PROBLEM TO BE SOLVED: To provide a thermal transfer sheet formation film which can provide thermal transfer sheets corresponding to the types of L size etc. only by preparing the thermal transfer sheet formation film that becomes one type of a jumbo roll, and in which at least two or more thermal transfer sheets which a printer can identify the marks corresponding to the above types even if a common detection mark is possessed as a jumbo roll are arranged in an integrated manner.SOLUTION: The thermal transfer sheet is formed by continuously repeating dye layer units comprising at least dye layers of three or more colors on the base material sheets, wherein, the dye layer units all have a constant length (A) or a constant length (B) that differs from the constant length (A) in nearly vertical direction to a direction where the dye layer units are repeatedly provided. In the thermal transfer sheet formation film, the thermal transfer sheet is arranged in the nearly vertical direction, the detection marks formed between the dye layer and the dye layer unit that are mutually adjacent, and the detection marks formed between the dye layers are all the first patterns. |
