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 1):
An aqueous ink for ink jet, the aqueous ink comprising:\n a pigment; a resin having an anionic group; a salt; and a water-soluble organic solvent, wherein the pigment is a self-dispersible pigment in which an anionic group is bonded to a 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 salt is a salt formed by bonding at least one cation selected from the group consisting of an alkali metal ion, an ammonium ion and an organic ammonium ion with at least one anion selected from the group consisting of Cl \u2212 , Br \u2212 , I \u2212 , ClO \u2212 , ClO 2 \u2212 , ClO 3 \u2212 , ClO 4 \u2212 , NO 2 \u2212 , NO 3 \u2212 , SO 4 2\u2212 , CO 3 2\u2212 , HCO 3 \u2212 , HCOO \u2212 , (COO \u2212 ) 2 , COOH(COO \u2212 ), CH 3 COO \u2212 , C 2 H 4 (COO \u2212 ) 2 , C 6 H 5 COO \u2212 , C 6 H 4 (COO \u2212 ) 2 , PO 4 3\u2212 , HPO 4 2\u2212  and H 2 PO 4 \u2212 , the water-soluble organic solvent includes glycerol and an additional solvent other than the glycerol, and a content (% by mass) of the additional solvent relative to a content (% by mass) of the glycerol in terms of mass ratio is 0.6 times or less.
