TLDR
Disclosed is a thermal transfer medium which comprises a mixture of a thermosetting polyimide, a thermoplastic polyimides, and graphite as discussed by the authors, and it has a steel support layer and an intermediate layer of silicon dioxide.Abstract:
Disclosed is a thermal transfer medium which comprises a mixture of a thermosetting polyimide, a thermoplastic polyimide, and graphite. It has a steel support layer and an intermediate layer of silicon dioxide. An outer layer on the steel is the thermal ink. The mixture is applied as a dispersion with a precursor of the thermosetting polyimide. The ribbon may be recoated at the typing station by applying a hot-melt of the ink.read more
