剤中に分散するための分散剤よりなっている。(Prior Art) Conventionally, commercially available correction fluids consist of a pigment for concealing typographical errors, a film-forming resin that acts as a binder for the pigment, a solvent for dissolving the resin, and the pigment in a solvent. It consists of a dispersant for dispersion.

This is a correction fluid (Japanese Patent Publication No. 6L-36552) that uses cellulose ether resin as a concealing agent binder and dissolves and disperses it using a chlorine-based organic solvent. Correction liquid obtained by dispersing a masking agent during polymerization in a mixed solvent system of hydrocarbon and chlorinated organic solvent (Special Publication)-5

点を有する。As mentioned above, water-based correction fluids and oil-based correction fluids have the disadvantage that the writing lines that can be corrected are limited, but water-based and oil-based correction fluids eliminate the above-mentioned drawbacks and can correct the writing lines of oil-based inks. It also has the advantage of being able to correct both lines written with water-based ink.

いう欠点があった。However, recently, office automation equipment such as reflective copying machines and fax machines have come into use in offices and the like. Incidentally, when copying is performed using a reflective copying machine, the toner contains styrene resin, and when using a fax machine, capsules of a coloring agent are present on the surface of heat-sensitive press paper. When correcting writing lines on copied paper or heat-sensitive and pressure-sensitive paper, if you use the common water-based and oil-based type described above, the corrected surface will darken because it will dissolve the styrene resin and coloring agent capsules in the toner. The drawback was that correction concealment could not be performed completely.
（発明が解決しようとする課題）
本発明者は、従来の水性油性共用タイプの特徴点を保持

である。That is, in the present invention, all the solvents used are thickening agents (good solvents) for the resin that maintains the dispersion stability of the correction fluid, so while the dispersion stability of the correction fluid can be maintained well, the solvent used is Since it does not dissolve the styrene resin contained in the toner of reflective copying machines or the coloring agent capsules on the surface of the heat-sensitive and pressure-sensitive paper, there is no drawback such as darkening of the corrected surface. It goes without saying that it is possible to correct and hide the writing lines of ordinary writing instruments.

性を極めて良好な状態に保つことができる。(Function) According to the present invention, the resin used to maintain dispersion stability is soluble in a paraffinic solvent that does not dissolve the styrene resin in the toner or the color former capsule on the surface of the heat-sensitive and pressure-sensitive paper. The dispersion stability of the correction fluid can be maintained sufficiently. Even if the concentration becomes localized due to the gravity of the hiding agent inside the solution due to long-term standing, the solvent used is a rich solvent for the resin used in the correction solution, so it can be easily dispersed uniformly by applying external force. As a result, the dispersion stability of the correction fluid can be maintained in an extremely good state.

える。On the other hand, the solvent that makes up the correction fluid does not dissolve not only ordinary water-based and oil-based inks, but also the styrene resin in toner used for copying, or the coloring agent capsules on the surface of heat-sensitive and pressure-sensitive paper. It can correct and hide written lines, making it a truly versatile correction fluid.

The mixture was dispersed and mixed for 4 hours. Regarding the obtained samples, facsimile manuscripts and reflective copy manuscripts (PPC) were corrected using a brush, and those in which discoloration or color bleeding was observed were marked as x, and those in which the correction was successful (effects of the invention). As shown in the performance comparison of Examples and Comparative Examples, according to the present invention, while maintaining a high degree of dispersion stability of the correction fluid, it is possible to correct not only normal writing lines of water-based and oil-based inks, but also facsimile or PPC. It is possible to obtain a truly all-purpose correction fluid that can completely correct manuscripts.
