Accordingly, from the viewing direction 42, the partial areas inscribed with this direction can be recognized by the markings 26 and, for a viewer, are combined to form the letters "BBB". From the shallower viewing directions 44, 46, the cylindrical lenses each show only portions of the optically variable recording layer 30 which have not been modified by laser radiation and contain no markings.
- the security element 20 thus has an optically double-variable appearance when viewed.

- the numbers appear colorless in front of the color-shifting background of the thin-film element 50; in transmitted light they appear bright against the dark background of the reflection layer 52.
- the security element of FIG. 3 (b) is designed for viewing both in plan view and in transparency, and in particular can be arranged in a transparent or translucent window area or over an opening of a card 10 or another data carrier.
- two different tilt images can also be generated for viewing in a top view and a view, as illustrated in FIG. 3 (c).
- the thin-film element with low laser energy recesses 66 were produced only in the absorber layer 56 of the thin-film element 50, which respectively form first partial identifications 24-A and 26-A of the markings 24, 26.

- the partial indicia 24A, 26A formed by the recesses 66 may be complementary to the letters "AAA” from the viewing direction 40 and the letters “BBB” from the viewing direction 42, and those indicated by the continuous recesses 62 formed sub-labels 24-B, 26-B from the viewing direction 40 to the numbers "1 1 1” and from the viewing direction 42 to the numbers "222" supplement.
- the viewer When viewed from above, the viewer then sees the partial identifications 24A, 26A formed by the recesses 66 silvery with the color impression of the reflection layer 52 and the partial identifications 24B, 26B formed by the continuous recesses 62 colorless, ie decreases when tilting the security element, a tilting picture "AI AI AI" after "B2 B2 B2" before a color-shifting background true, the letters each appear silvery shiny and the numbers appear colorless.
- the recesses 66 which are present only in the absorber layer 56 can not be seen, while the recesses 62 through the recesses 62 Part markings 24-B, 26-B appear bright against the dark background of the reflective layer 52.
- the observer therefore perceives a tilted image of bright numbers "1 1 1" to "2 2 2" against a dark background.
- the reflection layer of the optically variable recording layer can not only be present over the full area outside the markings, as shown in FIGS. 2 and 3, but can also be screened there at least in partial areas.
- FIG. 4 shows a security element 70 with an optically variable recording layer in the form of a color-shifting thin-film element 72 with a rastered reflection layer 74, an absorber layer 56 and a dielectric spacer layer 54.
- the first and second markings 24, 26 are similar to the embodiment of FIG 3 (b), formed by recesses 76 both in the absorber layer 56 and in the reflection layer 72 of the thin-film element 70.
- the reflection layer 74 is scanned outside the markings 24, 26 and consists of a multiplicity of spaced raster elements 78.
- the security element 70 is therefore not opaque, but weak, even outside the markings transparent.
- the grid elements 78 may be circular in shape with a diameter between 10 ⁇ and 100 ⁇ .
- the rasterization can be carried out in such a way that the raster elements 78 are visible in a direction-dependent manner, but that averaged over several lens diameters, a direction-independent transmittance of the reflection layer 74 is present.
- a stochastic distribution has Development of the raster elements 78 has been found to be advantageous in order to avoid unwanted moiré effects.
- the security element can also be combined with further, for example printed, face / face features, such as print information disappearing in a transparent manner.
- the latter can also be provided on the back of the security element.
- the reflection layer of the optically variable recording layer can also be partly full-surface and partially screened.
- FIG. 5 shows a security element 80, which is largely constructed like the security element 70 of FIG. 4.
- the recording layer 72 of the security element 80 contains a reflection layer 82, which is present in its entirety in the first partial regions 84 and in the second partial regions 86 in the rasterized manner.
- the rasterized subregions 86 form a motif through their outline shape, which, due to the weak transparency of the rastered subregions 86, becomes visible in the light of the opaque background of the full-surface subregions 84.
- the security element 80 thus has, in addition to the optically doubly variable appearance, a supervisory
- this motif can also be formed with a plurality of gray levels.
- the markings 24, 26 can also be introduced into the recording layer in a different manner instead of the described laser application through the lenses 34, for example by demetallization of an absorber or reflection layer by a washing, etching, or Oil ablation. Also, optical ablation may be accomplished, for example, by patterning the recording layer over a high resolution mask with a single exposure.
- micro-hollow mirrors 92 may also be considered. Referring to FIG. 6, a security element 90 includes a grid of a plurality of micro-cavities 92 separated by a spacer layer 28 from the optically-variable recording layer 72.
- the recording layer 72 must be at least partially transparent in this variant of the invention, which can be ensured, for example, by the use of a screened reflection layer 74. Furthermore, the recording layer 72 is to be arranged such that its optically variable effect is visible from the underside 96, that is to say the side facing the hollow micro-mirrors 92, as shown in FIG.
- the optically variable effect is from the top side
- a motif can be inscribed in the optically variable recording layer 72 by means of laser exposure in the manner described above, or the recording layer 72 can be structured by a washing, etching, or oil ablation process.
- the reflector 94 of the micro-cavity mirror 92 can be designed as an optically variable layer and can be formed in particular by a color-shifting thin-film system.
- the reflector 94 of the micro-cavities 92 may also be partially or completely scanned to produce see-through effects.
- the screened areas of the reflector 94 can form a motif and / or make additional security features attached to the back of the security element 90 visible.
- the tilt images of the recording layer may exhibit an enlargement and / or depth effect, as known from Moire Magnifier systems.
- Moire Magnifier systems The generation and properties of such microoptical representational arrangements are described, for example, in international applications WO 2009/00528 A1 and WO 2006/087138 A1, the disclosure of which is incorporated into the present description to this extent.
