Wasserlösliche Mono- oder Polyazoverbindungen, die unter Verwendung von Kupplungskomponenten auf Basis von Resorcinharz aufgebaut sind, besitzen praktisch gleich gutes Aufziehvermögen auf allen Lederarten sowie schön deckende Eigenschaften; deswegen eignen sie sich als Farbstoffe von vorwiegend anionischer Natur sowie aufgrund der damit erzielbaren wertvollen Brauntöne zum Färben insbesondere von kationisch oder anionisch gegerbten bzw. nachgegerbten Lederartikeln, aber auch von Pelzfelllen, entsprechend den üblichen Methoden. Ebenso lassen sich Textilmaterialien aus Cellulose, Seide, Wolle oder synthetischen Polyamidfasern damit färben oder bedrucken. Die Synthese dieser neuen Produkte erfolgt nach herkömmlicher Art durch Diazotieren und Kuppeln. Die Verwendung von Resorcinharz in den erfindungsgemäßen Farbstoffen liefert preisgünstige Ausgangsstoffe und bedeutet einen Beitrag zum Umweltschutz. |
