  <B>Zusatzpatent</B> zum Hauptpatent Nr. 243336.    Verfahren     zur        Herstellung    eines     metallisierbaren        Trisazofarbstoffes:       Das vorliegende Patent     betrifft        ein    Ver  fahren zur Herstellung eines neuen     metalli-          sierbaren        Trisazofarbstoffes    und ist dadurch  gekennzeichnet, dass man den Kupfer  komplex des     Trisazofarbstoffes,    aus.

   1     Mol          3,3'-Dimethoxy-4,4'-,diaminodiphenyl    alka  lisch mit 1     Mol        2-Amino-8-oxynaphthalin-6-          sulfonsäure    kombiniert,     weiterdiazotiert    und  mit 2     Mol        1,8-Dioxynaphthalin-4-sulfonsäure     gekuppelt mit konzentrierter Salzsäure     ent-          kupfert.     



  <I>Beispiel:</I>  1 Teil des Kupferkomplexes des     Trisazo-          fa,rbstoffes    aus 1     Mol        3,3'-Dimethoxy-4,4'-di-          aminodiphenyl    alkalisch mit 1     Mol        2-Amino-          8-oxynaphthalin-6-sulfonsäure        kombiniert,          weiterdiazotiert    und mit     2M01        1,8-Dioxy-          na.phtha_lin-4-.sulfonsäure    gekuppelt, wird in  6 Teilen Wasser aufgeschlämmt,

   bei Siede  temperatur     langsam        mit    10 Teilen konzen  trierter Salzsäure versetzt und 3/4     Stunden     am Rührwerk rückfliessend gekocht und dann       filtriert.    Der kupferfreie Farbstoff wird in  das Na-Salz umgewandelt und getrocknet.  Er stellt so ein schwarzes Pulver dar, das    sich in Wasser und in konzentrierter Schwe  felsäure mit blauer Farbe löst. Der Farb  stoff färbt Zellwolle dunkelblau, mit Kup  fer- und Chromsalzen nachbehandelt     licht-          und    waschecht grau.



  <B> Additional patent </B> to main patent no. 243336. Process for the production of a metallizable trisazo dye: The present patent relates to a process for the production of a new metallizable trisazo dye and is characterized in that the copper complex of the trisazo dye is made .

   1 mole of 3,3'-dimethoxy-4,4 '-, diaminodiphenyl alka cally combined with 1 mole of 2-amino-8-oxynaphthalene-6-sulfonic acid, further diazotized and coupled with 2 moles of 1,8-dioxynaphthalene-4-sulfonic acid concentrated hydrochloric acid decoppered.



  <I> Example: </I> 1 part of the copper complex of Trisazofa, dye from 1 mol of 3,3'-dimethoxy-4,4'-di-aminodiphenyl alkaline with 1 mol of 2-amino-8-oxynaphthalene-6 -sulfonic acid combined, further diazotized and coupled with 2M01 1,8-Dioxy- na.phtha_lin-4-.sulfonic acid, is suspended in 6 parts of water,

   slowly mixed with 10 parts of concentrated hydrochloric acid at boiling temperature and refluxed for 3/4 hours on a stirrer and then filtered. The copper-free dye is converted into the sodium salt and dried. It is a black powder that dissolves in water and concentrated sulfuric acid with a blue color. The dye dyes rayon staple dark blue, treated with copper and chromium salts, lightfast and washable gray.

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen metallisierbaren Trisazofarbstoffes, dadurch gekennzeichnet, dass man den Kupferkom plex des Trisazofarbstoffes aus 1 Mol 3,3' Dimethoxy - 4,4' - diaminodiphenyl alkalisch mit 1 Mol 2-Amino-8-oxynaphthalin-6-sul- fonsäure kombiniert, weiterdiazotiert und mit 2 Mol 1, PATENT CLAIM: A process for the preparation of a new metallizable trisazo dye, characterized in that the copper complex of the trisazo dye is made from 1 mol of 3,3 'dimethoxy - 4,4' - diaminodiphenyl alkaline with 1 mol of 2-amino-8-oxynaphthalene-6-sul - Phonic acid combined, further diazotized and with 2 mol 1, 8-Dioxynaphthalin-4-sulfonsäure ge kuppelt mit konzentrierter Salzsäure ent- kupfert. Der neue kupferfreie Farbstoff stellt in Form seines Natriumsalzes ein schwarzes Pulver dar, das sich in Wasser und in kon zentrierter Schwefelsäure mit blauer Farbe löst. Der Farbstoff färbt Zellwolle dunkel blau, mit Kupfer- und Chromsalzen nach behandelt licht- und waschecht grau. 8-Dioxynaphthalene-4-sulfonic acid coupled with concentrated hydrochloric acid, decoppered. The new copper-free dye is a black powder in the form of its sodium salt, which dissolves in water and in concentrated sulfuric acid with a blue color. The dye dyes rayon dark blue, treated with copper and chromium salts gray after being treated with light and washable properties.
