    摘要: An object of the present invention is to provide: an oxygen-absorbing compound which has oxygen-absorbing properties and generates less odor, and an oxygen-absorbing adhesive composition and a coating agent composition each produced using the oxygen-absorbing compound. The oxygen-absorbing adhesive composition is used as an adhesive composition for forming an adhesive layer in a laminate for a packaging material, generates less odor, absorbs oxygen in a packaging bag or a packaging container to prevent the deterioration of a content in the packaging bag or the packaging container, and has an excellent balance among adhesion strength, the amount of generated odor and oxygen adsorption properties. The oxygen-absorbing coating agent composition is used as a coating agent composition for forming a coating layer for the surface of the laminate for a packaging material, generates less odor, absorbs oxygen penetrating through the laminate or oxygen in a packaging bag or a packaging container to prevent the deterioration of the coating layer or another constituent layer in the laminate or the deterioration of a content in the packaging bag or the packaging container due to the oxygen, and has an excellent balance among blocking resistance, the amount of generated odor and oxygen absorbing properties. The oxygen-absorbing compound has one or two or more unsaturated five-membered rings, wherein any bond between five carbon atoms constituting the unsaturated five-membered ring is a carbon-carbon double bond, when there is one unsaturated five-membered ring, the five-membered ring or the organic group 1 has a functional group having active hydrogen or a group in which active hydrogen of the functional group having active hydrogen is replaced with a monovalent organic group 2, and when there are two or more unsaturated five-membered rings, the unsaturated five-membered rings are bonded to each other via a divalent or higher organic group 2 that replaces active hydrogen of an active hydrogen group on each of the five-membered rings or the organic group 1.
