Verfahren zur Darstellung von gelbroten bis blauroten Disazofarbstoffen.
In der Stammpatontschrift Nr. 41782 und dessen Zusätzen ist ein Verfahren zur Darstellung substantiver gelbroter und blauroter Farbstoffe beschrieben.
Es wurde nun gefunden, dass ebenso wie die Naphtolderivate die Pyrazolonn bezw. deren Sulfo- und Carbonsäuren als Endkomponente bei der Kupplung mit der Verbindung Diazoverbindung p-Aminobenzoyl 2. 5. 7-aminonaphtolsulfosäure wertvolle substantive Farbstoffe liefern. Die Pyrazolonprodukte sind gelbstichiger als die nach der Patentschrift Nr. 41782 oder deren Zusätzen erhaltenen Farbstoffe. Sie liefern auf ungeheizten Baum- wolle golbrote bis orange Töne, welche eine gute Licht- und Waschechtheit besitzen.
Beispiel.
Der Farbstoff aus 9'3 kg Anilin mit p-Aminobenzoyl-2. 5. 7-aminonaphtolsulfosäure (erhalten nach der deutschen Patentschrift Nr. 151017) wird gemäss den Angaben der Patentschrift Nr. 41782 in seine Diazoverbindung übergeführt. Dieselbe lässt man bei

Process for the preparation of yellow-red to blue-red disazo dyes.
In the parent patronage No. 41782 and its additions, a method for the representation of substantive yellow-red and blue-red dyes is described.
It has now been found that, like the naphthol derivatives, the pyrazolone respectively. their sulfo- and carboxylic acids as end components in the coupling with the compound diazo compound p-aminobenzoyl 2.5. The pyrazolone products are more yellowish than the dyes obtained according to patent specification No. 41782 or their additives. On unheated cotton, they deliver golden-red to orange tones, which are lightfast and washfast.
Example.
The dye from 9'3 kg of aniline with p-aminobenzoyl-2. 5. 7-aminonaphtholsulfonic acid (obtained according to German Patent No. 151017) is converted into its diazo compound according to the information in Patent No. 41782. One leaves the same
