Definitions

  • the present invention relates to a high resolution coating process. It also relates to products which are transparent to visible light. allowing to filter a certain range of electromagnetic wavelengths.
  • a coating according to these methods is generally total, sometimes partial, but none of these coatings makes it possible to produce patterns presenting high resolution.
  • US Patent 5,721,007 describes a process in which a support is coated a metal layer; an electrically insulating varnish is printed on high resolution on a first part of the coated support; one or more metallic layers are deposited on a second part of the support, i.e. the part of the support not covered by the varnish, by electrolysis so as to form the conductive circuits of the circuit; the electrically insulating mask is removed in order to be able to engrave the coating of the support not covered by the layer or the metallic layers deposited on the support between the varnish.
  • This method is eg used for the manufacture of electric circuits, in particular for the manufacture of flat cables. Although this method allows printing to high resolution, it does not allow a metallic deposit on the varnish.
  • the object of the present invention is therefore to propose a manufacturing process a multilayer substrate having high resolution patterns and allowing a metallic deposit on the varnish.
  • the varnish is a loaded varnish.
  • the loaded varnish not only protects in specific places the support but also to carry out a metallic deposit later on the varnish charge.
  • Printing a high-resolution varnish on a support creates fine and high resolution patterns on this support.
  • This process is independent of the support and the method of coating the support. In principle, this process is applicable to any medium
  • the support Before printing, the support can be coated with a layer which includes preferably metal.
  • the loaded varnish may for example include conductive materials and / or barrier materials to respectively filter the waves electromagnetic.
  • the material forming a barrier to respectively filtering electromagnetic waves preferably absorbs and / or reflects at least part of the electromagnetic waves.
  • the treatment of the coated support by electrolysis advantageously comprises electrolytic etching of the coating on the unprinted part of the support coating.
  • the support is subjected to a deposit electrolytic on the conductive printed part after washing and drying.
  • Support treatment by electrolysis includes electrolytic deposition one or more metals or their alloys on the printed part of the support.
  • the printing of the varnish on the support is preferably carried out by gravure printing.

  • the aqueous electrolyte advantageously comprises a mineral acid and its salt or a mineral base and its salt, preferably NaOH + concentrated NaCI at 10%.
  • the electrolyte is chosen in such a way that the products released in aqueous phase by electrolysis attack metallic coating with a mixture of the acid type and its salts or with an alkaline and its salts halogens.
  • the reflection and transmission rates can vary from 0 to 100% while the absorption rate can vary from 0 to 50%.
  • the electrolytic deposition is preferably carried out by electrolysis of one or several metals and / or their alloy, by dissolving a soluble electrode containing at least the metal or metals of the electrode.
  • the metallic deposit or successive metallic deposits allow to create drawings with high resolution and high precision on a support.
  • the products resulting from the process described above may have characteristics useful, especially for uses in the wave field electromagnetic, especially in the microwave field.
  • the process makes it possible to obtain multilayer products having characteristics of reflection, transmission and absorption of electromagnetic radiation very specific incidents.
  • radiation electromagnetic incident on the product can be transmitted at a rate of 0 to 100%, reflected at a rate of 0 to 100% and / or absorbed at a rate of 0 to 50%.
  • the use of such products is very diverse; they can for example be used as a filter for electromagnetic radiation, these filters being transparent in visible light.

  • the amount of energy absorbed, transmitted or reflected varies according to the importance and the distribution of the coating applied to the film. Below a threshold predetermined, the transmitted energy is greater than the reflected energy, beyond of this threshold, the transmitted energy is lower than the reflected energy.
  • the method also makes it possible to create multilayer products.
  • On a first metallic deposit you can deposit a second metallic deposit by ironing the support through the printing station and the processing station.
