Description

  

  Verfahren zur Herstellung eines neuen     Azofarbstoffes.       Es wurde gefunden, dass man einen neuen       Azofarbstoff    erhält, wenn man dianotiertes       3-Amino-phthalsäure-N-iso-amyl-imid    mit dem       2,3-Oxynaphthoesäure-ss-naphthylamid    ver  einigt.  



  Der neue     Farbstoff    bildet ein scharlach  rotes, in Wasser unlösliches Pulver. Auf ge  eigneten Substraten, wie z. B. Baumwolle,  hergestellt, färbt er diese in echten scharlach  roten Tönen.  



  <I>Beispiel:</I>  23,2 Teile des     3-Amino-phthalsäure-N-          iso-amyl-imids    werden wie üblich dianotiert  und in eine Lösung von 31,3 Teilen 2,3  Oxynaphthoesäure-ss-naphthylamid, 40 Teilen  30     0%iger        Natriumhydrogydlösung,    15 Teilen  Soda in<B>1000</B> Teilen Wasser eingetragen. Der    gebildete Farbstoff fällt sofort aus. Der  scharlachrote Niederschlag wird filtriert und  getrocknet.



  Process for the production of a new azo dye. It has been found that a new azo dye is obtained if dianotated 3-amino-phthalic acid-N-iso-amyl-imide is combined with 2,3-oxynaphthoic acid-s-naphthylamide.



  The new dye forms a scarlet red powder that is insoluble in water. On ge suitable substrates such. B. Cotton, he dyes them in real scarlet red tones.



  <I> Example: </I> 23.2 parts of 3-amino-phthalic acid-N-iso-amyl-imide are dianotized as usual and poured into a solution of 31.3 parts of 2,3-oxynaphthoic acid-s-naphthylamide, 40 Parts of 30% strength sodium hydrogen solution, 15 parts of soda in <B> 1000 </B> parts of water are added. The dye formed precipitates immediately. The scarlet precipitate is filtered and dried.

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen Azofarbstoffes, dadurch gekennzeichnet, dass man dianotiertes 3-Amino-phtbalsäure-I\T-iso- amyl-imid mit dem 2,3-Oxynaphthoesäure-ss- naphthylamid vereinigt. Der neue Farbstoff bildet ein scharlach rotes Pulver, das in Wasser unlöslich ist. Auf geeigneten Substraten, wie z. B. Baum wolle, hergestellt, färbt er diese in echten scharlachroten Tönen. PATENT CLAIM: Process for the production of a new azo dye, characterized in that dianotated 3-amino-phtbalic acid-I \ T-iso-amyl-imide is combined with 2,3-oxynaphthoic acid-ss-naphthylamide. The new dye forms a scarlet red powder that is insoluble in water. On suitable substrates, such as. B. tree wool, he dyes them in real scarlet shades.
