ACTIVE ENERGY RAY-CURABLE INKJET INK COMPOSITION

摘要

PROBLEM TO BE SOLVED: To provide an active energy ray-curable inkjet ink excellent in injection characteristics when printed at higher frequency and higher injection speed compared with conventional ones, and especially an active energy ray-curable inkjet ink of 1-pass curable-type.

SOLUTION: The active energy ray-curable inkjet ink contains a dispersion obtained by dispersing a pigment using a resin-type dispersant containing a polyethyleneimine as the main backbone and a urethane skeleton in a side chain, in a reactive monomer containing an ethylenic double bond, and has a viscosity at 25°C of 5-14 mPa.sec.
