The invention relates to the dyeing of keratin fibres using azomethine direct dyes or precursors of azomethine dyes obtained from 2-alkylresorcinols. The invention relates to a dye composition comprising at least one azomethine direct dye or pre-cursor 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. This composition allows a particularly stable and fast coloration to be obtained.
