Process for dyeing keratinous fibers with 2,4-diamino-1,3-dimethoxybenzene at an acid ph and compositions employed

Process for dyeing keratinous fibres, especially human keratinous fibres such as the hair, characterised in that a composition containing, in a medium suitable for dyeing, at least 2,4-diamino-1,3-dimethoxybenzene as a coupler; an oxidation dye precursor; and an oxidising agent; is applied to these fibres, the pH of the composition applied to the fibres being less than 7.

Metaphenylenediamines in dyeing compositions for keratinic fibers

Dye compositions comprising a coupler having to the formula STR1 in which formula R1 and R2 are identical or different and represent a hydrogen atom or an alkyl radical having 1 to 2 carbon atoms and n represents a number equal to 1 or 2 and a paraphenylenediamine. This coupler is particularly suitable for use in a dyeing composition comprising paraphenylenediamines responding to the formula STR2 or the corresponding acid salts; formula in which R1, R2 and R3 are identical or different and represent a hydrogen atom, an alkyl or alkoxy radical having 1 to 2 carbon atoms, R4 and R5 are identical or different and represent a hydrogen atom, a alkyl radical, hydroxyalkyl, alkoxyalkyl in which the alkoxy group comprises 1 to 2 carbon atoms, carbamylalkyl, mesylaminoalkyl, acetylaminoalkyl, ureidoaminoalkyl, carbethoxyaminoalkyl, the alkyl groups in R4 and R5 having 1 to 3 carbon atoms, with the reservation that R1 or R3 represents hydrogen when R4 and R5 do not represent a hydrogen atom.
