Abstract

A security paper (1) in the form of a laminate comprises at least two laminate layers (2, 3) with at least one paste layer (4) therebetween. At least one of the layers (2, 3, 4) is of a colour which differs from the adjacent layers. The strength of the bonding between the paste layer (4) and adjacent laminate layers (2, 3) is greater than the inner strength of the layers (2, 3, 4). Furthermore, the paste or adhesive in the paste layer (4) is of the curing or setting type.

Description

10 15 20 25 30 35 513 878 2 är antingen dyra i tillverkning eller svåra att kontrollera manuellt utan sär- skild utrustning eller, i värsta fall, båda delar. i Det förekommer att man laminerar samman två eller flera skikt av papper, metall eller plast. Genom noggrant materialval och genom förfarandet vid tillverkningsprocessen kan egenskaperna hos laminatet styras. 10 15 20 25 30 35 513 878 2 are either expensive to manufacture or difficult to control manually without special separate equipment or, in the worst case, both. in It happens that you laminate together two or more layers of paper, metal or plastic. Through careful material selection and through the procedure at the manufacturing process, the properties of the laminate can be controlled.

Den europeiska patentansökningen med publ.nr. 0 453 131 visar ett säker- hetspapper som är uppbyggt i två lager med ett klisterskikt däremellan. På insidan av det ena eller båda papperen är tryckt äkthetsindikatorer. De op- tiska egenskaperna hos klistret mellan papperen är sådana att äkthetsindika- torema är praktiskt taget osynliga i reflekterat ljus, men syns i transmitterat ljus. Det är också möjligt att utforma äkthetsindikatom så att den endast kan upptäckas med icke synligt ljus eller magnetiska hjälpmedel. Nackdelarna med ett papper enligt denna patentansökan är att det antingen krävs goda ljusförhållanden för att upptäcka en äkthetsindikator som är synlig i trans- mitterat ljus, eller också särskilda tekniska hjälpmedel för att upptäcka äkt- hetsindikatorer som endast kan upptäckas med hjälp av magnetism eller icke synligt ljus.The European patent application with publ.nr. 0 453 131 shows a safety hot paper that is built up in two layers with an adhesive layer in between. On inside one or both papers are printed authenticity indicators. The op- The properties of the adhesive between the papers are such that the authenticity the tores are virtually invisible in reflected light, but visible in transmitted light. It is also possible to design the authenticity indicator so that it can only detected with invisible light or magnetic aids. The disadvantages with a paper according to this patent application is that either good is required lighting conditions to detect an authenticity indicator visible in the trans- emitted light, or also special technical aids for detecting health indicators that can only be detected with the help of magnetism or not Visible light.

EP 0 491 O99-A1 visar en säkerhetstape som är uppbyggd av flera lager material, nämligen en plastfilm, två lager häftmaterial och ett skyddsskikt som dras bort när tapen skall tas i bruk. Det lager häftmaterial som ligger närmast plastfilmen fäster bäst vid denna film och är dessutom färgat. Mellan plastfilmen och det färgade häftmaterialet är anordnat ett icke kontinuerligt mönster av ett genomskinligt barriännaterial. Det färgade häftmaterialet fäst- er sämre vid barriärrnaterialet än vid plastfilmen. Häftmaterialet som är när- mast det underlag som tapen är fäst vid, har en starkt vidhäftande förmåga.EP 0 491 O99-A1 shows a safety tape that is made up of lager your bearings material, namely a plastic glue, two layers of adhesive material and a protective layer which is removed when the tape is to be used. The layer of adhesive material that lies the closest plastic film attaches best to this film and is also colored. Between the plastic film and the colored adhesive material are arranged non-continuously pattern of a transparent barrier material. The colored adhesive material is worse with the barrier material than with the plastic film. The adhesive material that is mast the substrate to which the tape is attached has a strong adhesive ability.

När tapen rivs bort från underlaget framträder ett mönster eftersom det färg- ade häftrnaterialet följer med plastfilrnen utom på de ställen som är försedda med barriärmaterialet. Uppfinningen är i första hand avsedd att skapa förslut- ningar som inte kan öppnas utan att det märks. Man kan även tänka sig att tapen används för äkthetskontroll, exempelvis så att varje äkta dokument för- ses med ett stycke av tapen, som inte kan flyttas till en förfalskning. En stor nackdel är att en äkthetskontroll innebär att tapens äkthet kontrolleras genom att den dras bort så att det karaktäristiska mönstret framträder. Detta för- farande medför att ett äkta dokument fiamstår som en förfalskning vid en andra kontroll. Det förekommer ju, exempelvis under längre tågresor, att bil- jetter kontrolleras mer än en gång. lO 15 20 25 30 35 513 878 3 En annan nackdel med uppfinningen enligt EP O 491 099-Al är att det är svårt att i en rationell tillverkningsprocess förse plastfilmen med barriännate- rial i ett icke kontinuerligt mönster.When the tape is torn off the substrate, a pattern emerges because the color The adhesive material comes with the plastic files except in the places provided with the barrier material. The invention is primarily intended to create closures. which cannot be opened without being noticed. One can even imagine that the tape is used for authentication, for example so that each genuine document is seen with a piece of tape, which can not be moved to a forgery. A big disadvantage is that an authenticity check means that the authenticity of the tape is checked by that it is pulled away so that the characteristic pattern emerges. This This means that a genuine document som resembles a forgery at a second control. It happens, for example during longer train journeys, that cars jets are checked more than once. lO 15 20 25 30 35 513 878 3 Another disadvantage of the invention according to EP 0 491 099-A1 is that it is it is difficult in a rational manufacturing process to provide the plastic film with barrier rial in a non-continuous pattern.

PROBLEMSTÄLLNING Den föreliggande uppfinningen har till ändamål att tillhandahålla ett säker- hetspapper vars äkthet enkelt kan kontrolleras utan tillgång till särskilda tekniska hjälpmedel. Frarnställningssättet skall också vara kostnadseffektivt, men inte tillgängligt för gemene man.TROUBLESHOOTING The present invention has for its object to provide a safe papers whose authenticity can be easily verified without access to special technical aids. The method of production must also be cost-effective, but not available to the common man.

PRQBLEMLÖSNING Den till grund for uppfinningen liggande målsättningen uppnås om det inled- ningsvis nämnda säkerhetspapperet kännetecknas därav, att styrkan hos vid- häftningen mellan respektive klisterskikt och de närliggande laminatskikten är större än skiktens inre styrka.PRQBLEM SOLUTION The objective underlying the invention is achieved if the initial said security paper is characterized in that the strength of the the adhesion between the respective adhesive layers and the adjacent laminate layers is greater than the inner strength of the layers.

Ytterligare fördelar uppnås enligt uppfinningen om uppfmningsföremålet även ges ett eller flera av särdragen enligt patentkraven 2-6.Additional advantages are achieved according to the invention on the object of the invention one or more of the features according to claims 2-6 are also provided.

SAMMANSTÄLLNING ÖVER RITNINGSFIGURER Uppfinningen skall nu beskrivas närrnre under hänvisning till bifogade rit- ningar. På dessa visar: fig l ett tvärsnitt genom ett sönderrivet säkerhetspapper enligt uppfin- ningen vari brottet skett på ett forsta sätt; fig 2 en vy motsvarande fig 1, vari brottet skett på ett andra sätt; fig 3 säkerhetspapperet enligt fig l sett rakt ovanifrån när ett höm bort- rivits; fig 4 ett tvärsnitt genom säkerhetspapperet enligt en andra utfóringsforrn; och fig 5 som visar en schematisk vy över framställningen av ett laminat. 10 15 20 25 30 35 515 878 FÖREDRAGEN UTFÖRINGSFORM I fig l visas ett säkerhetspapper 1 enligt uppfinningen. Säkerhetspapperet 1 innefattar två laminatskikt 2, 3 och ett däremellan beläget klisterskikt 4.COMPILATION OF DRAWING FIGURES The invention will now be described in more detail with reference to the accompanying drawings. nings. On these shows: Fig. 1 is a cross-section through a torn security paper according to the invention the crime in which the crime took place in a first way; fi g 2 a view corresponding to fi g 1, in which the crime took place in a second way; fi g 3 the safety paper according to fi g l seen directly from above when a corner is removed. rivits; 4 g 4 a cross-section through the security paper according to a second embodiment; and 5 g 5 which shows a schematic view of the production of a laminate. 10 15 20 25 30 35 515 878 PREFERRED EMBODIMENT Fig. 1 shows a security paper 1 according to the invention. The security paper 1 comprises two laminate layers 2, 3 and an adhesive layer 4 located therebetween.

Tj ockleken hos laminatskikten är betydligt större än tj ockleken av klister- skiktet. I figuren visas även brottytan 5, som uppstår då papperet rivs sönder.The thickness of the laminate layers is significantly greater than the thickness of the adhesive. the layer. The figure also shows the fracture surface 5, which occurs when the paper is torn.

Gränsytoma mellan skikten 2 och 4 respektive mellan skikten 3 och 4 har blottlagts. Detta medför att papperet och den avrivna kanten får ett utseende som visas schematiskt i fig 3. För att åstadkomma den önskade effekten, nämligen en brottyta med ett utseende enligt fig 3, där det färgade klistret tydligt syns i brottytan, måste material i såväl laminatskikten som i klister- skiktet väljas med omsorg. Laminatskikten är exempelvis plast, papper eller metall av en sådan tjocklek och hållfasthet att det är möjligt att riva sönder det färdiga laminatet utan större svårigheter. Det färdiga laminatet måste dock tåla en viss nonnal hantering utan att gå sönder.The interfaces between layers 2 and 4 and between layers 3 and 4, respectively exposed. This gives the paper and the torn edge a look shown schematically in Fig. 3. To achieve the desired effect, namely a fracture surface with an appearance according to fi g 3, where the colored adhesive clearly visible in the fracture surface, materials in both the laminate layers and the adhesive the layer is chosen with care. The laminate layers are, for example, plastic, paper or metal of such thickness and strength that it is possible to tear it apart the finished laminate without major difficulties. The finished laminate must however, withstand a certain nonnal handling without breaking.

Klisterskiktet består lämpligen av ett härdande klister. I många fall kan två- komponentsklistren polyuretan eller epoxiklister användas.The adhesive layer suitably consists of a hardening adhesive. In many cases, two- the component adhesives polyurethane or epoxy adhesives are used.

För att erhålla den önskade brottytan, måste den inre hållfastheten i respek- tive skikt balanseras mot hållfastheten hos fogarna mellan skikten.In order to obtain the desired fracture surface, the internal strength in the respective tive layers are balanced against the strength of the joints between the layers.

Fogen mellan klisterskiktet 4 och laminatskikten 2, 3 måste vara starkare än skiktens inre hållfasthet, så att det färgade klisterskiktet med säkerhet blott- läggs vid sönderrivning av papperet 1. Med andra ord måste hållfastheten vinkelrätt mot papperets plan vara mindre än hållfastheten hos fogen mellan klistret och laminatskiktet. Klistret 4 tränger in ett litet stycke i laminatskik- ten 2 och 3, under förutsättning att dessa är någorlunda porösa. I de, vanligt förekommande, fall där åtminstone ett av de laminatskikt 2, 3 som omger klisterskiktet 4 består av papper, leder detta till att pappersfibrerna bildar en armering i klisterskiktet. Airneringen ger en ökad hållfasthet åt fogen mellan papper och klister. I sådana fall brister laminatskiktet 2, 3 vid gränsen mellan det område som är opåverkat av klistret och det område i vilket klistret har trängt in. Denna brottyp visas i fig 1, medan fig 2 visar exempel på ett brott som skett i klisterskiktet, snarare än i fogarna. Étt viktigt drag i uppfinningen är att klistret 4 år härdande, så att det efter lamineringen varken kan lösas upp eller smältas. Detta är väsentligt för att 10 15 20 25 30 513 878 5 förhindra utbyte av något av laminatskikten, och på så sätt möjliggöra en för- falskiiing.The joint between the adhesive layer 4 and the laminate layers 2, 3 must be stronger than the internal strength of the layers, so that the colored adhesive layer is laid when tearing the paper 1. In other words, the strength must perpendicular to the plane of the paper be less than the strength of the joint between the adhesive and the laminate layer. The adhesive 4 penetrates a small piece into the laminate layer. 2 and 3, provided that they are reasonably porous. In those, common occur, cases where at least one of the surrounding laminate layers 2, 3 the adhesive layer 4 consists of paper, this leads to the paper edges forming one reinforcement in the adhesive layer. The ventilation gives an increased strength to the joint between paper and glue. In such cases the laminate layer 2, 3 breaks at the boundary between the area that is unaffected by the adhesive and the area in which the adhesive has penetrated. This type of crime is shown in Fig. 1, while Fig. 2 shows examples of a crime which occurred in the adhesive layer, rather than in the joints. An important feature of the invention is that the adhesive cures for 4 years, so that after the lamination can neither be dissolved nor melted. This is essential for that 10 15 20 25 30 513 878 5 prevent the replacement of any of the laminate layers, thus enabling a falskiiing.

Lamineringen av säkerhetspapperet 1 föregår enligt den teknik, som visas i fig 5. Ett laminatskikt, den s k ädelfilmen 8, leds från rullen 9 genom vals- paret 10, 1 1. Valsen ll beläggs i karet 12 med klister, vilket påförs även filmen 8, då det passerar genom valsparet 10, l 1. Den med klister belagda ädelfilmen leds därefter en kortare eller längre sträcka, varunder eventuellt en viss torkning kan ske, till det s k lamineríngsnypet mellan valsarna 13, 14. I detta steg lamineras den belagda ädelfilmen ihop med ytterligare ett lamine- ringsskikt 15, som avleds från rullen 16. Efter lamineringen har larninatet l bildats, och detta leds till rullen 17. Utmärkande för papperet enligt uppfin- ningen är att ett färgpigment blandats i klistret. Om ett tvåkomponentsklister används, blandas färgpigmentet lämpligen i den ena av de två komponenter som ingår i klistret.The lamination of the security paper 1 proceeds according to the technique shown in Fig. 5. A laminate layer, the so-called boiler film 8, is guided from the roll 9 through the roll pair 10, 1 1. The roller ll is coated in the tub 12 with adhesive, which is also applied the film 8, as it passes through the pair of rollers 10, 1 1. The one coated with adhesive the noble film is then led a shorter or longer distance, during which possibly one some drying can take place, to the so-called lamination pinch between the rollers 13, 14. I In this step, the coated noble film is laminated together with another laminated film. ring layer 15, which is diverted from the roll 16. After lamination, the larnate 1 formed, and this is led to the roll 17. Characteristic of the paper according to the invention is that a color pigment is mixed into the adhesive. About a two-component adhesive used, the color pigment is suitably mixed in one of the two components included in the adhesive.

ALTERNATIVA UTFÖRINGSFORMER I fig 4 visas en altemativ utföringsform av uppfinningen. Larninatet 1 har här försetts med ytterligare ett laminatskikt 7, som förenats med de övriga lami- natskikten med hjälp av klisterskiktet 6. Klisterskikten 4 och 6 kan ha samma färg, men kan även ha olika färg för att ge en särpräglad brottyta vid sönder- rivningen. Laminatskikten 2, 3, 7 kan ha inbördes likadan färg, men även färger som skiljer sig från varandra. I allmänhet är man dock intresserad av att färgerna och tjockleken på laminatskikten 2, 3, 7 respektive klisterskikten 4, 6 väljs så att klisterskikten 4, 6 inte lyser igenom de yttre laminatskikten 2, 7.ALTERNATIVE EMBODIMENTS Fig. 4 shows an alternative embodiment of the invention. Larninatet 1 has here provided with an additional laminate layer 7, which is joined to the other laminates the wet layers using the adhesive layer 6. The adhesive layers 4 and 6 may have the same color, but may also have different colors to give a distinctive breaking surface in the demolition. The laminate layers 2, 3, 7 can have the same color with each other, but also colors that differ from each other. In general, however, one is interested in that the colors and thickness of the laminate layers 2, 3, 7 and the adhesive layers, respectively 4, 6 is selected so that the adhesive layers 4, 6 do not shine through the outer laminate layers 2, 7.

Analogt är det möjligt att förse laminatet 1 med ytterligare klisterskikt och laminatskikt. Laminatskikten är ofta papper, men kan även vara utförda av annat material, såsom plast eller metallfolie. I vissa fall kan man även tänka sig att något eller några av klisterskikten utgörs av en plastfolie, som even- tuellt kan vara färgad.Analogously, it is possible to provide the laminate 1 with additional adhesive layers and laminate layer. The laminate layers are often paper, but can also be made of other material, such as plastic or metal foil. In some cases, you can even think that one or more of the adhesive layers consists of a plastic foil, which may be colored.
