INKJET BLACK INK COMPOSITION FOR SUBLIMATION TRANSFER AND METHOD OF PRODUCING DYED PRODUCT

摘要

PROBLEM TO BE SOLVED: To provide an inkjet black ink composition for sublimation transfer excellent in ejection stability and recoverability from clogging, and to provide a method of producing a dyed product using the inkjet black ink composition for sublimation transfer.SOLUTION: The inkjet black ink composition for sublimation transfer contains a dye A and a dye B. The dye A is a disperse dye having a molecular weight equal to 380 or less and an intramolecular anthraquinone skeleton having a water-soluble group. The dye B is disperse dye having a molecular weight equal to 380 or less. In the inkjet black ink composition for the sublimation transfer, dye solubility of the dye A is greater than dye solubility of dye B, and the dye solubility of the dye B is equal to 10or less.
