Abstract: An ink−jet recording liquid containing a dye and a pigment. It has excellent dispersion and has satisfactory suitability for printing and storage stability. The ink−jet recording liquid comprises an aqueous medium and incorporated therein a pigment, a dye, and a surfactant, and is characterized in that (1) the pigment and dye at least partly comprise a pigment and a dye reversibly adsorbed thereon without involving a chemical reaction, (2) the dye reversibly adsorbed on the pigment without involving a chemical reaction comprises one having a dye adsorption shown by the following equation (I) of 0.02 g/g or more, and (3) the surfactant comprises a combination of a nonionic surfactant and an anionic surfactant.
