Document Type and Number:
WIPO Patent Application WO/2019/111851
Kind Code:
A1
Abstract:
Provided are a thermal transfer sheet which enables an improvement in operational efficiency in the manufacture thereof and enables the type thereof to be identified, and a thermal transfer printing device employing the thermal transfer sheet. A thermal transfer sheet 5 comprises a base material 50, and a yellow dye layer 51, a magenta dye layer 52 and a cyan dye layer 53 which are provided on the base material 50. A gap between the yellow dye layer 51 and the magenta dye layer 52 is different from a gap between the magenta dye layer 52 and the cyan dye layer 53. Alternatively, the yellow dye layer 51 and the magenta dye layer 52 overlap partially, and the magenta dye layer 52 and the cyan dye layer 53 overlap partially. The thermal transfer printing device identifies the type of the thermal transfer sheet 5 from the gaps between the dye layers or the widths of the overlaps.
