Verfahren zum Herstellen von Monoazo- oder Disazo- pigmenten, dadurch gekennzeichnet, dass man a) zu einer Lösung eines Diazonium- und/oder Tetrazoniumsalzes eines aromatischen oder heterocyclischen Amins eine Lösung oder Suspension enthaltend 0,1-50 Gew.% des theoretisch einzusetzenden Gesamtgewichts einer oder mehrerer Kupplungskomponenten zugibt, und b) die Kupplungsreaktion durch Beimischen des gemäss Verfahrensschritt a) erhaltenen teilweise gekuppelten Produkts zu einer Lösung oder Suspension einer oder mehrerer im Verfahrensschritt a) eingesetzten oder davon verschiedenen Kupplungskomponente vervollständigt. Die so hergestellten Pigment zeigen verglichen mit nach herkömmlichen Methoden hergestellten Produkten erhöhte Farbstärke, verbesserte Transparenz, verbesserte Fliesseigenschaften, erhöhte Reinheit und Dispergierbarkeit. |
