To provide a modified carbon black excellent in dispersability, light insulation property, and photosensitivity by a simple operation, a photosensitive black resin composition suitable for a black matrix resist for a colored filter capable of forming a black matrix of high dispersion stability, resolution, photosensitivity, and low reflectivity, a black matrix resist using the photosensitive black resin composition, and a black matrix using the black matrix resist.
This modified carbon black excellent in dispersion stability and having a radical-polymerizable group and its dispersion solution are obtained by treating a carbon black with a compound having an ethylenic unsaturated group and an isocyanato group in a molecule, and the above-mentioned purpose is dissolved using the modified carbon black.
