    摘要: Disclosed is an ink composition which comprises an aqueous liquid vehicle, a water-soluble dye, and particles of a block copolymer of the formula ABA, wherein A represents a hydrophilic segment and B represents a hydrophobic segment, said ABA particles having an average diameter of about 300 Angstroms or less. The ink is particularly suitable for use in ink jet printing systems, especially thermal ink jet printing systems.
