Abstract (en)

The valuable document such as bank note, certificate, share or identification document, comprises a flat paper substrate (2), which has a dirt-repellent coating (3, 3') at each of its both major surfaces, where the coating has a composition, which contains silicone resin and/or fluorine silicone resin and polytetrafluoroethylene solid particles. The coating is uppermost cover layer of the valuable document. The valuable document is printed under the coating and/or has a coating, which is free from silicone resin and/or fluorine silicone resin. The valuable document such as bank note, certificate, share or identification document, comprises a flat paper substrate (2), which has a dirt-repellent coating (3, 3') at each of its both major surfaces, where the coating has a composition, which contains silicone resin and/or fluorine silicone resin and polytetrafluoroethylene solid particles. The coating is uppermost cover layer of the valuable document. The valuable document is printed under the coating and/or has a coating, which is free from silicone resin and/or fluorine silicone resin. The coating is present on an outer- and an inner sublayer, where both sublayers contain silicone resin and/or fluorine silicone resin. The inner sublayer is free from polytetrafluoroethylene solid particles. The average diameter of polytetrafluoroethylene solid particles is 30-200 nm. The proportion of polytetrafluoroethylene solid particles is 1-20 wt.%. The coating has a physically drying silicone resin and/or fluorine silicone resin or silicone resin crosslinked over silicon-oxygen bonds and/or fluorine silicone resin. An independent claim is included for a method for producing a valuable document.
