  • Patent number: 6582789
    Abstract: A surface protective film which can be used in the production of components associated with a liquid crystal display such as a polarizer to improve productivity and yields since no air bubbles are trapped when stuck to a substrate having unevenness in the surface and since the adhesion is low and a change of the adhesion with the passage of time is small and which can be highly transparent and improve inspectability by using a polyester film having little particles as a base material. It is treated by an antistatic agent or a release agent the surface of the surface protective film opposite to the surface in which the adhesive layer is formed, as a result, control of static electrification in case the surface protective film is peeled off and removal of the dust adhering to the surface can be made easy.

  • Patent number: 6497942
    Abstract: A gyricon or twisting-particle display based on nonspheroidal (e.g., substantially cylindrical) optically anisotropic particles disposed in a substrate. The particles can be either bichromal or polychromal cylinders, preferably aligned parallel to one another and packed close together in a monolayer. A rotatable disposition of each particle is achievable while the particle is thus disposed in the substrate; for example, the particles can already be rotatable in the substrate, or can be rendered rotatable in the substrate by a nondestructive operation performed on the substrate. In particular, the substrate can be made up of an elastomer that is expanded by application of a fluid thereto so as to render the particles rotatable therein. A particle, when in its rotatable disposition, is not attached to the substrate. The close-packed monolayer configuration of particles provides excellent brightness characteristics and relative ease of manufacture as compared with certain other high-brightness gyricon displays.

    Abstract: There are provided a hologram laminate and a hologram label which do not involve any problem in the production process per se of forging preventive labels using a volume hologram, can provide a reliable process of the attainment of forgery preventive effect, and can make difficult to notice the signs of the forgery preventive processing. In applying a protective film 108 onto a hologram 107 through a second pressure-sensitive adhesive 109, the adhesive strength is partially varied. By virtue of this construction, upon separation of the protective film 108, the second pressure-sensitive adhesive 109 is partially left on the hologram 107, so that the fact of the separation can be found out. Likewise, the adhesive strength of a first pressure-sensitive adhesive 106 can be partially changed. Further, the adhesive strength of the first pressure-sensitive adhesive 106 is larger than 1% tensile strength of the hologram 107.

  • Patent number: 6248414
    Abstract: A unitary stack of paper sheets has alternating individual paper sheets and individual release liners which are loosely bonded together in a manner whereby an individual paper sheet is easily removed and used as a base. Each paper sheet in the unitary stack has a pressure sensitive adhesive partially covering each face thereof in approximate aligned areas of the respective faces. A back face of the individual sheet is adhered to a substrate while a front face holds an item for posting. In use, an individual paper sheet is readily removed from the unitary stack, adhered on its back face to the substrate, and then an item posted on its front face.

  • Patent number: 6245400
    Abstract: A release lined pressure sensitive adhesive flexible graphite sheet article is provided having low thermal resistance properties comparable to the flexible graphite material itself when compared to prior art PSA sheet products and wherein the release liner is easily removed with the sheet is to be used without any significant delamination of the flexible graphite. The flexible graphite sheet comprises a flexible graphite substrate, an adhesive primer coating thereon, a pressure sensitive adhesive coating on the adhesive primer coating and a release liner applied to the pressure sensitive adhesive coating. Double sided pressure sensitive adhesive flexible graphite sheets can also be made using the method of the invention.

  • Patent number: 6242510
    Abstract: A pressure sensitive adhesive composition comprised of a substantially tacky polymer containing a number of prismatic or holographic platelets. When the composition is applied to a substrate, the platelets align themselves in a planar fashion parallel to the broad face of the surface on which the coating is applied. The resulting composition layer is transparent except for the platelets that refract and reflect the light striking the platelets back towards an observer. The color of the reflected light changes as the angle at which the platelets are viewed is changed. In this manner, the platelets in the coating provide an overall aesthetically pleasing appearance for the coated material that adds distinctiveness to decorative labeling, as well as to the objects on which the labeling is placed and other suitable types of laminations in which the adhesive coating may be used.

  • Patent number: 6221453
    Abstract: A fluorescent label can be used to identify the location of variations, e.g. radial variations, in a pneumatic tire so the tire can be precisely mixed and matched with other components such as tire rims which may have compensating variations. The fluorescent label desirably includes a release backing, a pressure sensitive adhesive to bind said label to a tire, a nontransparent face sheet that reflects a substantial portion of incident light back towards its source, transparent top layer which contains one or more fluorescent dye(s) disproportionately present in the surface portion of the layer and preferably in the layer nearest the adhesive side. The location of the largest portion of the fluorescent dye is important as commercial labels with the dye on the exterior surface suffer from fluorescent reading losses apparently due to migration of mobile molecules from other tires stored in contact with the label's exterior surface.
