PURPOSE:To improve such properties as reproducibility in cyan color, coloring density, clearness and various fastnesses by using a mixture, wherein the dye expressed by another formula is mixed into a mixture of the dyes expressed by three kinds of specified formulas, for the dye contained in a dye layer. CONSTITUTION:A heat transfer sheet is constituted by forming a dye layer on one surface of a base material sheet. The dye contained in the dye layer is made to be the mixture, wherein the dye expressed by another formula is further mixed into the mixture of the dyes expressed by the three kinds of formulas shown in the figure. The mixing ratio of the dyes is set in the following relationship. Namely, when the dye of the second formula containing NHCH3 is made to be a part (x), 0<=x<=30 is set; the dye of the third formula containing NH2 is set as dye=(1-0.2x) to (15-0.5x) (0<=x<=5) and 0 to (15-0.5x) (5<=x<=30); and the dye of the first formula containing NHCOCH3 is set as dye = first formula + second formula + third formula = 100. The mixing ratio between the dyes from the first formula to the third formula and the dye of the fourth formula is set at 55:45-95:5. |
