Abstract: MODIFIED RESISTIVE LAYER IN THERMAL TRANSFER MEDIUM A thermal ribbon having a minute coating of graphite powder on the outer side of the resistive layer. The improved electrical interface with print electrodes reduces ribbon and printhead damage. The graphite also reduces friction and loosens material which builds-up at the printhead.

Abstract: INTERMEDIATE LAYER IN THERMAL TRANSFER MEDIUM In accordance with this invention a transfer medium for thermal printing is disclosed which has a very thin layer of silicon dioxide as a lamination on the resistive layer. A heat-flowable layer of marking material can be used on the side opposite the resistive layer. A typical embodiment has a resistive layer comprising a particulate, conductive filler material and a polymeric binder; a layer of silicon dioxide; a metal layer contacting the silicon dioxide opposite the resistive layer; and a solid, meltable ink on the other side of the metal layer.
