Abstract
Disclosed herein are carbon black surface-modified with benzene compound of Formula 1 described in the specification and a carbon black dispersion composition for a black matrix using the carbon black. The carbon black dispersion composition uses carbon black surface-modified with the benzene compound of Formula 1, or about 0.1 to about 20% by weight of a cardo compound selected from cardo monomers, oligomers, polymers and mixtures thereof. The carbon black dispersion composition can provide improved adhesive properties, uniformity and resolution of black matrix patterns, and no undercut is formed on the black matrix patterns.
