Security element as well as value document having such a security element

1. A security element for a security paper or value document comprising:

a carrier comprising a motif region which provides a visually perceptible motif having a first and a second motif part,

wherein the motif region comprises a first micro-optic representation arrangement which presents at least two different images in viewing angle-dependent fashion as a first motif part, and a second micro-optic representation arrangement which presents a reflective surface as the second motif part, said reflective surface imitating a bulge relative to the actual macroscopic spatial form of the second micro-optic representation arrangement,

wherein the second micro-optic representation arrangement has embossed microscopic structures which are furnished with a reflection enhancing coating, and

wherein the first micro-optic representation arrangement comprises microstructures and micro-imaging elements to image the microstructures in magnified form, the microstructures being provided both in a region of the first motif part and in a region of the second motif part.

2. The security element according to claim 1 , wherein the two motif parts are arranged to be contiguous.

3. The security element according to claim 1 , wherein one of the two motif parts at least partly surrounds the other of the two motif parts.

4. The security element according to claim 1 , wherein the two motif parts either or both at least partly overlap and are at least in certain regions nested into each other.

5. The security element according to claim 1 , wherein the first micro-optic representation arrangement presents the at least two different images such that the images at least in certain regions either or both overlap and are nested into each other.

6. The security element according to claim 1 , wherein the first micro-optic representation arrangement presents different views of the same object as the at least two different images.

7. The security element according to claim 1 , wherein the first micro-optic representation arrangement presents the at least two different images such that for a viewer there results a stereographic representation of an object with absolute depth information.

8. The security element according to claim 1 , wherein the first micro-optic representation arrangement is configured as a hologram.

9. The security element according to claim 1 , wherein the first micro-optic representation arrangement produces an orthoparallactic representation.

10. The security element according to claim 1 , wherein the second micro-optic representation arrangement presents the reflective surface in a reliefed impression.

11. The security element according to claim 1 , wherein the second micro-optic representation arrangement has a multiplicity of reflective facets that have different orientations with respect to each other.

12. The security element according to claim 1 , wherein the second micro-optic representation arrangement has a reflective Fresnel structure with varying grating period.

13. The security element according to claim 1 , wherein the second micro-optic representation arrangement has asymmetric diffraction structures or matt-structure grating images.

14. The security element according to claim 1 , wherein the micro-imaging elements of the first micro-optic representation arrangement and the microscopic structures of the second micro-optic representation arrangement are embossed in a same embossing lacquer layer.

15. The security element according to claim 1 , wherein the security element is configured as a multilayer layered composite.

16. A value document comprising the security element as recited in claim 1 .
