PURPOSE:To enhance deodorizing capacity, by containing a Diels-Alder type addition reaction product of alpha,beta-unsaturated dicarboxylic anhydride and olefins or a derivative thereof as a deodorizing component. CONSTITUTION:Deodorizing urethane foam is constituted by containing a deodorizing component in an urethane foam base material. The deodorizing component contains a Diels-Alder reaction type addition reaction product of alpha,beta-unsaturated dicarboxylic anhydride and olefins or a derivative thereof. As other deodorizing component, a copper compound can be further contained. |
