of 0 to 3, n represents an integer of 0 to 7, p represents an integer of 0 to 6 and q represents an integer of 0 to 4; at least one hydrogen atom is bound to a benzyl position of the tetralin ring; X represents a bivalent group selected from the group consisting of —(C═O)O—, —(C═O)NH—, —O(C═O)—, —NH(C═O)—and —(CHR)s- where s represents an integer of 0 to 12; Y represents —(CHR)t- where t represents an integer of 0 to 12; and R represents a monovalent chemical species selected from the group consisting of a hydrogen atom, a methyl group and an ethyl group.
