The invention relates to a security document (2), which comprises a carrier layer (14), on which a laser-sensitive layer (12) is arranged. At least personalization data (4, 8) of an owner of the security document (2) are written into the laser-sensitive layer (12) by means of a laser. In order to protect against unauthorized changing of the data (4, 8) written into the laser-sensitive layer (12) and in order to protect against mechanical wear, e.g., scratching, the laser-sensitive layer (12) has geometric structures (6), such as letters, symbols, and characters, in the surface of the laser-sensitive layer accessible from outside. For better protection, a transparent layer (10) can additionally be arranged on the laser-sensitive layer (12), wherein the geometric structures (6) are then arranged in a surface of the transparent layer (10) accessible from outside. |
