Definitions

  • the invention relates to a sheet-like transfer material for the dye-sublimation transfer process of an inkjet print image with a support and a dye-receiving layer on the front side that is slightly adhering to the receiving material during transfer. It therefore relates to a transfer paper, which is provided for printing with sublimable dyes by the inkjet printing process and from which the dyes are transferred under heat influence to a receiving material by sublimation after printing.
  • the invention also relates to the method for transferring an inkjet print image from the transfer paper according to the invention to an example textile receiving material.
  • transfer printing For printing on materials such as textiles or rigid bodies, which are difficult to print for mechanical reasons by direct printing process, offer transfer printing, in which initially printed on a flexible sheet-shaped transfer material and the printed image is transferred from this to the object to be printed.
  • a particular embodiment of such a transfer printing process is the dye sublimation process, which is described, for example, in US Pat Thompson: Printing Materials - Science and Technology (1998) on page 468 is described.
  • the image to be printed on the transfer material is applied using printing inks, which are evaporated after the drying of the print under the action of heat and imagewise on the gas phase on the final material to be printed again.
  • the sublimation inks can be advantageously applied to the transfer material by digital printing, especially the inkjet printing process, resulting in individualized and personalized prints for Example on textiles allows.
  • the transfer material on which the first printing step takes place by means of inkjet printing technology is preferably a paper transfer material.
  • a paper transfer material In the EP 1101 682 A1 is a coated paper described, which has a low air permeability on the side to be printed. This is to avoid that in the sublimation transfer step, a part of the sublimable dyes penetrates into the porous paper interior and thus lost for transfer to the final material to be printed.
  • such papers with a low porosity on the page to be printed take up the inkjet ink liquid only very slowly and lead to slow drying and bleeding of the ink on the surface and thus to an unsatisfactory print sharpness, especially at high printing speeds.
  • tacy transfer papers are products that adhere to the textiles under the transfer conditions in the sublimation process. These products are used in particular for stretchable (knitted) textiles to prevent ghosting and to reduce the reject rate in textile printing.
  • a typical application is the printing of sports textiles. Consequently, this type of adhesion involves preventing displacement of the print carrier relative to the receiving material arranged on the print substrate or vice versa.
  • thermal transfer paper is also in the DE 10 2014 116550 A1 described.
  • it proposes to use thermoplastic particles having a melting point of 35 ° C to 150 ° C having an average particle size of 0.3 to 5 ⁇ m in the thermal transfer layer. Due to the thermoplastic particles, the adhesion of the thermal sublimation paper is to be optimized when printing on flat textiles.
  • the thermal transfer layer of this document has a binder content of 55 to 80% otro and may also contain pigments. In the case of this binder fraction in the thermal transfer layer, even in the presence of pigments, a closed film-like and therefore no porous layer is present.
  • a disadvantage of the procedure described here is therefore that the drying rate is substantially lower than that when using microporous layers and also a large amount of thermoplastic particles must be used in order to obtain a noticeable adhesion effect at all. This can severely affect the print quality (line sharpness) and the transfer quality (optical densities on textile). It is also not possible with this approach to control the textile adhesion regardless of the printing and transfer quality.
  • the invention has for its object to provide a transfer paper for the inkjet printing of sublimable dyes with a fast-drying (microporous) transfer layer and excellent adhesion to textile materials.
  • a transfer material for the dye sublimation transfer method of an inkjet print image with a support and a pigment and binder-containing ink receiving layer on the front side of the transfer material wherein the ink receiving layer is porous and on the Ink receptive layer thermoplastic particles are arranged, wherein the porous ink receiving layer with the thermoplastic particles arranged thereon together has a Bendtsen air permeability of greater than 100 ml / min and wherein the thermoplastic particles have a diameter of 0.3 .mu.m to 5 .mu.m and a melting point of 60 ° C. have up to 170 ° C.
  • the transfer material may include a barrier layer disposed either on the back side of the transfer material or between the support and the porous ink receiving layer.
  • the invention further relates to a method for transferring an image to a surface by printing an inventive transfer material with an image by the inkjet printing process and transfers the image to the surface by sublimation.
  • Advantages of the invention are a lower necessary amount of thermoplastic particles, better control of tack or adhesion, little influence on the print and image transfer quality, very fast drying and independent control of the print quality and the textile adhesion.
  • this approach it is possible to achieve significantly higher adhesive forces with good print quality, if this is necessary. For example, it is possible to achieve not only adhesion to knitted (stretchable) textiles, but also to woven textiles.
  • the transfer papers according to the invention comprise a paper support having at least pressure side applied adhesive polymer particles and an underlying porous ink receiving layer.
