H--E (8).

For instance, it is possible

(a) to condense 1 mole of a dyestuff of the formula (5) with 2 moles of a triazine of the formula (6) and then to react the bis-acylation product with 2 moles of an amine of the formula (8); or

EXAMPLE 1

14.8 g of cyanuric fluoride are added dropwise to an ice-cold neutral solution of 17.3 g of o-sulphanilic acid in 400 ml of water in the course of 10 minutes during which the pH is maintained between 5.5 and 6.5 by simultaneously adding 15% strength sodium carbonate solution. After complete acylation, a suspension of 0.045 mole of the dyestuff of the formula ##STR29## in 400 ml of water is added at 0.degree.-5.degree. C. By adding 2N sodium hydroxide solution the condensation is carried out at 0.degree.-5.degree. C. and pH 7.5-8.0.

The diaminotriphendioxazine dyestuff used in Example 1 can be obtained by one of the three following methods:

(a) 34.55 g (0.05 mole) of the dianilide of the formula ##STR51## are introduced at 25.degree. to 40.degree. C. into 800 g of 25% strength oleum. The temperature is raised to 50.degree.-60.degree. C. in the course of 15 minutes, and the mixture is stirred until the cyclisation has ended (as can be monitored by thin layer chromatography). After cooling down to room temperature the mixture is discharged onto 2 kg of ice-water. The mixture is filtered with suction, and the paste on the filter is stirred into 1 l of ice-water. The pH is adjusted to 5-6 by sprinkling in sodium hydrogencarbonate. The precipitate is filtered off with suction and is washed with water. The dyestuff has the following formula ##STR52##

(b) 34.55 g of the dianilide are introduced with stirring at 20.degree. to 25.degree. C. into 400 g of 20% strength oleum in the course of 15 minutes. 22.8 g of ammonium persulphate are then added at 30.degree. C. in 7 equal-size portions at one hour intervals. Afterwards the mixture is stirred at 20.degree. to 30.degree. C. for 1 hour. The reaction mixture is discharged onto 1 kg of ice-water. The further working-up procedure is as described in (a).

(c) 34.55 g of the dianilide are introduced at 20.degree. to 30.degree. C. with thorough stirring into a mixture of 80 ml of 20% strength and 60 ml of 65% strength oleum in the course of 40 minutes. 1 g of potassium iodide is added at 20.degree. C. The mixture is stirred at 20.degree. C. to 23.degree. C. for 45 minutes, and the melt is then added to 1000 g of ice and 200 ml of water, so that the temperature does not rise above 10.degree. C. The further working-up procedure is as described in (a). The dyestuff has the formula shown in Example a.

The dianilide used as a starting material in Examples a, b and c can be prepared in conventional manner as follows: ##STR53##

EXAMPLE 2

110.3 g of the triphendioxazine dyetsuff of the formula ##STR54## are dissolved in 2 l of ice-water under neutral conditions. 27 g of trifluorotriazine are added dropwise at 0.degree. C. in the course of 20 minutes during which the pH is maintained between 5.5 and 6.5 by the simultaneous addition of dilute sodium carbonate solution. After the acylation has ended (if free amino groups are still present, a little more trifluorotriazine is added), a neutral solution of 34.6 g of m-sulphanilic acid in 100 ml of water is added, the hydrofluoric acid which is liberated being neutralised with dilute sodium carbonate solution (pH 6-7), while the temperature is allowed to rise to 10.degree.-15.degree. C. The dyestuff is salted out by adding 20% by volume of sodium chloride. Filtering with suction, drying at 60.degree. C. in a vacuum drying cabinet and grinding produce a blue dyestuff powder which dyes cotton in brilliant blue shades (Hue Indicator No. 14). The dyestuff has the formula ##STR55##
