  • Patent number: 6162485
    Abstract: A system for forming fingerprints comprises a substrate bearing a designated print image-forming area and a localized coating of pressure-sensitive microcapsules containing a substantially colorless, image-forming reactant in the form of a color former or color-developer for forming a latent or visible image of a fingerprint in the designated print image-forming area. An image-developing device comprising a transparent film coated with a dual-functional adhesive composition comprising a pressure-sensitive adhesive containing an image-forming co-reactant in the form of a color developer or color former is used to form a protected visible image in the designated print image-forming area when applied to the fingerprint image.

  • Patent number: 6139953
    Abstract: A base material has a radiation-cured material prepared by curing a mixture of urethane acrylate oligomer and reactive dilute monomer, and also it shows a breaking elongation of more than 10%, preferably of more than 100%. The base material is used as a base sheet of an adhesive tape where an adhesive layer is formed on the base sheet. Accordingly, the novel base material and its manufacturing method in addition to an adhesive tape having such base material are provided. Furthermore, the adhesive tape has a flat surface without any fish-eye that causes the troubles of cracking, chip-scattering, and so on in the steps of back-grinding and dicing of the semiconductor wafer, and also the adhesive tape can be processed so as to have a predetermined thickness with high accuracy, compared with that of the conventional one.

  • Patent number: 6083616
    Abstract: An adhesive coating or layer has a differential height barrier structure deposited on the surface of one or both sides. Consequently, a highly aggressive adhesive formulation can be temporarily neutralized so as not to resist sliding of an item being positioned on the surface, until pressure is deliberately applied. Conversely, the adhesive system can be carried by decorative sheet material for easy application of the sheet material to cover a wall or floor, whereby the sheet can be slid into exact position without "sticking", before permanent adhesion. The present invention may be implemented by forming an array of discrete surface barrier structures which cover 10-30% of the active surface area of the adhesive. The barrier is preferably formed by an array of minute units of hard material or other discrete structures distributed on the adhesive surface and projecting therefrom by about 0.00025-0.0005 inch.

    Abstract: A decorative ribbon is provided with a controllable adhesive on portions of the underside, whereby the ribbon may be adhered to an article and removed from the article for relocating it on the article, if desired. The ribbon also is cut through along predetermined lines to form decorative design elements in the ribbon. The cut lines are interrupted by uncut portions of the ribbon, whereby the decorative design elements may be displaced out of the plane of ribbon along the cut lines by bending at the uncut portions, whereby to form stand-up decorative design elements which project outwardly from the ribbon while remaining attached to the ribbon by the uncut portions. A flare ribbon is formed by a plurality of longitudinally spaced, V-shaped, serrated perforation cut lines which allow the ribbon to be separated along the cut lines and flared laterally outward.

    Abstract: A game table fabric to be applied to the game table bed of a game table is provided, wherein the game table fabric comprises a woolen fabric having a nonpermanent releasable adhesive applied to a back side of the woolen fabric so that the game table fabric may be directly applied to the game table bed and the game table fabric of the present invention is readily repositionable during installation and removable after an extended period of use. The nonpermanent releasable adhesive is formed of a low tack polymeric material which is suitable for releasably adhering the game table fabric to the game table bed. By applying the game table fabric of the present invention directly to the game table bed, the use of additional glues or adhesives to adhere the game table fabric to the game table bed is essentially eliminated.

  • Patent number: 6074721
    Abstract: A temporary decal comprising a porous paper base coated with a water-soluble slip layer (e.g., dextrin gum) on which offset printing inks are directly imprinted using a high speed lithographic press. The inks are printed in a designated area only, in a desired image. A clear spot coating, preferably of an aqueous material, is then printed over the image area only. A contact adhesive is then spot printed over the image area of each decal, preferably using a silk screen press. A removable cover sheet, such as a silicone-coated sheet, is placed over the contact adhesive of each printed sheet of decals to keep the sheets from sticking together. The spot coating acts as a protective layer that keeps the contact adhesive from migrating to the surface of the decal after the finished temporary tattoo is applied to the skin. Without the spot coating, the surface of the decal would become sticky to the touch and the decal would come off faster because of friction with the surrounding environment.

  • Patent number: 5958802
    Abstract: The invention is basically ultra thin webbing that has been coated with a pressure sensitive adhesive that easily releases from the material. The webbing is manufacturer by producing an ultra thin webbing and the placing that webbing in a vat of pressure sensitive material that produces a coating on the webbing that enables the webbing to be attach to a material and also to be easily removed from the material. The webbing is coated such that the adhesive is on both side of the webbing and thus the webbing can be attached to materials on either side or both. The material is produced in sandwich form in which a release paper is attached by pressure to both sides. When an individual wishes to transfer a pattern to fabric the individual removes the release paper from one side of the webbing. Then the individual places the pattern on the webbing. Then one removes the other release paper and places the side not attached to the pattern against the fabric.

    Abstract: A paper-film laminate sealing tape for sealing a corrugated board carton or other article fabricated of recyclable material. The tape is composed of a base ply formed of high-strength, oriented synthetic plastic film whose opposing surfaces are corona-discharge treated to render them wettable and receptive to adhesives, and a paper face ply adhesively laminated to the base ply. The exposed surface of the base plastic-film ply is coated with a water-remoistenable adhesive, so that when this adhesive is moistened in a tape dispenser, the sealing tape can then be adhered to the carton. Since the remoistenable adhesive is coated on the plastic film ply which is water-impermeable, when this adhesive is moistened with water it remains in a moistened state in a condition to be applied to the carton for a relatively long "open-time" period.
