Thermal transfer material
Abstract
Abstract A thermal transfer material suitable for two-color recording comprises a support and at least a first ink layer and a second ink layer disposed in this order on the support. The adhesion strength F 1 between the support and the first ink layer and the adhesive strength F 2 between the first and second ink layers satisfy the relations of F 1 >F 2 at a higher temperature and F 1 <F 2 at a lower temperature. The total ink layers on the support having a tensile strength of 8-20 kg/cm 2 . Two color recording is effected by superposing the thermal transfer material on plain paper, applying a pattern of heat and separating the thermal transfer material from the paper while changing the time from heating until the separation, i.e., temperatures at the time of separation. Sharp edge cutting of the heated portion is ensured by the definition of the tensile strength.
