Es <SEP> wurde <SEP> gefunden, <SEP> dass <SEP> man <SEP> einen <SEP> gut
<tb> ziehenden <SEP> und <SEP> gut <SEP> löslichen <SEP> substantiven
<tb> Farbstoff <SEP> erhält, <SEP> wenn <SEP> man <SEP> die <SEP> Tetrazover bindung <SEP> der <SEP> 4.4'*-Diaminodil)henyl-3.3'-di carbonsäure <SEP> einerseits <SEP> mit <SEP> Phonyl-ss-,laphtyl amin <SEP> und <SEP> anderseits <SEP> mit <SEP> 1-Amino-8-oxyna.-ph taliii-4-sulfosäure <SEP> kombiniert.
<tb>
<I>Beispiel:</I>
<tb> <B>272</B> <SEP> Gewichtsteile <SEP> 4.4' -Diamiiiodipheiiyl <B>3</B> <SEP> .3'-diearbonsäure <SEP> werden <SEP> in <SEP> Eisessig <SEP> mit
<tb> Nitrit <SEP> und <SEP> Salzsäure <SEP> tetrazotiert <SEP> und <SEP> dazu
<tb> eine <SEP> Lösung <SEP> von <SEP> <B>219</B> <SEP> Gewichtsteilen <SEP> Phenyl ss-naphtylamin <SEP> in <SEP> Eisessig <SEP> gegeben. <SEP> Nach
<tb> Beendigung <SEP> der <SEP> Bildung <SEP> des <SEP> Zwisehenpro duktes <SEP> wird <SEP> dasselbe <SEP> abgesaugt <SEP> und <SEP> in <SEP> eine
<tb> sodaalkalische <SEP> Lösung <SEP> vön <SEP> <B>239</B> <SEP> Gewichts teilen <SEP> 1-A.mino-8-oxyna-phi-i%lin-4-siilfosii-uire
<tb> unter <SEP> Rühren <SEP> eingetragen.
<SEP> Der <SEP> auf <SEP> diese
<tb> Weise <SEP> erhaltene <SEP> Tetrazofarbstoff <SEP> wird <SEP> in <SEP> be hannter <SEP> Weise <SEP> aufgearbeitet <SEP> und <SEP> umgelöst Er stellt ein schwarzes Pulver dar, das ungebeizte Baumwolle violett anfärbt. Beim Naellkupfern entsteht ein -waschechtes und licUtechtes Blau.

<SEP> was found <SEP>, <SEP> that <SEP> man <SEP> a <SEP> good
<tb> drawing <SEP> and <SEP> well <SEP> soluble <SEP> nouns
<tb> Dye <SEP> is obtained, <SEP> if <SEP> one <SEP> the <SEP> tetrazo compound <SEP> of the <SEP> 4.4 '* - diaminodil) henyl-3.3'-dicarboxylic acid <SEP> on the one hand <SEP> combined with <SEP> phonyl-ss-, laphthyl amine <SEP> and <SEP> on the other hand <SEP> with <SEP> 1-amino-8-oxyna.-ph taliii-4-sulfonic acid <SEP>.
<tb>
<I> Example: </I>
<tb> <B> 272 </B> <SEP> Parts by weight <SEP> 4.4'-diamiiiodipheiiyl <B> 3 </B> <SEP> .3'-diacid <SEP> become <SEP> in <SEP> glacial acetic acid <SEP> with
<tb> nitrite <SEP> and <SEP> hydrochloric acid <SEP> tetrazotized <SEP> and <SEP> in addition
<tb> a <SEP> solution <SEP> of <SEP> <B> 219 </B> <SEP> parts by weight <SEP> phenyl ss-naphtylamine <SEP> in <SEP> glacial acetic acid <SEP>. <SEP> After
<tb> Completion <SEP> of <SEP> formation <SEP> of the <SEP> joint product <SEP>, <SEP> the same <SEP> is extracted <SEP> and <SEP> in <SEP> one
<tb> soda-alkaline <SEP> solution <SEP> of <SEP> <B> 239 </B> <SEP> divide weight <SEP> 1-A.mino-8-oxyna-phi-i% lin-4-siilfosii -uire
<tb> entered under <SEP> stirring <SEP>.
<SEP> The <SEP> on <SEP> this
<tb> <SEP> obtained <SEP> tetrazo dye <SEP> is <SEP> processed <SEP> in the known <SEP> manner <SEP> <SEP> and <SEP> redissolved It is a black powder, the unpickled one Dyes cotton purple. With nail copper, the result is a washfast and lightfast blue.
