Abstract
A multi-layer, pressure sensitive label having a print receiving layer, a sealant layer, a silicone layer, a varnish layer and an adhesive layer, whereby the pressure sensitive label is separable from a substrate between the silicone and a varnish layer leaving a transparent surface allowing the viewing or reading of any underlying text, message or indicia on the substrate.
Claims14
A separable label material formed in a continuous roll from which discrete labels are cut comprising:
- a layer of paper stock material reactive to a heat source for the development of an indicia in said paper stock material;
- 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;
- a release agent layer overlaid said layer of chemically treated paper stock material;
- 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 are separable from one another whereby said discrete label can be applied to a surface, and thereafter partially removed from said surface leaving said adhesive layer and said third coating layer on said surface.

A separable label assembly comprising:
- a paper stock material reactive to a heat source for the development of an indicia in said paper stock material, 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;
- a release agent layer overlaid said chemically treated stock material said assembly wound into continuous rolls from which a discrete separable lable may be cut;
- 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 are separable whereby said discrete separable label can be applied to a surface, and thereafter partially removed from said surface leaving said adhesive layer and said third coating layer on said surface.
