A thermosensitive pressure sensitive label is provided which includes a substrate, a thermosensitive layer on one side of the substrate and a pressure sensitive adhesive layer disposed on an opposite side of the substrate. A barrier layer on top of the thermosensitive layer is covered with a silicone layer which enables the label to be rolled upon itself and unrolled without the use of a conventional backing sheet. In addition, the silicone layer enables color images formed in the thermosensitive layer to have a greater image density than the image density of color images that can be formed in the thermosensitive layer without the silicone layer being disposed thereover.

Non-laminate thermosensitive, pressure sensitive label and method of

A thermosensitive recording label includes a substrate, a thermosensitive color-forming layer disposed on one side of the substrate, a protective layer disposed on the thermosensitive color-forming layer, a pressure-sensitive hot melt adhesive layer disposed on another side of the substrate and a releasable backing sheet disposed on the pressure-sensitive adhesive layer. A hot melt adhesive layer absent sufficient modifying resin to prevent migration thereof and unwanted color formation in the color-forming layer enables use of the hot melt adhesive in the label. In addition, the use of hot melt adhesive enables the labels to be placed on refrigerated beef products without discoloration of the beef beneath the label.

Thermosensitive recording label

A thermosensitive recording label includes a thermosensitive color-forming layer disposed on one side of a substrate and a heat reflecting layer disposed on another side of the substrate and a delayed action adhesive disposed on the heat reflecting layer. The thermosensitive recording label may be manufactured and used without a backing sheet, thus considerably reducing the weight and volume of the label. In use, the thermosensitive recording label is drawn from a roll or stack and the delayed action adhesive activated by a heat lamp, or the like, to place it in a tacky condition for placement on goods. The heat reflecting layer disposed between the delayed action adhesive and the thermosensitive color-forming layer prevents activation of the color-forming layer during heating of the delayed action adhesive.

Heat insulated thermosensitive paper

A thermosensitive recording label includes a substrate, a thermosensitive color-forming layer disposed on one side of said substrate, a protective layer disposed on the thermosensitive color-forming layer, and electron beam setting printing ink disposed in a preselected pattern on the protective layer, a pressure-sensitive adhesive layer disposed on another side of the substrate and a releasing bold backing sheet disposed on the pressure-sensitive adhesive layer. A visible pattern is thereafter created by exposing the thermosensitive recording label to an electron beam to set, or cure the electron beam setting ink. The electron beam setting ink may be printed additionally on the substrate and the backing sheet to enable product coding information to be printed on the substrate as well as the printing of a manufacturer's logo on the backing sheet.

Releasable heat-sensitive label with E. B. setting printing ink

A thermosensitive recording label includes a substrate, a thermosensitive color-forming layer disposed on one side of the substrate, a protective layer disposed on the thermosensitive color-forming layer, a pressure-sensitive hot melt adhesive layer disposed on another side of the substrate and a releasable backing sheet disposed on the pressure-sensitive adhesive layer. The use of a hot melt adhesive layer enables the thermosensitive label to be placed on plastic films without migration of plasticizers in the film from migrating into the color-sensitive layer. The hot melt adhesive not only prevents such plasticizers migration, but enables the labels to be placed on beef products without discoloration of the beef beneath the label.
