Abstract
A sublimating dye ink for ink jets of the present invention contains water, a sublimating dye, a humectant and an anionic polymer dispersant. The anionic polymer dispersant is a styrene-(meth)acrylic acid-based copolymer having an acid value of 160 to 250 mgKOH/g and a weight average molecular weight of 8,000 to 20,000. The ink contains further as a penetrant an acetylene glycol-based compound expressed by a chemical formula (I) below. A sublimation transfer dyeing method of the present invention includes: inkjet printing the ink on a sheet recording medium; and superposing a printed surface of the recording medium on an object to be dyed, then heating to sublimate-transfer the sublimating dye to the object to be dyed. Thereby, the present invention provides a sublimating dye ink for ink jets containing a sublimating dye, which has high-quality and stable recording performance, maintains the ink storage stability, and at the same time, the ink has a high print density on a surface of a recording medium, and reduces environmental pollution during a dyeing process.
