Abstract
An aqueous hair dye preparation comprising an oxidation dyestuff combination of a developer component and a coupler component consisting of an N,N-bis-(.beta.-hydroxyethyl)-m-phenylenediamine as well as a process for dyeing hair by utilizing this oxidation dyestuff combination.
Claims16
An oxidation hair coloring composition consisting essentially of, as coupling agent at least one compound selected from the group of N,N-bis-(.beta.-hydroxyethyl)-m-phenylenediamines having the formula I ##STR2## wherein R represents hydrogen or an alkoxy group, the alkyl portion of which contains one to four carbon atoms, and the water-soluble hair compatible organic or inorganic salts thereof;
- and a water-soluble developer therefor, said developer and said coupling agent being present in the molar range of 2:1 to 1:2.
An oxidation hair coloring composition consisting essentially of, as coupling agent at least one compound selected from the group of N,N-bis-(.beta.-hydroxyethyl)-m-phenylenediamines having the formula I ##STR3## wherein R represents hydrogen or an alkoxy group, the alkyl portion of which contains one to four carbon atoms, and the water-soluble hair compatible organic or inorganic salts thereof;
- and a water-soluble, nitrogen-based developer therefor selected from the group consisting of a p-phenylenediamine derivatives, diaminopyridines, 4-aminopyrazolone derivatives, heterocyclic hydrazone derivatives, and tetraaminopyrimidines, said developer and said coupling agent being present in the molar range of 2:1 to 1:2.
