  • Patent number: 7773162
    Abstract: There is described a signing film wherein provided on a background of the signing film is a decorative printing which forms a security feature and which fluoresces when viewed under UV light. So that the decorative printing which fluoresces under UV light is not to be perceived when viewing the surface of the signing film at different viewing angles in ambient light, it is proposed that the background of the signing film has at least two background layers and between them the decorative printing comprising a lacquer which contains a high-viscosity binding agent and is mixed with pigments which fluoresce under UV light, so that after the printing operation and the drying operation it is of a small layer thickness as a consequence of the high viscosity.
