128,6 Teile der Farbstoffcarbonsäure, die man durch Kuppeln von diazotiertem 1-Amino-2-methoxybenzol-5 carbonsäure-ss-chloräthylester mit 2,3-Hydroxynaphtoesäure erhält, werden in 100 Teilen o-Dichlorbenzol aufgeschlämmt.
Dann werden 12 Teile Thionylchlorid und 0,5 Teile Dimethylformamid zugegeben und das Gemisch 2 Stunden auf 110 "C erhitzt. Die Suspension wird abgekühlt und das ausgefallene reine Säurechlorid abfiltriert, mit Petroläther gewaschen und getrocknet.
89,5 Teile des so hergestellten Azocarbonsäurechlorids und 13,6 Teile 2,5-Dimethyl- 1,4-phenylendiamin werden in 600 Teilen o-Dichlorbenzol eingerührt und auf 140-145 erhitzt.
Bei dieser Temperatur wird die Reaktionsmasse während 16 Stunden gerührt. Dann wird die Suspension heiss abfiltriert und das erhaltene Produkt nacheinander mit warmem o-Dichlorbenzol, Methanol und Wasser gewaschen und getrocknet. Man erhält 89,5 Teile des roten, feinkristallinen Pigmentes der Formel I, das sich gut dispergieren lässt.
Beispiel 2
68 g Polyvinylchlorid-Pulver (Suspensionspolymerisat), 33 g Dioctylphthalat, 2 g Dibutylzinnlaurat, 0,3 g eines Stabilisators auf Phosphatbasis und 0,7 g des nach Beispiel 1 hergestellten Pigmentes werden vermischt und auf dem 1600 heissen Mischwalzwerk während 15 Minuten verarbeitet. Anschliessend wird auf dem Kalander eine Folie von 0,4 mm Dicke hergestellt.
Sie ist in einem reinen carminroten Farbton gefärbt. Die Färbung ist hitzebeständig, licht- und migrationsecht.
Beispiel 3
0,2 g des nach Beispiel 1 hergestellten Pigments, 1 g Titandioxyd (Rutil) und 100 g LD-Polyäthylengranulat werden in einer Trommel gemischt und das Gemisch anschliessend auf dem Mischwalzwerk bei 1300 verarbeitet. Die Masse wird heiss zu Platten verpresst oder in der Strangpresse verformt. Die Platten zeigen einen schönen braunen Farbton von guter Lichtechtheit.
Beispiel 4
0,1 g des nach Beispiel 1 hergestellten Pigmentes, 0,5 g Titandioxyd (Rutil) und 100 g Polypropylengranulat werden in einer Trommel gemischt und das Gemisch anschliessend auf dem Mischwalzwerk bei 1900 verarbeitet, bis eine homogen gefärbte Mischung vorliegt. Die Masse wird heiss zu Platten von 1 mm verpresst. Die Platten zeigen einen reinen carminroten Farbton von guter Lichtechtheit.
Beispiel 5
100 g stabilisiertes Polyvinylchlorid werden mit 1 g eines durch Salzknetung von 0,5 g Pigment mit 0,5 g eines Kopolymerisates aus 85 % Polyvinylchlorid und 15 % Polyvinylacetat erhaltenen Präparates gemischt und 6 Minuten bei 1900 gewalzt.
Das Walzgut wird manuell bewegt, bis eine gute Pigmentverteilung erzielt wird. Die Masse wird nun unter Druck bei 190-200 in der Form wieder abgekühlt. Die auf diese Weise in einem reinen carminroten Farbton eingefärbten Platten zeichnen sich durch eine hohe Wetterechtheit aus.
In der gleichen Weise können aufgehellte wetterechte rote Färbungen von Hart-PVC erzeugt werden, wenn der Ansatz bei gleichem oder reduziertem Buntpigmentanteil zusätzlich Titandioxyd zugefügt wird.
Beispiel 6
10 g Titandioxyd und 2 g des nach Beispiel 1 hergestellten Pigments werden mit 88 g einer Mischung von 26,4 g Kokosal kydharz, 24,0 g Melamin-Formaldehydharz (50% Festkörper gehalt), 8,8 g Äthylenglykolmonomethyläther und 28,8 g Xylol während 48 Stunden in einer Kugelmühle vermahlen.
Wird dieser Lack auf eine Aluminiumfolie gespritzt, 30 Minuten bei Raumtemperatur vorgetrocknet und dann während 30 Minuten bei 120 C eingebrannt, dann erhält man eine Carminlackierung, die sich bei guter Farbstärke durch eine sehr gute tSberlackier-, Licht- und Wetterechtheit auszeichnet.
Beispiel 7
4 Teile des fein verteilten Pigments gemäss Beispiel 1 werden in 20 Teilen Lösungsmittel der folgenden Zusammensetzung eingerührt: 50 Teile Solvesso (Gemisch aromatischer Koh lenstoffe), 15 Teile Butylacetat, 5 Teile Exkin II (Verlaufmittel auf Ketoximbasis), 25 Teile Methyl-Isobutylketon, 5 Teile Sili konöl (1% Solvesso 150).
