<p><P>PROBLEM TO BE SOLVED: To provide a block polymer compound which improves the dispersibility of color materials and solid materials, and to provide an ink composition using the same. <P>SOLUTION: The block polymer compound has repeating unit structures represented by the general formula (1) [X is a polyalkenyl repeating unit; A is a 1 to 15C linear or branched alkylene which may be substituted; (m) is an integer of 0 to 30; when (m) is≥2, A groups may be different from each other, B is a single bond or an alkylene which may be substituted; D is a polycyclic aromatic condensed ring structure which may be substituted; (n) is an integer of 1 to 10; when (n) is≥2, D groups may be different from each other]. The ink composition comprises the block polymer compound, a solvent, and a coloring material. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
