Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an ink composition for inkjet recording, which shows a low viscosity despite of its high concentration of solid components, secures a high OD-value/fixability as one of printing characteristics and is capable of securing reliability in terms of recovery from clogging, high-temperature jetting stability, etc. SOLUTION: The ink composition for inkjet recording contains a self-dispersing pigment and two kinds of resin particles each having a glass transition temperature (Tg) of below 0°C, wherein the self-dispersing pigment and the two kinds of the resin particles are contained as solid components and account for ≥10 wt.% in total. The two kinds of resin particles both have OH groups within the molecule and share a common skeleton. The ink composition for inkjet recording further contains both an inorganic alkali and an organic alkali. COPYRIGHT: (C)2007,JPO&INPIT
