摘要：
The invention relates to a method of generating a laser marking in a security document by means of at least one laser beam, the security document having at least one laser-markable layer and also at least one reflecting layer which overlaps at least partly with the at least one laser-markable layer and has opaque regions. The at least one reflecting layer has at least one transparent region and, at least visually, is not significantly altered by the laser treatment of the laser-markable layer.
