Definitions

  • the present invention relates to a metallic optic ink jet recording material, the use of a metallic optics ink jet recording material, in particular a label, photograph, poster or packaging material, and a process for producing a metallic optics ink jet recording material.
  • inkjet printers for printing on paper, foils, fabrics, etc. have been widely used not only in the industrial and office fields but also in the home field. They are characterized by very good printing results, so that not only the color and black and white printing of texts and simple illustrations is possible, but also the color printing of photos and complex, fine patterns.
  • inkjet printers minute drops of ink are ejected from a nozzle onto a medium to be printed, the production of the ink droplets being effected, for example, by a piezoelectric element or by means of a heating element.
  • aqueous inks oil-based inks, or solid inks (hot-melt inks) may be used.
  • aqueous inks are preferred and commonly used because of their manufacturing and handling advantages, as well as their odor and safety.
  • inkjet printers not only the quality of the printer, but also the quality of the medium to be printed is relevant.
  • the incident color can be well absorbed by the medium without it running in the surface of the sheet or penetrates too deep into the medium. This is particularly relevant when printing detailed graphics or photos where a high resolution, ie many dots per inch (DPI), of the print image should be achieved to get a good print image.
  • DPI dots per inch
  • the surface of the medium to be printed can be specially refined, so that the image appears shiny or dull, for example.
  • For special applications is regularly looking for new inkjet printers printable papers, which have a novel surface effect.
