Abstract:
A continuous roll of labels comprising:a length of backing web; a sheet of paper stock material reactive to a heat source for the development of an indicia in said paper stock material, said paper stock material coextensive with said length of backing web, said paper stock material having coating layers applied thereto comprising: a first coating layer comprising a sealant layer applied to the underside of said paper stock material, said sealant layer formed by drying an adhesive to said underside of said paper stock materials; a second coating layer overlaying said sealant layer, said second coating layer being cured silicone; a third coating layer overlaid said cured silicone layer, said third layer being a cured layer of varnish; a pressure sensitive adhesive layer overlaid said varnish layer, said pressure sensitive adhesive layer adjacent said backing web; said first coating layer comprising a sealant being non-reactive with said paper stock material and said second coating layer so as to permit said paper stock material to develop said indicia from said heat source, said second coating layer and said third coating layer being substantially incompatible such that said second and third coating layer separate from one another when said labels, applied to a surface, are pulled therefrom but have shear and tensile strength therebetween greater than the tensile strength between said pressure sensitive adhesive layer whereby said label can be first separate from said backing web and then applied to articles, and thereafter removed from said articles leaving said adhesive layer and said third coating layer on said articles.
