THE PRESENT INVENTION RELATES TO A PROCESS FOR THE SULPHONOATION OF AN AROMATIC OR HETEROCYCLIC POLYNUCLEAR AMINE WHICH COMPRISES TREATING THE AMINE, DISPERSED OR DISSOLVED IN AN AQUEOUS SOLUTION OF A WATER-SOLUBLE SALT OF SULPHUROUS ACID, WITH AN OXIDISING AGENT OF WHICH THE OXIDATION POTENTIAL, MEASURED AT 20*C, AND PH( WITH RESPECT TO THE NORMAL HYDROGEN ELECTRODE, IS BETWEEN +0.4 AND +0.7 VOLT, THE PH OF THE MEDUM BEING MAINTAINED APPROXIMATELY CONSTANT AT A VALUE BETWEEN 3 AND 9.5. IT ALSO RELATES TO NEW SULPHONATED POLYNUCLEAR AMINES AND TO AZO DYESTUFFS HAVING ONE OF THE FORMULAE:
