ABSTRACT:
Product and process for heat transfer labeling. A transfer layer containing a design print is superimposed upon a contoured release layer that is desirably imprinted on a carrier. When the carrier, together with the release layer and the transfer layer are applied to an object to be labeled and heated, both the release layer and the transfer layer become molten and the transfer layer becomes adhered to the object being labeled. The release layer and the transfer layer are immiscible when in a molten state. The desired immisciblity can be achieved by the inclusion of a barrier layer between the transfer layer containing the design print and the release layer.
