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.
Claims24
A block out label comprising:
- (a) a paper facestock having an upper surface and a lower surface;
- (b) a pigmented layer, the pigmented layer having an upper surface and a lower surface, wherein the pigmented layer is located beneath the lower surface of the paper facestock and is formed from precipitated calcium carbonate and blue pigment;
- and
- (c) a pressure sensitive adhesive layer, the pressure sensitive adhesive having an upper surface and a lower surface, wherein the pressure sensitive adhesive layer is located beneath the lower surface of the pigmented layer, such that:
- (d) the label has:
- (i) an opacity greater than or equal to approximately 94.8 percent, and
- (ii) one or both of the following:
- (1) a whiteness index greater than or equal to approximately 155, and
- (2) a brightness greater than or equal to approximately 90.2%, a CIELAB L* greater than or equal to approximately 92.5, and a CIELAB b* less than or equal to approximately −0.91,
- wherein the opacity, the whiteness index, and the brightness are measured at the upper surface of the facestock, and
- wherein the combination of the elements (a) through (c) of the label comprising the characteristics of (d) yields the block out label that blocks out one or more pieces of indicia that lies beneath the lower surface of the pressure sensitive adhesive layer once the block label is placed there over.

A block out label comprising:
- (A) a paper facestock having an upper surface and a lower surface;
- (B) a pigmented layer, the pigmented layer having an upper surface and a lower surface, wherein the pigmented layer is located beneath the lower surface of the paper facestock and is formed from precipitated calcium carbonate and blue pigment;
- and
- (C) a pressure sensitive adhesive layer, the pressure sensitive adhesive having an upper surface and a lower surface, wherein the pressure sensitive adhesive layer is located beneath the lower surface of the pigmented layer, such that:
- (D) the label has:
- (i) an opacity greater than or equal to approximately 94.8 percent, and
- (ii) one or both of the following:
- (1) a whiteness index greater than or equal to approximately 155, and
- (2) a brightness greater than or equal to approximately 90.2%, a CIELAB L* greater than or equal to approximately 92.5, and a CIELAB b* less than or equal to approximately −0.91,
- wherein the opacity, the whiteness index, and the brightness are measured at the upper surface of the facestock,
- wherein the paper facestock further comprises at least one additive selected from titanium dioxide, precipitated calcium carbonate, ash, or any suitable combinations thereof, and
- wherein the combination of the elements (A) through (C) of the label comprising the characteristics of (D) yields the block out label that blocks out one or more pieces of indicia that lies beneath the lower surface of the pressure sensitive adhesive layer once the block label is placed there over.

A block out label sheet comprising:
- (i) a paper facestock having an upper surface and a lower surface;
- (ii) a pigmented layer, the pigmented layer having an upper surface and a lower surface, wherein the pigmented layer is located beneath the lower surface of the paper facestock and is formed from precipitated calcium carbonate and blue pigment;
- (iii) a pressure sensitive adhesive layer, the pressure sensitive adhesive having an upper surface and a lower surface, wherein the pressure sensitive adhesive layer is located beneath the lower surface of the pigmented layer;
- and
- (iv) a release liner layer having an upper surface and a lower surface, wherein the release liner layer is located beneath the lower surface of the pressure sensitive adhesive layer, such that:
- (v) elements (i) through (iii) form a block out label that has:
- (a) an opacity greater than or equal to approximately 94.8 percent, and
- (b) one or both of the following:
- (1) a whiteness index greater than or equal to approximately 155, and
- (2) a brightness greater than or equal to approximately 90.2%, a CIELAB L* greater than or equal to approximately 92.5, and a CIELAB b* less than or equal to approximately −0.91,
- wherein the opacity, the whiteness index, and the brightness are measured at the upper surface of the facestock, and
- wherein the combination of the elements (i) through (iii) of the label comprising the characteristics of (v) yields the block out label that blocks out one or more pieces of indicia that lies beneath the lower surface of the pressure sensitive adhesive layer once the block label is placed there over.
