Description

  

  Zusatzpatent zum Hauptpatent     Nr.   <B>127259.</B>    Verfahren zur Herstellung eines neuen Farbstoffes.    Es wurde gefunden,     dass    man einen neuen  Farbstoff erhält, wenn man     diazotierte        4-          Benzoylamino-2-amino-l-benzolsulfosäure    mit       1-(3'-Chlor)-phenyl-3-methyl-5-pyrazolon    kup  pelt. Der so erhaltene Farbstoff bildet ein  gelbes Pulver. Er färbt Wolle aus schwefel  saurem Bade in sehr gleichmässigen, gelben  Tönen. Die Färbungen sind sehr gut licht-,       wasser-,    wasch- und     alkaliecht    und halten  der sauren Walke stand. Er ist auch zum  Färben der gewöhnlichen und der chargierten  Seide geeignet.

      <I>Beispiel:</I>    <B>20,9</B> Teile     1-(3'-Chlor)-pheiiyl-3-methyl-6-          pyrazolon    werden in<B>150</B> Teilen Wasser mit  20 Teilen     calcinierter    Soda und der nötigen  Menge Natronlauge gelöst, mit Eis gekühlt       und    hierauf mit der     Diazoverbindung    aus<B>29,2</B>  Teilen     4-Benzylamino-2-amino-l-benzolsulfo-          säure    versetzt. Der sich bildende Farbstoff    scheidet sich teilweise aus. Durch Zusatz von  Kochsalz wird die Fällung vervollständigt,  dann wird möglichst neutral gestellt,     filtriert     und getrocknet.



  Additional patent to main patent no. <B> 127259. </B> Process for the production of a new dye. It has been found that a new dye is obtained if diazotized 4-benzoylamino-2-amino-1-benzenesulfonic acid is coupled with 1- (3'-chloro) -phenyl-3-methyl-5-pyrazolone. The dye thus obtained forms a yellow powder. He dyes wool from a sulphurous acid bath in very even, yellow tones. The dyeings are very light, water, wash and alkali-fast and withstand acidic milled wool. It is also suitable for dyeing ordinary and charged silk.

      <I> Example: </I> <B> 20.9 </B> parts of 1- (3'-chloro) -pheiiyl-3-methyl-6-pyrazolone are used in <B> 150 </B> parts of water dissolved with 20 parts of calcined soda and the necessary amount of sodium hydroxide solution, cooled with ice and then mixed with the diazo compound of 29.2 parts of 4-benzylamino-2-amino-1-benzenesulphonic acid. The dye that forms is partially separated out. The precipitation is completed by adding sodium chloride, then it is made as neutral as possible, filtered and dried.

Claim: Process for the preparation of a new dye, characterized in that diazotized 4-benzoylamino-2-amino-1-benzenesulfonic acid is mixed with 1- (3'-chloro) -phenyl-3-methyl - 5-pyrazolone couples. The dye thus obtained forms a yellow powder. He dyes wool from sulfuric acid bath in very even, yellow tones. The dyeings are very light, water, wash and alkali-fast and withstand acidic milled wool. It is also suitable for dyeing ordinary and charred silk.
