Problems solved by technology
Typically, adhesive layers are used on both sides of the TPE material, which leads to the above-mentioned risk of delamination
There is an increased risk of forgery and / or tampering here, since the inlay may be removed without destruction and integrated into another layer composite (forgery)
In addition, the data carried or included in the inlay can be falsified
[0006] An inlay of TPE material protects the integrated component reliably against mechanical damage, but, in addition to the above-mentioned problems, it has disadvantages for processing, especially for separation of inlay stacks, since such inlays tend to be damaged by Clogging due to materials used
This blocking tendency is also problematic for precise alignment of the inlay when placing the inlay and additional membranes together to obtain the final membrane composite

[0009] specific implementation plan
[0010] In order to achieve this technical problem, the present invention teaches an inlay for security and / or value documents, the inlay comprising a core layer comprising electronic components and / or diffractive security elements, and the core layer consisting of a second a base polymer formation; comprising two inlay cover layers disposed on both sides of the core layer, the inlay cover layers being formed from a second base polymer different from the first base polymer, wherein the core The layer and the inlay cover are bonded to each other by a latent reactive adhesive.
[0011] Latently reactive adhesives are known per se in many different ways. In this context, reference can be made, for example, to document EP0922720, the disclosure of which is hereby incorporated by reference. Typically, these are, for example, polyisocyanate particles in dispersion, which are surface-deactivated. Such dispersions may contain polyisocyanate-reac...

Abstract
The invention relates to an inlay (1) for a security and / or value document (2), comprising a core layer (3) which contains electronic components (4) and / or diffractive security elements and is produced from a first base polymer, comprising two inlay cover layers (4, 5) which are disposed on either side of the core layer (3) and produced from a second base polymer that is different from the first base polymer, wherein the core layer (3) and the inlay cover layers (4, 5) are connected to each other by way of a latent-reactive adhesive (6, 7).
Description
technical field [0001] The invention relates to an inlay for security and / or value documents, the inlay comprising a core layer comprising electronic components and / or diffractive security elements, for example a three-dimensional hologram (Volumenhologramme), and the core layer is formed from a first base polymer. The invention furthermore relates to a method for producing such an inlay and the use of such an inlay for producing security and / or value documents. Background technique [0002] Security and / or value documents such as identity cards, passports, ID cards, access control cards (Zugangskontrollausweise), visas, tickets, driver's licenses, driving books, personalized securities, credit cards, or personalized chip cards are increasingly Many contain electronic circuits and other active and passive electronic components, such as integrated semiconductors (ICs), as well as chip modules, displays, batteries, coils, capacitors, contacts (Kontaktstelle), etc. [0003] W...
