Abstract

Production of an image-transfer film involving coating a carrier (11) with a clear lacquer (12), applying an image-forming toner substrate (13) and then covering with a layer of liquid adhesive (14) further involves removing layer (14) from the clear lacquer layer (12), thus allowing liquid adhesive into toner substrate (13). An Independent claim is also included for an imaging film comprising a clear lacquer layer (12) with an adhesive-containing toner substrate (13).

Description

Die Erfindung betrifft ein Verfahren zur Herstellung einer Bildübertragungsfolie zur Übertragung eines Bildes von der Bildübertragungsfolie auf einen Bildträger nach dem Oberbegriff des Patentanspruches 1 und eine nach dem Verfahren hergestellte Bildübertragungsfolie nach dem Oberbegriff des Patentanspruches 4.The invention relates to a method for producing an image transfer film for transferring an image from the image transfer film on an image carrier according to the preamble of Claim 1 and a manufactured by the method Image transfer film according to the preamble of the claim 4th

Der sogenannte Trockentransfer kennzeichnet sich dadurch, dass ein Bild von einer Bildübertragungsfolie (folgend kurz Bildfolie) auf einen Bildträger (folgend kurz Träger) übertragen wird. Dabei werden nicht die die bildliche, graphische oder sonstige Darstellung bildenden Pigmentfarbstoffe als Haufwerke (folgend kurz Tonersubstrat oder Substrat) als solche übertragen, sondern das Substrat wird mit der Bildfolie übertragen, die anschliessend in auf dem Träger verbleibende Bildabschnitte und vom Träger abgezogene Bildfolienreste vereinzelt wird. Dazu ist eine Bildfolie bekannt, die in Form eines Laminates eine Tragschicht, eine auf die Tragschicht aufgebrachte Schicht aus einem Klarlack, auf der Klarlackschicht Bildern entsprechende Tonersubstrat und eine Tonersubstrat und Klarlackschicht abdeckende Schicht aus einem Klebstoff umfasst. Dieses Laminat wird mit dem Träger über die Klebschicht, beispielsweise durch Druck und Wärme in Eingriff gebracht. Bei diesem Vorgang bildet sich eine um den Umfang der Fläche des Substrates umlaufende, senkrecht zur Klebschicht stehende Bruchstelle, die sich in die Klarlackschicht fortsetzt. Die Bruchstelle bildet sich, weil das Tonersubstrat mit abdeckender Klebschicht von dem Laminat aus Tragschicht, Klarlackschicht und Klarlackschicht überziehender Klebschicht abragt. Die Adhäsion (Haftungskräfte) sind so eingestellt, dass die Adhäsion zwischen der Klebschicht und dem Substrat und Klarlackschicht grösser ist als die Adhäsion zwischen Klarlackschicht und Tragschicht. Nachdem die Bildfolie mit dem Träger in Eingriff gebracht ist, folgt als nächster Fertigungsschritt die Vereinzelung der auf dem Substrat aufgebrachten Bildfolie in Bildabschnitte und Bildfolienreste, indem die Bildfolie wieder vom Träger abgezogen wird. Dabei löst sich die Bildfolie entlang den Bruchstellen abreissend und aufgrund der Adhäsionsdifferenz die Tragschicht sich von der Klarlackschicht über dem Substrat trennend ab, so dass auf dem Träger von letzterem her gesehen, die Klebschicht, das Substrat und die das Substrat überdeckende Klarlackschicht verbleibt, der Rest der Trägerfläche frei, d.h. unbedeckt von Bildfolie ist. Dieser Trennungsvorgang, d.h. das Herauslösen der Bildabschnitte aus der Bildfolie wird von der Fachwelt als "selective release" oder auch "weeding" als Synonym dazu bezeichnet. Beide Bezeichnungen charakterisieren die Entfernung der Bildfolienreste entlang bestimmter Bruchstellen (in Klebschicht, Substrat und Klarlackschicht), wobei die Delamition von Bildfolienschichten (Tragschicht von der Klarlackschicht) nicht unter den Begriff des "weeding" fällt. Die bekannte Bildfolie hat den Nachteil, dass es beim "selective release" fallweise vorkommt, dass der Bildfolienrest sich nicht einwandfrei entlang der umlaufenden Bruchlinie der auf dem Träger verbleibenden Klebschicht des Bildabschnittes löst, was sich in Form von Fehldrucken darstellt, die mit Blick auf wirtschaftliche Fertigungsgeschwindigkeiten ohne Einzelobjektinspektionen nicht hinnehmbar sind. Ausgehend von diesem Stand der Technik hat sich der Erfinder die Aufgabe gestellt, ein Verfahren zur Herstellung einer Bildfolie und eine nach dem Verfahren ausgestaltete Bildfolie zu entwickeln, mit der eine fehlerbehaftete Abtrennung, d.h. Vereinzelung der Bildfolie in Bildabschnitte und Bildfolienreste vermieden ist und diese Aufgabe wird durch ein Herstellverfahren mit den kennzeichnenden Merkmalen des Patentanspruches 1 und durch eine Bildfolie mit den kennzeichnenden Merkmalen des Patentanspruches 4 gelöst. Vorteilhafte Ausgestaltungen kennzeichnen die den Ansprüchen 1 und 4 folgenden Ansprüche.The so-called dry transfer is characterized in that an image from an image transfer film (hereinafter referred to as image film) an image carrier (hereinafter referred to as carrier) is transmitted. there will not be the visual, graphical or other representation forming pigment dyes as piles (hereinafter briefly toner substrate or substrate) as such, but the Substrate is transferred with the image film, which is then in on image sections remaining on the carrier and subtracted from the carrier Scraps of film is isolated. A picture slide is known for this, the one in the form of a laminate, one on the base applied layer of a clear lacquer, on the clear lacquer layer A toner substrate corresponding to images and a toner substrate and clear coat layer covering layer of an adhesive includes. This laminate is covered with the backing over the adhesive layer, brought into engagement by pressure and heat, for example. at this process forms around the circumference of the surface of the Substrate circumferential, perpendicular to the adhesive layer Breakage that continues in the clear coat. The breaking point forms because the toner substrate has a covering adhesive layer of the laminate of base layer, clear lacquer layer and Protruding clear coat layer adhesive layer. Adhesion (Liability forces) are set so that the adhesion between the adhesive layer and the substrate and clear lacquer layer is larger than the adhesion between the clear lacquer layer and base layer. After this the image film is engaged with the carrier follows as The next step in the manufacturing process is the separation of those on the substrate applied picture film in picture sections and picture film residues, by pulling the picture film off the support. This solves the image film tearing off along the break points and due to the difference in adhesion between the base layer and the clear coat separating over the substrate, so that on the Carrier seen from the latter, the adhesive layer, the substrate and the clear lacquer layer covering the substrate remains, the Rest of the support surface free, i.e. is not covered by film. This Separation process, i.e. the removal of the image sections The image slide is called "selective release" by the experts or also "Weeding" referred to as a synonym. Both names characterize the removal of the film residues along certain Fractures (in adhesive layer, substrate and clear lacquer layer), the delamition of image film layers (base layer of the clear coat) does not fall under the term "weeding". The well-known picture film has the disadvantage that "selective release" Occasionally it happens that the image film remnant is not working properly along the circumferential fault line that on the carrier remaining adhesive layer of the image section dissolves what is in Form of misprints represents that with a view to economic Production speeds without individual object inspections are not are acceptable. Based on this state of the art the inventor set himself the task of a method for Production of an image film and one designed according to the method To develop image film with which a faulty separation, i.e. Separation of the image film into image sections and Image film residue is avoided and this task is done by a Manufacturing process with the characteristic features of Claim 1 and through a picture film with the characterizing features of claim 4 solved. Advantageous configurations characterize claims 1 and 4 following claims.

Die Erfindung weicht zur Lösung der Aufgabe der Erfindung von der herrschenden Praxis dadurch ab, dass sie bei Verklebung einer Bildfolie mit einem Träger, Klebstoff nur entsprechend den geometrischen Konfigurationen der Bildteile der Bildfolie, d.h. entsprechend denen der Tonersubstrate bereitstellt, indem die Substrate in ihnen aufgenommene Klebstoffmengen zum Zeitpunkt der Verklebung oder Beschichtung freisetzen. Mit dieser "sektoriellen" Freisetzung erübrigen sich die aus dem Stand der Technik bekannten Bruchlinien, so dass der selective release mit der ihm anhaftenden Problematik unter Erhöhung der Fertigungssicherheit umgangen ist.The invention deviates from to achieve the object of the invention prevailing practice in that when a Image film with a carrier, adhesive only according to the geometric configurations of the image parts of the image film, i.e. corresponding which the toner substrates provide by the substrates Amounts of adhesive in them at the time of Release adhesive or coating. With this "sectoral" There is no need for releases known from the prior art Fault lines, so that the selective release with the adherent Problems with increased manufacturing security is circumvented.

Gemäss Fig. 1 umfasst die erfindungsgemässe Bildfolie 10 eine Tragschicht 11, eine Klarlackschicht 12 und Druckbilder darstellende Tonersubstrate 13 (nur ein Tonersubstrat ist dargestellt). Die Beschichtung der Tragschicht 11 mit der Klarlackschicht 12 erfolgt nach herkömmlichen Techniken. Die Tragschicht 11 ist bevorzugt eine Folie, vorzugsweise aus einem Polyester oder aus einem glattbeschichteten Papier, mit einer Stärke von 20 bis 50 µm, vorzugsweise einer Stärke von 23 bis 26 µm. Die auf die Tragschicht 11 aufgebrachte Klarlackschicht 12 ist aus einem Acryllack gebildet. Dieser Acryllack ist mit einem Trennmittel versetzt, das die Trennung der Tragschicht 11 von der Klarlackschicht 12 nach erfolgtem Druckvorgang begünstigt. Das Trennmittel ist vorzugsweise ein verdampfbares Wachs, das dem Acryllack der Klarlackschicht 12 in Anteilen (Gewicht) von 2% bis 5%, vorzugsweise 2,5% bis 3,5%, beigegeben ist. Der Druckvorgang erfolgt unter Anwendung von Wärme und Druck, wobei die in Bildfolie 10 eingetragene Wärme das Wachs verdampfen lässt. Auf die Klarlackschicht 11 werden die Druckbilder, d.h. die Druckbilder darstellenden Tonersubstrate 13 aufgebracht. Die Aufbringung des Substrates 13 wird bevorzugt von Computer gesteuerten Druckern vorgenommen, die nach Massgabe eines in einer EDV (Computer) Einrichtung gespeicherten Vorschrift oder Programm Tonerpartikel nach Farbe, Menge und den Bereich des Druckbildes zur Ablagerung bringen. Das Substrat 13 wird so aufgebracht, dass die zur Ansicht bestimmte Bildfläche des Substrates 13 mit der Klarlackschicht in Eingriff steht. Nach Aufbringung des oder der Substrate 13 wird ein oder mehrere Substrate 13 tragenden Fläche 12a vollflächig, mit einer auch Substrate 13 überdeckende Klebschicht 14 überzogen, die anschliessend wieder vollflächig, ausgenommen in Substrate 13 eingetragenen Klebstoff, entfernt wird. Auftrag und Entfernung der Klebschicht 14 erfolgen durch rakelähnliche Beschichtungsleisten, die in gleichgerichteter Arbeitsrichtung der Be- und Entschichtungseinrichtung einander folgend flüssigen Klebstoff aus einem Vorratsbehälter abziehen, um ihn nach der Beschichtung als solchen einem Aufnahmebehälter wieder zuzuführen. Das Tonersubstrat 13 kennzeichnet sich durch eine grössere Rauhigkeit und Porosität als die Klarlackschicht 11, was zur Folge hat, dass bei Entfernung der vollflächig aufgebrachten Klebschicht 14 Klebstoff dieser Schicht in das Tonersubstrat 13 als ein dort verbleibender und verfügbarer Klebmittelvorrat eingetragen wird. Der Klebstoff wird bei erhöhter Temperatur, d.h. bei einer Temperatur von 100% C bis 140% C, vorzugsweise 120% - 130% C, in schmelzflüssigen Zustand aufund anschliessend abgetragen, wobei der im Substrat aufgenommene Klebstoff anschliessend abkühlt und sich verfestigen kann, um sich bei Aufbringung der Bildfolie 10 auf einen Träger 15 zufolge der dabei eingetragenen Wärme wieder zu Klebzwecken zu verflüssigen und anschliessend zu erstarren. Fig. 2 zeigt in schematisierter Form eine Vorrichtung 16 zur Aufbringung einer Bildfolie 10 auf einen Träger 15 (z.B. eine Compact Disc). Sie zeigt den Träger 15 und einen Stempel 17, vorzugsweise aus Silikon, zwischen denen die Bildfolie 10 nach der Erfindung angeordnet ist. Vor oder während der Aufbringung wird die Bildfolie 10 erhitzt und durch Niederfahren des Stempels 17 mit dem Träger 15 verbunden, indem der durch die Erwärmung reaktivierte Klebstoff aus dem Substrat 13 herausgepresst wird. Der für die Verbindung notwendige Druck kann auch durch eine Walze (nicht gezeigt) auf die Bildfolie 10 aufgebracht werden. Die Drücke, die Stempel 17 oder eine Walze aufzubringen haben, liegen zwischen 0,75 kg pro mm2 und 1,5 kg pro mm2, vorzugsweise zwischen 1,0 kg pro mm2 und 1,2 kg pro mm2. Nach der Verklebung wird die Tragschicht 11 von der Klarlackschicht 12 abgezogen, so dass auf dem Träger 15 der Klebstoff, das Substrat 13 mit der das Substrat 13 überspannenden Klarlackschicht 12 als Schutzschicht für das Substrat 13 verbleibt.1, the image film 10 according to the invention comprises a support layer 11, a clear lacquer layer 12 and toner substrates 13 representing printed images (only one toner substrate is shown). The base layer 11 is coated with the clear lacquer layer 12 using conventional techniques. The support layer 11 is preferably a film, preferably made of a polyester or a smooth-coated paper, with a thickness of 20 to 50 microns, preferably a thickness of 23 to 26 microns. The clear lacquer layer 12 applied to the base layer 11 is formed from an acrylic lacquer. This acrylic lacquer is mixed with a release agent which favors the separation of the base layer 11 from the clear lacquer layer 12 after the printing process has taken place. The release agent is preferably a vaporizable wax which is added to the acrylic lacquer of the clear lacquer layer 12 in proportions (weight) of 2% to 5%, preferably 2.5% to 3.5%. The printing process is carried out using heat and pressure, the heat entered in image film 10 allowing the wax to evaporate. The printed images, ie the toner substrates 13 representing the printed images, are applied to the clear lacquer layer 11. The application of the substrate 13 is preferably carried out by computer-controlled printers which, according to a rule or program stored in an EDP (computer) device, deposit toner particles according to color, quantity and the area of the printed image. The substrate 13 is applied such that the image surface of the substrate 13 intended for viewing is in engagement with the clear lacquer layer. After the application of the substrate or substrates 13, one or more substrates 12 carrying surface 13 are coated over their entire surface with an adhesive layer 14, which also covers substrates 13, which is then removed again over the entire surface, except for the adhesive that is entered in substrates 13. The application and removal of the adhesive layer 14 are carried out by doctor-like coating strips which, in the same working direction of the coating and de-coating device, pull successively liquid adhesive out of a storage container in order to feed it again as such to a receiving container. The toner substrate 13 is characterized by greater roughness and porosity than the clear lacquer layer 11, which has the consequence that when the adhesive layer 14 applied over the entire surface is removed, adhesive of this layer is introduced into the toner substrate 13 as a supply of adhesive remaining and available there. The adhesive is melted and then removed at elevated temperature, ie at a temperature of 100% C to 140% C, preferably 120% - 130% C, whereby the adhesive absorbed in the substrate then cools and can solidify to itself when the image film 10 is applied to a carrier 15, as a result of the heat entered, to liquefy again for adhesive purposes and then to solidify. 2 shows in a schematic form a device 16 for applying an image film 10 to a carrier 15 (for example a compact disc). It shows the carrier 15 and a stamp 17, preferably made of silicone, between which the image film 10 according to the invention is arranged. Before or during the application, the image film 10 is heated and connected to the carrier 15 by lowering the stamp 17 by pressing the adhesive reactivated by the heating out of the substrate 13. The pressure required for the connection can also be applied to the image film 10 by a roller (not shown). The pressures which stamp 17 or a roller have to apply are between 0.75 kg per mm 2 and 1.5 kg per mm 2 , preferably between 1.0 kg per mm 2 and 1.2 kg per mm 2 . After the adhesive bonding, the base layer 11 is pulled off the clear lacquer layer 12, so that the adhesive, the substrate 13 with the clear lacquer layer 12 spanning the substrate 13 remains on the carrier 15 as a protective layer for the substrate 13.
