The invention relates to the dyeing of keratin fibres using azomethine direct dyes or reduced precursors of azomethine direct dyes obtained from secondary, N-alkylaminated para-phenylenediamines. The subject of the present application is direct dyes derived from 2-[2-[(4-aminophenyl) amino] ethyl}(2-hydroxyethyl) amino]ethanol, a dye composition comprising the direct dyes, a method for dyeing keratin fibres using the direct dyes and the use of these dyes for dyeing keratin fibres. This composition makes it possible to obtain a particularly stable and persistent colouring.
