Beschreibung
Zusammenfassung:	An aqueous ink comprising water, a water-soluble organic solvent and at least two pigments. The aqueous ink is used together with a reaction liquid containing a reactive component that reacts with the aqueous ink to cause aggregation or gelation of the aqueous ink. The at least two pigments have a difference in precipitation value to the reaction liquid of 0.2 or less.
