Oxidation dyeing composition containing at least one double associated to at least one simple and method of dyeing the implementing

摘要

The invention relates to dyeing compositions for keratinous fibres, containing: (a) at least one dye precursor belonging to the family (A) of single bases selected from paraphenylenediamines; b) at least one dye precursor of the family (B) of doubles bases selected from N,N'-diphenylalkylenediamines; the dye precursors of the families (A) and (B) being selected so that the intensity of the colouration on dyed bleached hair (VD) and the intensity on dyed and permanent-waved bleached hair VDP is such that VD-VDP = 0+/-0.5, the value being determined according to MUNSELL's notation; the mole ratio between the single bases of the family (A) and the double bases of the family (B) being between 3 and 10.
