Definitions

  • the invention relates to a high-durability paper support for printing a security document, in particular a banknote.
  • the invention also relates to a method of manufacturing this paper medium and a security document made from such a paper medium.
  • Security documents and in particular banknotes are subject to numerous stresses during their circulation. These may be of a mechanical nature, for example folds, creases and other manipulations which may lead to more or less marked deterioration of the fibers or even tearing of the latter.
  • Banknotes made of plastic material are also known, for example those produced on bi-oriented polypropylene (BOPP), presented as products ensuring a high longevity and other hybrid products comprising both parts of paper and other plastic based on polyamides or polyesters.
  • BOPP bi-oriented polypropylene
  • the central banks responsible for the issue, circulation and withdrawal of banknotes have budgetary constraints which force them to seek an increase in the longevity of banknotes, in order to reduce the cost of the cycle of cash, which makes them legitimately turn to the aforementioned solutions.
  • the varnishing of the support is mandatory to guarantee a minimum hold over time.
  • the reinforcing agent consists of additional fibers of a different nature, which are added to the cellulose fibers already usually present in the structure of the paper.
  • the document describes WO 2007/000177 a process for the manufacture of two-ply toilet paper in which, before bringing these two layers together, a softening composition providing a pleasant contact for the epidermis is applied to at least one surface of the outer sheet.
  • the present invention relates to a high-durability paper support for printing a security document, in particular a banknote, comprising cellulose fibers, in a proportion of at least 50% by mass relative to the total mass of the paper support in the dry state, additives and adjuvants, at least one binder, and which also comprises at least one oleophobic and hydrophobic agent based on an organic compound containing perfluoropolyether (PFPE) groups, in a concentration greater than 0% and less than or equal to 5% by mass in the dry state relative to the total mass of the paper support in the dry state,
  • PFPE perfluoropolyether
  • This support also comprises at least one non-fibrous structural reinforcing agent from the family of softening agents, that is to say agents increasing the flexibility of cellulose fibers, in an amount of between 0.5% and 15% by mass relative to the total mass of the paper support in the dry state.
  • the invention also relates to a security document which comprises a support according to one of the preceding characteristics.
  • said document is a banknote.
  • the structural reinforcing agents and the oleophobic and hydrophobic agents are applied offline, separately or as a mixture, by coating, dipping, impregnation, surfacing, spraying, air knife coating, curtain coating, pencil coating, roller coating engraved, appointed or by transfer, type "size press", “film press”, without this list being exhaustive
  • the high durability properties are obtained by a surface treatment which does not require modification of the fibrous composition of the substrate.
  • the air permeability obtained is not zero, contrary to the permeability of the majority of high-durability supports currently known on the market.
  • the Cobb bonding value obtained that is to say the water absorption capacity of the support, is normal and comparable to that of standard banknote paper, which reinforces its printability. Its printing is therefore facilitated.
  • the support as described by the invention retains its barrier properties after crumpling, with in particular permeability and Cobb values which remain relatively low, unlike untreated paper. These characteristics constitute important parameters which enable the support to better resist mechanical stresses when it is in circulation in the field.
  • the support as described by the invention has increased resistance to bending while retaining normal overall stiffness comparable to standard paper.
  • the fibers used in the composition of the paper support are mainly cellulose fibers.
  • these cellulose fibers are chosen from fibers derived from deciduous wood, softwood, seasonal plants such as cotton, hemp or linen, for example. These different fibers can be used alone or in a mixture.
  • the cellulose fibers used are cotton fibers. This fiber is used for its good physical and mechanical characteristics. Indeed, the long cotton fibers can measure up to 40 mm long, which gives the paper obtained a very good resistance to folding.
  • the paper support in accordance with the invention also comprises non-fibrous additives and adjuvants, preferably chosen from anti-foam compounds, mineral fillers, wet strength agents and sizing agents used alone or in combination. mixture of at least two of them.
  • the antifoam compounds are, for example, agents such as silicones, silicone emulsions, polyethylene glycols, derivatives of polyethylene glycols, synthetic polyalcohols, derivatives of polyalcohols, amide-based antifoams, ester base; surfactants such as oligomers, ethylene oxides (EtO), polypropylene oxides (PPOx); hydrophobic agents such as hydrocarbon waxes, polyethylene waxes, fatty alcohols, fatty acids, fatty esters, ethylene bis(steramide) (EBS), hydrophobic silicas.

  • surfactants such as oligomers, ethylene oxides (EtO), polypropylene oxides (PPOx)
  • hydrophobic agents such as hydrocarbon waxes,
  • anti-foam compounds will be added during the preparation of the paper pulp as well as in the wet end of the paper machine, in order to avoid the formation of foam, or even to destroy it and thus improve the formation of the sheet.
  • the mineral fillers are chosen from colloidal silica, sodium silicates, sodium aluminosilicates, natural or precipitated calcium carbonates, talc, natural or calcined kaolin, alumina hydrate, titanium and barium sulphate, alone or as a mixture of at least two of them.
  • These mineral fillers are added to modify the optical properties of the paper obtained, such as its whiteness, its shine or its opacity, but also its surface properties. Some of these fillers are less expensive than fibers and are therefore added to reduce manufacturing costs.
  • Wet strength agents are thermosetting polymers that are added while the paper is still wet and which crosslink in the paper during its passage through the dryer section. They act as a water barrier once the paper is made.
  • mainly polymers are used which ensure the bonding of the fibers together, such as urea-formaldehyde (UF) resins, melamine-formaldehyde (MF) resins, resins based on polyamidoamine-epichlorohydrin (PAA-E ), glyoxal resins, metal ion complexes alone or as a mixture.
  • UF urea-formaldehyde
  • MF melamine-formaldehyde
  • PAA-E polyamidoamine-epichlorohydrin
  • glyoxal resins metal ion complexes alone or as a mixture.
  • Sizing agents retard the penetration of liquids into the paper. They are implemented either when the paper is still in the wet state (sizing in the mass of the paper), or at the level of the size press (sizing on the surface).
  • natural products are used, such as modified natural resins (resin-based glues), starch or modified starch or synthetic products, such as alkyl ketene dimer (AKD), alkenile succinic anhydride (ASA) and other polymers (eg copolymers based on esters of acrylic acid and maleic acid, acrylonitrile and styrene).
  • AKD alkyl ketene dimer
  • ASA alkenile succinic anhydride
  • other polymers eg copolymers based on esters of acrylic acid and maleic acid, acrylonitrile and styrene.
  • paraffin wax and polyethylene waxes are examples of polyethylene waxes.
  • the fibers, additives and adjuvants are mixed and are bonded together by the use of at least one binder.
  • This binder makes it possible to improve the resistance of the paper in the dry state.
  • the binder is chosen from polyvinyl alcohols, starch, starches, latex, hemicelluloses, CMCs (carboxymethylcelluloses), galactomannans, gelatins or polyamide-epichlorohydrin resins, taken alone or as a mixture of at least two of them.
  • the paper support also comprises an oleophobic and hydrophobic agent.
  • This oleophobic and hydrophobic agent is preferably introduced in the form of an aqueous dispersion based on perfluoro-polyethers (PFPE), having in their chemical formulas the basic fragments -(CF 2 CF 2 O) m -(CF 2 O) n - where m and n are integers.
  • PFPE perfluoro-polyethers
  • This agent can for example be chosen from the Fluorolink ® PFPE range marketed by Solvay. Mention may be made, for example, of the aqueous-based commercial product “Fluorolink P56”.
  • At least one non-fibrous structural reinforcing agent from the family of softeners is added to the fibers, additives, adjuvants and binders mentioned above.
  • the structural reinforcing agent is chosen from surfactants such as cationic surfactants, in particular from quaternary ammonium compounds and cationic polymers.
  • the amount of structural reinforcing agent which can be described as a softening agent, is preferably between 1 and 30% by weight relative to the total weight of the softening composition.
  • the softening agent solution contains water - between 20 and 90%, preferably between 60 and 90%.
  • It may also contain low molecular weight organic solvents such as polyethylene glycol, ethanol, isopropanol, n-propanol, acetone, methyl ethyl ketone, ethylene glycol, propylene glycol, glycerine, used alone or in combination.
  • organic solvents such as polyethylene glycol, ethanol, isopropanol, n-propanol, acetone, methyl ethyl ketone, ethylene glycol, propylene glycol, glycerine, used alone or in combination.
  • the amount of these solvents can be between 0 and 30%, preferably between 3 and 15%.
  • This softening agent can be chosen, for example, from the Aquence FiberPlus® range marketed by the company Henkel. Mention may be made, for example, of the commercial product “Aquence FiberPlus Ultra” or else “Aquence FiberPlus Natural”.
  • Cellulose fibers are suspended in water. The mixture is then refined to generate small fibrous elements which will allow the fibers to intertwine more easily and the sheet to have excellent mechanical resistance.
  • the various additives, adjuvants and binders are added to the fibrous suspension.
  • the structural reinforcing agent can be added at this stage, alone or mixed with the oleophobic and hydrophobic agent.
  • the fibrous suspension is finally purified by gravity to eliminate the impurities, and by filtration to eliminate the agglomerates of fibers which could harm the homogeneity of the sheet.
  • the oleophobic and hydrophobic sizing agent(s) containing the perfluoropolyether groups and the structural reinforcing agent can be integrated into the paper support by coating, dipping, impregnating, surfacing, spraying, coating with air knife, curtain coating, pencil coating, coating by engraved rolls, attendants or by transfer, type "size press", “film press", in line or off line, alone or in combination.
  • the formation of the sheet constituting the paper support can be done with a round-form machine, with or without the addition of a pre-coat under pressure (commonly called in the fiduciary industry "short former"), or with a flat table single or twin jet.
  • a watermark, a security thread, security fibers, hilites, boards, or markers may be integrated into the paper support during its formation.

  • the order of application can be reversed.
  • the structural reinforcing agents and the oleophobic and hydrophobic bonding agents can be added as a mixture either with the various additives, adjuvants and binders in the fibrous suspension, or by the various coating techniques mentioned above, in line or offline.
  • the paper support thus formed is printable and transformable by all known printing and transformation processes and in particular those usually used in the fiduciary industry (offset, screen printing, intaglio, hot deposition, flexography, typography, etc.). It is also possible to varnish it before or after printing.
  • Hydrophobicity is characterized as the resistance to water penetration and is measured using the Cobb test (60 s), according to ISO 535. This is the amount of water absorbed by the substrate in g/m 2 thanks to a cylindrical impregnation template, during a lapse of time of 60 seconds. This is a test that is also common in the paper industry to characterize the absorption of paper.
  • the results can give an indication of the printability of the support. Indeed, if the Cobb value is very low, we can expect a refusal of ink from the support. Conversely, with a value that is too high, it may be difficult to achieve the desired rendering in terms of color intensity.
  • the standard values for a banknote are between 40 and 80 g/m 2 .
  • the creasing was carried out once, on the dry sample of dimensions 6.7 ⁇ 6.7 cm using a device allowing the creasing developed by the "National Bureau of Standards" and marketed by IGT Testing Systems, a device commonly used in the fiduciary field.
  • the sample is wrapped around a fork before being slid in a tube with a cap.
  • This tube is then engaged in a vertical sleeve fitted with a solid rod.
  • the tube must then be pushed in until the counterweight of the IGT apparatus detaches, thus applying a force of 100N to the sample.
  • the crumpled sample is then removed by opening the cap. Finally, the sample is delicately smoothed manually.
  • Oleophobia is measured using a test of exposure to fatty substances.
  • the method used called "Kit Test", uses a mixture of castor oil (fatty substance) and solvents with a high boiling point, namely toluene (aromatic solvent) and n-heptane (aliphatic solvent ).
  • composition whose viscosity and surface tension vary inversely to its aggressiveness, that is to say its impregnation capacity.
  • composition rich in castor oil is at the bottom of the scale, while a composition rich in heavy solvents is at the top of this same scale.
  • the stiffness of the support was also evaluated by the Kodak stiffness measurement according to the ISO 5629 standard.
  • Table 1 shows that the air permeability after crumpling (x8) of the solution according to the invention is more than twice lower than the untreated paper, which unambiguously indicates a destructuring well bottom of the bracket.
  • the solution according to the invention also increases water resistance by two to three times (depending on the face considered), even after crumpling (crumpling x1) compared to the untreated support.
  • the treatment applied therefore retains a significant barrier effect even after the support has been crumpled.
  • the surface roughness of the solution is higher, from 40 to 60% depending on the face considered, than the untreated support. This roughness value can be reduced by calendering if necessary.
  • the oil resistance is significantly improved with a score of 8 obtained in the Kit test on both sides.
  • the results of the double ply test of the solution according to the invention are more than three times superior to untreated Vellum paper thanks to the structural reinforcing agent which provides flexibility to the fibers.

  • Example 1 the treatment applied retains its barrier effect even after the support has been crumpled.
  • Oil resistance is improved by five points on the front and back compared to untreated paper. This result is lower than that obtained in Example 1, a result which can be attributed on the one hand to the difference in application technique ("bar coating” in one case and air knife coating in the other) and, on the other hand, to the roughness values of the treated support which are higher than those obtained in example 1.
