An active oxygen inhibitor composition containing a coordinated complex represented by general formula (I) as the active ingredient (wherein R1 and R2 represent each independently hydrogen, C1-C12 alkyl, C1-C12 alkoxy, halogen, hydroxy, nitro, amino, carboxy or C2-C6 acyloxy; and M represents a central atom selected from among Cu, Mn and Zn); and a coordinated complex represented by general formula (II), wherein R1-a and R2-a are the same as the R1 and R2 defined in formula (I); and Ma represents either Cu or Mn, provided that the case where Ma represents Cu and each of R1-a and R2-a represents hydrogen, the case where R1-a represents hydrogen and R2-a represents hydroxy located either at the 4-position or at the 5-position, and the case where Ma represents Mn and each of R1-a and R 2-a represents hydrogen are excepted. <CHEM> |
