More specifically, the present invention relates to a thread having blocking resistance, and a forgery prevention sheet formed by inserting the thread into a predetermined position between paper layers with a paper machine and making the paper.

に、各種の偽造防止対策が施されている。2. Description of the Related Art Recent advances in copy technology have facilitated the forgery of securities and have become a major social problem. Banknotes, gift certificates, checks, stock certificates, passports, identification cards, cards, and the like are illegal. Various counterfeiting prevention measures have been taken to prevent forgery or forgery.

No. 808, JP-B-52-48660, JP-A-51-1
For example, there is a forgery prevention paper referred to as a so-called threaded paper in which a thread (referred to as a thread) is formed between paper layers described in Japanese Patent No. 30308 or the like.

造できず、変造することが困難である。[0004] The form of the thread to be formed between the paper layers is generally about 10 to 100 µm in thickness and 0.2 to 30 mm.
It is in the form of a thread or tape having a width of about one, and a metal-deposited film is generally used. In recent years, holograms, pixelgrams, grating images, etc., which are extremely difficult to duplicate, have been affixed to credit cards, banknotes, etc. to prevent counterfeiting by advanced copier technology. Also used as a thread. The anti-counterfeit paper incorporating these threads cannot be forged in the metallic luster portion of the threads even when copied with a copying machine, and is difficult to falsify.

が偽造、変造の目的に流出される恐れを生じてしまう。However, if the paper layer and the thread are not firmly bonded to each other in the anti-counterfeit paper into which the thread is formed, pulling the thread causes the thread to slip out of the paper layer, thereby impairing the value of the anti-counterfeit paper or falling off. There is a risk that the thread will be leaked for the purpose of forgery or falsification.

備では困難である。As means for solving such a problem, for example, a water-soluble adhesive is used for a size press solution in a paper making process, or a thermoplastic resin is used for a thread as described in JP-A-7-56377. A method of applying a resin or a water-soluble adhesive to improve the adhesive strength to a paper layer, and the like can be given. However, sufficient adhesive strength cannot be obtained with a size press liquid, and it is difficult to apply a thermoplastic resin or a water-soluble adhesive to a thread and to form a paper between paper layers with existing equipment.

点がある。Further, in the method using a thread provided with an adhesive layer in advance, there is a case where threads overlapping inside the take-up block before winding the thread, which hinders the manufacture of anti-counterfeit paper. Because
It was difficult to provide an adhesive layer on both sides of the thread. Further, even if an adhesive having excellent blocking resistance is selected, it is difficult to store the thread winding so as not to hinder use for a long period of time. By the way, if a thread having an adhesive layer provided only on one side is used, there is a disadvantage that the aesthetic appearance as forgery prevention paper is impaired, for example, the paper layer rises from the thread on the side where the adhesive layer is not provided.

るに至った。Means for Solving the Problems The inventors of the present invention have conducted intensive studies on an adhesive applied to a thread used in the manufacture of anti-counterfeit paper, and as a result, without reducing the adhesive strength between the thread and the paper layer. It has been found that thread blocking can be prevented very effectively, and the present invention has been completed.

存される。BEST MODE FOR CARRYING OUT THE INVENTION The thread of the present invention is obtained by applying an adhesive to a wide thread base material, drying it, slitting it into a predetermined width, and winding it on a bobbin. Winding is preferable in terms of production efficiency.
Therefore, the thread of the present invention is usually stored in a wound state for about one week to six months until it is used for papermaking of forgery prevention paper.
【００１３】また、本発明に使用されるスレッドは巻取

接着剤層に潤滑剤を含有させ、接着剤最表面の接着性を

ものである。In order to prevent the thread from blocking even in such a long-term storage, the present invention includes a lubricant in the adhesive layer of the thread, thereby significantly reducing the adhesiveness of the outermost surface of the adhesive. Is to improve.
【００１５】すなわち、スレッドに設ける表裏接着剤層

ことにより、スレッドに接着剤塗工後、該潤滑剤が表面

士のブロッキングを抑制できるものである。That is, a lubricant is previously contained in at least one of the front and back adhesive layers provided on the thread, so that after the adhesive is applied to the thread, the lubricant is unevenly distributed on the surface and the outermost surface is bonded. The blocking of the adhesive layers can be suppressed by reducing the property.

接着強度が低下するため好ましくない。The amount of the lubricant to prevent blocking between the adhesives is 1 to 100 parts by weight of the adhesive.
To 15 parts by weight, preferably 3 to 10 parts by weight. Incidentally, if the amount is less than 1 part by weight, the desired effect of blocking of the present invention cannot be obtained. If the amount exceeds 15 parts by weight, not only is it not economically favorable, but also the adhesive strength with the paper layer decreases. Therefore, it is not preferable.

The mesh was closed by pasting, and a paper layer having a hole of 1 cm × 1 cm was formed every 1 cm as a first paper layer. The second cylinder net cylinder was not worked, and a plain second paper layer was formed.
In addition, the thread unwinding device is installed between the mesh cylinders of the first tank and the second tank, and in a position where the thread overlaps the hole of the first paper layer, the second paper layer and the aluminum deposition surface side are in contact with each other. Made to be inserted. The wet paper (water content: about 50%) produced by this paper machine is dried by 12 cylinder dryers (surface temperature: about 70 to 100 ° C.) and then machine-calendered.
