Abstract (en)

[origin: WO2021028075A1] The invention relates to an optically variable security element (12) for securing valuable items, the surface extent of which defines a z-axis perpendicular thereto, comprising a multicolour reflective surface area (20), wherein: the multicolour reflective surface area (20) contains two relief structures (24, 34) which are arranged in the z-direction in different vertical levels and form a relief structure lying lower and a relief structure lying higher; the relief structure (24) lying lower is provided with a first colour coating (26) following the relief shape, and the relief structure (34) lying higher is provided with a second colour coating (36) following the relief shape; a light-permeable coloured planar structure (44) is arranged in the z-direction at a vertical level between the two relief structures (24, 34); the two relief structures (24, 34) and the planar structure (44) overlap in an overlapping region; and the second colour coating (36) of the relief structure (34) lying higher comprises at least one recess (54) in the overlapping region, in which recess, when viewing the security element, the relief structure (24) lying lower appears owing to the combined colour effect of the coloured planar structure (4) and the first colour coating (26).
