Abstract:
Providing a non-silicone release sheet that has a good release property and in which blocking does not occur even after long periods of storage in a wound roll-like shape.A release sheet 10 is constructed by laminating an undercoat layer 12 and a release agent layer 13 on a release sheet base 11. The release agent layer 13 is formed of a polyolefin resin composition containing a polyolefin thermoplastic resin having density of 0.800 to 0.905 g/cm3 and polymerized with a multi-site catalyst. In the release agent layer 13, an average modulus of elasticity of the release agent layer at 23° C. in 50 to 1000 nm depths from the surface thereof, as measured by Nano Indentation Method, is 0.1 to 0.3 GPa, and a roughness is formed on the surface so that the surface roughness Ra1 thereof is 100 to 700 nm.

Abstract:
A label assembly including one or more dissolvable thermal direct adhesive labels mounted on a release liner. According to one embodiment, each label includes a base layer, a thermal direct layer, an adhesive layer, and a barrier layer. The base layer, which has an upper surface and a lower surface, is water-dissolvable and may be made of a water-dissolvable paper. The thermal direct layer is positioned directly over the upper surface of the base layer and functions in the conventional manner to produce markings therein in response to heat. The adhesive layer is water-dissolvable and is positioned below the lower surface of the base layer. The barrier layer, which is positioned directly below the lower surface of the base layer and directly over the adhesive layer, serves to prevent migration of the adhesive layer through the base layer and into contact with the thermal direct layer.

A release liner 10 comprising a polymeric film substrate 11, typically PET film, having a transparent layer 12 of electrically conductive polymer, preferably a PEDOT-PSS (Polyethylenedioxythiophene/polystyrenesulphonic acid), formed on one side thereof, the conductive polymer layer 12 being over coated with a transparent layer 13 of a curable silicone polymer or copolymer.
Abstract:
An adhesive tape with an antistatic release coating is provided. The release includes an antistatic additive made from a reaction product of from about 1 to 30 parts hydrophilic monomer, from about 5 to 40 parts ionic monomer, and from about 20 to 80 parts hydrophobic monomer. A release agent can also be added to the release coating. The adhesive tape does not recoil upon itself when unrolled from the tape core.

Abstract:
Ink-imprintable release coating compositions are described which comprise a polymer comprising a polyurethane, a fluoroacrylate polymer or copolymer, or an addition cured or a condensation cured silicone polymer containing dispersed and/or emulsified resin particles, resin particle domains, or both, and, optionally, inorganic particles. The resin particles comprise resins which are different from the polymers and the resins comprise polyurethanes, polyamides, and polyureas. Ink-imprintable label, tape and stamp constructions also are described which comprise a plurality of contiguous labels, tapes or stamps in a roll or stacked sheet configuration without an independent release liner wherein the labels, tapes and stamps have a pressure-sensitive adhesive on the back surface and a cured ink-imprintable release coating on the face surface.
Abstract:
The present application relates to a method and device for making a magnetically mountable substrate construction from a selected substrate for magnetic mounting to a structure including magnetizable material. The magnetically mountable substrate may be formed from a pressure sensitive adhesive magnetic sheet material which includes a flexible magnetic substrate having a first major surface and a second major surface, with a pressure sensitive adhesive layer adhering to the first major surface and a release layer, such as silicone release layer, adhering to the second major surface. The magnetic sheet may be provided in the form of continuous lengths wound in a roll with the release layer in contact with the pressure sensitive layer of an adjacent winding to facilitate unwinding without delamination.

Abstract:
Applied to a substrate such as paper banknotes is a thread which includes a PET carrier layer with release layers on both surfaces of the carrier layer, and a metallic layer outward of one release layer. An adhesive layer lies outward of the metallic layer. When a substrate is brought into contact with the adhesive layer, the result is to bond the metallic layer to the substrate. Following this, the PET carrier layer is peeled away, leaving the metallic layer bonded to the substrate. An apparatus for accomplishing these steps includes means for bringing the substrate into contact with the adhesive layer, and means for peeling the PET carrier layer away so that it separates from the metallic layer at the adjacent release layer.
Abstract:
The present invention is a self-wound thermal transferable over-laminating (OL) tape, preferably for receiving a thermal transfer image from a thermal transfer ink ribbon and preferably using pressure-sensitive-adhesive (PSA). The preferred embodiment of the OL PSA tape comprises a layer of plastic film with two opposing sides. The first opposing side of the plastic film contacts a printable release coating comprising clear polyamide-carbamate receptive to wax-type, resin-type and wax-resin hybrid thermal transfer inks. The second opposing side of the plastic film contacts a pressure-sensitive-adhesive. The pressure sensitive adhesive is, preferably, acrylic adhesive.
