Abstract:
An aqueous ink for ink jet having a high color developing property, capable of recording an image having an excellent hue, and having excellent storage stability, containing a coloring material and a water-soluble organic solvent is provided. The coloring material is a compound represented by the following General Formula (1). The water-soluble organic solvent contains a first water-soluble organic solvent having two or more hydroxy groups and having a Log P value of −1.88 or more to −1.09 or less. The content (mass %) of the first water-soluble organic solvent is 5.0 times or more to 30.0 times or less by a mass ratio with respect the content (mass %) of the coloring material.
