Abstract (en)
[origin: EP2439074A2] The paper has watermarks (14) forming a pattern e.g. portrait, and overlapped by an opening region (16). The opening region forms another pattern and is formed from a linear opening in the paper so that overlapping of the watermarks and the opening region forms a combination pattern (12) of the patterns. The linear opening is produced by effect of laser radiation. The combination pattern has a visual impression changing in transmitted light relative to reflected light. The watermarks include a thin place with a paper thickness reduced relative to surrounding. An independent claim is also included for a method for producing a security paper.
