ある。Detailed Description of the Invention [Summary] The present invention aims to solve the problem of nozzle clogging caused by ink in an inkjet recording device by gelling the ink (by removing the solvent from it) when the recording device is not powered on. This suppresses evaporation, crystallization of dyes, and precipitation of inorganic salts.
本発明は、ノズルの目詰まりを生じさせないインクジェ
ット記録用インクに関する。The present invention relates to an inkjet recording ink that does not cause nozzle clogging.

クが要望されている。Inkjet recording devices have low noise, low running costs, and can be easily printed in color, and have recently been attracting attention both domestically and internationally as office automation printers. Therefore, it is necessary for such a recording apparatus to prevent nozzle clogging during long-term use, and there is a demand for ink that is less likely to become clogged.

あった。However, such conventional inks are liquid at room temperature, and evaporation of the solvent, crystallization of the dye, and precipitation of inorganic salts progress over time, and unless measures such as cleaning the nozzle from time to time are taken, the nozzle eyelids will be damaged. There was a drawback that clogging occurred.
このような欠点は印字欠落を生じ、装置の信頼性を損う
原因となる。Such defects cause missing prints and impair the reliability of the device.
本発明は、このような従来の欠点に鑑みてなされたもの

以下、本発明について実施例を上げて説明する。The ink according to the present invention greatly suppresses gel state cauterization, solvent evaporation, dye crystallization, and inorganic salt precipitation when the recording device is not in operation, thereby preventing the occurrence of nozzle clogging. [Examples] The present invention will be described below with reference to Examples.
本発明の一実施例のインク組成は下記のごとくである。The ink composition of one embodiment of the present invention is as follows.
