Holographic element and process for transferring a plurality of holographic images from a polymeric support to a paper or tissue support

摘要

A paper or tissue support (31) has an adhesive layer and a metallized holographic image, wherein the metallized holographic image includes at least two holograms (32, 33), such that the first hologram (32) is visible only by non-coherent light and the second hologram (33) is visible only by coherent light. The holographic images are formed on a photosensitive element on a polymeric support by imaging steps, which include metallizing (33) the holographic images and overcoating the holographic images with an adhesive layer. Next, the metallized holographic images (33) are transferred to the paper or tissue (31) by laminating the adhesive layer to the paper or tissue (31) at a predetermined temperature and pressure, and subsequently delaminating the polymeric support from the paper or tissue (31), such that the holographic image remains on the polymer support for reuse.;The invention is appropriate for providing security wrapping papers.
