Provided that: the Z1 is divalent radical comprising -S, -SO-, -SO2, when R1a is CH3; #when Z1, Z2 represents a covalent bond, then R1a, R2a represents a divalent radical; and #at least one of the R1a and R2a is a cationic radical. Independent claims are included for: (1) a process of oxidation coloring of keratin fibers, comprising applying the composition on fibers, in the presence of an oxidizing agent during a sufficient time to develop desired color; and (2) a device with several compartments comprising a first compartment containing the dyeing composition and a second compartment containing oxidizing agent.
