Procedure

3,10-bis(4-amino-3-sulphophenylamino)-6,13-dichlorotripheno dioxazine-4,11-disulphonic acid (M.I. 2585, 25.85 g, 0.01M) was dissolved in water (300 ml) at pH 7. A solution of N-(2,4-dichlorotriazin-6-yl) methanesulphonmethylamide (5.93 g, 0.02M) in acetone (80 ml) was added and the mixture stirred at 25° C. and pH 7 for 3 hours. Salt (5% w/v) was added with stirring and the precipitated solid was collected, washed and dried. Yield 1.7 g, M.I. 1472.
