Description

  

  <B>Zusatzpatent</B> zum Hauptpatent Nr. 110287.    Verfahren zur     Iterstellung    eines neuen Farbstoffes.    Es wurde gefunden, dass man einen neuen  Farbstoff erhält, wenn man     diazotierte          4-Amino-l-oxybenzol-2-karbonsäure    mit     3-          Aminonaphthalin-1,8-dikarbonsäure    vereinigt.  Der neue Farbstoff bildet ein braunes Pul  ver, das sich in Wasser mit rotgelber, in  Schwefelsäure mit roter Farbe löst. Er  färbt Wolle aus saurem Bade in roten Tönen,  welche beim     Nachehromieren    schwärzer wer  den.  



  <I>Beispiel:</I>  10,7 Teile     ä-Aminonaphthalin-1,8-dikar-          bonsäureanhydrid    werden mit Hilfe von 10  Teilen 30     %iger    Natronlauge in 150 Teilen  Wasser heiss gelöst, mit 10 Teilen Soda ver  setzt,     abgekühlt    und mit der aus 7,6 Teilen       4-Amino-l-oxybenzol-2-karbonsäure    herge-    stellten     Diazoverbindung    versetzt. Nach be  endeter Kupplung     wird    der Farbstoff aus  gesalzen, filtriert und getrocknet.



  <B> Additional patent </B> to main patent no. 110287. Process for the production of a new dye. It has been found that a new dye is obtained if diazotized 4-amino-1-oxybenzene-2-carboxylic acid is combined with 3-aminonaphthalene-1,8-dicarboxylic acid. The new dye forms a brown powder that dissolves red-yellow in water and red in sulfuric acid. He dyes wool from an acid bath in red tones, which become blacker when remodeling.



  <I> Example: </I> 10.7 parts of α-aminonaphthalene-1,8-dicarboxylic acid anhydride are dissolved in 150 parts of hot water with the aid of 10 parts of 30% strength sodium hydroxide solution, 10 parts of soda are added, the mixture is cooled and mixed with the diazo compound prepared from 7.6 parts of 4-amino-1-oxybenzene-2-carboxylic acid. After coupling has ended, the dye is salted out, filtered and dried.

PATENT CLAIM: Process for the production of a new dye, characterized in that diazotized 4-amino-1-oxybenzene-2-carboxylic acid is combined with - 3-aminonaphthalene-1,8-dicarboxylic acid. The new dye forms a brown powder that dissolves red-yellow in water and red in sulfuric acid. It dyes wool from acid baths in red tones, which become blacker when they are chromed.
