ABSTRACT:
A heat-sensitive transfer medium comprises a support and at least two heat-transferable ink layers including a first and a second ink layer. The first ink layer has relative adhesions with the second ink layer and the support which are reverse at a higher temperature from those at a lower temperature. When the heat-sensitive transfer medium is superposed with paper, a heat energy is applied, and the transfer medium is separated from the paper; the second ink layer is selectively transferred or both the first and second ink layers are transferred to the paper depending on the length of time from the heat application until the separation of the transfer medium, whereby two color images can be formed by a single transfer medium.
