(57) Abstract: [PROBLEMS] To provide a water-based ink for inkjet recording, which has a large amount of a hydrophobic dye encapsulated in an aqueous dispersion of a vinyl polymer, has a deep color, is vivid, and has further improved water resistance. SOLUTION: A styrene macromer composed of a styrene homopolymer or copolymer having a polymerizable functional group at one end, a polymerizable unsaturated monomer having a salt-forming group, and a monomer copolymerizable with these monomers. A water-based ink for inkjet recording, which is a dispersion of a vinyl polymer obtained by copolymerizing a monomer and a monomer in the presence of a radical polymerization initiator, the dispersion including a hydrophobic dye encapsulated in the dispersion. . |
