      zusatzpatent        zutn    Hauptpatent Nr. 110287.    Verfahren zur Herstellung eines neuen Farbstoffes.    Es     wurde    gefunden, dass man einen neuen  Farbstoff erhält, wenn man     diazotiertes        4-          Chlor-6-nitro-2-amino-l-phenol    mit     3-Amino-          naphthalin-1,8-dikarbonsäure        vereinigt.    Der  neue Farbstoff bildet ein braunes Pulver,  das sich in Wasser mit braunroter, in Schwe  felsäure mit rotbrauner Farbe löst. Er färbt  Wolle aus saurem Bade in braunen Tönen,  welche beim     Nachchromieren    nach olive um  schlagen.

   Im Chromdruck auf Baumwolle  erzeugt er graue Töne.    <I>Beispiel:</I>    <B>10,7</B> Teile     3-Aminonaphthalin-1,8-dikar-          bonsäureanhydrid    werden mit Hilfe von 10  Teilen 30     %iger    Natronlauge in<B>150</B> Teilen  Wasser heiss gelöst, mit 10 Teilen Soda ver  setzt, abgekühlt und mit der aus 9,4 Teilen       4-Chlor-6-nitro-2-amino-l-phenol    hergestell-         ten        Diazoverbindung    versetzt. Nach erfolg  ter Kupplung wird der Farbstoff     ausgesal-          zen,        filtriert    und getrocknet.



      additional patent 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-chloro-6-nitro-2-amino-1-phenol is combined with 3-amino-naphthalene-1,8-dicarboxylic acid. The new dye forms a brown powder that dissolves in water with a brownish-red color, and in sulfuric acid with a reddish-brown color. It dyes wool from acid baths in brown tones, which turn to olive when they are chrome-plated.

   In the chrome print on cotton it creates gray tones. <I> Example: </I> <B> 10.7 </B> parts of 3-aminonaphthalene-1,8-dicarboxylic acid anhydride are converted into <B> 150 </B> with the aid of 10 parts of 30% sodium hydroxide solution Parts of hot water are dissolved, 10 parts of soda are added, the mixture is cooled and the diazo compound prepared from 9.4 parts of 4-chloro-6-nitro-2-amino-1-phenol is added. After coupling has taken place, the dye is salted out, filtered and dried.

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen Farbstoffes, dadurch gekennzeichnet, dass man diazotiertes 4-Chlor-6-nitro-2-amino-l- phenol mit 3-Aminonaphthalin-1,8-dikarbon- säure vereinigt. Der neue Farbstoff bildet ein braunes Pulver, das sich in Wasser mit braunroter, in Schwefelsäure mit rotbrauner Farbe löst. Er färbt Wolle aus saurem Bade in braunen Tönen, welche beim Nachchro- mieren nach olive umschlagen. Im Chrom druck auf Baumwolle erzeugt er graue Töne. PATENT CLAIM: Process for the production of a new dye, characterized in that diazotized 4-chloro-6-nitro-2-amino-1-phenol is combined with 3-aminonaphthalene-1,8-dicarboxylic acid. The new dye forms a brown powder that dissolves in water with a brownish-red color, and in sulfuric acid with a reddish-brown color. It dyes wool from an acid bath in brown tones, which change to olive when it is re-chromed. In the chrome print on cotton, it creates gray tones.
