<P>PROBLEM TO BE SOLVED: To provide an inkjet ink composition improved in dispersibility and stability of fine pigment, and an inkjet recording method and a printed material using the ink composition. <P>SOLUTION: The inkjet ink composition includes at least one type of organic pigment exhibiting an orange, violet, or green color, a polymer represented by a formula (1), and an actinic radiation-curable compound. The inkjet recording method and the printed material using the inkjet ink composition are also provided. In the formula (1), R<SP>1</SP>represents an (m+n)-valent organic linking group, R<SP>2</SP>represents a monovalent or divalent organic linking group, A<SP>1</SP>represents a monovalent organic group comprising a pigment adsorbing structure, m represents 1-8, n represents 2-9, m+n is 3-10, and P<SP>1</SP>represents polymer skeleton. <P>COPYRIGHT: (C)2009,JPO&INPIT |
