ABSTRACT:
The invention relates to a dye composition that is useful for dyeing keratin fibres, containing at least one oxidation base and at least one coupler of the 6-alkoxy-2,3-diaminopyridine type in which the amino radical in position 2 is a monosubstituted amino radical, to the use of this composition for dyeing keratin fibres and to the dyeing process using this composition. The invention also relates to novel 6-alkoxy-2,3-diaminopyridine compounds that are useful as couplers.
