EMI0001.0034
    The diazo compound produced, separated and mixed with ice water flows at 5 to <B> 10 '</B> to form a well-stirred solution of 1052 wt.

  Not part of the condensation product from molar amounts of cyanuric chloride, 1- (4'-amino-bL, nzoyl) -amino-8-oxynaphthalene-4. 6-disulfonic acid, 4-amino-4'-oxy-azo-benzene-3'-carboxylic acid and 4-aminobenzoic acid. The coupling sets in immediately, the solution turns deep green and will soon be over.



  When dry, the dye is a dark, bronze-shimmering powder that dissolves in water with a green color and turns into glowing from the Glauber's salt soda bath. yellowish green tones on the vegetable fibers. The coloring has a remarkable lightfastness.

PATENTANSPRUCH: Verfahren zur Darstellung eines grünen Direktfarbstoffes, dadurch gekennzeichnet, dass man die diazotierte Aminoazoverbindung aus diazotierter 1-Aminobenzol-2.5-disulfo- säure und 1-Amino@-?-methylmercaptonaph- talin mit dem Kondensationsprodukt aus molaren Mengen Cyanurchlorid, 1-(4'-Amino- benzo51)-Amino-8-oxynaphtalin-4 . PATENT CLAIM: Process for the preparation of a green direct dye, characterized in that the diazotized aminoazo compound from diazotized 1-aminobenzene-2,5-disulfonic acid and 1-amino @ -? - methylmercaptonaphthalene with the condensation product of molar amounts of cyanuric chloride, 1- ( 4'-amino-benzo51) -amino-8-oxynaphthalene-4. 6-disulfo- säure, 4-Amino-4'-oxy-azo-benzol-3'-carbon- säure und 4-Aminobenzoesäure kuppelt. Der Farbstoff stellt in getrocknetem Zu stand ein dunkles, bronzeglänzendes Pulver dar, das sich mit grüner Farbe in Wasser löst und aus dem Glaubersalz-Sodabatl in leuchtenden, gelbstichig grünen Tönen auf die pflanzliche Faser zieht. Die Färbungen besitzen eine bemerkenswerte Lichtechtheit. 6-disulfonic acid, 4-amino-4'-oxy-azo-benzene-3'-carboxylic acid and 4-aminobenzoic acid are coupled. When dry, the dye is a dark, bronze-shimmering powder that dissolves in water with a green color and draws it from the Glauber's salt sodabatl in bright, yellow-tinged green tones onto the vegetable fiber. The dyeings have a remarkable lightfastness.
