An ink jet recording liquid of high optical density, good rub resistance, and excellent feathering and long-term preservation stability when the liquid is used for printing on plain paper is used in an ink jet recording method. In the ink jet recording liquid which contains a pigment, water soluble organic solvent, and water as the essential components, and additionally containing water soluble resin and/or surfactant, 1) the temporal change rate of dynamic contact angle on plain paper is in a range from 0.5 to 3.5 degrees/second, 2) the number average particle diameter in the ink jet recording liquid is in a range from 15 to 100 nm, and 3) the volume average particle diameter in the ink jet recording liquid is in a range from 30 to 200 nm. The above-mentioned ink jet recording liquid is printed by means of ink jet recording. |
