ABSTRACT:
The present invention relates to novel secondary para-phenylenediamines bearing an alkoxy group, to a process for preparing them, and to their use in the oxidation dyeing of hair. The invention also relates to a composition for dyeing keratin fibers, in particular human keratin fibers such as hair, containing, in a medium that is suitable for dyeing, at least one secondary para-phenylenediamine. Further, the invention relates to a process for dyeing keratin fibers using the aforementioned composition, and to a dyeing kit containing the composition.
