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.
