Title:
HEAT TRANSFER SHEET
Document Type and Number:
WIPO Patent Application WO/2017/170779
Kind Code:
A1
Abstract:
Provided is a heat transfer sheet with which it is possible to inhibit the occurrence of print wrinkles even when the energy applied to the heat transfer sheet during printing is maintained at a high level. A heat transfer sheet to which a color material layer 3 containing a color material is provided on one surface of a base material 1, wherein energy is applied to the heat transfer sheet 10 at 0.22 mJ/dot on the other surface side of the base material 1, the color material contained in the color material layer 3 is caused to migrate to a transfer body, after which the heat transfer sheet corresponding to the region to which the energy was applied is cut out, and when a tensile test is performed on the cut-out heat transfer sheet at a tensile rate of 3mm/min, the tensile strength is 2.6 N/cm or greater, the tensile strength being obtained by converting the stress (N) at which the cut-out heat transfer sheet reaches a yield point to per 1-cm width of the cut-out heat transfer sheet .
