ことができる。Inkjet printers are currently attracting attention as non-impact printers, but their printing system is
Printing can be accomplished by pressurizing the fluid ink to separate it from a 50-150 um nozzle orifice into ink droplets, which are then ejected onto recording paper as needed.
一方、インク式ワイヤドツトプリンタは、ドツトプリン

記録紙に転写することにより印刷するシステムである０
両者いずれも、流体インクを用いるため、記録ヘッドへ
のインク供給方法など共通する点が多い、従って問題点
の共通する点が多く、インクで必要とされる要件は、次
の事柄が挙げられる。On the other hand, an ink-type wire dot printer is a system that prints by attaching ink to the wire of the dot printer and transferring the ink on the wire surface to recording paper.
Since both use fluid ink, they have many things in common, such as the method of supplying ink to the recording head.Therefore, they have many problems in common, and the requirements for the ink include the following.
（１）インクが記録ヘッドノズルにおいて目詰りをしな
いこと。(1) Ink does not clog the recording head nozzles.
（２）インクが記録紙に転写された時、迅速に乾燥する
こと。(2) When the ink is transferred to the recording paper, it dries quickly.
（３） インクが温度変化により凝固して、インク中
に気泡を発生しないこと。(3) The ink should not solidify due to temperature changes and bubbles should not be generated in the ink.
（４）インクが長期にわたり変質を起こさず、貯蔵性が
よいこと。(4) The ink does not deteriorate over a long period of time and has good storage properties.
（５） インクがガラスや金属を腐食しないこと。(5) The ink should not corrode glass or metal.
（６）インクの濃度が大きく紙に転写されたとき、ドツ
トの円形度、コントラストが明確であること。(6) When the ink has a high density and is transferred to paper, the circularity and contrast of the dots should be clear.
以上がインクジェットプリンタおよびインク式ワイヤド
ツトプリンタに要求されるインクの要件であるが、これ
らは前記（１）、（２）のようにお互いに相反する性質
があり、これらすべてを満足するインクをつくることは
非常に難しいことであった。The above are the requirements for ink for inkjet printers and ink-type wire dot printers, but these have mutually contradictory properties as described in (1) and (2) above, and it is difficult to create ink that satisfies all of them. was extremely difficult.
本発明の目的は、前記インク要件をすべて満足するイン
クジェットプリンタ、インク式ワイヤドツトプリンタに
適するインクを提供することにある。An object of the present invention is to provide an ink suitable for inkjet printers and ink-type wire dot printers that satisfies all of the above ink requirements.
従来のインクジェットプリンタ用インクは、はとんどが
水溶性インクであり、該インクの構成は゛染料、湿潤剤

インダーの役割を果し、乾燥によるノズルの目詰りを防
止している。その反面記録紙に転写後のインクの速乾性
はなく、速乾性を出す場合には前記系に界面活性剤を添
加し、インクの表面張力を低下させ記録紙に浸透させる
ことにより速乾性をだす方法が用いられている。しかし
、この方法によると、前記インク要件（６）のドラトノ
円形度が、紙の繊維のにじみのため出せない欠点がある
。また、水溶性インクのほとんどは凝固点が一１０℃以
上のため、凍結による気泡の発生がインク中に起こり、
インクジェットプリンタの場合、気泡の存在によりイン
クの圧力が伝播されず、印刷不能となる。Conventional ink for inkjet printers is mostly water-soluble ink, which consists of a dye, a wetting agent, and water. In this system, the wetting agent acts as a binder for the dye. This prevents nozzle clogging due to drying. On the other hand, the ink does not dry quickly after being transferred to the recording paper, and in order to achieve quick drying, a surfactant is added to the system to reduce the surface tension of the ink and allow it to permeate into the recording paper. method is used. However, this method has the disadvantage that the circularity of the ink requirement (6) cannot be achieved due to bleeding of paper fibers. In addition, most water-soluble inks have a freezing point of 110°C or higher, which causes air bubbles to form in the ink due to freezing.
In the case of an inkjet printer, the presence of air bubbles prevents ink pressure from being propagated, making printing impossible.

油溶染料の中でもモノアゾ系の染料は本発明に用いるイ
ンクに適しており、有機溶剤に対する溶融性が優れてい
る。Among oil-soluble dyes, monoazo dyes are suitable for the ink used in the present invention, and have excellent solubility in organic solvents.
本発明のインクの組成としては、油溶染料２〜３０部（
重量部）を有機溶剤に溶解したものが好ましい。前記有
機溶剤の数種類の混合物を溶媒としていることも可能で
ある。The composition of the ink of the present invention includes 2 to 30 parts of oil-soluble dye (
Parts by weight) are preferably dissolved in an organic solvent. It is also possible to use a mixture of several types of the above-mentioned organic solvents as the solvent.
本発明のインクは、常温でそれ自体揮発が遅い溶剤から
成るため、ノズル部の目詰りはほとんど起らない。また
、凝固点も有機溶剤自体の融点が一３０℃以下であるた
め、それ以下になると考えてよいから、凝固による気泡
の発生は起らない。Since the ink of the present invention is composed of a solvent that itself evaporates slowly at room temperature, nozzle clogging hardly occurs. Further, since the melting point of the organic solvent itself is 130° C. or lower, it can be considered that the solidification point is lower than that, so that no bubbles are generated due to solidification.

かも、浸透が瞬時におこることにより、見かけ上のイン
クの速乾性力ぐでてきて、印刷−秒後に印刷物に触れて
も、紙がよごれることはなかった。In fact, when the ink of the present invention was used in an inkjet printer, printing was possible even if the hend filled with ink was left for about 3 days. In addition, oil-based inks have been generally thought to be inferior in print quality, such as the circularity of dots, because they penetrate quickly into recording paper, but with the ink of the present invention, penetration into recording paper is instantaneous. Excellent circular dots were obtained with less buildup and paper fibers. Furthermore, the instantaneous penetration caused the ink to dry quickly, and the paper did not become stained even if the printed material was touched seconds after printing.
インク式ワイヤドツトプリンタに本発明のインクを用い
た場合も、前記インクジェットプリンタと同様の効果が
得られ、しかもワイヤーなどの金属部分を腐食すること
なく、潤滑油としての効果もあるため、本発明のインク
は非常に有効である。When the ink of the present invention is used in an ink-type wire dot printer, the same effects as those of the inkjet printer described above can be obtained, and in addition, it does not corrode metal parts such as wires and has the effect of lubricating oil. Ink is very effective.
本発明のインクの貯蔵性に関しては、該インクを構成す
る系が安定性の高い有機溶剤であるため直射日光をさけ
るなど薬品の最低限の保守を行えば、数年に渡る貯蔵に
おいても変質は起こらない。Regarding the storability of the ink of the present invention, since the system constituting the ink is a highly stable organic solvent, it will not change in quality even after several years of storage as long as the chemicals are maintained at a minimum level, such as by avoiding direct sunlight. It won't happen.
