The present invention relates to a black matrix formed by applying a curable coating composition onto a substrate to form a curable coating, curing the curable coating imagewise to form a coating, and developing and drying the coating. The curable coating composition comprises a vehicle, a curable resin, and at least one modified pigment comprising a pigment having attached at least one organic group having the formula —X—I or —X—NI, wherein X, which is directly attached to the pigment, represents an arylene or heteroarylene group, an alkylene group, an aralkylene group, or an alkarylene group, I represents a non-polymeric group comprising at least one ionic group or at least one ionizable group, and NI represents a non-polymeric group comprising at least one nonionic group. The curable coating composition, curable coating, and cured coating are also described. Also disclosed is a method of controlling the resistivity of a coating.
