Abstract (en)

[origin: WO2008043967A2] The present invention relates to a process for dyeing keratin fibres, in particular human keratin fibres such as the hair, using a dye composition comprising at least one dye of styryl or imine type in the presence of a revealing composition comprising at least one optionally substituted (hetero)aromatic compound of weak acid type. It also relates to a device suitable for implementing said process. The present invention makes it possible in particular to obtain a chromatic and fast coloration of keratin fibres, which is visible even on dark hair without prior lightening. It also makes it possible to obtain a coloration which, under certain conditions, does not stain.
