Abstract
A transfer ribbon for applying a film of a cover material to a substrate, especially a paper substrate provided with markings to be covered or to be provided with a stripe of color from a coloring agent contained in the cover material, has a carrier-foil strip to which a cover layer is applied and an adhesive layer applied to that cover layer. The adhesion between the cover layer and the foil is less than the adhesion between the cover layer and the adhesive layer so that when the adhesive side of the ribbon is pressed against the substrate, the foil can be withdrawn to leave the cover layer, containing the coloring agent, thereon.
