Abstract:
An ink composition includes a first component which is a hydrophilic solvent, a second component which is a hydrophobic solvent, a third component which is an amphiphilic solvent, and a fourth component which includes a solute or a dispersing element, and when the third component evaporates, the ink composition is separated into a phase which mainly includes the first component and a phase which mainly includes the second component.
