Abstract
A thermosensitive recording label includes a thermosensitive color-forming layer disposed on one side of a substrate and a heat reflecting layer disposed on another side of the substrate and a delayed action adhesive disposed on the heat reflecting layer. The thermosensitive recording label may be manufactured and used without a backing sheet, thus considerably reducing the weight and volume of the label. In use, the thermosensitive recording label is drawn from a roll or stack and the delayed action adhesive activated by a heat lamp, or the like, to place it in a tacky condition for placement on goods. The heat reflecting layer disposed between the delayed action adhesive and the thermosensitive color-forming layer prevents activation of the color-forming layer during heating of the delayed action adhesive.
