Abstract
The disclosure relates to novel para-phenylenediamine derivatives containing a cyclic diaza group, substituted with a cationic radical, as well as to the dye compositions comprising them, and to the method of dyeing keratin fibers using these compositions.The present invention may make it possible to obtain a chromatic, strong, relatively unselective and fast coloration on keratin fibers.
