Abstract
Ink comprising an aqueous medium, a water-insoluble colorant and a dispersant for dispersing the colorant in the aqueous medium, the dispersant being a water-soluble polymer obtained by polymerizing a monomer containing at least one monomer selected from acryloylmorpholine represented by the formula (1): ##STR1## and styrene sulfonate represented by the formula (2): ##STR2## [wherein M is an alkaline metal atom or an amino group] is provided. This ink is suitable for using for an ink-jet recording system because it provides a fast recorded image and is also superior in storage stability and jetting stability.
