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.
