Method for producing security elements by the individualization of volume holograms and security elements produced therewith

A method for producing security elements in documents, comprising the following steps:

• (a) applying relief information on or into the upper surface of the document by printing or embossing;
• (b) after this, applying a liquid monomer-containing adhesive to the entire upper surface of the document, whereby the structure of the relief information results in an adhesive layer with different thickness distributions;
• (c) laminating a volume hologram film on top of the document surface on which the relief information is applied and which is coated with the liquid monomer-containing adhesive, wherein the volume hologram film and the document surface are not in direct contact, and after a holding time, during which the adhesive monomers have diffused into the hologram film with different intensities in areas of the document having reliefs and areas not having reliefs, respectively, whereby the difference in the monomer intensities caused the hologram to swell to different extents in different areas and have led to color change, creating a diffractive information, curing the adhesive composite so as to provide an individualized volume hologram with the holographic reproduction of the relief information on the document positioned exactly above the relief information.
