Abstract (en)
[origin: EP0352525A2] A thermal ink ribbon, especially a thermal carbon ribbon, is described which has a conventional support and a layer of a melt-on ink formed on one side of the support, a separating layer being provided between the surface of the support and the layer of melt-on ink. The special characteristic of this thermal ink ribbon is that the separating layer contains water-releasing agents dispersed in a binder. Such a thermal ink ribbon is distinguished in that the melt-on ink can be readily and completely detached in the area of the embossed thermal symbol during the thermal printing process.
