Abstract
Description
【発明の詳細な説明】 (産業上の利用分野) 本発明は、感熱紙に用いる字消し液に関する。[Detailed description of the invention] (Industrial application field) The present invention relates to an erasing liquid used for thermal paper.
(従来の技術)
近年ファクシミリ等の普及に従って感熱紙の使用が増大
しているが、感熱紙用の字消しは未だ開発されておらず
9文字等の修正には、砂字消や修正液が用いられていた
。(Prior art) In recent years, the use of thermal paper has increased with the spread of facsimiles, etc. However, a letter eraser for thermal paper has not yet been developed, and sand letter erasers or correction fluids are required to correct 9 characters etc. It was used.
(発明が解決しようとする問題点)
しかしながら、砂字消を用いた場合は9紙面が削り取ら
れる為、消字跡の美観が損なわれ。(Problem to be Solved by the Invention) However, when a sand eraser is used, nine parts of the paper are scraped off, which impairs the aesthetic appearance of the erased marks.
又修正液を用いた場合は、修正液と感熱紙−0色が大き
く異なる為、修正部分が強調されてしまい砂字消と同様
美観が損なわれるという問題点があった。Further, when a correction liquid is used, there is a problem that the correction liquid and the color of the thermal paper-0 are greatly different, so that the correction part is emphasized and the aesthetic appearance is spoiled, similar to sand letter erasing.
(問題点を解決するための手段)
そこで2本発明者等は、上記問題点を解決する為に鋭意
研究を行なった結果本発明を完成するに至った。(Means for Solving the Problems) Therefore, the two inventors conducted intensive research in order to solve the above problems, and as a result, they completed the present invention.

用量は字消し液全量に対して60〜90重量%である。To explain the present invention in more detail, polyethylene glycol is used as an erasing material for characters printed on thermal paper, and the amount used is 10 to 40% by weight based on the total amount of one character eraser. is preferred. As the main solvent, water and/or alcohol are preferably used, and the amount used is 60 to 90% by weight based on the total amount of the erasing liquid.
その他添加剤としては、浸透剤、防カビ剤等が適宜用い
られる。Other additives that may be used include penetrants, antifungal agents, and the like.

し、その結果文字等が消去されるものと推察する。(Function) I am not sure why polyethylene glycol erases characters, etc. on thermal paper, but it is inferred as follows. Thermal paper has a base paper coated with a leuco dye as an electron donating component and a coloring agent (mainly solid acid) as an electron accepting component, together with a binder, and the heat dissolves the leuco dye and the coloring agent chemically. The mechanism is to cause a reaction and develop color, and it is assumed that polyethylene glycol decomposes the bond between the scyloid dye and the coloring agent by some action, and as a result, characters, etc. are erased.
