等を硬、べい修正するための修正液に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention is a method for hardening and correcting handwriting with various writing instruments, printing by a typewriter, or copied images by a dry type electrophotographic copying machine. Regarding correction fluid.
従来、万年筆、水性サインペン等の水性インキによる誤
字の修正には油性型修正液が、油性ボールペン、油性マ
ーカー等の油性インキによる誤字の修正には水性型修正
液が、また、水性、油性を問わずどのタイプのインキに
対しても修正可能な万能型の修正液が知られている。Traditionally, oil-based correction fluid was used to correct typographical errors made with water-based ink such as fountain pens and water-based felt-tip pens, while water-based correction fluid was used to correct typographical errors made with oil-based ink such as oil-based ballpoint pens and oil-based markers. A universal correction fluid that can correct any type of ink is known.
これら修正液の中で、油性および水性型修正液は消去さ

いという不便さがあるのに対し、万能型のものは、イン
キの種類に左右されることなく、どのタイプのインキに
対しても修正可能である点で有利である。Among these correction fluids, oil-based and water-based correction fluids have the inconvenience of having to be used depending on the type of ink to be erased, whereas universal ones are sensitive to the type of ink. It is advantageous in that it can be corrected for any type of ink without any problems.
ところで、このような修正液に要求される性能としては

るが、従来知られている万能型修正液は、必ずしもこれ
らの要求性能の全てを十分満足し得るものであるとはい
い難い。By the way, the performance required for such a correction fluid is that there is no sedimentation or agglomeration of the pigments contained in it, that it has excellent stability over time, such as being unlikely to thicken, and that it dries quickly. The correction coating film that is formed completely hides letters, etc., and has excellent correction functions. However, conventionally known all-purpose correction fluids do not necessarily meet all of these required performances. It is difficult to say that it is completely satisfactory.

ている。For example, conventional all-purpose correction fluids are known to contain white pigments, halogenated hydrocarbon solvents, and petroleum resins; Although it has an excellent correction function for oil-based inks, it tends to be inferior in correction function for oil-based inks. There are problems.
上記毒性の問題点を改善するため、ハロゲン化炭化水素

たりするなどの問題点がある。In order to improve the above-mentioned toxicity problem, a correction fluid using methylcyclohexane instead of a halogenated hydrocarbon solvent is known, but methylcyclohexane has excellent solubility in petroleum resins. For this reason, it is difficult to
The correction fluid has problems such as thickening during storage or use, poor dispersion of the white pigment, and, in extreme cases, sedimentation or agglomeration.

いだして本発明を完成したものである。In view of the above-mentioned current situation, the inventors of the present invention have developed a versatile model 11! which has excellent stability over time and has a correction function equivalent to or better than conventional ones! As a result of extensive research to provide a corrective solution, we found that an acrylic resin with a specific composition showed good solubility in methylcyclohexane, resulting in extremely good pigment dispersion and thickening of the resulting correction fluid. The present invention was completed by discovering that no phenomenon or precipitation of pigments was observed.

(R3 and RA may be the same or different and each represents a methyl group or an ethyl group, and n represents an integer of 1 to 3). It is preferable to use titanium oxide such as rutile type or anatase type titanium oxide, which has a particularly high concealing property, as a component for concealing.
Titanium oxide that can be used is available on the market and is easily available by hand.
