Abstract
A heat transfer sheet which has a high recording sensitivity and can form image of high maximum reflection density and of high contrast is provided by containing in an ink layer of the heat transfer sheet at least one dye which has a product of an extinction coefficient (l.cm.sup.-1.g.sup.-1) and an evaporation or sublimation rate at 240.degree. C. (wt %.min..sup.-1) of at least 1.8.times.10.sup.2 (l.wt %.cm.sup.-1.g.sup.-1.min.sup.-1).
