Abstract
The invention relates to a security paper having a security thread embedded therein, running from edge to edge, that is printed with luminescent colors in such a way that they are invisible in normal lighting. The luminescent colors are provided along the security thread in successive overlapping portions which, when the colors are excited, have a length recognizable to the naked eye and show characteristic mixed fluorescences in the overlapping areas.
