HEAT-SENSITIVE TRANSFER DYE, HEAT-SENSITIVE TRANSFER INK USING THE SAME, AND HEAT-SENSITIVE TRANSFER SHEET

Japanese Patent JP3873615

B2

PROBLEM TO BE SOLVED: To provide a heat-sensitive transfer dye suitable for use in a heat- sensitive transfer by sufficiently satisfying various conditions in a sublimation transfer method as a heat-sensitive transfer method, or particularly exhibiting an excellent cyan color as well as a heat-sensitive transfer ink using the same and a heat-sensitive transfer sheet.
SOLUTION: The heat-sensitive transfer dye comprises a phenoxazine compound represented by formula (I), wherein R1 and R2 are each independently and alkyl group which may have a substituent, an alkenyl group which may have a substituent, a cycloalkyl group which may have a substituent, an aryl group which may have a subsistuent of a hydrogen atom. The heat-sensitive transfer ink comprises the heat-sensitive transfer dye, a bonding material and an organic solvent. The heat-sensitive transfer sheet comprises the heat-sensitive transfer dye, and a coloring material layer containing the binding material on a support.
