本発明は、万年筆、水性サインペンなどの水性インキの
筆跡１通常のボールペンの筆跡、タイプライタ−の印字

られるようなした修正液に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a correction fluid for correcting obscuring handwriting of water-based ink such as fountain pens and water-based felt-tip pens, handwriting of ordinary ballpoint pens, printing of typewriters, etc. The present invention relates to a correction fluid that allows a correction coating film to dry well and to provide a flexible correction coating film.
従来、水性インキの墓跡、ボールペンの筆跡。Traditionally, water-based ink marks, ballpoint pen handwriting.
タイプライタ−の印字の隠蔽修正用修正液としては、ア
クリル系樹脂を使用したものが知られているが、修正塗

ラックが発生し、塗膜が剥離するという問題があり、こ
の問題を解決するために可塑剤を添加していた。As a correction fluid for concealing and correcting typewriter prints, there is one that uses acrylic resin, but although the correction coating is uniform, the coating is hard and the corrected paper may be folded away from the corrected area. When dried, cracks occur in the paint film along the creases, causing the paint film to peel off. To solve this problem, plasticizers have been added.
然し乍ら、可塑剤を添加した修正液は、その修正した個

じかれてし１い、再筆記した筆跡が不明瞭となってし甘
うという新た庁問題が生じていた。However, if a correction fluid containing plasticizer is used to rewrite the corrected area with water-based ink, the water-based ink will be repelled and the rewritten handwriting will become unclear. A new agency problem arose.
更には従来の溶剤は、トルエン、キルンなどの芳香族系
炭化水素が使用されており、塗膜の乾燥が遅く、印字ス
ピードが“要求されるタイプライタ−の印字の修正には
好寸゛シ〈ないものであった。Furthermore, conventional solvents use aromatic hydrocarbons such as toluene and kiln, which dry the paint film slowly and are not suitable for correcting typewriter printing, which requires high printing speed. <It was something that didn't exist.
そこで、木発明者等は、修正塗膜の乾燥が良好であり、

のである。Therefore, the inventors of the tree discovered that the correction coating film dries well,
A resin, which is an essential component of the correction liquid, is used to obtain a correction liquid that can provide a flexible correction coating film without using a plasticizer.
As a result of various studies regarding solvents, the present invention was finally completed.

。That is, 1 the present invention has a copolymerization ratio of vinyl acetate of 40 to 9Qi.
The gist is ethylene-vinyl acetate copolymer resin as a background agent, 1,Lj-trichloroethane as a chlorinated hydrocarbon solvent, and at least a correction fluid made of titanium white.
以下１本発明の詳細な説明する。Hereinafter, one aspect of the present invention will be explained in detail.
本発明で特に重要なことは、エチレン酢酸ビニル共重合
樹脂（以下Ｅ Ｖ Ａと略す）のうち。Particularly important in the present invention is ethylene vinyl acetate copolymer resin (hereinafter abbreviated as EVA).
酢酸ビニル（以下Ｖ Ａ Ｃと略す）共重合比率４０〜
９０重量係のＥ Ｖ Ａを使用することにある。Vinyl acetate (hereinafter abbreviated as VAC) copolymerization ratio 40~
The purpose is to use EVA with a weight rating of 90%.

で修正液の樹脂として好適なものがＶＡｃが４０〜９０
重量係であることを見い出した。After various inspection and machining, '1. Li-) A resin that is soluble in lychloroethane and suitable as a correction fluid resin has a VAc of 40 to 90.
I found out that it was a weight clerk.
Ｅ １１ Ａは一般Ｋ Ｖ Ａ ｃ共重合比率が増大す
るに従って溶剤に対する溶解性も増太し、又、溶解粘度
が低下する傾向にある。As the general K V Ac copolymerization ratio increases, the solubility of E 11 A in solvents increases, and the solution viscosity tends to decrease.
又、ＶＡｃが２５重量係以下のＥＶＡＩ−ｊ。Also, EVAI-j with a VAc of 25 weight coefficient or less.
ｉ、ｉ、＋−トリクロルエタンにゲル化もしくは白ン蜀
する傾向にある。It tends to gel or turn white into i,i,+-trichloroethane.
特に、修正液の塗布性能は修正液の粘度が低い方が良好

ｃが４Ｑｉ量係以上のＥ Ｖ Ａが使用でき、又＋ Ｖ
Ａ、 ｃが９ｏ重量％以上、ではゴム的性質を損なう
。In particular, since the coating performance of the correction fluid is better when the viscosity of the correction fluid is lower, "l'A" is used as a resin for the repair IF fluid.
E V A with c of 4 Qi or more can be used, and + V
If A or c exceeds 90% by weight, the rubbery properties will be impaired.

１０〜２５℃の物性値を示し、ゴム的々性状を示すため
、修正塗膜の屈曲性にも優れているものと思われる。EVA fi within the range of V A c described above, crystallinity of about 5 to 0%, elongation of about 400 to 2500, rough secondary transition point of about 10 to 25 ° C, and exhibits various rubber properties. Therefore, it is thought that the modified coating film also has excellent flexibility.
