Definitions

  • the invention relates to a support for decals or decals made of absorbent paper with an applied barrier layer and a water or heat-soluble separating layer for one-sided reception of a removable print and / or lacquer layer.
  • a drawing or deposition pictures which are used for the decoration of ceramic objects, porcelain, glass, enamel, metallic surfaces and the like are known. They essentially consist of a water-permeable paper carrier, on which a removable, holding film is applied from a covering lacquer mask which contains the decorative image of, for example, inorganic pigments.
  • the known paper supports (DE-OS 25 51 860, corresponding to US Pat. No. 4,049,860) contain a water-soluble separating layer on which the print which can be removed later is carried out.
  • the separating layers are more or less hygroscopic, which results in a different tendency to curl, for example during storage.
  • powder color particles are then also undesirably fixed in the non-image area, which, after the transfer or transfer image has been transferred to the, for example, ceramic base, leads to undesired impurities (toning) in the non-image area.
  • the solution to this problem is based on a support for decals or decals made of absorbent paper with an applied barrier layer and water or heat-soluble separating layer for one-sided absorption of a removable printing and / or lacquer layer and is characterized in that a hydrophobic top coat is formed on the separating layer a polymerized acrylic ester is present.
  • the top coat is preferably present in a coverage of less than 5 g / m 2 , in particular in the range from about 0.5 to 2 g / m2.
  • the peel-off or push-off image can be detached from the support in accordance with the size of the paint mask covering the image, since when the separating layer separates, the top coat according to the invention disintegrates or crumbles due to its insufficient film strength. It also proves to be advantageous that the relatively thin layer of the top coat according to the invention can finally be applied from a low concentration, for example by an anilox roller or a gravure printing unit, in the ongoing coating process of the support without having to switch on an additional drying process.
  • the lock also ensures perfect printability using the offset process.
  • Polymerized acrylic esters which on the one hand have good film-forming properties and on the other hand have low strength in a thin layer, have proven to be favorable as materials for the hydrophobic top coat according to the invention, so that they can disintegrate during the separation process of the separating layer. They have the lowest possible water intake and burn, the A nassemblesprozeß accordingly, with partial takeover with the peel or Abschiebector to the subject matter residue.
  • the thin top coat also disintegrates in the process of being removed by heat and does not hinder the further workflow.
  • Homopolymers or copolymers of alkyl methacrylate with 1 to 4 carbon atoms in the alkyl group have proven to be particularly suitable among the polymerized acrylic esters. Methyl methacrylate is particularly suitable. Polymers with molecular weights in the range of about 25,000 to 350,000 can be used. Those with a medium molecular weight are advantageous. They have a viscosity of about 100 to over 3,500 m Pa's, measured in 37.5 percent by weight solution in toluene.
  • the invention is explained schematically with reference to the accompanying figure. It shows, on an enlarged scale, a schematically illustrated cross section of a carrier for decals or decals. Position 1 of the paper carrier is specified therein, on average with a mass per unit area in the range from approximately 100 to 200 g / m 2 .
  • the paper support contains a barrier layer 2 which makes one surface of the paper less porous. It can consist of surface sizing or a sealable spread, for example starch, casein, glue, alkali metal silicate, water glass, etc. with or without clay filler.
  • the presence of the barrier layer 2 prevents the excessive penetration and absorption of the material to be applied for the separating layer 3. This is selected from water-soluble mono-, oligo- or polysaccharides. In particular, dextrin is used.
  • Polymers, such as polyglycols or polyvinyl alcohols can also form the separating layer 3 alone or as a mixture.
  • the top coat according to the invention is indicated at position 4.
  • polymerized acrylic esters are used for this.
  • the top coat is designed in such a way that it reduces or delays the penetration of water into the paper from the print and / or lacquer layer side, so that the paper carrier does not warp (curl), but on the other hand it does not prevent the detachment process through the in-solution Going the interface disrupts.
  • the top coat 4 is applied as a solution to the water-soluble separating layer 3 by means of anilox roller or a gravure printing unit.
  • Low-boiling aromatics such as toluene, or conventional ketones or esters are used as solvents.
  • care must be taken to ensure that the solvent used does not attack the separating layer 3 underneath or exert any significant solution effect thereon.
  • the working viscosity of the solution to be applied results from the choice of the polymerized acrylic ester, the solvent and the solids concentration of the solution. It also depends on the chosen order method.
  • the top coat according to the invention both prevents the undesirable adhesion of the color pigments due to the reduced surface tack of the separating layer and also delays or prevents the one-sided water absorption of the paper carrier so that the paper carrier no longer tends to curl.
