ABSTRACT:
There is provided by the present invention methods for preparing coating formulations and thermal transfer ribbons which provide images of high resolution by thermal transfer printing. The formulations contain an incompatible resin or wax component for reduced cohesiveness between the components of the thermal transfer layer. These methods employ thermoplastic resins and waxes with distinct solubility in the absence of solvent to reduce cohesion but are sufficiently compatible as to exhibit film forming properties. A method for modifying a coating formulation is also provided where an incompatible resin or wax components is added thereto.
