Description

Verfahren zur Herstellung von wasserunlöslichen Azofarbstoffen Es wurde gefunden, daß man zu wertvollen wasserunlöslichen Azofarbstoffen gelangt, wenn man die Diazoverbindungen aus i-Amino-4-cyanbenzolen, die in 2-und 5-Stellung substituiert sind, mit o-Oxyarylcarbonsäurearylamiden oder ß-Ketocarbonsäurearylamiden für sich oder auf einer Grundlage kuppelt, wobei die Farbstoffkomponenten keine löslich machenden Gruppen, wie Sfilfonsäure- oder Carbonsäuregruppen, enthalten sollen.Process for the production of water-insoluble azo dyes Es it was found that valuable water-insoluble azo dyes can be obtained, if the diazo compounds from i-amino-4-cyanobenzenes, which are in the 2- and 5-positions are substituted with o-Oxyarylcarbonsäurearylamiden or ß-Ketocarbonsäurearylamiden by itself or on a coupling basis, the dye components none solubilizing groups, such as sulfonic acid or carboxylic acid groups should.

In Substanz hergestellt können die neuen Farbstoffe zur Bereitung von wertvollen Pigmentfarbstoffen dienen; sie sind aber auch besonders zur Herstellung von unlöslichen Farbstoffen auf der Faser, auf natürlicher oder umgefällter Cellulose oder auch auf tierischen Fasern, nach dem Verfahren zur Herstellung von Eisfarben oder nach einem der üblichen Druckverfahren, z. B. im Direktdruck oder auch nach dem ;bekannten Druckverfahren unter Verwendung von Nitrosaminen oder Diazoaminoverbindungen, geeignet.The new dyes can be produced in substance for preparation serve of valuable pigment dyes; but they are also special for manufacture of insoluble dyes on the fiber, on natural or reprecipitated cellulose or on animal fibers, using the process for the production of ice colors or by one of the usual printing processes, e.g. B. in direct printing or after the known printing process using nitrosamines or diazoamino compounds, suitable.

Vor vergleichbaren, aus der Patentschrift 510.I79 (entsprechend der amerikanischen Patentschrift i 759 259) bekannten wasserunlöslichen Azofarbstoffen zeichnen sich die nach dem vorliegenden Verfahren erhältlichen wasserunlöslichen Azofarbstoffe durch ihre bessere Lichtechtheit aus. Beispiel i Gut ausgekochtes, getrocknetes Baumwollgarn wird mit einer Lösung von q. g i-(2', 3'-Oxynaphthoylamino) - naphthalin, 1o ccm Natronlauge von 3.4° Be und io ccm Türkischrotöl (5oprozentig) im Liter imprägniert, gut abgewunden und mit einer schwach essigsauren Entwicklungslösung, die i,82 g i-Amino-3-methoxy-6-chlor-d.-cyanbenzol als Diazoverbindung im Liter enthält, entwickelt, gespült und geseift.Before comparable, from patent specification 510.179 (corresponding to the American patent 1,759,259) known water-insoluble azo dyes the water-insoluble ones obtainable by the present process stand out Azo dyes are characterized by their better lightfastness. Example i Well-cooked, dried cotton yarn is mixed with a solution of q. g i- (2 ', 3'-oxynaphthoylamino) - naphthalene, 1o ccm sodium hydroxide solution of 3.4 ° Be and 10 ccm Turkish red oil (5%) impregnated in the liter, well wound and with a weakly acetic acid developing solution, the 1.82 g of i-amino-3-methoxy-6-chloro-d.-cyanobenzene as a diazo compound per liter contains, developed, rinsed and soaped.

Man erhält eine blaurote Färbung von sehr guter Lichtechtheit.A blue-red dyeing of very good lightfastness is obtained.

Verwendet man 2, 3-Oxynaphthoylaminobenzol als Azokomponente, so erhält man eine gelbrote Färbung von ebenfalls sehr guter Lichtbeständigkeit.. Beispiel Entschlichtete und gebleichte Baumwollstückware wird auf einem Foulard mit einer Lösung geklotzt, die im Liter 15 g 2, 3-Oxynaphthoylaminobenzol, 22,5 ccm Natronlauge von 3.I° Be und 22,5 ccm Türkischrotöl (5oprozentig) enthält: Der imprägnierte und getrocknete Stoff wird dann durch eine Entwicklungslösung geführt, welche die Diazoverbindung aus 12 g i-Ainino-2, 5-dichlor- 4-cy anbenzol im Liter enthält und schwach essigsauer gestellt ist. Nach kurzem Luftgang wird der Stoff sodann mehrmals mit kaltem Wasser gespült und schließlich in der üblichen Weise geseift, gespült und getrocknet.If 2,3-oxynaphthoylaminobenzene is used as the azo component, the result is a yellow-red coloration which is also very lightfast . 5 cc sodium hydroxide solution of 3.I ° Be and 22.5 cc Turkish red oil (5%) contains: The impregnated and dried substance is then passed through a developing solution, which is the diazo compound from 12 g of i-ainino-2, 5-dichloro-4- contains cy anbenzene per liter and is slightly acidic in acetic acid. After a short ventilation, the fabric is then rinsed several times with cold water and finally soaped, rinsed and dried in the usual way.

Man erhält so eine gelbrote Färbung von sehr guter Lichtechtheit. Beispiel 3 Kunstseidenmischgewebe (Baumwolle mit Viscosekunstseide) wird in bekannter Weise in einer ätzalkalischen Lösung von io g 4,4 -Diacetoacetylamino-3, 3'-dimethyl:diphenyl im Liter bei 7o bis So' C foulardmäßig grundiert, zwischengetrocknet und foulardmäßig entwickelt mit einer Lösung, die 8,5 g i-Amino-3-methyl-6-chlor-4-cyanbenzol als Diazoverbindung und 20 ccm 50prozentige Essigsäure im Liter enthält. Nach dem Spülen wird kurz bei 7o bis 75° C mit einer Lösung von 5 g Marsei-ller Seife im Liter nachbehandelt, gut gespült und getrocknet.A yellow-red dyeing of very good lightfastness is obtained in this way. Example 3 Artificial silk blend fabric (cotton with viscose artificial silk) is known in Way in a caustic solution of 10 g 4,4-diacetoacetylamino-3, 3'-dimethyl: diphenyl per liter at 7o to Sun 'C, primed in a pad-like manner, dried in between and pad-like developed with a solution containing 8.5 g of i-amino-3-methyl-6-chloro-4-cyanobenzene as Contains diazo compound and 20 ccm of 50 percent acetic acid per liter. After rinsing is treated briefly at 70 to 75 ° C with a solution of 5 g of Marseilles soap per liter, rinsed well and dried.

Die Färbung wird darauf mit einer Ätze, bestehend aus 200g Natriumformaldehydsulfoxylat, 40 g i-benzylaminobenzol-4-sulfonsaures Natrium, 30 g Kaliumcarbonat, 40 g Anthrachinonteig (30prozentig), 50o g neutrale Stärketragantv erdickung und 150 g Wasser, bedruckt, getrocknet, gedämpft, sodann heiß gespült, kochend geseift, wiederum gespült und getrocknet.The color is then etched with 200 g of sodium formaldehyde sulfoxylate, 40 g of i-benzylaminobenzene-4-sulfonic acid, 30 g of potassium carbonate, 40 g of anthraquinone dough (30 percent), 50 g of neutral starch thickener and 150 g of water, printed, dried, steamed , then rinsed with hot water, soaped at the boil, rinsed again and dried.

Man erhält so einen reinweißen Ätzeffekt auf rotstichiggelbem Grunde.This gives a pure white etching effect on a reddish-yellow background.

Beispiel 4 Entschlichtete und gebleichte Baumwollstückware wird mit einer, wie üblich, hergestellten Klotzlösung aus 12 g 2, 3-Oxynaphthoylaminobenzol im Liter foulardmäßig grundiert und getrocknet. Die Ware wird darauf mit einer Rotreserve von folgender Zusammensetzung bedruckt: 8 g i-Amino-3-methyl-6-chlor-4-cyanbenzol in Form einer stabilisierten Diazoniumverbindung, 310 g Wasser, i 50 g Aluminiumsulfatlösung (i : i ) und 500 g neutrale Stärketragantverdickung im Kilogramm Druckfarbe.Example 4 Desized and bleached cotton piece goods are primed with a padding solution prepared as usual from 12 g 2,3-oxynaphthoylaminobenzene per liter and dried. The goods are then printed with a red reserve of the following composition: 8 g of i-amino-3-methyl-6-chloro-4-cyanobenzene in the form of a stabilized diazonium compound, 310 g of water, i 50 g of aluminum sulfate solution (i: i) and 500 g neutral starch thickening per kilogram of printing ink.

Nach dem Trocknen wird mit einer Lösung entwickelt, die 9 g 4-Amino-4 -methoxydiphenylamin in Form des Diazoniumchlorids im Liter sowie Magnesiumsulfat enthält. Nach kurzem Luftgang geht der Stoff durch ein 5o° C warmes Bad, das mit 15 ccm einer Bisulfitlösung von 38° Be im Liter versetzt worden ist. Nach gründlichem heißem und kaltem Spülen wird kurz kochend geseift, gespült, wiederum geseift, gespült und getrocknet.After drying, it is developed with a solution containing 9 g of 4-amino-4 -methoxydiphenylamine in the form of diazonium chloride per liter and magnesium sulfate contains. After a short breather, the fabric goes through a 50 ° C warm bath that goes with it 15 ccm of a bisulfite solution of 38 ° Be per liter has been added. After thorough hot and cold rinsing is briefly soaped at the boil, rinsed, again soaped, rinsed and dried.

Man erhält einen gelbstichigroten Effekt auf blauem Grunde. Beispiel 5 3 9 i-(2', 3'-Oxynaphthoylamino)-2-methyl-4-chlorbenzol werden mit 4.5 ccm Natronlauge von 34° Be und 3 ccm Türkischrotöl (50prozentig) unter Zusatz eines der üblichen Schutzmittel für Seide, z. B. von 1,5 g gereinigter Sulfitcelluloseablauge in Pulverform, zu i 1 Klotzlösung gelöst.A yellowish-tinged red effect is obtained on a blue background. Example 5 3 9 i- (2 ', 3'-Oxynaphthoylamino) -2-methyl-4-chlorobenzene are mixed with 4.5 cc sodium hydroxide solution at 34 ° Be and 3 cc Turkish red oil (50 percent) with the addition of one of the usual protective agents for silk, e.g. B. 1.5 g of purified sulfite cellulose waste liquor in powder form, dissolved to i 1 pad solution.

Entbastete Chappeseide wird in dieser Lösung im Flottenverhältnis i :3o grundiert, abgequetscht und sodann in einer mit Natriumacetat bis zur Kongoneutralität versetzten Lösung des sauren Diazoniumsulfates aus 2,2g i-Amino-3-methoxy-6-trifluormethyl-4-cyanbenzol im Liter unter Zusatz von etwas Essigsäure entwickelt. Nach dem Spülen, Absäuern und heißen Seifen erhält man eine gelbrote Färbung von sehr guter Lichtechtheit.Debaffed chape silk is used in this solution in the liquor ratio i: 3o primed, squeezed and then in one with sodium acetate until Congo neutral added solution of the acidic diazonium sulfate from 2.2 g of i-amino-3-methoxy-6-trifluoromethyl-4-cyanobenzene Developed in the liter with the addition of a little acetic acid. After rinsing, acidifying and hot soaps, a yellow-red coloration of very good lightfastness is obtained.

Beispiel 6 Entschlichtete und gebleichte Baumwollstückware wird mit nachstehender Paste bedruckt: 33 g 3-Methyl-6-chlor-4-cyanbenzoli-nitrosaminkalium (wäßrige Paste mit einem Reingehalt von 44,9 °%o Base, enthaltend 4,2 °/o Ätzkali), 21 g 2, 3-Oxynaphthoylaminobenzol, 3o g Natronlauge von 34° Be, i 5 g Türkischrotöl (50prozentig) und 159 Sprit werden mit Sog Chromatlösung angeteigt, finit 336g warmem Wasser gelöst und mit 5oog neutraler Stärketragantverdickung auf i kg Druckfarbe eingestellt.Example 6 Desized and bleached cotton piece goods are used with printed with the following paste: 33 g of 3-methyl-6-chloro-4-cyanobenzolino-nitrosamine potassium (aqueous paste with a purity of 44.9% o base, containing 4.2% caustic potash), 21 g of 2,3-oxynaphthoylaminobenzene, 30 g of caustic soda solution of 34 ° Be, i 5 g of Turkish red oil (50 percent) and 159 fuel are made into a paste with suction chromate solution, finite 336g warm Dissolved water and with 50 og neutral starch carrier thickening on 1 kg of printing ink set.

Nach dem Trocknen wird der bedruckte Stoff 3 Minuten feucht gedämpft oder über Nacht verhängt und anschließend bei So bis 9o° C durch ein Bad genommen, das 2o g 50prozentige Essigsäure im Liter enthält, gespült und geseift.After drying, the printed material is dampened for 3 minutes or imposed overnight and then taken in a bath at Sun to 9o ° C, which contains 20 g of 50 percent acetic acid per liter, rinsed and soaped.

Man erhält einen gelbstichigroten Druck von sehr guter Lichtechtheit.A yellow-tinged red print of very good lightfastness is obtained.

Bei sinngemäßem Ersatz von 2, 3-Oxynaphthoylaminobenzol durch 4, 4'-Diacetoacetylamino-3, 3'-dimethyldiphenyl als Azolcomponente gelangt man zu einem rotstichigen Gelbdruck, der ebenfalls eine sehr gute Lichtechtheit aufweist.If 2, 3-oxynaphthoylaminobenzene is replaced by 4, 4'-diacetoacetylamino-3, 3'-dimethyldiphenyl as azole component leads to a reddish yellow print, which also has very good lightfastness.

Man gelangt gleichfalls zu echten Drucken, wenn man an Stelle des Nitrosamins eine geeignete Diazoaminoverbindung aus i-Amino-3-methyl-6-chlOr-4-cyanbenzol 'in bekannter Weise verwendet.You can also get real prints if you replace the Nitrosamine a suitable diazoamino compound from i-amino-3-methyl-6-chloro-4-cyanobenzene 'used in a known manner.

Beispiel ? 16,7 Gewichtsteile i-Amino-3-inethyl-6-chlor-4-cyanbenzol werden in üblicher Weise dianotiert, und die Diazolösung wird mit einer Lösung von 45,g Gewichtsteilen 1-(2', 3'-Oxynaphthoylamino) -2-methoxv-5-brombenzol in verdünnter Natronlauge, die mit einer zur Bindung der überschüssigen Mineralsäure hinreichenden Menge Natriumacetat sowie mit Türkischrotöl versetzt ist, vereinigt. Der ausgeschiedene Azofarbstoff wird abfiltriert und gut ausgewaschen. In üblicher Weise, vorteilhaft in Form einer Paste, mit Substraten verarbeitet liefert er einen roten Lack von hoher Lichtechtheit. Beispiel 8 Vorgebleichte Leinenstückware wird foulardmällig grundiert mit einer Lösung, die 20 g i- (2'-Oxycarbazol-3'-carboylamino)-4-chlorbenzol, 2o ccm Natronlauge von 341 Be und 30 ccm Türkischrotöl (5oprozentig) im Liter enthält, gut abgequetscht und zwischengetrocknet. Danach wird auf einem Foulard entwickelt in einer Lösung. die3,4g i-Amino-2,5-dimethoxy-4-cyanbenzol in Form :des Diazoniumchlorids sowie Aluminiumsulfat enthält. Nach dem Entwickeln wird gespült, geseift, wiederum gespült und getrocknet.Example ? 16.7 parts by weight of i-amino-3-ynethyl-6-chloro-4-cyanobenzene are dianotized in the usual manner, and the diazo solution is mixed with a solution of 45.0 parts by weight of 1- (2 ', 3'-oxynaphthoylamino) -2 -methoxv-5-bromobenzene in dilute sodium hydroxide solution, which is mixed with a sufficient amount of sodium acetate to bind the excess mineral acid and with Turkish red oil. The precipitated azo dye is filtered off and washed well. Processed in the usual way, advantageously in the form of a paste, with substrates, it provides a red lacquer of high lightfastness. EXAMPLE 8 Pre-bleached pieces of linen are primed like a foulard with a solution containing 20 g of i- (2'-oxycarbazole-3'-carboylamino) -4-chlorobenzene, 20 cc of caustic soda of 341 Be and 30 cc of Turkish red oil (5%) per liter, good squeezed off and dried in between. Then it is developed in a solution on a padder. which contains 3.4 g of i-amino-2,5-dimethoxy-4-cyanobenzene in the form of: the diazonium chloride and aluminum sulfate. After development, it is rinsed, soaped, rinsed again and dried.

Man erhält eine rotstichigbraune Färbung von sehr guter Lichtechtheit.A reddish brown dyeing of very good lightfastness is obtained.
