- the reagents used to react with solvents in general are composed for example of solid particles dispersed in the fibrous mass of the security paper and / or in the surfacing layers, particles which have the particularity of being insoluble in water and soluble in certain solvents likely to be used by falsifiers, the passage in solution of these particles in the liquid causing a coloration of the latter sufficiently large to be easily detectable with the naked eye, under visible or ultraviolet light.
- the face of the security papers comprising the variable indications is sometimes covered with a glued transparent protective film preventing access to the said indications, applied by cold pressure or by heat-sealing.
- the falsifiers are then led to try to peel off this film and then falsify the variable information using solvents, in particular non-polar solvents.
- the security paper is coated with glue and then affixed respectively to the page of a passport reserved for the visa or to any other medium to be traced.
- the falsifiers are then led to try to take off with solvents, in particular non-polar solvents, these visas or labels to use them for another purpose.
- apolar solvents used are for example chosen from the following list: White spirit, essence A, petroleum, turpentine essence, universal synthetic diluent, Scarlet water®, Zipo® essence, trichlorethylene, heptane, hexane, Un Du®.

- the zone reacting to non-polar solvents is separated by the barrier from the first outer face of the paper.
- the zone reacting to non-polar solvents is sufficiently isolated from the first external face to allow the presence in contact with the latter of an adhesive capable of containing non-polar products or traces of non-polar residual products.
- zone reacting to non-polar solvents means the part of the security paper containing the reagents capable of dissolving in the non-polar solvents, this part consisting for example of the fibrous mass and / or of a layer on the surface of the second outer face.
- the new security paper according to the invention thus makes it possible to offer protection against non-polar solvents used by falsifiers in their attempts at falsification.
- the reagents for non-polar solvents are preferably introduced into a surface layer in the vicinity of the second outer face of the paper, opposite to the first, rather than in the fibrous mass, that is to say that the zone reacting to the non-polar solvents is preferably closer to the second outer face of the paper than to the first outer face of the paper.
- the other chemical reagents which may be present in the security paper, in the fibrous mass and / or in a surfacing layer are the following: Reagents with bases, in particular with ammonia or with sodium hydroxide, reagents with acids, in particular with hydrochloric acid, reactants with oxidants, in particular with sodium hypochlorite or with hydrogen peroxide, reagents with polar solvents, in particular with ethyl alcohol, denatured or not, these reagents can be found independently in the fibrous mass or in the surface layers (barrier or not) of the paper depending on the reagents.
- one of the faces of the security paper has a mark visible to the naked eye, making it possible to distinguish it from the other face, for example a watermark.
- the barrier is located substantially in the vicinity of the first outer face, which in particular makes it possible to deposit the material or materials impermeable to nonpolar solvents constituting this barrier during the surface treatment of the fibrous mass of the security paper, by surfacing or online or offline sleeping.
- the surface treatment means used consist, for example, of a size press or a coater, in particular by gravure printing.
- barrier situated in the vicinity of the first external face it is meant that the barrier is closer to the first external face than to the second.
- the fibrous mass and the barrier or between the latter and the first outer face there may be one or more layers of surfacing and / or print writing.
- PNA polyvinyl alcohol
- the PNA used can possibly be carboxylated.
- polymers can also be used in particular in the form of a stabilized dispersion (synthetic latex), in particular polymers based on acrylic, nitrile, polyvinyl acetate, styrene butadiene, polyvinyl chloride, or even still other materials, in particular a starch or a fluorinated resin, and mixtures thereof. It is thus possible to use, to reinforce the barrier effect against solvents, a mixture of a water-soluble binder, such as starch or PNA with said latex.
- synthetic latex synthetic latex
- the barrier may consist of a surfacing layer, as indicated above.
- the first outer face of the paper can be in contact with an adhesive, the security paper obtained then constituting for example a visa or a security label, to be stuck on one of the pages of a passport or on a support to be traced.
- the invention also relates to an assembly comprising a security paper as defined above and an adhesive structure bonded to the first outer face of said paper.
- an adhesive structure can be constituted by a transparent film coated with adhesive, as explained above.
- the adhesive structure may also be constituted by a visa paper or a label produced by means of a security paper according to the invention, that is to say comprising at least one zone reacting to non-polar solvents and a barrier impermeable to solvents. apolar, in the vicinity of which the adhesive is located. There may be layers of surfacing and / or writing print between the paper and the adhesive.
- this surfacing layer is formulated so that the adhesive force between the adhesive structure and the surfacing layer is greater than the adhesive force between the surfacing layer and the fibrous mass of the security paper, so as to cause delamination of the sub-fibrous mass during attempts to peel off the adhesive structure core.
- Another subject of the invention is a process for manufacturing a security paper, in which a differential treatment of a paper fiber mass is carried out to form on one side only of this fiber mass a barrier to non-polar solvents.
- Figure 1 is a schematic sectional view of a security paper according to the invention and an adhesive transparent film capable of being bonded to this security paper
- Figure 2 is a schematic sectional view of an adhesive structure consisting of a security paper according to the invention, having an adhesive face, and
- FIG. 3 is a schematic sectional view of an assembly comprising a security paper according to the invention, on which has been bonded an adhesive structure according to the invention.
- the different figures are schematic, the relative real thicknesses of the different layers not being respected so as to allow them to be better distinguished.
- FIG. 1 shows a security paper 1 comprising a paper fiber mass 2, and on either side thereof, two surfacing layers 3 and 4.
- FIG. 1 also shows an adhesive transparent film 5, comprising a transparent plastic layer 6 and an adhesive layer 7 on one face thereof.
- FIG. 2 shows an adhesive structure made up of an adhesive security paper V, which differs from the paper 1 represented in FIG. 1 by the fact that it comprises a layer of adhesive 9 on the layer 4.
- the assembly 1 "shown in FIG. 3 is formed by gluing the adhesive structure l shown in FIG. 2 to the security paper 1 shown in FIG. 1.
- the surfacing layer 4 forms, in accordance with a aspect of the invention, an impermeable barrier to nonpolar solvents and the fibrous mass
- the outer surface of layer 4 constitutes the first outer face 10 within the meaning of the invention, and the outer surface of layer 3 constitutes the second outer face 11.
- the fibrous mass 2, the layers 3 or 4 may contain chemical reagents to products other than apolar solvents: Reagents to bases, in particular to ammonia or to sodium hydroxide solution, reagents to acids, in particular to hydrochloric acid, reactants with oxidants, in particular with sodium hypochlorite or with hydrogen peroxide, reagents with polar solvents, in particular with ethyl alcohol, denatured or not.
- Reagents to bases in particular to ammonia or to sodium hydroxide solution
- reagents to acids in particular to hydrochloric acid
- reactants with oxidants in particular with sodium hypochlorite or with hydrogen peroxide
- reagents with polar solvents in particular with ethyl alcohol, denatured or not.
- Layer 4 comprises one or more materials making it possible to sufficiently limit the migration of apolar products from the adhesive mass 7 or 9 via the external face 10 to the paper fiber mass 2 or the surfacing layer 3 to obtain the desired result, such materials being for example chosen from film-forming PNAs with a very high degree of hydrolysis, equal to 98% for example, optionally carboxylated, latexes, in particular of acrylic base, or fluorinated resins, and their mixtures, this list being in no way limiting .
- PNA mixed with an acrylic latex makes it possible not to alter the mechanical and printability properties sought for security paper 1 or the, in particular offset and intaglio.
- a sample of security paper was produced by means of a differential treatment consisting in applying to the fibrous mass of the paper, during the step of treatment in a size press, layers surfacing with different compositions for each side.
- a sample of security paper was thus produced in which the first surfacing layer, which corresponds to layer 3 of the example shown in FIG. 1, is produced by depositing a bath having the following composition: - 10% by weight of starch,
- an insolubilizer such as melamine formaldehyde, making it possible to crosslink the starch, a sufficient quantity of reagents reacting with nonpolar solvents, for example 1% by weight,
- the surfacing layer forming a barrier is obtained by depositing a bath having the following composition:
- the bath solutions are deposited at the rate of 40 g / m 2 wet in the example described.
- a sample is also used for comparison, in which the layer 4 forming a barrier is replaced by a layer of composition identical to that of layer 3 but without the reagent with non-polar solvents.
- An aging test is carried out at 80 ° C. for 24 hours, after having stuck on the side of layer 4 for the latter, a protective film coated on the comparison sample and on the sample obtained in accordance with the invention. adhesive.
- the appearance of the two samples is compared at the end of the test. We note on the sample used for comparison the appearance of colored spots while the other sample remained intact.
