る。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an inkjet recording ink, and particularly to an inkjet recording ink in which the ink is ejected by pushing the ink out of a nozzle due to a sudden drastic reduction in the internal volume of the container. This article relates to an aqueous ink composition.

いる。Conventionally, the ink used in this type of inkjet recording method is one that does not cause clogging in the nozzle like inks used in other inkjet recording methods;
It is important that the ink has sufficient contrast for recording, that physical properties do not change or precipitate during storage, and that the ink has appropriate viscosity and surface tension. It is recognized that

するとインクの圧力損失が生じ、インクが吐出さない。
又、泡のない状態インクを使用しても、応答周波数を上

が発生して来る等の問題がしばしば現われる。本発明は
、上記欠点に着目してなされたものである。Since a simple colorant-water system is insufficient for ink systems that satisfy these required characteristics, various substances are added. As is well known, a multi-component solution system tends to foam when it comes into contact with a gas such as air, and since a surfactant is added as an ink surface tension adjusting agent, foaming is further promoted. And foam due to addition of surfactant,
It has drawbacks such as difficulty in defoaming, and once it enters the ejection head, pressure loss occurs and the ink is not ejected.
Furthermore, even if bubble-free ink is used, as the response frequency is increased, problems such as bubbles often appearing due to the suction of air after ink droplets are ejected. The present invention has been made by focusing on the above-mentioned drawbacks.
即ち、従来要求特性を低下することなく、泡の発生を防

To explain in more detail, antifoaming agents (foam suppressants) that prevent the generation of foam include fatty acid esters, amines, phosphate esters, metal soaps, and silicone oils.

。Furthermore, when the above ink system and the above ink system without the addition of antifoaming agent aluminum stearate are placed in separate test tubes of 3 mι and shaken at the same time, the former shows almost no foam formation. On the other hand, a lot of foaming was observed in the latter case, and it took about 5 hours for the foam to disappear completely. As described above, the present invention provides an inkjet with modified nozzle ejection characteristics by preventing foaming without reducing other required characteristics of the ink and preventing the ejection characteristics from the nozzle. The present invention aims to provide a recording ink, and is particularly suitable for quick-drying ink containing a surfactant at a concentration higher than the micelle concentration.
