Insbesondere ist das erfindungsgemäße Verfahren zum Dekorieren von Möbeln oder Möbelteilen geeignet.The decoration is done with dyes that represent a motif or can also be used in one color. In particular is the inventive method for decorating furniture or Suitable for furniture parts.

Die EP 0 573 676 A1 beschreibt die Verwendung eines Trägers mit "Release"-Eigenschaft zum Auftragen von Farbdekor auf ein Substrat. Bei diesem Stand der Technik wird zu diesem Zweck zunächst das Farbdekor auf einen Träger mit "Release"-Eigenschaft aufgebracht, danach über das auf den Träger aufgebrachte Farbdekor ein Lack aufgetragen, der Lack anschließend teilvernetzt und danach unter Druck und/oder erhöhter Temperatur der teilvernetzte Lack mitsamt dem Farbdekor vom Träger auf das letztlich zu dekorierende Substrat so übertragen, daß der Lack unter dem Farbdekor auf dem Substrat aufliegt. Abschließend erfolgt dort eine weitere Vernetzung des Lackes auf dem Substrat.EP 0 573 676 A1 describes the use of a carrier "Release" property for applying color decor to a Substrate. This state of the art is used for this purpose the color decor on a carrier with "release" property applied, then over the color decor applied to the carrier a varnish is applied, the varnish is then partially cross-linked and then under pressure and / or elevated temperature of the partially crosslinked Lacquer together with the color decor from the wearer towards the end decorating substrate so transferred that the paint under the Color decor rests on the substrate. Finally there a further crosslinking of the lacquer on the substrate.

Sollen dreidimensionale Gegenstände mit der "Release"-Technik farbig dekoriert werden (wobei unter einer farbigen Dekoration auch eine homogene, einfarbige Dekoration zu verstehen ist), treten insbesondere im Bereich von Kanten und auch bei kompliziert geformten dreidimensionalen Gegenstände Probleme hinsichtlich der Qualität der Dekorierung auf. Should be three-dimensional objects with the "release" technique be decorated in color (being under a colored decoration a homogeneous, single-colored decoration is also to be understood), occur particularly in the area of edges and also at complicated problems regarding molded three-dimensional objects the quality of the decoration.

Es ist bekannt, daß PVC-Folien hinsichtlich der mechanischen Eigenschaften gut zur Beschichtung von Gebrauchsgegenständen, wie z. B. Möbeln, geeignet sind. Sollen jedoch die Gegenstände farbig dekoriert werden, z. B. in der Art eines Holz-Musters oder dergleichen, so hat PVC den Nachteil, daß es schlecht bedruckbar ist. Auch führt die Verwendung von Folien zur Beschichtung von Gegenständen gemäß dem Stand der Technik nicht zu einer ästhetisch ansprechenden Dekorierung.It is known that PVC films have mechanical properties good for coating everyday items, such as e.g. B. furniture are suitable. However, the objects should be colored be decorated, e.g. B. in the manner of a wood pattern or the like, PVC has the disadvantage that it is difficult to print is. The use of foils also leads to the coating of Articles according to the prior art do not become an aesthetic appealing decoration.

Die Erfindung hat das Ziel, ein Verfahren bereitzustellen, mit dem Gegenstände so mit einer Folie beschichtet werden können, daß ein sowohl hinsichtlich der mechanischen Stabilität der Dekorierung als auch ihrer ästhetischen Wirkung gutes Ergebnis erzielt wird.The invention aims to provide a method with objects can be coated with a film that a both in terms of the mechanical stability of the decoration as well as their aesthetic effect becomes.

    Figur 1 zeigt eine Folie 10 aus ESI (siehe oben). Auf die Folie 10 ist ein Dekor 12 aus diffusionsfähigen Farbstoffmolekülen aufgetragen. Das Farbdekor 12 wird insbesondere mittels der eingangs erläuterten "Release"-Technik auf die Folie 10 aufgebracht. Da die Folie 10 aus ESI nicht ohne weiteres mit den diffundierbaren Farbstoffen bedruckbar ist, wird das farbige Dekor zunächst auf einen Träger (nicht dargestellt) mit "Release"-Eigenschaft aufgedruckt. Als Träger mit "Release"-Eigenschaft kommt insbesondere ein Polyesterfilm in Betracht. Nachdem das farbige Dekor 12 vom Polyesterfilm auf den Film 10 durch "Release"-Abpellen übertragen worden ist, wird über das Farbdekor 12 eine Grundierungsschicht 14 aufgebracht. Die Grundierungsschicht 14 bewirkt später eine Grundierung des zu dekorierenden Gegenstandes 16 (Figur 2). Als Material für die Grundierungsschicht 14 kommen insbesondere in Betracht Schmelzkleber, Thermoplaste und Klebefolien. Die Grundierungsschicht 14 kann eine Grundfarbe enthalten, mit der der Gegenstand 16 gefärbt werden soll.Figure 1 shows a film 10 made of ESI (see above). On the slide 10 is a decor 12 made of diffusible dye molecules applied. The color decor 12 is in particular by means of the input explained "release" technique applied to the film 10. Since the film 10 made of ESI is not readily compatible with the diffusible Dyes are printable, the colored decor first on a carrier (not shown) with "release" property printed on. As a carrier with "release" property a polyester film is particularly suitable. After that colored decor 12 from polyester film to film 10 through "Release" chipping has been transferred over the color decor 12 applied a primer layer 14. The primer layer 14 later causes the primer to be decorated Item 16 (Figure 2). As a material for the primer layer 14 come into consideration in particular hot melt adhesive, Thermoplastics and adhesive films. The primer layer 14 can contain a base color with which the object 16 is colored shall be.
