PURPOSE:To reduce unpleasant noise at the time of printing by providing a release layer based on wax on a support and providing an ink layer thereon and specifying the ratio of the wax and resin in the release layer and adding a specific amount of an acrylonitrile/butadiene copolymer to the resin component. CONSTITUTION:A thermal transfer recording medium 1 is formed by providing a release layer 3 based on wax on a support 2 and providing an ink layer 4 thereon and further providing a heat-resistant protective layer 5 to the surface on the side coming into contact with a thermal head of the support 2. The ratio of the wax and resin in the release layer 3 is 95 : 5-80 : 20 and an acrylonitrile/butadiene copolymer is added to the resin component in an amount of 5-50 wt.%. When the compounding amount of the acrylonitrile/butadiene copolymer is below 5 wt.%, unpleasant noise is increased and, when said compounding amount exceeds 50 wt.%, the effect of the acrylonitrile/butadiene copolymer itself becomes too large and unpleasant noise is increased and transfer inferiority becomes easy to generate. When the ratio of the resin in the release layer 3 exceeds 20 wt.%, the bonding strength between the release layer 3 and the support 2 becomes high and transfer inferiority is generated. When said ratio is below 5 wt.%, the bonding strength becomes low and the peel of the ink layer 4 is generated. |
