OPTICALLY VARIABLE ELEMENT

摘要

The invention relates to an optically variable element and to a method for the production thereof. In a first area, the optically variable element has at least one first color region that generates a color dependent on the angle of observation and/or the angle of illumination in the event of illumination. The first color region has two or more zones (41 to 47) arranged next to one another. The two or more zones arranged next to one another each have a width dimension and/or length dimension less than 300 µm. In at least one first zone (41) of the zones (41 to 47) of the first color region, a thin-film interference filter (15) having at least one interference layer (17) is provided. The interference layer (17) of the thin-film interference filter (15) has a first average thickness (d1) in the first zone (41). The first average thickness is selected in such a way that the thin-film interference filter (15) generates a color by means of interference in the event of illumination under at least one certain angle of observation and/or angle of illumination, which color is different from at least one color that is generated in at least one of the other zones (42 to 47) of the first color region in the event of illumination under said angle of observation and/or angle of illumination.
