INK, INK CARTRIDGE, AND INK JET RECORDING METHOD |
摘要 |
Provided are an ink with which an image excellent in both black density and glossiness can be recorded, and an ink cartridge and an ink jet recording method each using the ink. The ink includes: a carbon black; a resin for dispersing the carbon black; a resin fine particle; and a water-soluble organic solvent, in which: the resin fine particle contains at least a unit derived from an ethylenically unsaturated hydrophobic monomer, and a unit derived from a monomer selected from an ethylenically unsaturated acid monomer and a salt thereof, and a ratio of a unit derived from a saturated alkyl group-containing monomer to the unit derived from the ethylenically unsaturated hydrophobic monomer is 95.0 mass % or more; and the water-soluble organic solvent contains a water-soluble organic solvent having a dielectric constant at 20° C. of 18.0 or more and less than 30.0. |
