PROBLEM TO BE SOLVED: To obtain a colored microparticle-dispersed system excellent in various characteristics including handleability, smell, safety, colored microparticle dispersion stability and the color developability/color tone of prints when printed on any selected sheet of paper with no paper dependency. SOLUTION: This colored microparticle-dispersed system is obtained by dispersing colored microparticles comprising an ionic group-containing polymer, an oil-soluble dye and a hydrophobic high-boiling organic solvent of >=150 deg.C in boiling point in an aqueous medium; wherein the content of the hydrophobic high-boiling organic solvent in the system is characterized by being 25-95 mass% based on the sum total of the ionic group-containing polymer, oil-soluble dye and the hydrophobic high-boiling-organic solvent, and preferably, the oil-soluble dye is characterized by being shown by general formula (I). |
