Abstract: Security element transfer materials for transferring security elements have a microoptical authenticity feature to an article of value. The microoptical authenticity features create an optical effect by interaction of a first microoptical arrangement having focusing elements with a second microoptical arrangement having micromotif elements. The security element transfer material has a temporary carrier in the form of a layer composite material. The temporary carrier consists of a first temporary carrier substrate and a second temporary carrier substrate, which may be inextricably adhesive-bonded by means of an adhesive layer. The outline shapes of the security elements to be transferred are incised or have been precut. The second temporary carrier substrate is not cut, such that the temporary carrier can be separated off as a complete carrier layer composite. A permanent carrier is bonded inextricably to the microlenses. A transfer adhesive enables adhesion to the final substrate of the article of value.

Abstract: A security element is arranged to safeguard valuable articles, featuring a motif layer based on a liquid-crystal material that forms a latent motif. The security element includes a first embossing varnish layer on a carrier film, with a motif layer partly on this varnish, based on nematic liquid crystals. A second embossing varnish layer covers the surface. The facing surface of the first varnish has an embossing with at least two regions featuring different alignment structures, creating a second latent motif. These alignment structures include an aperiodic grating with varying grid spacing. The motif layer, forming a first latent motif, overlaps the second latent motif regions. The nematic liquid-crystal material is aligned by the motif-forming regions, producing a discernible motif when viewed through a polarizer. The second varnish layer also has an embossing for a micro-optical relief structure and reflection-enhancing coating.
