    <I> Example: </I>
<tb> 100 <SEP> 1; <SEP> 3,7-1) ibroin-5-ainino-8-oiy-1, l-iiapii tliocliinoniniid- (1) <SEP> become <SEP> with <SEP> 35 <SEP> g <SEP> o- Aniido 1> lienol <SEP> in <SEP> 250 <SEP> g <SEP> glacial acetic acid <SEP> in <SEP> presence <SEP> of
<tb> 50 <SEP> g <SEP> Natriuniaeetat <SEP> during <SEP> 11.i <SEP> hours <SEP> on

PATENTANSPRUCH: Verfahren zur Herstellung eines neuen Kondensationsproduktes, dadureb gekenn- zeiehnet, dass man das nach dem Verfahren gemäss Patentansprueh der Patentschrift Nr.251616 erhältliche 3,7-Dibrom-5-amino-8- oxy-1,.l-napht.hochinonimid-(1) mit o-Amido- phenol in Eisessig in Gegenwart von Nat.riuni- aeetat kondensiert. PATENT CLAIM: Process for the production of a new condensation product, dadureb marked that the 3,7-dibromo-5-amino-8-oxy-1, .l-naphth.hochinonimid obtainable by the process according to patent claim of patent specification No. 251616 - (1) condensed with o-amidophenol in glacial acetic acid in the presence of Nat.riuni- aeetat. Die nette Verbindung stellt ein schwarz blaues Produkt dar, welehes sich in Alkohol roi-stiehi- blau, in Schwefelsäure grün löst. Die schwefelsaure Lösung färbt sieh auf Zu satz von Formaldehyd blaugrün, auf Zusatz von Borsäure naeli Erwärmen ebenfalls blau grün. DDie neue Verbindung färbt -Icetatseide in graublauen Tönen. The nice connection is a black-blue product, which dissolves in alcohol roi-stiehi- blue, in sulfuric acid green. The sulfuric acid solution turns blue-green on the addition of formaldehyde, and blue-green on the addition of boric acid after heating. The new compound dyes acetate silk in gray-blue tones.
