摘要:
A security document having in order a) a first laser markable layer, present as a self-supporting layer or as a layer on a support; b) at least one polymeric overlay; and c) a second laser markable layer; wherein the second laser markable layer exhibits a higher laser sensitivity than a non-laser marked area of the first laser markable layer but produces a smaller maximum optical density or a smaller gloss on laser marking. Methods for manufacturing the security document are also disclosed.
