摘要： A process for producing an ink composition is disclosed which can provide an ink composition that is less likely to create feathering or bleeding and can provide an increased dot diameter in a reduced amount of the ink ejected. According to the process, a pigment, a dispersant, water, and an alkyl ether derivative, with 3 or more carbon atoms, of a polyhydric alcohol and/or an acetylene glycol compound represented by the following formula (I): wherein R1, R2, R3 and R4 each independently represent an alkyl group having 1 to 6 carbon atoms; and n and m are an integer, provided that the sum of n and m is 0 to 30, are dispersed in one another by means of a dispergator to prepare a dispersion which is then used to prepare an ink. The ink composition thus prepared is less likely to cause feathering or bleeding and can realize a large dot diameter in a reduced amount of the ink ejected, as compared with an ink composition prepared by first preparing a dispersion from a pigment and a dispersant and then adding an alkyl ether derivative, with 3 or more carbon atoms, of a polyhydric alcohol and/or an acetylene glycol compound represented by the following formula (I) to the dispersion.
