Abstract (en)

[origin: WO2019068362A1] The invention relates to an optically variable see-through security element for safeguarding valuable objects, having a planar, optically variable surface pattern, which exhibits a different color in a view through it compared with a plan view and has almost no color shift effect in a view through it, wherein the optically variable surface pattern contains a multiplicity of facets which have an effect substantially in terms of geometric optics and the orientation of which is characterized in each case by an angle α of inclination relative to the plane of the surface pattern which is in a range of 0° to 30°, wherein the facets are provided with a semitransparent functional layer, which appears in a different color in a view through it compared with a plan view and has almost no color shift effect in a view through it, and the optically variable surface pattern contains at least two partial regions each having a multiplicity of similarly oriented facets, wherein the facets of one partial region have a small angle α of inclination and the facets of the further partial region have a high angle α of inclination, such that the optically variable surface pattern, in a view through it, appears with a high color variegation or chroma in the partial region in which the facets have a small angle α of inclination, and appears with a low color variegation or chroma in the partial region in which the facets have a high angle α of inclination.
