【発明の詳細な説明】
（産業上の利用分野）
本発明はインクジェット記録液（以下インクという）及
びインクジェット記録方法に関し、紙、樹脂フイルム等
の被記録材に安定的に画像形成が可能なインクジェット
インク及びインクジェット記録方法に関する．
（従来の技術）
インクジェット記録方法は、種々のインク吐出方式によ

一部又は全部を紙等の被記録材に付着させて記録を行う
方式である。Detailed Description of the Invention (Industrial Application Field) The present invention relates to an inkjet recording liquid (hereinafter referred to as ink) and an inkjet recording method, and relates to an inkjet recording liquid that can stably form images on recording materials such as paper and resin films. Concerning ink and inkjet recording methods. (Prior Art) An inkjet recording method is a method in which ink droplets are formed using various ink ejection methods, and some or all of them are attached to a recording material such as paper to perform recording. .
この様なインクジェット記録方式に使用するインクとし
ては、記録剤（染料又は顔料が用いられる）及びこれを
溶解又は分散する液媒体（水又は各種有機溶剤或いはこ
れらの混合物が用いられる）を基本的成分とし、又、必
要に応じて各種添加剤が添加されたものが知られ且つ使
用されている。The basic components of the ink used in such inkjet recording methods are a recording agent (dye or pigment is used) and a liquid medium for dissolving or dispersing it (water, various organic solvents, or a mixture thereof is used). In addition, products to which various additives are added as necessary are known and used.
（発明が解決しようとしている問題点）上記の如き従来
のインクにおいては種々の性能が要求されるのは当然で
あるが、なかでも熱エネルギーを作用させて行うインク
ジェット記録用インクにおいて最も要求される性能は、
インクを用いて記録を行っている際、温度変化によって
発熱ヘッドの表面に異物の沈着が無いという液安定性で
ある．しかしながら、従来のインクの場合には長時間の
吐出を行うと、発熱ヘッドの表面に異物が沈着し，イン
クの吐出が停止してしまうという問題点があった。(Problem to be solved by the invention) It is natural that conventional inks such as those mentioned above are required to have various performances, but among them, inkjet recording inks that use thermal energy are most required. The performance is
The liquid stability means that when recording with ink, no foreign matter is deposited on the surface of the heat-generating head due to temperature changes. However, in the case of conventional ink, there is a problem in that when ejecting for a long time, foreign matter is deposited on the surface of the heat generating head, causing ink ejection to stop.

(Function) According to detailed research by the present inventor, heat generation occurs during inkjet recording. Recognizing that the biggest cause of foreign matter depositing on the surface of the head is the presence of divalent or higher valent metal ions contained in the ink, we can react with these metal ions to increase dissolution stability and further It has been found that long-term inkjet recording becomes possible by incorporating a small amount of polyphosphonic acid or its salt into the ink as an additive that increases the thermal stability on the exothermic heater.
