Description

TINCTORIAL COMPOSITION COMPRISING A PARA-PHENYLENE DIAMINE SECONDARY OXIDATION BASE AND A NACRANT AGENT

The invention relates to a dye composition comprising at least one particular para-phenylenediamine oxidation base and at least one pearlescent agent. The invention also relates to a process for dyeing keratinous fibers, in particular human fibers such as the hair, using this composition, as well as devices with several appropriate compartments. It is known to dye keratin fibers and in particular human hair with dye compositions containing oxidation dye precursors, generally known as oxidation bases, such as ortho or para-phenylenediamines, ortho or para-aminophenols and heterocyclic compounds. These oxidation bases are colorless or weakly colored compounds which, when combined with oxidizing products, can give rise to colored compounds 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 color modifiers, the latter being chosen in particular from aromatic meta-diamines, meta-aminophenols, meta-diphenols and certain heterocyclic compounds such as than indolic compounds. The variety of molecules involved in oxidation bases and couplers, allows to obtain a rich palette of colors.

The so-called "permanent" coloration obtained with these oxidation dyes must also meet a certain number of requirements. Thus, it must be harmless from the toxicological point of view, it must make it possible to obtain shades in the desired intensity and to have good resistance to external agents such as light, bad weather, washing, permanent undulations, sweating and friction.

The dyes must also make it possible to cover the white hair, and finally be the least selective possible, that is to say, to obtain the lowest possible color differences throughout the same keratin fiber, which is in general differently sensitized (ie damaged) between its point and its root.

It is already known to use oxidation bases of the para-phenylene diamine secondary type of formula (I) below for dyeing keratinous fibers, especially the hair. In particular, such a base is disclosed in EP1580184 and EP0055386. This base has the drawbacks of leading to insufficiently intense or chromatic and / or too selective staining. The object of the present invention is to obtain a composition for hair dyeing which has improved dyeing properties in terms of intensity or chromaticity, and / or selectivity and / or resistance to external agents.

This object is achieved with the present invention which relates to a coloring composition of keratinous fibers comprising, in an appropriate dyeing medium,

one or more oxidation bases selected from the compound of formula (I) or its addition salts with an acid,

and one or more pearling agents.
