Description

Die Erfindung betrifft ein Transferetikett, mit einer Trägermaterialschicht, einer lösbar auf der Trägermaterialschicht angeordneten, mittels Klebstoff auf einem Gegenstand befestigbaren Aufdruckschicht und einer zwischen der Trägermaterialschicht und der Aufdruckschicht angeordneten, von der Trägermaterialschicht lösbaren Schutzschicht.The invention relates to a transfer label, with a carrier material layer, one detachable on the carrier material layer arranged, attachable to an object by means of adhesive Imprint layer and one between the carrier material layer and the print layer arranged from the Carrier material layer removable protective layer.

Ein Etikett dieser Art ist aus der W090/05088 bekannt. Dort ist zwischen einem hochglanzbeschichteten Trägermaterial und den auf das Substrat zu übertragenden Schichten eine Trennmaterialschicht vorgesehen, welche bei der Übertragung des Etiketts auf den Gegenstand durch Wärme derart aktiviert wird, daß sie die Ablösung der zu übertragenden Schichten von dem Trägermaterial ermöglicht. Fehlt diese Trennmaterialschicht, läßt sich das Trägermaterial nicht von dem noch erwärmten Etikett abziehen. Nach dem Übertragen des Etiketts auf den Gegenstand wird eine zusätzliche Schutzschicht aufgebracht, und anschließend wird diese unter UV-Bestrahlung gehärtet. Dieser Nachhärteprozeß erfordert eine relativ lange Laufstrecke und ist maschinell aufwendig. Dies gilt insbesondere, wenn es sich bei den Gegenständen um Getränkeglasflaschen handelt, die zur Reibungsminderung in Drängelstrecken von Flaschenfüllanlagen mit einer Kunststoffschicht überzogen sind, welche bei der UV-Bestrahlung zu schonen ist.A label of this type is known from W090 / 05088. There is between a high gloss coated substrate and a layer of release material for the layers to be transferred to the substrate provided which in the transfer of the Labels on the item are activated by heat in this way is that they detach the layers to be transferred from the carrier material. If this separating material layer is missing, the carrier material can not be from the still heated Peel off the label. After transferring the label an additional protective layer is applied to the object, and then it is hardened under UV radiation. This post-curing process takes a relatively long time Running distance and is mechanically complex. This is especially true if the items are beverage glass bottles acts to reduce friction in crowded areas of bottle filling systems covered with a plastic layer which are to be spared with UV radiation.

Aus der US-4 529 624 ist ein Transferetikett bekannt, dessen Außenschicht über eine bei der Übertragung zu schmelzende, Paraffinschicht mit dem Trägermaterial verbunden ist. Die Paraffinschicht bleibt nach der Übertragung auf dem Etikett, wobei eventuell Reste auf dem Träger bleiben. Die Übertragung ist daher nicht immer vollständig. A transfer label is known from US Pat. No. 4,529,624 Outer layer over a meltable during transmission Paraffin layer is connected to the carrier material. The Paraffin layer remains on the label after transfer, residues may remain on the carrier. The transfer is therefore not always complete.

Die Paraffinschicht wird durch nachträgliche Beflammung geglättet und dadurch transparenter und glänzender und weniger sichtbar.The paraffin layer is smoothed by subsequent flame treatment and therefore more transparent and shiny and less visible.

Aufgabe der Erfindung ist es daher, ein Transferetikett anzugeben, das rückstandsfrei auf einen Gegenstand überführbar ist und ohne Nachbehandlung auskommt.The object of the invention is therefore to provide a transfer label, that can be transferred without residue to an object is and does not require after-treatment.

Zur Lösung der Aufgabe wird ein Transferetikett der genannten Art vorgeschlagen, bei dem die Schutzschicht als im wesentlichen nicht plastifizierbarer, durch Adhäsion an der Trägermaterialschicht direkt haftender, jedoch im wesentlichen unabhängig von der Temperatur des Etiketts lösbarer, aus einem durchpolymerisierten Material bestehender Schutzfilm ausgebildet ist.To solve the problem, a transfer label of the named Kind proposed in which the protective layer as essentially not plasticizable, due to adhesion to the substrate layer more direct, but essentially independent detachable from the temperature of the label, from one through-polymerized material existing protective film is.

Hierdurch erübrigt sich eine durch Wärmeeinwirkung lösbare Verbindungsschicht zwischen Schutzfilm und Trägermaterial, so daß nach dem Übertragen des Etiketts auf den Gegenstand keine Trennmaterial- oder Wachsschichten auf dem Etikett verbleiben können. Weil der kratzfeste Schutzfilm bereits Teil des Etiketts ist, erübrigt sich das zusätzliche Aufbringen einer Schutzschicht auf das auf dem Gegenstand haftende Etikett. Das Etikett ist in einem Durchgang im "in-line"-Betrieb herstellbar. Das Abziehen der Trägermaterialschicht kurz vor oder während oder kurz nach dem Aufkleben des Etiketts auf den Gegenstand ist unabhängig von der Temperatur des Etiketts. Handelt es sich bei dem Klebstoff um einen thermoaktivierbaren Klebstoff und wird das Etikett unter Erwärmung auf einen entsprechend erwärmten Gegenstand aufgetragen, läßt sich das Trägermaterial sofort abziehen. Den gleichen Vorteil erhält man bei einem kalt zu übertragenden Etikett.This makes a heat-releasable superfluous Connection layer between protective film and carrier material, see above that after transferring the label to the object none Separating material or wax layers remain on the label can. Because the scratch-resistant protective film is already part of the label is, the additional application of one is unnecessary Protective layer on the label stuck on the object. The label can be produced in one pass in "in-line" mode. Pulling off the backing layer just before or during or shortly after sticking on the label the item is independent of the temperature of the label. If the adhesive is a thermo-activatable one Glue and the label is heated on applied an appropriately heated object, leaves peel off the backing immediately. The same advantage is obtained from a label to be transferred cold.

Wegen des Fehlens der Trennmaterialschicht läßt sich ein besonders präziser Druck der Farbschichten erzielen. Die Trennebene zwischen Trägermaterial und Schutzfilm ist besonders genau definiert, so daß sich das Etikett gezielt vom Trägermaterial ablösen und glatt applizieren läßt. Die Wechselwirkung der aneinanderliegenden Oberflächen von Schutzfilm und Trägermaterial begründet sich in Adhäsionskräften, etwa elektrostatischen Kräften. Nach Trennung des Etiketts von dem Trägermaterial und Übertragung auf den Gegenstand bleibt nun die freiliegende Oberfläche des Schutzfilms temperaturunabhängig nicht-klebend. Der Schutzfilm ist hart und kratzunempfindlich.Because of the lack of the separating material layer, a special one can achieve precise printing of the color layers. The parting line between carrier material and protective film is special precisely defined, so that the label is targeted from the carrier material peel off and apply smoothly. The interaction the adjoining surfaces of protective film and Backing material is based on adhesive forces, such as electrostatic Powers. After separating the label from the Backing material and transfer to the object now remains the exposed surface of the protective film is independent of temperature not adhesive. The protective film is hard and scratch-resistant.

Bevorzugt bilden die Trägermaterialschicht und der Schutzfilm eine Materialpaarung mit im wesentlichen temperaturunabhängig vorbestimmter Haltekraft. Die Trägermaterialschicht kann aus mehreren Teilschichten bestehen. Bevorzugt besteht die Trägermaterialschicht zumindest auf der dem Schutzfilm zugewandten Seite aus Polypropylen, dessen den Schutzfilm tragende Seite bevorzugt unvorbehandelt ist. Die Dicke des Trägermaterials kann 20 bis 100 µm betragen, bevorzugt 35 bis 60 µm. Damit sich der Verbund von Trägermaterialschicht und Transferetiketten leicht von einer Rolle abwickeln läßt, kann die vom Schutzfilm abweisende Seite der Trägermaterialschicht haftabweisend ausgestattet sein, etwa silikonisiert oder mit Trennlack versehen sein.The carrier material layer and the protective film preferably form a material pairing with essentially temperature-independent predetermined holding force. The carrier material layer can be made of consist of several sub-layers. The carrier material layer is preferably present at least on the one facing the protective film Polypropylene side, the protective film Side is preferably untreated. The thickness of the substrate can be 20 to 100 microns, preferably 35 to 60 microns. So that the combination of carrier material layer and transfer labels can easily unwind from a roll, the side of the carrier material layer that repels the protective film have a non-stick finish, such as siliconized or Separating varnish.

Bevorzugt ist der Schutzfilm aus unter Bestrahlung aushärtendem Lack, insbesondere kationisch kalt-vernetztem, unter Ultraviolett-Licht aushärtendem Lack gebildet. Kalt-vernetzender kationischer UV-Lack härtet unter UV-Bestrahlung kalt aus. Die Kettenreaktion beginnt durch UV-Anstoß. Die Vernetzung und das Aushärten vollziehen sich vollständig auch ohne weitere UV-Einwirkung. Der Schutzfilm bleibt nach dem Aushärten nicht-klebrig.The protective film is preferably made of radiation curing Lacquer, especially cationically cold-crosslinked, under ultraviolet light curing lacquer formed. Cold-curing Cationic UV varnish hardens under UV radiation out. The chain reaction begins with UV light. The networking and curing takes place completely without further UV exposure. The protective film remains after curing non-sticky.

Alternativ kann man auch einen radikalischen UV-Lack verwenden, der so lange durchhärtet, solange UV-Strahlen auf ihn einwirken. Bei nicht vollständiger Bestrahlung kann jedoch der Lack manchmal klebrig bleiben, so daß die nächste Schicht im Etikettenverbund nicht richtig auf- dem Schutzfilm haftet und es zu Hautbildung kommt (sog. Skinning).Alternatively, you can also use a radical UV varnish, that hardens as long as long as UV rays on it act. In the case of incomplete radiation, however the paint sometimes remains sticky, leaving the next layer does not adhere properly to the protective film in the label assembly and there is skin formation (so-called skinning).

In Frage kommt auch ein durch Elektronenstrahlen aushärtender Lack.An electron beam hardener is also an option Paint.

Der verwendete Lack soll wärmestabil sein, so daß er seine Eigenschaften unter dem Einfluß der Wärmeapplikation bei der Übertragung nicht ändert. Der Schutzfilm besteht aus ungeharzten, nicht-klebrigen Lacken.The paint used should be heat stable so that it is Properties under the influence of heat application in the Transmission does not change. The protective film consists of non-sticky paints.

Der Schutzfilm ist dünner als die Trägermaterialschicht, bevorzugt um den Faktor 2 bis Faktor 100, besonders bevorzugt 10 bis 20. Bevorzugt ist der Schutzfilm 1 bis 10 µm dick, besonders bevorzugt 2,5 bis 5 µm. Je dünner der Schutzfilm ist, desto geringer ist die zur Etikettenübertragung erforderliche Wärmeenergie und desto geringer ist die Wärmebelastung des Gegenstands. Dies ist von besonderem Belang, wenn es sich beim Gegenstand um eine mit Kunststoff gleitgünstig beschichtete Getränkeglasflasche handelt.The protective film is thinner than the carrier material layer, preferred by a factor of 2 to a factor of 100, particularly preferred 10 to 20. The protective film is preferably 1 to 10 μm thick, particularly preferably 2.5 to 5 μm. The thinner the protective film the lower the label transfer required Thermal energy and the lower the thermal load of the object. This is of particular concern, though the object is a slide with plastic coated beverage glass bottle.

Zur Aufnahme von Distorsionen sowie Quetsch- und Zugbelastungen beim Übertragen des Etiketts auf den Gegenstand kann der Schutzfilm dehnbar sein, mit einer Reißdehnung im Bereich von etwa 50 - 400 %, bevorzugt von etwa 100 - 300 %, bevorzugt 150 - 250 %, bevorzugt ca. 200 %.For absorbing distortions as well as crushing and tensile loads when transferring the label to the object, the Protective film can be stretched, with an elongation at break in the range of about 50-400%, preferably about 100-300%, preferred 150-250%, preferably about 200%.

Als Schutzfilm kommt auch eine PE- oder PP-Schutzschicht in Frage (Polyethylen oder Polypropylen), welche durch Adhäsion nicht klebend auf der Trägermaterialschicht haftet. Der Schutzfilm kann mit der Trägermaterialschicht koextrudiert sein. Die Aufdruckschichten können aus Lösungsmittellacken bestehen. Sie sind bevorzugt wasserunlöslich, hitzebeständig, farbecht, tonwertbeständig, opak und wärmestabil.A PE or PP protective layer also comes in as a protective film Question (polyethylene or polypropylene), which by adhesion does not adhere to the substrate layer. The Protective film can be co-extruded with the backing material layer his. The print layers can be made from solvent-based lacquers consist. They are preferably water-insoluble, heat-resistant, colourfast, tonal stable, opaque and heat stable.

Je nach verwendeten Materialien von Aufdruckschicht und Schutzfilm kann es vorkommen, daß die Aufdruckschichten nur schlecht direkt auf dem Schutzfilm haften, etwa wenn lösungsmittelhaltige Schichten auf einen kationisch UV-ausgehärteten Schutzfilm gedruckt werden sollen. In diesen Fällen empfiehlt es sich, vor dem Aufdrucken der Aufdruckschichten eine geeignete Primerschicht auf den Schutzfilm aufzudrucken. Die Primerschicht wirkt als Haftvermittler. Die Primerschicht kann einschichtig sein und außer haftvermittelnden Eigenschaften auch als Barriere gegen Einwanderung von Lösungsmitteln aus der Aufdruckschicht in den Schutzfilm wirken. Die Primerschicht kann eine schutzfilmseitige Haftschicht und darauf eine zusätzliche Barriereschicht aufweisen, oder vom Schutzfilm ausgehend eine Haftschicht, eine Barriereschicht und eine weitere Haftschicht, auf die dann die Aufdruckschichten gedruckt werden.Depending on the materials used, the print layer and Protective film it can happen that the print layers only adhere poorly directly to the protective film, for example if it contains solvents Layers on a cationically UV-cured Protective film should be printed. Recommended in these cases a suitable one before printing on the printing layers Print the primer layer on the protective film. The primer layer acts as an adhesion promoter. The primer layer can be single-layer and have non-adhesive properties also as a barrier against immigration from solvents the print layer act in the protective film. The primer layer can have a protective film-side adhesive layer and on top have an additional barrier layer, or from the protective film starting an adhesive layer, a barrier layer and another adhesive layer, on which the printed layers are then placed to be printed.

Die Dehnbarkeit der Aufdruckschicht und ggf. der Primerschicht, der Barriereschicht sowie der Haftschicht(en) kann an jene des Schutzfilms angepaßt sein, wobei die Dehnbarkeit der einzelnen Schichten von der Klebstoffseite zu der Schutzfilmseite abnehmen kann. Dies gestattet eine beschädigungsfreie Übertragung des Etiketts auf den Gegenstand bei gleichzeitig hoher Schutzwirkung des Schutzfilms.The elasticity of the print layer and possibly the primer layer, the barrier layer and the adhesive layer (s) can be adapted to that of the protective film, the extensibility of the individual layers from the adhesive side to the protective film side can decrease. This allows damage-free Transfer the label to the item at the same time high protective effect of the protective film.

Die Klebstoffschicht kann aus einem Haftklebstoff, einem erst nach einmaliger Wärmeeinwirkung dauerhaft klebenden thermoaktivierbaren Klebstoff oder einem nur während Erwärmung klebrigen thermosensitiven Klebstoff gebildet sein.The adhesive layer can consist of a pressure sensitive adhesive, a first After a single heat exposure, permanently adhesive thermo-activatable Glue or just sticky during heating thermosensitive adhesive can be formed.

Ein thermoaktivierbarer Klebstoff kann ein Zweikomponentenklebstoff sein, dessen eine Komponente oder eines Reaktionsmittels sich in Mikrokapseln befindet, die durch Wärmeeinwirkung platzen und dann eine Vermischung der beiden Komponenten und hierdurch eine Aushärtungsreaktion stattfindet. Die Verwendung derartiger Zweikomponentenklebstoffe beim Aufkleben von Etiketten auf Gegenstände ist unabhängig von der Konstruktion des Etiketts.A thermo-activatable adhesive can be a two-component adhesive be a component or a reactant is in microcapsules that are exposed to heat burst and then a mixture of the two components and this causes a curing reaction. The usage such two-component adhesives when gluing of labels on objects is independent of the construction of the label.

Beim Aufkleben des Etiketts auf den Gegenstand soll bei Verwendung eines thermoaktivierbaren Klebstoffs der Gegenstand möglichst genau auf diejenige Temperatur vorgewärmt sein, bei der die Klebstoffschicht beim Auftragen zu erwärmen ist. Die Temperatur soll in einem Bereich liegen, bei der eine reibungsmindernde Kunststoffbeschichtung einer zu etikettierenden Glasflasche nicht beschädigt wird.When sticking the label on the object should use a thermally activated adhesive is the object be preheated as precisely as possible to that temperature at which is to be warmed up during application. The Temperature should be in a range where a friction-reducing Plastic coating of a label Glass bottle is not damaged.

Hergestellt wird das Etikett durch Aufdrucken der jeweiligen Schichten nacheinander auf die Trägermaterialschicht, wobei der Schutzfilm und die Aufdruck- bzw. Farbschichten und ggf. der Primer im wesentlichen konturgleich auf die Trägermaterialschicht aufgedruckt werden. Der Schutzfilm kann zum Schutz der Ränder der Farbschichten diese überlappen. Die Klebstoffschicht wird ebenfalls konturgleich zu den Farbschichten und dem Schutzfilm aufgedruckt.The label is produced by printing on the respective one Layers in succession on the carrier material layer, wherein the protective film and the print or color layers and if necessary the primer is essentially the same shape on the substrate layer be printed on. The protective film can protect the edges of the color layers overlap them. The adhesive layer also has the same contour as the layers of paint and printed on the protective film.

Ein bevorzugtes Herstellungsverfahren beinhaltet folgende Schritte:

  • 1) Bereitstellen einer Trägermaterialschicht,
  • 2) konturiertes Aufdrucken einer aus zu vernetzendem Material bestehenden Schutzschicht direkt auf die Trägermaterialschicht,
  • 3) Durchpolymerisieren der Schutzschicht zu einem im wesentlichen nicht plastifizierbaren Schutzfilm, der durch Adhäsion im wesentlichen unabhängig von der Temperatur des Etiketts von der Trägermaterialschicht lösbar auf der Trägermaterialschicht haftet,
  • 4) konturiertes Aufdrucken wenigstens einer Aufdruckschicht auf den Schutzfilm, und
  • 5) konturiertes Aufdrucken von Klebstoff auf die Aufdruckschicht.
    • A preferred manufacturing process includes the following steps:
  • 1) providing a carrier material layer,
  • 2) contoured printing of a protective layer consisting of material to be crosslinked directly onto the carrier material layer,
  • 3) polymerisation of the protective layer through to an essentially non-plasticizable protective film which adheres to the carrier material layer in a detachable manner regardless of the temperature of the label,
  • 4) contoured printing of at least one printing layer on the protective film, and
  • 5) Contoured printing of adhesive on the printing layer.

    • Nach der Übertragung des Etiketts auf den Gegenstand wirkt dieser wie bedruckt und nicht wie mit einem flächigen Etikett versehen.After transferring the label to the object this as printed and not as with a flat label Mistake.

    Bevorzugte Ausführungen werden nun unter Hinweis auf die beigefügten Zeichnungen beschrieben.

  • Fig. 1 zeigt im Schnitt schematisch eine erste Ausführung eines Transferetiketts; und
  • Fig. 2 zeigt im Schnitt schematisch eine zweite Ausführung eines Transferetiketts.
    • Preferred embodiments will now be described with reference to the accompanying drawings.
  • Fig. 1 shows schematically in section a first embodiment of a transfer label; and
  • Fig. 2 shows schematically in section a second embodiment of a transfer label.

    • Zu Fig. 1. Ein Trägermaterial 1, das mehrschichtig aus koextrudiertem Polypropylen oder Polyethylen auf einem Papierträger gebildet sein kann und eine Dicke von 20 bis 100 µm aufweisen kann, weist eine wenig haftende Oberfläche 1a des Polypropylens mit geringer Oberflächenenergie auf. Bei der Koextrusion werden mehrere thermoplastische Kunststoffe gemeinsam extrudiert. Es entstehen mehrschichtige Folien, die gegenüber einfachen Folien den Vorteil haben, daß die einzelnen Schichten unterschiedliche Funktionen haben können (z.B. glatte Außenschicht für gute Bedruckung oder Innenschichten mit adhäsiver Oberfläche für geringe Blockwirkung).To Fig. 1. A carrier material 1, the multi-layer of coextruded Polypropylene or polyethylene on a paper backing can be formed and have a thickness of 20 to 100 microns has a low-adhesion surface 1a of the polypropylene with low surface energy. With coextrusion several thermoplastic materials are common extruded. The result is multilayer films that face each other simple foils have the advantage that the individual Layers can have different functions (e.g. smooth outer layer for good printing or inner layers with adhesive surface for low blocking effect).

    Das Polypropylen oder Polyethylen ist unvorbehandelt, so daß es eine geringe Oberflächenenergie bzw. Oberflächenspannung von z.B. 28-32 mN/m hat. Auf diese wenig haftende Oberfläche 1a wird konturiert eine bevorzugt präpolymerisierte Schutzschicht aufgedruckt. Anschließend wird die Schutzschicht zu einem Schutzfilm durchpolymerisiert, der nicht mehr durch Auflösung seiner Kohäsion plastifizierbar ist. Die unmittelbar aufeinanderliegenden Oberflächen 1a des Trägermaterials 1 und 3a des Schutzfilms haften durch physikalische Adhäsion aufeinander, etwa elektrostatische Kräfte. Durch die Adhäsion haftet der Schutzfilm 3 nur wenig auf dem Trägermaterial 1, klebt nicht verhältnismäßig fest wie etwa bei Haftklebern. The polypropylene or polyethylene is untreated so that it has a low surface energy or surface tension from e.g. 28-32 mN / m. On this little sticky surface 1a is contoured a preferably prepolymerized protective layer printed on. Then the protective layer is closed polymerized through a protective film that no longer through Dissolution of its cohesion is plastifiable. The immediately superimposed surfaces 1 a of the carrier material 1 and 3a of the protective film adhere through physical adhesion on each other, such as electrostatic forces. By adhesion the protective film 3 adheres only slightly to the carrier material 1, does not stick relatively firmly, such as with pressure sensitive adhesives.

    Die Haftwirkung ist temperaturunabhängig. Der Schutzfilm 3 besteht bevorzugt aus kationisch kalt-vernetzendem, unter UV-Bestrahlung aushärtendem Lack, der durch UV-Anstoß eine Kettenreaktion beginnt und vollständig aushärtet und nach Aushärtung nicht-klebend bleibt.The adhesive effect is independent of temperature. The protective film 3 consists preferably of cationically cold-crosslinking, under UV radiation curing varnish, which is a chain reaction due to UV light starts and cures completely and after curing remains non-sticky.

    Die Dicke des Schutzfilms beträgt 1 bis 10 µm, bevorzugt 2,5 - 2 µm. Bevorzugt ist der Schutzfilm zur Aufnahme von Zug- und Quetschkräften sowie Distorsionen beim Übertragungsprozeß auf den Gegenstand elastisch, etwa mit einer Dehnbarkeit im Bereich von etwa 50 - 400 %, etwa 100 - 300 %, insbesondere etwa 150 - 250 %, bevorzugt ca. 200 % nach DIN 53455 (Reißdehnung des Schutzfilmmaterials). Bevorzugt enthält der UV-härtende Schutzfilm in seiner Grundzusammensetzung Acrylsäurepolymere, etwa ca. 40 Gew.-% Polyurethan-Acrylat-Polymermischung, ca. 20 Gew.-% monofunktionales Octyl-Decyl-Acrylat und ca. 35 Gew.-% Tri-Propylen-Glycol-Di-Acrylat (TPGDA), und als Rest Zusatzstoffe.The thickness of the protective film is 1 to 10 μm, preferably 2.5 - 2 µm. The protective film for absorbing tensile and crushing forces as well as distortions during the transmission process elastic on the object, for example with an elasticity in the Range of about 50-400%, about 100-300%, in particular about 150 - 250%, preferably about 200% according to DIN 53455 (elongation at break of the protective film material). The UV-curing agent preferably contains Protective film in its basic composition acrylic acid polymers, about 40% by weight polyurethane-acrylate polymer mixture, approx. 20% by weight of monofunctional octyl decyl acrylate and about 35 wt% tri-propylene glycol di-acrylate (TPGDA), and the rest additives.

    Alternativ kann es sich um einen UV-härtenden radikalischen Lack handeln, dessen Aushärtung so lange stattfindet, solange UV-Bestrahlung einwirkt. Auch dieser Lack kann die oben genannten Dehnbarkeitswerte haben. In Frage kommen auch unter Elektronenbestrahlung aushärtende Lacke sowie Polyethylen oder Polypropylenschichten, die in der genannten Wechselwirkung auf dem Trägermaterial haften. Hierzu kommen als Materialpaarungen von Trägermaterial und Schutzfilm in Betracht:

    EVA/PE =
    Ethylenvinylacetat/Polyethylen
    EVA/PP =
    Ethylenvinylacetat/Polypropylen
    WPVC/PE =
    Weich-Polyvinylchlorid/Polyethylen
    WPVC/PP =
    Weich-Polyvinylchlorid/Polypropylen.
    Alternatively, it can be a UV-curing radical varnish, the curing of which takes place as long as UV radiation acts. This varnish can also have the stretch values mentioned above. Lacquers which cure under electron irradiation and polyethylene or polypropylene layers which adhere to the carrier material in the aforementioned interaction are also suitable. For this purpose, material pairings of carrier material and protective film can be considered:
    EVA / PE =
    Ethylene vinyl acetate / polyethylene
    EVA / PP =
    Ethylene vinyl acetate / polypropylene
    WPVC / PE =
    Soft polyvinyl chloride / polyethylene
    WPVC / PP =
    Soft polyvinyl chloride / polypropylene.

    Auf den Schutzfilm 3 ist, dessen Konturen im wesentlichen folgend, eine Farbschicht 5 aus bevorzugt lösungsmittelhaltigem Lack aufgedruckt. Dieser Lack ist - wie der Schutzfilm auch - wärmestabil. Ferner ist die Farbschicht wasserunlöslich, hitzebeständig, farbecht, tonwertbeständig und opak.On the protective film 3, its contours are essentially following, a color layer 5 of preferably solvent-based Lacquer printed. This paint is - like the protective film also - heat stable. Furthermore, the color layer is insoluble in water, heat-resistant, colourfast, tonal value and opaque.

    Auf die Farbschicht 5 ist eine - je nach Anwendungsfall - kaltklebende oder durch Wärme aktivierbare Klebstoffschicht 7 konturgleich mit Farbschicht 5 und Schutzfilm 3 aufgedruckt. Die Dicke der Klebstoffschicht 7 beträgt 2 bis 40 µm. Bevorzugt ist die Dehnbarkeit der Farbschicht 5 an jener des Schutzfilms angepaßt und ist insbesondere größer als die des Schutzfilms.Depending on the application, one is on the color layer 5 Cold-adhesive or heat-activated adhesive layer 7 printed with the same contour with ink layer 5 and protective film 3. The thickness of the adhesive layer 7 is 2 to 40 microns. Prefers is the elasticity of the color layer 5 on that of Adapted protective film and is in particular larger than that of Protective film.

    Zur Übertragung des Etiketts vom Trägermaterial 1 auf die Oberfläche eines Gegenstands G wird bevorzugt der Gegenstand auf die Klebetemperatur der Klebstoffschicht 7 vorgewärmt. Dann wird das Trägermaterial mit dem darauf adhäsiv haftenden Etikett auf den Gegenstand mittels einer Wärmeplatte oder Wärmewalze aufgedrückt, so daß die Klebstoffschicht 7 klebrig wird und mit ihr die konturgleiche Farbschicht 5 und Schutzfilmschicht 3 auf dem Gegenstand kleben bleiben. Dann wird das Trägermaterial in der in Fig. 1 mit T bezeichneten Trennebene von dem Schutzfilm 3 abgezogen und entfernt. Das Abziehen des Trägermaterials kann - etwa bei Verwendung einer Übertragungswalze, auch kurz vor dem Aufkleben des Etiketts auf den Gegenstand erfolgen, oder, falls etwa das Etikett auf den Gegenstand aufmassiert werden muß, auch nach dem Aufkleben. Die Dehnbarkeit des Trägerbandmaterials ist deutlich geringer als die der Etikettenschichten 3, 5 und 7, bevorzugt 50 - 150 %.To transfer the label from the carrier material 1 to the The surface of an object G is preferably the object preheated to the adhesive temperature of the adhesive layer 7. Then the carrier material with the adhesive adhering to it Label on the item using a hot plate or Heat roller pressed on, so that the adhesive layer 7 sticky and with it the contour-like color layer 5 and protective film layer 3 stick to the object. Then it will be the carrier material in the parting plane designated T in FIG. 1 peeled and removed from the protective film 3. The stripping of the carrier material - for example when using a transfer roller, also just before sticking the label on the object, or if, for example, the label on the Object must be massaged, even after sticking. The elasticity of the carrier tape material is significantly less than that of the label layers 3, 5 and 7, preferably 50 - 150%.

    Die vor der Übertragung die Trägerschicht 1 berührende Oberfläche 3a des Schutzfilms 3 bildet nun die Außenfläche des fertigen Etiketts, wobei die UV-gehärtete Schutzfilmschicht 3 das Etikett gegen Verkratzen schützt. Infolge der Adhäsionsverbindung ist nach dem Trennen des Trägermaterials 1 weder dieses noch der Schutzfilm 3 klebrig.The surface touching the carrier layer 1 before the transfer 3a of the protective film 3 now forms the outer surface of the finished labels, the UV-hardened protective film layer 3 protects the label against scratching. As a result of the adhesive bond after the separation of the carrier material 1 is neither this still the protective film 3 sticky.

    Die Konturen des Schutzfilms können diejenigen der Farb- und Klebstoffschicht ein wenig überlappen, so daß bei übertragenem Etikett der Schutzfilm auch die Konturkanten von Farb- und Klebstoffschicht abdeckt und schützt.The contours of the protective film can match those of the color and Overlap the adhesive layer a little so that when transferred Label the protective film also the contour edges of color and covers and protects adhesive layer.

    Fig. 2 zeigt eine weitere Ausführung eines Transferetiketts. Zur obigen Ausführung entsprechende Schichten sind mit gleichen Bezugszahlen versehen, vermehrt um die Zahl 100. Auf das Trägermaterial 101 ist ein Schutzfilm 103 aus kationisch kalt-härtendem UV-Lack aufgedruckt, wobei ihre aneinanderliegenden Oberflächen 101a bzw. 103a durch Adhäsion temperaturunabhängig aneinanderhaften.2 shows a further embodiment of a transfer label. Layers corresponding to the above embodiment are the same Provide reference numbers, increased by the number 100. On the Carrier material 101 is a protective film 103 made of cationic cold-curing UV varnish printed, with their adjacent Surfaces 101a and 103a are independent of temperature due to adhesion stick together.

    Auf den Schutzfilm 103 ist eine Primerschicht 109 aufgedruckt, die gleichzeitig eine Barriere bilden kann gegen von darauf aufzudruckenden Farbschichten austretende Lösungsmittel. Je nach der Materialpaarung von Schutzfilm und Farbschichten kann die Primerschicht mehrere Teilschichten aufweisen, zum Beispiel eine Haftvermittlungsschicht 109a auf dem Schutzfilm 103, eine Barriereschicht 109b gegen wandernde Lösungsmittel und darauf wiederum eine Haftvermittlungsschicht 109c für die darauf aufgedruckten Farbschichten 105. In der dargestellten Ausführung sind fünf Farbschichten 105a bis 105e dargestellt. Selbstverständlich ist auch jede andere Anzahl von Farbschichten denkbar. Bei den Farbschichten handelt es sich wie oben um lösungsmittelhaltige Lacke, die wärmestabil sind, wasserunlöslich, farbecht, tonwertbeständig und opak.A primer layer 109 is printed on the protective film 103, which can simultaneously form a barrier against it leaking solvents to be printed on color layers. Depending on the material pairing of protective film and layers of paint the primer layer can have several sublayers, for Example an adhesion promoting layer 109a on the protective film 103, a barrier layer 109b against migrating solvents and then an adhesive layer 109c for the color layers 105 printed thereon. In the illustrated Five layers of color 105a to 105e are shown. Of course, any other number of layers of paint conceivable. The color layers are like above around solvent-based paints that are heat-stable, insoluble in water, colourfast, tonal value stable and opaque.

    Die Dehnbarkeit der Primerschicht(en) 109a-c und hier der Farbschicht(en) 105a-e können jeweils an jene des Schutzfilms 103 angepaßt sein. Insbesondere liegt die Dehnbarkeit der Primerschicht(en) zwischen der des Schutzfilms 103 und der der Farbschicht(en) 105a-e.The extensibility of the primer layer (s) 109a-c and here the Color layer (s) 105a-e can each be attached to that of the protective film 103 be adapted. In particular, the stretchability of the Primer layer (s) between that of the protective film 103 and the the color layer (s) 105a-e.

    Auf die letzte Farbschicht 105e wird dann konturgleich mit Schutzfilm 103, Primerschicht 109 und der wenigstens einen Farbschicht 105 eine thermoaktivierbare Klebstoffschicht 107 aufgedruckt, die wie in der ersten Ausführung ausgebildet sein kann. The last color layer 105e then has the same shape Protective film 103, primer layer 109 and the at least one Color layer 105 is a thermally activated adhesive layer 107 printed on, which are designed as in the first embodiment can be.

    Das Trägermaterial 101 weist auf seiner von dem Schutzfilm 103 abweisenden Seite eine haftabweisende Schicht 101b aus Silikon oder Trennlack auf, welche verhindert, daß bei aufgewickeltem Trägerbandmaterial 101 mit einer Vielzahl darauf haftender Etiketten die Klebstoffschicht 107 der nächsten Lage von Etiketten im Wickel auf dem Trägerbandmaterial 101 festklebt. Die Dehnbarkeit des Trägerbandmaterials 101 ist deutlich geringer als die der Etikettenschichten 103, 105, 109 und beträgt etwa 50 - 150 %.The carrier material 101 faces the protective film 103 repellent side an adhesive layer 101b Silicone or release varnish, which prevents that when wound Carrier tape material 101 having a plurality thereon adhesive labels, the adhesive layer 107 of the next Position of labels in the roll on the carrier tape material 101 sticks. The extensibility of the carrier tape material 101 is significantly less than that of the label layers 103, 105, 109 and is about 50-150%.

    Die Übertragung des Etiketts vom Trägermaterial 101 auf den Gegenstand G geschieht in gleicher Weise wie oben beschrieben, wobei sich nach der Übertragung das Trägerbandmaterial 101 rückstandsfrei entlang der Trennebene T zwischen den beiden Oberflächen 101a des Trägermaterials 101 und der Oberfläche 103a des Schutzfilms trennt.The transfer of the label from the carrier material 101 to the Item G happens in the same way as described above, the carrier tape material after the transfer 101 residue-free along the parting plane T between the two Surfaces 101a of the carrier material 101 and the surface 103a of the protective film separates.
