Multilayer Body With Microlens Arrangement

Patent No. EP1979768 (titled "Multilayer Body With Microlens Arrangement") was filed by OVD Kinegram on Jan 16, 2007. The application was issued on Feb 16, 2022.

Patent Summary

Multi-layer body with microlens arrangement for optical security elements, comprising a first layer with microlenses, a second layer with a micropattern of opaque and transparent areas, and a third layer with a microlens array. The microlenses in the first layer selectively enlarge the micropattern pixels, creating a large-scale image that appears homogeneous in gray value. The micropattern is formed by alternating opaque and transparent areas, which are enlarged by the microlenses to create a unique optical effect. The microlens array in the third layer can be designed to create different optical effects when viewed from the front and rear sides, making the multi-layer body difficult to counterfeit.
