Abstract: A security inlay having optically recognizable characters for an identity document comprises a first transparent layer and a second transparent layer. A color coating is situated on the first transparent layer. Furthermore, a first UV color coating, which reflects at least UV light at least in a first wavelength range, is situated on the first layer and/or on the color coating. The first and second transparent layers are connected to one another. A first portion of the optically recognizable characters is formed by blackened sections in at least one of the layers. A second portion of the optically recognizable characters is formed by the color coating. A third portion of the optically recognizable characters is formed by the UV color coating. The first and the second portions of the optically recognizable characters reflect visible light. The third portion of the optically recognizable characters reflects UV light.

Abstract: A security inlay having optically recognizable characters for an identity document comprises a first transparent layer and a second transparent layer. The first and second transparent layers are connected to one another. A first portion of the optically recognizable characters is formed by blackened sections in at least one of the layers. A second portion of the optically recognizable characters is formed by the color coating. The first and second portions are arranged and configured to reflect visible light. Infrared light is reflected by the first portion of the optical characters. During irradiation with visible light, the security inlay thus shows first graphical information formed jointly by the first portion of the optically recognizable characters and the second portion of the optically recognizable characters. Under irradiation with infrared light, the security inlay shows second graphical information formed by the first portion of the optical characters.

Abstract: A polymer composite device comprises a first thermoplastic covering layer of a polymer material with a first softening temperature and a second thermoplastic covering layer of a polymer material with a second softening temperature. The polymer composite device also comprises a carrier layer, which is arranged between the first covering layer and the second covering layer. An inner layer, which comprises at least a first thermoplastic inner layer ply of a polymer material with a third softening temperature, is arranged between the first covering layer and the second covering layer. The inner layer at least partially surrounds the carrier layer in a material-bonding manner. The third softening temperature is lower than the first softening temperature and lower than the second softening temperature.
