    Abstract: In an ink-jet recording process which comprises forming droplets of an ink and recording on an image receiving material by using the droplets, said ink is prepared by dispersing fine particles of pigment into aqueous dispersion medium containing polymer having both a hydrophilic and a hydrophobic construction portion. An average particle size (D micron) of the pigment and an average molecular weight of the polymer satisfy the relationship represented by the following equation. Dx5x102
