Abstract

A pattern of an original document is transferred onto a substrate, for example a metal plate, with the aid of an intermediate substrate which is a laser copy of the original document. The metal plate is provided on one surface with a layer of lacquer which is dried at a raised temperature. Because of the application of heat and pressure, the pattern-forming material penetrates into the layer of lacquer softened thereby, which subsequently hardens. A weather-proof and scratch-proof copy of the original document is produced.

Description

Die Erfindung betrifft ein Verfahren zum Übertragen von Motiven von einer Originalvorlage auf einen Träger unter Verwendung eines Zwischenträgers gemäß dem Oberbegriff des Anspruches 1.The invention relates to a method for transferring motifs from an original template to a carrier using an intermediate carrier according to the preamble of claim 1.

Aus der DE-OS 41 18 922 ist ein Verfahren zum Übertragen von Motiven bekannt, bei dem das auf einer Originalvorlage befindliche Motiv auf einen Zwischenträger kopiert wird, wobei das auf den Zwischenträger übertragene Motiv aus einem Material, z.B. Toner besteht, und das motivbildende Material während eines bestimmten Zeitraumes durch Wärme und unter zusätzlicher gleichzeitiger Aufbringung von Druck ohne Veränderung seiner Struktur auf den Träger übertragen wird. Mit diesem Verfahren können Motive auf jegliche Art von Trägern übertragen werden, jedoch haftet diesen der Nachteil an, daß die übertragenen Motive nicht witterungsbeständig und kratzfest sind.From DE-OS 41 18 922 a method for transferring motifs is known, in which the motif on an original template is copied onto an intermediate carrier, the motif transferred onto the intermediate carrier being made of a material, e.g. Toner exists, and the motif-forming material is transferred to the carrier during a certain period of time by heat and with additional simultaneous application of pressure without changing its structure. With this method, motifs can be transferred to any type of carrier, but they have the disadvantage that the transferred motifs are not weatherproof and scratch-resistant.

Hier will die Erfindung Abhilfe schaffen. Die Erfindung wie sie in den Ansprüchen gekennzeichnet ist, löst die Aufgabe ein Verfahren zum Übertragen von Motiven zu schaffen, mit dem eine einfache und kostengünstige Übertragung von Motiven in witterungsbeständiger und kratzfester Ausführung gewährleistet ist.The invention seeks to remedy this. The invention as characterized in the claims solves the problem of creating a method for transferring motifs with which a simple and inexpensive transfer of motifs weather-proof and scratch-resistant design is guaranteed.

Durch die gleichzeitige Anwendung von Wärme und Druck dringt das motivbildende Material in die durch Wärme erweichte Schicht ein und es wird eine geschlossene Oberflächenschicht gebildet. Nachfolgend wird anhand von Ausführungsbeispielen die Erfindung erläutert.Through the simultaneous application of heat and pressure, the motif-forming material penetrates the layer softened by heat and a closed surface layer is formed. The invention is explained below on the basis of exemplary embodiments.

Beispiel 1example 1

Ein auf einer Fotografie vorhandener Schriftzug soll auf eine Metallplatte übertragen werden.A lettering on a photograph should be transferred to a metal plate.

In einem ersten Schritt wird die Metallplatte auf einer Oberfläche mit einer Schicht aus einem wäßrigen, blei- und chromatfreiem Lack auf Vinyl-Copolymerharzbasis (Farbe) versehen und getrocknet.In a first step, the metal plate is provided on one surface with a layer of an aqueous, lead and chromate-free lacquer based on vinyl copolymer resin (paint) and dried.

In einem zweiten Schritt wird der Schriftzug in einem an sich bekannten Laserkopiergerät auf eine Folie kopiert, die den Zwischenträger bildet.In a second step, the lettering is copied onto a film in a laser copier known per se, which forms the intermediate carrier.

In einem dritten Schritt wird die Folie mit schriftzugbildenden Toner auf die Oberfläche der beschichteten Metallplatte aufgelegt. Diese Anordnung wird danach während eines bestimmten Zeitraumes, der im Bereich von 3 - 60 s liegt, einem Druck von ca. 5 - 70 N/cm2 und einer bestimmten Temperatur ausgesetzt, die zwischen 95 und 115 Grad Celsius liegt, um den schriftzugbildenden Toner von der Folie in die Lackschicht zu übertragen. Bei diesem Vorgang wird die Lackschicht zu Beginn des Vorganges erweicht, so daß die Adhäsion der Lackpartikel verändert wird und die Poren sich öffnen, wodurch der Toner in die Lackschicht eindringt.In a third step, the film with lettering-forming toner is placed on the surface of the coated metal plate. This arrangement is then subjected to a pressure of approx. 5 - 70 N / cm 2 and a specific temperature, which is between 95 and 115 degrees Celsius, around the lettering-forming toner for a certain period of time, which is in the range from 3 to 60 s to transfer the film into the lacquer layer. In this process, the lacquer layer is softened at the beginning of the process, so that the adhesion of the lacquer particles is changed and the pores open, whereby the toner penetrates into the lacquer layer.

Dabei tritt keine Änderung in der Struktur und Form des Schriftzuges auf. Aufgrund der zugeführten Wärme härtet die Lackschicht nachfolgend aus. Das Resultat ist eine den Schriftzug enthaltende ausgehärtete Lackschicht, die witterungsbeständig und kratzfest ist. Das vorstehend beschriebene Verfahren wird auf dem Anlagesystem durchgeführt, das in der DE-OS 41 18 922 beschrieben ist und wird daher nicht ausführlich beschrieben.There is no change in the structure and form of the lettering. Due to the heat supplied, the paint layer subsequently hardens. The result is a hardened lacquer layer containing the lettering, which is weather-resistant and scratch-resistant. The method described above is carried out on the system that is described in DE-OS 41 18 922 and is therefore not described in detail.

Beispiel 2Example 2

Ein auf einem Papierbogen vorhandener Schriftzug soll auf eine Metallplatte übertagen werden.An existing lettering on a sheet of paper should be transferred to a metal plate.

In einem ersten Schritt wird die Metallplatte auf einer Oberfläche mit einer Schicht aus waßerlöslichem Lack auf silikonmodifizierter Polyesterbasis aufgebracht und anschliessend bei ca. 140 Grad Celsius getrocknet. Die nachfolgenden Schritte 2 und 3 werden gleich wie die Schritte 1 und 2 im Beispiel 1 ausgeführt. In einem vierten Schritt die das motivbildende Material enthaltende Lackschicht bei min. 160 Grad Celsius ausgehärtet.In a first step, the metal plate is applied to a surface with a layer of water-soluble varnish on a silicone-modified polyester base and then dried at approx. 140 degrees Celsius. The following steps 2 and 3 are carried out in the same way as steps 1 and 2 in example 1. In a fourth step, the lacquer layer containing the motif-forming material at min. Cured 160 degrees Celsius.
