Abstract (en)
[origin: WO2019063560A1] The present invention relates in particular to a high-durability paper support for printing a security document, in particular a banknote, comprising cellulose fibres, in a proportion of at least 50% by weight relative to the total weight of the paper support in the dry state, additives and adjuvants, at least one binder, and which further comprises at least one olephobic and hydrophobic agent based on an organic compound containing perfluoropolyethers (PFPE), in a concentration of greater than 0% and less than or equal to 5% by weight in the dry state relative to the total weight of the paper support in the dry state, characterized in that it furthermore comprises at least one non-fibrous structural reinforcing agent from the family of softening agents, i.e. agents that increase the flexibility of the cellulose fibres, in an amount of between 0.5% and 15% by weight relative to the total weight of the paper support in the dry state.
