Abstract

The present invention relates to an optically variable security element (12) for security papers, value documents and other data carriers, having a substantially transparent substrate (20) having opposing first and second main surfaces (22, 24), an arrangement composed of microlenses (26) arranged on the first main surface (22) of the substrate, arranged on the second main surface (24) of the substrate, a laser- sensitive recording layer (30) that includes stacked first and second sub-layers (32, 34), the first sub-layer (32) being arranged between the substrate (20) and the second sub-layer (34), a plurality of microholes (40) produced in the laser-sensitive recording layer by the action of laser radiation, of which each microhole (40) is associated with a microlens (26) and is visible when the security element is viewed through the associated microlens (26) from a certain viewing angle, the plurality of microholes comprising a plurality of first and a plurality of second microholes (42, 44), the first microholes (42) being present in the first sub-layer (32) and not going through the recording layer (30), and the second microholes (44) going through the recording layer (30) with the first and second sub-layer (32, 34), and the diameter of the first microholes (42) being larger than the diameter of the second microholes (44).
