とが困難となる大きな問題点を有している。[Problems to be Solved by the Invention] However, these conventional methods are not elegant because there is no difference between the unevenness of the pattern portion and the non-pattern portion, or the difference is small, and the method of Japanese Examined Patent Publication No. 250-25048. Has a problem in that a uniform transparency cannot be obtained in the non-patterned portion, and the resin adheres to and accumulates on the hot roll during manufacturing, which makes continuous operation difficult. Further, the method of Japanese Examined Patent Publication No. 50-3802 has a big problem that it becomes difficult to make transparent when the base paper becomes thick.
本発明はこれら従来の方法の問題点を解決したもので
ある。The present invention solves the problems of these conventional methods.

レスで処理して製造している。Composition of the Invention Designed papers in which the amount of fibers in the thickness direction of the paper is almost uniform and the pattern portion is a convex portion are known, and generally, the embossing treatment is performed on the paper, or the wet paper on the paper machine is embossed. It is processed by a felt press and manufactured.

とが判った。It is easily predictable that a transparent convex design paper can be obtained by using this design paper as a base paper and impregnating it with a clarifying agent. In addition, since the non-patterned portion of this base paper has a higher density than the convex portion, the transparentizing agent is more impregnated in the low-density convex portion. However, even when actually manufactured by such a method, as will be described later, there is no large difference in transparency between the convex pattern portion and the non-pattern portion, and an excessive amount of the clarifying agent stays on the surface of the non-pattern portion. As it is dried, it causes a defect called "shining", in which the glossiness of that part is large,
It turns out that only design paper with low commercial value and poor taste can be obtained.

本発明を完成したものである。As a result of diligent studies, the inventors of the present invention have processed the pattern under a certain specific condition so that the convex pattern portion is much more opaque than the non-pattern portion, and the contrast between the convex pattern portion and the non-pattern portion is large. For the first time, we found that there is no "shining", and therefore a design paper with great practical value can be manufactured.
The present invention has been completed.

に関する。That is, the present invention imparts a convex pattern and a non-patterned portion to a base paper having a substantially uniform fiber amount in the thickness direction, and makes the clarifying agent dissolved in the container solvent to be less than or equal to the void volume occupied by the non-patterned portion. After the coating, it is dried to obtain a design paper in which the transparency of the difference between the convex pattern and the non-patterned part is increased, and further, the convex pattern is provided only on one side of the base paper, and the opposite side of the convex surface ( It relates to obtaining a design paper coated with a clarifying agent from a smooth surface).

紙は本発明には適さない。[Means for Solving the Problem] The base paper used in the present invention needs to have a substantially uniform fiber amount in the thickness direction, and to have convex and non-patterned portions on its surface. . Therefore, a base paper having a non-uniform fiber amount in the thickness direction, for example, Japanese Patent Publication No.
50-32564, Japanese Patent Publication No. 51-44206, and other stencil papers that intentionally break the texture or stencil papers are not suitable for the present invention.

ルト等で押圧賦型処理する方法等で製造する。The base paper used in the present invention is a paper machine, or a method of pressing a wet paper having a water content of about 15% hydrated into a papermaking paper with an embossing roll such as rubber, metal, or synthetic resin, and water on the paper machine. A wet paper with a rate of about 50% is manufactured by a method such as press-molding with felt having a knitting pattern.

併用することも可能である。The material used for the base paper may be wood pulp, non-wood plant pulp, synthetic pulp such as polyolefin, or synthetic fiber such as rayon, vinylon, nylon, polyester, or a mixture thereof. Further, if necessary, various fillers, colorants, sizing agents, paper-strengthening agents and the like can be appropriately used in combination.

ただし、意匠によってはこれにとらわれるものではな
い。The area of the convex pattern is generally 70% of the total area of the base paper.
% Or less is preferable. When the area of the convex pattern part exceeds 70% when the base paper is made transparent, the area of the non-pattern part, that is, the part with large transparency decreases, and the contrast with the convex pattern part with small transparency (large opacity) This is because it is often difficult to recognize and the design effect is reduced.
However, it is not limited to this depending on the design.

になり、また樹脂付着量も少ないので透明化効果も低い
からである。In the present invention, the base paper produced in this manner is coated with a clarifying agent dissolved in an organic solvent to make the non-patterned portion transparent.
A water-based clearing agent, that is, a liquid in which a water-soluble resin is dissolved in water,
Alternatively, if an aqueous synthetic rubber latex or a synthetic resin emulsion is used, the intended effect cannot be obtained. Water-soluble polymers such as polyvinyl alcohol, starch, casein, carboxymethylcellulose, polyvinylpyrrolidone, polyacrylamide, polyethylene oxide are 10
It has a high viscosity even at about 10% concentration, so even if it is coated, it does not easily penetrate into the base paper, tends to stay on the surface, causing "shining", and the resin adhesion amount is small, so the transparency effect is also low. is there.

塗工はゴムまたは樹脂が微細な粒子を形成しているので

ることができない。In addition, when coating synthetic rubber latex or synthetic resin emulsion, the rubber or resin forms fine particles, so the filter action works on the base paper, especially in the non-patterned areas where the density is high, and it penetrates into the base paper. Can not achieve the purpose.
これに対し、合成樹脂等を有機溶剤に溶解した透明化
剤は高濃度で低粘度の溶解液を容易に得ることができ、

で、本発明に好適に使用できる。On the other hand, a clarifying agent obtained by dissolving a synthetic resin or the like in an organic solvent can easily obtain a high-concentration, low-viscosity solution,
It can be suitably used in the present invention because it has a high permeability to the base paper and a large resin adhesion amount.

点がある。The present invention dissolves these clarifying agents in organic solvents,
Examples of solvents that can be used are benzene, toluene,
Aromatic hydrocarbon solvent such as xylene, petroleum solvent such as gasoline and petroleum ether, ester solvent such as ethyl acetate and butyl acetate, ketone solvent such as acetone, methyl ethyl ketone, methyl isobutyl ketone and cyclohexanone, methylene chloride , Chlorinated hydrocarbon solvents such as trichlorethylene, alcohol solvents such as methyl alcohol, ethyl alcohol, propyl alcohol, butyl alcohol and methyl cellosolve, and these solvents may be used alone or as a mixed solvent. The concentration of the clarifying agent dissolved in the organic solvent is 15% or more, and its viscosity is 80 cp.
s (using a centipoise, B-type viscometer, measured with a # 1 rotor at 60 rpm, the same applies hereinafter) and below are preferable. 15%
In terms of the following concentrations, the resin adhesion amount required for transparency cannot be obtained, and if it is 80 cps or more, penetration into the base paper is insufficient, the transparency effect is also insufficient, and the surface "shine" becomes large. There is.
また本発明では透明化剤の他に硬化剤、任意の着色
剤、界面活性剤、可塑剤等を適宜混合して使用できる。Further, in the present invention, a curing agent, an optional colorant, a surfactant, a plasticizer and the like can be appropriately mixed and used in addition to the clarifying agent.

を充填できる量以下にすることが必要である。In the present invention, the clarifying agent-containing liquid thus prepared is applied to the base paper, but the object of the present invention can be achieved only by the coating method. That is, the difference in transparency between the convex pattern portion and the non-pattern portion is larger in the coating method than in the impregnation method, and this is the greatest feature of the present invention. Further, the coating amount needs to be equal to or less than the amount capable of filling the non-patterned portion.
その理由を図面に基づき説明する。図１、及び図２は

面を示す模式図である。The reason will be described based on the drawings. 1 and 2 are schematic views showing enlarged cross sections of a part of the base papers P and P'used in the present invention.

賦型処理する方法等で製造したものである。The base paper of FIG. 1 is, for example, a method of press-molding wet paper having a moisture content of about 50% on a paper machine with felt having a knitting pattern, or press-molding with two embossing rolls engraved with the pattern. It is manufactured by a treatment method or the like.

押圧処理する方法等で製造したものである。In addition, the base paper of FIG. 2 is a method in which a wet paper with a water content of about 15% that is hydrated on a paper machine or formed paper is pressed through an embossing roll and a counter roll with a flat surface by forming an uneven pattern. Etc. are manufactured.

いるものとする。また、V2は体積F2の繊維と空隙A2より
形成され、V2′は体積F2′の繊維と空隙A2′より形成さ
れているものとする。The volumes of the convex pattern portions 1 and 1 ′ are V 1 and V 1 ′, the volume of the non-pattern portion 2 and 2 ′ of the same area as V 2 and V 2 ′, and V 1 is a fiber of volume F 1 . Void (equivalent to air) A 1
Therefore, it is assumed that V 1 ′ is formed by fibers of volume F 1 ′ and void A 1 ′. Further, it is assumed that V 2 is formed by fibers of volume F 2 and voids A 2, and V 2 ′ is formed by fibers of volume F 2 ′ and voids A 2 ′.
本発明では、紙の厚み方向の繊維量はほぼ均一である
ので、F1≒F2であり、またF1′≒F2′である。また、V1
＞V2、V1′＞V2′である。In the present invention, the amount of fibers in the thickness direction of the paper is substantially uniform, so that F 1 ≈F 2 and F 1 ′ ≈F 2 ′. Also, V 1
> V 2 , V 1 ′> V 2 ′.

A1′＞A2′であるので、凸模様部の透明化剤の付着量
は、非模様部より多くなる。A clarifier with a concentration of 30% (specific gravity 1) is added to this base paper.
In the convex portions 1 and 1 ', the clarifying agent fills the void volumes A 1 and A 1 '. Therefore, the adhering amounts of the clarifying agent after drying are 0.3A 1 and 0.3A 1 ', and similarly, the non-patterned portions 2 and 2'are 0.3A 2 and 0.3A 2 '. A 1 ＞ A 2 and
Since A 1 ′> A 2 ′, the amount of the transparentizing agent deposited on the convex pattern portion is larger than that on the non-pattern portion.
これに対し、透明化剤を塗工する方法では、乾燥後に
0.3A2および0.3A2′の付着量になるような量を塗工する
と、凸模様部も非模様部も同一の付着量（0.3A2および
0.3A2′）となる。On the other hand, in the method of applying the clarifying agent, after drying,
When the amount of coating is 0.3A 2 and 0.3A 2 ′, the same amount (0.3A 2 and 0.3A 2
0.3A 2 ′).

よびA2′を満たす量以下にすることが好ましい。That is, according to the coating method, the resin adhesion amount of the convex pattern portion can be reduced by the impregnation method, and the contrast of transparency of the convex pattern portion and the non-pattern portion can be further emphasized. Therefore, in the present invention, the coating amount of the coating agent is preferably not more than the amount satisfying the void volumes A 2 and A 2 ′ of the non-patterned portion.

る「照り」と称する欠点を生ずるようになる。これに対
し、塗工法では予め必要な透明化剤の量を自由に制御で
きるので、この欠点を少なくすることができる。Actually, in the case of the impregnation method, since the base paper passes through the impregnating liquid in the impregnation tank, the clarifying agent is excessively supplied and tends to stay in the non-patterned portion. When it is dried, it becomes as if a resin film had been formed on the surface of the non-patterned portion, which causes a defect called "shining" in which a large amount of light is reflected at that portion. On the other hand, in the coating method, the necessary amount of the clarifying agent can be freely controlled in advance, so that this drawback can be reduced.
特に、片面のみに凸模様がある原紙（図２に模式的に
示した）を使用し、凸模様のある面と反対面（平滑な
面）から塗工すれば透明化剤の滞留がないので「照り」
の皆無な意匠紙を製造できる。In particular, if a base paper with a convex pattern on only one side (schematically shown in FIG. 2) is used and coating is applied from the surface opposite to the convex surface (smooth surface), there will be no retention of the clarifying agent. "Shiritsu"
It is possible to manufacture design paper that has no
また、含浸法では乾燥ゾーンのガイドロール等に透明
化剤が徐々に堆積し乾燥するので、その対策を施す必要
があるのに比べ、本発明の塗工法ではこの問題は殆ど起
らないと言う大きな利点もある。Further, in the impregnation method, the clarifying agent gradually accumulates on the guide rolls in the drying zone and dries, so that it is necessary to take measures against it, but in the coating method of the present invention, this problem hardly occurs. There are also great advantages.
また、模様部と非模様部の透明度を塗工量を変化する
ことで自在にコントロールできる利点もある。Further, there is also an advantage that the transparency of the pattern portion and the non-pattern portion can be freely controlled by changing the coating amount.
