Abstract: An aqueous dispersion of polymer particles of a water-insoluble vinyl polymer containing a hydrophobic dye, wherein the water-insoluble vinyl polymer is obtainable by polymerizing a monomer composition comprising an alicyclic (meth)acrylate, a salt-forming group-containing monomer, and a monomer copolymerizable with the alicyclic (meth)acrylate and the salt-forming group-containing monomer; and an ink comprising the aqueous dispersion. The aqueous dispersion is excellent in, for instance, storage stability, and the ink is excellent in, for instance, printing reliability, solvent resistance, water resistance and character quality.

Abstract: PROBLEM TO BE SOLVED: To provide an aqueous dispersion for ink-jet printing, satisfying discharge stability and print density and giving excellent gloss when printing on a paper for exclusive use, and to provide a water-based ink.
SOLUTION: The aqueous dispersion for ink-jet printing is an aqueous dispersion of water-insoluble vinyl polymer particles containing colorants, wherein the water-insoluble vinyl polymer is a polymer having a constituent unit represented by formula (1), a constituent unit derived from a salt forming group-containing monomer (a) and a constituent unit derived from a styrene-based macromer (b) and/or a hydrophobic monomer (c) and the terminal of the main chain of the water-insoluble vinyl polymer has two or more hydroxy and/or one or more carboxy, and the water-based ink includes the dispersion. (Wherein, R
1 is H or methyl; and R
2 is a (substituted) 7-22C arylalkyl or a 6-22C aryl).
