The invention relates to a composition dye for keratin fibers, in particular for human keratin fibers such as hair, comprising, in a medium suitable for the dye, at least one dye precursor para type oxidation chosen from the group consisting of 3-methyl para-aminophenol, 2-methyl para-aminophenol, 2-hydroxymethyl para-aminophenol and their addition salts with an acid; at least one coupler chosen from the group consisting of 2-methyl 5-aminophenols of formula (I): in which R denotes a hydrogen atom, a methyl or ethyl radical, or a group .beta.-hydroxyethyl or .gamma.-hydroxypropyl, and their salts addition with an acid; and at least one precursor of additional oxidation dye chosen from ortho-aminophenol, 3-acetylamino 6-aminophenol and their addition salts with an acid. The use of a such composition when applied to hair in the presence of an oxidizing agent, in an acid medium or alkaline, allows to obtain colorings with warm and coppery nuances with good resistance to light, washing, bad weather, to sweating and to the different treatments that can undergo hair. |
