Abstract
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. A hot melt adhesive layer absent sufficient modifying resin to prevent migration thereof and unwanted color formation in the color-forming layer enables use of the hot melt adhesive in the label. In addition, the use of hot melt adhesive enables the labels to be placed on refrigerated beef products without discoloration of the beef beneath the label.
