- the filling layer consists of at least 50% by weight of these substances, more preferably at least 70% by weight and most preferably at least 80% by weight.
- Suitable materials for the carrier layer are in particular polyethylene terephthalate, polycarbonate, aluminum and stainless steel.
- Preferred materials for the paint-transferring layer 2 are polyurethanes, urethane-modified epoxy resins, silicones, modified silicones or mixtures thereof, since these give suitable hydrophilic surfaces.
- the paint-transferring layer 2 may contain polyethers, aromatic polyethers or polyether polyols.
- Corresponding layers preferably have a Shore (A) hardness of 40 to 90 (DIN 53505) and a surface roughness of Ra 0.05 to 5.0 microns and / or Rz 0.5 to 10 microns.
- the hydrophilic layer preferably has surface energies ⁇ 35, preferably ⁇ 40, more preferably ⁇ 45 mN / m.
- the high-pressure mold can be a plate (metal and metal-plastic composite) or a cloth (film or foil laminate).
- the printing plates of the invention are particularly suitable for the application of paints within or following flexo and offset processes for finishing the printed product.
- the paints may preferably be in aqueous solution for this purpose. It may also be dispersions and / or emulsions.
- the printing plates according to the invention can be produced by a method in which a filling layer 3 is applied to a carrier layer 1 and a paint-transferring, hydrophilic layer 2 is applied to the filling layer 3.
- Suitable methods for this purpose are coating, laminating, laminating and coextruding.
- the filling layer can be laminated onto the carrier layer with a suitable adhesive system, onto which the hydrophilic coating-transferring layer is then glued.
- the hydrophilic cover layer and the filling layer can be coextruded onto the carrier layer.
- a triple coextrusion of support layer, filling layer and hydrophilic cover layer is possible.
- the invention is further illustrated by the following example.
- a carrier layer of polyethylene terephthalate (Mylar A 350 microns, Fa. DuPont) is applied via a suitable binder system (Henkel Liofol UR 2780) a soft PVC film (700 microns thickness) and on this one Polyurethane film with a thickness of 80 to 100 .mu.m laminated with an adhesive system suitable for PVC-PU bonding (Henkel Liofol UR 2780).

Abstract
Description
Gegenstand der vorliegenden Erfindung ist eine Druckform.The subject of the present invention is a printing form.
Zum Schutz oder zur Veredelung von Oberflächen können diese nach der Bedruckung zum Beispiel durch Offset- oder Flexo-Druckverfahren mit einem Glanzlack versehen werden. Diese Glanzlacke können sowohl in wässriger als auch in organischer Lösung vorliegen und können durch UV oder Wärme gehärtet werden.For the protection or refinement of surfaces, they can be provided with a gloss varnish after printing, for example by offset or flexo printing processes. These gloss lacquers can be present both in aqueous and in organic solution and can be cured by UV or heat.

Diese bekannte Hochdruckform für Lacke hat den Nachteil, dass die hochwertigen lackübertragenden Schichten in Abhängigkeit von der benötigten Stärke der Druckform schwierig herzustellen sind und die Handhabung entsprechend dicker Polyurethanschichten schwierig ist.This known high-pressure form for paints has the disadvantage that the high-quality paint-transferring layers are difficult to prepare depending on the required thickness of the printing plate and the handling of correspondingly thicker polyurethane layers is difficult.
Aufgabe der vorliegenden Erfindung war es daher, eine Druckform bereit zu stellen, die mit der oben genannten Druckform vergleichbare lackübertragende Eigenschaften aufweist, jedoch eine einfachere Herstellung erlaubt.It was therefore an object of the present invention to provide a printing forme that has comparable paint-transferring properties with the above-mentioned printing form, but allows easier production.
Überraschenderweise wurde nun gefunden, dass die Aufgabe gelöst wird durch eine Druckform mit den Merkmalen des Patentanspruchs 1.Surprisingly, it has now been found that the object is achieved by a printing forme having the features of
Die erfindungsgemäße Hochdruckform weist eine Füllschicht 3 auf, die sich zwischen der lackübertragenden, hydrophilen Schicht 2 und einer Trägerschicht 1 befindet. Die Dicke der lackübertragenden, hydrophilen Schicht kann daher entsprechend verringert werden. Trotzdem werden vergleichbar gute Produkteigenschaften der Druckform erreicht.The high-pressure form according to the invention has a
Typischerweise ist bei der erfindungsgemäß hergestellten Druckform die Dicke der Füllschicht 3 größer als die Dicke der lackübertagenden, hydrophilen Schicht. Typischen Trägerschichten liegen im Bereich von 300 bis 400 µm, typische Stärken für die hydrophile, lackübertragende Schicht liegen im Bereich von 80 bis 400 µm. Druckformen haben üblicherweise Stärken von 1.150, 1.350 oder 1.950 µm, so dass die Stärke der Füllschicht 3 im Bereich von ca. 350 bis 1.200 µm, bevorzugt 550 bis 950 µm liegt.Typically, in the case of the printing form produced according to the invention, the thickness of the
