Description

COMPOSITION OF DYEING FOR QUEKATINIC FIBERS WITH A CATIONIC DIRECT COLORING AND A SUBSTANTIVE POLYMER The invention relates to a dyeing composition for keratin fibers, in particular for human keratin fibers such as hair, comprising, in a medium suitable for dyeing, at least one direct cationic dye of the given formula, and at least one polymer particular cationic or amphoteric noun. The invention also has as its object the dyeing methods and devices which use the said composition. In the capillary field, two types of coloration can be distinguished. The first is the semi-permanent or temporary coloration, or direct coloring, which uses dyes that are able to contribute to the natural coloration of the hair, a more or less pronounced color modification resistant eventually to several shampoos. These dyes are called direct dyes; they can be carried out with or without oxidizing agents. In the presence of an oxidant, the purpose is to obtain a clarified coloration. The rinsed coloration is carried out by applying the extemporaneous mixture of a direct dye and an oxidant on the hair, and it is possible in particular to obtain by refining REF .: 30188 of the melanin of the hair, an advantageous effect such as a uniform color in the case of hair. gray hair or highlight the color in the case of naturally pigmented hair. The second is the permanent coloration or oxidation coloration. This is carried out with dyes called "oxidation" which comprise oxidation dye precursors and copulators. Oxidation staining precursors, commonly called "oxidation base", are initially colorless or weakly colored compounds that develop their dyeing power in the hair in the presence of oxidizing agents added at the time of use, leading to the formation of colored compounds and colorants. The formation of these colored compounds and dyes, either by an oxidative condensation of the "oxidation bases" on themselves, or by an oxidative condensation of the "oxidation bases" on coloring modifying compounds commonly called "couplers" and generally present in the dyeing compositions used in oxidation dyeing. To vary the shades obtained with the indicated oxidation dyes, or enrich them with reflections, it happens that they are added direct dyes.

Among the cationic direct dyes available in the field of dyeing of particularly human keratin fibers, the compounds whose structure will be developed in the text that follows are already known; However, these dyes lead to colorations that have still insufficient characteristics, while at the same time in the plane of homogeneity of the color distributed along the fiber ("unisson") (uniformity), it is said then that the coloration is too selective, and in the plañe of the tenacity, in terms of resistance to the various aggressions that can experience the hair (light, bad weather, lavas with shampoo). However, after important investigations carried out on the subject, the applicant firm has now discovered that it is possible new compositions for the dyeing of keratin fibers capable of leading to less selective colorations and that better resist the various aggressions that can experiencing the hair, associated with at least one particular cationic or amphoteric substantive polymer with at least one known cationic direct dye of the prior art and of the formula (I) defined below.
