Description
Folie aus thermoplastischem Kunststoff mit Spiegelauflage Die Erfindung bezieht sich auf eine Folie aus thermoplastischem Kunststoff mit Spiegelauflage und mit einer diese Auflage abdeckenden Lackschicht. Die Hinterspiegelung der Lackschicht hat den Zweck, die Farbe des Lackes besonders glänzend erscheinen zu lassen. Bei Kunststoff-Folien, die Dekorationszwecken dienen oder die dazu bestimmt sind, an Stelle von Einschlagpapier verwendet zu werden, hat sich dieses bekannte Verfahren bewährt. Bei solchen Kunststoff-Folien dagegen, die im Tiefziehverfahren zu Formlingen, z. B. Hohlkörpern, verarbeitet werden, bilden sich nach dem Tiefziehen infolge von Haarrissen matte Stellen, die das Aussehen des Formlings stark beeinträchtigen. Außerdem wird der Spiegel während der Herstellung an stark beanspruchten Stellen dünn und somit durchscheinend.Foil made of thermoplastic material with mirror support The invention refers to a film made of thermoplastic with a mirror overlay and with a layer of lacquer covering this layer. The mirroring of the lacquer layer has the purpose of making the color of the paint appear particularly shiny. at Plastic films that are used for decorative purposes or that are intended to be used This known method has proven to be used in place of wrapping paper proven. In the case of such plastic films, on the other hand, which are formed into moldings in the deep-drawing process, z. B. hollow bodies, are processed, are formed after deep drawing as a result of Hairline cracks, matt areas, which greatly impair the appearance of the molding. In addition, the mirror is exposed to heavy wear and tear during manufacture thin and therefore translucent.
Die Erfindung hat eine Folie der beschriebenen Art zum Ziele, deren Spiegelglanz bei der Verformung im Tiefziehverfahren erhalten bleibt. Die Folie gemäß der Erfindung ist dadurch gekennzeichnet, daß für Tiefziehzwecke diese Folie transparent und eingefärbt ist und daß der Farbton mit der Lackschicht etwa gleich ist. Das Einfärben der Folie kann nach den bekannten Verfahren, z. B. mittels Diffusion, erfolgen. The invention has a film of the type described for the purpose Mirror finish is retained during deformation in the deep-drawing process. The foil according to the invention is characterized in that this film is used for deep-drawing purposes is transparent and colored and that the color tone is approximately the same as the paint layer is. The film can be colored according to known methods, e.g. B. by means of diffusion, take place.
Eine so eingefärbte, mit undurchsichtigem Spiegel und farbigem transparentem Lack versehene Folie gibt dem Formling nach dem Tiefziehen ein brauchbares Aussehen. Die in die Folie eingewanderten Farbteilchen verteilen sich auch nach dem Verformen noch so gleichmäßig, daß die Haarrisse im Spiegel und Lack abgedeckt werden. Soll der Formling undurchsichtig sein, so wird nach einem weiteren Merkmal der Erfindung die eingefärbte, transparente Folie auf der der Spiegelauflage abgewandten Seite mit einer möglichst gut reflektierenden, gedeckten Folie kaschiert, deren Grundton weißlich ist. Licht, das auf die Oberfläche eines Formlings aus solcher Verbundfolie fällt, wird zum Teil von der Spiegelauflage reflektiert. Durch den darüber befindlichen transparenten Farblack erhält der Formling sein leuchtendes, farbiges Aussehen. Der Rest des Lichtes, der durch die Risse in die Folie eindringt, wird hier gefärbt und von der Oberfläche der gedeckten Folie teilweise zurückgeworfen. Die Haarrisse der Oberfläche werden so farbig überdeckt. One colored in this way, with an opaque mirror and a colored transparent one Film provided with varnish gives the molding a usable appearance after deep-drawing. The color particles that have migrated into the film are also distributed after shaping so evenly that the hairline cracks in the mirror and paint are covered. Intended to the molding be opaque, so is according to a further feature of the invention the colored, transparent film on the side facing away from the mirror support laminated with a covered film that is as reflective as possible, its basic tone is whitish. Light that hits the surface of a molding made from such a composite film falls is partly reflected by the mirror support. By the one above it transparent colored varnish gives the molding its bright, colored appearance. The rest of the light that penetrates the film through the cracks is colored here and partially reflected from the surface of the covered film. The hairline cracks the surface are covered in color.
Eine gewisse Verbesserung kann noch erreicht werden, wenn man auf der Rückseite der transparenten Folie noch einen zusätzlichen Metallspiegel aufbringt, so daß die Folie beidseitig einen Spiegelbelag aufweist. Some improvement can still be achieved if you look at it applies an additional metal mirror to the back of the transparent film, so that the film has a mirror coating on both sides.
Die Zeichnung erläutert den Aufbau der Folie zur Durchführung des Erfindungsgedankens. The drawing explains the structure of the film for performing the Inventive idea.
Die Fig. 1 zeigt eine transparente, eingefärbte Folie a, welche die Spiegelschicht b aufweist. Dieser Spiegel, der z. B. durch Aufdampfen aufgebracht wird, trägt eine transparente Lackschicht c, die etwa den gleichen Farbton hat wie die eingefärbte Folie a. Fig. 1 shows a transparent, colored film a, which the Has mirror layer b. This mirror, the z. B. applied by vapor deposition has a transparent lacquer layer c, which is about the same color as the colored film a.
Die F i g. 2 zeigt die gleiche Folie, bei der eine gedeckte Folie einseitig aufkaschiertist; dist die gedeckte Folie und e die Klebeschicht, die a und d verbindet. The F i g. 2 shows the same film with a covered film is laminated on one side; dist the covered film and e the adhesive layer that a and d connects.
Die F i g. 3 zeigt die Anordnung einer zweiten Spiegelauflage f zur Verstärkung der Oberflächeneffekte. The F i g. 3 shows the arrangement of a second mirror support f for Reinforcement of the surface effects.
Haftet die Spiegelauflage b nicht auf der Folie, so können die bekannten Methoden, die Grundieren und Aktivieren der Oberfläche, Anwendung finden. If the mirror support b does not adhere to the film, the known Methods of priming and activating the surface are used.
