Oxidation dye composition for keratinous fibres comprising a para-aminophenol, 2-methyl-5-aminophenol and a para-phenylenediamine and/or a bis(phenylalkylenediamine)

A composition for dyeing keratinous fibers comprising in a medium suitable for dyeing said fibers,

• (a) an amount effective to dye said fibers of at least one oxidation dye precursor selected from the group consisting of 3-methyl-para-aminophenol, 2-methyl-para-aminophenol, 2-hydroxymethyl-para-aminophenol and an acid addition salt thereof;
• (b) an amount effective to dye said fibers of at least one coupling agent comprising 2-methyl-5-aminophenol or an acid addition salt thereof;
• and
• (c) an amount effective to dye said fibers of at least one oxidation dye precursor selected from the group consisting of
• (i) a paraphenylenediamine having the formula ##STR5## wherein R.sub.1, R.sub.2 and R.sub.3, each independently, represent hydrogen, halogen, alkyl, alkoxy, a carboxyl radical, a sulpho radical or C.sub.1 -C.sub.4 hydroxyalkyl,
• R.sub.4 and R.sub.5, each independently, represent hydrogen, alkyl, hydroxyalkyl, alkoxyalkyl, carbamylalkyl, mesylaminoalkyl, acetylaminoalkyl, ureidoalkyl, carbalkoxyaminoalkyl, sulphoalkyl, piperidinoalkyl, morpholinoalkyl or phenyl optionally para-substituted with an amino group,
• or R.sub.4 and R.sub.5 together with the nitrogen atom to which R.sub.4 and R.sub.5 are attached form a piperidino or morpholino heterocycle;
• with the proviso that R.sub.1 or R.sub.3 represent hydrogen when R.sub.4 and R.sub.5 do not represent hydrogen and
• with the proviso that when R.sub.1, R.sub.2 and R.sub.3 represent hydrogen, one of R.sub.4 and R.sub.5 is other than hydrogen, and
• when R.sub.4 and R.sub.5 represent hydrogen, one of R.sub.1, R.sub.2 and R.sub.3 represents methyl and at least one of the other two represents other than hydrogen;
• and
• (ii) a bis(phenylalkylenediamine) of formula (II) ##STR6## wherein Z.sub.1 and Z.sub.2, each independently, represent hydroxyl or NHR.sub.9 wherein R.sub.9 represents hydrogen or lower alkyl;
• R.sub.7 and R.sub.8, each independently, represent hydrogen, halogen or alkyl;
• R.sub.6 represents hydrogen, alkyl, hydroxyalkyl or aminoalkyl wherein the amino moiety is optionally substituted;
• Y represents a member selected from the group consisting of --(CH.sub.2).sub.n --, --(CH.sub.2).sub.m --O--(CH.sub.2).sub.m --, --(CH.sub.2).sub.m --CHOH--(CH.sub.2).sub.m -- and ##STR7## wherein n is an integer ranging from 0 to 8 and m is an integer ranging from 0 to 4;
• or
• an acid addition salt of (i) or (ii).
