Patent ID: 7396865

Claim:
An oxygen absorber comprising a solid mixture comprising at least one N-hydroxyimide compound represented by Formula (1); and at least one oxidizable polymer, wherein R 1 and R 2 each independently indicates a hydrogen atom, a halogen atom, an acyl group, an alkyl group, an aryl group, an aralkyl group, a heteroaryl group, a hydroxyl group, a hydroxyl group protected by a protecting group, a mercapto group protected by a protecting group, a carboxyl group, metal salt of a carboxyl group, a carboxyl group protected by a protecting group, an aldehyde group protected by a protecting group, an amino group protected by a protecting group, a dialkylamino group, an amide group, a sulfonic group, metal salt of a sulfonic group, a sulfonic ester group, a group expressed by a formula of —OP(═O)(OH) 2 , metal salt or an ester derivative of a group expressed by a formula of —OP(═O)(OH) 2 , a group expressed by a formula of —P(═O)(OH) 2 , or metal salt or an ester derivative of a group expressed by a formula of —P(═O)(OH) 2 , R 1 and R 2 may form a ring together with carbon atoms to which they are bonded, and R 1 and/or R 2 may form a carbon-carbon double bond with carbon atoms to which they are bonded.
