Description

Verfahren zur Herstellung von wasserunlöslichen Monoazofarbstoffen Es wurde gefunden, daß man wertvolle wasserunlösliche Monoazofarbstoffe erhält, wenn man eine Aminoverbindung der allgemeinen Formel worin X Wasserstoff, Halogen, eine Alkyl- oder Alkoxygruppe, R, Wasserstoff oder eine Alkylgruppe und R2 einen niedrigmolekularen aliphatischen Säurerest, vorzugsweise einen Acetylrest bedeutet, dianotiert und mit von wasserlöslichmachenden Gruppen freien Azokomponenten der 2,3-Oxynaphthoesäurearylamid- oder Acylessigsäurearylamidreihe umsetzt.Process for the preparation of water-insoluble monoazo dyes It has been found that valuable water-insoluble monoazo dyes are obtained if an amino compound of the general formula is used where X is hydrogen, halogen, an alkyl or alkoxy group, R, hydrogen or an alkyl group and R2 is a low molecular weight aliphatic acid radical, preferably an acetyl radical, dianotized and reacted with azo components of the 2,3-oxynaphthoic arylamide or acylacetic arylamide series which are free from water-solubilizing groups.

Verfahrensgemäß zu verwendende Diazokomponenten sind beispielsweise 1-Aminobenzol-3-sulfonsäureacetylamid, 1-Aminobenzol-2-chlor-5-sulfonsäure-N-methyl-N-acetylamid, 1-Aminobenzol-2-methyl-5-sulfonsäureacetylamid, 1-Aminobenzol-2-methoxy-5-sulfonsäureacetylamid.Diazo components to be used according to the method are, for example 1-aminobenzene-3-sulfonic acid acetylamide, 1-aminobenzene-2-chloro-5-sulfonic acid-N-methyl-N-acetylamide, 1-aminobenzene-2-methyl-5-sulfonic acid acetylamide, 1-aminobenzene-2-methoxy-5-sulfonic acid acetylamide.

Als Azokomponenten werden die für die Herstellung von Azopigmentfarbstoffen gebräuchlichen Arylamide der 2-Oxynaphthalin-3-carbonsäure und der Acetessigsäure verwendet.The azo components are used for the production of azo pigment dyes common arylamides of 2-oxynaphthalene-3-carboxylic acid and acetoacetic acid used.

Die Kupplung der Ausgangskomponenten erfolgt nach üblichen Verfahren in vorzugsweise saurem wäßrigem Medium.The starting components are coupled using customary methods in preferably acidic aqueous medium.

Die so erhältlichen Pigmentfarbstoffe eignen sich besonders zum Färben von Lacken und Kunststoffen, zum Bedrucken und Färben von Textilien und Papier nach den üblichen Pigmentdruck- und Färbeverfahren und zur Faserspinnfärbung. Sie zeichnen sich durch sehr gute Lichtechtheit aus und sind gut lösungsmittel-und überspritzecht.The pigment dyes obtainable in this way are particularly suitable for dyeing of paints and plastics, for printing and dyeing textiles and paper the usual pigment printing and dyeing processes and for fiber spin dyeing. they draw are characterized by very good lightfastness and are well solvent-sprayed and sprayed over.

Gegenüber dem aus der deutschen Patentschrift 821977, Beispiel 4, bekannten wasserunlöslichen Monoazofarbstoff zeichnet sich der erfindungsgemäß aus dianotiertem 1-Aminobenzol-3-sulfonsäureacetylamid und Acetoacetylaminobenzol erhältliche Farbstoff durch wesentlich verbesserte Lösungsmittelechtheit aus.Compared to that from the German patent specification 821977, Example 4, known water-insoluble monoazo dye is distinguished according to the invention dianotated 1-aminobenzene-3-sulfonic acid acetylamide and acetoacetylaminobenzene are available Dye is characterized by significantly improved solvent fastness.

In den folgenden Beispielen stehen Volumteile zu Gewichtsteilen im Verhältnis von Millilitern zu Gramm.In the following examples, parts by volume are related to parts by weight Ratio of milliliters to grams.

Beispiel 1 24,4 Gewichtsteile 1-Amino-2-methoxybenzol-5-sulfonsäureacetylamid werden in üblicher Weise dianotiert. Zu der geklärten Diazotierungslösung werden 25 Volumteile Eisessig und anschließend die wäßrige Lösüng des Natriumsalzes von 36 Gewichtsteilen 1-(2',3' - Hydroxynaphthoylamino) -5-chlor-2,4-dimethoxybenzol gegeben. Nach Beendigung der Kupplung wird der entstandene Farbstoff abgesaugt, gewaschen und getrocknet.Example 1 24.4 parts by weight of 1-amino-2-methoxybenzene-5-sulfonic acid acetylamide are dianotated in the usual way. Become the clarified diazotization solution 25 parts by volume of glacial acetic acid and then the aqueous solution of the sodium salt of 36 parts by weight of 1- (2 ', 3' -hydroxynaphthoylamino) -5-chloro-2,4-dimethoxybenzene given. After the coupling has ended, the resulting dye is suctioned off, washed and dried.

3 Gewichtsteile des so erhaltenen Pigmentfarbstoffes werden in 100 Gewichtsteilen eines Nitroalkyd-Harzlackes (mit einem Festkörpergehalt von etwa 22%) in einer Trichtermühle angerieben. Mit dem auf Spritzviskosität eingestellten Lack lassen sich bordofarbene Lackierungen mit sehr guter Überspritzechtheit und hoher Lichtechtheit erzielen.3 parts by weight of the pigment dye thus obtained are in 100 Parts by weight of a nitroalkyd resin varnish (with a solids content of approx 22%) ground in a funnel mill. With the set to spray viscosity Lacquer can be bordo-colored lacquers with very good overspray fastness and achieve high lightfastness.

Beispiel 2 24,8 Gewichtsteile 1-Amino-2-chlorbenzol-5-sulfonsäureacetylamid werden wie üblich dianotiert und, ähnlich wie im Beispiel 1, mit 27 Gewichtsteilen 1-(2',3'-Hydroxynaphthoylamino)-benzol gekuppelt.Example 2 24.8 parts by weight of 1-amino-2-chlorobenzene-5-sulfonic acid acetylamide are dianotized as usual and, similar to Example 1, with 27 parts by weight 1- (2 ', 3'-hydroxynaphthoylamino) benzene coupled.

Dispergiert man 20 Gewichtsteile des isolierten Farbstoffes mit 75 Volumteilen Wasser und 5 Gewichtsteilen eines Dispergiermittels, so lassen sich mit dieser Dispersion nach Einarbeiten in übliche Druckpasten orangefarbene Textildrucke von sehr guten Naß- und Lichtechtheiten erzielen.20 parts by weight of the isolated dye are dispersed with 75 Parts by volume of water and 5 parts by weight of a dispersant can be with this dispersion, after incorporation into customary printing pastes, orange-colored textile prints achieve very good wet and light fastness properties.
