Abstract

See full text

The invention relates to an optically variable element as well as a method for the production thereof. In a first area the optically variable element has at least one first color region which in the event of illumination generates a color dependent on the angle of observation and/or angle of illumination. The first color region has two or more zones (41 to 47) arranged next to each other. The two or more zones arranged next to each other have in each case a width and/or length dimension of 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) is provided with at least one interference layer (17). 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 chosen such that the thin-film interference filter (15) in the event of illumination at least one particular angle of observation and/or angle of illumination generates, by means of interference, a color which differs from at least one color which is generated in the event of illumination at this angle of observation and/or angle of illumination in at least one of the other zones (42 to 47) of the first color region.
