ABSTRACT:
A process for producing an aqueous ink for inkjet printing capable of giving an elevated print density of printed matters, being improved in fixability to the material to be printed, water resistance and improved storage stability and scarcely scorching onto a printer head. This process comprises dissolving a salt-forming group-having polymer and a hydrophobic dye in a water-insoluble organic solvent to obtain a solution, adding water and a neutralizing agent optionally together with a surfactant to the solution to ionize the salt-forming group of the polymer, emulsifying the resulting mixture, and removing out the solvent from the emulsion to obtain an ink containing an aqueous dispersion of the polymer particles in which the dye has been encompassed.
