Abstract
Abstract A pigment composition is disclosed which includes a pigment and a coloring compound of the general formula (I), <IMAGE> (I) wherein Q represents a residue of a coloring compound other than phthalocyanine, X represents -SO2- or -CO-, m and n represent, respectively, an integer of from 1 to 4 and an integer of from 1 to 6, R represents a hydrogen atom, an alkyl group having from 1 to 20 carbon atoms or an alkenyl group having from 2 to 20 carbon atoms, and R1 and R2 represent, independently, a hydrogen atom, a substituted or unsubstituted alkyl group having from 1 to 20 carbon atoms or a substituted or unsubstituted alkenyl group having from 2 to 20 carbon atoms, or R1 and R2 together form a heterocyclic ring which contains a nitrogen, oxygen or sulfur atom therein.
