PROBLEM TO BE SOLVED: To provide an inkjet recoding ink suitable for a thermal, piezoelectric, electric field or acoustic inkjet system, having excellent handleability, smell and safety, excellent dispersion and storage stabilities, little in the clogging of a nozzle chip, free from paper dependency, excellent in color developing properties, especially color tone (hue) when printed on an arbitrarily selected paper, excellent in the permeability of the ink into a photographic image quality paper, excellent in water resistance, especially light resistance, and abrasion resistance after printing, and capable of recording an image in high density and high quality. SOLUTION: The inkjet recording ink comprises at least water, a water-soluble organic solvent and a dispersion of colored fine particles. The dispersion of colored fine particles contains a water-insoluble coloring agent and a UV- absorbing polymer molecule. |
