Title: Self-contained thermal transfer label

Abstract: A self-contained thermal transfer label is disclosed herein. The product is formed as paper stock having an area of release material applied to a surface portion thereof. A layer of adhesive material is applied upon the release material. A thermal transfer donor ribbon is mated to the label by the area of adhesive material. The donor ribbon is treated, prior to mating with the label, such that the surface tension at the donor ribbon is modified to a level substantially different from that of the release material. As a consequence, when the donor ribbon is removed from the label, after printing on the label, the adhesive remains secured to the donor ribbon, rather than the underlying label. A result is a label that may support a higher quality image, but without adhesive residue after the donor sheet is peeled away. Various applications of the product are disclosed herein.
