The present invention provides an ink and an ink jet method using the ink, which provide a recorded matter in which unevenness in density is suppressed when printing at a high density. An ink containing a coloring material, water, a resin emulsion, an organic solvent containing 2-pyrrolidones and diols, and a silicone surfactant, wherein the boiling point of the diols is 200 ° C. or more and 230 ° C. or less, and the ink contains 10% by mass or less of the diols and 2.0% by mass or more of the silicone-based surfactant with respect to the total amount of the ink. And an ink containing 5.0% by mass or more of the resin emulsion, and the SP value of the silicone surfactant is less than 13. [Selection figure] None |
