Abstract
A thermal transfer sheet includes a thermal transfer dye layer containing a dye on one surface of a base material sheet and a heat-resistant lubricating layer on the other surface, wherein the heat-resistant lubricating layer contains at least one type of silicone compound represented by Chemical formula 1 or Chemical formula 2 described below. In Chemical formula 1 and Chemical formula 2, R1 contains an alkyl group, an alkylene group, or a phenyl group and may have an ether or ester bond, R2 represents an alkyl group or an alkylene group having the carbon number of 1 to 50, and n and m represent individually an integer of 1 or more, and or less.
Claims3
A thermal transfer sheet comprising:
- a base material sheet comprising a top surface and a bottom surface opposite to the top surface;
- a thermal transfer dye layer containing a dye, the thermal transfer dye layer is disposed on the top surface of the base material sheet and a heat-resistant lubricating layer is disposed on the bottom surface of the base material sheet,
- wherein,
- the heat-resistant lubricating layer contains at least one silicone compound represented by Chemical formula 1 or Chemical formula 2,
- Chemical formulae 1 and 2 being,
- where in each of Chemical formula 1 and Chemical formula 2, each of R1 contains an alkyl group, an alkylene group, a phenyl group, an ether group or an ester group, each of R2 represents an alkyl group or an alkylene group having the carbon number of 1 to 50, and n and m represent individually an integer of 1 to 200.
