<P>PROBLEM TO BE SOLVED: To provide a pigment dispersion composition having a high pigment dispersion ability and a dispersion stability after the dispersion, a coloration curable composition having a good coating property and being capable of forming a uniform coating, a color filter which is of high contrast and the unevenness of color is controlled, and its preparation method. <P>SOLUTION: A pigment dispersion composition comprising (A) an organic pigment, (B) a pigment derivative represented by the general formula (I), and a high molecular compound having a pigment absorbing functional group; and (C) a colored curable composition further comprising (D) a polymeric compound and (E) a polymeric initiator. In the general formula (I), Q represents an organic pigment residual group; A represents an ethylene group and the like; and R represents a hydroxyl group or a group represented by -NH-A-Z. Z represents -SO<SB>3</SB>H, -COOH, or a salt thereof. When, here, R represents the group represented by -NH-A-Z, two -NH-A-Z groups being bound to the same triazine ring may be the same or different from each other. n represents an integer from 1 to 4. <P>COPYRIGHT: (C)2009,JPO&INPIT |
