An ink comprise a dye, a silicon-containing surfactant, an ethylene oxide adduct of acetylene glycol and a liquid medium, wherein a weight ratio of the silicon-containing surfactant to the ethylene oxide adduct of acetylene glycol is not lower than {fraction (1/5000)}, but lower than {fraction (1/20)}. An ink-jet recording process include the step of ejecting the ink by an ink-jet system. An ink set include in combination a first dye having a certain color tone, and a second dye ink having a color tone different from that of the first dye ink, wherein at least one of the first and second dye inks is the above ink. An ink set include dye inks of yellow, magenta and cyan, wherein the dye inks include an ethylene oxide adduct of acetylene glycol respectively, and the dye inks of magenta and cyan further have a silicon-containing surfactant.

An ink set, comprising dye inks of yellow, magenta and cyan, wherein the dye inks comprise an ethylene oxide adduct of acetylene glycol respectively, and the dye inks of magenta and cyan further comprise a silicon-containing surfactant.
A method of improving stability to start-up ejection of an ink for ink-jet printing comprising a step of ejecting the ink, wherein the ink comprises an ethylene oxide adduct of acetylene glycol, a dye and a silicon-containing surfactant.
An ink for ink-jet printing, comprising an ethylene oxide adduct of acetylene glycol, a dye and a silicon-containing surfactant, wherein the ink exhibits excellent stability to start-up ejection even under conditions such that the ink containing no silicon-containing surfactant becomes unstable in start-up ejection.
