Description

Die Erfindung betrifft einen polyolefinbeschichteten Schichtträger für thermische Farbstoffübertragungsverfahren sowie ein Verfahren zu dessen Herstellung.The invention relates to a polyolefin-coated substrate for thermal dye transfer processes and a process for its production.

Das System der thermischen Farbstoffübertragung (Dye Diffusion Thermal Transfer "D2T2") ermöglicht die Wiedergabe eines elektronisch erzeugten Bildes in Form einer "Hard Copy". Das Prinzip der thermischen Farbstoffübertragung besteht darin, daß das digitale Bild hinsichtlich der Grundfarben Cyan, Magenta, Gelb und Schwarz aufbereitet und in entsprechende elektrische Signale umgewandelt wird. Diese Signale werden zu einem Thermodrucker weitergeleitet und in Wärme umgesetzt.The system of thermal dye transfer (Dye Diffusion Thermal Transfer "D2T2") enables the reproduction of an electronically generated image in the form of a "hard copy". The principle of thermal dye transfer is that the digital image is processed with regard to the primary colors cyan, magenta, yellow and black and converted into corresponding electrical signals. These signals are forwarded to a thermal printer and converted into heat.

Durch die Wärmeeinwirkung sublimiert der Farbstoff aus der Donorschicht eines im Kontakt mit dem Empfangsmaterial stehenden Farbbandes (Farbblattes) und diffundiert in die Empfangsschicht hinein.Due to the action of heat, the dye sublimes from the donor layer of an ink ribbon (ink sheet) in contact with the receiving material and diffuses into the receiving layer.

Ein Empfangsmaterial für thermische Farbstoffübertragung besteht in der Regel aus einem Träger mit auf dessen Vorderseite aufgebrachter Empfangsschicht.A receiving material for thermal dye transfer generally consists of a support with a receiving layer applied to its front.

Als Träger kann eine Kunststoffolie, z. B. Polyesterfilm, ein synthetisches oder ein harzbeschichtetes Papier dienen.A plastic film, e.g. B. polyester film, a synthetic or a resin-coated paper.

Die Hauptkomponente der Empfangsschicht ist in der Regel ein thermoplastisches Harz, das eine Affinität zum Farbstoff aus dem Farbband aufweist, wie z. B. Polyester oder Acrylharze.The main component of the receiving layer is usually a thermoplastic resin that has an affinity for the dye from the ribbon, such as. B. polyester or acrylic resins.

Außer einer Empfangsschicht werden oft noch andere Schichten auf die Vorderseite des Trägers aufgebracht, wie z. B. Sperr, Trenn-, Haft- und Schutzschichten.In addition to a receiving layer, other layers are often applied to the front of the carrier, such as e.g. B. barrier, separating, adhesive and protective layers.

An ein Farbstoffempfangsmaterial werden hohe Anforderungen gestellt, deren Erfüllung bei dem übertragenen Bild eine hohe Farbdensität und Bildschärfe (Strichschärfe) sichern soll.High demands are placed on a dye-receiving material, the fulfillment of which is intended to ensure high color density and image sharpness (line sharpness) in the transferred image.

Aus dem Stand der Technik sind verschiedene Wege zur Optimierung eines Farbstoffempfangsmaterials bekannt, z. B. über den Träger, oder durch das Aufbringen verschiedener Funktionsschichten und/oder durch eine spezifische Auswahl und Zusammensetzung der Empfangsschicht.Various ways of optimizing a dye-receiving material are known from the prior art, e.g. B. on the carrier, or by applying different functional layers and / or by a specific selection and composition of the receiving layer.

In der Patentschrift US 4,774,224 wird ein Empfangsmaterial beansprucht, dessen polyethylenbeschichtete Papierunterlage eine Oberflächenrauhigkeit (Ra) höchstens 7,5 µinch aufweisen muß.US Pat. No. 4,774,224 claims a receiving material whose polyethylene-coated paper base must have a surface roughness (Ra) of at most 7.5 μinch.

In einer anderen Patentanmeldung Nr. J 02229 082 wird ein Empfangsmaterial beschrieben, bei dem der polyethylenbeschichtete Papierträger Rauhigkeitswerte in Höhe von 8 bis 160 µinch aufweist.Another patent application No. J 02229 082 describes a receiving material in which the polyethylene-coated paper support has roughness values of 8 to 160 μinch.

Nachteilig an beiden Empfangsmterialien ist, daß nicht jede polyethylenbeschichtete Papierunterlage mit den beanspruchten Rauhigkeitswerten der PE-Oberfläche sowohl unterhalb als auch oberhalb von 7,5 µinch gute Ergebnisse hinsichtlich der Farbdensität und Bildschärfe des übertragenen Bildes garantiert.A disadvantage of both receiving materials is that not every polyethylene-coated paper base with the claimed roughness values of the PE surface guarantees good results with regard to the color density and image sharpness of the transmitted image both below and above 7.5 µinch.

Der vorliegenden Erfindung liegt nun die Aufgabe zugrunde, einen Schichtträger für thermische Farbstoffübertragungs-verfahren zu entwickeln, welcher nach dem Auftragen einer Empfangsschicht ein Empfangsmaterial sicherstellen soll, welches die Erzeugung von Bildern hoher Auflösung (Strichschärfe) und Farbdichte ermöglicht.The present invention is based on the object of developing a substrate for thermal dye transfer processes which, after the application of a receiving layer, is intended to ensure a receiving material which enables the generation of images of high resolution (line sharpness) and color density.

Diese Aufgabe wird dadurch gelöst, daß als Schichtträger für ein Empfangsmaterial für thermische Farbstoffübertragung ein Basispapier mit einer Oberflächenrauhigkeit (Ra)von 4 µm oder weniger und mit einer darauf angeordneten Polyethylen-beschichtung in einer Auftragsmenge von höchstens 30 g/m² verwendet wird.This object is achieved in that a base paper with a surface roughness (Ra) of 4 μm or less and with a polyethylene coating arranged thereon is used as a layer support for a receiving material for thermal dye transfer in an application amount of at most 30 g / m².

Überraschenderweise hat sich herausgestellt, daß entgegen den im Stand der Technik gemachten Behauptungen die Rauhigkeit des Basispapiers eines Schichtträgers für thermische Farbstoffübertragungsverfahren bei der Qualität des später übertragenen Bildes eine Rolle spielt.Surprisingly, it has been found that, contrary to the claims made in the prior art, the roughness of the base paper of a substrate for thermal dye transfer processes plays a role in the quality of the image subsequently transferred.

Es hat sich herausgestellt, daß die Einhaltung des Rauhigkeitswertes des Basispapiers von <4 µm und einer Auftragsmenge der Polyolefinbeschichtung von <30 g/m² eine hohe Farbdensität und Auflösung (Strichschärfe) des übertragenen Bildes ermöglicht.It has been found that compliance with the roughness value of the base paper of <4 µm and an application amount of the polyolefin coating of <30 g / m² enables a high color density and resolution (line sharpness) of the transferred image.

Dies gilt nicht nur für glänzende Oberflächen des polyolefinbeschichteten Schichtträgers (Ra <0,2 µm), sondern auch für PE-Oberflächen mit größerer Rauhtiefe (> 0,2 µm).This applies not only to glossy surfaces of the polyolefin-coated substrate (Ra <0.2 µm), but also to PE surfaces with a greater surface roughness (> 0.2 µm).

In einer bevorzugten Ausführung der Erfindung beträgt die Rauhigkeit des Basispapiers 2,5 µm oder weniger.In a preferred embodiment of the invention, the roughness of the base paper is 2.5 μm or less.

In einer anderen bevorzugten Ausführung ist die Auftragsmenge der Polyolefinbeschichtung kleiner als 15 g/m².In another preferred embodiment, the application amount of the polyolefin coating is less than 15 g / m².

Die Polyolefinbeschichtung kann aus Polyethylen hoher (HDPE) und/oder niedriger Dichte (LDPE) oder aus Polypropylen bestehen. Zusätzlich kann die Polyolefinbeschichtung Pigmente, wie z.B. TiO₂ und andere Zusatzstoffe enthalten.The polyolefin coating can consist of high (HDPE) and / or low density polyethylene (LDPE) or of polypropylene. In addition, the polyolefin coating can contain pigments such as e.g. Contain TiO₂ and other additives.

Erfindungsgemäß enthält die Polyolefinbeschichtung wenigstens 30 % HDPE, bevorzugt 40 - 80 % HDPE.According to the invention, the polyolefin coating contains at least 30% HDPE, preferably 40-80% HDPE.

Die Erfindung wird mit Hilfe der nachfolgenden Beispiele näher erläutert.The invention is explained in more detail with the aid of the following examples.

Prüfung des gemäß Beispiel 1 und 2 hergestellten SchichtträgersTesting of the layer support produced according to Examples 1 and 2

Die mit einer Bildempfangsschicht versehenen erfindungsgemäßen Schichtträger wurden einem thermischen Bildübertragungs-verfahren unterzogen. Hierzu wurde ein Colour Video Printer VY - 25E der Fa. Hitachi eingesetzt unter Anwendung eines Hitachi-Farbbandes. Der Video-Printer hat folgende technische Daten: Bildspeicher: PAL 1-Vollbild-Speicher Druckbild: 64 Farbton-Bild Bildelemente: 540:620 Punkte Druckzeit: 2 Minuten/Bild The layer supports according to the invention provided with an image receiving layer were subjected to a thermal image transfer process. For this purpose, a color video printer VY - 25E from Hitachi was used using a Hitachi ink ribbon. The video printer has the following technical data: Image storage: PAL 1 full screen memory Print image: 64 color image elements: 540: 620 points Printing time: 2 minutes / picture

Bei den erhaltenen Druckbildern (Hardcopy) wurden die Farbdensität und die Stichschärfe untersucht.The color density and the sharpness of the stitch were examined in the print images obtained (hard copy).

Die Densitätsmessungen wurden mit Hilfe eines Densitometers (Original Reflection Densitometer SOS-45) durchgeführt. Die Messungen erfolgten für die Grundfarben Cyan, Magenta, Gelb und Schwarz.The density measurements were carried out using a densitometer (Original Reflection Densitometer SOS-45). The measurements were carried out for the basic colors cyan, magenta, yellow and black.

Die Strichschärfe wurde an Hand von in den Grundfarben geprinteten Testbildern ermittelt. Das Testbild zeigt gerade Linien, die wowohl horizontal als auch vertikal geprintet sind. Die Messung erfolgt mit einem Fadenzähler an drei Meßstellen. Daraus wird das arithmetische Mittel berechnet. Je kleiner der gemessene Wert der Strichbreite ist, desto höher ist die Schärfe des Bildes.The line sharpness was determined on the basis of test images printed in the basic colors. The test image shows straight lines that are printed both horizontally and vertically. The measurement is carried out with a thread counter at three measuring points. The arithmetic mean is calculated from this. The smaller the measured value of the stroke width, the higher the sharpness of the picture.

Außer den o.g. Messungen wurden die Druckbilder visuell begutachtet und das Auftreten von Ungleichmäßigkeiten auf der Bildoberfläche, wie z.B. das Auftreten weißer Punkte sog. "Missing dots" (keine Farbstoffaufnahme) zur Beurteilung der Bildqualität herangezogen.In addition to the above Measurements were visually inspected the printed images and the appearance of irregularities on the image surface, such as the occurrence of white dots, so-called "missing dots" (no dye absorption), is used to assess the image quality.

Die in den Tabellen 1 und 2 aufgeführten Ergebnisse zeigen, daß mit dem erfindungsgemäß hergestellten Schichtträger ein Bildempfangsmaterial erzeugt werden kann, welches eine höhere Farbdensität und Bildschärfe der gedruckten Bilder im Vergleich zum herkömmlichen Empfangsmaterial aufweist.
