摘要:
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.

摘要:
New-meta-phenylenediamines are described for use in dyeing keratin fibres, especially human hair. These have the general formula: ##STR1## in which R represents an alkyl radical containing from 1 to 4 carbon atoms and n is an integer of from 1 to 3, or an acid salt thereof from 1 to 3 and include their acid salts.
