Bevorzugt sind Me'.hoxy für R und Chlor für X.Preferred are Me'.hoxy for R and chlorine for X. Zur Herstellung der Verbindungen der Formel ! kann man eine Verbindung der FormelFor the preparation of the compounds of the formula! one can get a compound of the formula SO3HSO 3 H HO3SHO 3 S SO3HSO 3 H mit einer Verbindung der Formelwith a compound of the formula N NN N acylieren. Einzelheiten der Herstellung können dem Beispiel entnommen werden, in dem sich Teile und Prozente, sofern nicht anders vermerkt, auf das Gewicht beziehen. Die Farbstoffe der Formel I eignen sich zum Färben von cellulosehaltigem Textilmaterial insbesondere nach Kaltfärbeverfahren sowie zum Färben von Leder. Die Färbungen zeichnen sich durch gute Licht- und Naßechtheiten aus. Hervorzuheben ist die hohe Farbstärke der erfindungsgemäßen Farbstoffe.acylate. Details of the production can be found in the example, in which parts and Unless otherwise stated, percentages are based on weight. The dyes of the formula I are suitable for Dyeing of cellulosic textile material, in particular by cold dyeing processes and for dyeing Leather. The dyeings are distinguished by good light and wet fastness properties. The high one should be emphasized Color strength of the dyes according to the invention. Beispielexample Eine stark saure Lösung von 76,7 Teilen 2-Naphthylamin-4,6,8-trisulfonsäure in 400 Teilen Wasser wird mit 250 Teilen Eis und dann mit 13,8 Teilen Natriumnitrit versetzt und IV2 Stunden bei 0 —3°C gerührt. Nach Zugabe von 1 Teil Amidosulfonsäure läßt man eine salzsaure wäßrige Lösung aus 27,4 Teilen 2-Methoxy-5-methyl-1-aminobenzol zufließen und führt die Kupplung bei schwach saurem pH-Wert zu Ende. Man setzt dann eine Suspension aus 37 Teilen Cyanurchlorid in 375 Teile Eiswasser der Farbstofflösung zu und rührt das Gemisch 15 Stunden bei 15 —2O0C und schwach saurem pH-Wert, der durch Zugabe von verdünnter Natronlauge aufrechterhalten wird. Nach beendeter Umsetzung werden in der Farbstofflösung 28 Teile Dinatriumhydrogenphosphat aufgelöst. Der Farbstoff wird dann bei einem pH-Wert von 6,8 mit 360 Teilen Kaliumchlorid ausgefällt, nach 3stündigem Rühren abfiltriert und das Filtergut bei 35° C unter vermindertem Druck getrocknet. Man erhält 224 Teile eines orangefarbenen Pulvers, welches native oder regenerierte Cellulose in kräftigen, licht und naßechten Goldgelb-Tönen färbt.A strongly acidic solution of 76.7 parts of 2-naphthylamine-4,6,8-trisulfonic acid in 400 parts of water is mixed with 250 parts of ice and then with 13.8 parts of sodium nitrite and stirred at 0-3 ° C. for IV2 hours. After adding 1 part of sulfamic acid, an aqueous hydrochloric acid solution of 27.4 parts of 2-methoxy-5-methyl-1-aminobenzene is allowed to flow in and the coupling is completed at a weakly acidic pH. Is then added a suspension of 37 parts of cyanuric chloride in 375 parts of ice water to the dye solution and the mixture is stirred for 15 hours at 15 -2O 0 C and a slightly acidic pH-value, which is maintained by addition of dilute sodium hydroxide solution. After the reaction has ended, 28 parts of disodium hydrogen phosphate are dissolved in the dye solution. The dye is then precipitated with 360 parts of potassium chloride at a pH of 6.8, filtered off after stirring for 3 hours and the filter material is dried at 35 ° C. under reduced pressure. 224 parts of an orange powder are obtained which colors native or regenerated cellulose in strong, light and wet-fast golden yellow tones. Der Farbstoff kann auch durch direkte Zerstäubungstrocknung isoliert werden.The dye can also be isolated by direct spray drying. Führt man die Synthese mit 2-Äthoxy-5-methyl-laminobenzol anstelle des 2-Methoxy-5-methyl-1-aminobenzols analog durch, so erhält man einen Farbstoff mit ähnlichen Eigenschaften.If the synthesis is carried out with 2-ethoxy-5-methyl-laminobenzene instead of the 2-methoxy-5-methyl-1-aminobenzene analogously, a dye is obtained with similar properties.
