More specifically, the present invention relates to an anti-counterfeit paper in which only a copy or a copy having a color tone completely different from that of the original (genuine) can be obtained even if an attempt is made to copy by a color copying machine or copy by an image processing system.

Description of the Related Art Recently, the accuracy of copying machines has been remarkably improved, and in particular, the spread of electrophotographic color copying machines has facilitated the forgery of various securities and has become a social problem. To prevent this, various anti-counterfeiting measures have been considered. One of them is that the present copying machines cannot reproduce a glittering material such as metallic color or interference color. There is something.

もある。For example, as proposed in Japanese Utility Model Laid-Open No. 58-168754, a copy is prepared by providing a bright plate such as aluminum foil having a remarkable metal color tone on the upper surface of a base paper and providing a letter pattern on the surface of the bright plate. There is a proposal for non-copyable paper by machine.
When this is copied, the character pattern applied to the paper surface becomes unreadable because the foil surface is blackened when the light is emitted from the copying machine. This paper has the advantage that copying itself is impossible (the copy cannot be read), but the disadvantage is that the metallic color is overemphasized because of the large area occupied by the bright printing paper, which is uncomfortable. Further, there are other problems such that the manufacturing process of the paper becomes complicated, the cost is inevitably increased, and it is difficult to collect the papermaking fibers from the waste paper.

て、カラー複写機で複写しても元の原稿と異なった色相
に複写されるか、あるいは全く複写されなければ本物か
否かの判定が出来ることに着目した。The present inventors have conducted investigations with the objective of solving these problems. The inventors of the present invention have changed their minds and noticed that even if a color copying machine is used for copying, it is possible to judge whether the original is copied in a hue different from that of the original, or if it is not copied at all, it is genuine. .

た。The inventors of the present invention first divided a silver-colored aluminum vapor-deposited polyester film having excellent glitter into pieces,
We considered making it into paper. Since the metallic luster cannot be reproduced by the color copying machine in the paper manufactured in this way, the area where the strips are mixed is simply copied in black, which proves that the paper has anti-counterfeiting ability. However, it has been found that in the paper manufactured in this manner, the strip does not firmly adhere to the paper, and the strip comes off during printing, which causes a serious problem.

The gist of the present invention is to provide an anti-counterfeit paper in which glittering strips are unevenly distributed in the flow direction of the base paper on the surface of the base paper, and the strips can be adhered to the base paper in the papermaking process. It is an anti-counterfeit paper which has various performances.

By doing so, the strips are unevenly distributed near the surface of the base paper. That is, the strips are exposed on the surface of the base paper, and the other part is sunk into the vicinity of the surface and becomes unevenly distributed near the surface.

の欠点を解決し他の手段で同様な効果のある偽造防止用
紙を開発することを課題とする。As a result of further study by the present inventors, the use of the strip having pearl luster causes the metal-specific glare when unevenly distributed on the surface of the paper, as compared with the case where the strip having the metallic luster is used. It was found that they have no discomfort and have a gentle pearly luster, and also have excellent anti-counterfeiting ability. It is inevitable that the strips are distributed with a certain width on the paper by the method of sprinkling the strips in a streak pattern. For example, 10
It is very difficult to manufacture such that it is distributed below the width of mm. This imposes restrictions on the design when a predetermined item is printed on the surface of the paper later. It is an object of the present invention to solve this drawback and develop anti-counterfeit paper having the same effect by other means.

い。In the present invention, it is preferable to use a binder that is insoluble in cold water but soluble in hot water as the binder. A preferred example of the binder having such properties is polyvinyl alcohol. Polyvinyl alcohol can be synthesized by changing the degree of polymerization and the degree of saponification, and the melting temperature in water can be changed. As will be described in detail later, the band-shaped material produced by using such a binder does not elute the binder from the band-shaped material in the wet part of the papermaking process, and the swelling or a part thereof is eluted by the heat of the dry part, and then the When dried, it has a property of firmly adhering to the paper layer. This is a preferable property when it is used for offset printing. That is, strips and paper layers are not peeled off from the blanket during offset printing. In the present invention, it is particularly preferable to use a binder that is soluble in hot water at 60 to 80 ° C., since it has high water resistance to cold water (is difficult to elute in water) and high adhesiveness to a paper layer.

80 to 300 parts by weight of the binder is mixed with the parts by weight. At this time, auxiliary materials such as an antifoaming agent, an antiseptic agent, an antifungal agent, and a viscosity adjusting agent can be appropriately mixed so long as they do not hinder the present invention. The coating liquid prepared in this manner usually has a basis weight of 10 to 10.
Coating amount of 2 on 60g / m2 (absolute dry basis, same below) base paper
It is applied at 10 to 10 g / m2, preferably 3 to 5 g / m2.
It is preferable that the base paper is as excellent in surface smoothness as possible in order to give the pearlescent pigment a bright feeling. One example is a white pigment-coated paper excellent in water resistance, but the results of studies by the present inventors show that the paper of the present invention is not provided with a pigment coating layer, for example, fine paper can sufficiently achieve the object of the present invention. confirmed. The base paper is preferably sized so as to prevent penetration of the coating liquid, and also preferably has wet water resistance.

The coating is applied to one side or both sides. At this time, coating liquids that emit different iris colors were prepared, and coating was performed using a printing machine so that the hues would change one after another in a striped pattern. It begins to emit an iris color. The anti-counterfeit paper manufactured by using this can further enhance the anti-counterfeit ability. Further, the anti-counterfeiting ability is further improved by applying a dot coating layer of various shapes by a printing means instead of the stripe shape.

ールがその好適な例である。There is an inverse correlation between the strength of pearl luster and the adhesive strength with the paper layer. The pearl luster can be increased by increasing the ratio of the pearl pigment, but then the ratio of the binder is inevitably decreased and the adhesive strength to the paper layer is weakened. The present inventors have made the following conclusions as a result of investigating a method for simultaneously enhancing the conflicting performances. That is, in order to further improve the pearl luster and the adhesiveness to the paper layer, 85 to 50 parts by weight of a pearl pigment and 15 to 50 parts by weight of a binder insoluble in cold water and soluble in hot water are mainly used. A pearl pigment coating layer is provided, and a surface coating layer made of a binder which is insoluble in cold water but soluble in hot water is further provided thereon. As this binder, it is particularly preferable to use a binder that is soluble in hot water at 60 to 80 ° C., since polyvinyl alcohol has high water resistance to cold water and high adhesiveness to the paper layer, and polyvinyl alcohol is a suitable example thereof.

物は蛍光色を発し真贋を容易に判定できる。In the present invention, the base paper coated with the pearl pigment may be used in combination with a fluorescent coloring agent which emits a fluorescent color by ultraviolet rays. It is also possible to use a fluorescent coloring agent that emits a fluorescent color with ultraviolet rays together with the pearl pigment coating liquid. In these cases, it is preferable that the base paper is not used together with a fluorescent coloring agent that emits a fluorescent color. By doing so, the band-shaped material emits a fluorescent color when it is irradiated with ultraviolet rays, but when viewed under an ordinary light source, the appearance is almost the same as when the fluorescent coloring agent is not used together. By doing so, the anti-counterfeit performance of the paper can be further enhanced. By irradiating the paper with ultraviolet rays, the band-shaped material emits a fluorescent color, and the authenticity can be easily determined.

This work is performed, for example, by partially coating a resin on the upper net, laminating a resin plate having a predetermined shape, laminating a metal plate, or the like. For the second tank, use a net on a cylinder cylinder without any work. The paper layer (wet paper) formed in the first tank is transferred to a blanket, and the paper layer formed in the second tank is overlaid and kneaded. At this time, the strip-shaped material is drawn out and inserted between the paper layer formed in the first tank and the paper layer formed in the second tank. At this time, it is necessary that the strip-shaped material is drawn out to the window opening portion. . In the present invention, a combination of a cylinder paper machine and a Fourdrinier paper machine or a Fourdrinier paper machine can be adopted for paper production. In the present invention, it is also possible to apply starch, polyvinyl alcohol, various surface sizes, and the like on the paper surface during the papermaking process with a size press device or the like.

される。The paper web thus formed is dried by being heated in a drying zone of a paper machine such as a cylinder dryer or a Yankee dryer. In the early stage of drying, the web contains a large amount of water.Therefore, when a binder that is soluble in hot water is used in the coating layer of the strip, the binder swells or a small part of it dissolves and is dried in the drying zone. By doing so, it firmly adheres to the paper layer. Subsequently, in order to impart surface smoothness to the paper, a machine calendering treatment or a super calendering treatment is appropriately performed to manufacture the anti-counterfeit paper of the present invention.

様の効果が得られる。In the present invention, the portion corresponding to the window opening has a small amount of papermaking fibers. Therefore, when the window opening has a width wider than that of the belt-like material, that portion is not visible when the paper is seen through. It looks bright compared to the surroundings. This effect is similar to the so-called "white watermark" effect, and the present invention can positively utilize this to further enhance the forgery prevention effect. This is an example in which the strip 4 is inserted into the window opening 2 (in this example, the lion pattern in this example) formed in a pattern as shown in FIG. 3 by the printing means. Similar effects can be obtained by forming characters instead of patterns.

It is preferable to employ a design in which printing is not performed on the strip-shaped portion having pearly luster, but pearlescence is recognized even when the ink is applied to the strip-shaped portion. It is more difficult to confirm the existence of the band-shaped material as compared with the case where the ink is not applied. Even if an attempt is made to counterfeit the securities produced in this way using a color copier, the pearl luster of the strip is not reproduced, and the copy shows a strip that appears darker than the surroundings when seen through the light beam. Since it doesn't exist, you can immediately check whether it is genuine or not.

できる。As described above, the anti-counterfeit paper of the present invention is manufactured and has the following remarkable advantages. 1) The band-shaped material has excellent luster and has a gentle pearly luster so that it does not give a feeling of strangeness to the paper, and is excellent in design. 2) Even if an attempt was made to make a copy using a color copier or an image processing was used to make a copy using a color printer, the glitter of the band could not be reproduced, and the copy or copy was seen through the light beam. In that case, since there is no band-like object that appears darker than the surroundings, it is possible to immediately confirm whether it is genuine or not. 3) When a belt-shaped material produced by coating a base paper with a coating liquid prepared by mixing a pearl pigment with a binder soluble in hot water is used, the belt-shaped material firmly adheres to the paper layer in the papermaking process. Stripping of strips and paper layers on the blanket is eliminated. 4) A coating layer having a two-layer structure, that is, a structure having a pearl pigment coating layer and a binder layer can simultaneously improve the contradictory performances of glitter and adhesiveness. 5) By using a synthetic polyolefin-based pulp in combination with the base paper for producing the strip, the strip with improved durability of the slitter blade can be produced. 6) When a belt-like material using a base paper mainly composed of papermaking fibers is used, the papermaking fibers can be easily recovered from damaged paper or waste paper. 7) Taking advantage of such characteristics, the anti-counterfeit paper of the present invention can be used for checks, stock certificates, bonds, banknotes, gift certificates, passports,
It can be suitably used for various counterfeit prevention applications such as tickets and boarding tickets, as well as applications requiring design of posters, pamphlets, greeting cards, envelopes, labels and the like.
