    摘要： An ink for ink jet recording satisfying the following requirements (A) and (B) possesses excellent color development and moisture resistance. (A) A color difference E of 9 or less as judged by a method comprising the following steps (1) to (3). (1) The step of applying an ink containing a colorant, water, and a water soluble organic solvent, which has a lower evaporative rate X than water, has a moisture absorption Y (mass%) of not less than 20 and satisfies Y ≥ 2.8X + 10, and then superimposing an ink having the same composition as the above ink except for the use of water instead of the colorant. (2) The step of allowing the record to stand under the first and second conditions. (3) The step of judging the record in terms of a color difference (ΔE) represented by formula (1): wherein L1, a1 and b1 represent L, a and b of Lab color system before the second standing; and L2, a2 and b2 represent L, a and b of Lab color system after the second standing. (B) A content of the water soluble organic solvent satisfying Y ≤ 2.8X + 10 of not less than 50% by mass.
