Patent ID: 7141079

Claim:
A composition for the oxidation dyeing of keratinous fibers comprising, in a medium which is suitable for dyeing: a first coupler chosen from at least one 3,5-diaminopyridine derivative corresponding to the following general formula (I): wherein: R 1 and R 2 , which may be identical or different, are chosen from C 1 –C 4 alkyl radicals, C 1 –C 4 monohydroxyalkyl radicals, and C 2 –C 4 -polyhydroxyalkyl radicals, R 3 is chosen from hydrogen, C 1 –C 4 alkyl radicals, C 1 –C 4 monohydroxyalkyl radicals, C 2 –C 4 polyhydroxyalkyl radicals, and one of their addition salts with an acid; a second coupler chosen from at least one meta-phenylenediamine, and one of its addition salts with an acid, wherein the amount of the second coupler ranges from about 0.0001% to about 10% by weight relative to the total weight of the composition; and at least one oxidation base chosen from bases of the para-phenylenediamine type, and one of its addition salts with an acid.
