An ink-jet recording ink set includes: an ink (I) containing a dye D1, a compound C1 represented by the following formula and having a U+V of S1, and water; and an ink (II) containing a dye D2, a compound C2 represented by the following formula and having a U+V of S2, and water in which in case that a surface tension ³L1 (mN/m) of an evaluation liquid L1 obtained by adding, to a 5 mass% aqueous solution of the dye D1, a compound C3 in an amount corresponding to 1 mass% of the aqueous solution, and a surface tension ³L2 (mN/m) of an evaluation liquid L2 obtained by adding, to a 5 mass% aqueous solution of the dye D2, the compound C3 in an amount corresponding to 1 mass% of the aqueous solution satisfy a relationship of ³L1-³L2‰¥10 (mN/m), the S1 and the S2 satisfy a relationship of 2‰¤S2-S1‰¤7. |
