ABSTRACT:
A thermal transfer material suitable for two-color recording comprises a support and at least a first adhesive layer, a first ink layer, and a second ink layer disposed in this order on the support. The adhesion strength F.sub.1 between the support and the first ink layer and the adhesive strength F.sub.2 between the first and second ink layers satisfy the relations of F.sub.1 >F.sub.2 at a higher temperature and F.sub.1 <F.sub.2 at a lower temperature. The first ink layer comprises a binder having a glass transition temperature (Tg) of 0.degree. C. or below and 25-85 wt. % of a pigment. 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 composition of the first ink layer.
