Abstract (en)

[origin: EP0304673A1] A thermally sensitive ink ribbon for thermal transfer printing which can be overwritten many times having a layer of fusible ink on one side of a carrier film, where the fusible ink contains a wax or a wax-like substance, a colorant, a thermoplastic binder and, if desired, other additives and the thermoplastic binder represents the support substance, in the voids of which particles of a fat-soluble dye, a pigment and a wax or wax-like substance in finely divided solid form exist alongside one another. It can be produced by applying an aqueous coating dispersion which contains the thermoplastic binder, the fusible wax or fusible wax-like substance and a fat-soluble dye in finely divided solid form to the base film of the thermally sensitive ink ribbon and evaporating the aqueous portion of the dispersion. It can be manufactured without using environmentally disadvantageous solvents and, moreover, can be overwritten 5 to 15 times without deterioration of the print quality.
