Abstract
The present invention includes a label, a label sheet and a method for manufacturing the label. The label includes a paper facestock having first and second surfaces and a layer of pressure sensitive adhesive proximal to the second surface. The label can be adhered to a substrate having pre-applied indicia to cover the indicia and the label is opaque enough to prevent the viewing of the covered indicia while matching the color of the substrate.
Claims31
A method of making a block out label, the method comprising the steps of:
- (a) providing at least one light blocking additive;
- (b) combining the at least one light blocking additive with at least one pressure sensitive adhesive to form a light-blocking pressure sensitive adhesive layer, the pressure sensitive adhesive layer having a top surface and a bottom surface;
- (c) providing at least one paper facestock layer having an uncoated top surface and a bottom surface, wherein the facestock layer comprises at least one opacity-inducing additive therein;
- and
- (d) placing the at least one paper facestock layer onto to upper surface of the pressure sensitive adhesive layer such that the bottom surface of the paper facestock layer and the top surface of the pressure sensitive adhesive layer are in contact with one another;
- wherein the at least one light blocking pressure sensitive adhesive layer is designed to block, reflect and/or absorb light due to the inclusion of one or more additives selected from carbon black, metallic flakes, one or more metallic particles in combination with one or more dark dispersants, one or more dark dyes, or combinations of two or more thereof,
- wherein the opacity-inducing additive of the at least one paper facestock layer is selected from titanium dioxide, calcium carbonate, barium sulfate, aluminum trihydrate, talc, zinc sulfide, diatomaceous silica, clay, chalk, ash, finely dispersed gases, stilbenes, azoles, coumarins, pyrazenes, napthalimides, or a combination of any two or more thereof, and
- wherein the block out label has an opacity, measured at the top uncoated surface of the at least one paper facestock layer, greater than or equal to about 94.8 percent due to the combination of the at least one light blocking pressure sensitive adhesive layer and the at least one paper facestock layer having therein at least one opacity-inducing additive.

The method of claim 7, wherein the pigmented layer includes precipitated calcium carbonate and blue pigment.
A block out label comprising:
- (i) a paper facestock having an uncoated top surface and a bottom surface, wherein the paper facestock layer contains at least one opacity-inducing additive;
- and
- (ii) a pressure sensitive adhesive layer having a top surface and a bottom surface, wherein the pressure sensitive adhesive layer contains at least one light blocking additive and wherein the top surface of the pressure sensitive adhesive layer is in contact with the bottom surface of the facestock layer,
- wherein the combination of the light blocking pressure sensitive adhesive layer and the paper facestock layer having therein at least one opacity-inducing additive yield a block out label having an opacity, measured at the top uncoated surface of the paper facestock layer, greater than or equal to about 94.8 percent.
1 more element
A block out label comprising:
- (I) a paper facestock having an uncoated top surface and a bottom surface, wherein the paper facestock layer contains at least one opacity-inducing additive;
- (II) a pressure sensitive adhesive layer having a top surface and a bottom surface, wherein the pressure sensitive adhesive layer contains at least one light blocking additive and wherein the top surface of the pressure sensitive adhesive layer is located below the bottom surface of the facestock layer;
- and
- (III) a pigmented layer having a top surface and a bottom surface, wherein the pigmented layer is located between the bottom surface of the paper facestock layer and the top surface of the at least one light blocking pressure sensitive adhesive layer,
- wherein the combination of at least the light blocking pressure sensitive adhesive layer and the paper facestock layer having therein at least one opacity-inducing additive yield a block out label having an opacity, measured at the top uncoated surface of the paper facestock layer, greater than or equal to about 94.8 percent.
