Definitions

  • the invention relates to an image-receiving material for thermal dye transfer and a method for its production.
  • D2T2 dye diffusion thermal transfer
  • thermal dye transfer The principle of thermal dye transfer is that the digital image is processed with regard to the primary colors cyan, magenta, yellow and black and converted into corresponding electrical signals. These signals are forwarded to a thermal printer and converted into heat. Due to the action of heat, the dye sublimes from the donor layer of an ink ribbon (ink sheet) in contact with the receiving material and diffuses into the receiving layer.
  • ink ribbon ink sheet
  • a receiving material for thermal dye transfer generally consists of a carrier with a receiving layer applied to its front.
  • other layers are often applied to the front of the carrier. These include a. Barrier, separating, adhesive and protective layers.
  • the main component of the receiving layer is usually a thermoplastic resin that has an affinity for the dye from the ribbon.
  • thermoplastic resin that has an affinity for the dye from the ribbon.
  • linear polyesters e.g. B. polyethylene terephthalate, polybutylene terephthalate or acrylic resins, e.g. B. polymethyl methacrylate, polybutyl methacrylate, polymethylacrylate, etc.
  • polystyrene, polycarbonate, polyvinylpyrrolidone, ethyl cellulose, polysulfone and other plastics can be used as the dye-absorbing resin.
  • a polycarbonate receiving layer is applied to a polyethylene-coated base paper.
  • an underlayer is applied between the support and the receiving layer.
  • This underlayer consists of a vinylidene chloride copolymer and serves to improve the adhesion of the receiving layer to the carrier material.
  • a disadvantage of this receiver sheet is that the polycarbonate used here tends to yellow and adversely affect the transferred image over time. Another disadvantage is that both layers are applied from a solvent environment, which poses health and safety problems.
  • Patent application EP 0 261 970 describes a receiving layer which contains a linear saturated polyester as a binder and a silane copolymer coupled with silica as a release agent ("anti-blocking" additive).
  • the present invention is based on the object of proposing an image-receiving material for thermal dye transfer processes which is free from the disadvantages described above, ie is stable to heat and light and is insensitive to pressure, has good flatness and good "anti-blocking" properties.
  • the reception material further improves the color density and gradation compared to the reception sheets available on the market.
  • a receiving layer is applied to the front side of a polyolefin-coated base paper which, as the dye-receiving resin, contains a combination of at least one acrylate copolymer containing polar groups and oxidized polyethylene.
  • Combination creates a receiving sheet that not only meets the requirements listed at the beginning, but also enables a high color density of the transmitted image while increasing the gradation.
  • an acrylate copolymer is used, the polar groups of which are carboxyl, metal-bonded carboxyl and / or nitrile groups.
  • the metal-bonded carboxyl groups zinc-bonded carboxyl groups are particularly preferred.
  • Acrylonitrile and / or methacrylic acid are involved in the construction of the acrylate copolymer contained in the combination according to the invention, and the total proportion of these monomers in the copolymer is 10 to 40 mol%. In a preferred embodiment, the proportion of the monomers mentioned is 25 to 35 mol%.
  • styrene Up to 40 mol% of styrene can also be involved in the construction of the acrylate copolymer.
  • the weight ratio of acrylate copolymer / oxidized polyethylene in the combination according to the invention is 99: 1 to 30:70.

B. fluorosurfactants, dispersants, color couplers, UV stabilizers, pigments and similar auxiliaries.
  • wetting agents eg. B. fluorosurfactants, dispersants, color couplers, UV stabilizers, pigments and similar auxiliaries.
  • the receiving layer can with the help of all common application and dosing procedures such. B. roller application, engraving or nipping process on a substrate, for. B. PE coated paper can be applied.
  • the receiving layer can be applied from an aqueous medium in a single operation.
  • the application amount of the receiving layer is 0.3 - 15 g / m2, preferably 1 to 10 g / m2.
