Abstract
Description
Die Erfindung betrifft ein Bildempfangsmaterial für thermische Farbstoffübertragung sowie ein Verfahren zu dessen Herstellung.The invention relates to an image-receiving material for thermal dye transfer and a method for its production.
In den letzten Jahren wurde ein System der thermischen Farbstoffübertragung (Dye Diffusion Thermal Transfer - "D2T2") entwickelt, welches die Wiedergabe eines elektronisch erzeugten Bildes in Form einer "Hardcopy" ermöglicht.A dye diffusion thermal transfer ("D2T2") system has been developed in recent years, which enables the reproduction of an electronically generated image in the form of a "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.
Durch die Wärmeeinwirkung sublimiert der Farbstoff aus der Donorschicht eines im Kontakt mit dem Empfangsmaterial stehenden Farbbandes (Farbblattes) und diffundiert in die Empfangsschicht hinein.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.
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. Außer der Empfangsschicht werden oft noch andere Schichten auf die Vorderseite des Trägers aufgebracht. Dazu gehören u. a. Sperr-, Trenn-, Haft-, und Schutzschichten.A receiving material for thermal dye transfer generally consists of a carrier with a receiving layer applied to its front. In addition to the receiving layer, other layers are often applied to the front of the carrier. These include a. Barrier, separating, adhesive and protective layers.
Die Notwendigkeit der zusätzlichen Schichten ist durch die an das Empfangsmaterial gestellten Anforderungen begründet, wie:
- glatte Oberfläche
- Hitze- und Druckstabilität
- Lichtstabilität, kein Vergilben
- gute Farbstofflöslichkeit
- gute Kratz- und Abriebfestigkeit
- "anti-blocking"-Eigenschaften (kein Kleben)
- smooth surface
- Heat and pressure stability
- Light stability, no yellowing
- good dye solubility
- good scratch and abrasion resistance
- "anti-blocking" properties (no sticking)
Die Hauptkomponente der Empfangsschicht ist in der Regel ein thermoplastisches Harz, das eine Affinität zum Farbstoff aus dem Farbband aufweist. Dazu gehören lineare Polyester, z. B. Polyethylenterephthalat, Polybutylenterephthalat oder Acrylharze, z. B. Polymethylmethacrylat, Polybutylmethacrylat, Polymethylacrylat usw.. Weiterhin können Polystyrol, Polycarbonat, Polyvinylpyrrolidon, Ethylcellulose, Polysulfon und andere Kunststoffe als farbstoffaufnehmendes Harz verwendet werden.The main component of the receiving layer is usually a thermoplastic resin that has an affinity for the dye from the ribbon. These include linear polyesters, e.g. B. polyethylene terephthalate, polybutylene terephthalate or acrylic resins, e.g. B. polymethyl methacrylate, polybutyl methacrylate, polymethylacrylate, etc. Furthermore, polystyrene, polycarbonate, polyvinylpyrrolidone, ethyl cellulose, polysulfone and other plastics can be used as the dye-absorbing resin.
Aus den Patentschriften US 4 748 150 und US 4 774 224 ist bekannt, daß auf ein polyethylenbeschichtetes Basispapier eine Empfangsschicht aus Polycarbonat aufgetragen wird. Außerdem wird eine Unterschicht zwischen dem Träger und der Empfangsschicht aufgebracht. Diese Unterschicht besteht aus einem Vinylidenchlorid-Copolymer und dient zur Verbesserung der Haftung der Empfangsschicht auf dem Trägermaterial.From US Pat. Nos. 4,748,150 and 4,774,224 it is known that a polycarbonate receiving layer is applied to a polyethylene-coated base paper. In addition, an underlayer is applied between the support and the receiving layer. This underlayer consists of a vinylidene chloride copolymer and serves to improve the adhesion of the receiving layer to the carrier material.
Nachteilig an diesem Empfangsblatt ist, daß das hier verwendete Polycarbonat stark zur Vergilbung neigt und im Laufe der Zeit das übertragene Bild negativ beeinflußt. Ein weiterer Nachteil liegt darin, daß das Auftragen beider Schichten aus einem Lösungsmittelmilieu geschieht, was Gesundheits- und Sicherheitsprobleme mit sich bringt.A disadvantage of this receiver sheet is that the polycarbonate used here tends to yellow and adversely affect the transferred image over time. Another disadvantage is that both layers are applied from a solvent environment, which poses health and safety problems.
Das Problem der Druckempfindlichkeit des Empfangsblattes beim Kontakt mit dem Heizkopf wird in der europäischen Patentanmeldung EP 0 288 193 behandelt. Die Druckempfindlichkeit äußert sich durch eine Verminderung des Oberflächenglanzes der Schicht oder durch das Phänomen "strike-through", bei dem der Abdruck des Bildes auf der Rückseite des Empfangsblattes zu beobachten ist.
Das Problem wird dadurch gelöst, daß auf ein Polyesterträgermaterial mit einer aufcoextrudierten Polyesterempfangsschicht eine Trennschicht auf Silikonbasis mit einem SiO₂-Zusatz aufgebracht wird. Nachteilig an diesem Empfangsblatt ist, daß wahrscheinlich infolge einer Reaktion zwischen den reaktiven Gruppen der Silikon-Verbindungen und dem in die Empfangsschicht hineindiffundierenden Farbstoff das erhaltene Bild verwischt ist. Außerdem fehlt die auf dem Markt gewünschte Fotoähnlichkeit des auf diese Weise erzeugten Bildes.The problem of the pressure sensitivity of the receiver sheet when it comes into contact with the heating head is dealt with in European patent application EP 0 288 193. The pressure sensitivity is manifested by a reduction in the surface gloss of the layer or by the "strike-through" phenomenon, in which the impression of the image on the back of the receiver sheet can be observed.
The problem is solved in that a release layer on a silicone basis with an SiO₂ additive is applied to a polyester carrier material with a coextruded polyester receiving layer. A disadvantage of this receiving sheet is that the image obtained is probably blurred due to a reaction between the reactive groups of the silicone compounds and the dye diffusing into the receiving layer. In addition, the desired photographic similarity of the image produced in this way is missing on the market.
Es ist weiterhin bekannt, daß die aus dem Donor-Farbband stammenden und in die Empfangsschicht hineindiffundierten Farbstoffe unter Lichteinwirkung zum Verblassen neigen. Dieses Problem wurde in der Patentschrift US 4 775 657 gelöst, indem auf die aus Polycarbonat bestehende Empfangsschicht eine Schutzschicht aus Polyester oder Polyurethan aufgetragen wird. Nachteilig dabei ist die Druckempfindlichkeit des auf diese Weise hergestellten Empfangsblattes, sowie die hierfür erforderlichen mehreren Arbeitsstufen und das Auftragen der Schichten aus organischen Lösungsmitteln.It is also known that the dyes originating from the donor ink ribbon and diffused into the receiving layer tend to fade when exposed to light. This problem was solved in US Pat. No. 4,775,657 by applying a protective layer made of polyester or polyurethane to the polycarbonate receiving layer. The disadvantage here is the pressure sensitivity of the receiver sheet produced in this way, as well as the several work steps required for this and the application of the layers of organic solvents.
In der Patentanmeldung EP 0 261 970 ist eine Empfangsschicht beschrieben, die einen linearen gesättigten Polyester als Bindemittel und ein mit Kieselsäure gekoppeltes Silan-Copolymer als Trennmittel ("anti-blocking"-Zusatz) enthält.Patent application EP 0 261 970 describes a receiving layer which contains a linear saturated polyester as a binder and a silane copolymer coupled with silica as a release agent ("anti-blocking" additive).
Der vorliegenden Erfindung liegt nun die Aufgabe zugrunde, ein Bildempfangsmaterial für thermische Farbstoffübertraungsverfahren vorzuschlagen, das frei von den oben beschriebenen Nachteilen ist, d. h. hitze- und lichtstabil sowie druckunempfindlich ist, eine gute Planlage und gute "anti-blocking"-Eigenschaften aufweist. Außerdem wird mit dem Empfangsmaterial eine weitere Verbesserung der Farbdensität und der Farbabstufung (Gradation) im Vergleich zu den auf dem Markt verfugbaren Empfangsblättern erzielt.The present invention is based on the object of proposing an image-receiving material for thermal dye transfer processes which is free from the disadvantages described above, ie is stable to heat and light and is insensitive to pressure, has good flatness and good "anti-blocking" properties. In addition, the reception material further improves the color density and gradation compared to the reception sheets available on the market.
Diese Aufgabe wird gelöst, indem auf die Vorderseite eines polyolefinbeschichteten Basispapiers eine Empfangsschicht aufgetragen wird, die als farbstoffaufnehmendes Harz eine Kombination aus wenigstens einem, polare Gruppen enthaltenden Acrylat-Copolymer und oxydiertem Polyethylen enthält.This object is achieved in that a receiving layer is applied to the front side of a polyolefin-coated base paper which, as the dye-receiving resin, contains a combination of at least one acrylate copolymer containing polar groups and oxidized polyethylene.
Überrraschend wurde gefunden, daß die Verwendung der o. a. Kombination ein Empfangsblatt schafft, welches nicht nur die anfangs aufgezählten Anforderungen erfüllt, sondern auch eine hohe Farbdensität des übertragenen Bildes ermöglicht bei gleichzeitiger Erhöhung der Gradation.It was surprisingly found that the use of the above. Combination creates a receiving sheet that not only meets the requirements listed at the beginning, but also enables a high color density of the transmitted image while increasing the gradation.
In bevorzugter Ausführung wird ein Acrylat-Copolymer verwendet, dessen polare Gruppen Carboxyl-, metallgebundene Carboxyl- und/oder Nitrilgruppen sind.
Bei den metallgebundenen Carboxylgruppen werden Zink-gebundene Carboxylgruppen besonders bevorzugt.In a preferred embodiment, an acrylate copolymer is used, the polar groups of which are carboxyl, metal-bonded carboxyl and / or nitrile groups.
In the case of the metal-bonded carboxyl groups, zinc-bonded carboxyl groups are particularly preferred.
Am Aufbau des in der erfindungsgemäßen Kombination enthaltenen Acrylat-Copolymers sind Acrylnitril und/oder Methacrylsäure beteiligt, und der Anteil dieser Monomere im Copolymer beträgt in der Summe 10 bis 40 Mol.-%. In einer bevorzugten Ausführung beträgt der Anteil der genannten Monomere 25 bis 35 Mol.-%.Acrylonitrile and / or methacrylic acid are involved in the construction of the acrylate copolymer contained in the combination according to the invention, and the total proportion of these monomers in the copolymer is 10 to 40 mol%. In a preferred embodiment, the proportion of the monomers mentioned is 25 to 35 mol%.
Am Aufbau des Acrylat-Copolymers kann auch zusätzlich Styrol in einer Menge bis 40 Mol.-% beteiligt sein.Up to 40 mol% of styrene can also be involved in the construction of the acrylate copolymer.
Das Gewichtsverhältnis Acrylat-Copolymer/oxydiertes Polyethylen in der erfindungsgemäßen Kombination beträgt 99 : 1 bis 30 : 70. Die Ergebnisse hinsichtlich der Farbdensität und Farbabstufung sind bei einem Gewichtsverhältnis Acrylat-Copolymer/oxydiertes Polyethylen von 70 : 30 bis 40 : 60 am günstigsten (Beispiel 2, Tabelle 2).The weight ratio of acrylate copolymer / oxidized polyethylene in the combination according to the invention is 99: 1 to 30:70. The results with regard to color density and color gradation are most favorable when the weight ratio of acrylate copolymer / oxidized polyethylene is from 70:30 to 40:60 (example 2, Table 2).
Die Empfangsschicht für das erfindungsgemäße Empfangsblatt kann außer dem farbstoffaufnehmenden Harz noch feinteilige Kieselsäure oder Al₂O₃ als Mattierungsmittel sowie weitere Zusätze, wie Netzmittel, z. B. Fluortenside, Dispergierhilfsmittel, Farbkuppler, UV-Stabilisatoren, Pigmente und ähnliche Hilfsstoffe enthalten.The receiving layer for the receiving sheet according to the invention can in addition to the dye-absorbing resin still finely divided silica or Al₂O₃ as a matting agent and other additives such as wetting agents, eg. B. fluorosurfactants, dispersants, color couplers, UV stabilizers, pigments and similar auxiliaries.
Die Empfangsschicht kann mit Hilfe aller gebräuchlichen Auftrags- und Dosierungsverfahren z. B. Walzenauftrags-, Gravur- oder Nipp-Verfahren auf ein Substrat, z. B. PE-beschichtetes Papier aufgebracht werden.The receiving layer can with the help of all common application and dosing procedures such. B. roller application, engraving or nipping process on a substrate, for. B. PE coated paper can be applied.
Die Empfangsschicht kann aus wäßrigem Milieu in einem einzigen Arbeitsgang aufgetragen werden.The receiving layer can be applied from an aqueous medium in a single operation.
Die Auftragsmenge der Empfangsschicht beträgt 0,3 - 15 g/m², vorzugsweise 1 bis 10 g/m².The application amount of the receiving layer is 0.3 - 15 g / m², preferably 1 to 10 g / m².
Als Unterlage wird ein mindestens von einer Seite mit Polyolefin, z. B. Polyethylen beschichtetes Papier bevorzugt, wobei die Polyolefinschicht entsprechend dem Stand der Beschichtungstechnik ein Flächengewicht von 5 g/m² oder mehr, vorzugsweise 7 - 25 g/m² hat.As a base, at least one side with polyolefin, e.g. B. polyethylene coated paper is preferred, the polyolefin layer according to the state of the coating technology has a basis weight of 5 g / m² or more, preferably 7-25 g / m².
