Pyrrolidinyl-substituted para-phenylenediamine derivatives substituted with a cationic radical, and use of these derivatives for dyeing keratin fibres

摘要

Novel pyrrolidinyl-substituted para-phenylenediamine derivatives comprising a cationic radical, the dye compositions comprising them and the process for dyeing keratin fibers using these compositions, making it possible to obtain a chromatic, powerful, unselective and fast coloration of keratin fibers.
