A thermosensitive recording label includes a substrate, a thermosensitive color-forming layer disposed on one side of the substrate, a protective layer disposed on the thermosensitive color-forming layer, a pressure-sensitive hot melt adhesive layer disposed on another side of the substrate and a releasable backing sheet disposed on the pressure-sensitive adhesive layer. The use of a hot melt adhesive layer enables the thermosensitive label to be placed on plastic films without migration of plasticizers in the film from migrating into the color-sensitive layer. The hot melt adhesive not only prevents such plasticizers migration, but enables the labels to be placed on beef products without discoloration of the beef beneath the label.
