式の修正筆記具にも対応できる修正液に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a correction liquid for erasing and correcting written characters, printed characters, copied characters, and the like. Further, the present invention relates to a correction liquid that can be used not only with current correction writing instruments but also with ballpoint pen-type correction writing tools.

【従来の技術】 現行の修正液の粘度は、例えばアクリ
ル樹脂を用いた場合の修正液の粘度は通常１００センチ
ポイズ以下が好ましく、というのは現行の修正筆記具の
構造上、これ以上粘度が高いと修正液が出にくくなると
いう必然性があった。2. Description of the Related Art The viscosity of a current correction fluid, for example, when using an acrylic resin, the viscosity of the correction fluid is usually preferably 100 centipoise or less. There was a necessity that the correction fluid was difficult to come out.

【発明が解決しようとしている課題】 現行の修正液に
使用される溶剤はメチルシクロヘキサン（ＭＣＨ）であ

この樹脂をＭＣＨに溶解して作った修正液の粘度を高く
するために、超微粒子酸化物を加えて、例えば１０００
センチポイズの粘度の修正液を得たとしても、修正液の
膜強度と隠蔽性との両立した好ましい状態は得られな
い。この現象は、ゴム系以外の樹脂の必然性であり、つ
まり、樹脂の柔軟性と顔料との相溶性とにおいて劣って
いるためである。The solvent used for the current correction fluid is methylcyclohexane (MCH), but in the case of a resin other than a rubber-based resin, for example, an acrylic resin,
In order to increase the viscosity of the correction fluid prepared by dissolving this resin in MCH, ultrafine oxide particles are added, for example, 1000
Even if a correction liquid having a viscosity of centipoise is obtained, a favorable state in which the film strength and the concealing property of the correction liquid are compatible cannot be obtained. This phenomenon is inevitable for resins other than rubber-based resins, that is, the flexibility of the resin and the compatibility with the pigment are inferior.

柔軟性を保つのである。従って、ゴム系の樹脂を使って
作成した修正液に、粘度を高くするために超微細金属酸
化物を配合しても十分な膜強度と柔軟性を失わない。Means for Solving the Problems A rubber-based resin is very flexible as compared with other resins, and does not lose its flexibility even when a large amount of a solid such as a pigment is blended. That is, as compared with other resins, the strength and flexibility of the film are maintained even in the state of a high pigment volume concentration. Therefore, even if an ultrafine metal oxide is blended with a correction fluid prepared using a rubber-based resin to increase the viscosity, sufficient film strength and flexibility are not lost.
【０００５】 樹脂に対して多くの固体成分を配合した
修正液の隠蔽性は、当然高く好ましい。従って、ゴム系
の樹脂を使って作成した修正液は隠蔽性に優れ、薄い膜
厚で修正可能となる。このことはボールペンのようにイ
ンキの出の少ない場合には、特に有利となる。[0005] The concealing property of a correction liquid in which many solid components are blended with a resin is naturally high and preferable. Therefore, a correction liquid prepared using a rubber-based resin has excellent concealing properties and can be corrected with a thin film thickness. This is particularly advantageous when the amount of ink discharged is small as in a ballpoint pen.

い粘度に調整して得られる。[0006] The correction liquid in the present invention is prepared by adding an appropriate dispersant and a solid component such as a pigment to an MCH solution of a rubber-based resin and dispersing the same, and then adding an ultrafine metal oxide thereto to adjust the viscosity to a preferable value. Obtained.

どがある。The rubber-based resin that can be used in the present invention must be soluble in the solvent used (generally, methylcyclohexane). For example, styrene-butadiene rubber, butyl rubber, polybutadiene rubber, nitrile rubber and so on.

樹脂を成型して球状にしたものが好都合である。一例を
挙げると日本触媒化学製のエポスターＭＳである。In the present invention, it is not necessary to use titanium oxide as a solid component that determines the concealing property of the correction liquid. This is very advantageous because of the high pigment volume concentration as described above. Of course, use of titanium oxide is not a problem. As the solid component used in the present invention, a resin obtained by molding a resin having a particle size in the range of 0.5 to 10 μm into a spherical shape is convenient. An example is Eposter MS manufactured by Nippon Shokubai Chemical.
