INKJET INK, MANUFACTURING METHOD OF INKJET INK AND PRINTING METHOD

摘要

PROBLEM TO BE SOLVED: To provide an inkjet ink having well dispersed pigment particles and usable suitably as a UV-cure inkjet ink for on-demand printing.

SOLUTION: The inkjet ink contains an organic dispersion medium containing a polymerizable compound, a black pigment having an average particle size of ≤200 nm that is formulated in a ratio of ≥2 wt% and ≤30 wt% to the above organic dispersion medium, a pigment dispersion body containing a resin dispersant, and an ionic compound. The zeta potential of the black pigment to the organic dispersion medium or at least one component of the organic dispersion medium is ≥-10 mV and ≤+100 mV.
