Definitions
- the present invention relates to a security information medium for recording and storage of static and dynamic information relating to the traceability of a product.
- This support is plastic and includes magnetic particles, it is in particular in the form of a label or plastic packaging sheet.
- the present invention also relates to a method of manufacturing said support and a method of reading recorded information and stored.
- the information is recorded magnetically using inductive heads but their reading is done by reading machines equipped with magneto-resistive sensors as it will be explained below.
- Another example is linked to acts of counterfeiting carried out for the imitation of major brands or drugs or products with serious safety consequences people or property.
- Another example is related to the diversion acts putting the products authentic in distribution circuits parallel to selective distribution networks or. exclusive. Similarly, when products are found to be defective in use, it is imperative to be able to find them to withdraw, exchange or revise them.
- Traceability is a legal obligation in the case of certain products as for automobiles and their spare parts, for products subject to approval; medication subject to marketing authorization or certain food products. More generally, according to the European directive of June 29, 1992 relating to product safety, all companies must be able to provide proof of product conformity to the general regulations.
- traceability is defined as "the ability to find the history, use or location of an entity by means of identifications saved ”.
- ISO 9000-2 of July 1994 relating to the application of standards for quality management and quality assurance which takes up the content of ISO 9000-2: 1993 where details are given on page 10, point 4.8 of the recommendations on the identification and traceability of a product.
- Traceability applies to the monitoring of a group of same articles, bearing the same number lot as a reference, called statistical identification, or to individually identified objects, called registration, or a sequential identification of operations or operators identified.
- linear bar codes (1D) in particular the so-called logistics bar code which symbolizes the translation of the EAN 128 standardized coding system, the most dense in information currently used for logistical monitoring of a product. It symbolizes at the times the information concerning the compulsory main identifier (date of manufacture and / or number batch) and additional information relating to the logistics unit (information concerning the manufacturing. transport and customer), to ensure product traceability from its manufacture to its point of sale.
- a disadvantage of this type of barcode is that it requires tolerances for direct printing difficult to obtain with any medium. For example, if the media printing is porous, it will absorb too much printing ink and will not allow small, well-defined printouts, otherwise the code will be difficult to read.
- Another downside is that the amount of information it can contain is limited.
- the codes appeared two-dimensional bars (2D), which are formed by a stack of several linear bar codes appearing in the form of a checkerboard and, more recently, matrix codes have appeared which do not are no longer in the form of bars, but of light and dark dots or squares. They require specific decoding software which does not allow very fast data processing.
- microchip Another way to record the traceability of a developing product is the microchip.
- This chip is incorporated into a label or directly into the product. Although it has the possibility of storing static and dynamic information at the same time, it has the disadvantage of being too large (around 2 mm 2 ) to be discreetly incorporated into a label or packaging or the product itself; it is all the thicker when it is activated, that is to say when it is implemented with an induction winding which supplies it with the operating energy and taken up in resin. Its lack of flexibility limits its incorporation into rigid supports. Furthermore, its cost price is high.
- the chip can be located easily, by visual identification or by touch. It is not truly inviolable, it can be removed and replaced by another.
- patent US5520954 a method of preparing a dispersion has been described. magnetic comprising gelatin and to be applied in a layer on a film photographic to allow data recording, the layer obtained not having to interfere with the photographic properties of the film.
- This patent does not concern the field of the invention which is that of security supports.
- the problem is therefore to provide an information medium allowing the traceability of a product and / or process, which is invisible and difficult to spot without knowing in advance its location, and which presents an important and evolving memory, that is to say which allows to record and store a large amount of information and some being static and others dynamic.
- this support must be compatible at least with one of the anti-theft systems known as electromagnetic devices (magnetic tab or fine alloy), circuits electronic devices remotely detectable by radio frequency or magnetoacoustic devices (vibrate and emit a frequency of 58kHz), that is to say that it must not disturb the detection, activation and deactivation of these various devices.
- electromagnetic devices electromagnetic tab or fine alloy
- circuits electronic devices remotely detectable by radio frequency or magnetoacoustic devices vibrate and emit a frequency of 58kHz
- Another property sought in addition to traceability is to be able to evidence of an attempt to tamper with a product; for example, when replacing a product given by another in a bottle, bottle or box.
- Another secondary property sought in addition to traceability is compatibility with known means of authentication (so-called security elements) in the field of security documents, such as optically variable devices (holograms, iridescence, diffraction gratings, moiré, thermochromic effect ).
- An object of the present invention is therefore to provide an information medium allowing the traceability of a product which solves the problems of the means of the prior art and can present in addition to the desired secondary properties set out above.
- Another object of the present invention is to be able to encode information in quantity increased compared to bar codes.
- coating on the surface of the substrate is meant that it is a coating which is not not necessarily, at least in part, covered by a masking layer, said coating possibly be present on the external surface of the substrate or be under or between other layers which do not not mask at least in part.
- magnetic particles do not affect the appearance characteristics of the said area 'means that it is not necessary to hide said area to make it invisible and more particularly means that when they are included in the mass of the substrate, or even when included in a surface coating the surface of the substrate, the particles as such are not distinguished and the appearance, in particular the brightness (L *) and / or colorimetric coordinates (L *, a *, b *) in the CIELAB system, and / or the transparency or the opacity of the substrate is not or very little modified.
- the brightness L * is greater than 70 and preferably 80.
- Known fillers providing whiteness such as for example titanium dioxide or calcium carbonate can be added to improve whiteness, in particular at rates between 2 and 10%, in the case of white substrates.
- said support has a thickness of between 1 and 2000 ⁇ m, preferably between 1 and 800 ⁇ m and more preferably between 10 and 600 ⁇ m.
- the present invention is particularly advantageous when said support is a label or a packaging sheet or film.
- the invention makes it possible to associate in the same zone properties magnetic and an authentication element like those known in the field of security documents, in particular for visual effect, such as certain security threads, devices with variable optical effect such as diffraction gratings, holograms, moiré patterns, iridescent effect prints or bands, prints based on thermochromic inks or other.
- visual effect such as certain security threads
- devices with variable optical effect such as diffraction gratings, holograms, moiré patterns, iridescent effect prints or bands, prints based on thermochromic inks or other.
- the visual effect or readability is not obscured by the presence of particles magnetic.
- the magnetic particles can therefore be associated with authentication elements (also called security elements).
- anti-theft devices can coexist with the presence of particles magnetic.
- Said support with said particles can also make it possible to record and store information, in much larger quantities than previously, especially under form magnetic codes, and render the area where the magnetic information was recorded and stored invisible to the naked eye and invisible with a magnifying glass. It also allows you to record and read additional information to the initial information to follow the traceability of a product. Indeed with magneto-resistive sensors having a much higher sensitivity to heads inductive previously used, we can read encoded magnetic information or simply characterize the saturation or remanent magnetization of the pigments, this at concentrations of very weak magnetic particles, in particular, lower than the concentrations allowing a detection by inductive sensors, but making the presence of said particles invisible Such support is therefore inviolable because the areas containing the information cannot be located easily.
- the magnetic particles do not form agglomerates or aggregates inhomogeneous. It is therefore necessary that magnetic particles are well individualized and uniformly dispersed and distributed in their substrate.
- uniform distribution magnetic particles as the particle density in the area, and therefore the magnetic saturation or remanent magnetization in said zone are substantially constant so that there is little or no background noise. This feature is necessary to allow to read reliably a coded message, recorded in said zone.
- a secondary aim of the present invention is therefore to confer on a support, the ability to be magnetized, recorded, detected and read by machine thanks to its magnetic properties, without it it is necessary to mask the magnetic zones to make them invisible and in particular to ability to introduce magnetic particles homogeneously and without aggregates on the surface or in the mass of a substrate over a wide area.
- the magnetic particles can therefore be advantageously incorporated into the mass. of the substrate by mixing a dispersion of said particles with the base mixture to make the substrate or the coating of said information medium. This gives good individualization of the particles, which prevents re-agglomeration of said particles when incorporated into the manufacturing medium of said substrate or said coating.
- the particles magnetic then come in the form of pigments which can be coated with a layer, even discrete (ie not continuous) coming from the dispersion medium.
- Said area comprising said particles may cover the entire substrate or a part only.
- magnetic particles in the mass of the substrate or in a coating on the surface of the substrate in an area covering the entire substrate, allows to considerably expand the possibilities of using the present invention. However they may only be in a localized area, in particular in the form of a strip, in particular of width from 1 to 5 cm by methods known to a person skilled in the art, said zone not covering necessarily the entire substrate.
- the present invention is particularly advantageous when the substrate comprising said magnetic particles is a transparent to translucent plastic substrate and / or has a light color, especially white, cream or pale yellow.
- the brightness L * of the CIELAB system is greater than 70 and preferably more than 80.
- the ISO whiteness according to ISO 2471 is preferably greater than or equal to 60% and the whiteness CIE according to the CIELAB formula is preferably greater than or equal to 20%.
- this coating can consist of an ink or a varnish or a composition coating or adhesive, which can be applied respectively by a technique printing or coating.
- the coating composition may especially include, in addition to said magnetic particles, a binder chosen from polyvinyl alcohol (PVA) type binders, or other water-soluble binders or polymers in aqueous dispersion (latex), fillers coating, water and additives.
- the varnish may especially include, in addition to said particles magnetic, polymeric binder, solvent and additives.
- the coating composition can be applied by means known to those skilled in the art with coating facilities, such as metal blade coater, air knife coater, CHAMPION type rotary bar coater, pre-dosed film transfer coater.
- inks or varnishes particular mention is made of printing inks or varnishes which can be applied by gravure printing, intaglio printing, offset printing or screen printing over a thickness of 1 to 5 ⁇ m.
- printing varnishes mention may be made of soluble varnishes in aqueous medium or in organic solvent which are dried by evaporation, and the varnishes fixed by UV or electronic radiation ("electron beam").
- said coating can advantageously be transparent or translucent.
- the holograms or holographic security strips consist of multilayer complexes [(1) for holograms: adhesive layer, embossing lacquer, aluminum and protective varnish; (2) for holographic bands: the same layers as for holograms but applied to the at least one layer of polyester, said strip being coated on its external faces with varnish heat sealing]. Then to have magnetic properties, you had to apply a layer magnetic in these complexes by an additional operation, the layer being moreover dark and thick.
- holograms are sometimes transparent holograms, say non-metallic or partially demetallized holograms.
- the presence of a layer dark magnetic is on the one hand incompatible with the transparency properties of the hologram and on the other hand, resists the partial demetallization treatment of the hologram, making it impossible to carry out an inscription with recesses of the so-called “Cleartext” type.
- the present invention makes it possible to associate magnetic particles with holograms of advantageously. To do this, simply mix the magnetic particles with the layers component of the hologram, such as the adhesive layer, the embossing lacquer, the protection or in the hologram adhesion primer.
- the layers component of the hologram such as the adhesive layer, the embossing lacquer, the protection or in the hologram adhesion primer.
- the hologram constitutes a holographic strip
- magnetic particles in the mass of said strip (such as a polyester substrate) or in a heat-sealing adhesive or varnish allowing the adhesion of said strip to the support.
- An additional advantage of holographic tapes is to obtain a hologram at magnetic property without affecting traditional manufacturing processes and without increasing its excessively thick.
- the invention also provides a medium for recording information static and dynamic which can be a holagram.
- a medium for recording information static and dynamic which can be a holagram.
- the mixing of magnetic particles in the mass of the substrate or a transparent to translucent coating allows them to be distributed uniformly over the entire surface of the support and superimpose them on inscriptions or patterns, negative or positive, without alter their visibility and appearance.
- the support allowing the recording of information static and dynamic is an integral part of the object relating to said information
- the medium can be the object itself.
- This variant can be applied to plastic security documents and in particular to plastic banknotes whose traceability is to be followed or to an official document such as a passport cover, an identity card or a driving license or to a substrate intended for the manufacture of such an official document, in which said magnetic particles are applied in the mass of said substrate or in a coating on the surface of the substrate.

- the magnetic information can be presented according to various embodiments.
- the support includes magnetic particles in at least one continuous area and recording bits logic is done by magnetization with fields whose direction of magnetization is reversed in localized regions.

- the so-called medium coercivity materials have a coercivity between 32.10 3 and 135.10 3 A / m (approximately 400 to 1700 Oe) and are generally iron oxides doped with cobalt or chromium dioxides.
- the so-called high coercivity materials have a coercivity between 135.10 3 and 800.10 3 A / m (around 1700 to 10 000 Oe), such as barium or strontium ferrites, in particular BaFe 12 O 19 or SrFe 12 O 19 respectively. commonly used.

Description
Un autre inconvénient est d'être un support d'information à mémoire permanente et donc de ne pas être à mémoire évolutive. En effet, une partie des informations peut être fixe (dites informations statiques) comme la date et le lieu de fabrication, les matières premières entrant dans la fabrication, numéro de lot, alors qu'une autre partie des informations peut varier et être individualisée (informations dites dynamiques) en fonction de la circulation du produit.
Un autre inconvénient est la place importante qu'ils prennent sur l'objet du fait de leur taille ; il est donc difficile de les appliquer sur un objet de petites dimensions.
Un autre inconvénient est leur manque d'esthétique, ce qui peut s'avérer particulièrement gênant lorsqu'ils sont portés sur des emballages de luxe ou sur des contenants (flacons, bouteilles...), notamment à formes et/ou motifs recherchés.
La puce peut être localisée facilement, par repérage visuel ou au toucher. Elle n'est pas véritablement inviolable, elle peut être enlevée et substituée par une autre.
- lesdites particules magnétiques sont comprises dans la masse du substrat ou dans un revêtement à la surface du substrat,
- lesdites particules magnétiques n'affectent pas les caractéristiques d'aspect de ladite zone, en l'absence de tout masquage pour les rendre invisibles et,
- lesdites particules magnétiques sont réparties de manière uniforme dans ladite zone et que lesdites
particules vérifient les caractéristiques de concentrations suivantes, prises séparement
ou en combinaison:
- a) lesdites particules magnétiques sont comprises dans la masse dudit substrat ou dans ledit revêtement appliqué en surface du substrat, à une concentration inférieure ou égale à 1 % en poids sec dudit substrat dans ladite zone,
- b) lesdites particules sont comprises dans un revêtement appliqué en surface dudit substrat et la quantité de particules magnétiques dans ledit revêtement (dans ladite zone) est inférieure ou égale à 250 mg/m2.
Par exemple on peut enregistrer et stocker magnétiquement des informations, en particulier des informations numérisées, correspondant à une photographie d'identité et/ou à des mentions variables sans que ces informations soient visibles ou ne perturbe une mise en page normalisée desdits documents. Les avantages de cette solution sont au moins double : il n'y a plus de problème de limitation de place, puisque la surface entière peut servir de support pour enregistrer les informations normalisées, et le lieu où l'information est enregistrée n'est pas visible.
Les matériaux dits de moyenne coercitivité ont une coercitivité comprise entre 32.103 et 135.103 A/m ( environ 400 à 1700 Oe ) et sont en général des oxydes de fer dopés au cobalt ou des dioxydes de chrome.
Les matériaux dits de haute coercitivité ont une coercitivité comprise entre 135.103 et 800.103 A/m (environ 1700 à 10 000 Oe), tels que les ferrites de baryum ou de strontium en particulier respectivement BaFe12 O19 ou SrFe12 O19 sont couramment utilisées.
Des particules magnétiques sont dispersées sous agitation à l'aide d'un agent dispersant, tel qu'un polyacrylate, et éventuellement d'une résine de broyage, ayant une bonne compatibilité avec le milieu auquel elle sera incorporée ultérieurement. La pâte obtenue est ensuite traitée dans un moulin à billes pour détruire les agglomérats et individualiser les particules. La dispersion obtenue comporte 10 % de particules magnétiques en poids sec.
Les feuilles obtenues sont translucides et ont une épaisseur de 300 µm.
Pour 100 parts en poids du copolymère, il y a 0,15 part d'agent antistatique et 0,05 part de particules magnétiques en poids sec.
La bonne lecture des informations confirme la répartition homogène des particules magnétiques et sans réagglomération dans le substrat.
On obtient une étiquette adhésive et magnétique transparente.
On applique cette étiquette sur un flacon en plastique transparent. On n'altère pas l'aspect esthétique du flacon.
On enregistre des informations d'identification (statiques) et des informations dynamiques relatives à la traçabiiité du produit par exemple en réalisant un encodage tel que chaque série d'informations soit séparée par une longue série de bits « 0 ».
Dans une variante, on peut emballer le flacon ainsi étiqueté dans l'emballage de l'exemple 1, et ainsi enregister les mêmes informations à la fois dans l'emballage et dans l'etiquette On a donc un lien entre le produit et son emballage.
La poudre de ferrites de barium est ajoutée sous agitation à une solution aqueuse d'un agent tensio-actif, à la fois mouillant et dispersant, tel qu'un sel d'ammonium du poly(acide acrylique) et éventuellement une résine de broyage ayant une bonne compatibilité avec le milieu auquel elle sera incorporée ultérieurement. La pâte obtenue est ensuite traitée dans un moulin à billes pour détruire les agglomérats et individualiser les particules. Le concentré de particules magnétiques individualisées est ensuite redilué et stabilisé contre la sédimentation des particules par ajout d'un agent modificateur de rhéologie, comme par exemple un gel aqueux de bentonites ou de silices pyrogènées.
La dispersion comporte, en poids sec, 10 pour cent de particules magnétiques.
- on réalise une feuille de polyoléfines de 400 µm,
- on applique sur la feuille par lame d'air, une composition en milieu aqueux comprenant :
- 100 parts en poids sec d'un mélange de carbonate de calcium et de kaolin,
- 100 parts en poids sec d'un liant styrène-butadiène carboxylé introduit sous forme d'une dispersion aqueuse stabilisée (latex),
- 0,35 part en poids sec de particules magnétiques introduites sous forme de la dispersion des exemples précédents.
On réalise un enregistrement d'informations comme à l'exemple 2.
- Sur une feuille de polypropylène, on applique par couchage sérigraphique, un primer d'adhérence qui contient les particules magnétiques. Ce primer est à base d'un polymère styrène-acrylique en milieu aqueux. On a introduit 0,15 part de particules magnétiques sous forme de dispersion magnétique de l'exemple 3 pour 100 parts du primer en poids sec. On a déposé 10 g/m2 en sec du primer contenant les particules.
- On applique une bande holographique transparente d'une épaisseur de 6 µm et qui comporte un adhésif thermoscellable, par la méthode connue du transfert à chaud et sous pression, sur le primer magnétique de la feuille de polypropylène.
On réalise un enregistrement d'informations comme à l'exemple 2 au niveau de la bande holographique.
On relit l'enregistrement sans être gêné par la présence de la bande holographique.
Enregistrement de données magnétiques : pour chaque échantillon, on procède dans un premier temps à un encodage d'un signal de type 2F (série de « 1 ») et on mesure l'amplitude moyenne du signal. On procède dans un deuxième temps à un encodage avec un signal F/2F de basse densité (10 bits par pouce, soit environ 10 bits pour 2,54 cm) du type « 1-1-0-1-0 ».
Cet enregistrement est fait à l'aide d'un appareil à double tête d'enregistrement inductive classique (l'une pour les matériaux à basse coercitivité et l'autre pour les matériaux à haute coercitivité) ayant un entrefer d'écriture de 100 µm. La largeur d'écriture est de 6,5 mm et la vitesse d'enregistrement est de 200 mm/s. Le courant d'écriture a été sélectionné à 250 mA afin d'obtenir un signal optimum.
Les forces de pression exercées entre la tête d'enregistrement et les échantillons et la distance tête-échantillon ont été sélectionnées de façon à avoir le meilleur enregistrement possible et une amplitude maximale du signal lors de la lecture.
Cette tête de lecture magnétorésistive a une sensibilité de l'ordre de 10 mV par Gauss et la résolution du capteur est 27µG. La largeur de la tête magnétorésistive est de 3 mm. La distance tête-échantillon est inférieure à 200 µm. L'intensité du courant dans la magnétorésistance est réglée à 10 mA.
Grâce à une unité d'exploitation, on lit un signal de sortie en millivolts (différence de tension résultant de la variation de la résistivité de la tête lors du passage de l'échantillon) qui traduit, en valeur absolue, les transitions de flux magnétique enregistrées.
