  • the present invention relates to a composition for dyeing keratin fibres, in particular human keratin fibres such as the hair, comprising one or more fatty substances, one or more surfactants, one or more oxidation bases, one or more particular couplers of meta- aminopheno l type and one or more basifying agents, the fatty substance content in the dye composition representing in total at least 15 % by weight relative to the total weight of the said composition.
  • the invention also relates to a process for dyeing keratin fibres using the said composition in the presence of one or more chemical oxidizing agents, and also to a multi-compartment device suitable for using the said dye composition.
  • oxidation dye precursors which are generally known as oxidation bases, such as ortho- or para-phenylenediamines, ortho- or para-aminopheno ls or heterocyclic compounds such as pyrazoles, pyrazolinones or pyrazolopyridines .
  • oxidation bases are co lourless or weakly co loured compounds which, in combination with oxidizing products, can give rise to coloured compounds by an oxidative condensation process.
  • oxidation bases may be varied by combining them with couplers or coloration modifiers, the latter being chosen especially from aromatic meta- diamines, meta-aminophenols, meta-diphenols and certain heterocyclic compounds such as indo le or pyridine compounds .
  • couplers or coloration modifiers the latter being chosen especially from aromatic meta- diamines, meta-aminophenols, meta-diphenols and certain heterocyclic compounds such as indo le or pyridine compounds .
  • couplers or coloration modifiers the variety o f mo lecules used as oxidation bases and couplers allows a wide range o f co lours to be obtained.
  • the oxidation dyeing process thus consists in applying to keratin fibres a dye composition comprising oxidation bases or a mixture of oxidation bases and couplers with hydrogen peroxide (H 2 0 2 or aqueous hydrogen peroxide solution), as oxidizing agent, in leaving it to diffuse, and then in rinsing the fibres.
  • hydrogen peroxide H 2 0 2 or aqueous hydrogen peroxide solution
  • the use of these dye compositions may present a certain number o f drawbacks. Specifically, after application to keratin fibres, the dyeing power obtained may not be entirely satisfactory, or even poor, and lead to a restricted range of colours. The colorations may also not be sufficiently remanent with respect to external agents such as light, shampoo or perspiration, and may also be too selective, i.e. the co loration difference is too great along the same keratin fibre that is differently sensitized between its end and its root.
  • One of the obj ects of the present invention is especially to propose compositions for dyeing keratin fibres, in particular human keratin fibres such as the hair, which are especially capable of leading to a wide range of co lours with co lorations that are powerful, sparingly selective and remanent with respect to external agents (such as shampoo, light, perspiration or bad weather) .

  • the couplers used in the dye composition are chosen from the meta-aminophenols of formula (I).
  • the dye compositions make it possible to obtain colorations that are powerful, sparingly selective and remanent with respect to external agents (such as shampoo, light, perspiration or bad weather).
