Abstract:
Provided is an aqueous ink that enables the recording of images having high optical density and excellent toughness and has excellent reliability. An aqueous ink for ink jet includes a pigment, a resin having an anionic group, a salt and a water-soluble organic solvent. The pigment is a self-dispersible pigment in which an anionic group is bonded to the particle surface of carbon black directly or through another atomic group, the resin has a weight-average molecular weight of 20,000 or less, the water-soluble organic solvent includes glycerol and an additional solvent other than glycerol, and the content (% by mass) of the additional solvent relative to the content (% by mass) of glycerol in terms of mass ratio is 0.6 times or less.

Claim (Index 3):
The aqueous ink according to  claim 1 , wherein the content (% by mass) of the glycerol relative to a content (% by mass) of the self-dispersible pigment in terms of mass ratio is 4.5 times or more to 6.0 times or less.
