<P>PROBLEM TO BE SOLVED: To provide an inkjet ink composition, an ink set, an inkjet recording method, and a printed matter, high in glossiness, having a high image density, reduced in grain-like feeling, and excellent in base material tight contactness and blocking resistance. <P>SOLUTION: The inkjet ink composition, the ink set, the inkjet recording method, and the printed matter contain (component A-1) N-vinyllactams, (component A-2) a compound of Formula (1), (component A-3) a compound of Formula (2) or formula (3), and (component A-4) a bifunctional or more (meth)acrylate compound, (component B) a bisacyl phosphine compound as a polymerization initiator, the total content of the (component A-1)-the (component A-3) being 65-90 wt.%, while a content of the (component A-4) being 1-9 wt.%, and a surface tension being 34.0-40.0 mN/m at 25°C. In the Formula (1), R<SP POS="POST">1</SP>represents a hydrogen atom or a methyl group, and X represents a single bond or divalent connecting group. In the Formula (2), R<SP POS="POST">1</SP>represents a hydrogen atom or a methyl group, and X represents a single bond or divalent connecting group. In the Formula (3), R<SP POS="POST">1</SP>represents a hydrogen atom or a methyl group, R2 represents an alkyl group, and n represents an integer of 1-3. <P>COPYRIGHT: (C)2012,JPO&INPIT |
