実験手順

31.9 g of 2-amino-5-hydroxy-naphthalene-1,7-disulphonic acid are subjected to a condensation reaction with trifluorotriazine and then with morpholine as described in Example 1. A diazo compound obtained by the customary route by direct diazotisation of 28.3 g of 1-amino-4-methoxy-benzene-2,5-disulphonic acid is added to the resulting suspension of the monofluorotriazinyl compound at 5°-10°, the pH simultaneously being kept at 7.0-7.5 by sprinkling in sodium bicarbonate. When the coupling has ended, the dyestuff of the formula ##STR19## is salted out, filtered off with suction, dried and ground. The red dyestuff powder dissolves readily in water and dyes cotton a brilliant reddish-tinged orange (colour code number 5).
