Problems solved by technology

However, these Braille markings are likewise unsuitable as general security elements, since they can only be read and recognized correctly by specially trained users
In addition, the effects of circulating circulation can lead to a significant reduction in tactility

Embodiment Construction

[0043] no matter press figure 1 The security documents according to FIG. 4 each have a substrate 1, which consists of a possibly suitably refined paper. The difference between the two security documents lies primarily in the different types of security elements employed in the two security documents.

[0044] exist figure 1 In the security document, the surface area of ​​a special film strip 2 is formed near the left edge area, such as figure 2 with 3 As shown in the sectional view of , it is fixed on the corresponding surface 4 of the substrate 1 by means of an adhesive 3 .

[0045] The film strip 2 forms a surface area of ​​the security document which differs in its surface properties from the properties of the corresponding surface 4 of the security document. In this example, the film strip 2 adopts a kind of embossing or other structure 6 that causes corresponding roughness on its surface 5 facing away from the substrate, for example it is as in figure 1 It may have ...

Abstract

There is proposed a security document comprising a security element, wherein the security element is of such a configuration that it can be determined by means of the sense of human touch. For that purpose either the surface nature of various surface regions can be selected differently so that the configuration and size of the different surface regions can be determined by the human sense of touch. Another possibility is for the substrate of the security document to be provided with suitably shaped openings which can be identified by means of the human sense of touch. A combination of different tactile security elements of that kind is also described.

Description

technical field [0001] The invention relates to a security document, in particular a security document, having at least one security element arranged on one surface of a substrate constituting the security document and / or at least one window forming at least part of a security element in the substrate shaped through hole. Background technique [0002] Securities, especially banknotes, check proofs, share certificates, etc., are increasingly provided with security elements which should be difficult to counterfeit and whose authenticity should also be able to be verified by a layperson without too much difficulty. Correspondingly, this also applies to other security documents such as ID cards, visas, etc. In this context, markings with optical changes or optical effects, for example structures with diffractive optical effects, eg holograms, partially reflective surface regions, etc., are increasingly used as security elements. It is also known to increase the security of doc...
