Abstract

An adhesive label with a water-based release coating and methods for applying the water-based release coating to the adhesive label are provided. The water-based release coating is a non-silicon based formulation having a fluorochemical. The water-based release coating can be applied in a single-pass process or a double-pass process when manufacturing the adhesive label.

First claim

The invention claimed is:

1. An adhesive label, comprising:
a substrate;
a release coating disposed on a front surface of the substrate, the release coating comprising a water miscible fluorochemical mixture, wherein a first component of the water miscible fluorochemical mixture anchors into the release coating while a second component of the water miscible fluorochemical mixture remains outside of the release coating; and
an adhesive disposed on a second surface of the substrate;
wherein the release coating is disposed on the front surface instead of a silicone release coating;
wherein the fluorochemical mixture includes a hydrophilic tail and a hydrophobic tail.

2. The adhesive label of claim 1 further comprising a thermal print layer under the release coating on the front surface.

3. The adhesive label of claim 2 , wherein the substrate is adapted to prevent activation of the thermal print layer when heat is applied to the second surface.

4. The adhesive label of claim 3 , wherein the thermal print layer is a thermal receptive coating suitable for thermal transfer when heat is applied to the front surface.

5. The adhesive label of claim 3 , wherein the thermal print layer comprises thermal sensitive coatings adapted to change color upon activation of heat from direct thermal printing applied to the front surface.

6. The adhesive label of claim 1 , wherein the adhesive is a water-based adhesive.

7. The adhesive label of claim 1 , wherein the substrate is a thermochromic paper.

8. The adhesive label of claim 1 , wherein the adhesive comprises adhesive patches deposited on the second surface.

9. The adhesive label of claim 1 , wherein the adhesive is a heat-activated adhesive.

10. A label comprising:
a substrate;
a water-based release coating disposed on a first surface of the substrate, wherein the water-based release coating comprises a fluorochemical component, wherein the water-based release coating with the fluorochemical component comprises a first component that anchors into the water-based release coating and a second component that remains outside of the water-based release coating; and
an adhesive coating disposed on at least a portion of a second surface of the substrate;
wherein the water-based release coating is disposed to the front surface instead of a silicone release coating;
wherein the fluorochemical component includes a hydrophilic tail and a hydrophobic tail.

11. The label of claim 10 , wherein the substrate is adapted to prevent activation of a thermal print layer disposed on the first surface when heat is applied to the second surface.

12. The label of claim 10 , wherein the substrate is a thermochromic paper.

13. The label of claim 10 , wherein the water-based release coating with the fluorochemical component is a non-silicon-based release coating.

14. The label of claim 10 , wherein the water-based release coating with the fluorochemical component is adapted to be applied to the first surface via a press instead of a coater.

15. The label of claim 14 , wherein the water-based release coating with the fluorochemical component is adapted prevent wet interaction during drying on the press of the water-based release coating with the fluorochemical component on the first surface.

16. A label comprising:
a substrate comprising a first side and a second side;
a first coating and a water-based release coating disposed on the first side, wherein the water-based release coating comprises a fluorochemical component, wherein the water-based release coating is situated on top of the first coating, and wherein the water-based release coating with the fluorochemical component comprises a first component that anchors into the water-based release coating and a second component that remains outside of the water-based release coating; and
an adhesive coating disposed on the second side;
wherein the water-based release coating is applied to the first side instead of a silicone release coating;
wherein the fluorochemical component includes a hydrophilic tail and a hydrophobic tail.

17. The label of claim 16 , wherein the first coating is a thermal-transfer print coating.

18. The label of claim 16 , wherein the first coating is a direct-thermal print coating.

19. The label of claim 16 , wherein the fluorochemical component is water miscible and includes a C-6 backbone.
