Description

  

  <B>Zusatzpatent</B> zum Hauptpatent Nr. 181808.    Verfahren zur Herstellung eines     ehromierbaren    gelben     Azofarbstoifes.       Gegenstand des vorliegenden Zusatzpa  tentes ist ein Verfahren zur Herstellung eines       chromierbaren    gelben     Azofarbstoffes,    welches  darin besteht, dass man dianotierte     ortho-          Aminobenzoesäure    mit     1-(2"-Methyl-4'-phen-          oxy-3'.s    u     lfophenyl)-5-pyrazolon-3-carbonsäure-          äthylester    kuppelt.  



  <I>Beispiel:</I>  137 Gewichtsteile     ortho-Aminobenzoesäure     werden in üblicher Weise dianotiert und mit  einer     sodaalkalischen    Lösung von 418 Ge  wichtsteilen     1-(2"-Methyl-4'-phenoxy-3'-sulfo-          phenyl)-5        -pyrazolon        -3-carbonsäureäthylester     vereinigt. Nach beendeter Kupplung wird der       Farbstoff    abgesaugt und getrocknet.  



  Er stellt ein gelbes, in Wasser leicht lös  liches Pulver dar, das Wolle in gelben Tönen  färbt, die sich nach erfolgter Behandlung mit  chromabgebenden Mitteln, wie zum Beispiel       Kaliumbichromat    und Schwefelsäure, durch    gute Echtheitseigenschaften, insbesondere sehr  gute     Walkechtheit    auszeichnen.



  <B> Additional patent </B> to main patent no. 181808. Process for the production of an honorable yellow azo dye. The subject of the present additional patent is a process for the production of a chromable yellow azo dye, which consists in that dianotated ortho-aminobenzoic acid with 1- (2 "-methyl-4'-phenoxy-3'.sulfophenyl) -5- pyrazolone-3-carboxylic acid ethyl ester couples.



  <I> Example: </I> 137 parts by weight of ortho-aminobenzoic acid are dianotized in the usual way and mixed with a soda-alkaline solution of 418 parts by weight of 1- (2 "-methyl-4'-phenoxy-3'-sulfophenyl) -5 -pyrazolone-3-carboxylic acid ethyl ester combined After the coupling, the dye is filtered off with suction and dried.



  It is a yellow, easily soluble in water powder that dyes wool in yellow tones which, after treatment with chromium-releasing agents, such as potassium dichromate and sulfuric acid, are characterized by good fastness properties, in particular very good milled fastness.
