COMPOSITION CONTAINING POLYMER COMPOUND AND IMAGE FORMATION METHOD AND APPARATUS

WIPO Patent Application WO/2006/107112

A1

It is intended to provide an ink composition the dispersibility and fastness of which have been improved by a dispersion composed of a coloring matter encapsulated in a crosslinked hydrophobic block segment in a dispersion polymer and which is excellent in dispersion stability and re-dissolution properties. An ink composition comprising an amphiphilic block polymer compound having a coloring matter encapsulated therein and a vehicle, characterized in that the amphiphilic block polymer compound having the coloring matter encapsulated therein forms a dispersion having its hydrophobic block segment as an internal core and the hydrophobic block segment has been crosslinked.
