  • Patent number: 6706355
    Abstract: There is provided an adhesive article including (a) a radiation curable adhesive layer comprising an acrylic pressure sensitive adhesive and, optionally, an acrylated urethane polymer; and (b) a transparent carrier layer. The adhesive article may contain a radiation curable epoxy layer between the radiation curable adhesive layer and the transparent carrier layer. This adhesive article is particularly useful in preparing protective coatings on color filters for use in a liquid-crystal display panel structure. The radiation curable epoxy layer and radiation curable pressure sensitive adhesive are applied to the color filter and then exposed to UV radiation. The UV radiation exposure transforms the pressure sensitive adhesive from a removable adhesive to a permanent adhesive. The color filter with the UV cured adhesive layer is then baked to fully cure the adhesive layer and to transform the adhesive further into a near structural adhesive.

  • Patent number: 6482488
    Abstract: This invention relates to a method of repairing one or both sides of an optically damaged substrate such as rigid glass or plastic window, signage or displays. The invention also relates to the repaired substrates. This invention also relates to an article comprising a transparent stack of sheets that may be applied, for example, to protect said repaired substrates such as glass or plastic windows, signage or displays. A topmost sheet can be peeled away after it is damaged to reveal an undamaged sheet below. The invention also relates to the protected substrates and a method of protecting substrates such as glass or plastic windows, signage and displays from vandalism or other surface damage by adhering the stack of sheets to the substrate to be protected and subsequently pulling a topmost sheet away from the stack after it becomes damaged.

  • Patent number: 6461725
    Abstract: A finely foamed pressure-sensitive adhesive tape or sheet possessing a pressure-sensitive adhesive layer having a fine cell size and cell wall thickness is disclosed. The tape or sheet is obtained by impregnating the pressure-sensitive adhesive tape or sheet with carbon dioxide in a liquid state or a supercritical state, and reducing the pressure to foam the pressure-sensitive adhesive layer. The main component of the pressure-sensitive adhesive layer is, for example, an acrylic resin or a rubber-based resin. The method provides a finely foamed pressure-sensitive adhesive tape or resin possessing a pressure-sensitive adhesive layer having a fine cell structure such that an average cell size d is from 0.01 to 1000 &mgr;m, an average cell wall thickness t is from 0.01 to 2000 &mgr;m, and the ratio t/d is in the range of from 0.5 to 3.5.

  • Publication number: 20020136853
    Abstract: The present invention provides an acrylic resin laminated film comprising a soft layer formed of an acrylic resin incorporated with rubber particles and having a flexural modulus of about 1,300 MPa or less, and a hard layer formed of an acrylic resin having a flexural modulus of about 1,800 MPa or more on at least one side of the soft layer, wherein the hard layer has a thickness of about 0.1 to about 30 &mgr;m and a ratio of the thickness of the hard layer to the overall thickness of the laminated film is about 50% or less. This acrylic resin laminated film has moderate surface hardness and flexibility and hence is capable of providing for a molding with less whitening when subjected to a molding or forming process including bending or stretching.

  • Patent number: 6436499
    Abstract: The present invention is directed to a cold seal package that includes constructions wherein two substrates, or two portions of one substrate, are sealingly engaged to one another using a substantially natural latex rubber-free contact adhesive. The two substrates can be easily peeled apart without substantial damage to the substrates. Furthermore, the substrates cannot typically be resealed, or refastened, once peeled apart. That is, the cold seal formed by the adhesive between the substrates is substantially non-refastenable. Advantageously, a cold seal package of the present invention is particularly well suited for aseptic delivery of packaged goods, such as bandages, dressings, and the like.

  • Patent number: 6432501
    Abstract: The problems of applying ink jet inks to various known coating surfaces so as to overcome smearing, poor resolution and attack by water etc., is overcome by the use of the new ink jet receptive media. The media comprises in combination: (1) a waterproof ink jet receptive coating, (2) a primer coating, (3) a non-porous substrate, (4) a pressure sensitive adhesive coating, (5) a silicone coating and (6) a backer layer. The receptive coating comprises the combination of: (1) binder, (2) charge control agent, (3) cross-linking agent, (4) adhesion enhancing agent and (5) dispersant. The absorption of the ink jet ink to the substrate is maximized, thus attracting and fixing the ink and providing a waterproofing effect.
