Abstract

A relief printing medium has a hydrophilic lacquer transfer layer (2).

Description

Gegenstand der vorliegenden Erfindung ist eine Hochdruckform mit einer hydrophilen farb- oder lackübertragenden Schicht gemäß Anspruch 1, ein Verfahren zur Herstellung dieser Hochdruckform sowie die Verwendung der erfindungsgemäßen Hochdruckform.The present invention relates to a high-pressure mold with a hydrophilic paint or varnish transfer layer according to Claim 1, a method for producing this high pressure mold and the use of the high pressure mold according to the invention.

Zum Schutz oder zur Veredelung von Oberflächen können diese nach der Bedruckung zum Beispiel durch Offset- oder Flexo-Druckver­ fahren mit einem Glanzlack versehen werden. Diese Glanzlacke können sowohl in wäßriger als auch in organischer Lösung vor­ liegen und können durch UV oder Wärme gehärtet werden.To protect or refine surfaces, these can be printing, for example by offset or flexo printing drive with a gloss varnish. These gloss paints can be in both aqueous and organic solution lie and can be cured by UV or heat.

Die Lacke werden gemäß Stand der Technik zumeist mit Hochdruck­ formen übertragen, wie sie sonst zur Farbübertragung eingesetzt werden. Diese Hochdruckformen haben eine farb- oder lacküber­ tragende Schicht, die für die Übertragung von Druckfarben ent­ wickelt wurde. Bei der Übertragung von Lacken ergibt sich das Problem, daß diese Schicht die Lacke nur in einem begrenzten Umfang aufnimmt. Häufig werden beim Auftragen des Lackes Druck­ farben des vorherigen Druckvorgangs wieder von der Oberfläche gelöst und durch die der Hochdruckform verschleppt.According to the state of the art, the lacquers are usually applied at high pressure transfer forms, as they are used for color transfer become. These high pressure forms have a color or varnish over load-bearing layer, which is used for the transfer of printing inks was wrapped. This results from the transfer of paints Problem that this layer only limited the varnishes Picks up scope. Pressure is often applied when the varnish is applied colors of the previous printing process from the surface solved and carried over by the high pressure mold.

Aufgabe der vorliegenden Erfindung war es somit, eine Hoch­ druckform zu entwickeln, die sich insbesondere für die Über­ tragung von Lacken eignet und dabei die genannten Nachteile des Standes der Technik überwindet.The object of the present invention was therefore a high to develop printing form that is particularly suitable for the over wearing paints and thereby the disadvantages of State of the art overcomes.

Die Aufgabe wird gelöst durch eine Hochdruckform gemäß Anspruch 1, ein Verfahren zur Herstellung der Hochdruckform gemaß An­ spruch 5 sowie die Verwendung der Hochdruckform für die Über­ tragung von Lacken gemäß Anspruch 6. Die weiteren Ansprüche stellen bevorzugte Ausführungsformen dar.The object is achieved by a high-pressure mold according to claim 1, a method for producing the high-pressure mold according to Proverb 5 and the use of the high pressure form for the over  wearing paints according to claim 6. The further claims represent preferred embodiments.

Die Fig. 1 zeigt schematisch den Aufbau der erfindungsgemäßen Hochdruckform. Fig. 1 shows schematically the structure of the high pressure mold according to the invention.

Die erfindungsgemäße Hochdruckform besitzt eine Trägerschicht 1 und eine lackübertragende Schicht 2, wobei die lackübertragen­ de Schicht 2 hydrophil ist. Bevorzugte Materialien für die lackübertragende Schicht 2 sind Polyurethane oder urethanmodifi­ zierte Epoxidharz-Mischungen, da diese geeignete hydrophile Oberflächen ergeben. Darüber hinaus kann die lackübertragende Schicht 2 Polyether, aromatisch Polyether oder Polyetherpolyole enthalten.The high-pressure mold according to the invention has a carrier layer 1 and a paint-transferring layer 2 , the paint-transferring layer 2 being hydrophilic. Preferred materials for the paint-transferring layer 2 are polyurethanes or urethane-modified epoxy resin mixtures, since these result in suitable hydrophilic surfaces. In addition, the lacquer-transferring layer 2 may contain polyethers, aromatic polyethers or polyether polyols.

Je nach verwendeter Druckmaschine kann die Hochdruckform eine Platte oder ein Tuch sein.Depending on the printing press used, the high-pressure form can be a Plate or cloth.

Das Verfahren zur Herstellung der erfindungsgemäßen Hochdruck­ form ist gekennzeichnet durch die Auftragung einer Mischung von aromatischen und aliphatischen Polyetherpolyolen, Diisocyanaten oder Epoxidharzen auf eine Trägerschicht 1 und Polymerisieren dieser Schichten in einem geeigneten Verfahren, das beispiels­ weise eine Wärmetrocknung oder eine UV-Härtung sein kann.The process for producing the high-pressure form according to the invention is characterized by the application of a mixture of aromatic and aliphatic polyether polyols, diisocyanates or epoxy resins to a carrier layer 1 and polymerizing these layers in a suitable process, which can be, for example, heat drying or UV curing.

Die erfindungsgemäßen Hochdruckformen eignen sich insbesondere zur Auftragung von Lacken innerhalb oder im Anschluß an Flexo- und Offset-Prozesse zur Veredelung des Druckproduktes. Bevor­ zugterweise können die Lacke dazu in wäßriger Lösung vorliegen.The high-pressure molds according to the invention are particularly suitable for the application of lacquers within or following Flexo and Offset processes for finishing the printed product. Before For this purpose, the lacquers can be present in aqueous solution.
