Abstract
Description
Die Erfindung betrifft die Verwendung eines wässrigen Farbstoffkonzentrats als Farbmittel für in automatisch oder mechanisch arbeitenden Vorrichtungen zu benutzende wässrige Aufzeichnungstinte,The invention relates to the use of an aqueous dye concentrate as a colorant for in automatically or Aqueous recording ink to be used with mechanically operating devices,
Aus DE-OS 27 39784 ist es bekannt, aus Konzentraten zweier Direkt-Farbstoffe, zusammen mit Formamid, Diäthanolamin, Zitronensäure, Desinfektionsmittel und Wasser eine derartige wässrige Aufzeichnungstinte für automatisch arbeitende Vorrichtungen - hier Ink-Jet-Systeme u. ä. - herzustellen. Da das hierin zwingend erforderliche Formamid physiologisch nicht unbedenklich ist und außerdem verschiedene Kunststoffe angreift, eignet sich diese Tinte nicht für alle Einsatzgebiete. Zudem entstehen auch bei diesen Tinten relativ schnell feste Farbstoffrückstände bei längerem Maschinenstillstand und Tinte-Verdickungen im Tintenleitsystem.From DE-OS 27 39784 it is known, from concentrates of two direct dyes, together with formamide, diethanolamine, citric acid, Disinfectants and water such an aqueous one Recording ink for automatically operating devices - here ink-jet systems and the like - to be produced. Since the formamide, which is essential here, is not physiologically harmless and also attacks various plastics, this ink is not suitable for all areas of application. In addition, solid inks also develop relatively quickly with these inks Dye residues after long machine downtimes and Ink thickening in the ink feed system.
Aufgabe der Erfindung ist es daher, eine Aufzeichnungstinte für derartige Ausgabevorrichtungen zu schaffen, die gesundheitlich unbedenklich ist, gute allgemeine Materialverträglichkeit aufweist und die längere Stillstandszeiten ohne Eintrocknungsoder Verdickungserscheinungen ermöglicht. The object of the invention is therefore to provide a recording ink for to create such dispensing devices, which is harmless to health, has good general material compatibility and which enables longer downtimes without drying out or thickening.
Diese Aufgabe wird mit den im Hauptanspruch umfaßten Merkmalen auf überraschend einfache Weise gelöst.This object is achieved in a surprisingly simple manner with the features encompassed in the main claim.
