Description

【0001】
【発明の属する技術分野】
本発明は、用紙表面に薄く水を塗布する等、用紙表面に物質を付与することで用紙表面に模様を浮き出すようにした浮き出し模様を有する用紙に関するものである。
【0002】
【従来の技術】
従来、一般的に用紙においては、ファンシーペーパー用途を除いて、表面にむらや凹凸が存在することは嫌われ、種々の環境条件に晒されても表面が平滑で平坦であることが要請されている。そのため、用紙表面に、水溶性高分子やエマルジョンなどを均一に塗布し、紙面の強度改善やサイズ度の調整などが行われている。
【0003】
また、偽造防止用の用紙においては、透かしを設けたり、特殊な繊維を抄き込んだり、コピー防止用のパターン印刷を行うなどの手段が講じられているが、いずれも自然な風合いの用紙ではない。
【0004】
【発明が解決しようとする課題】
そこで、通常時には平滑で平坦な表面性状で自然な風合いでありながら、随時に用紙表面に適当な物質を付与するなどの簡単な処理を施すことによって特徴的な模様が表示されて、偽造防止用途やファンシーペーパー用途として好適に使用できる用紙が開発されることが望まれる。
【0005】
本発明は、このような課題に鑑み、用紙表面に物質を付与することで用紙表面に模様を浮き出すことができる浮き出し模様を有する用紙を提供することを目的とする。
【0006】
【課題を解決するための手段】
本発明の浮き出し模様を有する用紙は、用紙表面に付与された物質やエネルギーを吸収し若しくは物質と反応して膨張することで用紙表面に模様を浮き出す模様発現部を設けたことを特徴とする。
【0007】
この構成によれば、用紙の表面に薄く水などの液体を塗布したり、特殊なガスを吹き付けたり、光や熱エネルギーを付与する等、随時に物質やエネルギーを付与すると、用紙の模様発現部が物質やエネルギーを吸収して膨潤・膨張したり、物質と反応して膨張することにより模様が浮き出すことになり、必要時に所定の物質やエネルギーを付与することで模様を浮き出させることができる用紙を提供することができ、偽造防止用途やファンシーペーパー用途などに好適に使用することができる。
【0008】
また、用紙に外添するサイズ材の塗布量を模様発現部と他の部分で異ならせると、模様発現部でサイズ度が異なるため、用紙表面に薄く水を塗布すると模様発現部で顕著に水分を吸収し膨潤して模様が浮き出すようにできる。従って、単にサイズ材の塗布量を変えるだけで用紙を製造できるとともに、水を薄く塗布するだけの簡単な処理で模様を発現させることができ、またその後乾燥すると元の状態に復元するため、実用的な用紙で非常に簡単に偽造防止機能を持たせることができる。
【0009】
また、用紙表面に物質透過量を制御するコーティング層を形成するとともに、模様発現部にはコーティング層を形成せず若しくは他の部分とコーティング層の厚さを異ならせると、コーティング層にて用紙内への物質の浸透が制御されることで、主に模様発現部でのみ物質が吸収されて膨潤したり、用紙内に添加された材料と物質が反応して膨張したりして模様が浮き出すようにできる。従って、製品の製造工程の任意の時点でコーティング層を形成することで、任意の箇所に明瞭な模様を浮き出させることができる。
【0010】
また、逆に用紙の模様発現部に、液体を吸収して膨潤したり液体やガスと反応して膨張する物質を塗工又は含浸したり、印刷機を用いて用紙の模様発現部に、液体を吸収して膨潤したり液体やガスと反応して膨張する物質を印刷しても、上記と同様に、模様発現部で物質が膨潤したり、物質が反応して膨張したりして模様が浮き出すようにできる。
【0011】
また、本発明の浮き出し模様を有する用紙の製造方法は、表面に凹凸部分または親水性あるいは疎水性の部分を有するプレスロールを用いて水溶性高分子材料やエマルジョンを用紙に塗布し、液体を吸収して膨潤することで模様を浮き出す模様発現部を形成することを特徴とするものであり、プレスロールの表面に簡単な加工を行うだけで、簡単に上記浮き出し模様を有する用紙を製造することができる。ここで言うプレスロールには、抄紙工程で使用されるプレスロールに限らず、印刷工程で使用される印刷ロール等、表面に凹凸部分または親水性あるいは疎水性の部分を有するロールを好適に使用することができる。
【0012】
【発明の実施の形態】
以下、本発明の浮き出し模様を有する用紙の一実施形態について、図1、図2を参照して説明する。
【0013】
図1において、1は用紙で、通常時は図1(a)に示すように全面が平坦であるが、その表面に薄く水を塗布すると、図1(b)に示すように、模様(図示例ではドーナツ状の模様)2が浮き出して来る。
【0014】
このような用紙1は、抄紙機のサイズプレスロールの表面に比較的深い凹部または凸部を形成してこの凹凸部分で用紙表面にサイズ材が外添されないようにしておき、このようなサイズプレスロールを有する抄紙機を用いて抄紙することで簡単に製造することができる。
【0015】
すなわち、図2(a)に示すように、用紙1の所望箇所にサイズ材3が外添されない部分を形成することで、模様2が発現する模様発現部4を有する用紙1が得られる。その後、この用紙1の表面に、薄く水を塗布すると、サイズ材3の外添されていない模様発現部4において、その水が用紙1の内部に浸透して用紙1を膨潤させるため、図2(b)に示すように、用紙が表面側に突出して模様2が浮き出すことになる。
【0016】
なお、本実施形態では、図2に示すように、用紙1の表面に、模様発現部4を除いて水の透過を抑制するコーティング層5を形成しており、多少多めに水が塗布された場合でも、塗布した水が模様発現部4以外の部分に浸透してその部分が膨潤するのが確実に防止され、模様2をより明瞭に浮きだすことができるとともに、用紙1の模様発現部4以外の部分に悪影響を与えるのを確実に防止することができる。
【0017】
上記実施形態の説明では、サイズ材3の非塗布部とコーティング層5にて模様発現部4を形成した例を示したが、サイズ材3の非塗布部とコーティング層5の何れか一方のみで模様発現部4を形成してもよい。
【0018】
また、上記実施形態では、抄紙機のサイズプレスロールの表面に、凹部又は凸部を設けることでサイズ材3が外添されない模様発現部4を形成する例を示したが、化学的に親水性又は疎水性を有する部分を設けることでサイズ材3が外添されない模様発現部4を形成してもよい。
【0019】
また、抄紙機では、サイズ材3を外添せずに、各種塗布装置や印刷機を用いて非塗布部や塗布量の少ない部分を形成してもよい。
【0020】
また、上記実施形態では、模様2を発現させる際に水を薄く塗布する例を示したが、その他、例えばアルコールやその他の有機媒体などの液体を吸収して膨潤したり、反応して膨張する材料を用紙1に充填しておいて、その液体を塗布することで模様2を浮き出させるようにしても良い。さらに、液体に限らず炭酸ガスや水素ガスやなどのガスと反応して膨張する材料を用紙1に充填しておいて、そのガスを用紙1の表面から吹き付けることで模様2を浮き出させるようにようにしても良い。
【0021】
また、液体やガスなどの物質に限らず、熱や光エネルギーを付与することによって膨張する材料を用紙1に充填しておいて、それらのエネルギーを用紙1の表面に照射することで模様2を浮き出させるようにしても良い。
【0022】
さらに、以上の説明では、用紙1の全体に物質やエネルギーの付与によって膨潤したり、膨張したりする物質が存在し、用紙1の表面を、模様発現部4を除いてサイズ材3やコーティング層5にて覆っているものを示したが、逆に用紙1の表面の内、模様発現部4にのみ液体を吸収して膨潤したり液体やガスと反応して膨張する物質を塗工又は含浸させても良い。
【0023】
【発明の効果】
本発明によれば、用紙の表面に随時に所定の物質やエネルギーを付与すると、用紙の模様発現部が物質を吸収して膨潤したり、物質やエネルギーと反応して膨張することにより模様が浮き出すので、偽造防止用途やファンシーペーパー用途などに使用することで大きな効果を発揮する。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a paper having an embossed pattern in which a pattern is embossed on the paper surface by applying a substance to the paper surface, for example, by applying water thinly on the paper surface.
[0002]
[Prior art]
Conventionally, in general, in paper, except for fancy paper applications, it is disliked that there is unevenness or unevenness on the surface, and it is required that the surface be smooth and flat even when exposed to various environmental conditions. I have. For this reason, a water-soluble polymer, an emulsion, or the like is uniformly applied to the surface of the paper to improve the strength of the paper surface and adjust the sizing degree.
[0003]
In addition, for papers for forgery prevention, measures such as providing a watermark, making special fibers, and performing pattern printing for copy protection have been taken, but in all cases paper with natural texture Absent.
[0004]
[Problems to be solved by the invention]
Therefore, in spite of the fact that the surface has a natural texture with a smooth and flat surface at normal times, a characteristic pattern is displayed by performing a simple process such as applying an appropriate substance to the paper surface as needed, thereby preventing forgery. It is desired to develop a paper that can be suitably used for paper and fancy paper.
[0005]
In view of such problems, an object of the present invention is to provide a paper having an embossed pattern that can emboss a pattern on the paper surface by applying a substance to the paper surface.
[0006]
[Means for Solving the Problems]
The paper having an embossed pattern according to the present invention is characterized in that a pattern expressing portion is provided on the paper surface for absorbing the substance or energy given to the paper surface or expanding by reacting with the substance and expanding. .
[0007]
According to this configuration, when a substance or energy is applied as needed, such as applying a thin liquid such as water to the surface of the paper, spraying a special gas, or applying light or heat energy, the pattern expression portion of the paper is obtained. Swells and expands by absorbing substances and energy, or expands by reacting with substances, so that the pattern emerges, and when necessary, the pattern can be emerged by applying a predetermined substance or energy Paper can be provided, and can be suitably used for forgery prevention use, fancy paper use, and the like.
[0008]
Also, if the application amount of the sizing material to be externally added to the paper is different between the pattern expressing portion and the other portions, the degree of sizing is different in the pattern expressing portion. Can be absorbed and swelled so that the pattern emerges. Therefore, the paper can be manufactured simply by changing the amount of the size material applied, and the pattern can be expressed by a simple process of applying a thin coat of water. It is possible to provide a forgery prevention function very easily with basic paper.
[0009]
In addition to forming a coating layer on the paper surface to control the amount of material permeation and not forming a coating layer on the pattern expressing part or making the thickness of the coating layer different from that of other parts, the coating layer By controlling the permeation of the substance into the paper, the substance is mainly absorbed only in the pattern manifestation part and swells, or the material added to the paper reacts with the substance to expand and the pattern emerges I can do it. Therefore, by forming the coating layer at any point in the manufacturing process of a product, a clear pattern can be raised at any point.
[0010]
Conversely, a material that absorbs a liquid and swells or reacts with a liquid or gas to expand the material is applied or impregnated to the pattern manifestation part of the paper, or the liquid is applied to the pattern manifestation part of the paper using a printing machine. Even if a substance that absorbs and swells and prints a substance that expands by reacting with a liquid or gas is printed, the pattern swells in the pattern expressing portion or the substance reacts and expands in the same manner as described above. You can make it stand out.
[0011]
The method for producing a paper having an embossed pattern according to the present invention comprises applying a water-soluble polymer material or an emulsion to the paper using a press roll having an uneven portion or a hydrophilic or hydrophobic portion on the surface to absorb the liquid. Forming a pattern manifestation portion that emerges a pattern by swelling, and by simply performing a simple processing on the surface of a press roll, easily producing a paper having the above-described embossed pattern. Can be. The press roll referred to here is not limited to the press roll used in the papermaking process, and a roll having an uneven portion or a hydrophilic or hydrophobic portion on the surface, such as a printing roll used in the printing process, is preferably used. be able to.

In FIG. 1, reference numeral 1 denotes a sheet, which is generally flat as shown in FIG. 1 (a), but when a small amount of water is applied to the surface, a pattern (FIG. 1 (b)) is obtained. In the illustrated example, a donut-shaped pattern) 2 emerges.
[0014]
Such a paper 1 has a relatively deep concave or convex portion formed on the surface of the size press roll of the paper machine so that the size material is not externally added to the surface of the paper at the uneven portion. It can be easily manufactured by making a paper using a paper machine having a roll.
[0015]
That is, as shown in FIG. 2A, by forming a portion where the size material 3 is not externally added at a desired portion of the paper 1, the paper 1 having the pattern expressing portion 4 in which the pattern 2 appears can be obtained. Thereafter, when water is thinly applied to the surface of the paper 1, the water permeates into the paper 1 and swells the paper 1 in the pattern expressing portion 4 to which the size material 3 is not externally added. As shown in (b), the paper protrudes to the front side, and the pattern 2 emerges.
[0016]
In the present embodiment, as shown in FIG. 2, a coating layer 5 for suppressing water permeation is formed on the surface of the paper 1 except for the pattern expressing portion 4, and a relatively large amount of water is applied. Even in this case, the applied water is surely prevented from penetrating into a portion other than the pattern expressing portion 4 and swelling, and the pattern 2 can be more clearly raised, and the pattern expressing portion 4 of the paper 1 can be raised. It is possible to reliably prevent adverse effects on other parts.
[0017]
In the description of the above-described embodiment, an example in which the pattern expressing portion 4 is formed by the non-applied portion of the size material 3 and the coating layer 5 is shown, but only one of the non-applied portion of the size material 3 and the coating layer 5 is used. The pattern expressing portion 4 may be formed.
[0018]
Further, in the above embodiment, the example in which the pattern expressing portion 4 to which the size material 3 is not externally added is formed by providing the concave portion or the convex portion on the surface of the size press roll of the paper machine, Alternatively, a pattern expressing portion 4 to which the size material 3 is not externally added may be formed by providing a hydrophobic portion.
[0019]
Further, in the paper machine, the non-applied portion or the portion with a small amount of application may be formed using various coating devices or printing machines without externally adding the size material 3.
[0020]
Further, in the above-described embodiment, an example in which water is applied thinly when the pattern 2 is developed is shown. However, in addition, for example, the liquid 2 such as alcohol or another organic medium absorbs and swells or reacts and expands. The material 2 may be filled in the paper 1 and the pattern 2 may be raised by applying the liquid. Further, a material that expands by reacting with a gas such as carbon dioxide gas or hydrogen gas as well as a liquid is filled in the paper 1, and the gas is sprayed from the surface of the paper 1 so that the pattern 2 emerges. You may do it.
[0021]
The paper 2 is filled with a material that expands by applying heat or light energy, without being limited to substances such as liquids and gases, and the energy is applied to the surface of the paper 1 to form the pattern 2. You may make it stand out.
[0022]
Further, in the above description, there is a substance that swells or expands due to the application of a substance or energy to the entire sheet 1, and the surface of the sheet 1 is removed from the size material 3 or the coating layer except for the pattern expressing portion 4. 5, the surface of the paper 1 is coated or impregnated with a substance that absorbs liquid and swells or reacts with liquid or gas to expand only in the pattern expressing portion 4. You may let it.
[0023]
【The invention's effect】
According to the present invention, when a predetermined substance or energy is applied to the surface of the paper as needed, the pattern expression part of the paper absorbs the substance and swells, or the pattern emerges due to expansion by reacting with the substance or energy. Therefore, it is very effective when used for anti-counterfeiting applications and fancy paper applications.
