Abstract

Proposed is a security element, preferably in the form of a security stripe, security thread, or a security patch, comprising a machine-readable code and an optically variable security feature, which has a visual appearance that depends on the viewing angle. The machine-readable code is a magnetic encoding, which is produced by printing at least one opaque magnetic printing ink containing magnetic pigments, with the magnetic printing ink being incorporated or applied in at least one defined code region such that the visual appearance of the optically variable security feature is determined at least in part by the at least one incorporated or applied magnetic printing ink. The optically variable security feature comprises a micro-optical micro-lens arrangement, which covers the at least one code region in which the at least one magnetic printing ink has been incorporated or applied.
