Abstract: An ink for ink-jet recording is provided, which makes it possible to obtain vivid recorded matters by satisfying both of the prevention of the feathering and the prevention of the bleeding even when the recording is performed on regular paper. The ink for ink-jet recording contains a self-dispersing type microparticulate coloring agent, a surfactant, and water. When the surface tension is plotted in the vertical axis, and the concentration of the surfactant is plotted in the horizontal axis, then the correlation between the surface tension and the concentration of the surfactant can be represented by a correlation curve which has one inflection point and which has two local maximum points of curvature on both sides of the inflection point one by one. Further, the ink for ink-jet recording contains the surfactant at a concentration which is higher than a concentration corresponding to the local maximum point of the curvature on the low concentration side.
