EMI2.1
Erzeugt man den Farbstoff nach der Arbeitsweise der Patentschrift Nr. 62875 auf Baumwollgarn, so erhält man ein leuchtendes Rot von hervorragender Echtheit.
Beispiel 2.
Das gut mit Soda oder Ätznatron ausgekochte, gebleichte oder rohe Baumwollgarn wird bei etwa 40 imprägniert mit einer Lösung von Benzoyl-2. 3-aminonaphtol, deren Bereitung im Beispiel 1 beschrieben ist, scharf abgewunden und nach dem Erkalten in einem Färbebade von folgender Zusammensetzung gefärbt : 500 cm3 Diazolösung werden mit
40cm3Kupferchloridlösung40 Bé,
12 cm3 Chromsäurelösung 1 : 10 und
100 cm3 essigsaurer Tonerde 12"Be gemischt und kurz vor dem Färben
50 cm3 essigsaures Natrium l : 1 gelöst zugegeben.
Das Ganze wird auf 1 l eingestellt.
Diazolösung :
24 g Dianisidinbase werden mit
21 cm3 Salzsäure 20 Bé und
250 cm3 kochendem Wasser gelöst, abgekühlt,
200 9 Eis und
10 cm3 Salzsäure 200 Bd zugegeben und
16 9 Natriumnitrit gelöst in
50 cm3 Wasser unter gutem Rühren einfliessen lassen, worauf auf 1 l eingestellt wird.
EMI2.2
Man erhält so schöne rotstichig blaue Färbungen.
An Stelle von 2-Benzoylamino-3-naphtol können dessen Substitutionsprodukte, wie zum Beispiel Halogenbenzoylamino-3-naphtol oder 2-Nitrobenzoylamino-3-naphtol oder andere Azidylderivate des 2. 3-Aminonaphtols Verwendung finden, wie z. B. Azetylamino-3-naphtol, 3. 3'-Dioxy- -2.2'-dinaphtylharnstoff usw.

EMI2.1
If the dye is produced on cotton yarn according to the method of patent specification No. 62875, a bright red of excellent fastness is obtained.
Example 2.
The bleached or raw cotton yarn, well boiled with soda or caustic soda, is impregnated at around 40 with a solution of benzoyl-2. 3-aminonaphtol, the preparation of which is described in Example 1, is sharply wound and, after cooling, colored in a dye bath of the following composition: 500 cm3 of diazo solution are added
40cm3 copper chloride solution 40 Bé,
12 cm3 chromic acid solution 1:10 and
100 cm3 of acetic clay 12 "Be mixed and just before dyeing
50 cm3 of sodium acetate (1: 1) dissolved.
The whole is adjusted to 1 l.
Diazo solution:
24 g of dianisidine base are added
21 cm3 hydrochloric acid 20 Bé and
250 cm3 of boiling water dissolved, cooled,
200 9 ice cream and
10 cm3 hydrochloric acid 200 Bd are added and
16 9 sodium nitrite dissolved in
Allow 50 cm3 of water to flow in while stirring well, after which it is adjusted to 1 l.
EMI2.2
This gives beautiful, reddish-tinged blue colorations.
Instead of 2-benzoylamino-3-naphtol, its substitution products, such as, for example, halobenzoylamino-3-naphtol or 2-nitrobenzoylamino-3-naphtol or other azidyl derivatives of 2, 3-aminonaphthol, can be used, e.g. B. acetylamino-3-naphtol, 3. 3'-dioxy- -2.2'-dinaphtylurea, etc.
