<P>PROBLEM TO BE SOLVED: To provide an energy ray-curable inkjet ink composition which is excellent in stretchability of a printed film, curability, adhesiveness, and continuous delivering properties. <P>SOLUTION: The energy ray-curable inkjet ink composition comprises at least a colorant; 8-60 mass% of a monofunctional monomer (A) having a glass transition temperature of less than -25°C; 25-40 mass% of a bifunctional oligomer (B) which is polymerized to have an elongation of 130% or more at 25°C; at least one photopolymerization initiator (C) selected from the group consisting of an acylphosphine oxide base initiator (C-1) and a mixed initiator (C-2) of an α-aminoalkylphenone-based initiator and a thioxanthone-based initiator; and a surface tension adjusting agent (D). <P>COPYRIGHT: (C)2010,JPO&INPIT |
