Abstract (en)
[origin: WO2021063542A1] The invention relates to a method for producing a security paper, comprising the following steps: providing a substrate (2) which extends planarly and has a front face (11) and a rear face (15); applying a transfer element (6; 8) to the front face (11), which transfer element is delimited by at least one edge; and applying a stabilization coating (7; 10) to the rear face (15) in a portion of the substrate that covers the transfer element (6; 8) in top view, the stabilization coating (7; 10) being applied in such a way that the portion has at least two surface sections to which different coating materials are applied and which differ with regard to the appearance of the stabilization coating (7; 10) that can be perceived or measured from the rear face (15).
