Security paper (I), for the production of documents of value such as bank notes, passports and identity papers, comprises a flat substrate (A) at least partially covered with a dirt-repellent protective layer (B) to increase its life whereby the protective layer (B) comprises at least two lacquer layers (B1 and B2) such that the lower layer (B1) is applied to the substrate (A) as a physically drying lacquer layer that is in contact with the substrate (A) and closes its pores and the upper layer (B2) protects the substrate (A) from physical and chemical effects. Independent claims are included for: (1) documents of value produced from the paper (I) and; (2) a process for the production of the paper (I) by preparation of a flat substrate (A), application of a lacquer layer (B1) and layer (B2). |
