PATENTAMT.PATENT OFFICE.
In der Patentschrift 114976, Zusatz zum Patente 91855, ist unter anderem ein Verfahren zur Darstellung eines schwarzen, durch Lichtechtheit ausgezeichneten Azofarbstoffe, welches in der Combination der α, a4-Amidonaphtol-ct2-monosulfosa'ure mit Diazosulfanilsäure einerseits und Diazoazobenzol andererseits besteht, beschrieben, und finden sich die näheren Angaben über die Darstellung des Farbstoffs im Beispiel 3.In patent specification 114976, addendum to patent 91855, there is, among other things, a process for the preparation of a black azo dyes characterized by lightfastness, which consists in the combination of α, a 4 -amidonaphthol-ct 2 -monosulfosa'ure with diazosulfanilic acid on the one hand and diazoazobenzene on the other hand , and the details of the preparation of the dye can be found in Example 3.
Es hat sich nun ergeben, dafs, wenn in diesem Verfahren die letztere Diazoverbindung durch die Diazoverbindung des o-Amidoazotoluols ersetzt wird,, man einen Farbstoff erhält, welcher gleichfalls von grofser Lichtechtheit ist, zugleich aber eine noch hervorragendere Waschechtheit besitzt und sich überdies, durch die Gleichmäfsigkeit auszeichnet, mit welcher er Wolle und Seide in gemischten Geweben anfärbt.It has now been found that if in this process the latter diazo compound is replaced by the diazo compound of o-amidoazotoluene, a dye is obtained which is also of great lightfastness, but at the same time an even more outstanding one Has washfastness and, moreover, is characterized by its uniformity which he dyes wool and silk in mixed fabrics.
Die Darstellung geschieht nach den in Beispiel 3 der Patentschrift 114976 beschriebenen Verfahren unter Ersatz der dort angegebenen Menge von Amidoazobenzol durch 22,5 kg Amidoazotoluol.The representation is carried out according to that described in Example 3 of Patent 114976 Process in which the amount of amidoazobenzene specified there is replaced by 22.5 kg Amidoazotoluene.
Die Eigenschaften des Farbstoffs sind aus folgender Tabelle ersichtlich:The properties of the dye can be seen from the following table:
