[PROBLEMS] To provide an ink set comprising a treatment liquid and an inkjet ink composition, capable of satisfactorily reducing banding unevenness and having good ink storage stability. One aspect of the ink set according to the present invention is an ink set comprising a treatment liquid containing a flocculant and an inkjet ink composition, which is suitable for recording on a low-absorption or non-absorption recording medium. The inkjet ink composition comprises a coloring material, a water-soluble organic compound having a solubility of more than 10 g in 100 g of water at 20°C, and a diluent having a solubility of 0.1 to 10 g in 100 g of water at 20°C. A water-based ink containing a water-soluble organic compound, wherein the slightly water-soluble organic compound has a normal boiling point of 180 to 300° C., diols or glycol ethers in an amount of 2 per total mass of the ink composition. .3% by mass or less.
