Abstract
The invention relates to a composition for the oxidation dyeing of keratin fibres, and in particular human keratin fibres such as the hair, comprising, in a medium which is suitable for dyeing, at least one oxidation base, 1,3-bis(β-hydroxyethyl)amino-2-methylbenzene and/or at least one of the addition salts thereof with an acid as first coupler, and at least one substituted meta-aminophenol selected as second coupler, as well as to the dyeing process using this composition.
Claims32
1-32. (canceled)
A composition for the oxidation dyeing of keratin fibres comprising, in a medium which is suitable for dyeing:
- (a) at least one oxidation base,
- (b) and at least two couplers, wherein
- the first coupler is chosen from 1,3-bis(β-hydroxyethyl)amino-2-methylbenzene and an addition salt thereof with an acid, and
- the second coupler is chosen from 3-amino-2-chloro-6-methylphenol, 5-amino-4-chloro-2-methylphenol, and the addition salts thereof with an acid.
The composition according to claim 34, wherein the oxidation base is chosen from a para-phenylenediamine, a double base, a para-aminophenol, an ortho-aminophenol, and a heterocyclic oxidation base.
A process for dyeing keratin fibres comprising the steps of 1) applying to said fibres at least one dye composition, and 2) developing a color at acidic, neutral or alkaline pH using an oxidizing agent which is added to the dye composition at the time of use, or which is present in an oxidizing composition that is applied simultaneously with the dye composition or sequentially after application of the dye composition, said at least one dye composition comprising, in a medium which is suitable for dyeing:
- (a) at least one oxidation base,
- (b) and at least two couplers, wherein
- the first coupler is chosen from 1,3-bis(β-hydroxyethyl)amino-2-methylbenzene and an addition salt thereof with an acid, and
- the second coupler is chosen from 3-amino-2-chloro-6-methylphenol, 5 5-amino-4-chloro-2-methylphenol, and the addition salts thereof with an acid.
A multi-compartment dyeing kit comprising
- a first compartment that contains a dye composition for the oxidation dyeing of keratin fibers, and a second compartment that contains an oxidizing composition, said dye composition comprising, in a medium which is suitable for dyeing:
- (a) at least one oxidation base,
- (b) and at least two couplers, wherein
- the first coupler is chosen from 1,3-bis(β-hydroxyethyl)amino-2-methylbenzene and an addition salt thereof with an acid, and
- the second coupler is chosen from 3-amino-2-chloro-6-methylphenol, 5-amino-4-chloro-2-methylphenol, and the addition salts thereof with an acid.
