Varnostni ali okrasni papir, ki vsebuje ploščiceSafety or decorative paper containing tiles
Izum obravnava liste, ki obsegajo ploščice in se jih uporablja predvsem za izdelovanje varnostnih dokumentov ali okrasnih listov. Obravna tudi ploščice.The invention relates to sheets comprising tiles and is used primarily for the production of security documents or decorative sheets. It also deals with tiles.
Overitev varnostnega dokumenta (bankovcev, potnih listov, osebnih izkaznic ipd.) se lahko izvaja zahvaljujoč enemu ali več varnostnih elementov, kot so vodni žigi, varnostne niti ali ploščice. Nekateri izmed teh elementov, predvsem kadar nudijo optične efekte površine, prav tako sodelujejo pri zaščiti dokumenta pred repruduciranjem s pomočjo fotokopiranja ali izdelovanjem faksimila.The authentication of a security document (banknotes, passports, identity cards, etc.) can be done thanks to one or more security features, such as watermarks, security threads, or tiles. Some of these elements, especially when offering optical surface effects, also work to protect the document from reproduction by photocopying or facsimile production.
Da bi se okrasne liste izvedlo uporabne v različnih področjih, npr. kot embalažo ali stenske opaže, se včasih uporablja ploščice, ki imajo prednostno površinske optične efekte.In order to make decorative leaves useful in different fields, e.g. as packaging or wall paneling, tiles are used which preferably have surface optical effects.
Ploščice so papirni trakovi, ki imajo različne oblike, npr. okrogle, heksgonalne. Na splošno so izvedene z obrezovanjem plastičnega filma ali lista papirja. Da bi se izdelalo varnostne papirje ali papirje za bankovce, ki vsebujejo ploščice, se le-te uvede v vodno disperzijo, ki vsebuje celulozna vlakna, eventuelno sintetična vlakna, in druge aditive, ki se jih sedaj uporablja v raznih postopkih v papirnicah. Ko se odcedi |C 1 1 1 2 9 ά vodno suspenzijo na situ papirniškega stroja, ki je lahko okroglo ali Fourdrinieijevo, se določeno število ploščic namesti na površini papirnega lista, ki se ga tako stvori, in se nato ta list osuši.Tiles are paper strips that have different shapes, e.g. round, hexagonal. They are generally made by trimming a plastic film or sheet of paper. In order to produce security papers or banknote papers containing tiles, they are introduced into an aqueous dispersion containing cellulose fibers, possibly synthetic fibers, and other additives, which are now used in various processes in paper mills. After draining | C 1 1 1 2 9 ά the aqueous suspension on a paper machine situa- tion, which may be round or Fourdrinie's, a certain number of tiles are placed on the surface of the paper sheet thus created and then dried.
Kot je bilo zgoraj omenjeno, je prednostno, da ploščice in torej material, v katerem se jih odreže, zagotavljajo površinske optične efekte, kot so mavričnost ali dihroizem, fluorescenčnost, odbojnost ah polarizacija svetlobe. Poznano je npr., kako se izvede mavrične filme, s tem da se hkrati ekstrudira več plasti polimerov, ki imajo približno enake lomne količnike.As mentioned above, it is preferred that the tiles, and therefore the material in which they are cut, provide surface optical effects such as rainbow or dichroism, fluorescence, reflectance and polarization of light. For example, it is known how rainbow films are made by extruding multiple layers of polymers having approximately the same refractive index.
Da bi se lahko opazilo površinski optični efekt, morajo biti te ploščice na površini papiga.In order to be able to see the surface optical effect, these tiles must be on the surface of the parrot.
Prvi problem, ki se postavlja, je v tem, da je zelo težko, ko so te ploščice plastične, npr. iz poliestra, dispergirati jih v vodi, omočljivost plastičnih filmov je zelo majhna, in jih torej dodati ob oblikovanju lista papirja.The first problem that arises is that it is very difficult when these tiles are plastic, e.g. made of polyester, dispersed in water, the wettability of plastic films is very small, and therefore added when forming a sheet of paper.
Drug problem je povezan z njihovo šibko afiniteto do celuloze in/ali veziv, ki se jih uporablja za površinsko obdelavo papirja. Ploščice torej težijo k temu, da se odlepijo od površine papirja, ko se tiska in/ali ko se rokuje s papirjem.Another problem is related to their weak affinity for the pulp and / or binders used for surface treatment of the paper. Tiles therefore tend to peel away from the surface of the paper when printed and / or when handling paper.
V patentni prijavi EP-A 342 929 se je poskušalo razrešiti te probleme, s tem da se je nalepilo folijo iz celuloznih vlaken na plastičen film s pomočjo adheziva in to pred obrezovanjem ploščic. Vendar pa je ena izmed pomanjkljivosti v tem, da pri delu tako izdelanih ploščic stran, ki je sestavljena iz vlaknate folije, dospe na površino papirja in se torej ne opazi površinskega optičnega efekta plastičnega filma. Razen tega te ploščice, če so slabo razporejene, težijo k temu, da se odlepijo od površine papirja.EP-A 342 929 sought to address these issues by gluing a cellulose fiber film to a plastic film using an adhesive prior to tiling. However, one of the drawbacks is that when the tiles are made in this way, the page, which consists of fibrous film, reaches the surface of the paper and therefore does not notice the surface optical effect of the plastic film. In addition, when poorly spaced, these tiles tend to peel off the surface of the paper.
Predlaga se izum za razrešitev teh problemov.An invention is proposed to solve these problems.
Eden izmed ciljev izuma je v tem, da se izdela list, ki obsega ploščice, ki so izdelane izhajajoč iz plastičnega filma in se jih namesti na površino lista, ki pa se ne iztrgajo ob pritiskanju ali ob kakršnemkoli drugem obdelovanju površine lista ali ob rokovanju z listom.One object of the invention is to provide a sheet comprising tiles made from a plastic film and placed on the surface of the sheet, which is not torn off when pressed or otherwise treated by the surface of the sheet or when handled. listom.
Druga naloga je v tem, da se izdela list, ki obsega ploščice, ki zagotavljajo površinskeAnother task is to produce a sheet comprising tiles that provide surface
L 1 1 1 2 92 optične efekte.L 1 1 1 2 92 optical effects.
Nadaljnja naloga je v tem, da se izdela list, ki obsega ploščice, ki se jih lahko dispergira v vodni masi.A further task is to produce a sheet comprising tiles that can be dispersed in water mass.
Naloge izuma so rešene s tem, da se uporabi ploščice, ki se jih izdela izhajajoč iz plastičnega filma, in da se prevleče po vsaj eni izmed njihovih strani s sestavkom, ki vsebuje vsaj en agent, ki izboljša omočljivost.The objects of the invention are solved by the use of tiles made from a plastic film and coated on at least one of their sides with a composition containing at least one wetting enhancing agent.
Tako se z izumom stvori list, ki obsega ploščice, ki so stvorjene izhajajoč iz plastičnega filma, ki je označen s tem, da so ploščice prevlečene vsaj na eni izmed svojih stranic s sestavkom, ki obsega vsaj en agent, ki izboljšuje omočljivost.Thus, the invention provides a sheet comprising tiles formed from a plastic film, characterized in that the tiles are coated on at least one of their sides with a composition comprising at least one wetting enhancer.
Pri izumu pa se lahko uporablja prav posebno ploščice, ki so prevlečene na obeh straneh.In the invention, however, special tiles coated on both sides can be used.
Prednostno ima to sredstvo značilnost zalivanja pod vplivom toplote. Ta značilnost izboljša obnašanje ploščic na površini lista. Ta značilnost se doseže med izdelovanjem lista na papirniškem stroju v toku sušenja lista.Preferably, this agent has the character of watering under the influence of heat. This feature improves the behavior of the tiles on the leaf surface. This feature is achieved when making a sheet on a paper machine during the drying process of the sheet.
Sredstvo, ki izboljša omočljivost, je prednostno vinilni kopolimer in prav posebej vinil acetata - vinil klorida in vinil etilena.The wettability enhancer is preferably a vinyl copolymer and especially vinyl acetate - vinyl chloride and vinyl ethylene.
Sestavek prevleke je lahko v vodnem mediju ali pa v mediju topila. V tem zadnjem primeru se bo izbralo topilo, ki ne najeda plastike, ki je uporabljena za izdelovanje ploščic, in ne poslabšuje površinskega optičnega efekta, če le-ta obstoja.The coating composition may be in an aqueous medium or in a solvent medium. In this latter case, a solvent that does not corrode the plastic used to make the tiles will be selected and will not impair the surface optical effect, if any.
Vendar pa se zaradi dobro poznanih problemov, ki so povezani s higieno in z varnostjo, prednostno uporablja vodni sestavek. Sestavek je prednostno premaz v vodnem mediju.However, due to the well-known problems associated with hygiene and safety, the aqueous composition is preferred. The composition is preferably a coating in aqueous medium.
Sestavek se nanaša na površino filma s poljubno gaučo ali sredstvom za tiskanje.The composition refers to the surface of the film with any gauze or printing medium.
Količina sredstva za izboljšanje omočljivosti, ki se ga je naneslo, izražena v suhi masi je med 0,5 in 3 g/m2 na eno stran.The amount of wetting agent applied, expressed in dry weight, is between 0.5 and 3 g / m 2 to one side.
Prednostno se uporablja ploščice, ki imajo površinski optični efekt, pri čemer jePreferably, tiles having a surface optical effect are used, whereby
1112 92 lahko ta efekt eventuelno različen za vsako stran.1112 92 this effect may be different for each page.
Z izumom se tako stvori list, kije značilen po tem, da ploščiče izvajajo mavričnost ali dihroizem, fluorescenco, odboj svetlobe, polarizacijo svetlobe ali kak drug površinski optičen efekt. Ta optičen efekt lahko izvira od filma, izhajajoč od katerega sta napr. izvedeni mavričnost večplastnega filma ali fluorescenca filma, ki je izdatno obdan s fluorescentnimi pigmenti. Ta učinek lahko tudi izhaja iz obdelave površine filma, pri čemer je ta obdelava lahko izvedena hkrati, ko se preoblači film s sestavkom, ki vsebuje sredstvo za izboljšanje omočljivosti.The invention thus creates a sheet, characterized in that the plates exert rainbow or dichroism, fluorescence, light reflection, polarization of light or any other surface optical effect. This optical effect may originate from a film, e.g. derived rainbow of a multilayer film or fluorescence of a film richly surrounded by fluorescent pigments. This effect may also result from the treatment of the surface of the film, whereby this treatment can be performed at the same time that the film is coated with a composition containing a wetting agent.
Ploščice se doda listu med izdelovanjem na papirniškem stroju po postopkih, ki so znani strokovnjaku s področja.The tiles are added to the sheet during manufacturing on a paper machine according to procedures known to one of skill in the art.
List se lahko izdela z organskimi vlakni naravnega porekla, kot so celulozna vlakna; lahko pa vsebuje tudi sintetična in/ali mineralna vlakna.The sheet may be made with organic fibers of natural origin, such as cellulose fibers; it may also contain synthetic and / or mineral fibers.
Listje eventuelno lahko večplasten list.The leaves may eventually be a layered leaf.
Izum obravnava tudi varnostne dokumente (bankovce, potne liste, vrednostne papiije ipd.), ki se jih dobi izhajajoč iz omenjenih listov, ki vsebujejo ploščice.The invention also relates to security documents (banknotes, passports, securities, etc.) obtained from the said sheets containing the plates.
Z izumom se tudi tvori okrasne liste, npr. za embalažo, stenske opaže ipd., ki se jih dobi izhajajoč iz omenjenih listov, ki vsebujejo ploščice.The invention also forms decorative leaves, e.g. for packaging, wall coverings and the like, obtained from the aforesaid sheets containing tiles.
Po izumu se tudi tvori ploščice, ki se jih dobi z obrezovanjem plastičnega filma, ki je na vsaj eni svoji strani prevlečen s sestavkom, ki vsebuje vsaj enega izmed sredstev za izboljšanje omočljivosti.The invention also provides tiles obtained by trimming a plastic film coated on at least one side with a composition containing at least one of the wettability enhancers.
To sredstvo ima lahko značilnost zalivanja pod vplivom toplote in prednostno ima ploščica površinski optični efekt.This agent may have a watering characteristic under the influence of heat and preferably have a surface optical effect.
Izum bo bolje pojasnjen z naslednjim izvedbenim primerom, ki pa ni omejujoč.The invention will be better explained by the following non-limiting embodiment.

IZVEDBENI PRIMEREXECUTIVE EXAMPLE
Plastičen večplasten mavričast film, ki je poznan pod komercialnim imenom MEARL, se namaže z vodnim namazom vinil acetata - vinil klorida in vinil etilena, ki je komercialno poznan pod imenom VINAMUL.The plastic multilayer rainbow film, known commercially as MEARL, is coated with an aqueous coating of vinyl acetate - vinyl chloride and vinyl ethylene, commercially known as VINAMUL.
Količina premaza, ki se odloži na vsako stran je okoli 2 g/m2 suhe mase. Tako prevlečen film se nareže v ploščice heksagonalne oblike. Ugotovi se, da se je omočljivost ploščice izboljšala, s tem da se meri mejni kot kapljice vode na filmu.The amount of coating deposited on each side is about 2 g / m 2 of dry mass. The film thus coated is cut into tiles of hexagonal shape. It is found that the wettability of the tile has improved by measuring the boundary angle of water droplets on the film.
Pred obdelavo filma je ta kot 85°; po obdelavi je 4°. Omočljivost se je torej znatno povečala.Before film processing, this angle is 85 °; after treatment is 4 °. The wettability therefore increased significantly.
Te ploščice se vdela na površini lista papirja po postopku, ki je poznan strokovnjaku s področja.These tiles are embedded on the surface of a sheet of paper in a manner known to one of skill in the art.
Dobljen list se tiska s pomočjo ofseta. Ugotovi se, da se med tiskanjem ne iztrga ploščic iz površine papiga. Tako se ne odtrgajo ob rokovanju z listom.The resulting sheet is printed using offset. It is found that the tile does not tear from the parrot surface during printing. Thus, they are not torn off when handling the leaf.
Obnašanje ploščic na površini papiga je prav tako izboljšano zaradi premaza, ki ima značilnost zalivanja pod vplivom toplote, ki se razvije med sušenjem lista.The behavior of the tiles on the surface of the parrot is also enhanced by the coating, which has the characteristic of watering under the influence of heat, which develops during drying of the leaf.
