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.
