るからである。DETAILED DESCRIPTION OF THE INVENTION Water-soluble thickeners such as starch, gum arabic, and water-soluble cellulose derivatives have been known and put into practical use as paper adhesives. It takes time for these adhesives to reach a bonding strength equal to or higher than that of paper, and when bonding warped paper or continuous bonding, the adhesive surface must be pressurized for a while. It was necessary. This is because water-soluble thickeners such as starch, gum arabic, and cellulose derivatives are dissolved or swollen in the medium, so it takes time for the medium to evaporate and increase the viscosity.

徴とする。The present inventors previously disclosed in Japanese Patent Application Laid-Open No. 62-283177,
We have proposed an instant adhesive for paper that can obtain an initial adhesive strength equal to or higher than the strength of paper almost instantaneously, that is, in about 5 to 15 seconds, by applying it to paper and then bonding it together. This instant adhesive for paper is made by dispersing a water-insoluble adhesive resin in an aqueous medium, and when it is applied to paper and bonded together, the aqueous medium is selectively absorbed into the paper, and the initial state is initialized within 15 seconds. It is characterized by having a viscosity and solid content concentration such that a sticky resin layer having an adhesive force of 0.1 kg/ca1 or more is formed.
この紙用接着剤は紙へ塗布するまでは低粘度で流動性の
液体であるが、紙へ塗布し貼り合わせた時は、その水性
媒体が紙の内部へ選択的に吸収され、紙と紙の間で十分
に高い初期接着強度を持った粘着性樹脂の層を極めて短
時間で形成する。This paper adhesive is a low-viscosity, fluid liquid until it is applied to paper, but when it is applied to paper and bonded together, the aqueous medium is selectively absorbed into the paper, causing the paper to bond with the paper. A layer of adhesive resin with sufficiently high initial adhesive strength is formed between the two in an extremely short time.
そのためキャップつきの先端に海綿状のペン先を備えた
フェルトペン式塗布器具を用いて紙面に塗布することが
できる。また、非吸水性の紙面以外の表面例えば机の表
面に接着剤が付着しても、水を含んだ布等で拭き取るこ
とができ、またフェルトペン式であるため紙面の隅へ正
確に塗布することができるので通常下紙を用いる必要が
ない。Therefore, it can be applied to the paper surface using a felt-tip applicator with a capped tip and a spongy tip. In addition, even if adhesive adheres to surfaces other than non-absorbent paper, such as the surface of a desk, it can be wiped off with a damp cloth, and since it is a felt-tip pen type, it can be applied precisely to the corners of the paper. Therefore, there is no need to use a base paper.
しかしながらこの接着剤液は合成樹脂エマルジョンであ
るため塗布直後白色であり、そのため塗布面の境界線が
明瞭でなく、折角フェルトペン式の塗布器具を採用して
も塗布面の制御が困難であった。However, since this adhesive liquid is a synthetic resin emulsion, it is white immediately after application, so the boundaries of the applied surface are not clear, and it is difficult to control the applied surface even if a felt-tip pen-type applicator is used. .
そこで本発明は、特開昭６２−２８３１７７号の紙用瞬
間接着剤へ顔料を添加し、塗布面の確認を容易としたも
のである。Therefore, in the present invention, a pigment is added to the instant adhesive for paper disclosed in JP-A No. 62-283177, thereby making it easier to check the coated surface.
本発明の接着剤に使用し得る水不溶性の粘着性樹脂とし
ては、ポリ酢酸ビニル樹脂、アクリル樹脂、およびそれ
らの混合物などが挙げられる。これらの樹脂は元来紙の
強度以上の接着強度を有することが必要である。Water-insoluble adhesive resins that can be used in the adhesive of the present invention include polyvinyl acetate resins, acrylic resins, and mixtures thereof. These resins are originally required to have adhesive strength greater than the strength of paper.
水に不溶性の粘着性樹脂は、モノマーの状態で界面活性
剤を用いて水中に分散して重合される。A water-insoluble adhesive resin is dispersed in water using a surfactant in a monomer state and then polymerized.
分散した粒子の粒径は一般に０．００５〜５ミクロンで
あれば紙へ塗布した時表面へ粒子同士が凝集して樹脂層
を形成する。If the particle size of the dispersed particles is generally 0.005 to 5 microns, when applied to paper, the particles will aggregate to the surface to form a resin layer.
本発明の接着剤は、キャップつきの先端に海綿状のペン
先を備えたフェルトペン状の容器に収容し、使用時ペン
先を押して弁を開き、ペン先を濡らし、紙へ塗布するこ
とによって使用する。The adhesive of the present invention is stored in a felt-tip pen-like container with a capped tip and a spongy tip, and when used, the pen tip is pressed to open the valve, the pen tip is wetted, and applied to paper. do.
このようなフェルトペン式の弁に作られた５龍以下の隙
間からの自然流出が求められる塗布器具の使用を可能と
するためは、接着剤の粘度は６００ ｃｐｓ以下（Ｂ型
粘度肝ローター２号使用、６ｒｐｍ。In order to enable the use of an applicator that requires natural outflow from a gap of 5 or less made in such a felt-tip valve, the viscosity of the adhesive must be 600 cps or less (type B viscosity liver rotor 2). No. used, 6 rpm.
２０℃）でなければならないことが判明した。20°C).
従来の技術によって塗布作業の改善および５凋１以下の
弁の隙間からペン先に自然流出させるために粘度を下げ
れば可能になることは容易に推測できる。しかしながら
貼り合わせて１５秒以内に０゜１０／ｃｍ２以上の初期
接着力を達成しようとするときは溶媒の揮発を早くし、
溶液粘度をできる限り高くして達成しようとするであろ
う。しかし本発明はこれら従来の技術で考えられる方法
とは逆にペン先に流出した接着剤がペン先で固化するこ
とを防ぐために溶媒の揮発を遅くし溶媒が紙に吸収し易
くするためにできるだけ粘度を低くすることが要求され
る。It can be easily surmised that it would be possible to improve the coating operation using conventional techniques and reduce the viscosity to allow the paint to flow naturally into the pen tip through the gap in the valve of less than 5 mm. However, when trying to achieve an initial adhesive strength of 0°10/cm2 or more within 15 seconds of bonding, the solvent must be evaporated quickly.
One would try to achieve as high a solution viscosity as possible. However, contrary to the methods considered in the prior art, the present invention is designed to slow down the volatilization of the solvent and make it as easy as possible to absorb the solvent into the paper in order to prevent the adhesive spilled to the pen tip from solidifying at the pen tip. Low viscosity is required.
水に不溶性の粘着性樹脂を水性媒体中に分散してなる接
着剤溶液の粘度が６００ｃｐｓ以下である時流動性が著
しく改善されるため、貼り合わせた時薄く均一に展げら
れ水が急速に低側へ吸収され、粘着性樹脂の粒子が連り
合って強大化し紙の表面に残る。When the viscosity of the adhesive solution, which is made by dispersing a water-insoluble adhesive resin in an aqueous medium, is 600 cps or less, the fluidity is significantly improved, so that when laminated together, it can be spread thinly and uniformly, and water can rapidly drain away. It is absorbed to the lower side, and the sticky resin particles join together to become stronger and remain on the surface of the paper.

水性媒体中に分散してなる接着剤溶液組成であっても１
２００ｃｐｓを越えるものは紙と接触したとき、接着剤
溶液と紙の間に水に不溶で水の気化、浸透を妨げる樹脂
層が形成され１５秒以内に０．１０ ｋｇ／ｃｎ！の初
期接着力を達成することができない。Even if the adhesive solution composition used in the present invention is made by dispersing a water-insoluble adhesive resin in an aqueous medium,
If the adhesive exceeds 200 cps, when it comes into contact with paper, a resin layer is formed between the adhesive solution and the paper that is insoluble in water and prevents water from vaporizing and permeating, resulting in a drop of 0.10 kg/cn within 15 seconds! initial adhesion force cannot be achieved.
他方、接着剤中の粘着性の濃度があまり低いと、紙の表
面に付着する樹脂の量が少なくなるため満足な初期接着
強度が得られない。そのため接着剤は粘着性樹脂固形分
濃度が少なくとも１０％以上でなけれはばならない。On the other hand, if the concentration of tackiness in the adhesive is too low, the amount of resin that adheres to the paper surface will be small, making it impossible to obtain a satisfactory initial adhesive strength. Therefore, the adhesive must have a solid concentration of adhesive resin of at least 10%.
接着剤が以上述べたような条件を満たすとき、紙へ塗布
し貼り合わせた後１５秒以内に０．１ｋｇ／ｃＪ以上の
瞬間接着性を示す。When the adhesive satisfies the conditions described above, it exhibits instantaneous adhesion of 0.1 kg/cJ or more within 15 seconds after being applied to paper and bonded together.

０．１〜２重量％である。The pigment may be any colored pigment such as red, blue, yellow, black, green, or purple, or may be a white pigment in the case of an adhesive used for colored paper. Although the amount added is arbitrary, it is generally 0.1 to 2% by weight in the adhesive liquid.
本発明の接着剤は着色されているので塗布面を明瞭に確
認でき、フェルトペン式塗布器具を使用して必要とする
面積のみへ正確に接着剤を塗布することができる。Since the adhesive of the present invention is colored, the surface to be applied can be clearly seen, and the adhesive can be applied accurately to only the required area using a felt-tip applicator.
