Description

  

  Zusatzpatent zum Hauptpatent     Nr.   <B>175028.</B>    Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden,     dass    man einen neuen Farbstoff     ei-]hält,    welcher der Formel  
EMI0001.0005     
    entspricht, wenn man     diazotiertes        4-(2-          Methyl)-plieiioxyacetylamirio-2.5-diäthoxy-   <B>1</B>     -          aminobenzol    mit dem     3-Ohloranilid    der 2.     3-          Oxynaphthoesäure    kuppelt.  



  Der neue Farbstoff bildet ein dunkel  blaues Pulver. Auf geeigneten Substraten,  wie zum Beispiel pflanzlichen Fasern, herge  stellt, färbt er diese in echten blauen Tönen.  <I>Beispiel:</I>  84,4 Teile     4-(2'-Methyl)-phenoxyacetyl-          amino-2.        5-diäthoxy-l-aminobenzol    werden    wie üblich     diazotiert    und in eine Lösung  von<B>29,7</B> Teilen     des'3-Chloranilids    der     2.3-          Oxynaphthoesäure,        60        Teilen        30        %iger        Na-          tronlauge,

     <B>30</B> Teilen Soda und 2000 Teilen  Wasser     einget   <B>'</B> ragen. Der gebildete Farbstoff  fällt sofort aus. Der dunkelblaue Nieder  schlag wird filtriert und getrocknet.



  Additional patent to main patent no. <B> 175028. </B> Process for the production of a new azo dye. It has been found that one holds a new dye which has the formula
EMI0001.0005
    corresponds if one couples diazotized 4- (2-methyl) -plieiioxyacetylamirio-2.5-diethoxy- <B> 1 </B> - aminobenzene with the 3-chloroanilide of the 2,3-oxynaphthoic acid.



  The new dye forms a dark blue powder. On suitable substrates, such as vegetable fibers, he dyes them in real blue tones. <I> Example: </I> 84.4 parts 4- (2'-methyl) -phenoxyacetyl-amino-2. 5-diethoxy-l-aminobenzene are diazotized as usual and dissolved in a solution of 29.7 parts of the 3-chloroanilide of 2,3-oxynaphthoic acid, 60 parts of 30% strength sodium hydroxide solution,

     <B> 30 </B> parts of soda and 2000 parts of <B> '</B> water stick out. The dye formed precipitates immediately. The dark blue precipitate is filtered and dried.

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen Farbstoffes, welcher der Formel EMI0002.0001 entspricht, dadurch gekennzeichnet, dass man diazotiertes 4-(2'-Methyl)-phenoxyacetylaniirio- 2. 5-diäthoxy-l-aminobenzol mit dem S-Chlor- anilid der 2.3-Oxyi)aphthoesätii-e, kuppelt. Der neue Farbstoff bildet ein dunkel blaues Pulver. Auf geeigneten Substraten, wie zum Beispiel pflanzlichen Fasern, her gestellt, färbt er diese in echten blauen Tönen. PATENT CLAIM: Process for the production of a new dye, which of the formula EMI0002.0001 corresponds, characterized in that diazotized 4- (2'-methyl) -phenoxyacetylaniirio- 2. 5-diethoxy-l-aminobenzene with the S-chloroanilide of 2.3-Oxyi) aphthoesätii-e, coupled. The new dye forms a dark blue powder. Produced on suitable substrates, such as vegetable fibers, he dyes them in real blue tones.
