Title:
HEAT TRANSFER SHEET
Document Type and Number:
WIPO Patent Application WO/2017/111097
Kind Code:
A1
Abstract:
Provided is a heat transfer sheet capable of suppressing heat fusion between an object to which the sheet is to be transferred and the heat transfer sheet, even when energy to be applied to the heat transfer sheet is increased when transferring a transfer layer to the object to which the sheet is to be transferred. A heat transfer sheet 100 has a transfer layer 10 located on one surface of a substrate 2. The heat transfer sheet 100 is superimposed on an object 300 to which the sheet is to be transferred, and the transfer layer 10 is continuously transferred to the object 300 to which the sheet is to be transferred under conditions of an applied power of 0.15 W/dot and a heat transfer sheet conveyance speed of 84.6 mm/sec using a printer 200 which has: a heat transfer sheet feeding means 201; a heating means 202; a heat transfer sheet winding means 203; a measurement means 204 located between the heating means 202 and the heat transfer sheet winding means 203 which measures a tensile strength of the heat transfer sheet conveyed along a conveyance path; and a peeling means 205 located between the heating means 202 and the measurement means 204. The tensile strength measured by the measurement means 204 is 0.1 N/cm or lower when the transfer layer 10 transferred to the object 300 to which the sheet is to be transferred is peeled from a component contacting the transfer layer of the heat transfer sheet 100.
