<p>The invention relates to a spreadable paint containing a pigment mixture, an adhesive as well as water and known coating aids, wherein the pigment mixture is composed of precipitated silicic acid with a specific surface area of 600 m2/g to 700 m2/g and an absorber pigment which absorbs excitation radiation from the ultraviolet or visible region of the spectrum; and relates further to a coated paper (1) coated with a coat made from one of these spreadable paints, whose paper carrier (2) contains a paper dye which emits fluorescence as a result of being irradiated with an excitation radiation, which itself is at least partially absorbed by an absorber pigment of the coating. The coating (3) according to the invention preferably absorbs UV light and has the characteristic that large areas detach from the paper carrier (2) due to mechanical tampering attempts such as scratching or erasure so that forged forms are rendered recognizable with the help of, for example, optical whiteners in the paper carrier (2).</p> |
