摘要

(57) Abstract As for this invention, for dyeing in suitable medium: As - cup Ra, at least chiazoroazoru S-okishido of 1 kinds and/or at least the chemical compound of 1 kinds of formula: In formula: As for R₁ especially hydrogen, halogen, aryl oxy, alkoxy and acyloxy, aryl thio, alkyl thio, acetamide; R the NR ^{IIIR IV} basis and the like which had ^{III which} displays C₁ -C4 alkyls and R ^IV displaying; Mutually independence, as for Z _a, Z _b and Z _c, if it is not the nitrogen atom, R₂, R₃ or displaying the carbon atom which had the R₄ basis; It is offered as follows: When the carbon atom where - Z _a had the R₂ basis it defines, Z _b displays the nitrogen atom, Z _c is defined the carbon atom which had the R₃ basis; When - Z _a nitrogen atom it defines, Z _b displays the carbon atom which had the R₄ basis, Z _c is defined nitrogen atom: R₂, R₃ and R₄ especially hydrogen; Direct or ramification C₁ -C4 alkyls which are done; The aryl and the like which is substituted optionally displaying; n has the value of 1 or 2; - The oxidation base of 1 kinds is had at least, the keratin fiber, it regards the composition for oxidation dyeing of keratin fiber of person like the especially hair. In addition that regards also using that kind of composition for dyeing process.
