Abstract

<P>PROBLEM TO BE SOLVED: To provide inexpensive paper for preventing forgery not requiring a specific facility such as ultraviolet light irradiation equipment in order to discriminate a true paper from a forged paper. <P>SOLUTION: The paper for preventing forgery is obtained by mixing discriminating fine pieces for discriminating the forged paper into second layer pieces of a second layer from surface layer pieces or middle layer pieces of a middle layer in a multilayer paper composed of two or more layers. The discriminating fine pieces for discriminating the forged paper may visually be checked through the surface layer pieces or the discriminating fine pieces for discriminating the forged paper mixed in the second layer pieces or the middle layer pieces may visually be checked by releasing paper pieces of the layer which is upper than the second layer or the middle layer. The paper for preventing forgery can more inexpensively be produced by using a chemical fiber such as rayon, paper pieces or fine pieces of mica, etc., as the discriminating fine pieces for discriminating the forged paper. <P>COPYRIGHT: (C)2004,JPO

Description

【0001】
【発明の属する技術分野】
本願発明は、各種情報が印字・印刷される各種チケットやパッケージ等の偽造防止のために使用される偽造防止用紙に関するものである。
【0002】
【従来の技術及び発明が解決しようとする課題】
従来、偽造防止用紙の一例としては、たとえば、特殊な印字やインク、模様を印刷したり、紙中に蛍光を発する各種蛍光染料を内在させる方法等が知られている(たとえば特開平6−8678号公報)。
【0003】
そして、特殊な印字やインクは専用の印刷機、高価なインクが必要な事から、付加価値の高い用途への利用が図られているが、多量に頒布されるチケットやパッケージのような用途への使用はコスト面で不向きであり、連続番号や別途証紙を貼る等の工夫が必要があった。そのほか、偽造防止用スレッドを混抄した紙なども知られているが、偽造確認のために、ブラックライト等の紫外線照射機器などの設備が必要であるという問題がある。
【0004】
本願発明は、上記従来例のような方法とは異なる、簡便な方法で、正規の用紙と偽造紙を識別できるようにした偽造防止用紙を提供することを目的とするものである。
【0005】
【課題を解決するための手段】
本願発明の偽造防止用紙は、二層以上の層構成を有する多層紙であって、表層片から2層目の第2層片又は該第2層片より中層にある中層片に、偽造紙識別用識別細片を混抄することを基本思想とする。
【0006】
この場合、偽造紙識別用の識別細片が、表層片を通して視認可能とされていてもよく、あるいは、第2層片又は中層片に混抄されている識別細片がそれより上層の紙片を剥離させることにより視認可能となるようにされていてもよい。
【0007】
偽造紙識別用の識別細片としては、レーヨン等の化学繊維や紙片、あるいは雲母等の細片を使用することができる。
【0008】
偽造紙識別用の識別細片を表層片を通して透視できるようにするためには、表層片より2層目の第2層片に識別細片を混抄し、さらに表層の付量を少なく調整するとよい。これに対して、上層紙片を剥離することにより識別細片を視認し得るようにするためには、表層の付量を多く調整する等の方法をとるとよい。
【0009】
【発明の効果】
本願発明の偽造防止用紙によれば、次のような効果がある。
【0010】
▲1▼ 紫外線照射機器などの特別な設備が不要であり、又どこでも偽造紙の識別が可能となる。
【0011】
▲2▼ 表層片以下の第2層片や中層片に偽造紙識別用の識別細片が混抄されているため、印刷による方法では偽造が不可能である。
【0012】
▲3▼ 第2層片又は中層片に混抄される識別細片は、レーヨン等の化学繊維や紙片、あるいは雲母等の安価な材料を使用することができる。
【0013】
【実施例】
以下、本願発明について好適な実施例(識別細片が表層片を通して透視できるもの=第1実施例、剥離することによって識別細片を確認するもの=第2実施例)を説明する。なお、ここでの部は重量基準である。
【0014】
(第1実施例)
5層からなる多層抄き紙の内、表層片は上白古紙30部(絶乾米坪換算、以下同じ)及びコート紙の古紙70部で湿紙を調整した。また、表層片の次層目(以下第2層片と称す)は広葉樹晒クラフトパルプ99部及び着色レーヨン(種類:ブライト短カット品、太さ:11dtex、長さ:10mm、色:グリーン)1部で湿紙を調整した。その他の3層は、段ボール古紙100部で湿紙を調整した。これら湿紙を用い、円網多層抄紙機で抄き合わせ、米坪180g/mの5層からなる多層抄き紙を得た。この時、表層片及び第2層片の付け量を各々34g/m及び35g/mに調整し、識別が表層片を通して透視できる偽造防止用紙が得られた。
【0015】
(第2実施例)
実施例1と同様の手順で5層からなる多層抄き紙を作成した。この時、表層片及び第2層片の付け量を各々45g/mおよび30g/mに調整し、剥離することによって識別を確認する偽造防止用紙が得られた。

TECHNICAL FIELD OF THE INVENTION
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a forgery prevention sheet used for preventing forgery of various tickets and packages on which various information is printed / printed.
[0002]
Problems to be solved by the prior art and the invention
Conventionally, as an example of forgery prevention paper, for example, a method of printing a special print, ink, or pattern, or incorporating various fluorescent dyes that emit fluorescence in the paper is known (for example, JP-A-6-8678). Publication).
[0003]
Special printing and ink require dedicated printing machines and expensive inks, so they are being used for high value-added applications.However, they are used for applications such as tickets and packages distributed in large quantities. However, the use of this is unsuitable in terms of cost, and it was necessary to devise a device such as attaching a serial number or a separate certificate stamp. In addition, a paper mixed with a forgery prevention thread is also known. However, there is a problem that equipment such as an ultraviolet irradiation device such as a black light is required for forgery confirmation.
[0004]
SUMMARY OF THE INVENTION An object of the present invention is to provide a forgery-prevention sheet which is capable of discriminating between a regular sheet and a forged sheet by a simple method different from the method of the conventional example.
[0005]
[Means for Solving the Problems]
The anti-counterfeit paper of the present invention is a multi-layered paper having two or more layers, wherein a counterfeit paper identification is provided on a second layer piece from the surface layer piece to a second layer piece or a middle layer piece from the second layer piece to the middle layer. The basic idea is to mix the identification strips for use.
[0006]
In this case, the identification strip for identifying the counterfeit paper may be visible through the surface layer piece, or the identification strip mixed in the second layer piece or the middle layer piece peels off the upper layer paper piece. By doing so, it may be made visible.
[0007]
As identification strips for identifying forged paper, chemical fibers such as rayon, paper strips, or strips such as mica can be used.
[0008]
In order to allow the identification strip for identification of forged paper to be seen through the surface layer piece, the identification strip is mixed with the second layer piece of the second layer from the surface layer piece, and the amount of the surface layer may be further reduced. . On the other hand, in order to make the identification strip visible by peeling off the upper layer paper piece, a method of adjusting the amount of the surface layer to be large may be adopted.
[0009]
【The invention's effect】
The anti-counterfeit paper of the present invention has the following effects.
[0010]
{Circle around (1)} Special equipment such as an ultraviolet irradiation device is not required, and it is possible to identify fake paper anywhere.
[0011]
{Circle around (2)} Since identification strips for identifying forged paper are mixed in the second layer piece and the middle layer piece below the surface layer piece, forgery is impossible by a printing method.
[0012]
{Circle around (3)} As the identification strip mixed in the second layer piece or the middle layer piece, an inexpensive material such as rayon or other synthetic fiber, paper piece, or mica can be used.
[0013]
【Example】
Hereinafter, a preferred embodiment of the present invention (one in which the identification strip can be seen through the surface layer piece = first embodiment, and one in which the identification strip is confirmed by peeling = second embodiment) will be described. The parts here are on a weight basis.
[0014]
(First embodiment)
Among the multilayer paper made of five layers, the surface layer pieces were prepared by using 30 parts of used white paper (in terms of absolute dry rice basis, the same applies hereinafter) and 70 parts of coated paper. The next layer of the surface layer piece (hereinafter referred to as a second layer piece) is 99 parts of hardwood bleached kraft pulp and colored rayon (type: bright short cut product, thickness: 11 dtex, length: 10 mm, color: green) 1 The wet paper was adjusted in the section. For the other three layers, wet paper was prepared using 100 parts of corrugated cardboard waste paper. Using these wet papers, they were laminated with a circular-mesh multilayer paper machine to obtain a multilayer paper made of five layers of 180 g / m 2 in rice tsubo. At this time, each of the attached amount of the surface layer piece and the second layer piece was adjusted to 34g / m 2 and 35 g / m 2, identification was obtained anti-falsification paper that can be transparent through the surface layer pieces.
[0015]
(Second embodiment)
In the same procedure as in Example 1, a multilayer paper made of five layers was prepared. At this time, by adjusting the assigned weight of the surface layer piece and the second layer piece each 45 g / m 2 and 30 g / m 2, falsification paper was obtained to confirm the identification by peeling.
