Abstract
A thermal transfer sheet of the present invention comprises a substrate, a peeling layer and a colorant layer, the peeling layer and the colorant layer being disposed on one side of the substrate in this order when viewing from the substrate, wherein an applied amount of the peeling layer is in a range of 1.5 to 5.0 g/m , an applied amount of the colorant layer is not more than half the applied amount of the peeling layer, the peeling layer has a melt viscosity in a range of 10 to 300 cP at 100° C., and the colorant layer contains at least one thermoplastic resin selected from the group consisting of ethylene-acrylic acid copolymers(EAA), ionomer, styrene-butadiene rubbers(SBR), and nitrile-butadiene rubbers(NBR) at a proportion in a range of 10 to 60% by weight. The thermal transfer sheet can print an image having a quality appearance with no void and nick and an excellent wear resistance on a receiving sheet having a low smoothness, in particular a rough paper.
