is shown in fig9 and 10 from the front and in cross section fig1 shows the cross section of such an antifalsification paper in which one side is provided with additional paper layer 9 this gives the antifalsification paper a homogeneous appearance on one side on this side it can thus be printed all over like conventional antifalsification papers on the other side the antifalsification paper is interrupted by safeguarding band 19 if the safeguarding band has holographic or other optically variable effects it seems useful to include these areas in the printed image only in the transitional area if the safeguarding band only has structures with metallic luster which would each be relatively easy to imitate per se it is recommendable to provide the security print steel intaglio printing guilloche pattern etc over this area as well this combines or firmly connects the metallic luster of the safeguarding band with the security print in the embodiments shown in fig1 and 13 antifalsification paper 23 is connected on each side with further paper layer 27 28 outer paper layers 27 28 have windows 16 in the area of the safeguarding band that are disposed relative to each other such that the safeguarding band is accessible on both sides in one case through one window only from the front in another case and finally.
