Provided are a carbon black dispersion composition for a black matrix, a black matrix for a color filter using the composition which is excellent in adhesion, uniformity and resolution, and a color filter containing the black matrix. The carbon black dispersion composition is prepared by wetting a mixture comprising 5-40 wt% of carbon black, 1-10 wt% of a dispersant, 0.1-20 wt% of a cardo-based compound and 30-90 wt% of a solvent; dispersing the obtained one by using a continuous cyclic bead mill; and leaving it alone at a room temperature for maturing. Preferably the dispersing process is carried out by using a zirconium oxide bead having a diameter of 0.2-1.5 mm. |
