Abstract: PROBLEM TO BE SOLVED: To obtain a new cationic sulfonic acid dyestuff excellent in dyeing and printing of a polymeric material, especially a paper. SOLUTION: This cationic sulfonic acid dyestuff is a dyestuff of formula I [A1, A2 are each oxy, carbonyl, a carbonyl-(1-4C alkylimino) or the like; B1, B2 are each an alkylene; R1 is H or a (substituted) 1-4C alkyl; R2 is H, a 1-4C alkyl or the like; R3, R4 are each H, a (substituted) alkyl or the like; Q1 to Q6 are each H, 1-4 non adjacent oxys, imino or the like; An is an anion], e.g. a compound of formula II. The dyestuff of formula I is obtained by diazotizing an amine of formula III, and reacting the obtained product with a coupling component of formula IV preferably at pH 3-5.
