Abstract
An interactive dye thermal transfer printing apparatus and process uses a dye donor layer and a dye receiver layer, passing the dye donor layer and the opposed receiver layer between a thermal print head and a platen heated to raise the temperature of the dye receiver layer to its glass transition temperature. The thermal print head is image-wise energized to diffuse dye from the dye donor layer to the dye receiver layer. At the same time, thermal energy is transferred from the platen to the dye receiver layer to provide energy to react the dye with the receiver layer.
