PROBLEM TO BE SOLVED: To provide a sublimation type heat transfer medium with a heat-resistant slipping layer preventing deformation when the sublimation type heat transfer medium in a heat transfer printer is carried, suppressing stripe-shaped unevenness of printing density and reducing contamination and wear of a thermal head.SOLUTION: In the sublimation type heat transfer medium, the heat-resistant slipping layer 2 is provided on one face of a base material 1, and at least dye layers 5, 6, 7 including sublimation dye and resin and sensor marks 4 are provided on the other face of the base material 1. In an environment of 23°C and 30%RH, saturation zone voltage when ±10 kV of an electric field is applied from 20 mm of a distance from the face of the heat-resistant slipping layer 2 is 1 kV or more. The heat-resistant slipping layer 2 includes two types or more of phosphate ester, magnesium oxide and particles. At least one type of the phosphate ester is a compound having 30°C or more of a melting point, and the total weight of the phosphate ester, magnesium oxide and particles is less than 10% of the overall weight of the heat-resistant slipping layer 2. |
