Description

Die Erfindung betrifft ein Werbedisplay, umfassend eine tiefgezogene, transparente Trägerscheibe aus Kunststoff, eine auf die Trägerscheibe zumindest bereichsweise, unter Einwirkung von Druck und Wärme und unter Zwischenschaltung einer Haftschicht, aufgeprägte metallische Prägefolie und mindestens eine zumindest bereichsweise auf der Trägerscheibe und/oder die metallische Prägefolie aufgebrachte Farbschicht.The invention relates to an advertising display, comprising a deep-drawn, transparent carrier disc made of plastic, at least partially on the carrier disk, under the action of pressure and heat and with the interposition of an adhesive layer, embossed metallic embossing foil and at least one area on the support plate and / or the metallic Embossing foil applied paint layer.

Solche Werbedisplays sind im Stand der Technik gut bekannt. So offenbart, beispielsweise, die DE 42 24 463 C1 ein Verfahren zum Beschichten einer transparenten Trägerplatte mit einer metallischen Prägefolienbeschichtung, bei dem in bestimmten Bereichen der Trägerplatte eine Farbschicht aus mindestens einer den an sich durch die Prägefolie bewirkten Farbton der Beschichtung in einen anderen Farbton umwandelnden Farbe angeordnet wird, so daß beispielsweise durch eine Silberfolie und eine gelbe Farbschicht ein Gold-Ton erzeugt werden kann. Aus der DE 44 12 876 C2 ist ferner bekannt, eine zweite Farbschicht zur genaueren Einstellung des Farbtons der Beschichtung der Trägerplatte, sei es durch Farbunterstützung oder Farbumwandlung, zu verwenden.Such advertising displays are well known in the art. Thus, for example, DE 42 24 463 C1 discloses a method for coating a transparent carrier plate with a metallic embossing foil coating, wherein in certain areas of the carrier plate, a color layer of at least one of the embossing foil caused by the color shade of the coating into another hue converting Color is arranged so that, for example, by a silver foil and a yellow color layer, a gold tone can be generated. From DE 44 12 876 C2 is also known to use a second color layer for more accurate adjustment of the hue of the coating of the carrier plate, either by color support or color conversion.

Auch aus der DE 42 40 817 A1 ist eine Trägerplatte bekannt, die bereichsweise mit einer metallischen Prägefolie beschichtet ist, wobei bei einem entsprechenden Herstellungsverfahren zunächst auf die metallisch zu beschichtenden Bereiche ein Heißsiegellack aufgebracht wird, und dann eine mit einer metallfarbig wirkenden Schicht bedampfte Trägerfolie aufgewalzt oder aufgeprägt wird. Die metallfarbige Schicht haftet dabei nur dort, wo der Heißsiegellack aufgebracht wurde, während sich im übrigen die Trägerfolie von der Trägerplatte abziehen läßt. Die Trägerplatte kann anschließend mit anderen Farben bedruckt werden.A support plate is also known from DE 42 40 817 A1, which is partially coated with a metallic embossing film, wherein in a corresponding manufacturing process, first a heat-sealing lacquer is applied to the areas to be coated metallically, and then rolled rolled a coated with a metal-colored layer support film or imprinted. The metal-colored layer adheres only where the heat sealing lacquer was applied, while in the rest, the carrier film can be deducted from the carrier plate. The carrier plate can then be printed with other colors.

Die bekannten Beschichtungsverfahren haben sich zwar grundsätzlich bewährt, jedoch zeigt sich im langfristigen Einsatz der entsprechend beschichteten Trägerplatten in Form von Werbedisplays, die häufig durch Außeninstallation der Witterung ausgesetzt sind, ein Verblassen des metallischen Glanzes. Dies ist darauf zurückzuführen, daß die metallische Farbgebung durch Aluminium und/oder eine Aluminiumlegierung bewirkt wird und es aufgrund einer Oxidation von Aluminium zu einem Aluminiumschwund kommt, so daß der metallische Farbeffekt der Beschichtung mit der Zeit verloren geht. Dabei beruht die Oxidation von Aluminium im wesentlichen darauf, daß Farbschichten, Klebemittel und/oder Bindemittel, die bei den bekannten Werbedisplays verwendet werden, in der Regel Polyvinylchlorid (PVC) zur Einstellung der Flußfähigkeit enthalten, das unter Witterungseinflüssen Chlor abspalten kann, was wiederum eine Oxidation der Aluminiumschicht zur Folge hat.Although the known coating methods have basically proven themselves, however, in the long-term use of the correspondingly coated carrier plates in the form of advertising displays, which are frequently exposed to the weather by outdoor installation, a fading of the metallic luster. This is because the metallic coloring is caused by aluminum and / or an aluminum alloy, and aluminum shrinkage occurs due to oxidation of aluminum, so that the metallic color effect of the coating is lost over time. The oxidation of aluminum is essentially based on the fact that color layers, adhesives and / or binders, which are used in the known advertising displays, usually contain polyvinyl chloride (PVC) to adjust the flowability, which can split off chlorine under atmospheric conditions, which in turn Oxidation of the aluminum layer has the consequence.

Aus der US 4,353,766 ist ferner ein Verfahren zum Herstellen einer Glasplatte bekannt, welche thermisch isolierende und kontrollierbar lichtdurchlässige Eigenschaften aufweist. Auf einer Oberfläche der Glasscheibe wird zu diesem Zwecke eine Schichtstruktur aufgebracht, umfassend eine schützende Lackschicht aus einem Polyesterharz, eine dünne aufgedampfte Aluminiumschicht und eine weitere Lackschicht aus einem acrylischen Nitrozelluloselack. Die beschichtete Glasscheibe gemäß der US 4,353,766 ist frei von Polyvinylchlorid, jedoch fehlt es an einer notwendigen Tiefziehfähigkeit der Glasscheibe sowie an einer notwendigen Heißprägefähigkeit und/oder Siebdruckfähigkeit der Beschichtung, verbunden mit einer Hitzebeständigkeit von bis zu einer Temperatur von etwa 200°C, um als tiefgezogenes, transparentes Werbedisplay verwendet werden zu können.From US 4,353,766 a method for producing a glass plate is also known, which has thermally insulating and controllable light-transmitting properties. For this purpose, a layer structure comprising a protective lacquer layer of a polyester resin, a thin vapor-deposited aluminum layer and a further lacquer layer of an acrylic nitrocellulose lacquer is applied to one surface of the glass pane for this purpose. The coated glass sheet according to US 4,353,766 is free from polyvinyl chloride, but lacks a necessary thermoformability of the glass sheet as well as a necessary hot stampability and / or screen printing capability of the coating, combined with a heat resistance up to a temperature of about 200 ° C, as deep-drawn, transparent advertising display can be used.

Aufgabe der vorliegenden Erfindung ist es daher, das gattungsgemäße Werbedisplay derart weiterzuentwickeln, daß es die Nachteile des Stands der Technik überwindet, insbesondere dauerhaft haltbar einen metallischen Glanz aufweist und eine ausreichende Tiefziehfähigkeit, Heißprägefähigkeit, Siebdruckfähigkeit und/oder Hitzebeständigkeit aufweist.Object of the present invention is therefore to develop the generic advertising display such that it overcomes the disadvantages of the prior art, in particular durable durable has a metallic luster and has sufficient deep drawability, hot stampability, screen printing capability and / or heat resistance.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Werbedisplay, insbesondere die metallische Prägefolie, die Haftschicht sowie die Farbschicht, frei von Polyvinylchlorid (PVC) ist und daß die zumindest eine Farbschicht Zelluloseester-Materialien als Bindemittel umfaßt.This object is achieved in that the advertising display, in particular the metallic stamping film, the adhesive layer and the ink layer, free of polyvinyl chloride (PVC) and that the at least one color layer comprises cellulose ester materials as a binder.

Dabei ist erfindungsgemäß bevorzugt, daß die Trägerscheibe aus Polymethylmethacrylat hergestellt ist.It is preferred according to the invention that the carrier disk is made of polymethylmethacrylate.

Auch kann erfindungsgemäß vorgesehen sein, daß die metallische Prägefolie eine Aluminiumschicht aus Aluminium und/oder zumindest einer Aluminium-Legierung umfaßt.It can also be provided according to the invention that the metallic stamping foil comprises an aluminum layer of aluminum and / or at least one aluminum alloy.

Erfindungsgemäß bevorzugt ist auch, daß die metallische Prägeschicht acrylische Materialien als Bindemittel umfaßt.Also preferred according to the invention is that the metallic embossing layer comprises acrylic materials as a binder.

Eine Ausführungsform der Erfindung ist gekennzeichnet durch eine schwarze Farbschicht, die einen Rußpigmenttyp mit einem pH-Wert in einem Bereich von 6 bis 10, vorzugsweise mit einem pH-Wert von 8, umfaßt.One embodiment of the invention is characterized by a black ink layer comprising a carbon black pigment type having a pH in a range of 6 to 10, preferably at a pH of 8.

Dabei kann auch vorgesehen sein, daß die Rußpigmente von einem Bindemittel, vorzugsweise auf Acryl- oder Zelluloseester-Basis, umhüllt sind.It can also be provided that the carbon black pigments are enveloped by a binder, preferably based on acrylic or cellulose ester.

Das erfindungsgemäße Werbedisplay zeichnet sich ferner durch eine erste Farbschicht zwischen der Trägerscheibe und der Aluminiumschicht aus, wobei die erste Farbschicht vorzugsweise einen gelben Farbton aufweist, um den an sich durch die Aluminiumschicht bewirkten Silber-Ton in einen Gold-Ton umzuwandeln.The advertising display according to the invention is further characterized by a first color layer between the support disk and the aluminum layer, wherein the first color layer preferably has a yellow hue to convert the per se caused by the aluminum layer silver tone into a gold tone.

Auch kann eine zweite Farbschicht auf der der Trägerscheibe abgewandten Seite der Aluminiumschicht, wobei die zweite Farbschicht vorzugsweise entweder den durch die erste Farbschicht und/oder die Aluminiumschicht bewirkten Farbton unterstützt oder in einen anderen Farbton wandelt, vorgesehen sein.A second color layer can also be provided on the side of the aluminum layer facing away from the carrier disk, wherein the second color layer preferably either supports the hue produced by the first color layer and / or the aluminum layer or converts it into another hue.

Das erfindungsgemäße Werbedisplay kann ferner eine dritte Farbschicht, angeordnet auf der zweiten Farbschicht, aufweisen, die vorzugsweise aus einer weißen Deckschicht besteht.The advertising display according to the invention may further comprise a third color layer, disposed on the second color layer, which preferably consists of a white cover layer.

Das erfindungsgemäße Werbedisplay ist gekennzeichnet durch eine Hitzebeständigkeit bis zu einer Temperatur von etwa 200°C.The advertising display according to the invention is characterized by a heat resistance up to a temperature of about 200 ° C.

Schließlich wird erfindungsgemäß auch der Einsatz einer Lichtquelle auf der die Prägefolie tragenden Seite der beschichteten Trägerscheibe vorgeschlagen.Finally, according to the invention, the use of a light source on the side of the coated carrier disk carrying the embossing film is also proposed.

Der Erfindung liegt somit die überraschende Erkenntnis zugrunde, daß die zur Herstellung eines Werbedisplays verwendeten Komponenten frei von Polyvinylchlorid sein müssen, um eine Oxidation des Aluminiums, und damit den Verlust des metallischen Glanzes des Werbedisplays, zu vermeiden. Unter Beibehaltung der notwendigen Verarbeitungsfähigkeiten der Trägerscheibe kann dies erreicht werden, indem insbesondere acrylische und/oder Zelluloseester-Materialien verwendet werden. Eine notwendige Tiefziehfähigkeit, Heißprägefähigkeit und/oder Siebdruckfähigkeit ist somit stets gewährleistet, ebenfalls eine Verarbeitbarkeit des Werbedisplays bis zu einer Temperatur von etwa 200°C. Ferner sind Potentialdifferenzen, die zu einer elektrochemischen Oxidation von Aluminium führen können, dadurch zu vermeiden, daß die in schwarzer Farbe verwendeten Rußpigmente alkalisch gehalten werden, z. B. einen pH-Wert von 8 aufweisen, sowie in ein PVC-freies Bindemittel eingebettet sind.The invention is therefore based on the surprising finding that the components used to produce an advertising display must be free of polyvinyl chloride in order to avoid oxidation of the aluminum, and thus the loss of the metallic sheen of the advertising display. Maintaining the necessary processing capabilities of the carrier disk, this can be achieved by using, in particular, acrylic and / or cellulose ester materials. A necessary thermoformability, hot stampability and / or screen printing capability is thus always guaranteed, also a processability of the advertising display up to a temperature of about 200 ° C. Furthermore, potential differences which can lead to an electrochemical oxidation of aluminum are to be avoided by keeping the carbon black pigments used in black color alkaline, e.g. B. have a pH of 8, and are embedded in a PVC-free binder.

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung, in der ein Ausführungsbeispiel der Erfindung anhand einer schematischen Zeichnung im einzelnen erläutert ist. Die aus einer einzigen Figur bestehende Zeichnung zeigt dabei einen Abschnitt eines erfindungsgemäßen Werbedisplays im Schnitt.Further features and advantages of the invention will become apparent from the following description in which an embodiment of the invention with reference to a schematic drawing is explained in detail. The existing of a single figure drawing shows a section of an advertising display according to the invention in section.

Wie der Figur zu entnehmen ist, umfaßt ein erfindungsgemäßes Werbedisplay 1 eine Trägerscheibe 2, beispielsweise aus Polymethylmethacrylat, einer Haftschicht 3, eine Farbschicht 4, insbesondere mit einem gelben Farbton, eine Aluminiumschicht 5, sowie eine zweite Farbschicht 6 und eine bevorzugt weiße Deckschicht 7.As can be seen from the figure, an advertising display 1 according to the invention comprises a carrier disk 2, for example made of polymethyl methacrylate, an adhesive layer 3, a color layer 4, in particular with a yellow hue, an aluminum layer 5, and a second color layer 6 and a preferably white top layer 7.

Ein in der Figur dargestelltes Werbedisplay 1 läßt sich unter Einsatz einer nicht gezeigten Konterprägefolie herstellen, die auf einer nicht gezeigten Trägerfolie eine Trennschicht, auf der Trennschicht die aufgedampfte Aluminiumschicht 5, auf der Aluminiumschicht 5 die gelbe Farbschicht 4, und schließlich auf der Farbschicht 4 die Haftschicht 3 aufweist. Diese Konterprägefolie wird mit ihrer Haftschicht 3 auf die Trägerscheibe 2 aufgelegt, wobei nach Einwirkung von Druck und Wärme bei einem Prägevorgang die Trägerfolie samt Trennschicht schließlich abziehbar ist, so daß das in der Figur dargestellte Werbeelement 1 entsteht.An illustrated in the figure advertising display 1 can be produced using a not shown Konterprägefolie on a support film, not shown, a release layer, on the release layer, the vapor-deposited aluminum layer 5, on the aluminum layer 5, the yellow ink layer 4, and finally on the ink layer 4 the Adhesive layer 3 has. These Counter-embossing film is placed with its adhesive layer 3 on the support plate 2, wherein after exposure to pressure and heat during an embossing process, the carrier film including release layer is finally removable, so that the advertising element 1 shown in the figure arises.

Von besonderer Bedeutung bei der Herstellung eines erfindungsgemäßen Werbedisplays 1 ist, daß insbesondere die Aluminiumschicht 5 keinen Kontakt zu PVC-haltigen Materialien aufweist, um eine Oxidation des Aluminiums aufgrund der Abspaltung von Chlor aus dem PVC zu verhindern. Bei Verwendung von acrylischen Materialien in der metallischen Prägefolie und in Klebe- und Bindemitteln in der Haftschicht 3 sowie von Zelluloseestern in den Farbschichten 4, 6 und 7 wird zum einen der Einsatz von PVC vermieden, zum anderen eine notwendige Tiefziehfähigkeit, Heißprägefähigkeit, Siebdruckfähigkeit und Hitzebeständigkeit des Werbedisplays sichergestellt.Of particular importance in the production of an advertising display 1 according to the invention is that in particular the aluminum layer 5 has no contact with PVC-containing materials in order to prevent oxidation of the aluminum due to the elimination of chlorine from the PVC. When using acrylic materials in the metallic stamping foil and in adhesives and binders in the adhesive layer 3 and cellulose esters in the color layers 4, 6 and 7, on the one hand, the use of PVC is avoided, on the other hand a necessary thermoformability, hot stampability, screen printability and heat resistance of the advertising display.

Wird für eine Farbschicht ein schwarzer Farbton benötigt, der in der Regel durch die Verwendung von Rußpigmenten erzielt wird, die von Bindemitteln umhüllt sind, wird bevorzugt ein Rußpigment in einem PVC-freien Bindemittel mit einem pH-Wert in einem Bereich von 6 bis 10, bevorzugt einem pH-Wert von 8, eingesetzt, um elektrische Spannungsdifferenzen im Werbedisplay im wesentlichen zu vermeiden.If a black color is required for a color layer, which is usually achieved by the use of carbon black pigments coated with binders, it is preferred to use a carbon black pigment in a PVC-free binder having a pH in the range from 6 to 10, preferably a pH of 8, used to substantially avoid electrical voltage differences in the advertising display.

Auch wird durch das erfindungsgemäße Werbedisplay die Bildung von Haarrissen vermieden, was das Eindringen von Wasser und somit ebenfalls die Oxidation des Aluminiums ermöglichen würde.Also, the formation of hairline cracks is avoided by the advertising display according to the invention, which would allow the penetration of water and thus also the oxidation of the aluminum.

Ein erfindungsgemäßes Werbedisplay 1 wird vorzugsweise derart verwendet, daß ein Betrachter auf die nichtbeschichtete Seite der Trägerscheibe 2 schaut, so daß bei Tageslicht eine reine Draufsicht auf die Beschichtung vorliegt, während bei Nacht auf der dem Betrachter abgewandten Seite des Werbedisplays 1 eine nicht dargestellte Lichtquelle angeordnet ist, so daß dann eine Durchsicht durch die Beschichtung stattfindet. Sowohl in Draufsicht als auch in Durchsicht weist das erfindungsgemäße Werbedisplay 1 einen metallischen Ton auf, wobei der entsprechende Farbton durch die Farbschicht 4 einstellbar ist. Aufgrund des Verzichts von Polyvinylchlorid in dem erfindungsgemäßen Werbedisplay 1 ist ein langzeitiger Metallglanz des Werbedisplays 1 sichergestellt.An inventive advertising display 1 is preferably used so that a viewer looks at the uncoated side of the support plate 2, so that there is a pure plan view of the coating in daylight, while at night on the side facing away from the viewer of the advertising display 1 arranged a light source, not shown is, so that then takes a look through the coating. Both in plan view and in transparency, the advertising display 1 according to the invention has a metallic tone, wherein the corresponding hue is adjustable by the ink layer 4. Due to the omission of polyvinyl chloride in the advertising display 1 according to the invention, a long-term metallic gloss of the advertising display 1 is ensured.
