摘要： A pigment dispersion comprising a colour pigment represented by formula (I) wherein, R1 is selected from the group consisting of hydrogen, a halogen atom, a methyl group, an ethyl group, a methoxy group, an ethoxy group, —CF3, —COOH, —COOCH3 and R2, R4 and R5 are independently selected from the group consisting of hydrogen, a halogen atom, a methyl group, an ethyl group, a methoxy group, an ethoxy group, —CF3, —COOH and —COOCH3; R3 is selected from the group consisting of hydrogen, a halogen atom, a methyl group, an ethyl group, a methoxy group, an ethoxy group, —CF3, —COOH, —COOCH3, —SO2NH—C6H5, —CONH—C6H5, —CONH—C6H5—CONH2 and —CONH2; R6 and R7 are independently selected from the group consisting of hydrogen, a halogen atom, a methyl group, an ethyl group, a methoxy group, an ethoxy group, —CF3, —COOH and —COOCH3, or R6 and R7 represent the necessary atoms to form an imidazolone ring; and a polymeric dispersant having via a linking group covalently linked to its polymeric backbone at least one pending chromophore group which has a molecular weight smaller than 95% of the molecular weight of said colour pigment. The pigment dispersion can be advantageously used in inkjet inks.
