识别文件具有个性化的视觉标识符及其生产方法

Identification document having a personalized visual identifier and method for production thereof
Abstract:
An identification document (10) comprises a personalized first visual marking (14) that is arranged in a first region (12) of the identification document (10), the first region (12) being configured in such a way that, upon laser irradiation of the same, local darkenings of the optical impression of the identification document (10) are produced, resulting from material transformations. The identification document (10) further exhibits a second visual marking (26) that produces the optical impression of a copy of the first visual marking (14) and is arranged in a second region (22) of the identification document (10), the second region (22) being configured in such a way that, upon laser irradiation of the same, local lightenings of the optical impression of the identification document (10) are produced, resulting from material transformations.
Abstract(Chinese):

识别文件（10）包括设置在识别文件（10）的第一区域（12）中的个性化第一视觉标记（14），所述第一区域（12）被配置成在激光照射时 由于材料转换，产生了识别文件（10）的光学印象的局部变暗。 识别文件（10）还具有产生第一视觉标记（14）的副本的光学印象的第二视觉标记（26），并被布置在识别文档（10）的第二区域（22）中， 第二区域（22）以这样的方式配置，使得在激光照射时，由材料变换产生识别文档（10）的光学印象的局部减轻。
