ABSTRACT:
Disclosed is an ink composition that, while improving print quality, advantageously has excellent ink ejection stability and does not significantly erode members such as a head and, at the same time, can meet a recent demand for highly skillful printing conditions, for example, high-speed printing with very small amounts of droplets. Ink jet recording is carried out using an ink composition comprising an acetylene glycol, an alcohol adduct of ethylene oxide and/or propylene oxide, and a pyrrolidone or its derivative in a specific composition.
