A two-component curable oxygen-absorbing composition comprises a polyester comprising structural units derived from an acid component (A) and an acid component (B), wherein the ratio of the acid component (A) to total acid components is 70 mol % to 95 mol %, the ratio of the acid component (B) to total acid components is 0 mol % to 15 mol %, the polyester has a glass transition temperature of &#x2212;20&#xb0; C. to 0&#xb0; C., the resin is cured using a diisocyanate hardening agent, and the acid component (A) is a tetrahydrophthalic acid or a derivative thereof, or a tetrahydrophthalic acid anhydride or a derivative thereof, and the acid component (B) is a phthalic acid or an analog thereof.

Resin for oxygen-absorbing adhesive and oxygen-absorbing adhesive

The purpose of the present invention is to provide a two-part curable oxygen-absorbable resin composition which has all of oxygen absorbability, adhesion properties and a cohesive force. The present invention provides a two-part curable oxygen-absorbable resin composition comprising: a main component which comprises a polyester polyol containing tetrahydrophthalic acid or a derivative thereof or tetrahydrophthalic acid anhydride or a derivative thereof as a raw material; and an aliphatic and/or alicyclic isocyanate curing agent component.
