Chinazolon-AzopigmenteQuinazolone azo pigments
Zusatz zum Patent 2 219 169 und Zusatz zum Zusatzpatent (Patentanmeldung 26 55 522.6) Das Hauptpatent betrifft Farbstoffe der Formel I in der R1 Wasserstoff, Chlor, Brom oder Nitro, R2 und R3 Wasserstoff oder Chlor R4 Wasserstoff, Chlor oder Methyl und X Cyan oder Carbamoyl bedeuten.Addendum to patent 2,219,169 and addendum to additional patent (patent application 26 55 522.6) The main patent relates to dyes of the formula I in which R1 is hydrogen, chlorine, bromine or nitro, R2 and R3 are hydrogen or chlorine, R4 is hydrogen, chlorine or methyl and X is cyano or carbamoyl.
Das Zusatzpatent betrifft Farbstoffe der Formel 1> I, beidenen die Methylgruppe des Pyridinringes durch Wasserstoff ersetzt ist.The additional patent relates to dyes of the formula 1> I, both the methyl group of the pyridine ring is replaced by hydrogen.
Es wurde nun gefunden, daß Verbindungen der Formel II der B Wasserstoff oder Methyl, Y Chlor oder Brom und Z Wasserstoff, Chlor oder Brom bedeuten und Rl, R2, R3 und X die angegebenen Bedeutungen haben, ebenfalls vorziigliche Eigenschaften aufweisen.It has now been found that compounds of the formula II where B is hydrogen or methyl, Y is chlorine or bromine and Z is hydrogen, chlorine or bromine and Rl, R2, R3 and X have the meanings given, also have excellent properties.
Die neuen Farbstoffe haben Pigmentcharakter und zeichnen sich in ihren Anwendungen durch sehr gute Lösungsmittelechtheiten in allen Lösungsmitteln, Migrationsechtheit, Uberlackier- und Uberspritzechtheit und gute Lichtechtheit aus. Man erhält damit sehr brillante gelbe bis orangefarbene Färbungen.The new dyes are pigmentary and stand out in their Applications due to very good solvent fastness in all solvents, migration fastness, Fastness to overcoat and overmold and good fastness to light. One obtains with it very brilliant yellow to orange colors.
Einzelne Pigmente der Formel II sind durch außerordentlich hohe Ausgiebigkeit und Farbstärke gekennzeichnet oder sie zeigen in geeigneter physikalischer Form ein ungewöhnlich hohes Deckvermögen.Individual pigments of the formula II are extremely voluminous and color strength or they show in a suitable physical form an unusually high hiding power.
Gegenüber den Verbindungen des Hauptpatentes zeichnen sich die neuen Verbindungen durch weiter gesteigerte Unlöslichkeit und Farbstärke aus.Compared to the connections of the main patent, the new ones stand out Compounds by further increased insolubility and color strength.
Zur Herstellung der Verbindungen der Formel II kann man ein Diazoniumsalz von.Aminen der Formel III mit einer Kupplungskomponente der Formel 'umsetzen. Hinsichtlich der Verxsendung und weiterer Einzelheiten gelten die Angaben des Haupt- und Zusatzpatentes.To prepare the compounds of the formula II, a diazonium salt of amines of the formula III with a coupling component of the formula 'realize. With regard to the shipment and further details, the details of the main and additional patent apply.
In den nachfolgenden Beispielen beziehen sich Teile und Prozente auf das Gewicht. Temperaturen sind in Celsiusgraden angegeben.In the following examples, parts and percentages relate to the weight. Temperatures are given in degrees Celsius.
Beispiel 1 15>3 Teile 2-(3',5'-Dichlor-4'-aminophenyl)-chinazolon-4
werden in einer Mischung aus 250 Teilen Eisessig, 50 Teilen Propionsäure und 30
Teilen konzentrierter Salzsäure bei 500 gelöst, auf Oo gekühlt und durch Zugabe
von 3,5 Teilen Natriumnitrit diazotiert. Nach einer Stunde wird überschüssiges Nitrit
mit Amidosulfonsäure zerstört. Dann läßt 0 man bei 5 eine Lösung von 7,5 Teilen
2,6-Dihydroxy-3-cyan-4-methyl-pyridin in 100 Teilen Äthanol und 3 Teilen Natriumhydroxid
zulaufen, rührt 2 Stunden bei Raumtemperatur, filtriert und wäscht mit Wasser. Das
wasserfeuchte Rohpigment wird in 200 Teilen N-Methylpyrrolidon langsam auf 1300
erhitzt, wobei Wasser abdestilliert, 2 Stunden gerührt, heiß filtriert, mit Methanol
gewaschen und getrocknet. Man erhält 21 Teile eines orangefarbenen Pulvers der Formel
Auf analoge Weise erhält man die durch Angabe der Diazo- und Kupplungskomponente
gekennzeichneten Pigmente:
Beispiel Teile Amin Teile Teile Farbton'
