    摘要： A method of preparing a pigment includes, in order, the steps of: a) providing a pigment containing a nucleophile group under basic conditions; b) reacting the pigment with a compound according to Formula (I): wherein, X is a halogen atom or a tosylate group, and R1 and R2 independently represent an alkyl group; and c) hydrolyzing the R1-O bond and/or the R2-O bond. The obtained pigments can be used in non-aqueous pigment dispersions.
