Abstract
Description
Die vorliegende Erfindung betrifft eine mit einem Laserstrahl beschriftbare Folie gemäß vorliegendem Anspruch 1.The present invention relates to a film which can be inscribed with a laser beam.
Unter einer Beschriftung sind im folgenden graphische Symbole und Zeichen jeglicher Art zu verstehen. Die Schutzschicht kann beispielsweise eine Kunststoffolie, eine Schutzlackschicht oder dergleichen sein.In the following, labeling is to be understood to mean graphic symbols and signs of any kind. The protective layer can be, for example, a plastic film, a protective lacquer layer or the like.
Eine Folie dieser Art ist aus der internationalen Veröffentlichung W098/16397 bekannt. Das durch den Laserstrahl veränderbare Medium der bekannten Folie weist unter einer durch den Laserstrahl ablatierbaren, metallischen Schicht eine kontrastbildende Schicht mit einer Färbung auf, die sich von der Farbe der metallischen Schicht unterscheidet. Unter "Ablatieren" ist dabei das Abtragen oder Zerstören einer Schicht zu verstehen, die so ihre Opazität verliert.A film of this type is known from international publication W098 / 16397. The medium of the known film which can be changed by the laser beam has, under a metallic layer which can be ablated by the laser beam, a contrast-forming layer with a coloring which differs from the color of the metallic layer. "Ablating" means the removal or destruction of a layer, which loses its opacity.
Werden nun Flächenanteile in Form von Buchstaben oder grafischen Symbolen durch Lasereinwirkung aus der metallischen Schicht ablatiert, so werden diese Zeichen in der Farbe der kontrastbildenden Schicht durch die Schutzschicht hindurch erkennbar, während die nicht ablatierten Bereiche in der Farbe der Metallisierung sichtbar bleiben. Die Lasereinwirkung erfolgt hierbei von der Seite der Schutzschicht her durch die Schutzfolie hindurch.If areas of the surface in the form of letters or graphic symbols are ablated from the metallic layer by laser action, these characters can be recognized in the color of the contrast-forming layer through the protective layer, while the areas which have not been ablated remain visible in the color of the metallization. The laser action takes place from the side of the protective layer through the protective film.
Allerdings bleibt man bei der Anwendung beschriftbarer Folien nach Art der in WO98/16397 offenbarten Folie, was das farbige Erscheinungsbild betrifft, beschränkt, sofern man den Herstellungsaufwand vertretbar halten möchte: Die ablatierten Bereiche erscheinen durch die Schutzschicht hindurch in der Farbe der Kontrastschicht, die nicht ablatierten Bereiche in der Farbe der Metallisierung. Bei den üblicherweise eingesetzten Metallisierungen handelt es sich im wesentlichen um schwarze oder silberweiße Metallisierungen. Somit ergeben sich als mögliche Farbgebungen weiße oder buntfarbigee Beschriftung mit schwarzem Hintergrund oder schwarze oder buntfarbige Beschriftung mit silberweißem Hintergrund. Zwar sind andersfarbige Metallisierungen prinzipiell denkbar, jedoch werden die zur Verfügung stehenden Farben, insbesondere wenn man den Preis mancher "bunter" Metalle bzw. deren Aufbringung als Dünnschicht in Betracht zieht, stets auf eine geringe Anzahl begrenzt bleiben. Einfaches farbiges Bedrucken der Schutzschicht scheidet meist aus, da laserbeschriftete Folien ja in erster Linie dort eingesetzt werden, wo man aus Gründen der Beständigkeit gegen Abrieb oder Ausbleichen auf bedruckte Folien verzichten muß.However, the use of writable films of the type disclosed in WO98 / 16397 in terms of color appearance remains limited, provided that the manufacturing effort is to be justified: the ablated areas appear through the protective layer in the color of the contrast layer, which is not ablated areas in the color of the metallization. The metallizations usually used are essentially black or silver-white metallizations. The possible colors are white or multicolored lettering with a black background or black or multicolored lettering with a silver-white background. Different colored metallizations are in principle conceivable, but the available colors, especially if one takes into account the price of some "colorful" metals or their application as a thin layer, will always be limited to a small number. Simple colored printing of the protective layer is usually ruled out, since laser-labeled foils are primarily used where there is no need to use printed foils for reasons of resistance to abrasion or fading.
Der Erfindung liegt demnach die Aufgabe zugrunde, eine mit einem Laserstrahl beschriftbare Folie zu schaffen, die mit geringem technischen Aufwand einen großen farblichen Gestaltungsspielraum bietet. Zudem sollen die positiven Eigenschaften herkömmlicher laserbeschriftbarer Folien erhalten bleiben. Das heißt, beim Beschriften mit dem Laserstrahl sollen praktisch keinerlei gesundheitsgefährdende und umweltschädigende Emissionen hervorgerufen werden, und die fertig beschrifteten Etiketten, Typenschilder etc. sollen einen großen immanenten Schutz des Schriftbildes gegenüber chemischen und mechanischen Beanspruchungen bieten, also unter anderem eine gute Beständigkeit gegen Abrieb und Ausbleichen.The invention is therefore based on the object of providing a film which can be labeled with a laser beam and which offers a great deal of color design freedom with little technical outlay. In addition, the positive properties of conventional laser-inscribable films should be retained. This means that when labeling with the laser beam, practically no health-endangering and environmentally harmful emissions are to be produced, and the fully labeled labels, type plates, etc. are intended to offer great intrinsic protection of the typeface against chemical and mechanical loads, i.e., among other things, good resistance to abrasion and Bleach.
Die Aufgabe wird durch eine mit einem Laserstrahl beschriftbare Folie gelöst, die mindestens eine für den Laserstrahl durchlässige durchgefärbte, transluzente Schutzschicht aufweist, auf deren Unterseite ein durch den Laserstrahl veränderbares Medium angeordnet ist, das mindestens zwei opake, durch den Laserstrahl ablatierbare Schichten und mindestens eine gegen den Laserstrahl resistente kontrastbildende Schicht aufweist, wobei mindestens eine der für den Laserstrahl weitgehend durchlässigen Schutzschichten durchgefärbt ist. Somit wird der Farbeindruck der durch die Schutzschicht sichtbaren Schichten von der Färbung der Schutzschicht beeinflußt. Beispielsweise erscheint der nichtablatierte Anteil einer silberweißen Metallisierung durch eine gelblich durchgefärbte Schutzschicht goldfarben.The object is achieved by a film which can be labeled with a laser beam and which has at least one colored, translucent protective layer which is permeable to the laser beam and on the underside of which a medium which can be changed by the laser beam is arranged and which has at least two opaque layers which can be ablated by the laser beam and at least one has a contrast-forming layer resistant to the laser beam, wherein at least one of the protective layers that are largely transparent to the laser beam is colored through. The color impression of the layers visible through the protective layer is thus influenced by the color of the protective layer. For example, the non-ablated portion of a silver-white metallization appears gold-colored due to a yellow-colored protective layer.
Zwischen den durch den Laserstrahl ablatierbaren Schichten ist jeweils eine transluzente, d.h. für den Laserstrahl durchlässige und transparente, durchgefärbte Schicht angeordnet. Dies führt dazu, daß sich bei ein- und derselben Folie auch abschnittsweise verschiedenfarbige Beschriftungen realisieren lassen, wobei die Schriftfarbe auch erst beim Beschriftungsvorgang selbst variiert werden kann, je nachdem, ob man an einer bestimmten Stelle keine, mehrere oder alle übereinander angeordneten ablatierbaren Schichten entfernt.Between the layers that can be ablated by the laser beam there is a translucent, i.e. arranged for the laser beam transparent and transparent, colored layer. This leads to the fact that with the same film, different colored inscriptions can be realized in sections, whereby the font color can only be varied during the inscription process itself, depending on whether one, several or all superimposed ablatable layers are removed at a certain point ,
Als vorteilhaft hat sich herausgestellt, mindestens eine der opaken, durch den Laserstrahl ablatierbaren Schichten überwiegend metallisch auszuführen. Dabei können die Metallisierungen beispielsweise auf transluzente Folien aufgedampft oder aufgesputtert sein. Vorzugsweise handelt es sich bei den metallischen Schichten um Aluminiumschichten.It has turned out to be advantageous to carry out at least one of the opaque layers, which can be ablated by the laser beam, mainly metallic. The metallizations can be deposited or sputtered onto translucent foils, for example. The metallic layers are preferably aluminum layers.
In einer weiteren Ausführungsform der Erfindung enthält mindestens eine der ablatierbaren Schichten Metalloxide, wobei auch nichtstöchiometrische Metalloxide und Mischungen aus Metallen und Metalloxiden enthalten sein können.In a further embodiment of the invention, at least one of the ablatable layers contains metal oxides, non-stoichiometric metal oxides and mixtures of metals and metal oxides also being able to be present.
In einer Weiterbildung der vorliegenden Erfindung umfaßt die kontrastbildende Schicht mehrere Bereiche unterschiedlicher Farbe.In a further development of the present invention, the contrast-forming layer comprises several areas of different colors.
In einer besonders bevorzugten Ausführungsform der vorliegenden Erfindung weist das durch den Laserstrahl veränderbare Medium an seiner Unterseite eine selbstklebende Schicht auf, wodurch sich die beschriftete Folie auf einfache Weise auf einer Unterlage anbringen läßt. Vorzugsweise ist die Folie zuvor auf einer klebstoffabweisend beschichteten Trägerbahn angeordnet, von welcher sich die Folie vor dem Applizieren auf die Unterlage abziehen läßt.In a particularly preferred embodiment of the present invention, the medium which can be changed by the laser beam has a self-adhesive layer on its underside, as a result of which the labeled film can be attached to a base in a simple manner. The film is preferably previously adhesive-repellent coated carrier web is arranged, from which the film can be removed before application to the base.
In einer weiteren vorteilhaften Ausführungsform ist die Schutzschicht an ihrer Oberseite mit einer Klebstoffschicht versehen, wodurch sie sich für Hinterglas-Anwendungen, beispielsweise in Autoheckfenstern eignet.In a further advantageous embodiment, the protective layer is provided on its upper side with an adhesive layer, which makes it suitable for rear glass applications, for example in rear-view windows.
Zusätzliche Anpassungen der visuellen Wirkung der vorliegenden Erfindung lassen sich erzielen, indem man die Schutzschicht zumindest teilweise bedruckt oder lackiert.Additional adjustments to the visual effect of the present invention can be achieved by at least partially printing or varnishing the protective layer.
In einer besonders bevorzugten Weiterbildung der vorliegenden Erfindung weist die Folie Anstanzungen auf, welche die Folie in einzelne Flächenbereiche, beispielsweise einzelne Kennzeichnungsetiketten, Typenschilder oder Plaketten, unterteilt. Die entstandenen Flächenbereiche lassen sich dann vorteilhafterweise ablösen und beispielsweise maschinell auf zu kennzeichnende Gegenstände aufbringen.In a particularly preferred development of the present invention, the film has punched holes, which subdivides the film into individual surface areas, for example individual identification labels, type plates or badges. The resulting surface areas can then advantageously be removed and, for example, mechanically applied to objects to be marked.
In einer weiteren vorteilhaften Ausgestaltung der vorliegenden Erfindung ist die Folie auf einer Unterlage anbringbar und weist zusätzliche Sicherheitsanstanzungen auf, welche unbefugtes Ablösen der, Folie von dem Untergrund ohne zumindest teilweiser Zerstörung der Folie unmöglich machen.In a further advantageous embodiment of the present invention, the film can be attached to a base and has additional security punchings which make unauthorized detachment of the film from the base impossible without at least partially destroying the film.
In einer weiteren Ausführungsform der vorliegenden Erfindung ist die Folie durch Einwirkung eines Laserstrahls in einzelne, zumindest teilweise ablösbare Flächenbereiche unterteilt.In a further embodiment of the present invention, the film is divided into individual, at least partially detachable surface areas by the action of a laser beam.
Nachstehend wird die Erfindung anhand eines schematisch dargestellten Ausführungsbeispiels näher erläutert. Die Abbildung soll den Schichtenaufbau einer erfindungsgemäßen Ausführungsform verdeutlichen, wobei die Dimensionen nicht maßstäblich widergegeben sind. Es zeigt:
- Fig.2:
- eine schematische Schnittzeichnung einer erfindungsgemäßen Folie mit zwei ablatierbaren Schichten.
- Figure 2:
- is a schematic sectional drawing of a film according to the invention with two ablatable layers.
In Fig.2 ist ein nicht maßstäblicher Schnitt senkrecht zum Schichtaufbau eines Ausführungsbeispiels der vorliegenden Erfindung dargestellt. Unterhalb der transluzenten, durchgefärbten Schutzschicht 2 ist eine ablatierbare metallische Schicht 3 angeordnet, welche über eine transparente isolierende Schicht 13 mit einer durchgefärbten transluzenten Schicht 6 verbunden ist, an deren Unterseite eine zweite ablatierbare Schicht 4 angeordnet ist. Die durchgefärbte transluzente Schicht 6 besteht zweckmäßigerweise aus Kunststoff, die zweite ablatierbare Schicht 4 aus Metall.FIG. 2 shows a section, not to scale, perpendicular to the layer structure of an exemplary embodiment of the present invention. Below the Translucent, solid-colored protective layer 2 has an ablatable metallic layer 3 which is connected via a transparent insulating layer 13 to a solid-colored translucent layer 6, on the underside of which a second ablatable layer 4 is arranged. The solid colored translucent layer 6 expediently consists of plastic, the second ablatable layer 4 of metal.
Die zweite ablatierbare Schicht 4 ist über eine transparente Verbindungsschicht 9 mit der kontrastbildenden Farbschicht 5 verbunden, die auf eine Kunststoffolie 10 aufgebracht ist. Die Schutzschicht 2 ist zweckmäßigerweise ebenfalls aus Kunststoff. An ihrer Unterseite weist die Kunststoffolie 10 eine selbstklebende Schicht 7 auf, welche auf der der Kunststoffolie gegenüberliegenden Seite mit einem, beispielsweise Teil einer durchgehenden Bahn darstellenden, Trägermaterial 8 bedeckt ist. Das Trägermaterial 8 ist durch entsprechende Behandlung, beispielsweise eine Silikonisierung, klebstoffabweisend, so daß sich die laserbeschriftbare Folie von dem Trägermaterial 8 abziehen und auf eine andere Unterlage aufkleben läßt. Wurde das Folienlaminat zuerst in einzelne Etiketten, Plaketten, Schilder etc. geschnitten oder gestanzt, so sind diese Etiketten, Plaketten, Schilder etc. einzeln vom Trägermaterial 8 ablösbar und können einfach auf verschiedenste Gegenstände aufgeklebt werden.The second ablatable layer 4 is connected via a transparent connecting layer 9 to the contrast-forming color layer 5, which is applied to a plastic film 10. The protective layer 2 is advantageously also made of plastic. On its underside, the plastic film 10 has a self-adhesive layer 7, which is covered on the side opposite the plastic film with a carrier material 8, for example part of a continuous web. The backing material 8 is adhesive-repellent by appropriate treatment, for example siliconization, so that the laser-inscribable film can be pulled off the backing material 8 and stuck onto another base. If the film laminate was first cut or punched into individual labels, plaques, signs, etc., these labels, plaques, signs, etc. can be detached individually from the carrier material 8 and can simply be stuck onto a wide variety of objects.
Mit Hilfe eines Laserstrahls 1 b, 1 c, beispielsweise von einem elektronisch nachgeführten YAG-Laser, können Buchstaben oder grafische Zeichen darstellende Flächenbereiche 11 a, 11 b der metallischen Schicht 3 durch entsprechende Wahl der Leistung und der Einwirkungszeit des Lasersstrahls 1 b, 1 c so ablatiert werden, daß die zweite ablatierbare Schicht 4 nicht mit ablatiert wird. Die ablatierten Bereiche 11 a, 11 b erscheinen in einer Farbe, die sich aus der Farbe der Metallisierung 4 mit der Farbfilterwirkung der Schutzschicht 2 und der transluzenten Schicht 6 ergibt. Die nicht ablatierten Bereiche erscheinen in einer Farbe, die sich aus der Farbe der Metallisierung 3 mit der Farbfilterwirkung der Schutzschicht 2 ergibt.With the aid of a laser beam 1 b, 1 c, for example from an electronically tracked YAG laser, areas or areas 11 a, 11 b of the metallic layer 3 that represent letters or graphic characters can be selected by appropriate selection of the power and the exposure time of the laser beam 1 b, 1 c be ablated so that the second ablatable layer 4 is not ablated. The ablated areas 11 a, 11 b appear in a color that results from the color of the metallization 4 with the color filter effect of the protective layer 2 and the translucent layer 6. The non-ablated areas appear in a color that results from the color of the metallization 3 with the color filter effect of the protective layer 2.
Mit Hilfe des Laserstrahls 1 a, 1 d des elektronisch nachgeführten YAG-Lasers können zudem Buchstaben oder grafische Zeichen darstellende, einander paarweise überdeckende Flächenbereiche 12a, 12b der metallischen Schichten 3 und 4 ablatiert werden, wenn die Leistung und Einwirkungszeit des Lasersstrahls 1 a, 1d entsprechend eingestellt wird, oder der Lasersstrahl 1 a, 1d zweimal über die entsprechenden Bereiche 12a, 1 2b geführt wird. Die Bereiche 1 2a, 1 2b erscheinen dann in einer Mischfarbe, die durch den Farbfiltereffekt der Schutzschicht 2 und der transluzenten Schicht 6 aus der Farbe der kontrastierenden Schicht 5 entsteht. Bei heller, hinreichend transparenter Färbung der Schutzschicht 2 und transluzenten Schicht 6 wird der Farbeindruck einer dunkel gefärbten Kontrastschicht 5 nur wenig bis gar nicht beeinflußt.With the help of the laser beam 1 a, 1 d of the electronically tracked YAG laser, areas or areas 12a, 12b of the metallic layers 3 and 4 which represent letters or graphic characters and overlap in pairs can also be ablated if the power and exposure time of the laser beam 1 a, 1d is set accordingly, or the laser beam 1 a, 1d twice over the corresponding Areas 12a, 1 2b is performed. The areas 1 2a, 1 2b then appear in a mixed color, which is created by the color filter effect of the protective layer 2 and the translucent layer 6 from the color of the contrasting layer 5. If the protective layer 2 and the translucent layer 6 are lightened, sufficiently transparent, the color impression of a dark colored contrast layer 5 is influenced only slightly or not at all.
Für den Fall einer gelblich durchgefärbten Schutzschicht 2, einer in hellem Cyan durchgefärbten transluzenten Schicht 6, silberweißen Metallisierungen 3, 4 und einer schwarzen Kontrastschicht 5 ergeben sich grün-metallic-farbene und schwarze Zeichen mit goldfarbenem Hintergrund. Für den Fall einer in hellem Cyan durchgefärbten Schutzschicht 2, einer gelblich durchgefärbten transluzenten Schicht 6, silberweißen Metallisierungen 3, 4 und einer schwarzen Kontrastschicht 5 ergeben sich grün-metallic-farbene und schwarze Zeichen mit cyan-metallic-farbenem Hintergrund.In the case of a yellow-colored protective layer 2, a translucent layer 6 colored in light cyan, silver-white metallizations 3, 4 and a black contrast layer 5, green-metallic-colored and black characters with a gold-colored background result. In the case of a protective layer 2 colored through in light cyan, a translucent layer 6 colored through yellow, silver-white metallizations 3, 4 and a black contrast layer 5, green-metallic-colored and black characters with a cyan-metallic-colored background result.
