摘要:
A sublimation thermal transfer recording material which includes a substrate and an ink layer formed on the substrate for forming a color image, the ink layer including a plurality of sublimable dye groups each of which has different hue and each of which includes one or more sublimable dyes, wherein, provided that weighted average values of solubility of each dye to toluene in each sublimable dye group are values D1, D2, D3, . . . , and Dn, and a maximum value thereof is Dh, each of the values Dn other than the maximum value Dh is greater than about 0.5×Dh, and/or wherein, provided that weighted average values of a product of solubility of each dye to toluene and an extinction coefficient of the dye in each sublimable dye group are values E1, E2, E3, . . . , and En, and a maximum value thereof is Eh, each of the values En other than the maximum value Eh is greater than about 0.5×Eh.
