摘要

An ink comprises 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 1/5000, but lower than 1/20. An ink-jet recording process comprises the step of ejecting the ink by an ink-jet system. An ink set comprises 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 comprises 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.
