Abstract: A label having a silicone-free (water-based) release coating and compatible adhesive patch is provided. The label includes a thermally coated substrate having a silicone-free substrate overlaid thereon of a first surface. A second surface includes a microsphere adhesive layer.

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.

Abstract: A combined receipt and label roll comprises a core, and a web having a longitudinally-extending axis and wound on the core along the axis. The web includes (i) a substrate having a front side and a back side opposite the front side, (ii) a thermally-sensitive coating disposed on the front side of the substrate, and (iii) a water-based microsphere adhesive disposed on the back side of the substrate along the web axis. The water-based microsphere adhesive comprises at least four separate adhesive patches. The at least four adhesive patches are both sized relative to each other and positioned relative to each other on the back side of the substrate such that additional tack desired can be obtained by increasing volume of the adhesive patches without having to increase coat weight of the adhesive patches.

Abstract: High tack repositionable adhesive obtained by combining an acrylic copolymer permanent pressure sensitive adhesive with a hydrophobically modified ethoxylate urethane (HEUR) thickener. The adhesive provides repositionable substrates, such as thermal paper, with high tack. Methods for preparing the high tack repositionable adhesive are provided.

Abstract: A paper substrate, particularly useful in wallboard tape applications containing PVOH on and/or in at least one surface of the paper, as well as methods of making and using the same. The use of the tape of the invention is used in conjunction with a joint compound that may contain no or reduced amounts of bonding agent.

Abstract: The present invention is directed to a method of efficiently maintaining or increasing brightness and whiteness of refined paper. In one aspect, the invention is directed to a method for substantially maintaining (or even increasing) brightness and/or whiteness of paper with increased pulp refining, the method including refining the pulp down to reduce the freeness at least about 100 CSF and adding a combination of an OBA and a carrier polymer to the paper surface in the size press in amounts sufficient to increase brightness and/or whiteness of the final paper. In another aspect, the invention is directed to a method of making paper from refined pulp that includes refining a cellulosic fiber suspension to reduce the freeness at least about 100 CSF and contacting the cellulosic fibers with at least one optical brightening agent (OBA) during or after the refining step prior to adding any additional wet end chemicals.

Abstract: A method for making printing paper comprising preparing an ink receiving surface coating composition which comprises an optical brightening agent (OBA), polyvinyl alcohol (PVOH) and a water soluble divalent salt, wherein the PVOH and OBA are added to the coating prior to the salt, and applying said coating composition onto at least one surface of said paper; and a surface coating composition which comprises a protected OBA and a water soluble divalent salt.
