Sublimation thermal transfer sheet and combination of sublimation thermal transfer sheet and transfer receiving article

A sublimation thermal transfer sheet comprising:

• a substrate, and
• yellow, magenta, and cyan colorant layers provided on one surface of the substrate,
• wherein the yellow colorant layer comprises at least a binder resin Y and a sublimable dye Y having a molar absorption coefficient of not less than 50000 and a molecular weight of not more than 650,
• wherein the magenta colorant layer comprises at least a binder resin M and a sublimable dye M having a molar absorption coefficient of not less than 50000 and a molecular weight of not more than 650,
• wherein the cyan colorant layer comprises at least a binder resin C and a sublimable dye C having a molar absorption coefficient of not less than 50000 and a molecular weight of not more than 650, and
• wherein an average of a mass ratio between the binder resin Y and the sublimable dye Y (sublimable dye Y/binder resin Y), a mass ratio between the binder resin M and the sublimable dye M (sublimable dye M/binder resin M), and a mass ratio between the binder resin C and the sublimable dye C (sublimable dye C/binder resin C) is not less than 0.7.
