Abstract
The present invention relates to a liquid composition for forming a colored portion on a recording medium together with an anionic or cationic water-based ink containing a coloring material. The liquid composition comprises a solvent, fine particles in a dispersion state, wherein the fine particles have a surface charge in a polarity opposite to the water-based ink and has ion whose polarity is opposite to that of the fine particles in an ionic equivalence of 0.1-40 meq/l.
