などなどの条件を満たすことが必要であり、ロイコ染料
とフェノール性酸性物質が選定されて使用されている。Next, thermal paper can produce high-density records at low temperatures.
Leuco dyes and phenolic acidic substances have been selected and used because they must satisfy conditions such as uniform color development and excellent storage stability under high temperature and humidity.
さて本発明に係る感熱紙はこのように熱エネルギーの附
与により化学的変化を生ずるタイプであり、一度発色す
ると安定に存在し消去てないと云う特徴がある。The thermal paper according to the present invention is of a type that undergoes a chemical change when thermal energy is applied, and once a color develops, it remains stable and does not disappear.
このことは間違って印字した場合或いは訂正したい場合
も除去できないと云うことであり、今まで印字を消去す
る方法は見出されていない。This means that it cannot be removed even if it has been printed incorrectly or if it is desired to be corrected, and no method has been found to date to erase the printing.
ｆｄ）発明の目的

変化において消色する原因を究明した結果として見出さ
れたものである。(f) Embodiments of the Invention The present invention was discovered as a result of investigating the cause of symbols printed by a thermal printer method becoming discolored over time.
現在大量のデータを正確かつ効率よく電算機処理する方
法としてバーコードシステムが考案され商品などの流通
業界に用いられている。Currently, barcode systems have been devised as a method for accurately and efficiently processing large amounts of data using computers, and are being used in the product distribution industry.
すなわち黒バー、自バーおよびマージンで構成されるモ
ジュールを構成単位とし何桁かの数字で表現しである情
報をバーコードで記録しこれを光学的自動読取り装置を
用いて読取り電算機処理するものである。In other words, a module consisting of a black bar, a self-bar, and a margin is used as a structural unit, and information expressed as a number of digits is recorded in a bar code, which is read and processed by a computer using an automatic optical reader. It is.
そのため商品或いは製品の一部にバーコードラベルが貼
付されているがサーマルプリンタで印刷され商品上に貼
付されたバーコードラベルの内環化ビニール製品上に貼
付されたものは消色が起こり易い。発明者はこの原因を
調査した結果塩化ビニール中に可塑材として添加されて
いるフタル酸ジブチルが）ξみ出し、これにより消色が
起こることを見出した。Therefore, if a barcode label is attached to a product or a part of the product, the barcode label printed with a thermal printer and attached to the product is likely to fade if it is attached to the inner cylindrical vinyl product. The inventor investigated the cause of this and found that dibutyl phthalate, which is added as a plasticizer to vinyl chloride, oozes out, causing discoloration.
すなわちフタル酸ジブチルは凝固点−３５（’ｃ）沸点
が３３９（”Ｃ）で常温では液体であり、有機溶媒に可
溶で各種のビニール系およびセルローズ系の樹脂と相溶

そこでフタル酸ジブチルの作用を逆に利用しサーマルプ
リンタで打ち出された印字に塗布すれば印字を消去する
ことが可能となる。Therefore, by utilizing the effect of dibutyl phthalate and applying it to the print made by a thermal printer, it becomes possible to erase the print.
この消色の理由は明らかではないが恐らく（１）式で示
される極性化或いはイオン化した反応生成物にフタル酸
ジブチルを加えるとこれが消滅する結果、消色が起こる
と考えられる。The reason for this discoloration is not clear, but it is thought that the discoloration occurs as a result of the addition of dibutyl phthalate to the polarized or ionized reaction product represented by formula (1), which disappears.
なお消去液として用いる場合は常温で液体であるフタル
酸ジブチルをそのまま用いる。When used as an erasing liquid, dibutyl phthalate, which is liquid at room temperature, is used as is.
