Abstract

Abstract A composition and method for the oxidative coloring of hair are disclosed, on the basis of a developer substance-coupler substance combination, whereby as coupler substance at least one 3,5-diaminopyridine derivative of the general Formula ##STR1## in which R 1 and R 2 independent of each other are CH 3 , C 2 H 5 or C 2 H 4 OH and R 3 is hydrogen, C 1 -C 4 -alkyl or C 1 -C 4 -hydroxyalkyl, also in the form of the physiologically compatible salt, is used. The coupler substance, 3,5-diamino-2,6-dimethoxypyridine being preferred, should be present in the hair coloring composition in a concentration from 0.01 to 3.0% by weight, preferably 0.1 to 2.0% by weight. The coupler substances according to Formual I are storage-stable, well soluble in water, and have toxicologically as well as dermatologically favorable characteristics. The coupler substances according to Formula I produce in combination with 1,4-diaminobenzene or its derivatives very intensive blue-black tones without red portions, and in combination with 4-aminophenol, strongly lustrous gold-orange tones.
