A RELATED APPLICATION

This application takes priority from provisional patent application U.S. No. 60/863246, filed October 27, 2006, which is fully incorporated herein by reference.

The technical FIELD TO WHICH the INVENTION RELATES

The present invention mainly relates to a secured document with dirt and/or moisture resistance, and to a method for producing such a protected document.

The prior art AND the INVENTION is

Optically changeable protective device, such as thin films, holograms, perforated sheets, microprism, photochromic materials and, more rarely, the film structure on the basis of microlenses (which are hereinafter collectively called OVD), recognized as valuable additives for saving documents, such as banknotes. These devices cover a lot of obvious optical effects when giving save the document properties of protection against forgery.

OVD-based microlenses is described in patent application U.S. No. 2005/0180020 A1 Steenblik et al. In the film material or the structure described in this link, used regular two-dimensional matrix feasibility lenses, designed to increase microimages, and in one variant embodiment includes (a) an optical separator; (b) regular periodic Planernoe the matrix of icons, located on one side of the optical splitter; and (c) regular periodic matrix of lenses located on the opposite surface of the optical splitter. The image projected this film structure, display numerous visual effects, including ortopedicheskoe movement.

OVD in the form of protective jumpers are fixed on one or both surfaces of the protected document (e.g. banknotes), whereas the OVD in the form of protective strips or filaments partially embedded in the document, so OVD can be seen through one or more clearly defined Windows on one or both surfaces of the document.

One of the main requirements for banknotes and other secure documents is that the document must be resistant to treatment. These documents must be durable (i.e. resistant to damage from bending, breaking and pollution) and resistant to moisture and chemical absorption. In addition, the seal that is applied to the document, should hold well, especially in harsh conditions, such as mechanical abrasion and accidental wash.

To make the notes and other secure documents greater resistance to the effects of treatment manufacturers and printers cover documents defined polymer varnishes and coatings. These varnishes and coatings, which consist libois of prepolymers, stitched ultraviolet (UV) radiation (100% solids), or mixtures of resins with different various solvents (the content of the rubber particles is in the range of 30-50 wt.%), serve for sealing the surface of the document, which increases its resistance to dirt and moisture. They are usually put on the final or almost final stage of manufacture of the document using standard technologies coating (for example, by coating, roller coating using an engraved cylinder, priming air scraper, coating the rolling roll, roll coating), and these surface coatings are usually known as post-printing varnishes. The density of the coating layer applied to each side surface of the document are in the range of from 0.5 grams per square meter (g/m2) to 5.0 g/m2.

Recently coating applied on the substrate used in the manufacture of these protected documents, either during manufacture or directly after their manufacture. These surface coatings, usually called pre-coating can be described as the binder resin, the water used to make the document resistance to moisture and contamination. Pre-coating may constitute or be 1-15% of the final m is ssy document.

Unfortunately, OVD in the protected documents subjected to one or both of these technologies in the prior art, at least in part, obscured, or, in other words, suffer adverse effects as a result of applying the overlying varnish or coating. How easily can understand the specialists in this field of technology, OVD put on a unique surface topography to achieve new and especially designed visual effects exposed machine verification. Drawing on these surface coatings and varnishes may darken, suppress, distort, or otherwise weaken the properties of these effects.

As the requirements for resistance to dirt and moisture increase, the number of pre-coating and/or post-printing varnishes, applied to the substrate, similarly increases. Thus, there is a compromise in the form of increased durability of the substrate in return for reduced performance and efficiency of some remedies. In addition, some types of varnishes contain light-diffusing additive to reduce the glossiness on the treated, lacquered documents. These additives can further reduce the effects of certain remedies.

Effort to prevent these destructive effects on optically variable effects generated by OVD, which some manufacturers (i) use a very small mass of the pre-coating or post-printing varnishes, which reduces the ability of the document to resist moisture and contamination, (ii) prevent the formation of a combination of pre-coating or post-printing varnishes with certain protective properties OVD, or (iii) block area on the surface of the document before applying the pre-coating or post-printing varnish, which leads to a substantial area of the surface of the document remain insecure, and overly complicates the application process.

The authors of the present invention, it was found that the optical effect of these OVD can be saved without compromising resistance to dirt and/or moisture by applying mud and/or water-resistant structure by size press or other similar device instead of using the standard technology of the coating. It was also revealed that the superimposed thin layers of fibers (e.g. fibers for paper production) and, thus, embedded in part of the protective devices in the protected documents containing window, giving the document dirt and/or moisture, thus, demonstrate increased durability.

The BEST WAY TO carry out the INVENTION

In accordance with the present invention it was found that dirt and/or moisture resistant materials and their application through a size press or other similar the th device, instead of using the standard technology of coating, does not obscure the optically variable effects generated by OVD, which is used on or in Bank notes and other security documents. It was also revealed that the durability of a thin fibrous layer located over the protective tapes or filaments embedded in a banknote with Windows or other protective documents increases with the application of mud and/or water resistant materials during manufacturing using a size press or other similar device.

The application of the present invention can improve the saving process, the method according to the invention provides more time-saving, clear way to ensure that dirt and/or moisture resistance of the protected document by removing the need in the processes of pre-coating and post-printing varnish and related capital investment in the equipment needed for the application of coatings and varnishes.

Although dirt and/or moisture resistant secure document according to the present invention is described herein primarily for use in the manufacture of banknotes, this invention is not limited. The protected document according to the invention can be used for the manufacture of many different items, including cheques, identity cards, lot is Anya tickets passports, stamps, certificates of ownership of shares, etc.

As noted above, the dirt and/or moisture resistant secure document according to the present invention contains at least one porous substrate having a thickness, and an effective amount of dirt and/or moisture resistant composition contained in the pores and on the opposite surfaces of the substrate (substrate), and dirt and/or moisture resistant composition is distributed, at least part of the thickness of the porous substrate (s).

Substrates suitable for use in the present invention, is a paper or numerophobia sheet materials having a porosity of from about 2 to about 100 milliliters per minute (ml/min), preferably from about 5 to about 50 ml/min Porosity is defined as the permeability determined according to ISO 5636-3 (15 September 1992). This test can be performed using tester L&W Bendtsen, made in AB Lorentzen &Wettre, Kista, Sweden.

These sheet materials, which are one - or multi-layer sheet materials can be made of various fibers, such as Manila hemp, cotton, linen, cellulose, and mixtures thereof. As is well known to experts in the field of machinery, cotton and blends of cotton/lanoiraude are preferred for banknotes, whereas cellulose is usually used in other security documents.

It is preferable that dirt and/or moisture resistant composition is provided for use in the present invention was prepared in the form of aqueous composition (e.g., dispersion)containing components of at least some of which are found in the pre-coating and post-printing lacquer according to the prior art. Among these components meet thermoplastic resin, such as resin, with binder on the basis of ester (for example, polyesters, polyethers), polyurethane resin, functionalityand polyurethane resin (for example, karboksilirovanie polyurethane resin), and copolymers (for example, urethaneacrylate resin, polyetherurethane resin, stirolakrilat resins) and mixtures thereof.

In addition to the above components, mud and/or water-resistant composition of the present invention can successfully contain other solvents, co-solvents or diluents, and additives, including (but not limited to) anti-microbial agents, catalysts, cross-linking agents (for example, silane cross-linking agents, antifoams, pigments (e.g. titanium dioxide), plasticizers, stabilizers, surfactants or smace the surrounding substances and viscosity modifier, provided that any such solvent, co-solvent, diluent or additive does not adversely affect the desired properties of the received protected document.

In a preferred variant embodiment of the dirt and/or moisture resistant composition is an aqueous dispersion of polymer, the average size of dispersed particles detected in the dispersion solution of the polymer is in the range of about 50-150 nanometers (nm), preferably about 70-140 nm).

In a more preferred variant of embodiment of mud and/or water-resistant aqueous dispersion of polymers contains solid particles of polyurethane resins, polyetherurethanes resins and/or urethaneacrylate resin (solid content of the resin particles in the dispersion is in the range of 30-50% of dry weight, preferably about 35-45% of dry weight). In another preferred variant of embodiment of mud and/or water-resistant aqueous dispersion of a polymer further comprises one or more pigments, such as pigment titanium dioxide, and, optionally, one or more cross-linking agents. An example of one such dispersion of polyurethane (without pigment and a crosslinking agent (agents)) is a product from the company Roymal, Inc., Newport, new Hampshire, USA, under the trade designation dispersion of polyurethane NOTEGUARD PRIMER.

Dirt and/or moisture resistant costumeshalloween by mixing component (components) with water to obtain an aqueous composition, having a total solids content in the range of about 10-40% of the dry weight (preferably about 15-30% of the dry mass, and more preferably about 20-25% of the dry weight), based on the total dry weight of the composition. the pH of the aqueous composition is 5.5 to 9.5, and preferably from 6.0 to 8.0.

It is preferable that the pigment was added to the composition before applying it on the porous substrate. The pigment is used to neutralize the effect of increasing the transparency of the resin and introduction into the porous substrate or the main sheet. Adding pigment to the composition immediately prior to its application to the main sheet eliminates the need for stabilizers to ensure homogeneity. It also provided for those structures that are necessary to make in order for different types of paper with different requirements, and even to control the homogeneity of the mixture during production of a particular grade of paper.

The method according to the invention to give a porous substrate dirt and/or moisture resistance includes (a) applying the above dirt and/or moisture resistant composition on the opposite surface of the porous substrate, (b) the penetration of dirt and/or moisture resistant composition in the pores of the substrate, and the composition thus penetrates and extends at least over part of the thickness of the substrate, and (c) deletion is the excess composition from the opposite surfaces of the substrate. Is preferable to pushing dirt and/or moisture resistant composition in the pores of the substrate and to remove excess composition from the opposite surfaces used in the size press or other similar device.

As is well known to experts in the art, after passing the "wet stage" production of paper machine fibrous fabric containing significant amounts of water, is directed into the nip (for example, the sequence of the heavy rotating cylinder), which is used to push water from the fiber fabric, with its subsequent compaction and reduced water content in it, usually up to about 70 wt.%.

After wringing the paper web is dried in the main drying zone of the paper machine. In the drying zone, which is usually the longest area of the paper machine, the hot air heated by steam cylinder is in contact with both sides of the web, virtually drying up the canvas due to the evaporation of the water level to about 5% by weight of the paper.

The dried fabric or substrate then glue surface on the sizing press. According to the present invention in the size press is used for pressing an effective amount (i.e. about 5-20%, preferably about 7.5-2.5% of dry matter, based on full dry weight of the substrate processed in the size press) dirt and/or moisture resistant composition in the internal voids of the substrate from both sides. The size press is also used to remove excess composition from the opposite surfaces of the substrate. Thus, the introduction and distribution of the composition, at least part of the thickness of the substrate.

The substrate processed in the size press, and then dried in the secondary zone of the paper machine drying until the moisture level of about 4-6%.

It is preferable that the porosity gerli (Gurley) received protected document was in the range of about 15000-300000 seconds, and more preferably in the range of about 40000-150000 seconds. Values of porosity Gurley determined using test method TAPPI No. T 460 om-06 (2006).

Dirt and/or moisture resistant formulation allows the creation of a secure document with maximum durability. Moreover, the suitability for printing a secure document will not be harmed, and in fact it can be improved.

For protected documents, which used one or more non-porous OVD, dirt and/or moisture resistant formulation provides the resulting protected document with maximum durability, without attenuation of the optical variations what's effects generated OVD. More specifically, in those areas of the substrate where there is non-porous OVD, OVD leads to the rejection of the composition from the surface of the OVD with increasing hydraulic pressure size press. On the surface OVD virtually no stock, which is now in the pores and on the opposite surfaces of the substrate.

In protected documents containing window, those parts of the protected document, which imposed on partially embedded protective devices exhibit improved durability in the form of a reduced tendency to tear and cracks.

As is well known to experts in the art, the protective tape or thread, partially integrated and partially located on the surface of the banknote or other protected document, usually called by the thread that is being implemented through a window is created. The built area of the filament is coated with a thin layer of paper, which is used to cover the threads and forms at least one window through which the thread comes out. This thin layer of paper may be the result of any technology used in the paper industry. As an example, the thread can be fed into the cylindrical listonline paper machine, cylindrical kruglosutochno paper machine, dlinnoyu paper machine or similar machine Izv the STN type, after passage of the suspension of paper fibers or paper pulp is deposited (or is subjected to selective deposition) on the security thread; or formed around it; or is expelled from the already formed paper web. As an additional example should indicate that to achieve partial implementation of threads in the paper, you can use the technology of lamination or wet lamination, as well as technology, which includes spraying fibrous suspensions on selected surfaces of the thread. The resulting overlay edges and jumpers not only cover part of the security threads, but also an integral, and not separately attached part of the paper structure.

One way of modeling the deterioration effects that protect the document or banknote subjected to the treatment described in the publication Bartz WJ. and Crane T.T. "The Circulation Simulator Method for Evaluating Bank Note and Optical Feature Durability", SPIE, so 6075, San Jose, California, January 2006 this publication describes the test method developed by Crane & Co., Inc., which simulates the wear observed in the current banknotes currently in circulation, i.e. pollution, wrinkling, cracking, formation of dangling edges and creasing. In the described test method, which is hereinafter referred to as "modeling method, used in isulan cleaning drum, set on shelling machine. Samples of banknotes weighed at each corner and is tested for durability in the drum in an environment shot glass, metal discs and a mixture of technical dirt for three 30-minute cycles that involve the physical destruction of samples of the banknote. Durability graded on how well banknote retains its original optical and physical properties after it has been subjected to conditions modeling method reference.

Banknotes containing security threads, which were subjected to the described conditions modeling method of treatment may in some cases to demonstrate the fragility of a sheet of thin paper, which covers the security thread. Examples of this fragility are cracking or rupture of the sheet of paper. One observation that was made about the bills created by the Windows containing non-porous optically variable security threads, with the effect of the microlenses, which were obtained in accordance with the present invention is that the layer of thin paper, which covers the security thread, better resists the effects of the destruction caused by modeling treatment. This improved strength or increased durable to u is ity visually noticeable, and its proof is a thin layer of paper remaining intact and that there are no gaps and cracks.

The second sections include the second protection sign which is provided with similar appearance in each second section but differs from the first protection sign. It is not visible in the reflected light when one looks at the first surface of base plate. On the contrary, the second protection sign is visible in radiographic light if one looks at the first surface of base plate.

EFFECT: designing of base plate with different protection signs subject to identifying under different observation conditions.

SUBSTANCE: method pertains to manufacturing of fraud-proof paper used for manufacturing of fraud-proof polygraphic products. According to the first variant of the method for manufacturing fraud-proof paper, paper linen with more than 2 mm width protective tape is formed, the said tape being inset into the aforesaid linen at its formation on a grid cylinder. Note that a protective tape is introduced into the mass so as to form, prior to its contact with the cylinder, a mould fibrous layer, excluding the areas on the cylinder surface where no fibrous layer is formed due to the absence of filtering capacity. The protective tape is placed on the cylinder in such a manner that part of its surface matches with cylinder elements on which formation of the layer does not occur, zones of access being formed, i.e. windows from the grid side of paper. Areas on the cylinder surface with absence of filtering capacity are created either by closing grid with filigrane, or by filling the grid with waterproof material, or by furnishing the grid with through holes. From the side opposite to that of the grid, the protective tape is fully or partially open, through windows being formed in places of windows matching from the grid side and full or partial exit of the protective tape from the opposite side of paper. According to the second, third and fourth versions, paper linen with more than 2 mm width protective tape is formed, exit of the protective tape being provided on both sides of paper linen to produce the effect of a through window.

EFFECT: better fraud-proofness of paper.

The given solution allows for increasing operation reliability and durability of monetary notes as well as for lowering expenses for monetary circulation maintenance.

EFFECT: increased operation reliability and durability of monetary notes.

FIELD: textile, paper.

SUBSTANCE: method refers to manufacture of bond paper protected from forgery, using polymer thread with figured edge as a protective element. The thread consists of central core and side elements shaped as wings. The polymer metallised thread with figured edge is implemented into the paper during the process of its manufacturing in the mold of the papermaking machine. Then follows dehumidification of the product along with layer forming and its pressurising. The thread is strained during implementing into paper. The thread strain provides creation of fibers on the surface of central core in the wings area. This provides voluminosity of the protective element.

EFFECT: bond paper protection enhancement.
