Definitions

  • the subject of the present invention is a printing form.
  • gloss varnish After printing, for example by offset or flexo printing processes.
  • gloss lacquers can be present both in aqueous and in organic solution and can be cured by UV or heat.
  • a high-pressure mold in which there is a protective layer protecting against mechanical damage between a carrier layer and a paint or varnish-transferring layer.
  • This layer is intended to protect the backing from mechanical damage and consists essentially of aluminum, biaxially oriented polyester or stainless steel.
  • Such protective layers are expensive and expensive to handle.
  • 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.
  • the high-pressure form according to the invention has a filling layer 3, which is located between the lacquer-transmitting, hydrophilic layer 2 and a carrier layer 1.
  • the thickness of the paint-transferring, hydrophilic layer can therefore be reduced accordingly. Nevertheless, comparably good product properties of the printing form are achieved.
  • the thickness of the filling layer 3 is greater than the thickness of the lacquer-transferring, hydrophilic layer.
  • Typical support layers are in the range of 300 to 400 microns, typical thicknesses for the hydrophilic, paint-transferring layer are in the range of 80 to 400 microns.
  • Printing plates usually have thicknesses of 1,150, 1,350 or 1,950 ⁇ m, so that the thickness of the filling layer 3 is in the range of about 350 to 1,200 ⁇ m, preferably 550 to 950 ⁇ m.
  • FIG. 1 shows schematically the structure of the printing form according to the invention.
  • the filling layer 3 are materials having rubber or rubber elastic properties, in particular polyethylenes, silicones, nitrile rubbers, butyl rubbers, polypropylenes, polyvinyl chlorides and mixtures thereof.
  • 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).
  • the hydrophilic cover layer exhibits suitable physical properties.
