摘要

An ink jet ink is disclosed which includes water, a water-soluble organic solvent and a coloring material and has excellent properties. The coloring material is a specific phthalocyanine derivative and is contained in a specific amount in the ink. The water-soluble organic solvent includes a specific amount of 2-pyrrolidone. In addition, a d₇₅ value is in a specific range where the d₇₅ value corresponds to 75% of a dispersion distance distribution, measured by a small angle X-ray scattering method, of molecular aggregates in the ink jet ink whose coloring material concentration is adjusted to 0.5 mass %.
