  • Coated thermally printable material and method of producing the same
    Patent number: 5141914
    Abstract: Disclosed is a heat-sensitive recording material useful in the manufacture of thermal paper and thermal labels. The material comprises a cellulosic or other suitable substrate, a thermally imprintable color-producing layer, and a protective layer over the color-producing layer. It may also include a second protective layer and/or a pressure-sensitive adhesive layer, on the surface of the substrate opposite from the color-producing layer, and a releasable liner covering the adhesive layer. The color-producing layer includes a basic, acid-neutralizing agent for both reducing background discoloration during manufacturing and increasing image definition. The protective layer comprises a cross-linked binder and fluorochemical surfactant-treated hydrocarbon or fluorocarbon particles as a friction reducing material.
    Type: Grant
