Abstract
A thermal transfer sheet includes coloring material layers D, D, and D. Transferred images respectively formed by the coloring material layers D, D, and Dhave a value C defined by mathematical formula 1 of less than 12, and colorimetric values P (a*, b*) defined by mathematical formulae 2 and 3 different from one another:=([)  (mathematical formula 1)where C represents chroma and a* and b* each represent a colorimetric value equivalent to L*=38,[*]=()/()*(38−)+  (mathematical formula 2), and[*]=()/()*(38−)+  (mathematical formula 3)where Lx, ax, bx, Ly, ay, and by represent colorimetric values at adjacent step Sx and step Sy near L*=38 when a stairstep image is formed by transfer.
