摘要： An ink jet recording ink composition comprising, as indispensable components, a coloring component and a dispersion medium for maintaining the coloring component in a homogeneously dispersed state, characterized in that the coloring component is insoluble in the dispersion medium and dispersed in a particulate form in the dispersion medium, the particle diameter is 0.01 νm or more, the dispersion medium comprises a liquid having a surface tension of 50 dyn/cm or less at 25 °C and the dispersion medium separates from the coloring component as soon as the ink composition deposits on a recording material. This composition brings about no blotting and exhibits an excellent printing quality.
