A process for dyeing keratin fibres is disclosed which involved applying: (a) at least one dyestuff of the formula: ##STR1## in which R.sub.1 and R.sub.2 independently designate hydrogen, amino, alkylamino, --NH--aliphatic--(X).sub.m, dialkylamino or --N--(aliphatic-(X).sub.m).sub.2, R.sub.3 designates hydrogen, OH, alkoxy or --O--aliphatic-(X).sub.m "aliphatic" designates an aliphatic radical having 2 to 4 free valencies, m designates an integer from 1 to 3 such that if m=1 X represents OH, Cl, OCH.sub.3 or OCH.sub.2 CH.sub.2 OH, or, if m designates 2 or 3, X designates OH, and R.sub.4 designates hydrogen, alkyl or halogen, with the proviso that at least one of R.sub.1, R.sub.2 and R.sub.3 is other than hydrogen, and that, if R.sub.1 and R.sub.2 are both other than hydrogen, R.sub.3 designates hydrogen, (b) at least one dyestuff of the formula: ##STR2## in which R.sub.5 designates hydrogen, amino, aminoalkyl, NH-aliphatic-(X).sub.m, N-(alkyl).sub.2, N-(aliphatic(X).sub.m).sub.2, or NHCH.sub.2 CH.sub.2 NH.sub.2, R.sub.6 designates hydrogen, OH, alkoxy, O-aliphatic(X).sub.m or O(CH.sub.2).sub.n NH.sub.2, R.sub.7 designates hydrogen, alkyl or halogen, A designates-Y-(CH.sub.2)--.sub.n, --OCH.sub.2 CHOH--CH.sub.2 -- or ##STR3## where R.sub.8 designates hydrogen or methyl, Y designates oxygen or --NH-- and n is an integer from 2 to 4, and m "aliphatic" and X are as defined above, with the proviso that, if Y designates --NH-- and R.sub.6 is other than hydrogen, R.sub.5 designates hydrogen, and, if Y is an oxygen atom, R.sub.6 designates hydrogen, the shade and chromaticity of the color obtained with the dyestuff(s) of formula (I) and the shade and chromaticity of the color obtained with the dyestuff(s) of formula (II) being such that .DELTA.H+.DELTA.C is less than or equal to 4.5
揭示了一种染色角蛋白纤维的方法,其中涉及应用:(a)至少一种公式为:##STR1## 其中R.sub.1和R.sub.2分别代表氢,氨基,烷基氨基,--NH--脂肪基--(X).sub.m,二烷基氨基或--N--(脂肪基-(X).sub.m).sub.2,R.sub.3代表氢,OH,烷氧基或--O--脂肪基-(X).sub.m,“脂肪基”代表具有2至4个自由价的脂肪基,m代表整数1至3,使得如果m=1,X代表OH,Cl,OCH.sub.3或OCH.sub.2 CH.sub.2 OH,或如果m代表2或3,X代表OH,R.sub.4代表氢,烷基或卤素,但前提是R.sub.1,R.sub.2和R.sub.3中至少有一个不是氢,且如果R.sub.1和R.sub.2都不是氢,则R.sub.3代表氢,(b)至少一种公式为:##STR2## 其中R.sub.5代表氢,氨基,氨基烷基,NH-脂肪基-(X).sub.m,N-(烷基).sub.2,N-(脂肪基(X).sub.m).sub.2或NHCH.sub.2 CH.sub.2 NH.sub.2,R.sub.6代表氢,OH,烷氧基,O-脂肪基(X).sub.m或O(CH.sub.2).sub.n NH.sub.2,R.sub.7代表氢,烷基或卤素,A代表-Y-(CH.sub.2)--.sub.n,--OCH.sub.2 CHOH--CH.sub.2--或##STR3## 其中R.sub.8代表氢或甲基,Y代表氧或--NH--,n为2至4的整数,m“脂肪基”和X如上所定义,但前提是,如果Y代表--NH--且R.sub.6不是氢,则R.sub.5代表氢,如果Y是一个氧原子,则R.sub.6代表氢,使用公式(I)和公式(II)的染料的色调和色度以满足.DELTA.H + .DELTA.C小于或等于4.5。
