ABSTRACT:

The invention relates to novel monobenzenic couplers comprising at least one cationic group Z, Z being chosen from aliphatic chains comprising at least one quaternized unsaturated ring, to the use thereof for the oxidation dyeing of keratin fibres, to dye compositions containing them, and to oxidation dyeing processes using them.
It is known practice to dye keratin fibres, and in particular human hair, with dye compositions containing oxidation dye precursors, in particular ortho-phenylenediamines or para-phenylenediamines, ortho-aminophenols or para-aminophenols and heterocyclic compounds such as diaminopyrazole derivatives, which are generally referred to as oxidation bases. The oxidation dye precursors, or oxidation bases, are colourless or weakly coloured compounds which, when combined with oxidizing products, can give rise to coloured compounds and dyes by a process of oxidative condensation.
It is also known that the shades obtained with these oxidation bases can be varied by combining them with couplers or coloration modifiers, the latter being chosen in particular from aromatic meta-diamines, meta-aminophenols, meta-diphenols and certain heterocyclic compounds.
The variety of molecules used as oxidation bases and couplers makes it possible to obtain a wide range of colours.
The so-called “permanent” coloration obtained by means of these oxidation dyes must moreover satisfy a certain number of requirements. Thus, it must have no toxicological drawbacks and it must allow shades of the desired strength to be obtained and have good resistance to external agents (light, bad weather, washing, permanent-waving, perspiration and friction).
The dyes must also allow white hairs to be covered, and, lastly, they must be as unselective as possible, i.e. they must allow the smallest possible differences in coloration to be produced over the entire length of the same keratin fibre, which may indeed be differently sensitized (i.e. damaged) between its tip and its root.
It has already been proposed, in particular in patent application FR-A-2 520 358,to use certain cationic derivatives of meta-phenylenediamines, i.e. more specifically, certain meta-phenylenediamines monosubstituted with a quaternized aliphatic chain, for the oxidation dyeing of keratin fibres in intense shades. However, the use of the meta-phenylenediamines described in that prior patent application does not make it possible to obtain a wide variety of colours and, furthermore, the colorations obtained are not always entirely satisfactory as regards their resistance with respect to the various attacking factors to which the hair may be subjected (the action of light, perspiration, shampooing, etc.).
The Applicant has now discovered, entirely surprisingly and unexpectedly, that certain novel monobenzenic compounds of formula (I) defined below comprising at least one cationic group Z, Z being chosen from aliphatic chains comprising at least one quaternized unsaturated ring, are not only suitable for use as couplers for oxidation dyeing, but also make it possible to obtain dye compositions which give intense colorations, in a very wide range of shades, and which have excellent properties of resistance to the various treatments to which the keratin fibres may be subjected. Finally, these compounds are found to be easy to synthesize.
These discoveries form the basis of the present invention.
A first subject of the invention is thus novel compositions of formula (I) below, and the addition salts thereof with an acid:
