Description
Zusatzpatent zum Hauptpatent Nr. 193080. Verfahren zur Herstellung eines neuen Farbstoffes. Es wurde gefunden, dass man einen Farb stoff erhält, wenn man dianotierten 4-Chlor- 2-aminodiphenyläther mit 5-Oxy-l-phenyl-4'- methylazimidobenzol vereinigt.
Der neue Farbstoff bildet ein scharlach rotes, in Wasser unlösliches Pulver. Auf einem geeigneten Substrat hergestellt, färbt er dieses scharlachrot.
<I>Beispiel:</I> <B>21,9</B> Teile 4-Chlor-2-aminodiphenyläther werden wie üblich dianotiert und einer alka lischen Lösung von 22,5 Teilen 5-Oxy-l-phenyl- 4'-methylazimidobenzol langsam zugegeben. Der gebildete Farbstoff fällt sofort als schar- lachrot gefärbter Niederschlag aus. Er wird filtriert und getrocknet.
Additional patent to main patent No. 193080. Process for the production of a new dye. It has been found that a dye is obtained when dianotized 4-chloro-2-aminodiphenyl ether is combined with 5-oxy-1-phenyl-4'-methylazimidobenzene.
The new dye forms a scarlet red powder that is insoluble in water. Produced on a suitable substrate, he colors it scarlet red.
<I> Example: </I> <B> 21.9 </B> parts of 4-chloro-2-aminodiphenyl ether are dianotized as usual and an alkaline solution of 22.5 parts of 5-oxy-1-phenyl-4 '-methylazimidobenzene added slowly. The dye formed precipitates immediately as a sharp red colored precipitate. It is filtered and dried.
