ABSTRACT:
The invention relates to 2,4-diamino-1,3,5-trimethoxybenzene, a process for its preparation by catalytic reduction of 2,4-dinitro-1,3,5-trimethoxybenzene, and to its use, as a coupler, in combination with at least one oxidation dye precursor of the para type, for dyeing keratinous fibres and particularly human hair.
The hair dyeing compositions according to the invention contain, in a cosmetically acceptable aqueous substrate, 0.05 to 3.5% by weight of 2,4-diamino-1,3,5-trimethoxybenzene or one of its salts, which imparts strong blue colors to hair when it is combined with p-phenylenediamines, or red colors when it is combined with p-aminophenols, in an alkaline oxidizing medium.
