Description

The invention relates to a security element for securities or security papers, the security element having a first structural area with first structures which generate a first movement image when the security element is tilted about a first axis.

Security elements of the type mentioned are usually used to increase the security against forgery of securities or security papers, such as bank notes, ID cards, credit cards, ATM cards, tickets, etc.

The object of the present invention is to create a security element with increased security against forgery.

According to the invention, this object is achieved by a security element of the type mentioned at the outset in that the security element additionally has at least one second structural area with second structures which generate a second movement image when the security element is tilted about a second axis.

Furthermore, it can be expedient if the first structure area and the second structure area are arranged directly adjacent to one another or the first structure area and the second structure area are arranged at a distance from one another.

Furthermore, it can be provided that an impression of movement of the first movement image when tilting about the first axis in relation to the direction of movement is different from an impression of movement of the second movement image.

In addition, it can be provided that the impression of movement of the second movement image when tilting about the second axis with respect to a direction of movement is different from the impression of movement of the first movement image.

An embodiment is also advantageous according to which it can be provided that the second movement image does not generate any movement impression when tilted about the first axis, or that the first movement image does not produce any impression of movement when tilted about the second axis.

According to a development, it is possible that the first and the second axis enclose an apex angle between 10 ° and 90 °, preferably enclose an apex angle between 45 ° and 90 °.

Furthermore, it can be expedient if a continuous design runs over the first structural area and the at least second structural area without tilting and / or in a horizontal position and / or at a specific viewing angle.

• regardless of the direction of movement of the tilting about a first or second axis, a movement of the first and / or second movement image in the transverse direction to the movement axis is perceived.

Furthermore, it can be provided that the possible impressions of movement, as well as the possibility that no impression of movement arises, can be combined with one another as desired.

According to a particular embodiment, it is possible for the structure regions to be formed by micromirrors and / or by diffractive structures.

According to an advantageous development, it can be provided that the security element is used for documents of value and / or polymer banknotes and / or card applications.
