ABSTRACT:
A thermal transfer medium which forms images with high speed thermal transfer printers is provided which comprises a substrate, a first coating comprised of at least 75 wt. % of a wax, a second coating comprising a sensible material such as a pigment and a binder resin with high hot tack properties in an amount of at least 20 wt. % based on total dry components and an optional third coating which does not contain any coloring agent. The first coating has a melt viscosity and cohesion lower than that of the second coating and preferably lower hot tack properties to simplify complete transfer to a receiving substrate. The coating formulation provides high adhesion to a receiving substrate with reduced adhesion to the flexible substrate of the thermal transfer medium, allowing for rapid transfer to a receiving substrate as required with high speed thermal transfer printers.
