  Verfahren zur Darstellung von blauroten Farblacken. 



   Es wurde gefunden, dass man aus dem durch Kupplung von tetrazotiertem   w-Tolidin   mit 2 Molekülen   2-Naphtol-3#6-disulfosäure erhaltenen Diazofarbstoff nach   den in der Lackfärberei üblichen Methoden wertvolle neue Farblacke erhält, die sich durch ihre   schöne,   reine blaurote Farbe auszeichnen. 



   In der Technik fanden bisher zur Herstellung derartiger Lacke   hauptsächlich   die blaustichigen Ponceau-Marken, z.   B.     Ponceau @ R (= Aminoazobenzol -# ss-Naphtoltrisulfo-     säure) Verwfndung, die aber den grossen   Nachteil   haben,   dass sie sich mit den zur LackbildungangewandtenMetallsalzennichtvollständigfällenlassenausserdemeinentrüben Farbton besitzen, der namentlich in Mischung mit basischen Farbstoffen zur Erzeugung von    ätontönen wonig   ausgiebig ist und sie zur Herstellung von solchen Tönen nur in beschränktemMasseAnwendungfindenlässt. 



     Die neufn l. acke   weisen Eigenschaften auf, die sie dazu bestimmt sein   fassen,   eine grosse Lücke in der Reihe der technisch angewandten Farblacke auszufüllen. Die neuen Lacke sind besonder sdadurch wertvoll, dass sie bei der Herstellung vollständig gefällt

  Process for the representation of bluish-red colored lakes.



   It has been found that the diazo dye obtained by coupling tetrazotized w-tolidine with 2 molecules of 2-naphthol-3 # 6-disulfonic acid, using the methods customary in paint dyeing, gives valuable new colored lakes, which have a beautiful, pure blue-red color distinguish.



   In the art, mainly the bluish Ponceau brands, z. B. Ponceau® R (= aminoazobenzene - # ss-naphtholtrisulphonic acid), but they have the major disadvantage that they cannot be completely precipitated with the metal salts used to form varnishes it has only limited use in the production of such tones.



     The neufn l. acke have properties which they believe are intended to fill a large gap in the range of technically applied color lakes. The new paints are particularly valuable in that they are completely pleasing during manufacture
