Abstract: A thermosensitive recording label includes a thermosensitive color-forming layer disposed on one side of a substrate for creating a display of images when the temperature of selected portions of the thermosensitive color-forming layer are heated above an activated temperature. A remoistenable type adhesive is disposed in viscous form on an opposite side of the substrate and dried thereon without heating the thermosensitive color-forming layer above its activation temperature. The remoistenable adhesive does not include any organic solvents or substances which may cause bleed-through to the substrate and into the color-forming layer. Therefore, a barrier layer is not necessary therebetween. In addition, a protective, or barrier layer, may be disposed on top of the thermosensitive color-forming layer to prevent fading or discoloration by exterior contaminants.

Abstract: Covering a rigid but pliable, smooth surface with a one-sided matte embossed polyethylene film, where the non-embossed smooth side of the film is in direct contact with the smooth surface being covered. Adhesion of the smooth side of the film to the smooth surface to which it is applied is effected much like a vacuum adhesion as seen when a drop of water is placed between two sheets of glass. The embossed side of the film forms microscopic air pockets when rolled upon itself which prevents blocking. This feature allows the non-embossed side to be made as smooth as possible without the need for an anti-blocking agent.
