Definitions
- the invention relates to a film containing i) a Po ly carbonate or copoly carbonate of the formula (1-1), (1-2), (1-3) or (1-4), ii) 0.1 to 5 wt. -% of a first additive; iii) optionally 0.1 to 15% by weight of a second additive that is different from the first additive, the first additive ii) containing or being an antistatic compound, as well as the use of the film according to the invention in a security document and the use of component i) for the production of a laser-engravable foil.
- the invention also relates to a layer structure comprising the film according to the invention.
- security documents for the area of security documents, in particular identification documents, the embedding of several security features is absolutely necessary, in particular to ensure the originality of these security documents.
- security documents in particular identification documents, increasingly include polycarbonate.
- Documents based on polycarbonate are particularly durable and have a high level of security against forgery.
- Popular security features are transparent areas in, for example, identification cards or in the data pages of passports. These transparent areas are also called “windows". Holograms, security prints and other elements can be introduced into these windows, which can be recognized as originals or falsifications by looking at them.
- the function of the security feature is based on the high transparency of polycarbonate. If the transparency of the document in the window is impaired, then it could be a forgery.
- a problem in the production of the security documents can be the deformation of the film during production, but also the inclusion of air bubbles. Waves often arise in the individual layers, which on the one hand are unsightly, but on the other hand can also lead to the data in the security element not always being correctly recognizable or readable.
- this invention is concerned with reducing at least one of these problems.
- Another object of the invention is to provide smooth films for use in security documents.
- materials for use in security documents which enable the security documents formed therefrom to be deformed to a small extent.
