摘要： Disclosed are an ink composition which can satisfy, on a high level, various property requirements for ink compositions for use in ink jet recording (e.g., excellent ejection stability and realization of images free from feathering or color-to-color bleeding) and can realize good images by sublimation transfer. A sublimation transfer ink jet recording method using the ink composition is also disclosed. The ink composition comprises a heat transferable dye, a glycol ether, an acetylene glycol surfactant, and water. This ink composition is printed by ink jet recording onto an intermediate transfer medium to form a latent image on the intermediate transfer medium, and the intermediate transfer medium is then put on the surface of a receptor object, followed by heating of the intermediate transfer medium at a sufficient temperature and for a sufficient time to sublimate the heat transferable dye and to deposit the sublimated dye onto the surface of the receptor object. This recording method can realize good transferred images suffering from minimized bleeding.
