ABSTRACT:
The invention provides a block polymer compound enabling satisfactory dispersion of a colorant in a solvent, and an ink composition containing such block polymer compound. The block polymer compound of the invention is a block polymer compound having at least three block segments, comprising block segments A, B and C arranged in succession, wherein the block segment C is most solvent attractive while the block segment A is most solvent repulsive, and at least either one of the block segments includes an ionic group or an acidic group.
