Definitions
- the present invention relates to a method for securing valuable documents, in particular banknotes, and more particularly to a method for securing valuable documents contained in a security protection or transport enclosure, said method comprising an exposure step said documents to external microwave radiation, especially in case of emergency.
- a solution proposed by AXYTRANS particularly in patent EP 188155, consists in triggering a pyrotechnic charge housed in the lid of the secure container, the deflagration of said charge causing both the opening of liquid tanks. marker or destroyer placed inside the container and the partial or total cutting of all valuable documents. Even if this solution leads to a deterioration or a deep marking of the banknotes, the result is still insufficient both in terms of the proportion of notes physically reached by the liquid, as the level of the regularity of said deteriorations or said markings. .
- this solution does not control the intensity, shape and positioning of said deteriorations or said markings.
- This heterogeneity in the physical modification undergone by each of the notes leaves a doubt as to the origin of said modifications and, as a result, does not make it possible to reliably identify a stolen ticket of a non-stolen ticket.
- the use of a pyrotechnic charge may present a potential danger to the personnel in charge of the transport of funds, which forces to adopt relatively precise and tedious safety procedures when handling such containers.
- Another prior solution implements the prior incorporation into valuable documents of an active element capable of converting into heat energy received from an external electromagnetic source, from preferably a microwave radiation.
- the heat created causes, as the case may be, a melting of said active element, or a local combustion of the document of value at said active element, thus visibly modifying the appearance of the document.
- the risk in this solution is to lead, in one case, to an uncontrolled combustion of documents and, in fact, the secure container itself, thus exposing those present, on the one hand, to gaseous releases generally toxic and, on the other hand, a serious threat of fire.
- the active element became liquid flows through the pores of the paper in a relatively random path, ultimately resulting in non-homogeneous changes from one document to another. This solution is therefore also unsatisfactory in view of the problem.
- One of the aims of the invention is therefore to propose a new method for securing valuable documents that does not have the drawbacks of the abovementioned prior art and, in particular, a method of securing valuable documents that makes it possible to achieve in a simple and fast way, while being without risk for the potential users, with an irreversible physical modification of the valuable documents, rendering said documents unusable or legally identifiable, said modification that can be made in a complete, homogeneous and controlled manner on all the valuable documents.
- a method for securing valuable documents comprising a step of exposing said documents to external microwave radiation, especially in an emergency, remarkable in that it comprises a step of integrating into each document, during its manufacture, at least one active substance able to release a gas following a chemical reaction of said active substance triggered by said external microwave radiation to which it is exposed, said gas being released in a quantity and at such a speed that the appearance of the valuable documents is degraded, this degradation rendering said documents unusable or legally identifiable.
- the gas released is dinitrogen.
- the active substance comprises at least one function capable of releasing a molecule of dinitrogen during exposure to the external microwave radiation, said function being chosen from the group comprising the diazo, diazonium and azide functions.
- the active substance is a molecule having at least one diazo function and corresponding to formula (I):
- R 1 and R 2 which are identical or different, represent, independently of one another, a radical alkyl, cycloalkyl, an aromatic ring, a heteroaromatic ring, substituted or not by heteroatomic groups, which may themselves comprise at least one function selected from the group comprising the diazo, diazonium and azide functions.
- the chemical modification of the active substance is accompanied by the irreversible release of at least two products of the reaction, namely a first product being an organic group of the carbene type and the second product of the reaction being at least a molecule of dinitrogen, according to the following scheme 1:
- the active substance is a molecule having at least one diazonium function and corresponding to formula (II):
- R 3 -N N (II) in which R 3 represents an alkyl, cycloalkyl, an aromatic ring or a heteroaromatic ring, substituted or not by heteroatomic groups, which may themselves comprise at least one function selected from the group comprising diazo, diazonium and azide functions.
- the active substance is a molecule having at least one azide function and corresponding to formula (III):
- R 4 represents an alkali metal selected from the group consisting of sodium, potassium and lithium, an alkyl, cycloalkyl, an aromatic ring, a heteroaromatic ring, substituted or unsubstituted by heteroatomic groups, which may themselves comprise at least one function selected from the group consisting of diazo, diazonium and azide functions.
- the chemical modification of the active substance is accompanied by the irreversible release of at least two products of the reaction, namely a first product being an organic group of the nitrene type and the second product of the reaction being at least a molecule of dinitrogen, according to the following scheme 3:
- R 4 N NN- *.
- the active substance has several functions diazo, diazonium and azide, so that the chemical modification of the active substance following exposure to microwave radiation results in the release of several molecules of inert gaseous dinitrogen per active molecule.
- the heteroatomic groups as defined above may comprise functions chosen from the group comprising the ester, ether, alcohol, amino, thiol, carboxylic acid, nitrile, aldehyde, nitro, and halogen.
- the aromatic ring may be a mono or polycyclic aryl radical.
- the monocyclic aryl radical may be a phenyl radical which may or may not be substituted by one or more alkyl radicals.
- active substance sodium azide or an active substance corresponding to formula (HIa):
- the active substances used in the present invention have the property of being thermally stable, their decomposition temperature being greater than 200 ° C.
- the active substances used following a chemical reaction caused by exposure to microwave radiation, make it possible to release gaseous dinitrogen in an extremely fast reaction that can be likened to an explosion.
- the valuable document is then physically degraded irreversibly, this degradation rendering said document unusable or legally identifiable.
- the gas generated during this chemical reaction is perfectly inert and therefore safe for potential users.
- the active substance there is added to the active substance a chemical dopant accelerating the chemical reaction triggered by said external microwave radiation.
- the chemical dopant has good conductive properties. From 1% to 10% by weight of chemical dopant can be used. For example, single-walled carbon nanotubes (SWNTs) may be used. Thanks to the chemical dopant, the deflagration of the active substance under microwave radiation will occur much more quickly. Decreasing the degradation time is an essential point in the quality of the process according to the invention.
- the integration of the active substance with valuable documents is carried out by incorporating said active substance into at least one of the constituent elements of said valuable documents.
- the active substance is incorporated into the carrier of base of the valuable documents, said support being able to be made of paper or plastic, in particular the paper of the banknote.
- the active substance is incorporated in a varnish covering said valuable documents, for example an overprint varnish deposited on the valuable documents to be secured.
- the active substance used in the present invention is colorless or weakly colored and is therefore imperceptible in the latent state.
- the active substance is incorporated into an ink printed on said valuable documents, whether the ink is offset, serigraphic, flexographic, typographic, or inkjet, but also of any type of material adapted and applied on the valuable document.
- the ink used may be an intaglio type ink, specific to the trustee, which has the characteristic of a large deposit and adjustable (thickness of 20 to 100 microns).
- the present invention also relates to a valuable document capable of being exposed, particularly in case of emergency, to external microwave radiation, comprising at least one active substance as described above, capable of releasing a gas following a chemical reaction of said active substance triggered by said external microwave radiation to which it is exposed, said gas being released in a quantity and at a rate such that the appearance of the valuable document is degraded, this degradation rendering said document unusable or legally identifiable.
- the valuable document constitutes a bank note.
- Preparation In a first step, 5.2 g of sodium azide (NaN) are added to a solution of aqueous-based acrylic lacquer (30 ml) having the reference 803 675 W in the PROTECT® range marketed by SICPA. 3 ) marketed by the company Acros (CAS: 26628-22-8).
