Abstract
A water-based ink containing an aqueous dispersion of water-insoluble vinyl polymer particles containing a pigment, wherein the water-insoluble vinyl polymer is prepared by copolymerizing a monomer mixture containing (a) a monomer having a salt-forming group, (b) a monomer having a long-chain alkyl group, (c) a macromer, (d) a monomer having a polyoxyalkylene group, and (e) a monomer copolymerizable with the monomer having a salt-forming group (a), the monomer having a long-chain alkyl group (b), the macromer (c) and the monomer having a polyoxyalkylene group (d). The water-based ink can be suitably used, for instance, as a water-based ink for inkjet recording and the like.
