Summary: | The present invention relates to surface modified organic black pigments, surface modified carbon blacks, pigment mixtures and dispersions formed with these pigments, curable compositions, black matrices, and products incorporating them. The surface modified organic black pigment can have attached at least one organic group having the formula -X-Z, wherein X, which is directly attached to the pigment, represents an arylene group, a heteroarylene group, an alkylene group, an aralkylene group, or an alkarylene group, and Z represents at least one ionic group, at least one ionizable group, at least one nonionic group, at least one polymeric group, or any combinations thereof. Also disclosed are carbon black pigment combinations with the surface modified organic black pigments, low dielectric black dispersions, films, and black matrices containing them. Methods of preparing and making these various materials also are provided. |
