Definitions

• the subject of the invention is a composition for the oxidation dyeing of keratin fibers, and in particular human keratin fibers such as the hair, comprising as oxidation base a 1- (4-aminophenyl) pyrrolidine substituted for less in positions 2 and 5.
• oxidation bases 15,6-dihydroxyindole derivatives, 5,6-dihydroxyindoline derivatives generally called oxidation bases.
• the precursors of oxidation dyes, or oxidation bases are colorless or weakly colored compounds which, associated with oxidizing products, can give rise, through an oxidative condensation process, to colored and coloring compounds.
• couplers or color modifiers the latter being chosen in particular from aromatic meta-diamines, meta-aminophenols, meta- hydroxyphenols and certain heterocyclic compounds such as, for example, pyrazolo derivatives [1, 5-b] -1, 2,4, -triazoles, pyrazolo derivatives [3,2-cJ-1, 2,4, -triazoles ,. pyrazolo derivatives [1,5-a] pyrimidines, pyridine derivatives, pyrazol-5-one derivatives, indoline derivatives and indole derivatives.
• the so-called "permanent" coloration obtained thanks to these oxidation dyes must moreover satisfy a certain number of requirements. Thus, it must be without drawbacks from the toxicological point of view, it must make it possible to obtain nuances in the desired intensity, to have good resistance to external agents (light, bad weather, washing, permanent waving, perspiration, friction).
• the dyes must also make it possible to cover white hair, and finally be the least selective possible, that is to say allow to obtain the smallest possible color differences throughout the same keratin fiber, which can be in differently sensitized effect (ie damaged) between its tip and its root. They must also have good chemical stability in the formulations. They must have a good toxicological profile.
• NN-bis- ( ⁇ -hydroxyethyl) paraphenylenediamine and 2- ( ⁇ -hydroxyethyl) paraphenylenediamine have the disadvantage of leading to a less wide variety of shades and of imparting less color intensity, less uniformity. to hair than para-phenylenediamine and 4-amino-2-methylaniline. It is the same for 2- (hydroxyalkoxy) -paraphenylene diamine which give the hair colors which evolve and change over time.
• the oxidation bases which are too oxidizable and which react with couplers according to accelerated reaction rates, generally lead to the formation of dyes outside the keratin fiber.
• the intensities, tenacity and uniformity of the colorings thus obtained on the hair are generally insufficient.

• compositions containing derivatives of paraphenylenediamine having a nitrogen atom included in a functionalized pyrrolidine cycle as described in patent application JP 11158048 do not make it possible to confer on the hair dyeing results equivalent to those obtained with para -phenylenediamine or paratoluenediamine.
