Claims

1. The use of aminophenol derivatives of General formula I

in which one of the two residues R ¹ and R ² means a hydrogen atom, and the other residue means a hydrogen atom, chlorine or fluorine and one of the two residues R ³ and R ⁴ means a hydrogen atom, an alkoxy group with from one to four carbon atoms, an alkyl group with one to four carbon atoms, a hydroxyalkyl group with one to four carbon atoms, preferably with a terminal hydroxyl group, or a halogen atom, and the other residue represents one of the groups —O — CH ₂ —CH═CH ₂ , -CH = CH-SOOH, with X being a hydrogen atom or a physiologically harmless inorganic or organic cation, and if it is a radical R ^3, then a group

and for the case of R ⁴ , it means

and in these formulas -A- in each case means one of the groups - (CH ₂ ) _x -, where x means a number from one to four, -O- (CH ₂ ) _y -O-, where y means a number from one to four, -O- (C _n H _2n-z (OH) _z ) -O-, where n is a number from one to ten and z is one or if n is greater than or equal to three, then z is two, -O- ( C ₂ H ₄ -O) _u -, where u means a number from one to four and -O- (C ₃ H ₆ -O) _v -, where v means a number from one to four, and their water-soluble salts as manifesting components in the means for oxidative dyeing hair.

2. Means for oxidative dyeing of keratin fibers, containing paint-forming components and developing components in a water-based carrier, characterized in that it contains an aminophenol derivative of general formula I or its water-soluble salt as a developing component.

3. Means for oxidative dyeing under item 2, characterized in that both the residue R ¹ and R ² in the General formula I mean a hydrogen atom.

4. Means for oxidative dyeing under item 2 or 3, characterized in that the residues R ³ or R ⁴ in the General formula I mean a hydrogen atom.

5. Tool for oxidative dyeing in one of the paragraphs. 2 to 4, characterized in that X in the general formula I means a hydrogen atom.

6. Tool for oxidative dyeing in one of the paragraphs. 2-5, characterized in that in the general formula I n means numbers from one to six, first of all from one to three, and z is equal to one.

7. Means for oxidative dyeing in one of the paragraphs. 2 to 6, characterized in that it, along with aminophenol derivatives, contains at least one other manifesting component.

8. Means for oxidative dyeing under item 7, characterized in that the additional developing component is selected from 2,4,5,6-tetraaminopyrimidine, 4-hydroxy-2,5,6-triaminopyrimidine, 1- (β-hydroxyethyl) - 2,5-diaminobenzene, p-phenylenediamine, p-toluylenediamine, p-aminophenol, 3-methyl-p-aminophenol and 2-aminomethyl-p-aminophenol.

9. Tool for oxidative dyeing in one of the paragraphs. 2 to 8, characterized in that the developing components are contained in it in an amount of 0.005 to 20 wt.%, Preferably 0.1 to 5 wt.%, And paint-forming components in amounts of 0.005 to 20 wt.%, Preferably 0.1 to 5 wt.%, in each case based on the entire mass of the means for oxidative dyeing.

10. Tool for oxidative dyeing in one of the paragraphs. 2 to 9, characterized in that it also includes at least one direct dye.
