Abstract: A method for preparing a surface modified organic pigment includes the steps of a) reacting the organic pigment in an aromatic hydrocarbon solvent with a surface modifying reagent to form a surface modified organic pigment; and b) washing and drying the surface modified organic pigment; wherein the surface modifying reagent is represented by Formula (I): wherein, X is selected from the group consisting of O, S and N—R3; Y is selected from the group consisting of —O—, and NR4; R1 to R4 are each independently selected from the group consisting of hydrogen, an alkyl group, an alkenyl group, an alkynyl group, a -aralkyl group, an alkaryl group, and an aryl group and s heteroaryl group; with the proviso that when Y—R1 is different from OH that at least one of R2 to R4 is substituted by at least one functional group having a pKa between 2.5 and 9.
