실험 절차

31.9 g of 2-amino-5-hydroxynaphthalene-1,7-disulphonic acid are condensed by the procedure of Example 1 with trifluorotriazine and then with morpholine. A diazo compound obtained in the usual manner by direct diazotisation of 38.3 g of 2-aminonaphthalene-1,5,7-trisulphonic acid is added to the resulting suspension of the monofluorotriazinyl compound at 5° to 10°, while simultaneously maintaining the pH at 7.0 to 7.5 by sprinkling in sodium bicarbonate. After coupling is complete, the dyestuff of the formula ##STR17## is salted out, filtered off with suction, dried and milled.
