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and the adhesive layer so that when the adhesive side of the ribbon is pressed against the substrate, the foil can be withdrawn to leave the cover layer, containing the coloring agent, thereon.
Claims11
A multilayer flexible transfer ribbon for transferring a cover material to a substrate upon contact therewith, said ribbon comprising:
- a flexible carrier-foil strip;
- a synthetic-resin bonded cover layer containing said cover material and bonded to said flexible carrier-foil strip;
- and
- an adhesive layer of an elastic, tacky pressure-contact adhesive on said synthetic-resin-bonded cover layer and bonded thereto with a bonding force greater than a bonding force bonding said synthetic-resin-bonded cover layer to said carrier-foil strip whereby, upon application of said ribbon to a substrate, said adhesive layer retains said cover layer thereon while said carrier-foil strip is drawn away, thereby covering an area of said substrate with said cover material, said adhesive layer being an organic polymer selected from the group consisting of rubber, polyvinylether, polyvinylisobutylene, acrylate-based polymer and mixtures thereof, and wherein said adhesive layer and said cover layer have relative thicknesses in a ratio of about 1:6 to about 1:12.
