Abstract:
A self-dispersible colorant has a hydrophilic group incorporated into a colorant. A method of preparing the self-dispersible colorant reacts a cyclic anhydride with a reactive colorant in the presence of a Lewis acid. An ink composition comprising the self-dispersible colorant provides long-term storage stability and dispersion stability.
