Abstract
There are provided an oxygen absorbing resin composition, an oxygen absorbing multilayered body, and an oxygen absorbing hollow container that can absorb oxygen in an atmosphere even under a low-humidity atmosphere. The oxygen absorbing resin composition includes: (I) an oxygen absorbing agent consisting of a metal (a metal of (I)) obtained by subjecting an alloy comprising (A) at least one transition metal selected from the group consisting of manganese, iron, platinum, and copper group metals and (B) at least one metal selected from the group consisting of aluminum, zinc, tin, lead, magnesium, and silicon, to treatment with an acidic or alkaline aqueous solution to elute and remove at least a part of the component (B); and (II) a thermoplastic resin.
