Abstract
The invention relates to a composition comprising at least one oxidation coupler chosen from 6-hydroxybenzomorpholine of formula (I), one of its addition salts, its solvates and/or the solvates of its salts, and mixtures thereof, at least one oxidation base, at least one compound chosen from etidronic acid, its salts, and mixtures thereof and at least one compound chosen from 2,6-dipicolinic acid, its salts, and mixtures thereof. The invention also relates to a process for dyeing keratin fibres, preferably the hair, comprising the application of the composition to said keratin fibres.

1-16. (canceled)
A composition comprising:
- at least one oxidation coupler chosen from 6-hydroxybenzomorpholine of formula (I), addition salts thereof, solvates thereof, solvates of salts thereof, or mixtures of two or more thereof:
- at least one oxidation base;
- at least one compound chosen from etidronic acid, salts thereof, or mixtures of two or more thereof, and
- at least one compound chosen from 2,6-dipicolinic acid, salts thereof, or mixtures of two or more thereof.
A method for dyeing keratin fibers, comprising:
- (i) mixing at least a dyeing composition with an oxidizing composition,
- wherein the dyeing composition comprises:
- at least one oxidation coupler chosen from 6-hydroxybenzomorpholine of formula (I), addition salts thereof, solvates thereof, solvates of salts thereof, or mixtures of two or more thereof:
- at least one oxidation base, and
- optionally at least one alkaline agent;
- wherein the oxidizing composition comprises at least one chemical oxidizing agent,
- wherein at least one of the dyeing composition or the oxidizing composition comprises a) at least one compound chosen from etidronic acid, salts thereof, or mixtures of two or more thereof, or b) at least one compound chosen from 2,6-dipicolinic acid, salts thereof, or mixtures of two or more thereof, and optionally at least one fatty substance;
- and
- (ii) applying the mixture to the keratin fibers.
A multi-compartment device for dyeing keratin fibers comprising:
- at least one first compartment comprising a dyeing composition comprising:
- at least one oxidation coupler chosen from 6-hydroxybenzomorpholine of formula (I), one of addition salts thereof, solvates thereof, solvates of salts thereof, or mixtures of two or more thereof:
- at least one oxidation base, and
- optionally at least one alkaline agent;
- and
- at least one second compartment comprising an oxidizing composition comprising at least one chemical oxidizing agent, and
- wherein at least one of the dyeing composition or the oxidizing composition comprises a) at least one compound chosen from etidronic acid, salts thereof, or mixtures of two or more thereof, or b) at least one compound chosen from 2,6-dipicolinic acid, salts thereof, or mixtures of two or more thereof, and optionally at least one fatty substance.
