Abstract
The inked element which is preferably in ribbon form comprises a flexible plastics carrier of a thickness of from 5 to 15.mu., covered with a thermotransferable coating which is 2 to 6.mu. in thickeness. The mixture of the coating comprises a blend of thermoplastic resins of non-polymeric type with natural or synthetic waxes with a melting point of between 60.degree. and 80.degree. C. The waxes and the resins are so selected as to be compatible with each other and to provide a melting point of between 60.degree. and 80.degree. C. and a melt viscosity of between 50 to 1000 cps. The ribbon makes it possible to print at a printing rate of 40 to 120 characters/sec on papers having a Bendtsen roughness of 10 to 100 ml/min. The ribbon can be prepared with bands of different colors for multi-color printing.
