Abstract
A security element and a value document having such a security element in the form of a strip having a first and second polymer layer are shown, having a visually recognizable halftone printed image, which is luminescent under UV radiation, between the first and second layer, wherein the halftone printed image has an opacity and forms at least one imprint area having a boundary contour within the security element. To increase the forgery protection, it is proposed that at least one of the two polymer layers have an opacity at least in the region of the boundary contour of the imprint area and be adapted in its opacity to the opacity of the imprint area, in order to diminish the visual recognizability of the boundary contour of the imprint area of the luminescent halftone printed image on the security element.
