Abstract

The present invention relates to a composition which is used for oxidizing the dyeing keratin fiber, especially the human keratin fiber such as curled hair, and the composition includes 4,5-diamino-1-( beta -hydroxyethyl) or ( beta -methoxyethyl)-1H-pyrazole as the oxidation base and 6- hydroxyindole as color coupler. The invention also relates to the application of the oxidizing dyeing composition for the dyeing keratin fiber, and a method for dyeing with the composition.

Description

technical field [0001] The present invention relates to compositions for the oxidative dyeing of keratin fibers, especially human keratin fibers, such as hair, comprising 4,5-diamino 1-(β-hydroxyethyl)-1H-pyrazole or 4,5- Diamino-1-(β-methoxyethyl)-1H-pyrazole as oxidation base and 6-oxindole as coupler. Background technique [0002] Dyeing compositions known for dyeing keratin fibers in general, especially for human keratin fibers such as hair, comprise oxidation dye precursors, commonly known as oxidation bases, such as o- or p-phenylenediamine, ortho- or p-aminophenol and heterocyclic compounds. These oxidation bases are colorless or weakly colored compounds which, when combined with oxidation products, give colored compounds through oxidative condensation processes. [0003] It is also known that the shades obtained with these oxidation bases can be varied by combining them with couplers or color modifiers, these agents can be selected from aromatic m-diamines, m-amino...
