Abstract

Water-insol. disazo dye has the formula (I). Dye (I) is prepd. by coupling tetrazotised 3,3'-dichloro-4,4' diaminodiphenyl with 1-acetoacetylamino-2-methoxy-4-methylbenzene. (I) is a water-insoluble pigment with a clear yellow colour. (I) is suitable for use with vinyl polymers super polyamides, polyurethanes, or polyesters, and for use in paints and printing inks.

Description

  

  
 



  Verfahren zur Herstellung eines wasserunlöslichen Disazofarbstoffs
Es wurde gefunden, dass man einen wertvollen wasserunlöslichen Disazopigmentfarbstoff erhält, wenn man   tetazodertes    3,3'-Dichlor-4,4'-diaminodiphenyl mit 1-Acetoacetylamino-2-methoxy-4-methyl-benzol kuppelt.



  Die Umsetzung der Ausgangskomponenten erfolgt bevorzugt in saurer wässriger Lösung oder Suspension bei Temperaturen von -5 bis 200 C.



   Der neue Farbstoff entspricht der Formel:
EMI1.1     
 und stellt ein wasserunlösliches Pigment von klarer gelber Farbe dar. Er eignet sich infolge seiner hohen Farbkraft, seiner ausgezeichneten Lösungsmittelbeständigkeit, seiner hohen   Lichtechtheit    und seiner hohen Transparenz insbesondere zum Färben von Kunststoffen wie Vinylpolymerisaten, Superpolyamiden, Superpolyurethanen oder Polyestern und für den graphischen Druck sowie für spezielle Gebiete der Lack-, Tapeten- und Papierindustrie.



   Beispiel
25,3 g   3,3'-Dichlor < 4,4'aminodliphenyl    werden in 1000 g Wasser und 85   ml    Salzsäure   (20       Bé   heiss   ge;    löst, filtriert und mit Eis auf ca.   0     C   abgekiihlt.    Dann wirdi mit einer konzentrierten wässrigen Lösung von 14 g Natriumnitrit tetrazotiert.



   41 g 1-Acetoacetylamino-2-methoxy-4-methyl-benzol werden in 1000 g Wasser und 25 ml Natronlauge   (25     Be) klar gelöst, auf   5-100    C abgekühlt und durch rasches Zugeben von 9   ml    Eisessig in feiner   Suspen    sion ausgefällt. Zu dieser Suspension lässt man die farblose Tetrazotierungslösung in dem Masse zulaufen, wie die Kupplungsreaktion fortschreitet. Der pH-Wert kann dabei durch Zugabe von Natriumacetat vorteilhaft auf 3-7 gehalten werden. Wenn die Realtion   be;    endet ist, wird auf   40-100     C erhitzt, der so erhaltene gelbe Pigmentfarbstoff abgesaugt und bei   50-60     C getrocknet.

  Process for the preparation of a water-insoluble disazo dye
It has been found that a valuable water-insoluble disazo pigment dye is obtained when tetazoderted 3,3'-dichloro-4,4'-diaminodiphenyl is coupled with 1-acetoacetylamino-2-methoxy-4-methylbenzene.



  The starting components are preferably reacted in an acidic aqueous solution or suspension at temperatures from -5 to 200 C.



   The new dye corresponds to the formula:
EMI1.1
 and is a water-insoluble pigment of clear yellow color. Due to its high color strength, its excellent solvent resistance, its high lightfastness and its high transparency, it is particularly suitable for coloring plastics such as vinyl polymers, super polyamides, super polyurethanes or polyesters and for graphic printing and for special areas of the paint, wallpaper and paper industry.



   example
25.3 g of 3,3'-dichloro <4,4'aminodliphenyl are dissolved in 1000 g of water and 85 ml of hydrochloric acid (20 Bé hot;), filtered and cooled to about 0 ° C. with ice. Then, a concentrated aqueous solution is used Solution of 14 g of sodium nitrite tetrazotized.



   41 g of 1-acetoacetylamino-2-methoxy-4-methyl-benzene are dissolved in 1000 g of water and 25 ml of sodium hydroxide solution (25 Be), cooled to 5-100 ° C. and precipitated in a fine suspension by quickly adding 9 ml of glacial acetic acid . The colorless tetrazotization solution is allowed to run into this suspension as the coupling reaction progresses. The pH can advantageously be kept at 3-7 by adding sodium acetate. If the Realtion be; ends, the mixture is heated to 40-100 ° C., the yellow pigment dye thus obtained is filtered off with suction and dried at 50-60 ° C.
