Abstract

The present disclosure relates to a novel a para-phenylenediamine derivative substituted with a pyrrolidinyl group of formula (I) and the addition salts thereof. The present disclosure also relates to a dyeing composition for keratin fibers comprising the paraphenylene derivative as at least one oxidation base, and to a process for dyeing keratin fibers and a multi-compartment kit using the claimed dye composition. Such a composition makes it possible to obtain a chromatic, powerful, unselective and fast coloration of keratin fibers.
