Aqueous ink, ink cartridge, and ink jet recording method |
| abstract |
This invention is an inkjet aqueous ink containing a pigment and a water-soluble organic solvent. The pigment contains a self-dispersing pigment in which carboxylic acid groups are directly bonded to the surface of carbon black particles having a DBP oil absorption of 120 mL / 100 g or more and 150 mL / 100 g or less, and a surface charge of 0.20 mmol / g or more and 0.25 mmol / g, The solvent contains a first water-soluble organic solvent having a relative dielectric constant of 28.0 or more at a temperature of 25 ° C., and the content ratio of the first water-soluble organic solvent to the total content of the water-soluble organic solvent is 50.0 mass% or more and 60.0 mass% or less. |
