ABSTRACT:
There is provided by the present invention a thermal transfer ribbon which employs reactive binder components that increase in molecular weight when heated during transfer to provide images with high scratch and smear resistance. The reactive components comprise an epoxy resin binder and crosslinker for the epoxy resin binder which are maintained in separate phases within the thermal transfer layer until exposed to a thermal print head through the use of a coating formulation solvent which does not solubilize either the crosslinker or the epoxy resin binder or both.
