NEW TYPE OXIDATION BASE INCLUDING GUANIDINE CHAIN, ITS PRODUCTION PROCESS, APPLICATION OF OXIDATION DYEING OF KERATIN FIBER USING THE SAME, COMPOSITION FOR OXIDATION DYEING AND DYEING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a compound that is suitable to use as the oxidation base and gives the strong color tone in the wide range color and also to provide a compound that has a good durability to various treatments of keratin fiber.;SOLUTION: A compound of formula (I) is used as an oxidation base. [In the above formula, X1 and X2 show hydroxy, -NHR1 or -NR1R2 group. R1 and R2 show each hydrogen a 1-8C alkyl group or the like. When X1 and/or X2 show -NRNR2, R1 and R2 can form a 4, 5 or 6-membered ring cooperated with bonded nitrogen, and R1 and R2 may show a 4, 5 or 6-membered ring of aromatics or non-aromatics, the ring can include hetero-atom, A shows -CH=N- or-CH2-NH-. Z shows hydrogen, a halogen, 4, 5 or 6-membered ring of aromatics or non-aromatics].;COPYRIGHT: (C)2001,JPO
