Security element comprising a support

Abstract

The security element production process involves applying an effect layer (34) to a plastic support film (32), and an auxiliary transfer layer (36) to the entire surface of both. The adhesion of the auxiliary transfer layer to the support film is less than that to the effect layer. An adhesive layer (38) is then applied to the target substrate (35) to transfer the formed layer compound.

Description

technical field [0001] The invention relates to a security element which can be used to protect security paper, important documents and similar documents having such a transparent or translucent substrate. The invention further relates to a security arrangement comprising such a security element and a security document provided with said security element. Background technique [0002] For polymer-based banknotes, see-through windows have been present on banknotes for some time. However, the see-through window alone does not provide any additional security to the banknote against counterfeiting. It has been suggested, however, that the see-through window, with its different security features, can also be applied to banknotes to a certain extent. [0003] For example, in the publication WO 98 / 15418 A1 a banknote capable of self-testing is described, which is a relatively flexible paper with identifiers provided on a plastic substrate. The self-checking banknote is provided ...

Problems solved by technology

[0005] However, complex auxiliary means are not always effective, and authenticity checks related to this are relatively time-consuming

At this time, even if the calibration only takes a few seconds, the user will feel time-consuming and troublesome

Thus, in many cases, the authenticity check is completely omitted, so that the security feature has no protective effect
