Magnetic screen printing ink or flexographic ink and security element printed using the same

摘要

The invention relates to a magnetic screen printing ink or flexographic ink (30) having a binder (32) and magnetically orientable, plate‑like magnetic pigments (34, 36) which are characterized by the following parameters: inherent colour, coercivity, retentivity and NIR remission. According to the invention, the screen printing ink or flexographic ink (30) contains at least two different magnetically orientable, plate‑like magnetic pigments (34, 36), which differ significantly in at least one of the characteristic parameters. The invention also relates to a security element (12) having a first print region (14) which is printed using a first magnetic screen printing ink or flexographic ink (30) of the type mentioned.
