Description
Zusatzpatent zum Hauptpaient Nr. <B>130699.</B> Verfahren zur Herstellung eines neuen inetallhaltigen Farbstoffes. Es wurde gefunden, dass man einen neuen metallhaltigen Farbstoff erhält, wenn man auf den Farbstoff ia-us diazotierter 6-Nitro,- :
-amino -1-,phen.o1-4-sulio#säure und, ss-Naph- tli.o!l die Chromverbindung des Farbstoffes aus diazotierter 1-Amino-2--oxyn#a.pli#lialin-4- "ulf,osäure un.dss-Niaplithol einwirken lässt.
Das neue Produkt stellt ein schwarz liebes Pulver dar, löst sich in Wasser mit rotblauer, in<B>10</B> '/oiger Natronlaiuge mit vio,- letter und in konzentrierter S#eliwefelsäure mit sehwarzblauer Farbe und färbt Wolle und Seide in spbwärzlichblauen Tönen von vorzüglichen Echtheitseigenschaften, <I>Beispiel:
</I> <B>10</B> Teile,der Chromverbindung,des Farb stoffes aus diazotierter 1-Amin-o-2-oxynaph- tli-alin-4-sulfosäure und iss-Naplit'h.ol werden in<B>250</B> Teilen Wasser kochend gelöst.
Hier auf werden 2 Teile des Farbstoffes aus di- azotierter 6-Nitr-o-2-amino-l-pheno,1-4-sulfo- säur-- una #ss-Na#phtliol hinzugelöst, das Lö- sungsgemisoh mit Essigsäure schwach ange säuert und längere Zeit rückfliessend ge kocht. Der neue Farbstoff wird hernach in üblicher Weise gewonnen.
Additional patent to main paient no. <B> 130699. </B> Process for the production of a new metal-containing dye. It has been found that a new metal-containing dye is obtained if the dye ia-us diazotized 6-nitro, -:
-amino -1-, phen.o1-4-sulio # acid and, ss-naph- tli.o! l the chromium compound of the dye from diazotized 1-amino-2 - oxyn # a.pli # lialin-4- " ulf, oic acid and dss-niaplithol to act.
The new product is a black powder, dissolves in water with red-blue, in <B> 10 </B> '/ o sodium hydroxide solution with violet and in concentrated sulfuric acid with a black-blue color and dyes wool and silk in blackish blue tones with excellent fastness properties, <I> Example:
</I> <B> 10 </B> parts, the chromium compound, the dye from diazotized 1-amine-o-2-oxynaph- tli-aline-4-sulfonic acid and iss-Naplit'h.ol are in < B> 250 </B> parts of boiling water dissolved.
Here, 2 parts of the dyestuff from diacotized 6-nitr-o-2-amino-1-pheno, 1-4-sulfoic acid and sodium phthalol are dissolved, and the solution is mixed with acetic acid weakly acidified and refluxed for a long time. The new dye is then obtained in the usual way.
