Abstract
There is provided by the present invention a thermal transfer medium which employs reactive components that crosslink when heated during image transfer to provide images with high scratch and smear resistance. The reactive components comprise an encapsulated liquid epoxy resin and a crosslinker which remain separate while incorporated within a thermal transfer layer until exposed to a thermal print head.
