Definitions

  • the present invention relates to transfer papers for sublimation printing, and more particularly but not exclusively to those printable by inkjet printing.
  • Sublimation printing is used to provide an image on a medium, such as metal, glass, plastic surface, or fabric, using sublimable inks.
  • the printing of sublimable inks can be done by direct printing of sublimable inks on the final support or by indirect printing.
  • indirect printing the inks are first printed on a paper, called transfer paper, then the image printed on the transfer paper is transferred by transfer presses to the final support. Requirement US 2008/0229962 describes such a printing process.
  • the demand EP 2965919 A1 discloses a transfer paper comprising a reservoir layer having an outer face configured to receive a sublimable ink and a barrier layer, applied to the inner face of the reservoir layer, and configured to form a barrier to the vehicle of the sublimable ink.
  • the reservoir layer may further comprise a cationic polymer in low proportion to fix the dyes of the sublimable ink to the surface of the transfer paper.
  • Requirement WO00 / 06392 describes a transfer paper comprising a barrier layer having a porosity of at most 100 ml / min.
  • WO2008 / 006434 discloses a paper comprising a layer comprising a semi-synthetic polymer with thermoplastic property.
  • Inkjet printable sublimation printing transfer papers generally comprise a barrier layer based on a hydrophilic polymer, such as carboxy methyl cellulose, starch, or polyvinyl alcohol, more or less charged with pigments with a low specific surface, such as kaolin or calcium carbonate, or with a high specific surface, such as silicas.
  • a hydrophilic polymer such as carboxy methyl cellulose, starch, or polyvinyl alcohol
  • a barrier layer based on a hydrophilic polymer leads to a long drying time, limiting the printing rates and causing mixtures of colors and smears which alter the print quality.
  • the invention aims to meet this need and it achieves it thanks to a transfer paper for sublimation printing, comprising a fibrous substrate, the transfer paper having on at least one face one or more cationic agents, deposited by a treatment. surface area on the fibrous substrate, the amount of the cationic agent (s) being greater than or equal to 8%, for example greater than or equal to 9%, or even 10%, by dry weight, of the total dry weight of the compound (s) provided by surface treatment on the fibrous substrate.

  • Cationic agents are usually used in small proportions as ink fixing agents for inkjet printing in order to retain the ink on the surface and to avoid bleeding of the ink in water.
  • a cationic agent in a higher proportion in the invention surprisingly makes it possible to ensure a good transfer by sublimation, the ink being against all expectations little retained in the transfer paper during the sublimation.
  • the transfer paper according to the invention has good printability, in particular thanks to the immobilization of the ink at the surface by the cationic agent (s).
  • the immobilization of the pigments of the ink on the surface of the fibrous substrate by the cationic agent (s) improves the optical density after transfer and limits burrs. The definition is thus improved.
