<p>Disclosed is a heat-sensitive recording material useful in the manufacture of thermal paper and thermal labels (16). The material comprises a cellulosic or other suitable substrate (10), a thermally imprintable color-producing layer (11), and a protective layer (12) over the color-producing layer. It may also include a second protective layer (13) and/or a pressure-sensitive adhesive layer (14), on the surface of the substrate opposite from the color-producing layer, and a releasable liner (17) covering the adhesive layer. Color-producing layer (11) includes a basic, acid-neutralizing agent for both reducing background discoloration during manufacturing and increasing image definition. Protective layer (12) comprises a cross-linked binder and fluorochemical surfactant-treated hydrocarbon or fluorocarbon particles as a friction reducing material. Label (16) may be printed with a suitable ink with bar code or alpha-numeric character (25).</p> |
