The present invention provides an ink set that can provide a high-quality printed matter with excellent print density and little show-through, and an ink set that is excellent in material compatibility of an inkjet print head and has little pH change during storage. And a liquid composition contained in the ink jet recording method. [1] An ink set for ink jet recording comprising a water-based ink containing an anionic colorant and a liquid composition, wherein the liquid composition comprises a cationic polymer, a water-soluble organic solvent, an acid dissociation index ( pKa) contains an acid with 2-6, and an organic amine with a base dissociation index (pKb) of 3-8, does not contain an acid with a pKa less than 2, or contains less than 0.5% by weight, and its pH is 7 to 9, an ink set for ink jet recording, [2] a liquid composition contained in the ink set for ink jet recording, and [3] an anionic property after adhering the liquid composition to a recording medium by an ink jet method This is an ink jet recording method in which recording is performed by an ink jet recording method using a water-based ink containing a colorant.
