<p>PURPOSE: A pigment dispersion composition is provided to have dispersity and disperse stability with maintaining optical properties like brightness, contrast ratio, etc, and to manufacture a superior color filter. CONSTITUTION: A pigment dispersion composition comprises at least one kind of pigment derivative selected from a compound in chemical formula 1. In chemical formula 1, Q is organic pigment residue, m is the integer of 0-4, R1 is selected from hydrogen, a substituted or non-substituted C1-20 (hetero)alkyl group, and a substituted or a non-substituted C3-30 (hetero)aryl group. R2 and Ar is selected from hydrogen, halogen, an amine group, a cyano group, a nitro group, a substituted or non-substituted C1-60 (hetero) alkyl group, a substituted or non-substituted C3-60 (hetero) aryl group, a substituted or the non-substituted C1-60 (hetero) alkoxy group, a substituted or non-substituted C3-60 (hetero) aryloxy group, a substituted or the non-substituted C1-60 (hetero) alkylamine group, and a substituted or non-substituted C3-60 (hetero) arylamine group.</p> |
