BLEACHING ACTIVATOR HAVING DENDRIMER LIGAND AND ITS METAL COMPLEX

摘要

PROBLEM TO BE SOLVED: To provide a new bleaching activator having dendrimer ligand and its metal complex. SOLUTION: The dendrimer ligand comprises a compound represented by the formula (R1R1)N-X-N(R1R1) [wherein R1 is a group represented by the formula: (R2R3)N-(CH2)n-; R2 and R3 are each a group represented by the formula: (R4R5)N-(CH2)n-; n is 2 or 3; or R2 and R3 may be combined together to form a group represented by formula A; or R2 is H, and R3 is a group represented by formula (2); R4 and R5 are each a group represented by the formula: (R6R7) N-(CH2)n-; n is 2 or 3; or R4 and R5 may be combined together to form a group represented by formula A; or R4 is H, and R5 is a group represented by formula (3)]. The metal complex comprises a complex of the compound with a transition metal.
