Description

Thermal Transfer Holo Patch Ribbons {A HEAT TRANSFER HOLOPETCH RIBBON}

The present invention relates to a thermal transfer holopatch ribbon, and more specifically, a protective ribbon and a hologram layer are integrally stacked on a base material, and the integrated thermal transfer holopatch ribbon provides durability while providing security functions for counterfeiting and tampering. It is about.

In the present specification, the term "HOLOPETCH" is used to mean a patch hologram ribbon formed by integrally stacking a protective ribbon and a hologram layer.

In general, in order to grant security functions to prevent forgery and tampering on identification cards such as resident registration card, driver's license, employee's card, student's card, etc. Method has been used. To this end, a method of first thermally transferring a hologram ribbon to a printed object and thermally transferring a protective ribbon thereon or first thermally transferring a protective ribbon to a printed object and then thermally transferring the holographic ribbon has been used.

The thermal transfer mechanism is to thermally transfer both the hologram ribbon and the protective ribbon to a thickness of 2 to 3 μm on a film of constant thickness. In this manner, the thickness of the hologram layer and the protective layer is limited to about 5 μm, and the thickness of the hologram layer and the protective layer is limited to actually protect the image or text printed on the lower hologram layer or the printed object. . In particular, when the characteristics of the printed material have a characteristic that each individual should carry, since the protection environment is very diverse, there is a limit to provide the appropriate durability by the conventional method as described above.

Even if you apply a variety of high-level hologram technology or other add-ons for the security of the printed material, if the protective layer does not function properly, it will have no meaning, and even the recorded information such as images and characters printed on the printed material is damaged. It will also occur if you wear.

Various methods for enhancing durability have been proposed. Mainly, the hologram layer has been proposed in terms of strengthening the protective layer while maintaining the existing transfer method. For example, there is a U.V curing method (manufactured by DataCard, Inc.) that transfers an existing thin protective layer to two layers or installs a special U.V irradiation device in a printer. On the other hand, the hologram layer is also subjected to special treatment such as curing treatment in order to impart its own durability, but mutual adhesion with the protective ribbon is the biggest problem. This is because it is difficult to harmonize the adhesive force between the hologram self-protection layer for strengthening durability and the adhesive layer of the protective ribbon. Insufficient adhesion between the hologram ribbon and the protective ribbon not only impairs durability including chemical resistance such as water resistance, alcohol resistance, plasticizer, solvent resistance, but also makes forgery and tampering very easy.

Accordingly, the present inventors have completed the present invention as a result of repeated efforts to improve the durability and to provide a security function for preventing forgery and tampering by integrally designing the hologram layer and the protective ribbon.

The purpose of the present invention is to integrally laminate the hologram layer and the protective ribbon on the substrate, to provide a security function to prevent forgery and tampering, and to reinforce the durability weakness of the protective ribbon of the conventional thermal transfer method, and An integrated thermal transfer holopatch ribbon aimed at simplifying the process is provided.
