Patent ID: 8288314

Claim:
A heat-sensitive transfer sheet, comprising: a base film; a dye layer containing a heat-transferable dye and a resin formed on one side of the base film; and a heat-resistant lubricating layer containing talc particles as one kind of inorganic particle and a resin formed on the other side of the base film; wherein, when a projected area corresponding to each of the talc particles in the heat-resistant lubricating layer is obtained from an electron beam image that is obtained by irradiating electron beams accelerated at 20 kV from a side of the heat-resistant lubricating layer of the heat-sensitive transfer sheet using a scanning electronic microscope, an average projected area of talc particles each having the projected area of 10 square Î¼m or more is 80 square Î¼m or less, and a variation coefficient that is obtained by dividing a standard deviation of the projected areas of talc particles each having the projected area of 10 square Î¼m or more by the average projected area is 0.80 or less.
