Abstract (en)
[origin: WO2022233449A1] The invention relates to a method for producing a security element, to a security element, and to a security document. The method comprises the following steps: providing a substrate (12) embodied with a planar extent and having a front and a rear side (14, 15) and at least one portion (16); b1) applying a stabilizing coating (17) in the portion (16) on the rear side (15) of the substrate (12); b2) applying an adhesion promoter coating (18) in the portion (16) on the front side (14) of the substrate (12); and c) applying a transfer element (19) on the adhesion promoter coating (18). As seen in a plan view of the planar substrate (12), the transfer element (19) is arranged in a manner bounded by an edge (22) lying within the portion (16) on at least a first and a second side (20, 21), and the stabilizing coating (17) and the adhesion promoter coating (18) are each formed on at least one of the first and second sides (20, 21) of the transfer element (19) in a manner extending beyond the edge (22) thereof. The stabilizing coating (17) and the adhesion promoter coating (18) each comprise a, more particularly optical or machine-readable, e.g. luminescent, feature component, the stabilizing coating (17) and the adhesion promoter coating (18) jointly forming a security feature of the security element.
