Abstract (en)
[origin: WO2020078664A1] The invention relates to an optically variable element (1a), in particular a security element (1b) and/or a decorative element (1c), preferably for security documents (1d), wherein the optically variable element (1a) comprises at least one pixel array (2) comprising two or more pixels (2aa-2dd, 2e-2f), wherein one or more pixels of the two or more pixels (2aa -2dd, 2e-2f) have one or more structures (3aa-3dd, 3e-3f), and wherein one or more structures of the one or more structures (3aa -3dd, 3e-3f) image, diffract and/or scatter incident electromagnetic radiation (6) into one or more spatial angles. The invention also relates to a security document (1d), in particular comprising one or more optically variable elements (1a), to a method for producing an optically variable element (1a), preferably a security element (1b) and/or a decorative element (1c), preferably for security documents (1d), and to a method for producing a security document (1d), preferably comprising one or more layers, preferably comprising one or more optically variable elements (1a).
