  • Transfer systems resp. Transfer methods or transfer technologies are subsequently used as digital image transfer systems respectively. method resp. technologies.
  • the phosphorescent layers of the state have several disadvantages. Because the phosphorescent materials under light irradiation show only low intrinsic color, their contrast is on light background, e.g. by day or in a well-lit Space, very low. In addition, such layers usually applied by screen printing, i. every "motif" needs a corresponding template. at Combination of phosphorescent materials with conventional Colors, while eliminating the disadvantage of poor contrast on a light background with light irradiation, the application different colors but requires a corresponding Number of print templates.
  • T-shirt Become phosphorescent layers alone e.g. Applied to a bright T-shirt, they are at Hard to see for days. Such a T-shirt has little appeal for people who are not alone in the dark well visible picture resp. a visible lettering on want to have her t-shirt. Furthermore, due to the previous used a custom design not or only very limited possible. individual Design of e.g. T-shirts are in high demand. materials and methods of customization and Production of T-shirts are known, e.g. from EP 0 850 786. These state of the art T-shirts are in the Do not darken visible.
  • EP 1 031 432 discloses a personal computer Printable material known, which is a carrier layer, a phosphorescent layer and a dye receiving layer includes, wherein the phosphorescent Layer does not serve the color photograph. Because only the ink-receiving layer suitable for color absorption and the phosphorescent Layer through the ink receiving layer therethrough must remain visible, is the thickness of this layer and their degree of filling with non-transparent, porous solids limited.
  • the aim of the present invention was therefore to one with digital printing process, resp. appropriate Techniques printable resp. writable improved To provide phosphorescent material.
  • This goal was achieved through the provision a phosphorescent material containing a Carrier layer and a color receiving layer, wherein the ink receiving layer porous solid particles and a Contains binder, and which is characterized that the ink receiving layer is also a phosphorescent Contains pigment.

  • Ceramic particles used like Zeolite, these are preferably in combination with porous solid thermoplastics such as Orgasol® 3501 used.
  • porous Particles can either only be in a sublayer, preferably the sub-layer without phosphorescent Pigment, or be present in both partial layers.
  • the binder are porous.
  • Porosity can be the local fluid intake, be it ink or pigment melt, increase, resulting in a better penetration of the entire layer with pigment and clear outlines.
  • a method of manufacture a porous binder layer is e.g. from EP 0 850 786 known.
  • the binder may be a thermoplastic Resin, if necessary, after a single warming and activation is further networked or already complete crosslinked, thermosetting resin.

  • Transfer layers comprise the inventive phosphorescent Materials also include "fixed" materials, i. Materials in which the ink receptive layer on the Carrier layer remains.
  • Fixed materials are relatively uncritical and can use a variety of different backing materials provided that their flexibility and the Adhesion of the ink-receiving layer for the implementation of the Printing method is sufficient.
  • To increase liability may optionally be a surface treatment of the carrier or an adhesive layer between the backing and the ink receiving layer can be provided.

Labeling also have good transfer properties, ie, for example, good peelability of the carrier layer after heat treatment, eg ironing or hot lamination of the with the color receiving layer on a substrate, such as a textile, resting transfer material.
  • This separation of carrier and ink-receiving layer can be improved, for example, by a release layer between carrier layer and ink-receiving layer, eg a silicone layer and / or a layer of a low-melting thermoplastic polymer, wherein such a release layer of a low-melting thermoplastic polymer at the same time a protective film on a substrate form transferred color receiving layer and can stabilize it.
