ABSTRACT:
An aqueous inkjet printing ink with excellent water resistance, wherein scorching onto a printer head scarcely occurs, the amount of a hydrophobic dye contained in an aqueous dispersion of a vinyl polymer can be increased, and sharp printed letters having deep color can be provided. The aqueous ink product for inkjet printing comprises a dispersion of a vinyl polymer obtained by copolymerizing one or more selected from a silicone macromer, an acrylamide monomer and a methacrylamide monomer (not having a salt-forming group), or a styrene macromer of a styrene homopolymer or a styrene copolymer having a polymerizable functional group at one terminal end, a polymerizable unsaturated monomer having the salt-forming group, and a monomer capable of polymerizing with these monomers in the presence of a radical polymerization initiator, a hydrophobic dye being contained in the dispersion.
