ABSTRACT:
The present invention relates to the use, for dyeing keratin fibres, of at least one aliphatic cationic amine and of at least one compound chosen front an aldehyde, a ketone, a quinone and a diiminoisoindoline or 3-aminoisoindolone derivative, to dye compositions comprising a combination of these compounds, to dyeing processes using the said compounds and to a multi-compartment device containing these compounds.
It is known practice, for the dyeing of keratin fibres, and in particular of human keratin fibres such as the hair, to use direct dyes or coloured substances which give the fibre a temporary or semi-permanent coloration, of low dyeing power, which is generally removed by washing. The ranges of shades obtained by these direct processes are generally limited. It is also known practice to use oxidation dyes (oxidation bases and couplers) which are compounds which are initially colourless or weakly coloured and which, under the action of an oxidizing agent, generate coloured compounds by a process of oxidative condensation. Compared with direct colorations, oxidative colorations are permanent, powerful and withstand external agents (light, bad weather, washings perspiration and rubbing). Nevertheless, the use of the oxidizing agent can harm the keratin fibres and makes the processes for carrying out the oxidative dyeing operations relatively complex.
The Applicant has just discovered a novel dyeing process, which does not involve a process of oxidative development of dyes, and which gives a wide range of shades.
The compounds used by the Applicant are small molecules which can penetrate into keratin easily. The Applicant has found, surprisingly, that these compounds can then condense to form chromophores or dyes, bulkier molecules which remain trapped inside the keratin.
The Applicant has thus found that the dyes obtained withstand shampooing and perspiration and are stable with respect to light, bad weather and chemical agents. These colorations withstand shampooing particularly well. The Appliicint has, in a way, discovered a novel dyeing process which has the advantages of so-called oxidation dyeing without exhibiting its drawbacks, since no oxidizing agent is used.
One subject of the present invention is thus the use, for dyeing keratin fibres, of an aliphatic cationic amine and of a compound chosen from an aldehyde, a ketone, a quinone and a diiminoisoindoline or 3-aminoisoindolone derivative.
Another subject of the invention relates to dye compositions comprising these compounds.
A subject of the present invention is also a process for dyeing keratin fibres, which consists in applying an aliphatic cationic amine and a compound chosen from an aldehyde, a ketone, a quinone and a diiminoisoindoline or 3-aminoisoindolone derivative to the fibres, either simultaneously, in the form of a mixture prepared at the time of use, or successively.
Another subject of the invention also consists of a dyeing agent for carrying out the process of the invention.
Other subjects of the invention will become apparent in the light of the description and the examples which follow.
The main subject of the present invention is thus the use, for dyeing keratin fibres, in particular human keratin fibres such as human hair, of at least one aliphatic cationic amine and of at least one compound chosen from an aldehyde, a ketone, a quinone and a diiminoisoindoline or 3-aminoisoindolone derivative, in order to obtain, by reaction without an oxidizing agent, a coloration of the said keratin fibres.
