Abstract:
1. An oxygen absorption resin composition comprising: a thermoplastic resin (A) having carbon-carbon double bonds substantially in its main chain, wherein the thermoplastic resin (A) is represented by a formula (III): wherein R a transition metal salt (B), and a gas barrier resin (C), wherein the thermoplastic resin (A) satisfies the following inequality (1): wherein a (mol/g) is an amount of carbon-carbon double bonds in its main chain, b (mol/g) is an amount of carbon-carbon double bonds in its side chain, and X is 10, wherein the oxygen absorption amount of the thermoplastic resin (A) is at least 1.6 moles per 1 mol of carbon·carbon double bonds of the thermoplastic resin (A), and wherein the gas barrier resin (C) is a polyvinyl alcohol resin having an oxygen transmission rate of 20 ml·20 μm(m
