Abstract:
1. An aqueous dispersion for inkjet recording, comprising polymer particles of a water-insoluble vinyl polymer containing a hydrophobic dye, wherein said water-insoluble vinyl polymer is prepared by polymerizing a monomer composition comprising an alicyclic (meth)acrylate (a) which is isobornyl (meth)acrylate, a salt-forming group-containing monomer (b), and a monomer (c) copolymerizable with the alicyclic (meth)acrylate (a) and the salt-forming group-containing monomer (b) wherein the content of the alicyclic (meth)acrylate (a) in the monomer composition is 25 to 75% by weight wherein said aqueous dispersion is prepared by dissolving said water-insoluble vinyl polymer and said hydrophobic dye in an organic solvent, ionizing said salt-forming group of the water-insoluble vinyl polymer, adding water to a resulting solution, dispersing said water-insoluble vinyl polymer in said solution, and thereafter distilling said organic solvent off.
