Infolge ihrer großen Kupplungsehergie läßt sich diese Diazoverbindung auch mit Verbindungen vereinigen, die üblicherweise nicht zur Herstellung von Azofarbstoffen Verwendung finden.^ groups included. As a result of their great clutch hergy this diazo compound can also be combined with compounds that are customary cannot be used for the production of azo dyes.
Das 2-Amino-4-methyl-5-cyanthiazol läßt sichThe 2-amino-4-methyl-5-cyanthiazole can

Die neuen Farbstoffe eignen sich z. B. zum Färben von Acetatkunstseide, vollsynthetischen Fasern, wie Polyamidfasern, Polyurethanfasern, Polyesterfasern oder Polyacrylnitrilfasern, sowie Lacken und Kunststoffen. Die mit den neuen Farbstoffen erhältlichen Färbungen zeichnen sich durch große Klarheit und gute Lichtechtheit aus. Den aus der deutschen Patentschrift 789 850 bekannten Farbstoffen sind die neuen Farbstoffe in der Lichtechtheit deutlich überlegen.The new dyes are suitable for. B. for dyeing acetate rayon, fully synthetic fibers, such as polyamide fibers, polyurethane fibers, polyester fibers or polyacrylonitrile fibers, as well as paints and plastics. The one with the new dyes available dyeings are characterized by great clarity and good lightfastness. The one from the German Patent 789 850 known dyes are the new dyes in light fastness clearly superior.
