Description of the invention (1) The present invention relates to paper used for security documents. In more detail, there are SS documents that will be subject to a considerable amount of processing such as banknotes and driver's licenses. It is important that these security documents are durable; in other words, they should be able to protect against tearing, folding damage and dirt. During the processing, the moisture and chemical products absorbed by these documents will cause the deterioration of material properties. Advantageously, the substances of this kind of security documents are anti-absorption. Of course, the primary need for such documents is that the printing applied to the material should adhere well, especially in serious situations involving mechanical wear or accidental cleaning. Such security documents related to the present invention include one or more visible security features to prevent or deter counterfeiting. Available security features include watermarks and security threads stored on paper. The security thread can be arranged entirely in the paper or exist in a so-called window between the areas, where the thread exists between the surfaces of the paper such as bank notes of Bank of England sequence E. Normally, in terms of security documents • Materials must be of good quality to ensure good relief work • Relief made with the known Intaglio printing, and ensure good durability.

It is also known that in general * various polyurethane compositions M can be used on a wide range of materials to provide protective coatings; in such applications * polyurethane has been used as wood or other Material paint. At the same time, it is known from the European Patent EP-B-189945 to use a polyurethane composition as a glue for paper. When the coated paint containing pigments is used to make protective papers • As in PCT application No. W091 / 12372, these pigments usually have the general Chinese national standard (CNS) Α4 specification (210X 297) Mm> A7 B7 printed by the staff swilling cooperative of the Central Bureau of Economic Development of the Ministry of Economic Affairs 5. Description of the invention (2) The advantages of good ink combination microporosity or roughness. However, the existence of pigments will cause serious shortcomings> ; For example, the security characteristics of materials such as watermarks or window lines are somewhat obscure. Due to the presence of pigments, it causes the adhesive to stick less firmly to the material in specific areas, making the coating containing pigments naturally weaker Generally, when using a pigment-containing coating composition, the coating step is performed after the paper is made | and this involves the disadvantage that the paper must be dried before applying the coating. The conventional specification EP-B- 189 9 45 refers to sizing, and it will be known that the present invention relates to the use of polyurethane to secure paper after sizing natural or synthetic sizing agents on paper K. Further, the coating group of the present invention The necessary characteristic of the finished product is the absence of any pigments • It will not obscure any security features. However, as will be described later • As long as the opacity of the paper does not increase on the UM, various functional additives can exist in the In the application of urethane. The present invention is the result of extensive research and investigation by the inventor, and its purpose is to produce a security document with improved durability and dirt resistance. According to the present invention, security including security features is provided A method of manufacturing paper, which includes forming the paper in a wet state. The paper includes one or more security features, applying a sizing agent on the paper, and then applying undyed polymer on one or both sides of the paper after sizing For the coating of urethane, it can also optionally contain functional additives, as long as the presence of the functional additives does not make the paper less bright «additional U or more · after the box paper • the coating The composition provides a film when poured on the surface of the glass. * It has a Konig hardness from 15 to 13Q and a waterproof test defined by the following steps of K.

Invention description (3) Try: a) The entire formulation for coating was applied to a glass plate to form a film with a dry weight of 80 g / m². b) The film is initially at 2 3t: dry. Once it is no longer sticky, it will be dried for another hour at 80Ό. c) The film is weighed and tested for tensile strength, Young's modulus and visual transparency before wetting. d) The membrane sample is boiled for 30 minutes per liter of water containing 1 g of Na2C03. e) The membrane is then washed in cold water and steps b) to c) are repeated. The membrane was dried and weighed again. If the tested film meets the following requirements, it is classified as waterproof: i) The wet tensile strength of the boiled film and the Young's crossbar should not be less than 90¾ of the initial film's wet tensile strength and Young's weight. ii) The film shows no appreciable decrease in transparency. iii) The weight of the film after drying is not less than 985; Yan Yan showed that the above test can find good polyurethane coating for the purpose of the present invention. The aqueous polyurethane can be in the form of an aqueous suspension. The coating may also be present in the form of an extender such as polyacrylate and thus M-urethane-acrylic blend; this joint must provide a coating with good water and chemical resistance. At the same time • The lower cost of the extender than polyurethane makes the blend much cheaper than polyurethane itself.

Furthermore, the coating can be a second-component component product, which can be cross-bonded with a multi-functional reagent such as melamine / formaldehyde precondensate • polyurethane. Useful cross-linking agents include polyaziridine. The cross-linking agent enhances the water resistance of the undyed polyurethane coating, including cleaning resistance, while providing enhanced security paper and documents manufactured therefrom. The polyurethane composition used in the method of the present invention may still contain components known to those skilled in the art including catalysts, latent solvents and emulsifiers or surfactants. However, it should be noted that because the emulsifier will reduce the effectiveness of the coating under wet conditions. In addition, other known additives may be used including defoamers * flow additives * thickeners or viscosity modifiers. In general, the fewer additives included in the coating composition, the better. * Important properties such as adhesion to the substrate may be adversely affected. The main part of the present invention is to provide an advantageous undyed coating Μ provides the advantages described herein, on the one hand the present invention can use a variety of functional additives to provide documents that can improve the security of the paper prepared from the present invention The specific effect of the preservation of safety • without significantly absorbing the general advantages offered by undyed polyurethane. Those skilled in the art will understand that pigments are added to the coating, especially to provide paper-coated paper or to non-pigment additives that can be used in accordance with the present invention but are sticky additives that meet the following standards: ) —Coated for use with bins • This additive does not increase the opacity of the paper above Π. Anthrax ensures that the additive has no perceptible shadow period for the transparency of the coating.

Description of the invention (5), and therefore retains the general advantages of the undyed coating; b) The additive is in polyurethane The presence of it will not cause failure to pass the test of the present invention for selecting polyurethane *, namely Konig hardness test and waterproof test. The functional additives of the present invention are preferably fluorescent or true pearlescent pigments. The protective functional additives will provide some specific effects to enhance the security or recognizability of documents prepared from the paper of the present invention, and when Additives that are present in the polyurethane coating constitute another additional security feature. Generally speaking, security functional additives are divided into three categories: a) generally identifiable security features such as true pearlescent pigments; b) security features that provide a higher degree of security, which can only be detected by security equipment , Such as fluorescent pigments or magnetic particles; and c) use shielding security features that can be detected by precision detection equipment such as those used in central banks, such as phosphorescent pigments with a certain reduction time. Generally speaking, the coating weight of the polyurethane is between 0.05 and 20 g / m², preferably between 0.5 and 5 g / m². Printed in cooperation with Beigongxiao, Central Bureau of Standards of the Ministry of Economic Affairs (please read the notes on the back before filling in this page). It is better to be after the rubber melts the water roller and before the dryer. When wetting due to glue • Apply polyurethane to the paper. However, polyurethane can also be applied to dry paper after completing the paper making step. It is preferable to apply polyurethane on both sides of the paper. The fibers present in the paper are natural or synthetic male fibers or a mixture of natural and synthetic fibers. This paper is to be used for home use. _ Jia Qi Feng (CNS) Μ specifications (2tOX297 public cleanliness) Printed by the Employees ’Consumer Cooperative of the Central Standards Bureau of the Ministry of Economy ΑΊ _Β7_ V. Description of invention (6) Polyurethane is preferably aliphatic Polyesters are used as a floating liquid. The suspension has a polyurethane concentration of 2% to 70% by weight, and more preferably 5% to 30% by weight of polyurethane. Concentration * Although aliphatic polyether-based polyurethane can also be used in the method of the present invention. At the same time, the polyurethane can also be aliphatic polycarbonate polyurethane. Preferably, the paper used in the method has security properties, which include watermarks or embedded or window lines of visible or hidden security factors. In order to achieve the primary supplement of the present invention, the polyurethane-containing coating must be substantially transparent as illustrated • and preferably has a greater than 4.OniPa 1003; chess though. Advantageously • The polyurethane has an ultimate tensile strength greater than 40 mPa, for example from 40 to 80 mPa, and a Konig hardness greater than 20 seconds, for example from 20 to 40 seconds. In the production of preservative paper, such as paper used for the manufacture of banknotes *, the use of undyed polyurethane coating, as described, is a brand new feature. The method of the present invention provides protective paper with several unexpected and useful properties: a. Polyurethane without fillers is transparent; therefore, it does not interfere with the visible protective properties stored on the paper. b. By reducing the surface porosity and phase roughness, the coating greatly increases the resistance of the paper. This is very important to prolong the circulation life of banknotes. c. Contrary to b), it has been proved by Mae and dry kneading crepe * rubbing and washing tests that coating significantly increases the stickiness of printing and paper surfaces. Xuan is the most surprising.

Description of the invention (7) Ester will cause bad printing sticky effect. d. Unlike dyed m, the polyurethane coating described here does not significantly change the feel and appearance of the paper. This is important because the unusual paper and tactile properties of banknote paper can help the public identify false yarn. e. Going further, coating enhances the clarity and relief of gravure printing. f. Coating also prevents brightener ingestion during cleaning. This is a very important and unexpected property * because the non-fluorescent nature of the banknote paper also assists in the discovery of falsehood. At the same time, it also avoids that the fluorescent light of the brightener confuses any designed fluorescent preservation characteristics stored in the banknotes. g. Coating does not affect the efficiency of the paper manufacturing, conversion or printing process. Especially it will not hinder. The properties resulting from the method of the present invention are the result of the mechanical and chemical resistance and chemical properties of the polyurethane's water resistance test and Konig hardness characteristics as previously defined. Substances that fail these two tests generally fail to meet the specifications required for banknote paper. Another aspect of the present invention provides a method for preparing a security document, wherein the security paper is prepared from the method described hereafter and the resulting security paper is printed to form a security document. The term security documents includes banknotes • Identification documents, driving licenses and passports. The following examples illustrate the invention. In the example, some standard tests that will be described and defined here are referenced.

As shown by the various tests in the first to fifth examples * The paper prepared by the method of the present invention has more enhanced properties than the standard banknote paper. Good printing adhesion is demonstrated by Mae Knead Test, Dry and Soft Tapered Test, Mae Wipe Test and Heavy Cleaning Test. At the same time • The printing resolution of the paper of the present invention is significantly better than that obtained by using Futong's banknote paper. In addition, in particular, the intaglio carving is clearer, and the intaglio relief has also increased. At the same time, the best cultivating resistance means that the coated paper prepared by the method of the present invention absorbs less than two-thirds of the stained substrate compared to the uncoated paper. As shown above, an extender can be added to the coated formulation to reduce costs; it also has advantageous properties such as adhesion to enhance the retention properties of surface application * such as holographic photographs. The extender that can be used in the present invention is generally a water-insoluble adhesive such as styrene / acrylic acid copolymer • acrylated vinyl acetate, vinyl chloride / ethylene copolymer, or vinyl acetate copolymer. They generally fail the waterproof and hardness tests. Alternative extenders are VA / VEOVA copolymers, such as those sold under the trade name Vinamul 6975m. However, as long as the composition containing polyurethane and extender has a specific Konig hardness and passes the water resistance test, and the combination of suitable polyurethane can be satisfactory in terms of the standards set above effect. In the coating formula of the 1QQ part, the extender can be added to 70 *, preferably a concentration of 15 to 50 parts. The strongest and most waterproof extender can be added to this concentration. However, the nature of the box of the coated product is weaker and less resistant to this paper.

Description of the invention (18) The extender of water clearly cannot be added to such a high concentration. A cross-linking agent can be used to increase the waterproofness and hardness of the polyurethane. It can be used to obtain the desired properties of polyurethane which is not suitable. It can also enhance the properties of the polyurethane component * and enable the use of larger amounts of extenders. Suitable cross-linking agents include polyvinyl chloride, carbodiimide, isocyanate and zirconium salts. Other cross-bonding agents such as epoxy resin can also be used, but it is less practical due to its higher heating temperature and longer heating time. In addition, further studies have found that the polyurethane coating of the present invention has additional significant advantages. It has been found that the use of specific polyurethane coatings can improve the durability and visual effects of foils, holograms, and Kinograms. This is because polyurethane significantly reduces the extent to which the cobalt adhesive used to attach holographic photographs is absorbed onto the paper surface. It was found that the adhesive can be used more evenly and result in better adhesion and a more shiny surface. For holographic photographs, the resulting glossier surface is particularly advantageous • because the details of the viewing party in the holographic photographs are significantly clearer. As is well known • Holographic photographs are generally more expensive and when security documents such as banknotes are in circulation, they will undoubtedly have commercial benefits if they can exist for a longer period of time • This is provided by the polyurethane coating of the present invention The result of increased durability.
