摘要： A light-curable inkjet printing ink composition characterized by good curability under ultraviolet light, particularly ultraviolet light from a light-emitting diode (LED) light source, good adhesion to a polyvinyl chloride sheet, etc., and good flexibility of the coating film of ink. As a means for achieving the object, a light-curable inkjet printing ink composition is provided that contains a light-polymerizable component and a light-polymerization initiator, where the light-curable inkjet printing ink composition contains 70 to 100 percent by mass of monofunctional monomers relative to the total mass of the light-polymerizable component; wherein the monofunctional monomers comprise: (A) a monofunctional monomer whose homopolymer has a glass transition temperature of 20°C or above; and (B) a monofunctional monomer whose homopolymer has a glass transition temperature of below 20°C; and (A) is contained by 30 to 90 percent by mass, while (B) is contained by 10 to 70 percent by mass, relative to the total mass of the light-polymerizable component.

摘要： An object is to provide a non-aqueous inkjet ink composition offering excellent wettability, fixing property, solid-fill property, anti-mottling property, as well as discharge stability, even when printed at high speed on a matter to be printed whose printing side is constituted by a polyvinyl chloride or ethylene-vinyl acetate copolymer or other vinyl polymer, etc. As means for achieving the object, a non-aqueous inkjet ink composition containing an acrylic resin, a pigment, a pigment dispersant, and an organic solvent, is provided, wherein such non-aqueous inkjet ink composition is characterized by containing, as the organic solvent, a propylene carbonate and a diethylene glycol dialkyl ether, wherein the propylene carbonate is compounded by 5 to 25 percent by mass in the ink composition, while the diethylene glycol dialkyl ether is compounded in a manner providing a ratio of diethylene glycol dialkyl ether/propylene carbonate falls in a range of 3 to 8.
