Definitions
- the invention relates to the protection of an object against falsification and / or for authentication purposes and / or to guarantee its integrity, using a thin protective film - notably transparent - made of synthetic material intended to be pasted on one side of an object.
- the object can for example be an official document (passport, identity card, driving license, etc.) bearing variable information (surname, first name, address, etc. of the holder) to be protected against attempts at falsification. .
- the film is transparent. It can also be an official document, a packaging or any product or article on which the presence of the film guarantees the authenticity of the object and / or its integrity (i.e. state that it has not been previously used, or consumed, or violated).
- the film is therefore not necessarily transparent, but incorporates security patterns that are impossible or difficult to reproduce (hologram, anti-photocopying printing, pigments invisible in visible light but visible in non-visible light ).
- adheresive generally designates any composition having the property of adhering under certain conditions, and therefore includes not only self-adhesive (or pressure-sensitive adhesives), but also thermoreactivable or heat-sealable adhesives (or hot glues), and glues in general (mono or multicomponents).
- the solvents used by the fraudsters can be aqueous polar solvents (water, detergent or alcoholic aqueous solution %), or non-aqueous polar solvents (acetone, alcohol, %), or non-polar solvents (hydrocarbons such as gasoline, ether, white spirit ).
- a protective film is already known (FR 2,675,742) comprising patterns printed with an ink composition incorporating at least one pigment soluble in hydrocarbons.
- reagents with polar solvents are colored black and reagents with non-polar solvents are colored blue. These reagents therefore make it possible to reveal an attempt to attack the paper with a solvent. They nevertheless have several drawbacks. In the first place, their reactivity decreases over time until it disappears, so that they cannot provide long-term protection. Secondly, the coloring reaction in contact with the solvents implements poorly controlled chemical processes, and the reactivity of the reactants is not constant depending on the manufacture, so that it is never certain that the quantity of reagents incorporated into the paper during its manufacture effectively triggers the reaction. In other words, these colored reagents cannot be used with high reliability.
- these reagents generally react with the adhesive compositions, which themselves contain solvents, plasticizers and wetting agents, so that they are not compatible with protection by sticking a film onto paper since a reaction is triggered during the application and setting of the adhesive, and even after setting.
- Ink compositions are also known which incorporate reactive pigments which change color on contact with a solvent.
- these reactive pigments react to the adhesive compositions.
- these pigments are also limited in number and in shades of so they offer a small variety of colors and effects, and can be detected by an experienced observer.
- the invention therefore aims to overcome these drawbacks by proposing a method and a product for protecting an object using a film bonded to one face of the object, thanks to which the attempts to detach the film by attack with solvents can be revealed reliably, irreversibly, over a long period of time (without substantial reduction in the effectiveness of detection over time), and this in a manner compatible with the bonding of the film to the object.
- the invention also aims to avoid that this protective function (by revealing attempts to peel off the film) cannot be detected in advance in the protected object, in particular by simple visual observation by informed fraudsters.
- the invention also aims to allow security prints to be made using an ink composition incorporating this protective function by revealing attack attempts with polar solvents and / or non-polar solvents, and which allows to obtain all the desired patterns, colors and effects, as in the case of a traditional ink.
- the invention also aims to propose a method of manufacturing a protection product according to the invention and an object protected by a protection method according to the invention.
- the invention further aims to achieve these goals in a simple and economical manner, in particular by screen printing.
- the invention relates to a method of protecting an object in which a thin protective plastic film is bonded to one face of the object using a layer of adhesive interposed between said face and the object, in order to protect it from falsification and / or to authenticate it and / or to guarantee its integrity, characterized in that at least one impression is interposed between the film and said face of the object , called security printing carried out with an ink composition comprising at least one pigment and a binder curable by air drying, suitable for forming a solid printing layer after drying, and incorporating at least one agent, known as a soluble agent , adapted to dissolve, at least under standard conditions of temperature and pressure, after drying of the binder, in any polar and / or non-polar liquid solvent capable of allowing the detachment of the adhesive when it is placed in contact with this adhesive after bonding, the quantity of agent (s) soluble in the binder being adapted so that the security impression can form at least one visible stain revealing any attempt at detachment using at least one such
- the invention also extends to a method of manufacturing a product for protecting an object, comprising a thin protective film of synthetic material intended to be bonded to one face of the object using a layer of adhesive interposed between said face and the object, in order to protect it against falsification and / or to authenticate it and / or to guarantee its integrity, characterized in that one achieves, on a printing medium, at at least one printing, called security printing, with an ink composition comprising at least one pigment and a binder which is curable by air drying, suitable for forming a hard printing layer after drying, this binder incorporating at least one agent , said soluble agent, suitable for dissolving, at least under standard temperature and pressure conditions, after drying of the binder, in any polar and / or non-polar liquid solvent capable of allowing the adhesive to peel off when it is placed to conta next to this adhesive after bonding, the quantity of agent (s) soluble (s) in the binder being adapted so that the security impression can form at least one visible stain revealing any attempt to peel
- the invention also extends to the product obtained by the manufacturing process according to the invention. It therefore also relates to a product for protecting an object comprising a thin protective film of synthetic material comprising a layer of adhesive with a view to bonding it to one face of the object in order to protect it against falsification and / or to authenticate it and / or to guarantee its integrity, and a security impression produced by means of a solid printing composition containing at least one pigment in a binder, characterized in that it comprises at least one security impression produced with a solid printing composition comprising at least one pigment and a hardened binder incorporating at least one agent, known as a soluble agent, suitable for dissolving at least under standard conditions of temperature and pressure, after drying of the binder, in all polar and / or non-polar liquid solvent capable of allowing the adhesive to peel off when it is placed in contact with the adhesive after bonding, the quantity of agent (s) soluble in the binder being adapted so that the security impression can form at least one visible task revealing any attempt to detach using

- FIG. 12 is a schematic cross section of another alternative embodiment of a protection method according to the invention in which an intermediate printing medium is used
- - Figure 13 is a schematic cross section representing a protected object by the method of FIG. 12,
- Figures 14 and 15 are views similar to Figures 12 and 13 showing another alternative embodiment of the invention.
- the protection product represented in FIG. 1 comprises a support 1 of synthetic material, for example made of polystyrene, carrying a thin protective film 2 of synthetic material, preferably transparent, a layer of adhesive 3, a security impression 4 incorporated in reserves. formed in the thickness of the adhesive layer 3, and a protective non-stick paper 5 covering the adhesive layer 3.
- the film 2 is, in the example shown, a multilayer film comprising two layers of polyurethane 2a, 2b, with, interposed therebetween, an intermediate print 6 of security patterns which can be authentication and / or anti- photocopy and / or anti-counterfeiting and / or anti-falsification or others.
- This film 2 can be produced by successive screen printing as described for example in EP-0,271,941 or US-5,232,527, directly produced on the support 1 of polystyrene.
- the support 1 is a support of the so-called nonadherent type, that is to say capable of developing only weak bonding forces with most polymers. For example, it is a polystyrene sheet with a grammage of the order of 120 g / m 2 .
- This support 1 is chosen in a format exceeding that of the surface 8 of the object 9 to be protected.
- the film 2 can be produced by successive screen printing on this support 1 using traditional screen printing machines of the snap type (hinged screen) or of the full lifting screen type (mobile screen in translation).
- the support 1 is placed on the plate of the screen printing machine and the screen thereof is filled with a liquid mixture previously prepared from a hydroxylated polyol and an isocyanate.
- a liquid mixture previously prepared from a hydroxylated polyol and an isocyanate.
- polyacrylic resin for example, polyacrylic resin "reference U 8560” and hexamethylene diisocyanate trimerized “reference U 8580” sold by Laboratoires CHIMITEC (FRANCE)
- the quantity of mixture spread on the screen printing screen is adjusted according to the thickness which it is desired to obtain at each layer.
- the first layer 2a of continuous polyurethane varnish is thus printed in a format corresponding to that of the face 8 of the object 9 to be protected, for example rectangular in the case where the object is an official document such as a passport or a identity card with a rectangular face 8 to be protected.
- a discontinuous intermediate printing 6 is carried out forming patterns or wefts on the first printing.
- This intermediate printing 6 can be carried out either from a traditional ink composition, or even from an ink composition according to the invention incorporating a binder comprising at least one agent soluble in polar liquid solvents and / or in non-polar solvents as described below.
- a discontinuous security impression 4 is then produced on the second layer of polyurethane varnish 2b, after a polymerization time of between 12 hours and 24 hours under standard conditions of temperature and hygrometry. This time is determined so that the layer of polyurethane varnish 2b is both sufficiently partially polymerized to avoid any chemical interaction between this varnish 2b and the binder of the security print 4, and to nevertheless allow the correct production of the security impression 4 on the varnish layer 2b (in particular avoiding screen smudging phenomena). It should also be noted that the security impression 4 is produced before the complete polymerization of the layer of varnish 2b.
- Printing of transparent adhesive material is then carried out in order to obtain the adhesive layer 3 by providing reserves in the thickness of this adhesive layer 3 around the patterns of the security printing 4. Preferably, this printing is also carried out. printing of adhesive material 3 before complete polymerization of the last layer 2b of film 2.
- an ink composition suitable for carrying out a screen printing that is to say formed from a liquid solution with a viscosity of between 0.1 Pa. S and 100 Pa, is used. s - in particular between 0.5 and 2.5 Pa. s -.
- This ink composition comprises at least one pigment, and a binder which is suitable for conveying the pigment (s), and for forming a solid and hard printing layer after drying.
- binder any liquid composition suitable for being able to convey at least one pigment during a printing step, and for curing under hardening conditions.
- the binder is of the type curable by air drying.
- This binder incorporates at least one agent, called a soluble agent, which is distinct from a pigment, and which is adapted to dissolve at least under standard conditions of pressure temperature, that is to say under a pressure of 1 order of an atmosphere (10 5 Pa) and a temperature of the order of 23 ° C, in any polar and / or non-polar liquid solvent capable of allowing the adhesive to come off when it is placed in contact with the adhesive after bonding.
- the quantity of agent (s) soluble in the binder is adapted so that the security impression, solid and hard after drying, can form at least one visible task, revealing any attempt to peel off using at least one such solvent, when this solvent comes into contact with this impression of solid security.
- the soluble agent is also soluble in the said solvents in a sufficiently wide pressure and temperature range around the standard conditions, in particular between 0.9 and 1.1 atmosphere (0.9. 10 5 Pa at 1.10. 5 Pa) and between 10 ° C and 30 ° C.
- the soluble agent (s) is (are) chosen in particular according to the nature of the adhesive used to bond the film 2 on the face 8 of the object 9, which itself determines the families of liquid solvents which may be used by the fraudsters with a view to detaching after the film 2 has been stuck on the object 9. It is it should be noted in this regard that, in general, the ink compositions, which can be assimilated to varnishes, are, after curing, much less soluble in polar and / or non-polar liquid solvents than adhesives. Consequently, there are a very large number of solvents which are capable of dissolving the adhesives after drying, without being able to dissolve the traditional ink compositions after drying.
- incorporation of at least one soluble agent in the binder of an ink composition according to the invention therefore makes it possible to make the security imprint 4 at least as soluble, after drying, the adhesive used to bond the film 2 on the face 8 of the object 9. It is therefore generally sufficient to incorporate a soluble agent which (i) has high solubility in the majority of polar and / or apolar solvents, (ii) is compatible with the composition ink and with its implementation to achieve security printing 4, and (iii) does not dissolve in the adjacent layers (film 2 and / or adhesive 3 and / or face 8 of the object 9) during the manufacture of the protection product or when it is applied to an object 9 to be protected.
- the adhesives used in protective products are acrylic resins or polyvinyl acetates (EN A) which have a relatively high solubility.
- at least one soluble agent is used chosen from the group of alkyl acrylates, alkyl methacrylates, their polymers and copolymers.
- This group thus corresponds to that of vinyl compounds, in particular vinyl thermoplastic resins incorporating carboxylic ester functions, that is to say alkyl carboxylates.
- the alkyl group of the carboxylate functions is an aliphatic alkyl comprising at least two carbon atoms.
- solubility of these vinyl compounds in many solvents increases with the chain length of the alkyl, with the number of carboxylate functions, and, in the case of a polymer or copolymer, with the degree of association between them of monomer molecules.
- a polymethacrylate of isobutyl is used as soluble agent.
- Such a compound achieves an advantageous compromise by resistant to solvents of adhesives based on acrylic or ENA but by remaining soluble with a solubility similar to that of these adhesives in solvents capable of peeling off these adhesives, in particular solvents based on aliphatic hydrocarbons.
- soluble agent at least one chemical compound having a low molecular weight - notably less than 5000 -, which will be soluble in the majority of polar and / or non-polar solvents.
- this soluble agent can be dissolved in a solvent which is a volatile solvent (drying in ambient air or in hot air), for example propylene carbonate .
- Said solvent is of the air-drying type insofar as a multicomponent or photopolymer solvent or drying by chemical reaction is likely to generate compounds with long carbon chains which will not subsequently be soluble in polar solvents and / or in non-polar solvents.
- the binder of the liquid ink composition used to make a security impression can be formed from several different soluble agents which are in solution in the same solvent, or even from a mixture of several liquid compositions each containing at least one soluble agent. , which is in solution in a particular solvent (provided that the different solvents of the different liquid compositions are compatible when mixed together). It is thus possible, for example, to use a binder comprising an agent soluble in aqueous polar solvents (in particular in water), an agent soluble in non-aqueous polar solvents (in particular in alcohols), and an agent soluble in non-polar solvents (in particular in hydrocarbons) .
- binder compositions incorporating one or more such soluble agents can be used.
- a binder formed from a mixture of a reference solution "solubilis” marketed by Laboratoires CHIMITEC (FRANCE), which incorporates an isobutyl polymethacrylate and turns out to be soluble in non-polar solvents and with non-aqueous polar solvents, and a liquid solution called white fugitive water cutting, reference “889202” sold by the company SICPA (SWITZERLAND), which turns out to be soluble in water and aqueous polar solvents.
- the binder can also be formed from only one of these two solutions. It is thus possible to use each of these solutions in a proportion of 0% to 100% by volume.
- the binder comprises a volatile solvent which can be used as a volatile solvent for the ink composition used to achieve security printing.
- the ink composition is then formed from the mixture of one or more binder (s) as mentioned above and one or more pigments.
- An example of an ink composition according to the invention is as follows (the proposals being given in volume): - 60 to 65% of volatile solvent containing at least 10% - especially predominantly - of propylene carbonate,
- pigment chosen from organic visible pigments, mineral visible pigments, invisible organic photoluminescent pigments, invisible mineral photoluminescent pigments,
- the binder can also comprise a non-zero proportion of agents other than soluble agents and their solvents, for example retarding agents, wetting agents, anti-foaming agents, etc.
- the quantity of agent (s) soluble in the binder must be sufficient for the security impression 4 to dissolve and form a task visible to the eye when it is placed in contact with a solvent capable of dissolve the adhesive. It must also be low enough to allow the implementation of the ink composition to achieve security printing 4.
- the dry extract of the binder comprises a proportion of soluble agent (s), generally between 90% and 95% (volumes) such that, after drying, the printing layer formed by l security impression 4 comprises at least 25% - in particular between 25% and 90% - of soluble agent (s).
- the binder must also be adapted to be compatible with the pigment or the various pigments (distinct from the binder and therefore from the soluble agent (s)) incorporated in the ink composition.
- pigment one or more pigment (s) visible in visible light and / or one or more pigment (s) invisible under lighting in visible light and photoluminescent (s) under lighting can be used. minus a source of invisible light, for example a source of ultraviolet rays.
- the security printing can be carried out in one or more passes, in particular to obtain colored patterns.
- the security impression may be of discontinuous type and have the shape of a screen (formed of more or less tightly separated points, deposited in a uniform density or no), or patterns (images, signs, letters). It can also be a uniform continuous type of printing, extending opposite the entire surface of the film 2.
- the adhesive layer 3 can be formed from any adhesive composition.
- a pressure-sensitive adhesive such as an acrylic adhesive composition, in particular of the type sold by Laboratoires CHIMITEC (FRANCE) under the reference "AD73EPSR” or a reactivable adhesive with hot printed at room temperature compatible with the polyurethane varnish layer 2b, in particular a thermo-activated adhesive formed from a copolymer in aqueous dispersion such as an adhesive reference "ADTH50” or "ADTH21” sold by Laboratoires CHIMITEC (FRANCE).
- a self-adhesive it suffices to peel off the silicone paper 5, to apply the film 2 in contact with the face 8 of the object 9 to be protected (FIG.
- FIG. 4 shows a second embodiment of the product according to the invention, similar to that of FIG. 1, except that the layer of adhesive 3 is a continuous layer extending over the entire surface of the film 2, and a security impression 4 is subsequently produced directly on this layer of adhesive 3.
- this layer of adhesive 3 it is necessary for this layer of adhesive 3 to be a layer of heat-sealable adhesive without "tack", that is to say i.e. without initial instant membership.
- the third embodiment shown in FIG. 5 differs from the previous one in that the security printing 4 is carried out first on the second layer 2b of polyurethane varnish, then the layer of adhesive 3 is printed above the printing Security 4.
- any adhesive layer 3 can be used, as in the case of the first embodiment.
- the adhesive compositions which can be printed by screen printing incorporate solvents, it is found in practice that it is possible to screen print a layer of adhesive 3 on a security print 4 incorporating a soluble-in particular agent a polymethacrylate of isobutyle- or, conversely, a security imprint 4 of such an adhesive layer 3, without the ink binder composition according to the invention (incorporating at least one soluble agent) used for security printing 4 does not dissolve on contact with the adhesive layer solvent, even though the binder for security printing dissolves when it is subsequently brought into contact with a solvent as shown in the figure 3. No clear explanation for this surprising result can be given.
- FIG. 6 makes it possible to avoid, in cases where this is deemed necessary, any contacting of the security impression 4 with an adhesive before the film 2 is placed on the object 9.
- a protective film 2 similar to that shown in FIG. 1 is used and comprising a continuous layer of adhesive 3, this film 2 being carried by a support 1 made of polystyrene and the adhesive layer 3 being coated with a protective silicone paper 5.
- This product therefore constitutes a traditional product as described in EP-0,271,941 or US-5,232,527.
- a security impression 4 is produced with an ink composition as described above (incorporating at least one pigment and a binder comprising at least one agent soluble in polar solvents and / or in non-polar solvents) not on the film itself, but on the object 9. that is to say on the face 8 of the object 9 to be protected.
- the film 2 is then applied to the face 8 while covering the security impression 4 to obtain the protected object 9 as shown in FIG. 7.
- FIG. 8 represents another alternative embodiment in which the security impression 4 is carried by the film 2, while the adhesive layer 3 is produced on the face 8 of the object 9.
- the object is obtained 9 protected as shown in FIG. 9 which incorporates the security impression 4.
- the binder of the security impression does not dissolve when the adhesive 3 is applied to the security impression 4, when the impressions are produced by screen printing.
- FIG. 10 represents a fourth embodiment of the invention in which the protective film consists of a film 10 monolayer, for example in transparent polyester carrying a layer of polyethylene 11 forming a heat-sealable adhesive. On this layer 11 of heat-sealable adhesive, a discontinuous security impression 4 was produced by screen printing as described above.
- FIG. 11 shows a fifth embodiment in which a continuous security impression 12 is produced directly on a monolayer film 10 of synthetic material such as polyester or polypropylene, then this security impression 12 is covered with a layer of adhesive 13 which can be a self-adhesive or a heat-sealable adhesive. This adhesive layer 13 is applied by screen printing, like security printing 12.
- the security printing 12 extends over the entire surface of the adhesive layer 13, at least substantially in the same format as the film. 10.
- This security impression 12 is produced with an ink composition comprising at least one pigment and a binder comprising at least one agent which is soluble in polar solvents and / or in non-polar solvents, as described above.
- a pigment visible in visible light but photoluminescent in invisible light, for example a photoluminescent pigment in ultraviolet light.
- One or more visible pigments can also be used.
- the multilayer complex formed by the film 10, the adhesive layer 13 and the security imprint 12 can be completely transparent (in the case of a photoluminescent pigment under ultraviolet for example) or translucent (in the case of a visible pigment with a low dosage ) or opaque (in the case of a highly dosed visible pigment), depending on the applications envisaged.
- the assembly In the case of application as protection against falsification of variable inscriptions on official documents, the assembly must be transparent to allow normal viewing of said variable inscriptions.
- the complex In the case of an application as authentication or as a guarantee of the integrity of a document or of packaging, the complex may be translucent or opaque.
- the film 2, 10 is itself transparent so as to allow the visualization of the tasks. resulting from the solubilization of the security impression 4, 12 in the event of an attempted fraud. However, this is not strictly necessary in certain applications where one can be satisfied with detecting fraud attempts only after peeling off the film.
- the adhesive layer 13 and the continuous security printing 12 can be combined not by screen printing, but by other printing modes, for example by laminating in continued.
- a non-stick protective paper 14 is also provided on the last layer of the protection product.
- FIG. 12 represents another alternative embodiment in which security impressions 15, 16 are produced not on a protective film or on the object 9 to be protected, but on an intermediate film 17 formed of one or more layers of adhesive or varnish carried by a support 18.
- Such an intermediate film 17 carried by its support 18 forms an intermediate sheet which can in particular be used for producing variable inscriptions, as described for example in FR-2,763,883.
- a security impression 15 similar to that described above is first produced (incorporating at least one agent soluble in polar solvents and / or non-polar solvents) on the support 18, then printing is carried out.
- variable inscriptions were also printed by any desired printing means (manual, laser printing, inkjet printing, etc.).
- the support 18 itself can be a paper and / or a monolayer or multilayer synthetic film which is not adherent on most polymers, and in particular a polystyrene support.
- the object 9 to be protected initially bears, on its face 8 to be protected, inscriptions 20.
- the protective film used in this variant may be a monolayer polyurethane film 22 produced by screen printing on a polystyrene support 21 with a continuous adhesive layer 23 such as described in EP-0.271.941 or US-5.232.527.
- the adhesive layer 23 is nevertheless preferably formed from a heat-activated adhesive.
- the intermediate film 17 is hot-rolled on the face 8 of the support 9 to be protected, then the support 18 is removed, then the film 22 is hot-rolled on this intermediate film 17, then the support 21 is removed.
- the security impressions 15, 16 are interposed between the film 22 and the object 9.
- FIG. 14 represents an alternative embodiment similar to FIG. 12, but in which the intermediate film 24 is formed of a single layer 24 of polyurethane varnish produced by screen printing on the support 18. A security printing 25 is then carried out on this intermediate film 24. A second security impression 26 is also produced on the adhesive layer 23 of the film 22.
- the object 9 to be protected carries an adhesive layer 27 previously produced on its face 8 covering the inscriptions 20.
- the adhesive layers 23, 27 in this alternative embodiment can be pressure-sensitive self-adhesive or thermoreactivable adhesive.
- the intermediate film 24 is applied to the adhesive layer 27 of the object 9, the support 18 is removed, then the film 22 is applied to the intermediate film 24, then the support 21 is removed.
- the security impressions 25, 26 are interposed between the film 22 and the object 9.
- the protective product according to the invention is formed in two parts: the film 22 on its support 21 and the intermediate film 17, 24 on its support 18.
- the security prints 15, 16, 25, 26 are not all produced on the film itself, but also on the support 18 of the intermediate film and / or on this intermediate film itself, which thus act as print media for these prints of security. But, in any case, we print the security prints on printing supports (film and / or intermediate film and / or support of film or intermediate film) which are adapted to allow each security impression 15, 16, 25, 26 to be interposed between the film 22 and object 9.
- - product 1 in accordance with FIG. 1, of rectangular format of 80mm x 120mm, with a film 2 of thickness of approximately 45 ⁇ m
