Claims (4)
1. Wärmeempfindliches eingefärbtes Element mit einem Kunststoffträger, der auf der einen Seite mit einer getrockneten klebenden Überzugsschicht aus einem Gemisch überzogen ist, das auf das zu bedruckende Substrat übertragbar ist, wenn es Wärme und Druck ausgesetzt wird, und einen Farbstoff sowie ein Bindemittel aufweist, das aus einer Mischung aus wenigstens einem thermoplastischen Harz und wenigstens einem Wachs besteht, dadurch gekennzeichnet, daß für anschlaglose thermische Punktdrucker der Träger eine Dicke von 5 bis 15 um aufweist und daß die Überzugsschicht eine Dicke von 2 bis 6 um aufweist und aus einem Bindemittel besteht, das aus einem thermoklebfähigen polymeren Harz und einem heißschmelzenden Klebstoff in einem Gewichtsverhältnis von etwa 3 zu 1 besteht, wobei das polymere Harz aus einem Polystyrol mit einem Erweichungspunkt von etwa 100°C oder einem veresterten Kolophonium oder Harz besteht, der heißschmelzende Klebstoff aus einem Gemisch aus thermoplastischem Harz und einem Kohlenwasserstoff oder Paraffinwachs besteht und einen Erweichungspunkt zwischen 70° und 80°C aufweist, zusammen mit dem Farbstoff, der in einer Menge vorhanden ist, die im wesentlichen gleich dem Gewicht des heißschmelzenden Klebstoffs ist.
2. Element nach Anspruch 1, dadurch gekennzeichnet, daß der Farbstoff schwarz ist und daß das Gemisch zusätzlich komplementäre Farben von insgesamt 56 Gewichtsprozent des Farbstoffs aufweist, um der Schwärze einen intensiveren Farbton zu geben.
3. Element nach Anspruch 2, dadurch gekennzeichnet, daß der Farbstoff aus Solventschwarz 3 (C.I. 26150) gebildet ist und das Gemisch zusätzlich Zyan, Magenta und gelbe Farben enthält.
4. Element nach Anspruch 3, dadurch gekennzeichnet, daß die komplementären Farben in Gewichtsprozent des Farbstoffs aufweisen: 12% Pigmentblau 15 (C.I. 74160), 32% Pigmentrot 57 (C.I. 15850:1) und 12% Pigmentgelb (C.I. 21095).
