The present invention provides a pigment-dispersed recording liquid that has excellent gloss, good print quality, and excellent print resistance, and also has good ejection properties. An aqueous pigment dispersion comprising (a) an aqueous medium, (b) a pigment, and (c) a dispersant. (C) The dispersant is obtained by copolymerizing a hydrophobic monomer, an anionic monomer, and an oxyalkylene chain monomer represented by the following formula (1). The polymer (I) has a ratio of 0.1 to 1.0 and an anionic monomer unit content of 10% by weight or less. (R 1 is a (meth) acryloyloxy group, etc. R 2 is an alkyl group having 1 to 20 carbon atoms, h, j are 1 to 5, i is 1 to 100, and k is 0 to 50.) [Selection figure] None |
