ABSTRACT:
A composition for use in the dyeing of keratinous fibres, particularly human hair, in order to produce a true dark black color, comprises an aqueous, substantially oxygen-free solution of the dye-precursors 2-methoxy-p-phenylenediamine and 2,4-diaminophenol, the composition having a pH value of from 6 to 12. The molar concentration of one dye precursor to the other is preferably from 1:10 to 10:1, and together they form from 0.25 to 15% by weight of the composition. Optionally, the composition can also contain a detergent and/or a thickening agent.
