Abstract
A substrate for producing papers of value or security papers is described. The substrate may include a carrier layer, at least one security element applied at least one of onto and into the carrier layer, and a primer. The primer may be applied onto at least one of a first substrate side and a second substrate side of the substrate. The primer may be arranged, at least in some sections, between the carrier layer and the at least one security element. Additionally and/or alternatively, the primer may cover the at least one security element and/or the carrier layer such that regions of the at least one security element covered by the primer are not as well visible as regions of the at least one security element and/or the carrier layer not covered by the primer. The at least one security element may include a partial, reflective layer forming an image.
