Definitions

  • the invention relates to a method for producing a color changeable synthetic resin surface or paint surface according to claim 1, a material according to claim 13, a decorative paper according to claim 14 and a finish film according to claim 15.
  • Decorative surfaces of synthetic resin or paint are well known and are used for example in floor coverings, wall coverings, ceiling coverings or furniture surfaces. These have a decorative layer that includes a paper with a printed decor or a painted on a background decor. On the decorative layer usually a protective layer is arranged, which is formed either as buchharzge impregnated overlay or lacquer layer. In addition, it is known to provide the Oberflä surface with a structure decor, which may be, for example, embossed or painted. The layers arranged above the decor are at least semi-transparent so that the viewer can perceive the decor.
  • the disadvantage is that the color design of such surfaces can be influenced in retrospect hardly.
  • the end user individu elle colored surface design, as it is achieved for example in solid wood by pickling the surfaces, is no longer possible with such synthetic resin and paint surfaces.
  • the invention is therefore based on the object mattezu provide a decorative surface that changes particularly simple in their color of the end user who can and which is particularly inexpensive and durable.
  • the invention solves the problem by means of a method having the features of claim 1.
  • Advantageous further developments of the invention are in the dependent claims specified. In this case, all the features described in principle, in isolation or in any combination object of the invention, regardless of their summary in the entitlements or their relationship.
  • the method according to the invention for producing a color-changeable resin surface or lacquer surface comprises the steps of providing a carrier layer with a bottom side and a top side, core impregnations of the carrier layer with a liquid impregnating agent without pickling additive, at least drying of the impregnated carrier layer, applications of a layer of a coating agent the upper side of the carrier layer, drying the at least one coating agent layer, bonding the carrier layer to a material, wherein the one layer hardens during drying and / or bonding on the upper side to an open-pored, at least largely transparent layer.
  • the carrier layer has a decorative print which is printed on the upper side of the carrier layer.
  • the decor can show structures of a décor.
  • the decor is, for example, wood grains, stone grains, stone decors, tile decors or fantasy decors dar.
  • the decor can be used as a colored decor, Decor be designed in shades of gray or even black and white decor.
  • the decor is so well through the impregnant and through the one layer still visible to the viewer, so that both the impregnating agent and the one layer are at least semi-transparent, preferably completely transparent. Even after the Bei zen, ie, after changing the color the printed on the support layer decor is retained and visible, but it changes the overall hue of the resin surface or paint surface.
  • the inventive surface it is possible with the inventive surface to make a bright overall impression of the synthetic resin / lacquer surface, which is produced by a light-on-itself printed decor, for example, dark by means of a dark stain.
  • the applied dye color pigments
  • color changeable is understood to mean that the overall color impression of the synthetic resin surface which is predetermined by the decorative imprint on the carrier layer
  • che / paint surface is subsequently changed individually via an additional color input into the cured coating agent layer.
  • the subsequent change for example, be carried out industrially, according to an industrially carried out staining of wood veneer or solid wood.
  • the inventive color changeable decor surface also offers the possibility, only at a later date, d. H. in the post-industrial manufacturing sector, for example, by a mounting craftsman or the end user to perform a color change. Due to the fact that the layer of the coating composition is mostly worn over the entire surface, there is also the possibility of performing the color adjustment either also over the entire surface or even only on partial surfaces. Thus, just by the end user very individual color designs of Kunststoffharzoberflä
  • the decorative structures produced by the printed decor preferably remain visible, only the basic color tone of the synthetic resin surface / lacquer surface is changed again via the color change. This results in an extremely high level of individualization due to the respective end consumer possible.
  • Existing structure patterns (3-D surfaces), ie textured surfaces, are also retained because the layer of coating material replicates the 3-D structures and the color pigments penetrate into the surface.
  • their optical effect is also enhanced by the stain.
