Description

  

  Verfahren zur Herstellung eines     Diäzotierängsfarbstoffes.       Es wurde gefunden, dass     durch    Einwirkung  von     Formaldehydbisulfit    auf den     Farbstoff,     erhalten durch     Kombinieren    von 1     Mol.        tetrazo-          tiertem    3 :     3'-Diainino-4        .#        4'-ditolylmethan    mit       Mol:    1 :     2-(3'-Aminophenyl)-riapbtimidazol-*          5-oxy-7-srilfosäure,    ein leichtlöslicher     Farbstoff     erhalten wird.

   Dieser     Farbstoff    färbt     uuge-          beizte    Baumwolle     gelbstichig    Bordeaux; durch       r        .Diazotieren    der Färbung und Kuppeln mit       ss-Naphtal    wird ein sehr waschechtes, volles  Blaurot erhalten.

     <I>Beispiel:</I>  50 Teile des     Farbstoffes    aus 1     Mol.        tetra-          zotiertem        3:3'-Diainino-4:4'-ditolylmetliän     und 2     Mol.    1     :

  2-(3'-Amiriopheriyl)-riaphtirnid-.          azol-5-oxy-7-srilfosäure    werden mit 300 Teilen       Wasser    angerührt und     finit    einer vorbei zum  Kochen     erhitzten    Mischung von 28,6 'feilen       Natriumbisulfitlösung        h,    400o und 3,3 Teilen    Formaldehyd in Form einer wässerigen 30  bis     40 /oigen    Lösung versetzt.- Man erhitzt  die     112asse-während        -einer    Stunde zum Sieden,  salzt aus, filtriert     ünd    trocknet.



  Process for the production of a longitudinal dyestuff. It has been found that by the action of formaldehyde bisulfite on the dye, obtained by combining 1 mole of tetrazolated 3: 3'-diainino-4. # 4'-ditolylmethane with mole: 1: 2- (3'-aminophenyl) -riapbtimidazole- * 5-oxy-7-srilfosäure, a readily soluble dye is obtained.

   This dye gives off-stained cotton a yellowish tinge of Bordeaux; by r. diazotizing the color and domes with SS-naphthalene a very washfast, full blue-red is obtained.

     <I> Example: </I> 50 parts of the dye from 1 mol. Tetrazotized 3: 3'-diainino-4: 4'-ditolylmetliän and 2 mol. 1:

  2- (3'-Amiriopheriyl) -riaphtirnid-. azole-5-oxy-7-sulfonic acid are mixed with 300 parts of water and finitely added to a mixture, heated to boiling point, of 28.6 'file sodium bisulfite solution, 400o and 3.3 parts of formaldehyde in the form of an aqueous 30 to 40% solution - The mixture is heated to the boil for one hour, salted out, filtered and dried.
