    摘要: The invention provides a bleaching catalyst and a bleaching composition having a sufficient bleaching effect even at low temperatures and being excellent in an effect of preventing color migration in fibers with less bleach of dyes and less damage to fibers. The invention provides a cyclic amide transition metal complex (1), a bleaching catalyst containing the same, and a bleaching composition containing the bleaching catalyst and a peroxy bleaching agent selected from hydrogen peroxide and a peroxide or an organic peracid generating hydrogen peroxide in an aqueous solution. wherein R1 to R6 represent H, a C1-16 hydrocarbon or perfluoroalkyl group or a halogen atom, R7 represents a C1-18 alkylene or perfluoroalkylene group, A represents a group having 1 to 3 quaternary ammonium groups substituted with an alkyl group or linked with an alkylene group, or a heterocyclic aromatic quaternary cation group, or the like, M represents a transition metal, L represents a ligand, and Q represents a counterion.
