Der neue Farbstoff wird auf an sich übliche Weise durch Di-.azotieren von 3-Aminodibenzofuran und Kuppeln der Diazoniumverbindung auf 2,6-Dihydroxy-3-oyan-4-methylpyridin hergestellt. Es ist ein brillanter, gelbstichig röter Pigmentfärbst off, der eine sehr gute Lichtechtheit aufweist und überraschend ausgiebige Färbungen ergibt. Beispielsweise ist seine Farbstärke etwa doppelt so hoch wie entsprechende Färbungen, die man unter Verwendung des handelsüblichen, aber schlechter lichtechten Pigmentfarbstoffea· Lake Red 0 (C. I. Pigment Red. 53, Colour Index No/ 15 585) erhält.The new dye is disazotized in a conventional manner of 3-aminodibenzofuran and coupling of the diazonium compound on 2,6-dihydroxy-3-oyan-4-methylpyridine. It is a brilliant, yellowish red pigment color off, which has very good lightfastness and surprisingly extensive coloration. For example, his Color strength about twice as high as corresponding colorations, the one using the commercial, but worse lightfast pigment dyes a Lake Red 0 (C. I. Pigment Red. 53, Color Index No / 15 585).

Aufgrund dieser vorteilhaften Eigenschaften ist der neue rote s| Azofarbstoff insbesondere als Pigmentfarbstoff geeignet.

Beispiel 1 Herstellung:example 1 Manufacturing:

18,3 Teile 3-Aminodibenzofuran werden mit 100 Raumteilen 3-normaler Salzsäure und 200 Teilen Eis in Lösung gebracht. Man tropft 55 Raumteile einer 2-normalen Lösung von Natriumnitrit in Wasser ein und rührt 2 Stunden. Die dabei erhaltene Lösung wird in eine Suspension von 15 Teilen 2,6-Dihydroxy-3-cyan-4-methylpyridin in 300 Raumteilen Wasser eingetropft. Schließlich wird durch Zutropfen einer wässrigen Natriumacetatlösung ein pH-Wert von 5 bis 6 eingestellt und 6 Stunden gerührt. Der Farbstoff wird abgesaugt, mit Wasser gründlich gewaschen und getrocknet. Man erhält 32 Teile eines leuchtend roten Pigmentpulvers.18.3 parts of 3-aminodibenzofuran are brought into solution with 100 parts by volume of 3 normal hydrochloric acid and 200 parts of ice. 55 parts by volume of a 2 normal solution of sodium nitrite in water are added dropwise and the mixture is stirred for 2 hours. The received Solution is in a suspension of 15 parts of 2,6-dihydroxy-3-cyano-4-methylpyridine dripped into 300 parts by volume of water. Finally, an aqueous sodium acetate solution is added dropwise adjusted to a pH of 5 to 6 and stirred for 6 hours. The dye is suctioned off, rinsed with water thoroughly washed and dried. 32 parts of a bright red pigment powder are obtained.

Beispiel 2 Verwendung:Example 2 Use:

a) In Druckfarben: 1 Teil des nach Beispiel 1 hergestellten Pigmentfärbstoffes wird mit 20 Teilen Leinölfirnis auf dem Dreiwalzenstuhl verrieben. Die so hergestellte Druckfarbe gibt bei Verwendung im Buchdruck sehr farbtiefe, brillante gelbstichig-rote Färbungen, die sehr gute Lichtechtheit aufweisen.a) In printing inks: 1 part of the pigment dye prepared according to Example 1 is rubbed with 20 parts of linseed oil varnish on a three-roller mill. When used in letterpress printing, the printing ink produced in this way gives very deep, brilliant yellow-tinged red colorations which have very good lightfastness.

b) Im Lack: 2 Teile des nach Beispiel 1 hergestellten Pigmentes werden mit 98 Teilen Nitrostammlack im Atritor dispergiert. Der Nitrostammlack wurde durch Mischen von 19 Teilen Nitrocellulose butanolfeucht, 4 Teilen eines durch alkalische Kondensation von 85 Teilen Methylcyclohexanon und 15 Teilen Cyclohexanon erhältlichen Harzes, 4,7 Teilen Phthalsäuredibutylester, 4 Teilen Phthalsäurebutylbenzylphthalat, 30 Teilen Butylacetat, 10 Teilen Essigester und 29,3 Teilen Toluol hergestellt. Der gefärbte Nitrolack wird auf Bleche gespritzt und luftgetrocknet. Man erhält eine brillante gelbstichigrote Lackierung von sehr guter Liohtechtheit. b) In the paint: 2 parts of the pigment prepared according to Example 1 are dispersed with 98 parts of nitrous base paint in the atritor. The nitrostammlack was wet by mixing 19 parts of nitrocellulose butanol, 4 parts of a resin obtainable by alkaline condensation of 85 parts of methylcyclohexanone and 15 parts of cyclohexanone, 4.7 parts of dibutyl phthalate, 4 parts of butylbenzyl phthalate, 30 parts of butyl acetate, 10 parts of ethyl acetate and 29.3 parts Toluene produced. The colored nitro lacquer is sprayed onto metal sheets and air-dried. A brilliant yellow-tinged red paintwork of very good lightfastness is obtained.

c) In Kunststoffen: 1 Teil eines nach Beispiel 1 hergestellten Pigmentes wird in 500 Teile Polyvinylchloridpulver und 10 Teilen eines Stabilisators, der aus 7,5 Teilen Dibutylzinnbis-thioglykolsäurehexylester und 2,5 Teilen Dioctylphthalatc) In plastics: 1 part of a pigment prepared according to Example 1 is dissolved in 500 parts of polyvinyl chloride powder and 10 parts of a stabilizer composed of 7.5 parts of dibutyltin bis-thioglycolic acid hexyl ester and 2.5 parts of dioctyl phthalate
