<P>PROBLEM TO BE SOLVED: To provide an ink with which a monochromatic image excellent in both black density and glossiness can be recorded, and to provide an ink cartridge and an inkjet recording method each using the ink. <P>SOLUTION: The ink includes: a carbon black; a resin for dispersing the carbon black; a resin fine particle; and a water-soluble organic solvent. In the ink, 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. <P>COPYRIGHT: (C)2012,JPO&INPIT |
