METHOD FOR MANUFACTURING WATER-BASED INK FOR INKJET RECORDING

摘要

A method for manufacturing a water-based ink for inkjet recording, said method comprising a step for introducing a solid zirconium compound into a water-based ink by dispersing a pigment in a polymer in a dispersion apparatus using dispersion media particles containing a zirconium compound. The water-based ink includes pigment-containing polymer particles and the solid zirconium compound, and the zirconium compound content of the water-based ink is between 2ppm and 200ppm, inclusive, in terms of the zirconium concentration.
