Aqueous ink, ink cartridge, and ink jet recording method

An aqueous ink for ink jet comprising:

• a pigment;
• a resin dispersant for dispersing the pigment;
• a fluorinated surfactant;
• a water-soluble organic solvent;
• and
• a water-soluble urethane resin,
• wherein the pigment comprises at least one pigment selected from the group consisting of (a) quinacridone pigments, (b) quinacridone solid solution pigments formed from two or more of the quinacridone pigments, (c) diketopyrrolopyrrole pigments, and (d) C.I. Pigment Violet 23, wherein the quinacridone pigments comprise at least one pigment selected from the group consisting of C.I. Pigment Violet 19, C.I. Pigment Red 122, C.I. Pigment Red 202, and C.I. Pigment Red 209, and wherein the diketopyrrolopyrrole pigments comprise at least one pigment selected from the group consisting of C.I. Pigment Red 254, C.I. Pigment Red 255, and C.I. Pigment Red 272,
• wherein the resin dispersant comprises a water-soluble acrylic resin and has an acid value of 150 mg KOH/g or more to 200 mg KOH/g or less,
• wherein the fluorinated surfactant comprises a perfluoroalkyl ethylene oxide adduct having a perfluoroalkyl group with six or less carbon atoms,
• wherein the water-soluble organic solvent comprises (i) a water-soluble organic solvent A having a dielectric constant of 40.0 or more and (ii) a water-soluble organic solvent B having a dielectric constant of 3.0 or more to 20.0 or less,
• wherein a content p (% by mass) of the pigment is 5.00% by mass or less,
• wherein a content a (% by mass) of the water-soluble organic solvent A relative to the content p (% by mass) of the pigment is 2.0 times or more in terms of mass ratio,
• wherein a content b (% by mass) of the water-soluble organic solvent B relative to the content a (% by mass) of the water-soluble organic solvent A is 0.6 times or less in terms of mass ratio,
• wherein the content b (% by mass) of the water-soluble organic solvent B relative to a content f (% by mass) of the fluorinated surfactant is 10.0 times or more in terms of mass ratio, and
• wherein the water soluble urethane resin has an acid value of 45 mg KOH/g or more to 70 mg KOH/g or less.
