Security deposit for a document of identification and method for producing a security deposit for a document of identification

摘要

A security insert with optically identifiable signs for a passport document comprises a first transparent layer and a second transparent layer. On the first transparent layer is a paint application. The paint application is transparent to infrared light. The first transparent layer and the second transparent layer are connected to each other. At least one of the transparent layers has blackening. A first part of the optically recognizable characters is formed by the blackening in at least one of the layers. A second part of the optically recognizable characters is formed by the paint. The first and second parts of the optically recognizable characters are arranged and adapted to reflect visible light. Infrared light is reflected by the first part of the optical sign. The security insert thus shows, during the irradiation with visible light, a first graphic information which is formed jointly by the first part of the optically recognizable characters and the second part of the optically recognizable characters. Under irradiation with infrared light, the security pad shows second graphical information formed by the first part of the optical characters.
