Functional Element, A Method For Producing A Functional Element, And A Product
Patent No. EP4347271 (titled "Functional Element, A Method For Producing A Functional Element, And A Product") was filed by OVD Kinegram on May 30, 2022. The application was issued on Oct 9, 2024.
Patent Summary
Functional element with novel optical effects based on asymmetric plasmonic structures that exhibit distinct color impressions at different angles of incidence, making them resistant to counterfeiting and difficult to replicate using conventional printing techniques. The element features a metallized relief structure with an asymmetric profile shape that generates a plasmon resonance, producing a stable color impression that remains consistent over a wide range of viewing angles. The structure can be combined with additional features such as microlens grids, microimages, and moiré patterns to create complex optical effects.
