专利说明:

[0001] The present invention relates to a method for dyeing keratinous fibers, in particular human keratinous fibers such as the hair, in which said fibers are treated with a hair-dyeing process employing at least one orthodiphenol, a titanium derivative and a carboxylic acid. from one or more cosmetic compositions comprising a) one or more orthodiphenol (s), b) one or more particular compound (s) comprising titanium, c) one or more acid (s) and d) optionally a or more chemical oxidizing agent (s) such as hydrogen peroxide or one or more hydrogen peroxide generator system (s). It is known to obtain so-called "permanent" dyes with dyeing compositions containing oxidation dye precursors, generally called oxidation bases, such as ortho- or para-phenylenediamines, ortho- or para-aminophenols and compounds. heterocyclic. 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 can be varied by combining these oxidation bases 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 indole compounds. This oxidation dyeing process consists in applying to the keratinous fibers, bases or a mixture of bases and couplers with hydrogen peroxide (H 2 O 2 or hydrogen peroxide) as an oxidizing agent, to be allowed to diffuse, then to rinse the fibers. The resulting colorations are permanent, strong, and resistant to external agents, including light, weather, washing, perspiration and friction. However, commercial hair colourants that contain them generally have the disadvantage of staining clothing, lead to odor and comfort problems, and degrade keratin fibers. This is particularly the case with oxidation dyes. In the field of coloring, it is also known to color keratin materials such as hair or skin from orthodiphenol compounds in the presence of a metal salt, especially manganese (Mn) and / or zinc (Zn) . In particular, the patent applications FR 2814943, FR 2814945, FR 2814946 and FR 2814947 provide compositions for coloring the skin or keratinous fibers, comprising a dye precursor which contains at least one orthodiphenol, salts and oxides of Mn. and / or Zn, alkaloids of hydrogen carbonate type in a particular ratio Mn, Zn / hydrogen carbonate and optionally an enzyme. According to these documents, it is possible to obtain dyes of keratin materials with oxygen from the air or any system generating oxygen. However, the colorations obtained are insufficiently powerful, intense and / or are not very stubborn, especially in the case of hair fibers. Furthermore, it is known to use acid-level metals for dyeing keratinous fibers in amounts similar to those used for dyes by using an etching process, which consists in preparing the fibers before dyeing to to obtain stubborn hues (Ullmann's Encyclopedia "Metal and Dyes", 2005 § 5.1, p 8). However, this process generally has the disadvantage of not always respecting the cosmetics of the keratin fiber. Other documents describe the use of orthodiphenols associated with salts of Mn, Zn and other metal salts including titanium salts and a chemical oxidizing agent (FR297673, WO2011 / 086284, WO2011 / 086282, and FR2951374) . Nevertheless, improvements still need to be made, especially in terms of color tenacity with regard to shampoos and sweat. There is therefore a real need to develop staining processes that make it possible to obtain more powerful and / or stubborn stains from orthodiphenols, in particular from natural extracts rich in orthodiphenols and less aggressive for keratinous fibers. In particular, there is a need to obtain colorings which are satisfactorily resistant to external agents (light, bad weather, shampoos, sweat) which are stubborn and homogeneous, ie having a low selectivity of the coloration between the root and the tip, while remaining powerful and / or chromatic. This goal (s) is (are) achieved by the present invention which relates to a process for dyeing keratinous fibers, in particular human keratin fibers such as the hair, in which said fibers are treated, in one or more steps, by one or more cosmetic compositions containing, taken together or separately in the one or more compositions, the following ingredients: a) one or more orthodiphenol (s); b) one or more inorganic salt (s) of titanium or one or more alkoxytitanium (s), in which (s) Titanium is in particular of oxidation degree 2, 3 or 4 noted Ti (II), Ti (III) or Ti (IV), preferably Ti (III) or Ti (IV); c) one or more carboxylic acid (s) of the following formula (I) or one of their salts: ## STR2 ## in which: A represents a monovalent group when n is 0 or polyvalent when n is 0 HO35 greater than or equal to 1, hydrocarbon comprising 1 to 50 carbon atoms, saturated or unsaturated, cyclic or non-cyclic, aromatic or non-aromatic, optionally interrupted by one or more heteroatoms and / or optionally substituted especially by one or more hydroxyl groups; preferably A represents a monovalent (C1-C6) alkyl or polyvalent (C1-C6) alkylene group optionally substituted by one or more hydroxyl groups; n represents an integer inclusive between 0 and 10, preferably n is between 0 and 5, such as between 0 and 2; d) optionally one or more chemical oxidizing agent (s), especially chosen from hydrogen peroxide or one or more hydrogen peroxide generator system (s); it being understood that at least one of the compositions used in the dyeing process is at acidic pH, i.e. less than 7.0, preferably less than 5, particularly at a pH between 0 and 4 inclusive.

Another subject of the invention is a cosmetic composition comprising the ingredients a), b), c) and optionally d) as defined above. Another object of the present invention relates to a multi-compartment device comprising the ingredients a), b), c) and possibly d) distributed in several compartments. The multi-compartment device or "kit" is suitable for carrying out the coloring process according to the invention. The process according to the invention has the advantage of coloring human keratin fibers, with stubborn coloring results. In particular, the dyeing method according to the invention makes it possible to lead to colorings resistant to washing, transpiration, sebum and light without altering the fibers. The resistance to perspiration is particularly good. In addition, the coloring process used makes it possible to induce a "rise" and / or power of the satisfactory coloration.
