摘要：
Composition for immediate use for oxidation dyeing of keratinic fibres, preferably human hair, comprises in a suitable medium: (i) at least one oxidation base (ii) at least one 3-aminophenol type coupler of formula (I) or their addition salts with an acid (iii) at least one direct cationic dye of formula (II) and (iv) at least one oxidising agent. R1 = H, 1-4 C alkyl, 1-4 C monohydroxyalkyl or 2-4 C polyhydroxyalkyl R2 = H, 1-4 C alkyl, 1-4 C alkoxy or Cl, Br or F R3 = 1-4 C alkyl, 1-4 C alkoxy, 1-4 C monohydroxyalkyl, 2-4 C polyhydroxyalkyl, 1-4 C monohydroxyalkoxy or 2-4 C polyhydroxyalkoxy D = N or CHR4 R4, R5 = H, 1-4 C alkyl (optionally substituted by CN, OH or HN2) or R4 or R5 together with a C atom of the benzene ring may form a heterocycle (optionally containing N or O and which is optionally substituted by one or more 1-4 C alkyl groups) or 4-aminophenyl R6 = H, Cl, Br, I, F, 1-4C alkoxy or 1-4C acetyloxy X<-> = chloride, methyl sulphate or acetate A = N-containing heterocycle substituted by at least one R7 and optionally by R8 R7 = 1-4 C alkyl (optionally substituted by OH) and R8 = 1-4 C alkoxy provided that when D = CH, then A = 1-(R7)-2- or 4-pyridinium and if R6 is other than alkoxy than R4 and R5 are not both H.Linvention a pour objet une composition prête à lemploi pour la teinture doxydation des fibres kératiniques, en particulier des fibres kératiniques humaines telles que les cheveux, comprenant au moins une base doxydation en association avec au moins un coupleur de type méta-aminophénol substitué, au moins un colorant direct cationique et au moins un agent oxydant, ainsi que le procédé de teinture mettant en oeuvre cette composition.
