<P>PROBLEM TO BE SOLVED: To provide an ink for inkjet recording being excellent in a coloring property, injection stability and a printing quality, preventing elution of a compound derived from a rubber member or the like in an inkjet recording apparatus into the ink, and being also excellent in stiffness. <P>SOLUTION: The ink for inkjet recording contains a dye (1), C.I. acid red 289 (AR289), water, dipropylene glycol propyl ether (DPP), and a specific acetylene glycol based surfactant. The dye (1), AR289, DPP and the surfactant are formulated so as to satisfy the conditions of (A)-(D). (A) A total formulation amount of the dye (1) and AR289 is 2-5 wt.% relative to the whole amount of the ink, (B) in the ink, the dye (1): AR289=9:1-7:3 (weight ratio), (C) 0.5≤x≤2.5, and (D) 1≤y≤3, x: a formulation amount (wt.%) of the surfactant of a specific structure relative to the whole amount of the ink, and y: a formulation amount (wt.%) of DPP relative to the whole amount of the ink. <P>COPYRIGHT: (C)2009,JPO&INPIT |
