Abstract
This invention relates to a heat-sensitive recording material. More particularly, this invention relates to a heat-sensitive recording material including a solvent-resistant and friction-reducing protective layer useful in the manufacture of adhesive-backed heat-sensitive labels and other thermally sensitive paper stock used in printers and facsimile equipment. The protective layer is non-acidic and has an improved resistance to background discoloration.
