  • Publication number: 20050271850
    Abstract: A coated film is provided having a textured film with a top surface and a bottom surface, wherein at least one LAB coated area and at least one uncoated area are on the top surface of a textured film, and the appearance of the coated and uncoated areas on a textured film is visibly uniform and generally provides a coated film that has a surface that has visually indiscernible areas, even when at least one portion of the films is coated with particulate filled LAB, and the remainder of the film is uncoated.

  • Publication number: 20030098906
    Abstract: The invention provides a method for imparting an image to a substrate that includes imparting an image to an image transfer sheet having an image receptive layer releasably attached to a carrier sheet, wherein the imaged side of the image transfer sheet is the side containing the image, and the non-imaged side is the opposite side, contacting the imaged side of the image transfer sheet with the substrate, applying localized pressure to the non-imaged side of the image transfer sheet, and removing the carrier sheet wherein removal of the carrier sheet imparts the portion of the imaged image receptive layer, in a discontinuous fashion, where localized pressure was applied to the non-imaged side of the image transfer sheet.

  • Patent number: 6200596
    Abstract: Skin treatments which do not interfere with the ability of pressure-sensitive adhesives to adhere to skin are disclosed. The treatment compositions include an acrylate polymer dissolved in an emollient oil. Use of the treatment provides a method of protecting mammalian skin without interfering with the application of medical adhesive dressings.

  • Patent number: 5652296
    Abstract: A water-based adhesive comprising water-soluble polymers having carboxy groups and quaternary ammonium groups wherein the polymers can be derived by copolymerizing one or more unsaturated aliphatic carboxylic acid monomers, such as acrylic acid and/or methacrylic acid, and alkylaminoalkyl(meth)acrylate or alkylaminoalkyl(meth)acrylamide, such as dimethylaminoethyl methacrylate or dimethylaminopropylmethacrylamide and the water-based adhesive is a viscous liquid that is colorless, relatively odorless, and free of organic solvents.
