Description
Die Erfindung betrifft ein mit einer Farbbandfarbe ge tränktes Gewebe-Farbband.The invention relates to a ge with a ribbon color soaked fabric ribbon.
Bekannte Farbbänder dieser Art enthalten neben flüssi gen Farbstoffen, Farbbasen, Ölen und Additiven zur Ver besserung des Fließverhaltens vornehmlich aus Ruß be stehende Farbpigmente. Die Partikelgröße der Farbpig mente liegt dabei in der Größenordnung von 0,003 bis 0,012 mm.Known ribbons of this type contain liquid dyes, color bases, oils and additives for ver improvement of the flow behavior mainly from soot standing color pigments. The particle size of the color pig mente is in the order of 0.003 to 0.012 mm.
Der Erfindung liegt die Aufgabe zugrunde, ein Farbband der in Betracht gezogenen Art zu schaffen, das einer seits eine gegenüber bekannten Farbbändern erhöhte Stand zeit aufweist und das andererseits ein verbessertes Schriftbild liefert. Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Partikelgröße der Farbpigmente maximal 0,0025 mm beträgt.The invention has for its object a ribbon of the kind contemplated to create that one on the one hand a higher level than known ribbons has time and on the other hand an improved Typeface supplies. This object is achieved according to the invention solved in that the particle size of the color pigments is a maximum of 0.0025 mm.
Untersuchungen haben gezeigt, daß durch die Verminderung der Partikelgröße der Farbpigmente Vorteile erzielt wer den, deren Ausmaß überraschend ist. So ist u. a. die Farbabgabe pro Anschlag auf das Papier geringer, und trotz der dünneren Farbschicht auf dem Papier wird eine bessere Farbabdeckung durch eine gleichmäßigere Ver teilung der Farbpigmente erreicht. Die Farbintensität des Schriftbildes nimmt bei gleichzeitiger Erhöhung der Standzeit des Farbbandes zu. Als vorteilhaft erweist sich zudem, daß die Verschmutzung von Typen, Nadeln und Nadelkanälen abnimmt und daß beispielsweise bei hochwer tigen Nadeldruckern mit nur 0,2 mm dicken Nadeln in ebenso engen Nadelkanälen der Verschleiß von Nadeln und Nadelkanälen deutlich zurückgeht. Schließlich erhöht die kleinere Partikelgröße auch das Fließverhalten der Farbe im Farbband.Research has shown that through the reduction The particle size of the color pigments achieves advantages the one whose size is surprising. So u. a. the Color delivery per stroke on the paper less, and despite the thinner layer of color on the paper, better color coverage due to a more uniform ver division of the color pigments achieved. The color intensity of the typeface increases while increasing the Ribbon life too. Proves to be advantageous also that the pollution of types, needles and Needle channels decreases and that, for example, at high dot matrix printers with needles only 0.2 mm thick just as narrow needle channels the wear of needles and Needle channels decrease significantly. Finally increased the smaller particle size also the flow behavior of the Color in the ribbon.
In der Praxis sollte die Partikelgröße mindestens 0,0005 mm betragen. Gute Ergebnisse wurden mit Farbpig menten aus Ruß erreicht.In practice, the particle size should be at least 0.0005 mm. Good results were achieved with color pig reached from soot.
Neben Farbpigmenten kann die Farbbandfarbe, wie an sich bekannt, flüssige Farbstoffe, z. B. Oleat violett oder Oleat blau, eine Farbbase, insbesondere eine Orange base, Öle als Binde- und Auflösungsmittel und Additive zur Verbesserung des Fließverhaltens aufweisen.In addition to color pigments, the ribbon color, as such known liquid dyes, e.g. B. violet or oleate Oleat blue, a color base, especially an orange base, oils as binding and dissolving agents and additives to improve the flow behavior.
