摘要

The composition of staining of fibers queratu00ecnicas, the dyeing process of the fiber queratu00ecnicas, device with several compartments and use for dyeing fibers queratu00ecnicas oxidation of the present invention has for object to a composition of staining of fibres Co queratu00ednicas Mpreende 2,3 - diamine - 6.7 - diidro - 1H, 5h pirazalau00a21,2 it! Pyrazole - 1 - one for the first base oxidation.The parafenilenodiamina or parataluenodiamina for second base oxidation and a meta aminofenol replaced formula determined by the first acopladar, it being understood that the reason malar first coupler / first base oxidation is greater than 1, right malar first RA base oxidation / second base oxidation is between 0.5 and 1.5 and the quantity of the first base of malar oxidation is greater than or equal to 2,5.10u00ac - 3u00ac bad for 100 g of the composition. The present invention is also rejects the coloring process using such a composition. The present invention allows to obtain a staining of fibers queratu00ednica S with deep red tones, particularly visible, (Live) intense, aesthetics, very selective and tenacious.It also allows us to obtain a strong coloration at neutral pH.
