(57) [Summary] [Problem] Excellent color reproducibility, transparency and glossiness of printing, An ink composition that is excellent in water resistance and image storage stability, is excellent in image glossiness, image fastness such as ozone storage resistance, and has improved scratch resistance when combined with an image receiving material, and the ink composition An ink jet recording method using the object is provided. SOLUTION: A hydrophobic dye, a hydrophobic polymer, a high-boiling organic solvent having a water solubility of 4 g or less, and a boiling point of 20 A colored fine particle containing a solution containing an auxiliary solvent having a solubility in water of 25 g or less, and an aqueous medium mixed with an aqueous medium, and colored fine particles obtained by removing the auxiliary solvent after emulsification and dispersion. The average particle size of 0.01 to 0.5 μm The particle diameter variation coefficient is within 45% and the specific gravity is 0.9 to On the ink composition that is 1.2, and the ink receiving material, After forming an image by landing the ink composition, In the ink jet recording method, the colored fine particles are heat-treated and / or pressurized and the colored fine particles are fused. |
