Abstract
An overlappingly overstrikeable ribbon is described having a carrier film (2) and an ink-releasing coating (3) in the form of a plastic matrix applied thereto, which contains at least one fatty dye and/or oil-soluble dye and optional carbon black and/or other ink pigments, as well as further conventional additives. According to FIG. 1 the ink-releasing coating (3) can be subdivided into differently colored coatings (4a, 4b and 4c) representing the three primary colors and a black coating (4d) for producing color prints. The ink-releasing coating contains no fillers and contains a polyethoxylated fatty acid ester of a polyhydric alcohol as a solvent for the dye(s). This ribbon has advantages when used in continuously full cassettes which are more particularly used in matrix printing systems.
