PROBLEM TO BE SOLVED: To provide a thermal transfer sheet dispensing with detection mark ink transferred as printed matter to be unused, eliminating a unit for printing a detection mark to be enhanced in manufacturing work efficiency and having a detection mark stably detectable by a reading sensor. SOLUTION: In a thermal transfer sheet wherein a dye layer and detection marks 12 are provided on one surface of a base material sheet 1, each of the detection mark 12 is formed from a black dye layer 16 of which the coating amt. after drying is 1.5-3.0g/m<2> Or, in a thermal transfer sheet wherein a dye layer and the detection marks 12 are provided on one surface of the base material sheet 1, each of the detection marks is formed by superposing an yellow dye layer 13, a magenta dye layer 14 and the cyan dye layer 15 one upon another and the coating amt. thereof after drying is 3.0-8.0g/m<2> . |
