Resistive ribbon print is obtained by passing current through a resistive layer, thereby creating sufficient heat to melt and transfer a thermally sensitive ink layer. Due to the melting of the layer, complete transfer is achieved which causes the ribbon to be limited to a single use configuration. We have found that by mixing a sublimable dye in a suitable binder such as cellulose nitrate, a ribbon can be fabricated which has multi-use capabilities. The ribbon and the method by which print was obtained are detailed below. The formulation consists of: 10.5 grams Sublimable Print Black 1.5 grams Nitrocellulose 59.5 grams Methyl Ethyl Ketone 10.
