<P>PROBLEM TO BE SOLVED: To provide an energy ray-curable inkjet ink composition which exhibits a low viscosity without a diluent solvent or heating, has good preservation stability and a good pigment-dispersing property when a coloring material is a pigment, exhibits excellent continuous jetting stability onto a recording medium, satisfies curability at the time of printing, gives good printing qualities on a non-absorbing recording medium and is particularly excellent in adhesion to a recording medium base material. <P>SOLUTION: The energy ray-curable inkjet ink composition comprises the coloring material, a monofunctional monomer, a multifunctional monomer of at least two functionalities and a photopolymerization initiator, where the contents of the monofunctional monomer, the polyfunctional monomer and the photopolymerization initiator in the whole ink composition are 30-90 wt%, 10-50 wt% and 6-20 wt%, respectively, and the viscosity of the whole ink composition is 3-35 mPa s at 25°C. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
