Provided are a sublimation thermal transfer sheet and a combination of a sublimation thermal transfer sheet and a transfer receiving article that meet the demand for increase in the density of a color image to be formed, that prevent decrease in the adhesiveness of a protective layer optionally formed on the color image.

In a sublimation thermal transfer sheet including a substrate and yellow, magenta, and cyan colorant layers provided on one surface of the substrate, the yellow, magenta, and cyan colorant layers each contain at least a binder resin and a sublimable dye having a molar absorption coefficient of not less than 50000 and a molecular weight of not more than 650, and the average of the mass ratios of the respective binder resins and sublimable dyes (sublimable dye/binder resin) in the yellow, magenta, and cyan colorant layers is not less than 0.7.
