    • A method for preparing a surface modified organic pigment comprising 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, 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 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. Surface modified organic pigments are also disclosed
