摘要 |
The invention relates to the dyeing of keratin fibres using azomethine direct dyes or reduced precursors of azomethine direct dyes of formula (I) and (II) obtained from 2-amino-3-hydroxypyridine. The invention relates to a dye composition comprising at least one azomethine direct dye or a reduced precursor of an azomethine direct dye, to a process for dyeing keratin fibres, using the said composition, and to their uses in the dyeing of keratin fibres.
