Abstract:
The subject of the invention is a composition for the oxidation dyeing of keratinous fibers containing at least one N-substituted 4-hydroxyindoline derivative as coupler and at least one oxidation base. The invention also relates to new N-substituted 4-hydroxyindoline derivatives, to their process of synthesis, to their use as couplers for the oxidation dyeing of keratinous fibers, in combination with at least one oxidation base, and to the dyeing processes in which they are used.
