Definitions

  • the present invention relates to a method for transferring images by means of xerocopy to substrates such as textile documents, in particular T-shirts, cups, magnetic foils, mirrors or other smooth surfaces made of metal, leather, ceramic, wood, plexiglass, cardboard or plastic by means of transfer papers.
  • the transfer paper is preferably provided with a plastic layer which adheres to the substrate when it is sealed and is detached from the transfer paper.
  • the paper must be easily detached from the plastic layer after sealing.
  • the coatings contain a wax.
  • this wax shows the serious disadvantage that it evaporates in the copier at the prevailing temperatures, sometimes up to 160 ° C., and lies on the surfaces of the device, which leads to the optics becoming dirty and the paper transport means (rollers) being reduced as a result Do not transport friction coefficients properly anymore, the copying machines are therefore very often and cumbersome to clean.
  • a method for this purpose is known, for example, from DE 39 20 864 A1, wherein a xerocopy is produced on a coated paper and this is ironed onto the fabric.
  • the coating consists of three layers, it consists of a polyethylene (copolymer) layer, onto which a hardness layer is applied by screen printing and then a stabilizer layer is applied by screen printing.
  • a polyethylene (copolymer) layer onto which a hardness layer is applied by screen printing and then a stabilizer layer is applied by screen printing.
  • a stabilizer layer is applied by screen printing.
  • the disadvantage of this procedure is the very complex coating by extrusion of the base layer and after curing by screen printing each of the two other essential layers.
  • Another disadvantage of such printed fabrics is that the prints fade after only a few washes. In addition, the print quality is not satisfactory.
  • DE 40 24 419 A1 describes a print carrier for the same purposes as described here. This consists of two polymer layers applied to a carrier paper, a first rubber layer as a melt coating and a second layer made of polyethylene or polyacrylate lying above it. Detaching the paper after applying pressure to the textile requires keeping the paper at the melting temperature of the rubber. Although wax is not used as a release agent here, since the rubber bonds very well to the paper, the removal process may need to be heated (see e.g. Claim 19) in order to maintain the high temperature of 150 to 220 ° C required for this.
  • DE 26 14 078 C2 discloses a hot printing film consisting of a carrier and an EVA copolymer coating in a mixture with a tackifier and wax in a single-layer coating on a carrier together with pigment. This material does not serve the purpose of xerocopying prints and would have the disadvantages outlined above because of the evaporation of wax.
  • DE 39 42 021 A1 uses a single-layer coating for the same purposes.
  • paraffin is added to the plastic layer and, if necessary, additionally paper coated with silicone is used, which has exactly the above disadvantages.
  • DE 39 01 340 C2 describes heat-sensitive image transfer and recording materials for use in computer printers.
  • a heat-meltable layer of paint is melted over a thermal head, transferred to a paper and assembled there into an image.
  • the coating is on an ink ribbon and, in order to improve the image quality, should have a rubber as a release layer which should be free from paraffin and, above it, a heat-melting ink layer composed of colorant and resin component.
  • an applied image is not taken over by a carrier over the entire surface, but rather is put together on the paper after individual points have been removed from the ribbon.
  • the object of the present invention is therefore to create a method and a transfer paper which contain images on print originals.
  • Xerocopy can be transferred to substrates such as textile underlays, in particular T-shirts, cups, magnetic foils, mirrors or other smooth surfaces made of metal, leather, ceramic, wood, plexiglass, cardboard or plastic by means of transfer papers, both in terms of quality and washability
  • substrates such as textile underlays, in particular T-shirts, cups, magnetic foils, mirrors or other smooth surfaces made of metal, leather, ceramic, wood, plexiglass, cardboard or plastic
  • transfer papers both in terms of quality and washability
  • the transferred images meet high demands, but at the same time do not cause the previously unavoidable contamination of the copier.
  • Either only the toner from the xerography or also part or all of the plastic coating of the transfer paper should be able to be transferred.
  • the transfer papers according to the invention consist of machine-smooth papers suitable for xerocopiers with basis weights of z. B. 80-150, preferably 90-100 g / m 2 , which are coated on one side with polyolefins or polyolefin copolymers with a layer thickness of 20-50 g / m 2 , preferably 25-40 g / m 2 .
  • the polyolefins used are, for example, LDPE, EVA with 7-28%, preferably 7-15% VA, ethylene-acrylic acid copolymers or ethylene-methyl acrylate copolymers with 5-12% acrylic acid, ethylene-butyl-acrylate copolymers with 5-20% acrylate, which have a melt index according to ASTM-D-1238 (MFI) of 3.5-22, preferably 7-15 g / 10 min at 2.16 kg / 190 ° C.
  • MFI melt index according to ASTM-D-1238
  • the plastic coating should have a limited adhesion of ⁇ 2 N / 15 mm to the backing paper in the cold so that it can be separated therefrom after the sealing process, on the other hand it should have good adhesion (stickiness) at temperatures of> 80 ° C have a Vyer softening point according to ASTM D 15025 of 70 - 180 ° C so that they do not adhere to the contours of the substrate during sealing, have good adhesion to the toners at the usual xerography temperatures, without causing it to surface mixing comes.
  • high temperature cohesion should be lower than adhesion to the substrate and substrate.
  • the desired image can be applied to the transfer paper thus produced in all commercially available xerocopiers, the toners being commercially available from the corresponding color pigments in a plastic matrix, usually made of polyester with a melting range of e.g. B. 80 - 120 ° C, and auxiliaries exist.
  • This copy can now be pressed onto the substrate at temperatures of 80 - 200 ° C.
  • a cohesive break occurs in the polymer layer, so that parts of the polymer with the toner adhere to the substrate, and some adhere to the paper, so that a very thin flexible Plastic layer remains on the substrate.
  • This is particularly advantageous for textile surfaces that have high adhesiveness for washing resistance. If the detachment takes place at medium temperatures up to room temperature, remains on non-absorbent surfaces of the substrate, e.g. B. glass, ceramic, metal, plastic only the toner on the substrate back and paper and polymer coating are removed together.
  • the paper leads to the desired image properties mentioned above.
  • the paper has the advantage over the known transfer papers that it can be produced in only one coating process, since the separating layer and sealing layer are one.
