Description

Die Erfindung betrifft ein Aufzeichnungsmaterial für das Tintenstrahl-Druckverfahren (Ink-Jet-Verfahren).The invention relates to a recording material for the Ink jet printing process (ink jet process).

Das Ink-Jet-Verfahren gehört zu den elektronischen Druckverfahren. Hierbei ist es möglich, Bilder, Texte und Graphiken am Rechner zusammenzusetzen und als Bildschirmhardcopy direkt auszudrucken.The ink jet process is one of the electronic ones Printing process. Here it is possible to add pictures, texts and Compose graphics on the computer and as Print out the screen hardcopy directly.

Beim Ink-Jet-Verfahren werden Tröpfchen einer Aufzeichnungsflüssigkeit auf die Oberfläche des Trägermaterials mittels unterschiedlicher Techniken aufgetragen. Zur Tropfenerzeugung gibt es grundsätzlich zwei Verfahrensvarianten.
Bei der Methode der kontinuierlichen Tropfenerzeugung wird unter Hochdruck ein permanenter Tröpfchenstrom aus der Düse getrieben. Die nicht für den Bildaufbau benötigten Tropfen werden durch verschiedene Prinzipien wieder dem Tintenvorratsbehälter zugeführt.In the ink jet process, droplets of a recording liquid are applied to the surface of the carrier material using various techniques. There are basically two process variants for drop generation.
With the method of continuous drop generation, a permanent stream of droplets is driven out of the nozzle under high pressure. The drops that are not required for image formation are fed back into the ink reservoir by various principles.

Bei der DropOn-Demand Methode wird nur an den zu bebildernden Stellen auf Abruf ein Tintentröpfchen erzeugt. Durch eine digitale elektronische Steuerung, wie bei dem Hertz Verfahren, ist es möglich, Bilder mit sehr hoher Auflösung direkt aus elektronischen Daten zu erzeugen.With the DropOn-Demand method, only the images to be imaged Make an ink droplet on demand. By a digital electronic control, like the Hertz process, it is possible to take pictures with very high resolution directly to generate electronic data.

Das Ink-Jet-Aufzeichnungsverfahren wird zur Herstellung von Farbgraphiken, Vollfarbkopien und auch für Textdrucke eingesetzt, es umfaßt also ein sehr breites Anwendungsfeld.
An das Aufzeichnungsmaterial werden unterschiedliche Anforderungen gestellt wie Printglanz, Farbverlaufen (Bleed), Farbdensität, Trocknungsverhalten, Unruhe (Mottle), Abklatschen und Glanz. The ink jet recording process is used for the production of color graphics, full color copies and also for text printing, so it covers a very wide field of application.
Different requirements are placed on the recording material, such as print gloss, color bleeding, color density, drying behavior, agitation (mottle), clapping and gloss.

Das Empfangsmaterial besteht im allgemeinen aus einem Trägermaterial, einer Tintenempfangsschicht und gegebenenfalls weiteren Hilfsschichten.The receiving material generally consists of a Carrier material, an ink receiving layer and optionally further auxiliary layers.

Die DE 37 07 627 beschreibt eine Tintenaufnahmeschicht, die aus zwei Polymereinheiten mit einer quaternären Ammoniumverbindung und einem Pigment besteht. Dadurch erreicht man eine hohe Farbdichte, gute Tintenabsorption und eine gute Wasserbeständigkeit. Durch den hohen Pigmentanteil wird aber der Glanz so stark reduziert, daß er sich auch durch eine Kalandrierung nicht wesentlich erhöhen läßt. Bedingt durch das verwendete Papier, ist auch mit einem Absinken der Tintenaufnahmeschicht zu rechnen.DE 37 07 627 describes an ink receiving layer which from two polymer units with a quaternary Ammonium compound and a pigment. Thereby achieved one has high color density, good ink absorption and good Water resistance. Due to the high pigment content the gloss is reduced so much that it can also be replaced by a Calendering can not be increased significantly. Due to that paper used, is also with a drop in Ink absorption layer to be expected.

Die JP 01-009776 und die JP 01-075281 beschreiben eine Tintenaufnahmeschicht mit gutem Kontrast, guter Licht- und Wasserbeständigkeit, die aus einem Copolymer und einem Bindemittel/Pigmentgemisch besteht. Das Copolymer setzt sich zusammen aus einem Dimethyldiallylammoniumchlorid und einem Acrylamid. Auch hier kommt es durch den Pigmentanteil zu einem Glanzverlust.JP 01-009776 and JP 01-075281 describe one Ink receiving layer with good contrast, good light and Water resistance consisting of a copolymer and a Binder / pigment mixture exists. The copolymer settles together from a dimethyldiallylammonium chloride and a Acrylamide. Here too there is a pigment content Loss of gloss.

Die DE 43 22 178 schlägt zur Erreichung von hoher Farbdichte und Bildschärfe eine pigmenthaltige Tintenaufnahmeschicht vor, die ebenfalls eine quaternäre Ammoniumverbindung enthält.
Wie bei den oben angeführten Schriften wird auch hier die Retention der Farbstoffe aus der Tinte durch die Zugabe des Pigments erreicht und ist mit einer Glanzminderung verbunden.DE 43 22 178 proposes a pigment-containing ink-receiving layer which also contains a quaternary ammonium compound in order to achieve high color density and sharpness.
As with the documents mentioned above, the retention of the dyes from the ink is achieved by adding the pigment and is associated with a reduction in gloss.

Die EP 0 627 324 beschreibt ein Aufzeichnungsmaterial für das Tintenstrahldruckverfahren, bei dem in der Empfangsschicht ein Terpolymer einer quaternären Ammoniumverbindung eingesetzt wird. Zusätzlich wird ein Epoxid oder ein Triazin als Vernetzungsmittel zugegeben. Dadurch wird ein Auslaufen der Farbpunkte und eine Ungleichmäßigkeit der Farbe und der Densität verhindert. Nachteilig ist aber eine Verlängerung der Trockenzeit und eine schlechtere Farbaufnahme. Durch Einpolymerisieren der quaternären Ammoniumverbindung in das Terpolymer vermindert sich die Steuerungsmöglichkeit für die Optimierung der Farbfixierung.EP 0 627 324 describes a recording material for the Inkjet printing process, in which in the receiving layer Terpolymer of a quaternary ammonium compound used becomes. In addition, an epoxy or a triazine is considered Crosslinking agent added. This will cause the Color dots and an unevenness of color and Density prevented. The disadvantage is an extension of the Drying time and poorer color absorption. By Polymerizing the quaternary ammonium compound into the Terpolymer reduces the ability to control the Optimization of color fixation.

Die DE 43 22 178 beschreibt ein Aufzeichnungsmaterial für das Ink-Jet-Druckverfahren einem geleimten Rohpapier als Trägermaterial. Nachteilig daran ist ein Auftreten von Glanzunterschieden bei dem bedrucktem Material.DE 43 22 178 describes a recording material for the Ink jet printing process as a glued base paper Backing material. The disadvantage of this is the occurrence of Differences in gloss in the printed material.

Aufgabe der Erfindung ist es, ein Aufzeichnungsmaterial für das Ink-Jet-Druckverfahren zur Verfügung zu stellen, das sich durch hohe Farbdichte, hohen Glanz, gute Trocknungseigenschaften, hohe Farbbrillanz und geringes Farbverlaufen bei niedrigem Auftragsgewicht der Empfangsschicht auszeichnet.The object of the invention is to provide a recording material for to provide the ink jet printing process that is due to high color density, high gloss, good Drying properties, high color brilliance and low Color gradients with low weight of the Distinguished reception layer.

Diese Aufgabe wird durch ein Aufzeichnungsmaterial gelöst, das einen Träger und eine darauf angeordnete Tintenaufnahmeschicht enthält, die ein unvernetztes Copolymer, bestehend aus einer quaternären Ammoniumverbindung und Vinylpyrrolidon, einen Polyvinylalkohol und ein Aminomethacrylat-Copolymer enthält.This problem is solved by a recording material which a support and an ink-receiving layer disposed thereon contains an uncrosslinked copolymer consisting of a quaternary ammonium compound and vinyl pyrrolidone, one Contains polyvinyl alcohol and an aminomethacrylate copolymer.

Zur besseren Farbstoffixierung und Verbesserung der Trocknungseigenschaften wird ein hydroxyfunktionelles, quaternäres, Aminogruppen enthaltendes Polymer auf Basis von Alkyl(meth)acrylsäureester oder Alkyl(meth)acrylamid und einem Polyvinylalkohol als weiterem Bindemittel eingesetzt.
Geeignet sind teilverseifte und vollverseifte Polyvinylalkohole. To improve dye fixation and improve the drying properties, a hydroxy-functional, quaternary, amino-containing polymer based on alkyl (meth) acrylic acid ester or alkyl (meth) acrylamide and a polyvinyl alcohol is used as a further binder.
Partially saponified and fully saponified polyvinyl alcohols are suitable.

Weitere Bestandteile der Tintenaufnahmeschicht können Polyvinylpyrrolidon(PVP)-Homopolymere, farbstoffixierende Mittel, optische Aufheller, Farbstoffe und andere Hilfsstoffe sein.Other components of the ink receiving layer can Polyvinylpyrrolidone (PVP) homopolymers, dye-fixing Agents, optical brighteners, dyes and other auxiliaries be.

Da sich das Trägermaterial in den Glanzwerten je nach Anfertigung unterscheiden kann, ist es in einigen Fällen nötig, Pigmente der Tintenaufnahmeschicht hinzufügen, die eine Einstellung des Glanzes ermöglichen. Zur Steuerung des Glanzes können Pigmente wie Calciumcarbonat, Titandioxid, Clay, Siliciumdioxid, Bentonit, Aluminiumoxid oder Böhmit zugesetzt werden. Die Menge der Pigmente in der Tintenaufnahmeschicht kann 0 und 5 Gew.%, bezogen auf die getrocknete Schicht betragen.Since the carrier material varies in gloss values depending on Manufacturing may differ, in some cases necessary to add pigments to the ink-receiving layer, the one Allow adjustment of the gloss. To control the shine pigments such as calcium carbonate, titanium dioxide, clay, Silicon dioxide, bentonite, aluminum oxide or boehmite added will. The amount of pigments in the ink-receiving layer can be 0 and 5% by weight, based on the dried layer be.

Der gewichtsmäßige Anteil des Copolymers an der Tintenaufnahmeschicht kann 5 bis 80% Gew.% und in einer bevorzugteren Form 15 bis 50 Gew.% betragen.
Der Anteil des hydroxyfunktionellen, Aminogruppen enthaltenden Polymers liegt vorzugsweise bei 5 bis 75 Gew.% und in einer noch bevorzugteren Ausführungsform bei 15 bis 50 Gew.%. Der Anteil des Polyvinylalkohols kann 5 bis 80 Gew.% und gemäß einer noch bevorzugteren Ausführungsform bei 30 bis 60 Gew.%.The proportion by weight of the copolymer in the ink-receiving layer can be 5 to 80% by weight and, in a more preferred form, 15 to 50% by weight.
The proportion of the hydroxy-functional polymer containing amino groups is preferably 5 to 75% by weight and in a more preferred embodiment 15 to 50% by weight. The proportion of the polyvinyl alcohol can be 5 to 80% by weight and, according to an even more preferred embodiment, 30 to 60% by weight.

Das Auftragsgewicht der getrockneten Empfangsschicht kann 2 bis 15g/m2 und vorzugsweise 4 bis 10g/m2 betragen. The coating weight of the dried receiving layer may be 2 to 15 g / m 2 and preferably 4 to 10 g / m 2, respectively.

Die wässrige Beschichtungsmasse kann in folgenden Gewichtsmengen variieren: Gew. % Vinylpyrrolidon/Methacrylamidopropyltrimethylammoniumchlorid Copolymer 2,2 - 60 ,0 Aminomethacrylat 2,2 - 57,0 Polyvinylalkohol 3,0 - 80,0 Hilfsstoffe 0,0 - 20,0 Wasser Rest bis 100,0 The aqueous coating composition can vary in the following amounts by weight: % By weight Vinyl pyrrolidone / methacrylamidopropyl trimethyl ammonium chloride copolymer 2.2 - 60.0 Aminomethacrylate 2.2 - 57.0 Polyvinyl alcohol 3.0 - 80.0 Auxiliaries 0.0 - 20.0 water Rest up to 100.0

Die Beschichtungsmase zur Herstellung der erfindungsgemäßen Tintenaufnahmeschicht kann mit allen gebräuchlichen Auftrags- und Dosierverfahren, wie Walzenauftrag-, Gravur- oder Nipp-Verfahren und Luftbürsten oder Rollrakeldosierung aufgetragen werden.The coating phase for the production of the invention Ink receiving layer can be used with all common application and Dosing processes, such as roller application, engraving or nipping processes and air brushes or roller doctor dosage applied will.

In einer besonderen Ausgestaltung wird zwischen dem Trägermaterial und der Empfangsschicht zusätzlich eine Zwischenschicht aufgetragen. Die Zwischenschicht enthält vorzugsweise Polyvinylalkohol; es eignen sich aber auch Verbindungen wie Polyvinylpyrrolidon oder Polyvinylacetat oder deren Gemische. Durch diese Zwischenschicht erzielt man einen hohen Printglanz, da ein Absinken der Empfangsschicht bei Papieren ohne Kunstharzbeschichtung verhindert wird.
Da die Oberfläche von Papier immer eine gewisse Porosität aufweist, werden Teile der Beschichtungen von dem Papier aufgenommen.In a special embodiment, an intermediate layer is additionally applied between the carrier material and the receiving layer. The intermediate layer preferably contains polyvinyl alcohol; but compounds such as polyvinylpyrrolidone or polyvinyl acetate or mixtures thereof are also suitable. This intermediate layer achieves a high print gloss, since the receiving layer on papers without synthetic resin coating is prevented from sinking.
Since the surface of paper always has a certain porosity, parts of the coatings are absorbed by the paper.

Der Printglanz wird am bedruckten Papier, besonders bei dunklen Flächen sichtbar und sollte über die gesamte Fläche einheitlich sein. Hoher Printglanz äußert sich in einer glatten glänzenden Schicht. Bei Papieren, die mit Kunstharz beschichtet sind, wird durch diese Zwischenschicht die Haftung der Empfangsschicht am Trägermaterial verbessert, ein Aufschieben der Empfangsschicht im Drucker wird so verhindert.
Das Auftragsgewicht der getrockneten Zwischenschicht kann 0,1 bis 4,0g/m2, vorzugsweise 0,5 bis 2,0g/m2 betragen.The print gloss is visible on the printed paper, especially in dark areas and should be uniform over the entire area. High print gloss manifests itself in a smooth, shiny layer. In the case of papers coated with synthetic resin, this intermediate layer improves the adhesion of the receiving layer to the carrier material, preventing the receiving layer from being pushed open in the printer.
The application weight of the dried intermediate layer can be 0.1 to 4.0 g / m 2 , preferably 0.5 to 2.0 g / m 2 .

Als Trägermaterialien eignen sich bevorzugt Papiere, die beidseitig mit Kunstharz beschichtet sind und sogenannte gießbeschichtete (castcoatet) Papiere. Als besonders wichtig hat sich dabei eine sehr glatte, gleichmäßige Oberfläche erwiesen. Die Oberflächenrauhigkeit (Ra) nach DIN 4768 darf einen Wert von 0,8µm bei einer Meßstrecke von 5mm nicht überschreiten.Suitable carrier materials are preferably papers which are coated on both sides with synthetic resin and so-called cast-coated papers. As particularly important has a very smooth, even surface proven. The surface roughness (Ra) according to DIN 4768 may a value of 0.8µm with a measuring distance of 5mm not exceed.

Die beidseitig mit Kunstharz beschichteten Papiere haben ein Flächengewicht von 50 bis 250 g/m2. Als Kunstharz werden beispielsweise Polyolefine oder Polyester eingesetzt.
Die Auftragsmenge der Kunstharzbeschichtung beträgt mindestens 5 g/m2. Es können zusätzlich noch Pigmente, Farbstoffe und andere Hilfsstoffe in dieser Beschichtung enthalten sein.The papers coated on both sides with synthetic resin have a basis weight of 50 to 250 g / m 2 . Polyolefins or polyester, for example, are used as the synthetic resin.
The application quantity of the synthetic resin coating is at least 5 g / m 2 . Pigments, dyes and other auxiliaries can also be contained in this coating.

Weiterhin hat sich gießbeschichtetes Papier als besonders geeignet erwiesen. Diese Papiere werden in der Papiermaschine mit einem dünnen Bindemittel und Pigment enthaltenden Oberflächenstrich versehen und unter Druck gegen eine heiße Hochglanztrommel gedrückt. Dadurch erhält man Papiere mit einer guten, glänzenden Oberfläche, die die Nachteile von hochkalanderten Papieren nicht zeigen. Gegenüber kunstharzbeschichteten Papieren hat dies den Vorteil sehr niedriger Trockenzeiten. Das Flächengewicht liegt bei diesem Papier zwischen 50 g/m2 und 270 g/m2. Der Glanz des Papiers mit Zwischenschicht, gemessen bei 600, darf nicht kleiner als 80% sein, da sich der Glanz des Basispapiers, bedingt durch das geringe Auftragsgewicht der Tintenaufnahmeschicht, stark auf das fertige Aufzeichnungsmaterial auswirkt. Der Printglanz muß bei Papieren ohne Zwischenschicht mindestens 65%, mit Zwischenschicht mindestens 75% betragen.Cast-coated paper has also proven to be particularly suitable. These papers are coated in the paper machine with a thin coating of binder and pigment and pressed under pressure against a hot high-gloss drum. This gives papers with a good, glossy surface that do not show the disadvantages of highly calendered papers. Compared to synthetic resin coated papers, this has the advantage of very low drying times. The basis weight for this paper is between 50 g / m 2 and 270 g / m 2 . The gloss of the paper with an intermediate layer, measured at 60 ° , must not be less than 80%, since the gloss of the base paper, due to the low application weight of the ink-receiving layer, has a strong effect on the finished recording material. The print gloss must be at least 65% for papers without an intermediate layer and at least 75% with an intermediate layer.

Als Trägermaterial geeignet ist aber auch ein unbeschichtetes oder gestrichenes Basispapier.An uncoated material is also suitable as a carrier material or coated base paper.

Die nachfolgenden Beispiele sollen die Erfindung näher erläutern.The following examples are intended to illustrate the invention explain.
