By way of introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference symbols or the same component names, whereby the disclosures contained in the entire description can be transferred accordingly to the same parts with the same reference symbols or the same component names. The position details chosen in the description, such as above, below, to the side, etc., also relate to the figure immediately described and shown and these position details are to be transferred accordingly to the new position in the event of a change in position.

It is also pointed out that the figures are described comprehensively.

According to FIG. 1, a security feature 1 according to the invention for a value document 2 has a first partial image 3 and a second partial image 4. The first partial image 3 is arranged in a first partial area 5 and the second partial image 4 is arranged in a second partial area 6 different from the first partial area 5. By folding the first sub-area 5 or the second sub-area 6 by 180 ° around an imaginary or marked fold line 7 lying between the two sub-areas 5, 6, the two partial images 3, 4 become an overall image 8 formed by the sum of the two partial images 3, 4 composed. By folding the two sub-areas 5, 6 by 180 ° around the fold line 7, the sub-areas 5 and 6 and / or the

Parts 3 and 4 come to lie on top of each other.

As will be explained in more detail below, there are different options for forming the two partial images 3 and 4. For example, the first partial image 3 can be designed as a positive image or text element, while the second partial image 4 can be designed as a corresponding negative image or text element that is mirrored to the first partial image 3. If the security 2 is folded up and the two partial images 3 and 4 are superimposed, the two partial images complement each other to form a closed surface. If for making

described in connection with FIGS. 3 and 4.

Alternatively, the two partial images 3 and 4 can also complement one another in the manner shown in FIGS. 1 and 2 to form the overall image 8. In the embodiment shown in Figs. 1 and 2, the two partial images 3 and 4 z. B. each represent one half of the overall image 8. Thus, the partial image 3 could, for example, represent a half portrait of a person / or an animal, etc. Alternatively, the two partial images 3 and 4 can also be used to provide third information in the form of the overall image.

of the 8 supplement.

According to FIG. 3, the first partial image 3 and the second partial image 4 can be formed from image elements 9, 10, 11, 12, 13, 14, in particular lines, points or areas. The picture elements 9, 10, 11 of the first partial image 3 and / or the picture elements 12, 13, 14 of the second partial image 4 can each form a contiguous area, as is shown in FIG. 2, for example. Furthermore, the first partial image 3 and / or the second partial image 4 can each have locations covered by the image elements 9, 10, 11, 12, 13, 14 and / or locations 15 uncovered by the image elements 9, 10, 11, 12, 13, 14 , 16, 17, 18, 19, 20 include.

As shown in FIG. 3, some or all of the picture elements 9, 10, 11 of the first partial image 3 in the first partial area 5 can only be present at locations which correspond to locations 15, 16, 17 which are in the second partial area 6 of Image elements 12, 13, 14 of the second partial image 4 are uncovered. According to an embodiment variant, all or only some of the image elements 12, 13, 14

of the second partial image 4 can also be arranged in places which are the places of the first

th partial image 3, which are uncovered by picture elements 9, 10, 11.

After folding the first sub-area 5 or the second sub-area 6 by 180 °, locations with image elements 9, 10, 11 of the first sub-area 5 towards locations 15, 16, 17 of the second sub-area 6 that are uncovered by image elements 12, 13, 14

As shown in FIG. 4, the second partial image 4 can correspond to a mirror image of the first partial image 3 around the fold line 7. This can lead to that already mentioned above, to an overall image 8 that is closed over the entire area. As an alternative, the two partial images 3 and 4 can also overlap one another in such a way that, through partial or complete superimposition of the two partial images 3 and 4, the resulting overall image 8 contains previously unrecognizable information in the form of a character,

Pattern etc. represents.

The picture elements 9, 10, 11 of the first partial image 3 and / or the picture elements 12, 13, 14 of the second partial image 4 can be made of a metal and / or a metal alloy and / or a printing ink and / or an optically variable effect, in particular a Color shift effect, generating material or layer structure

The two partial images 3, 4 of the security feature can be applied on the same side of the carrier film 23, or else on different sides of the carrier film 23, as shown in FIG. 3 with dashed lines. According to the variant with the picture elements shown in broken lines in FIG. 3, the broken-line picture elements of the first partial image 3 are arranged below the carrier film 23, while the picture elements 12, 13, 14 of the second partial image 4 are located above the carrier film 23. Thus, according to this embodiment, the carrier film 23 lies between

between the first partial image 3 and the second partial image 4.

As a material for the carrier film 23, it has been found to be particularly advantageous if this is selected from one or more materials from the group polyimide (P1), polypropylene (PP), monoaxially oriented polypropylene (MOPP), biaxially oriented polypropylene (BOPP), polyethylene (PE), polyphenylene sulfide (PPS), polyetheretherketone (PEEK), polyetherketone (PEK), polyethyleneimide (PEI), polysulfone (PSU), polyaryletherketone (PAEK), polyethylene naphthalate (PEN), liquid crystalline polymers (LCP), polyester, polybutylene terephthalate (PBT) , Polyethylene terephthalate (PET), polyamide (PA), polycarbonate (PC), cycloolefin copolymers (COC), polyoxymethylene (POM), acrylonitrile butadiene styrene (ABS), polyvinyl chloride (PVC) ethylene tetrafluoroethylene (ETFE), polytetrafluoroethylene (PTFE), polyvinyl fluoride (PVF), polyvinylidene fluoride (PVDF) and / or ethylene-tetrafluoroethylene-hexafluoropropylene fluoroterpolymer (EFEP).

Furthermore, the carrier film 23 can have a thickness between 5 - 700 μm, preferably 5 -

200 μm, particularly preferably 5-125 μm, in particular 10-75 μm.

Security element 22 can, for example, be a security thread, a security

strip or a patch is.

Furthermore, the value document 2 can have a first and a second security element, the security feature being applied to both security elements. Here, the first partial image 3 can be arranged on the first security element and the second partial image 4 on the second security element. The sub-areas 5 and 6 are assigned to different security elements in this case. The two security elements are preferably different security elements. For example, the first security element can be in the form of a strip and the second security element in the form of a patch or the first security element as a thread and the second as a strip. Of course, any other combinations of configurations of the safety

elements possible.

According to a particularly favorable variant of the invention, the security element 23 is arranged in the region of a window of the document of value 2. Here, both sub-areas 5 and 6 or only a part of the two sub-areas 5 and 6 can be arranged in the area of the window, so that if the two sub-areas 5 and 6 and / or the two sub-images 5 and 6 overlap, the result is

animal overall image 8 can be seen in transmitted light and / or reflected light.

For the sake of clarity, it should finally be pointed out that, for a better understanding of the structure, some elements are not to scale and / or enlarged

and / or shown reduced.
