  • Patent number: 5366952
    Abstract: A double-surface heat-sensitive record material is disclosed that provides separable, thermally printed surfaces. The invention includes a first heat-sensitive record surface having an exposed heat-sensitive record layer on one surface, a pressure-sensitive adhesive layer, and release liner on an opposed surface. A second heat-sensitive record surface includes a second heat-sensitive record layer on an exposed surface. This second record surface is secured to the first record surface, by a binder layer, to form a double-surface heat-sensitive record material having opposed, exposed heat-sensitive record layers. A thermal imager or printer can then print on both exposed heat-sensitive record layers. The release liner enables the two record layers to be separated, forming first and second printed surfaces, wherein the first printed surface has an exposed pressure-sensitive adhesive layer so that it can be readily used as a label, while the second printed surface may be used as a receipt.
